Foskeia pelendonum thrived during the Early Cretaceous period, approximately 120 million years ago.
This newly identified species is part of the Rhabdodontomorpha, a group of ornithischian dinosaurs that existed primarily from the early to late Cretaceous period.
The diminutive dinosaur was roughly the size of a modern chicken, setting it apart from many of its larger ornithischian relatives.
“From the outset, we recognized the uniqueness of these bones due to their small size,” stated Dr. Fidel Torcida Fernández Baldor, a paleontologist at the Salas de los Infantes Dinosaur Museum.
“Remarkably, this study challenges established global theories regarding the evolution of ornithopod dinosaurs.”
“Miniaturization does not imply evolutionary simplicity. This skull is distinctive and highly specialized,” added Dr. Marcos Becerra from the National University of Córdoba.
“Foskeia pelendonum bridges a 70-million-year gap, serving as a small key to unlock a vast chapter of evolutionary history,” remarked Dr. Thierry Tortosa, a paleontologist at the Sainte-Victoire Nature Reserve.
“This is not a ‘mini’ iguanodon; it’s fundamentally different,” emphasized Dr. Tabata Zanesco Ferreira from the Federal University of Rio de Janeiro.
“Its anatomy is peculiar in a way that fundamentally alters the evolutionary tree,” said Dr. Penélope Cursado-Caballero from the University of La Laguna.
The fossilized remnants of at least five individuals of Foskeia pelendonum were excavated from the Vegaguete site in Burgos, Spain.
“This site is part of the Castrillo de la Reina Formation, located between Villanueva de Calazo and Salas de los Infantes,” the researchers noted.
Histological analysis confirmed that the largest specimen was a sexually mature adult.
“The microstructure of the bones suggests that at least one individual was an adult with a metabolic rate akin to that of small mammals and birds,” said Dr. Cohen Stein from Vrije Universiteit Bruxelles.
“Understanding growth and development is vital for comparing anatomical structures within Foskeia pelendonum and other species.”
“Juveniles often exhibit anatomical changes as they mature.”
Phylogenetic analysis indicates that Foskeia pelendonum is closely related to the Australian dinosaur Muttaburasaurus, extending the European clade Rhabdodontia.
“Our findings indicate that herbivorous dinosaurs comprise a natural group called Phytodinosauria,” stated Dr. Paul-Emile Dieudonné from the National University of Rio Negro.
“This hypothesis requires further examination with additional data.”
Despite its modest size, Foskeia pelendonum exhibits specialized dentition and postural changes during growth, adapting for rapid movement through dense vegetation.
“These fossils illustrate that significant evolutionary experiments occurred at both small and large body sizes,” Dieudonné concluded.
“The future of dinosaur research relies on recognizing the significance of small details.”
The discovery of Foskeia pelendonum is detailed in a research paper published in the journal Paleontology Papers.

A groundbreaking study conducted by paleontologists from the University of Bristol, the University of Manchester, and the University of Melbourne has uncovered that the giant ancestors of modern kangaroos possessed robust hindlimb bony and tendon structures, enabling them to endure the stress of jumping. This challenges the previous assumption that body size strictly limited this iconic locomotion.
Currently, red kangaroos represent the largest living jumping animals, averaging a weight of approximately 90 kg.
However, during the Ice Age, some kangaroo species reached weights exceeding 250 kg—more than double the size of today’s largest kangaroos.
Historically, researchers speculated that these giant kangaroos must have ceased hopping, as early studies indicated that jumping became mechanically impractical beyond 150 kg.
“Earlier estimates relied on simplistic models of modern kangaroos, overlooking critical anatomical variations,” explained Dr. Megan Jones, a postgraduate researcher at the University of Manchester and the University of Melbourne.
“Our research indicates that these ancient animals weren’t simply larger versions of today’s kangaroos; their anatomy was specifically adapted to support their massive size.”
In this new study, Dr. Jones and her team examined the hind limbs of 94 modern and 40 fossil specimens from 63 species, including members of the extinct giant kangaroo group, Protemnodon, which thrived during the Pleistocene epoch, approximately 2.6 million to 11,700 years ago.
The researchers assessed body weight estimates and analyzed the fourth metatarsal length and diameter (a crucial elongated foot bone for jumping in modern kangaroos) to evaluate its capacity to endure jumping stresses.
Comparisons were drawn between the heel bone structures of giant kangaroos and their modern counterparts.
The team estimated the strength of tendons necessary for the jumping force of a giant kangaroo and determined whether the heel bones could accommodate such tendons.
The findings suggest that the metatarsals of all giant kangaroos were adequate to withstand jumping pressures, and the heel bones were sufficiently large to support the width of the required jump tendons.
These results imply that all giant kangaroo species had the physical capability to jump.
Nevertheless, the researchers caution that giant kangaroos likely did not rely solely on hopping for locomotion, given their large body sizes, which would hinder long-distance movement.
They highlight that sporadic hopping is observed in many smaller species today, such as hopping rodents and smaller marsupials.
Some giant kangaroo species may have used short, quick jumps to evade predators. Thylacoleo.
“Thicker tendons offer increased safety but store less elastic energy,” said Dr. Katrina Jones, a researcher at the University of Bristol.
“This trait may have rendered giant kangaroo hoppers slower and less efficient, making them more suited for short distances rather than extensive travel.”
“Even so, hopping doesn’t need to be maximally energy-efficient to be advantageous. These animals likely leveraged their hopping ability to rapidly navigate uneven terrain or evade threats.”
University of Manchester researcher Dr. Robert Nudds remarks: “Our findings enhance the understanding that prehistoric Australian kangaroos exhibited greater ecological diversity than seen today, with some large species functioning as herbivores, akin to modern kangaroos, while others filled ecological niches as browsers, a category absent among today’s large kangaroos.”

Valar Atomics’ Ward 250 Reactor Under Construction
Daria Nagovitz/Valar Atomics
Despite contributing nearly one-fifth of the U.S. power generation, nuclear energy in the country has seen stagnation for decades. Factors such as regulatory challenges, public apprehension, and affordable energy sources have hindered growth, coupled with factory closure moratoriums and insufficient funding for new nuclear technologies. However, an increasing demand for power, especially from data centers, is reviving interest in nuclear energy. The Department of Energy is moving rapidly to rectify this delay with its reactor pilot program, aiming for a major milestone by mid-2026.
This initiative is part of the Department of Energy Strategy, which seeks to quadruple nuclear production by 2050. Eleven companies focused on advanced nuclear reactor technology have been chosen to participate, with expectations for at least three to reach criticality – a stable and self-sustaining nuclear fission state – by July 4, 2026.
“We intentionally set very ambitious deadlines,” stated Leslie Dewan, a nuclear engineer specializing in advanced reactor technology. “One of our pilot’s goals is to evaluate which concepts thrive under real-world conditions.”
The reactor designs under development range from molten salt and hot gas reactors to fast reactors, sodium-cooled systems, and pressurized water reactors. Notably, California-based Valar Atomics is regarded as a frontrunner, especially with its Ward 250 high-temperature gas reactor.
High-temperature gas reactors utilize small particles of uranium surrounded by carbon and ceramic coatings, transforming them into self-contained fuel units. This coating ensures that the particles remain intact even at extreme temperatures, creating a protective safety barrier to contain any radioactive materials.
Fuel particles are embedded within graphite blocks, which serve as the reactor core, featuring channels for helium gas circulation. The nuclear fission reaction generates heat that boils water, producing steam to power generators and generate electricity. The helium gas then returns to the reactor for reheating.
Valar broke ground on Ward 250 in September, marking it as the second company to initiate construction, following Texas-based Arlo Atomics which began in August. Valar has achieved the first low-temperature criticality, demonstrating a self-sustaining fission reaction under controlled conditions, offering valuable data to confirm core physics. “It’s not equivalent to constructing and operating your integrated test reactor at full power,” Dewan explained.
Texas-based Natura Resources is also developing molten salt reactors known for their inherent safety features, although they function differently. In these designs, uranium is dissolved in molten salt, heated by fission. A pump circulates this liquid salt to a heat exchanger, generating steam or driving a turbine. If overheating occurs, the molten salt expands and melts an emergency “freeze plug,” allowing the fuel to safely drain and preventing chain reactions.
“Molten salt reactors operate at atmospheric pressure, containing any accidents to the plant site,” emphasizes Dewan. “Even in a total power failure, the reactor can come to a safe stop without on-site operator intervention.”
Natura has not yet commenced construction but secured a permit from the Nuclear Regulatory Commission to build a 1-megawatt research reactor. Additionally, it has recently acquired Shepherd Power, which will enhance its supply chain and regulatory expertise to expedite its technology’s implementation. Dewan noted, “We have fostered a highly collaborative relationship with the NRC,” though she cautioned, “the challenges posed by molten salts, which are corrosive and radioactive at high temperatures, should not be underestimated.”
With the critical deadline approaching in about six months, Valar, Natura, and nine other companies in the pilot program must work at an exceptional pace to meet this goal. However, this is just one of many challenges that must be navigated.
“The true evaluations will center around whether we can safely power the reactor on and off, operate it for extended periods at design temperatures, and ensure that materials and fuel perform as anticipated. All of this must be reliably demonstrated to gain trust from the NRC and future clients,” Dewan concludes. “I see the 2026 date as the beginning of an intriguing data collection phase, far from the conclusion.”
The grand stone statues of Easter Island may have originated from diverse artistic and spiritual traditions, where multiple communities independently created their own massive carvings, rather than through a centralized effort led by a powerful ruler. This revelation aims to better identify the island’s primary quarries.
Easter Island, or Rapa Nui, located in the Pacific Ocean, is believed to have been settled by Polynesian navigators around 1200 AD.
Archaeological observations indicate that the Rapa Nui were not politically unified, prompting discussions on whether the numerous moai statues were produced under a centralized authority.
The island had only one quarry, Rano Raraku, that provided the volcanic rock utilized for the statue carvings.
Curl Lipo and his team at Binghamton University in New York employed drones and advanced mapping technology to develop the first 3D representation of the quarry, which holds many incomplete moai. Lipo noted that earlier studies yielded varying results regarding the number of moai remaining at the site.
Lipo and his associates documented 426 features representative of the moai at different completion stages, 341 grooves indicating the planned carving blocks, 133 carved cavities for removing the statues, and five bollards likely used for lowering the moai into position.
It was also noted that the quarry was divided into 30 distinct working areas, each functioning independently with various carving methods, according to Lipo.
The idea that small factions of workers may have relocated the moai statues, along with prior evidence of separate territories marked by groups at freshwater sources, hints that the statue carvings stemmed from community-level competition rather than centralized governance, Lipo explained.
“Monumentalism signifies a competitive display among peer communities instead of top-down mobilization,” he stated.
Historians continue to discuss the alleged decline of the Rapa Nui, with some contending that resource over-exploitation resulted in a severe social breakdown, while others challenge this narrative.
Lipo argues that the collapse theory presumes a centralized leadership pushed for monument construction, leading to deforestation and social disintegration. “However, if monuments are decentralized and arise from community competition rather than intentional expansion, then deforestation cannot be attributed to egotistical leadership,” Lipo comments.
Nevertheless, some researchers are skeptical about this perspective. Dale Simpson, from the University of Illinois at Urbana-Champaign, concurs there wasn’t a singular overarching chief as seen in other Polynesian regions such as Hawaii and Tonga; however, he suggests clans were not as isolated as proposed by Lipo and others, indicating there must have been collaboration among the groups.
“I think they’ve had a bit too much Kool-Aid and haven’t fully considered the limiting factors in a confined area like Rapa Nui, where stone is paramount. It’s not feasible to carve moai within a single clan without interaction and stone-sharing,” he notes.
Jo Ann Van Tilburg from the University of California, Los Angeles, mentioned that further investigations are in progress to ascertain how the Rapa Nui exploited Rano Raraku, asserting that the conclusions drawn by Lipo’s team appear “premature and overstated.”
Machu Picchu and the Science of the Incas: Peru
Immerse yourself in the vital ruins of the Inca civilization with two visits to Machu Picchu, and discover that the tale of the Incas encompasses much more than just one location.
Contemporary artificial intelligence (AI) models are vast, relying on energy-hungry server farms and operating on billions of parameters trained on extensive datasets.
Is this the only way forward? It seems not. One of the most exciting prospects for the future of machine intelligence began with something significantly smaller: the minute worm.
Inspired by Caenorhabditis elegans, a tiny creature measuring just a millimeter and possessing only 302 neurons, researchers have designed a “liquid neural network,” a radically different type of AI capable of learning, adapting, and reasoning on a single device.
“I wanted to understand human intelligence,” said Dr. Ramin Hassani, co-founder and CEO of Liquid AI, a pioneering company in this mini-revolution, as reported by BBC Science Focus. “However, we found that there was minimal information available about the human brain or even those of rats and monkeys.”
At that point, the most thoroughly mapped nervous system belonged to C. elegans, providing a starting point for Hassani and his team.
The appeal of C. elegans lay not in its behavior, but in its “neurodynamics,” or how its cells communicated with one another.
The neurons in this worm’s brain transmit information through analog signals rather than the sharp electrical spikes typical of larger animals. As nervous systems developed and organisms increased in size, spiking neurons became more efficient for information transmission over distances.
Nonetheless, the origins of human neural computation trace back to the analog realm.
For Hassani, this was an enlightening discovery. “Biology provides a unique lens to refine our possibilities,” he explained. “After billions of years of evolution, every viable method to create efficient algorithms has been considered.”
Instead of emulating the worm’s neurons one by one, Hassani and his collaborators aimed to capture their essence of flexibility, feedback, and adaptability.
“We’re not practicing biomimicry,” he emphasized. “We draw inspiration from nature, physics, and neuroscience to enhance artificial neural networks.”

What characterizes them as “liquid”?
Conventional neural networks, like those powering today’s chatbots and image generators, tend to be very static. Once trained, their internal connections are fixed and not easily altered through experience.
Liquid neural networks, however, offer a different approach. “They are a fluid that enhances adaptability,” said Hassani. “These systems can remain dynamic throughout computation.”
To illustrate, he referenced self-driving cars. When driving in rain, adjustments must be made even if visibility (or input data) becomes obscured. Thus, the system must adapt and be sufficiently flexible.
Traditional neural networks operate in a strictly unidirectional, deterministic fashion — the same input always results in the same output, and data flow is linear within the layer. While this is a simplified view, the point is clear.
Liquid neural networks function differently: neurons can influence one another bidirectionally, resulting in a more dynamic system. Consequently, these models behave stochastically. Providing the same input twice may yield slightly varied responses, akin to biological systems.

“Traditional networks take input, process it, and deliver results,” stated Hassani. “In contrast, liquid neural networks perform calculations while simultaneously adjusting their processing methods with each new input.”
The mathematics behind these networks is complex. Earlier versions were slow due to the reliance on intricate equations requiring sequential resolution before yielding an output.
In 2022, Hassani and his team published a study in Nature Machine Intelligence, introducing an approximate way to manage these equations without heavy computation.
This innovation significantly enhanced the liquid model’s speed and efficiency while preserving the biological adaptability that conventional AI systems often lack.
More compact, eco-friendly, and intelligent
This adaptability allows liquid models to store considerably more information within smaller infrastructures.
“Ultimately, what defines an AI system is its ability to process vast amounts of data and condense it into this algorithmic framework,” Hassani remarked.
“If your system is constrained by static parameters, your capabilities are limited. However, with dynamic flexibility, one can effectively encapsulate greater intelligence within the system.”
He referred to this as the “liquid method of calculation.” Consequently, models thousands of times smaller than today’s large language models can perform comparably or even exceed them in specific tasks.
Professor Peter Bentley, a computer scientist at University College London, specializing in biologically-inspired computing, noted that this transformation is vital: “AI is presently dominated by energy-intensive models relying on antiquated concepts of neuron network simulation.”
“Fewer neurons translate to a smaller model, which reduces computational demand and energy consumption. The capacity for ongoing learning is crucial, something current large models struggle to achieve.”
As Hassani stated, “You can essentially integrate one of our systems into your coffee machine.”
“If it can operate within the smallest computational unit, it can be hosted anywhere, opening up a vast array of opportunities.”

AI that fits in your pocket and on your face
Liquid AI is actively developing these systems for real-world application. One collaboration involves smart glasses that operate directly on users’ devices, while others are focused on self-driving cars and language translators functioning on smartphones.
Hassani, a regular glasses wearer, pointed out that although smart glasses sound appealing, users may not want every detail in their surroundings sent to a server for processing (consider bathroom breaks).
This is where Liquid Networks excel. They can operate on minimal hardware, allowing for local data processing, enhancing privacy, and reducing energy consumption.
This also promotes AI independence. “Humans don’t depend on one another for function,” Hassani explained. “Yet they communicate. I envision future devices that maintain this independence while being capable of sharing information.”
Hassani dubbed this evolution “physical AI,” referring to intelligence that extends beyond cloud settings to engage with the physical realm. Realizing this form of intelligence could make the sci-fi vision of robots a reality without needing constant internet access.
However, there are some limitations. Liquid systems only function with “time series” data, meaning they cannot process static images, which traditional AI excels at, but they require continuous data like video.
According to Bentley, this limitation is not as restrictive as it appears. “Time series data may sound limiting, but it’s quite the opposite. Most real-world data has a temporal component or evolves over time, encompassing video, audio, financial exchanges, robotic sensors, and much more.”
Hassani also acknowledged that these systems aren’t designed for groundbreaking scientific advancements, such as identifying new energy sources or treatments. This research domain will likely remain with larger models.
Yet, that isn’t the primary focus. Instead, this technology aims to render AI more efficient, interpretable, and human-like while adapting it to fit various real-world applications. And it all originated from a small worm quietly moving through the soil.
Artist’s interpretation of the pack Nanotyrannus assailing a young tyrannosaurus
Anthony Hutchings
Fossils previously thought to belong to a juvenile tyrannosaurus rex have been identified as a fully mature carnivore of a distinct species, resolving a long-standing debate in paleontology.
This controversy originated from a skull unearthed in the Hell Creek Formation in Montana during the 1940s, which was initially identified as gorgosaurus. It was later proposed to be a juvenile tyrannosaurus. In 1988, other researchers posited that the fossil represented an adult of a smaller related species, which they designated Nanotyrannus lansensis.
Since then, a number of additional fossils classified as Nanotyrannus have been discovered, although many paleontologists contend that they are merely tyrannosaurus juveniles.
Now, researchers have examined a complete skeleton for the first time, providing compelling evidence that Nanotyrannus is indeed a separate species.
The skeleton is among a pair of specimens known as “Dueling Dinosaurs,” found by private fossil hunters in 2006, which includes a triceratops and what was initially believed to be a juvenile T. rex buried approximately 67 million years ago.
It was only in 2020, when the fossil came into the possession of the North Carolina Museum of Natural Sciences, that paleontologists could conduct a thorough analysis of it.
“Upon receiving the specimen, we recognized it was extraordinary,” remarks Lindsey Zanno from the North Carolina Museum of Natural Science. “We had no inkling it would radically alter decades of research concerning the world’s most renowned dinosaur.”
Mr. Zanno collaborated with his colleagues, including James Naples, a postdoctoral researcher at Stony Brook University in New York. She had initially supported the juvenile tyrannosaurus theory but was compelled to reevaluate her stance based on the findings.
“Nanotyrannus displays unique nerve and sinus patterns, a greater number of teeth, larger hands, and shorter tails. These traits remain consistent as the species develops from juvenile to adult,” she notes.

Zanno and Napoli’s examination of the dinosaur’s limb bones confirmed that it was a fully mature specimen, approximately 20 years old, weighing around 700 kilograms and measuring about 5.5 meters in length. “This is roughly one-tenth the weight of an adult human and half the length of a tyrannosaurus,” Zanno explains.
Additionally, Zanno and Napoli reanalyzed 200 tyrannosaur fossils and concluded that another nearly complete skeleton, known as Jane from the Hell Creek Formation, is misclassified as a tyrannosaurid fossil. They propose that Jane is actually a new species within this genus, designated Nanotyrannus letaeus.
“Although we possess only one skeleton of N. Retheus, its anatomy suggests it was part of a larger species,” remarks Zanno. “The configuration of the palatal sinuses and the shape of the bone behind the eye are distinctive.”

Scott Parsons, a researcher at the South Carolina State Museum, asserts that this latest study clarifies the debate surrounding Nanotyrannus being its own genus and species.
“In my opinion, Nanotyrannus was among the most formidable dinosaur predators, and being pursued by one would be quite a terrifying experience,” Parsons remarks, noting its long legs and fearsome thumb claws.
“In essence, we can compare Nanotyrannus and tyrannosaurus to modern-day cheetahs and lions. While they shared a similar overall anatomy, they had distinct hunting strategies.”
Thomas Carr from Carthage College in Wisconsin has expressed that the new findings are “quite definitive” that the dueling dinosaur specimen represents an almost adult species, one that differs from tyrannosaurus.
Additionally, Holly Ballard from Oklahoma State University, who led the 2020 research, stated that there is “no contention” regarding the team’s conclusion that the fossil belonged to an individual nearing adult size.
However, neither Ballard nor Carr are fully convinced that the other fossil, Jane, constitutes a new species of Nanotyrannus. “Jane is still maturing and large,” emphasizes Ballard, suggesting it may be a new taxon rather than a juvenile tyrannosaurus. “We’re returning to the old debates,” Ballard laments.
“Moreover, in the Hell Creek Formation, if there are numerous small tyrannosaurs in circulation, where are the juvenile tyrannosaurus? ” Kerr questions, stating that it complicates the fossil record. “We simply haven’t uncovered enough tyrannosaurs to fully elucidate what was occurring during the growth phases of the tyrannosaurids in the Hell Creek Formation.”

Among the four fundamental forces in the universe, gravity often comes to mind when considering cosmic phenomena. This is quite logical, as gravity operates over vast distances, exerting its influence on massive objects, making it the most significant and far-reaching force. However, another essential force, known as electromagnetism, also plays a critical role in the study of space.
To begin with, all light is made up of electromagnetic radiation, which consists of oscillating electric and magnetic fields. This includes everything from radio waves to visible light and X-rays. Similar to Earth and the Sun, many celestial bodies are enveloped in magnetic fields. The Earth’s magnetic field serves as a shield against harmful radiation, while the solar magnetic field repels it. The generation of a magnetic field requires the movement of charged particles, such as protons and electrons. Consequently, a variety of objects, including entire galaxies, possess magnetic fields!
Researchers are aware that galaxies have magnetic fields, but it remains uncertain how various galaxies develop different magnetic intensities or how these fields influence their evolution over time. This investigation is further complicated by the fact that galaxies often exist in clusters. For instance, the Milky Way is surrounded by smaller galaxies known as satellites, which exert gravitational pull on each other and interfere with each other’s magnetic fields.
The research team explored how diverse environments in smaller galaxies affected the strength of their magnetic fields. They approached this by simulating the motion of materials within the galaxy as if they were liquids filled with striped particles. Two sets of simulations were conducted, the second of which also included the effects of high-energy particles known as cosmic rays.
In total, they simulated magnetic fields across 13 distinct scenarios, ranging from isolated galaxies with masses 10 billion times that of the Sun to those 10 trillion times greater, accompanied by up to 33 satellites. Each simulation commenced with galaxies exhibiting a magnetic field strength of 10-14 Gauss (g). For context, Earth’s magnetic field strength is about 0.3-0.6 g. The scenarios were evolved over 12 billion simulation years, allowing galaxies to interact, traverse space, and form stars, subsequently tracking the magnetic field strength in smaller galaxies.
Throughout the simulated timeline, the magnetic fields of all galaxies strengthened as star formation progressed. The birth of stars stirs the galactic matter, enhancing magnetic field strength and producing cosmic rays. Most galaxies concluded with magnetic fields ranging from 10-7 to 10-6 G, with larger galaxies typically achieving stronger fields. Interestingly, the researchers found that small galaxies passing in close proximity to larger companions exhibited stronger magnetic fields than equivalent isolated galaxies.
They monitored satellite galaxies over a series of simulations and discovered that, on average, magnetic field strength increased by 2-8 times as these galaxies approached their host. In extreme cases, the satellite’s magnetic field intensified by up to 15 times after nearing the host. In contrast, satellite galaxies that were more distant or had not yet approached their host did not show such significant increases in magnetic field strength.
The researchers interpret their findings to suggest that the more turbulent the interstellar medium (ISM) within a galaxy, the greater the strength of its magnetic field. Orbiting near a host galaxy tends to disturb the ISM of the satellite galaxy, rendering it more magnetic than a solitary small galaxy. Approaching a massive galaxy compresses the satellite, exposing it to magnetizing materials, and both interactions contribute to amplifying the magnetic field strength.
The team recommends that future studies utilize these results to inform radio and gamma-ray observations of galaxies, as these two segments of the electromagnetic spectrum can provide astronomers insights into the magnetic field properties of celestial bodies. They also caution that astronomers conducting simulations of isolated galaxies might yield skewed results since such a scenario does not accurately reflect the reality in which many galaxies are in proximity to companions.
For over a century, humble fruit flies have paved the way for many significant scientific breakthroughs. This small insect has helped researchers understand that X-rays can cause genetic mutations, with genes being passed from parents to children through chromosomes. A gene known as period helps our bodies maintain time; disruptions to this internal clock can lead to jet lag and increase the risk of neurological and metabolic diseases. These findings, along with nearly 90,000 other studies, are part of an essential online database called FlyBase, which researchers utilize daily to design new experiments more quickly. These tests could help explore the underlying causes of diseases and develop new treatments. Science builds on previous insights, and a comprehensive repository of past advances serves as a catalyst for future discoveries.
The website receives approximately 770,000 page views each month from scientists around the world, facilitating the development of personalized treatments in rare cases, modeling neurodegenerative diseases in humans, and identifying candidates for screening conditions such as Alzheimer’s disease. However, its vital resources are now facing potential layoffs that threaten its future and the ability to enhance research efficiency. This spring, the Trump administration withdrew grants used to maintain FlyBase as part of a $2.2 billion budget cut at Harvard University.
“I use FlyBase every day, and it’s incredibly essential,” said Celeste Berg, a professor of genomic sciences at the University of Washington. “What we know about human genes and how they function comes from model systems like Drosophila.” Humans share about 60% of our genes with the fruit fly known scientifically as Drosophila melanogaster. FlyBase’s current stability underscores how interconnected and interdependent research efforts are, highlighting how funding for one institution can have global repercussions. Over 4,000 labs utilize FlyBase.
Harvard received approximately $2 million annually in federal funds to maintain FlyBase, which constitutes a majority of the website’s overall operating budget. However, the University of New Mexico, Indiana University, and the University of Cambridge in the UK are partners and beneficiaries in assisting Harvard with FlyBase management. “This doesn’t just affect Harvard,” stated Brian Calvi, a biology professor at Indiana University who is part of the FlyBase management team. “The ripple effects extend to the international biomedical research community.”
According to Norbert Perimon, a professor of developmental biology at Harvard, the Faculty of Arts and Sciences temporarily funded FlyBase, but that support will cease in October. Earlier this month, a judge ordered the Trump administration to restore funding for Harvard researchers who lost the grant, but the funds have not yet been allocated to FlyBase, Perimon noted. The administration has promised to appeal decisions that could block funding flows. The White House did not respond to requests for comment, and the U.S. Department of Health and Human Services, which oversees the National Institutes of Health, declined to comment.
The Transmitter, a neuroscience news site, was the first to report the layoffs at FlyBase. The Harvard Crimson reported on the decision of Harvard’s School of Arts and Sciences not to extend provisional funding. Calvi mentioned that the FlyBase grant covered full or partial salaries for eight individuals at Harvard, three in Indiana, five in Cambridge, and one at the University of New Mexico. While Indiana and Cambridge have secured some funding to operate programs until next year, the New Mexico position ended in August.
Operating since 1992, FlyBase has been funded by the federal government for over three decades. It curates and summarizes research papers, organizes findings on specific genes, and catalogs information on genetically modified fruit flies to understand how particular genes lead to normal development. The fruit fly is the primary animal model for biomedical research as scientists have been able to map the brain to the genome, and it is relatively easy to handle. Berg, an avid FlyBase user and a professor at Genome Sciences, studies human development and how cells form organs. FlyBase allows researchers to search for and identify genes of interest for their experiments. Subsequently, they test how altering the expression of these genes affects cell placement. Thousands of fruit fly papers are added and summarized in FlyBase each year. Without FlyBase, Berg cautioned that researchers and clinicians could struggle to keep pace and miss crucial connections regarding specific genes.
Researchers from the Undiagnosed Disease Network employ FlyBase to determine whether pediatric genetic mutations contribute to rare, unknown diseases. They identify genetic mutations in patients and compare those with previous studies of those genes in flies. FlyBase also offers crowdfunding support on its website. “Given the importance of FlyBase to the broader U.S. and international scientific research community,” stated James Chisholm, spokesman for the Faculty of Arts at Harvard University. Two staff members from Harvard have already been laid off from FlyBase positions, with six more slated for layoffs in late September and early October, according to Perimon. “If we can’t retain key personnel, it’ll be very difficult to get people back with the knowledge necessary to keep the database operational,” Perimon remarked. “That would mark the end of FlyBase as we know it.”
Funding disruptions threaten plans to relocate FlyBase data to a new long-term home called the Genome Resource Alliance. The fruit fly, along with rats, mice, and worms, is one of several common “model organisms” used in labs to build the foundation for understanding human biology. The National Institutes of Health has allocated $5 million annually since 2017 to merge several databases, including FlyBase, WormBase, and Mouse Genome databases. Each of these contains information that human health researchers can cross-reference to study genes critical to human health more effectively. “If you’re studying human genes and need to access all existing information, you must visit all of these websites. I want one-stop shopping,” said Paul Sternberg, a professor of biology at the California Institute of Technology. The alliance’s budget expired on June 30, and Sternberg noted that they are awaiting a reclamation decision from the NIH. He mentioned that the funding disruption at FlyBase represents a new and unexpected challenge. “We need to move quickly, but with our staff and energy dwindling, we are at risk,” Sternberg expressed. “We can’t afford any additional obstacles.”
FlyBase had planned to merge with the Alliance in 2029. Now, Calvi and others are advocating for an accelerated merger before FlyBase’s financial runway disappears. Any donations the organization is soliciting are aimed at helping cover operational costs. “So far, we’ve raised under $100,000,” Calvi stated regarding the crowdfunding efforts. “We likely need a million.”

The 10 Pro is among the first devices to incorporate Qi2 wireless charging, allowing compatibility with a variety of magnetic accessories, including those designed for Apple’s MagSafe.
Under the hood lies Google’s latest Tensor G5 chip, offering approximately 35% improved speed over last year’s iteration, though it does not quite match the performance of Qualcomm’s top Android chips found in competing devices. The 10 Pro delivers a smooth user experience and performs well for gaming, although those seeking top-tier graphics may want to explore other options.
Boasting solid battery life, the Pixel enables a mix of 5G and WiFi usage lasting up to two days, with around 7 hours of active screen time. Most users will find they need to charge it every other day, but I managed to get through a heavy usage day in London, ending with approximately 25% battery remaining by midnight.

Zoom capabilities extend from 30x to 100x, utilizing a local generative AI model to recover lost details and sharpness during digital zooming. It generally performs well, although not flawlessly. AI-generated images may sometimes display inconsistencies in perspective or details. However, capturing predictable subjects like buildings, vehicles, and trees leads to solid results, making the 100x zoom surprisingly user-friendly.
When capturing people, the camera avoids using the Genai model, which might be the most suitable option. Yet, like all generative AI systems, it can occasionally struggle to produce coherent outputs, mirroring what often appears as alien-like scripts.
The camera application has integrated C2PA Content Credentials, documenting not only how images were taken but also whether generative AI was involved in their creation. Best Take functionality captures multiple images with a single press of the shutter button.
The 10 Pro also features AI camera coaching capabilities seen in the standard 10, providing users with guidance on scene composition and optimal shooting angles.
The camera comes loaded with entertaining photography and videography modes, solidifying the 10 Pro’s status as a leading contender in the market.

Verdict
The Pixel 10 Pro does not radically reinvent the smartphone with its enhancements but builds upon the successes of the Pixel 10, itself a strong contender this year. Yet it still elevates market-leading camera capabilities alongside advanced AI integration.
It offers reliable performance, solid battery life, and an attractive design, though avid gamers may prefer options with superior graphics. Google’s version of Android remains among the best, offering years of support for longevity.
Several new features in Gemini provide enhanced convenience with fewer gimmicks. Magic Cue is a valuable tool that saves time without being intrusive, though it could benefit from broader app integration.
The incorporation of generative AI into the camera app refines the zoom experience, albeit it does blur the distinction of traditional photography. Debates about authenticity in photography will undoubtedly arise as usefulness and novelty intersect.
The Pixel 10 Pro is among the finest compact smartphones available, showcasing just how sophisticated Google’s AI tools have become, surpassing both Apple and its other competitors.
Pros: Seven years of software updates, 5x optical zoom, 10x AI zoom, Magic Queue, impressive local AI features, Qi2 wireless charging with magnetic accessory support, solid battery life, excellent display, ergonomic size, quick fingerprint and face recognition, and a year of Google AI Pro subscription.
Cons: Relatively high price, does not match facial recognition safety, lacks best-in-class raw performance, and the absence of a physical SIM card slot in the US, with no major improvements over the standard Pixel 10.
The recent findings in Sulawesi, Indonesia, have revised the timeline for early human sea crossings, adding complexity to the puzzle of their creators.
Archaeologists have unearthed stone tools at a location in South Sulawesi, called Cario, dating back at least 104 million years. Given that Sulawesi is encircled by swift and deep waters, anyone who created these tools would have had to navigate the open ocean.
“This represents the earliest known evidence of early human presence in Sulawesi,” says Professor Adam Brumm from the Australian Center for Human Evolution Research at Griffith University, which co-directed the research. BBC Science Focus.
“It now seems evident that early hominins managed to cross the Wallace Line, leading to isolated populations on distant islands.”
The Wallace Line serves as a critical biogeographical boundary between mainland Asia and Wallacea Island. “For land mammals that don’t fly, such as those in Sulawesi, crossing from the edge of mainland Asia to the nearest Wallacea island would have been nearly impossible due to the vast distances and swift currents,” Brumm explained.
Earlier discoveries indicated that hominins arrived at nearby Flores Island approximately 102 million years ago, evolving into species like Homo floresiensis (nicknamed “The Hobbit” due to its stature) and Homo luzonensis.
However, as of now, no fossils have been discovered in Sulawesi, leaving the identity of the tool’s maker an enigma.
“We suspect it was an early Asian human species, possibly Homo erectus,” Brumm remarked. “I doubt they used boats for this journey. The colonization of the island likely occurred accidentally as they might have clung to logs or natural vegetation ‘rafts’ that were formed during tsunamis.”

If Homo erectus made it to Sulawesi more than a million years ago, they may have been carving out their own evolutionary niche.
“In Flores and Luzon, fossil discoveries indicate that hominins on these islands underwent evolutionary changes, leading to unique new species that are small and distinct,” noted Brumm. “Though we have yet to find human fossils in Sulawesi, the possibility of similar events occurring on the island cannot be ruled out.”
What’s next for Brumm and the team? “We’re continuing our excavations,” he stated. “Human fossils are incredibly rare, but millions of hominins have existed and perished over the last million years, so there might be preserved remains of these toolmakers out there.”
“We hope to discover a fossil—or two—with persistence (and a bit of luck), as finding one would be an extraordinary breakthrough, perhaps even a game changer.”
Adam Brumm is a professor of archaeology at Griffith University. His work has accumulated over 21 years of funding for research in Indonesia. His published studies include many in Nature, spanning topics from the discovery of new human fossils in Wallacea (the island region between Asia and Australia) to recent insights into human evolution.
A tiny disc, roughly the size of a nail, has the potential to ascend to high altitudes in sunlight while carrying sensors through some of the coldest and thinnest parts of the atmosphere. These swarms, flying higher than commercial aircraft and balloons, could reveal new insights regarding Earth’s evolving weather and climate.
These floating devices harness a phenomenon known as photophoresis. This was initially discovered over 150 years ago when chemist William Crookes invented a radiometer, a device with black and white feathers that spin when they are exposed to sunlight. The wings absorb light and release heat, increasing the momentum of nearby gas molecules. Due to the difference in temperature between the black and white sides of the wings, the black side emits more momentum, allowing the air to flow in one direction with sufficient force to turn the wings.
“We’ve embraced this lesser-known physics to develop applications that could benefit many people, enhancing our understanding of how weather and climate change unfolds over time.” Ben Schafer from Harvard University.
To create the levitating disc, Schafer and his team designed a device that spans 1 cm, composed of two sheets of aluminum oxide filled with microscale holes. When illuminated, the lower sheet, which contains alternating layers of chromium and aluminum oxide, heats up more than the top layer, similar to the black sides of the radiometer blades. This generates a directional airflow that moves upwards instead of sideways.
Under white LED and laser illumination — set to an intensity that mimics about 50% of natural sunlight — this upward force successfully lifted the device. This represents progress over previous solar-powered flyers, which required light intensity significantly brighter than sunlight. However, the tests were conducted under laboratory conditions with air pressure much lower than Earth’s surface pressure.
Fortunately, such low pressure conditions are common at higher altitudes, especially in the Mesosphere, which spans 50-85 km above the Earth. Researchers indicate that increasing the disc’s size to 3 centimeters could enable it to carry a 10-milligram payload to hard-to-reach research areas at altitudes of 75 km. Schafer has co-founded a startup, Rare Feed Technology, aiming to commercialize fleets of these high-flying devices for environmental monitoring and communications.
After sunset, computer modeling indicates that these discs could utilize the heat radiating from Earth’s surface to remain airborne. “If they can stay afloat during the night, that represents a significant advancement instead of simply descending and landing.” Igor Bargatin from the University of Pennsylvania, who is conducting similar research.
J1025+1402, one of three small red dot galaxies up to 2.5 billion light years apart
Digital Legacy Survey/d. Lang (Permieter Institute)
A new analysis shows that peculiar galaxies, once only identified in early cosmic formations, have surfaced more recently, raising intriguing questions about their origins.
Recent observations made by astronomers utilizing the James Webb Space Telescope (JWST) have revealed compact red entities from the universe’s first billion years, dubbed Little Red Dots (LRD). These were initially believed to be associated with phenomena in the early universe, like the formation of supermassive black holes at the cores of galaxies, including our own.
Xiaojing Lin from China’s Tsinghua University, along with her research team, has discovered LRD in a much younger universe, about 12 billion years post-Big Bang. “This finding demonstrates that the conditions fostering small red dots are not solely confined to the early universe,” states Lin.
The researchers employed a telescope based in New Mexico to analyze images captured during the Sloan Digital Sky Survey. They pinpointed three objects that appeared as LRD, but significantly, they were merely 2.5 billion light years apart.
“They meet all criteria for classification as small red dots,” remarks Xiaohui Fan from the University of Arizona. “I believe there’s no doubt regarding their similarity.”
Each LRD is estimated to be approximately one million times the mass of the Sun, with dimensions comparable to the solar system. One of these LRDs is nicknamed the “egg” due to its elongated structure. The team also identified a few other potential LRD candidates awaiting confirmation.
These findings are exhilarating, says Anthony Taylor from the University of Texas at Austin, as they provide unique insights into the characteristics of LRDs. These objects are faint enough that telescopes like the JWST and Hubble can analyze them significantly easier than their early universe counterparts, potentially unveiling their true nature.
“They’re much closer to us, making them appear much brighter,” adds Taylor.

A potential explanation for LRDs is that they signify the nascent phases of extraordinarily massive black holes maturing within the galaxy, possibly marking their initiation as they begin consuming matter voraciously.
It’s currently unclear whether local LRDs are dormant galaxies that have recently awakened or if they have just formed and are starting to consume significant amounts of material. “At this point, it is premature to discuss that aspect,” Taylor points out.
The team is eager to utilize Hubble and JWST to delve deeper into these local LRDs. “I have a proposal for Hubble pending approval,” Fan comments.
LRDs have the potential to exist not just in contemporary and ancient universes but throughout cosmic history. “They may have been lurking, camouflaged, amidst the cosmos,” Fan remarks. “People haven’t known what to look for.”
Low-density amorphous ice is one of the most prevalent solid materials in the universe and plays a crucial role in deciphering numerous well-known anomalies of liquid water. Despite its significance and discovery nearly 90 years ago, its structure remains a topic of debate. In a recent study, researchers from the University of London and Cambridge found that prior computer simulations of low-density amorphous ice were influenced by a disturbed structure where the ice was not entirely amorphous. Instead, it contained small crystals measuring 3 nm in width, slightly wider than a single DNA strand. In their experimental studies, actual samples of amorphous ice, which formed through different methods, were recrystallized (i.e., warmed up). They observed that the resulting crystal structure varied based on the method used to generate the amorphous ice. The researchers concluded that if the ice was completely disordered, it would not retain any imprint of its previous shape.

“We now have a solid understanding of what the most common ice structures in the universe look like at the atomic level,” states Dr. Michael Davis, a researcher at the University of London and Cambridge.
“This is significant because ice is involved in numerous cosmological processes, including planet formation, galaxy evolution, and the movement of matter throughout the universe.”
For their investigation, Dr. Davis and his colleagues utilized two computer models of water.
They simulated the freezing of water molecules in these virtual “cages” by cooling to -120 degrees Celsius (-184 degrees Fahrenheit) at various rates.
These different cooling rates affected the proportions of crystalline and amorphous ice produced.
The researchers determined that low-density amorphous ice, as evidenced by X-ray diffraction studies, appears to align with a mixture of up to 20% crystallinity and 80% amorphous structure (i.e., researchers fired X-rays at ice and analyzed the deflection patterns).
Using an alternative method, they created a large “box” filled with numerous small ice crystals tightly packed together.
The simulation then disordered the regions between the ice crystals, resulting in structures remarkably similar to those obtained from the initial approach of 25% crystalline ice.
In additional experimental efforts, scientists generated actual low-density amorphous ice samples through various methods, including deposits of water vapor onto extremely cold surfaces (mimicking how ice forms on interstellar dust) and from high-density amorphous ice (ice crushed at very low temperatures).
These amorphous ice samples were then gently heated to provide energy for the formation of crystals.
They noted variations in the structure of the ice depending on its origin, particularly regarding the arrangement of molecules in a hexagonal (6x) formation.
This provided indirect evidence that low-density amorphous ice contained crystalline constituents.
Should it be entirely disordered, the ice would lack any memory of its prior form.
The findings raised further inquiries about the nature of amorphous ice, such as whether crystal size varies based on the formation method, and whether truly amorphous ice is achievable.
“Water is essential to life, yet our understanding is still incomplete,” remarked Professor Michael Ryde from Cambridge University.
“Amorphous ice may be key to explaining many anomalies observed in water.”
“Ice holds potential as a high-performance material in space,” added Dr. Davis.
“It can shield spacecraft from radiation and supply fuel in the form of hydrogen and oxygen.”
“Understanding the various structures and properties is critical.”
Moreover, this research touches upon a speculative theory regarding the origins of life on Earth.
This theory posits that life’s building blocks were transported here on an icy comet, known as Panspermia.
“Our findings indicate that this ice might be a suboptimal transport medium for these biological molecules,” stated Dr. Davis.
“This is due to the reduced space available for partial embedding of these components in the crystal structure.”
“Nonetheless, the theory could still hold merit, as there are amorphous regions within the ice capable of storing and concealing life’s building blocks.”
“Ice on Earth captivates our curiosity due to our warm climate,” observed University College professor Christophe Salzmann from the University of London.
“You can see the intricate order of snowflakes in their symmetry.”
“Ice elsewhere in the universe has long been viewed as a frozen snapshot of liquid water: a disordered arrangement that is fixed in place. Our findings suggest that this perception is not entirely accurate.”
“Our results also prompt questions regarding the properties of amorphous materials in general.”
“Such materials are vital in advanced technologies.”
“For instance, fiberglass used for data transmission must be amorphous or disordered to function.”
“If these materials contain small crystals, their performance can potentially be enhanced by removing them.”
The findings were documented in a paper published today in the journal Physical Review B.

Long-term conclusive results from US-based experiments have emerged. The latest release on Tuesday highlights a tiny particle behaving unexpectedly, which is still positive news for our understanding of Physics Laws.
“This experiment represents a remarkable achievement in precision,” noted Toba Holmes, an experimental physicist at the University of Tennessee Knoxville, who is not affiliated with the collaboration.
The enigmatic particles known as Muons are heavier than electrons. They exhibit a wobbling motion akin to a spinning top when subjected to a magnetic field, and scientists are scrutinizing this motion to determine its compliance with the well-established physics framework known as the standard model.
Findings from the 1960s and 1970s suggested everything was functioning as expected. However, investigations at Brookhaven National Laboratory in the late 1990s and early 2000s yielded unexpected results.
Decades later, an international coalition of scientists opted to revisit the experiment with enhanced accuracy. The team navigated Muons around magnetic, ring-shaped tracks akin to those used in the initial Brookhaven studies, and recorded the wobble signals at Fermilab National Accelerator Laboratory near Chicago.
The outcomes from the initial two sets published in 2021 and 2023 appear to affirm the odd behavior of Muons, encouraging theoretical physicists to reconsider the standard model alongside new metrics.
Recently, the team finalized the experiment and published Muon wobble measurements that align with their earlier findings, utilizing more than double the data collected in 2023.
Nevertheless, this does not finalize the fundamental understanding of what underpins the universe. As Muons travel along their paths, other researchers have devised methods to better harmonize standard models with observed behaviors, leveraging the power of supercomputers.
Further investigation is essential as researchers collaborate, and upcoming experiments will encourage future studies that assess Muon wobble. Scientists are also examining the latest Muon data for insights into other mysterious entities like dark matter.
“This measurement will serve as a benchmark for years to follow,” remarked Marco Incagli from the Italian National Institute of Nuclear Physics.
In their pursuit of Muons, scientists aim to unravel fundamental questions that have long intrigued physicists, as noted by Peter Winter from the Argonne National Laboratory.
“Isn’t it something we all wish to understand—how the universe operates?” Winter questioned.
Lead by a team of paleontologists from the National Museum of Scotland, this specimen is recognized as the first and most complete dinosaur skeleton discovered in Scotland to date.

The newly identified specimen originates from the mid-Jurassic period, approximately 166 million years ago.
“Dinosaurs from the Triassic and Early Jurassic were typically small, bipedal, and carnivorous or omnivorous. However, by the late Jurassic, a remarkable diversification occurred, leading to the emergence of some of the largest terrestrial vertebrates to ever walk the Earth,” stated Dr. Elsa Pansilolli, a paleontologist and her colleagues at the National Museum of Scotland.
“This significant diversification in dinosaur species appears to have primarily occurred during the mid-Jurassic period, positioning these dinosaurs as key elements for understanding the drivers behind this rapid evolution.”
“Unfortunately, central Jurassic dinosaur fossils are exceedingly rare and underrepresented globally,” they added.
“Consequently, the early evolutionary history and major diversification of many dinosaur groups remain largely unknown.”
“Thus, new dinosaur findings from the central Jurassic are critical for unwinding the development of ecosystems dominated by dinosaurs.”

Partial dinosaur skeletons were initially discovered in 1973, but the collection was only completed in 2018.
“The specimen comprises numerous bones and fragments that seem to originate from a single bedding plane within an area measuring approximately 60 cm x 40 cm,” remarked the paleontologist.
The skeleton was uncovered in the Kilmalag Formation, located north of the village of Ergol on the Isle of Skye.
This representation includes Scotland’s most comprehensive fossils, with its initial discovery preceding the earliest reported dinosaur fossils from Skye.
“The central Jurassic in Scotland is becoming more representative of fossil finds from the Kilmalag Formation, increasing its global significance in understanding this period of tetrapod evolution,” the researchers indicated.
“Despite being fragmented, it remains the most intact dinosaur specimen known from Scotland, including partial ilium, nerve arches, rib parts, and other key elements.”
The dinosaurs from the Middle Jurassic are likely Ornithischian Dinosaurs, known as Ornithopoda.
“If the specimen is confirmed to represent Ornithischian, as suggested by the partial iliac bone and histological sections, it signifies a geologically recent event in Scotland, originating from the Kilmalag Formation,” the scientist noted.
The team’s study has been published in the journal Earth and Environmental Science Transactions of the Royal Society of Edinburgh.

Extinct Kangaroos from the genus Protemnodon A recent study by paleontologists from the University of Adelaide, Queensland Museum, and Monash University discovered that these creatures were not adventurous wanderers traversing the plains, but rather homebodies that remained close to their habitats throughout their lives. This finding aligns with behaviors observed in modern kangaroo species, yet it was surprising to the researchers.

Among large herbivorous mammals, greater body sizes are often associated with broader foraging ranges; however, it remains uncertain if this trend applies to extinct Australian megafauna.
In this study, paleontologist Christopher Laurikainen Gaete and colleagues investigated protemnodon fossils found in the Etna Cave, located north of Rockhampton in Central Queensland, Australia.
They examined strontium isotopes from kangaroo teeth, revealing matches only with local limestone rather than distant rock formations.
“The strontium isotopes in the fossilized teeth indicate the geology of the region where food was sourced,” they noted.
The findings suggest that Protemnodon had a significantly smaller foraging range than anticipated for its size, which is estimated at up to 170 kilograms.
Prior research indicates that Protemnodon likely lacked the capacity for long-distance travel due to its large size, thereby restricting its movement.
Additionally, this new study suggests that the stable, lush rainforest habitat provided sufficient food sources, negating the need for Protemnodon to wander far.
When climate change and increasing aridity disrupted this rainforest ecosystem about 280,000 years ago, the reduced foraging area may have left Protemnodon unable to find sufficient food, ultimately leading to the local extinction of these giant kangaroos.
Further investigations are needed to ascertain whether the limited range of Australia’s gigantic marsupials is a widespread pattern attributable to habitat rather than body size.
“We utilized data from contemporary kangaroos to predict a much broader foraging range for these giant extinct kangaroos,” explained Laurikainen Gaete.
“We were astonished to find they didn’t roam at all.”
“These innovative isotopic techniques have significantly advanced our field,” remarked Dr. Scott Hocknall, a senior scientist and curator at the Queensland Museum and paleontologist at Monash University.
“Think of it as an ancient GPS tracker. Fossils allow us to monitor individual movement, dietary habits, social interactions, and causes of death.”
“The ongoing debate regarding the extinction of Australia’s megafauna has persisted for decades, and now we can analyze it from an individual and species-specific standpoint,” stated Professor Anthony Doset, a paleontologist at the University of Wollongong.
“These precise methodologies enable us to examine each site and individual, facilitating more accurate extinction models.”
Researchers are currently planning to apply these methods to reconstruct the past behaviors and diets of MT ETNA and other extinct kangaroo species in the Capricorn Cave region.
“Many of the kangaroo species on Kangaroo Island, such as those found in Capricorn Caves, include tree kangaroos, pademelons, and rock wallabies, with descendants inhabiting the wet tropics and Papua New Guinea,” noted Professor Doset.
“We will employ these same techniques to explore how these surviving kangaroo species adapted to the environmental changes that contributed to the massive extinctions.”
The study will be published in the journal PLOS 1.

Private equity giant Blackstone is evaluating Tiktok’s potential as the April 5 deadline set by President Trump for Chinese-owned apps approaches, which could result in US bans under federal law.
Investing in Tiktok would give Blackstone the chance to acquire one of the world’s most popular social media platforms, with over 170 million American users. It remains uncertain whether the investments, likely to be part of Blackstone’s typical portfolio, will proceed, as other investors are also considering apps owned by China’s Internet giant integration.
Should the investment go through, it could sway President Trump’s favor. Congress passed a law last year mandating the sale of the app due to national security concerns related to Chinese ownership.
Trump extended the deadline for the deal in January and hinted at a possible extension if an agreement is not reached next week. He also suggested easing tariffs on China in exchange for support for the deal.
Blackstone’s interest adds to Tiktok’s tumultuous history in the United States. The video app has faced political pressure to shut down domestically multiple times. In January, the app was temporarily disabled in the US for about 12 hours before coming back online. A Blackstone spokesperson declined to comment on the speculation. Both Tiktok and the White House did not respond to requests for comments. Reuters previously reported on Blackstone’s interest.
As the April 5th deadline approaches, discussions about potential suitors for Tiktok have escalated. Trump has been approached by various parties pitching their ideas, with his interest in different arrangements potentially changing quickly, according to sources close to the discussions.
The most probable scenario is a deal where current US investors in ByteDance transition their stakes into a new independent, global Tiktok company, with additional US investors like Blackstone brought in to reduce Chinese ownership. This setup would allow Tiktok to continue operating without a complete sale, as mandated by law.
“There are multiple options that we can discuss with President Trump and his team that would allow the company to keep operating. There may be some changes in control, but it doesn’t necessarily mean a full sale,” a source said.
Blackstone, a firm managing over $1 trillion, typically engages in large-scale deals and invests in a diverse range of companies like Rover, Spanx, and Jersey Mike’s.
Private equity firm chief Stephen Schwartzman has ties to China as a Republican mega-donor and Trump supporter, which could bring significant business advantages.
Current top investors in ByteDance include Susquehanna and Atlantic General, who are likely to increase their interest in Tiktok’s shares as part of any new deal. Oracle, which hosts Tiktok’s data, is also involved in consultations, according to sources.
Artificial intelligence is trained on human-created content, known as actual intelligence. To train AI to write fiction, novels are used, while job descriptions are used to train AI for writing job specifications. However, a problem arises from this approach. Despite efforts to eliminate biases, humans inherently possess biases, and AI trained on human-created content may adopt these biases. Overcoming bias is a significant challenge for AI.
“Bias is prevalent in hiring and stems from the existing biases in most human-run recruitment processes,” explains Kevin Fitzgerald, managing director of UK-based employment management platform Employment Hero. The platform utilizes AI to streamline recruitment processes and minimize bias. “The biases present in the recruitment team are embedded in the process itself.”
One way AI addresses bias is through tools like SmartMatch offered by Employment Hero. By focusing on candidates’ skills and abilities while omitting demographic information such as gender and age, biases can be reduced. This contrasts with traditional methods like LinkedIn and CVs, which may unintentionally reveal personal details.

Another concern is how AI processes information compared to humans. While humans can understand nuances and subtleties, AI may lack this capability and rely on keyword matching. To address this, tools like SmartMatch evaluate a candidate’s entire profile to provide a holistic view and avoid missed opportunities due to lack of nuance.
SmartMatch not only assists in matching candidates with suitable roles but also helps small businesses understand their specific hiring needs. By analyzing previous hires and predicting future staffing requirements, SmartMatch offers a comprehensive approach to recruitment.

A new genus and species of enantiornithine bird in the family Bohaiornithidae has been identified from a nearly complete, articulated skeleton preserved with feather marks found in northeastern China.
holotype of Neobohyornis ramadongensis. Image credit: Shen others., doi: 10.1038/s41598-024-82869-8.
Enantiornis, or “opposite bird”, is named for the feature of the shoulder joint that is “opposite” to that seen in modern birds.
These birds had toothed and clawed wings and occupied a variety of ecological niches comparable to neonis.
Once the most diverse group of birds, they became extinct 66 million years ago due to a meteorite impact that wiped out most of the dinosaurs.
The newly identified enantiornithine species lived during the Cretaceous period, about 119 million years ago.
with scientific name Neobohyornis ramadongensisthis bird belonged to an early enantiornithine family called . Bohiornithidae.
“The most diverse bird group of the Mesozoic Era was the enantiornithids,” said field museum paleontologist Dr. Jinmai O'Connor and colleagues.
“More than 100 named genera have been described to date, and fossils referable to this group of primarily arboreal birds have been described from nearly every continent, making it the largest known Mesozoic bird species. It accounts for half of the animals.
“Although restricted to smaller body sizes during the Early Cretaceous, by the Late Cretaceous Enantiornis had achieved a considerable size range and occupied diverse ecological niches.”
“The most abundant enantiornithine fossils come from deposits recording the Early Cretaceous Jehol biota in northeastern China, and the known Mesozoic bird diversity (130 to 100 million years) 20 million years ago).
“Bohaiornithids are characterized by a unique robust tooth morphology,” the researchers added.
“The tooth is apically pinched, gently curved apically, and mesiodistally robust near the base.”
“The most rostral teeth are typically smaller in size compared to the rest of the dentition.”
“Like most enantiornithids, Bohaiornithids are arboreal, based on the morphology of the foot, with the toe phalanges extending distally within each digit, ending in a highly recurved ungulate. It is highly likely that
“But compared to other species, their claws were proportionately larger and more curved.”
“The largest member of the clade (bohaiornis) may have approached a similar size to the small extant ascites (200 g). ”
“The largest known bohaiornithid is 167% the size of the smallest specimen yet reported, an unnamed juvenile.”
fossilized skeleton Neobohyornis ramadongensis It was discovered in the Jiufutang Formation near Ramadong, Liaoning Province, China.
“The fossil preserves a ring of feather traces from the caudal margin of the nostril to the underside of the neck, the shoulder and pelvic area, the lower leg feathers, the remige, and a pair of rachis-dominated tail feathers. “,” the paleontologists said.
According to the researchers, Neobohyornis ramadongensis It is estimated to weigh around 50g.
“in contrast, Neobohyornis ramadongensisand all other Bohaiornithids are estimated to have weighed more than 100 g,” they said.
The discovery of Neobohyornis ramadongensis Therefore, the body size range and diversity of Bohaiornithidae increases significantly. ”
“This suggests greater ecological diversity, but no direct evidence exists for the diet or ecological niche of this clade at this time.”
Neobohyornis ramadongensis It also preserves new information about the plumage of Bohaiornithidae birds.
This fossil, along with another specimen, shows that the primary feathers of Bohyornithids were about twice as long as the humerus, had rounded wing edges, and, like most other Early Cretaceous enantiornithids, had broad wings. It shows that he had.
“The new specimen represents a new species that contributes to the considerable recognized diversity of enantiornithines in the Bohaiornithidae of the Jiufudang Formation, especially with regard to body size,” the scientists said.
“This specimen reflects the reduced pinky and big fingers that evolved within this lineage as it evolved more sophisticated flight abilities in parallel with other enantiornithid lineages such as Myrididae. It highlights skeletal adaptations such as the possibility of increased sacral vertebrae.”
“The new specimen preserves the most well-known feathers of the Bohaiornithids, and it is possible that this clade had widespread rachis-centered tail feathers, as well as lower leg feathers. It shows that it has a high sex and there were no feathers on the podium.”

Who holds the record for the world’s tallest snowman? Surprisingly, it’s a snow woman. Back in 2008, the residents of Bethel, Maine, USA built Olympia the Snow Woman, standing at an impressive height of 37.21 meters (just over 122 feet).
Science played a crucial role in creating this monumental snowman. The right type of snow is essential for such a feat. Snow that accumulates in temperatures between 0 to 2 °C (32 to 35 °F) is ideal. This temperature range allows free water to act as glue between the ice crystals, helping maintain the snowman’s shape. Snow with a moisture content of 3-8% is perfect, while anything over 15% leads to slushiness.
But why bother building a snowman if it’s just going to melt? The first known depiction of a snowman dates back to a Dutch prayer book from 1380. Unlike the cheery snowmen we’re familiar with like Frosty and Olaf, this medieval illustration shows a snowman being melted by fire, conveying a different message.

Historian Robert Eckstein notes that snow was a form of artistic expression for people. Building snowmen was a source of entertainment and a way to creatively express oneself, much like selfies are today. People could create their own snow sculptures for fun or display. Even the renowned Michelangelo was once asked to construct a giant snowman for a clown in 1494.
Building snowmen also served as a unique method for people to express their opinions on political matters. In 1511, residents of Brussels crafted over 200 snowy scenes, many of which were satirical representations of politicians and public figures. Snow became a medium for sharing messages.

WWhether it’s catching up with colleagues or gathering to set New Year’s resolutions, many of us will be reconnecting via Zoom, Teams, or Google Meet on Monday morning. But while such platforms have revolutionized flexible remote work in recent years, scientists are increasingly realizing that they can have a negative impact on people’s energy levels and self-esteem. So how can you have a healthier relationship with video conferencing in 2025?
Psychologists coined the term relatively early in the pandemic. “Zoom fatigue” Learn about the physical and psychological fatigue that can result from using video conferencing platforms such as Zoom for long periods of time. We found that people who had longer meetings using technology or who had a negative attitude toward meetings were more likely to feel: They made me even more exhausted..
Further research has found that the use of the self-view feature, which allows you to control whether your video is shown on screen during a meeting, is associated with increased fatigue levels. “We also found a gender effect, with women reporting more Zoom fatigue than men,” said Dr. Anna Carolina Queiroz, associate professor of interactive media at the University of Miami in Florida, who has been involved in these studies. says.
An insight from her the study People tend to feel more connected to others through frequent, short, and small group video calls rather than long meetings with many participants. This is likely because it takes longer to maintain nonverbal communication cues, such as eye contact, with many people. A lot of mental effort.
Those who are more sensitive to these communication cues may be more negatively affected, which may explain why women, who often feel greater pressure to present a positive image of themselves on video, tend to feel more fatigued. That could help explain things, Queiroz said.
She suggests keeping online meetings as short and small as possible and taking breaks between meetings to improve cognitive performance.
another the study This suggests that people who spend a lot of time video conferencing may become more conscious of their appearance and may be more likely to report greater dissatisfaction with it. Some people become so preoccupied with perceived flaws that they become anxious about attending gatherings and seek cosmetic surgery to change their appearance.
Dr. George Klompouzos, a professor of dermatology at Brown University and a practicing dermatologist, says, “If you’re worried about imperfections, continued exposure to images of yourself in virtual meetings tends to make those problems worse.” “There is,” he says. “Zoom dysmorphia is at least as common as body dysmorphia, which is a painful or disabling form of perceived or real defect that affects about 2% of the general population.” I’m thinking about it.
Dr. Cemre Turk, a dermatologist and postdoctoral fellow at Massachusetts General Hospital in Boston, US, says that Zoom dysmorphia is very likely to cause an increase in body dysmorphia, which can be devastating to people’s work and personal lives. It said it was important to identify it because it could have an impact. , in collaboration with Kroumpouzos. screening questionnaire It could help identify and treat more such patients.
Even if frequent video conferencing didn’t motivate people to seek facial surgery or “tweaks,” something else did. Recent research suggests It can unconsciously shape purchasing decisions in other ways.
Li Huang, Ph.D., an assistant professor of marketing at Hofstra University in New York, and his colleagues used a combination of eye tracking and surveys to determine how people liked different products after participating in different types of Zoom video calls and in-person meetings. Interest was assessed. Researchers found that video calls increased people’s anxiety about being negatively evaluated by others, whether they realized it or not, and increased their interest in self-help products in the aftermath of the call. It turns out.
Although it may sound negative, “this could actually have some positive consequences,” Huang said. “People are increasingly interested in self-improvement products, but this is not limited to body improvement products such as facial creams, but more general forms such as signing up for a LinkedIn learning course or participating in a health check-up. It also includes self-improvement.
“Most of the time, we are unaware that these types of virtual interactions are affecting our psychological well-being, and we may end up making impulse purchases online without knowing why. By learning about these findings, people can try to reduce these types of impacts.”
For example, the study found that this effect was reduced if study participants were able to turn off their webcams or use ring lights to emphasize their appearance during calls.
Switching to “Speaker View” instead of “Gallery View” and turning off “Self View” can also help, and asking participants to write about their strengths and characteristics after the call can also boost self-esteem. It was helpful.
Another factor that may help reduce the negative effects of video calls is zoom the background Selected. Dr. Heng Chan of Nanyang Technological University in Singapore and his colleagues assessed how tired people felt after video conferencing and found that virtual video backgrounds, such as videos of swaying palm trees or waves crashing on a beach, were associated with feelings of fatigue. I discovered that it does. There is a feeling of fatigue at the highest level, followed by a blurred background. Perhaps this is because the brain is forced to work harder by constantly reacting to new visual information, including the occasional intrusion of unblurred objects, Chan said.
People looking at static virtual backgrounds felt the least fatigued, especially if it was a nature-based image, and another study suggests it may have a calming effect. Masu.
The study didn’t assess the impact of people using real-world backgrounds, but Zhang, who uses backgrounds of trees and mountains for his video calls, said still images were still better. I think it might be better. “If you have your own office, that’s fine, but if you’re in a coffee shop or working outside, there’s a chance that people will be walking behind you or something else will happen that will distract your brain. Yes,” says Chan. “Even if you have your own office, you might be distracted by your personal belongings or worried about what others think of you.”
Huang hopes that in addition to using insights like this to help individuals protect themselves from the negative emotional impact of video conferencing, platforms will also take steps to foster a more positive user experience. I’m here. For example, instead of offering standard beauty filters, you can allow users to adjust lighting and background blur to improve their look more seriously.
“Increasing autonomy over privacy settings, such as controlling who can see and when, could also help reduce the pressure on users to always be visible to many people in meetings,” she said. I say.
Platforms could also consider leveraging artificial intelligence to detect signs of emotional distress in people’s voices and facial expressions, offering features such as discreet breaks and mindfulness exercises to help manage emotions. says Huang.

I think AI is going to change everything,” San Francisco Ballet Artistic Director Tamara Rojo told me earlier this year. “We just don’t know how.” Artificial intelligence’s influence on the creative industries can already be seen everywhere in film, television and music, but dance relies heavily on live bodies performing in front of an audience. As a format, it appears to be somewhat isolated. However, this week, choreographers Ao Nakamura and Esteban Lecoq, collectively known as AΦEis launching Lilith.Aeon, what is billed as the world’s first AI-driven dance production. The performer, Lilith, is an AI co-created with Mr. Nakamura and Mr. Lecoq. “She” appears in an LED cube, which the audience moves around, and their movements trigger Lilith’s dance.
Nakamura and Lecoq argue that they are interested in enhancing storytelling, rather than pursuing cutting-edge technology for its own sake. Working as dancers with the theater company Punchdrunk opened their eyes to the idea of immersive experiences, which led to virtual reality (VR), augmented reality (AR), and now AI. Their question is always, “How can we make this technology happen?” But it’s not like robots are going to take over the world.
Lilith.Aeon’s story is inspired by transhumanism (using technology to evolve beyond human limitations) and began as a script written by an AI bot. Nakamura and Lecoq provided all of their research to AI, including images, audiobooks, and discussions. “And we were able to interact with the AI, collaborate with it, and co-create the work together.” The two created a “dictionary-like” step that Lilith was trained on; The AI continued to generate new “words” of its own. They were excited when Lilith did something they never expected, but the choreography is still tailored to their aesthetic. “It’s not random,” Lecoq says. “I’m not interested in looking at things like screensavers.”

You can’t talk about AI in dance without talking about Wayne McGregor. Always at the forefront when it comes to technology, I first started researching AI 20 years ago. McGregor developed it in collaboration with Google. Somais a choreographic tool trained on his 25-year archive of work that can analyze thousands of hours of video and derive real-time suggestions, just as dancers improvise in the studio. He used AISOMA to generate a new version of his 2017 work autobiography It varies from performance to performance. His latest project, which opens next year, is on another earthdeveloped with Professor Geoffrey Shaw in Hong Kong, uses a 360-degree screen with sensing technology to allow viewers to build their own experiences.
choreographer alexander whitley We are also developing ways to use AI to integrate audiences into our work. The VR version of The Rite of Spring works on using audience movements as triggers for avatars trained on Whitley’s database of choreography. This technology allows amateur spectators to make their movements more artistic, and even allows them to arrange their movements to the music, like a dance version of Autotune.
Technology is developing rapidly. A type of motion capture that was once the province of Hollywood studios is now accessible through an app on your phone (try it) Move.ai), much of the progress is being driven by the gaming industry. However, there are some pitfalls that are worth looking into. Video game performers, including motion capture actors, impressive In the US, due to concerns about being replaced by AI (similar to the actors’ strike in 2023). Dancers are already being recorded by companies that build motion banks (“We’ve done about a million projects that require motion capture, like someone spinning on their head,” McGregor says). And the issue of rights and royalties when using dancers’ movements (and expertise) to train AI is a big one. McGregor said outright acquisitions were common in motion capture deals in the past. “We didn’t understand how the technology would be applied in the future.” He is currently working with Arts Council England on intellectual property (IP), motion data and “ethical AI”. I would like to take action. If done well, this could become a new source of income for dancers. “Coding choreo makes coin,” quotes Jonzi D from a hip-hop show. frayedfeaturing AI-generated dancing avatars.
But what if you want to create coins for others? Dancing is an ever-changing art form, passed down through dance floors, studios, and now social media, and where ideas originate. It can be difficult to know or prove what happened. You can copyright a dance piece, but you can’t copyright a step, as dancers who tried to sue the makers of the video game Fortnite discovered. Files can be copyrighted. Nigerian choreographer Kudus Onyikeku uses AI to recognize and classify movements to build a dance databank and protect intellectual property, especially of black artists, which has often been exploited in the past. We are conducting research.
Artists who are serious about AI are partnering with big companies like Nvidia, Amazon, and Dell. They get technology, and in return companies get ideas, accolades, and importantly, data. Are they selling their souls or just pragmatism? Potentially, it affects both directions. “We don’t want to be an adopter of technology,” McGregor says. “You want to be part of the conversation from the beginning and be the voice. If you want to stay ahead of the curve, otherwise you’ll just be servicing the technology.” Often developing tools Commercial funding is the only way to do so, and some tools have the potential to democratize dance and demystify it. Whitley is working on software that can be used in education, allowing students with no dance knowledge to create their own choreography on screen.

“I think humans and AI can do great things together,” says Jonzi D. But he also notices that most of the AI-generated content he sees has a certain similar look. “It comes down to how creatively you can use it.” Lecoq agrees that if everything is trained on the same content, everything will look the same. Art will undermine itself. “It would be lazy not to push the boundaries further,” he says. AI is not a shortcut when developing technology as we go along, as AΦE does. “It’s a long cut. It’s a very difficult and lonely process.”
Rojo thinks of several useful applications for AI in dance. For example, algorithms that can solve the headache of recasting a ballet when someone is injured can calculate who is available, who knows the role, etc. in seconds. Less useful, she says, “is if the composers were changed, the set and lighting designers were changed,” and the choreography patterns were created by artificial intelligence. “And it’s not outside the realm of possibility.”
However, computer intrusion into creativity is nothing new. “Computers are the future of dance,’’ said the choreographer. Merce Cunningham Back in 1995, he had already been working on the LifeForms program for six years, manipulating avatars on screen and transmitting the results to dancers. The intention was to shed the dancers’ natural habit of one movement instinctively leading to another and find something new, which choreographers have always tried.
So is that good or bad for the industry? “I try to avoid the binary of technology as either a savior or a destroyer,” Whitley says. There will inevitably be disruptive effects on the industry, “but there are also some really exciting possibilities that come with it.” Not all dancers will lose their jobs. “I’m not worried about turnover at all,” McGregor says. For him, it’s about using technology to better understand the complexities of the human body. “And we are far from building a version that somehow replicates the brilliance of the human body. Human virtuosity and ingenuity are what we are most often associated with.”
Watching dance is also about getting to know the limits of the human body and seeing it reach its limits. There’s no point in having an avatar that can do anything. Mr McGregor said: “There is no danger in the digital world.” But even if there is AI intervention in the choreography, “when performed by living, breathing humans, it becomes meaningful and tangible.” says Whitley. “Certainly, live performance cannot replace digital experiences,” Nakamura says. She’s not interested in seeing real people replicated on screen (“What do you mean?”), but with Lilith.Aeon, she wants to create something that couldn’t exist otherwise. I’m thinking. But despite the fact that AΦE is pioneering the latest in artificial intelligence, Lecoq claims that they are not very interested in technology. “The best technology that I like is the washing machine and the microwave.”
Predicted trajectory of asteroid CAQTDL2 over the Philippines
Catalina Sky Survey/ESA
Astronomers have discovered that an asteroid is on its way to collide with Earth at thousands of kilometers per hour, likely somewhere east of the Philippines, over the ocean. Fortunately, this relatively small object won’t pose any harm and will simply burn up in the atmosphere in a fireball.
The asteroid, estimated to be about one meter in diameter, was a NASA-funded Catalina Sky Survey. The asteroid has been named CAQTDL2 and is scheduled to impact Earth at approximately 16:45 GMT, 17:45 London time, 12:45 New York time, and at approximately 00:45 local time at the impact site in the Philippines.
It is currently estimated that CAQTDL2 will impact at a speed of 17.6 kilometers per second, or 63,360 kilometers per hour. Alan Fitzsimmons That’s average for such an object, says a researcher at Queen’s University in Belfast, UK. “Don’t be fooled by Hollywood movies where you see something screaming into the sky and you have time to run out the house, grab your cat, hop in your car and drive somewhere. You don’t have time for that,” he says.
Fortunately, no such evacuation is necessary. Although the impact would be dramatic and could shine as brightly as the moon in the night sky, it poses no danger to people on the ground. “An object this small can’t do any damage on the ground because it’s protected by the Earth’s atmosphere,” Fitzsimmons says. “It would just burn up harmlessly and then explode in a very impressive fireball.”
Asteroid CAQTDL2 can be seen moving across the sky in a purple circle.
Catalina Sky Survey
Fitzsimmons said two to three objects this size hit Earth each year, and early detection is becoming more common – astronomers first spotted a near-Earth asteroid before it fell to Earth in 2008. CAQTDL2 is the ninth asteroid to be accurately predicted to hit Earth.
“The really good thing about this is that our survey telescopes are now good enough to detect these objects as they approach and to provide a warning,” he says. “In other words, if this object was bigger and potentially threatening to people on the ground, it would have appeared brighter and projected farther. So this is a really cool demonstration that our current survey systems work really well. Right now, we’re probably averaging about one asteroid per year that gets detected before it hits the atmosphere, and survey systems are getting better and better.”
Not only is Earth developing and improving its early warning systems, but in 2022 NASA’s Dual Asteroid Reorientation Test (DART) spacecraft proved it could potentially save Earth from a catastrophic impact with a larger object. DART struck the 160-meter-wide moonlet Dimorphos, slowing it slightly, demonstrating that in theory such a disaster could be averted. Next month, the European Space Agency will launch the Hera mission to study the consequences of the impact up close and further our understanding of planetary defense.
NGC 261 is located within the Small Magellanic Cloud, one of the Milky Way's closest neighbors.
This Hubble Space Telescope image shows the diffuse nebula NGC 261, about 200,000 light-years from Earth in the constellation Sivir. Image courtesy of NASA/ESA/LC Johnson, Northwestern University/Gladys Kober, NASA and The Catholic University of America.
NGC 261 It is a diffuse nebula located about 200,000 light years away in the constellation Tetranychus.
The object, also known as Brook 42, ESO 29-12, and IRAS 00447-7322, Found It was discovered on September 5, 1826 by Scottish astronomer James Dunlop.
“The ionized gas burning up from within this diffuse region characterizes NGC 261 as an emission nebula,” the Hubble astronomers said.
“The stars are so hot that they irradiate the surrounding hydrogen gas, giving the clouds a pinkish-red glow.”
The Hubble Space Telescope has turned its keen eye to NGC 261 to study how efficiently stars form within molecular clouds, extremely dense regions of gas and dust.
“These clouds are often composed of large amounts of molecular hydrogen and are the cold regions where most stars form,” the researchers explained.
“But molecular hydrogen is poorly radiative, making it difficult to measure this fuel for star formation in stellar nurseries.”
“Because they're difficult to detect, scientists instead track other molecules present within the molecular cloud.”
“The Small Magellanic Cloud contains a gas-rich environment of young stars, as well as traces of carbon monoxide, which correlates with hydrogen and is a chemical often used to confirm the presence of such clouds.”
“The combined powers of the ACS and WFC3 instruments allowed us to probe the star formation properties of the nebula through its carbon monoxide content at visible and near-infrared wavelengths,” the scientists said.
“This work helps us better understand how stars form in our host galaxy and in our Galactic neighbours.”
Looking for a good laugh? Check out the subreddit LinkedIn Lunatics. Trust me, it’s worth a visit.
On this subreddit, you’ll find a Financial Expert advocating for the moderation of porn consumption as a healthy practice to share with friends and community. There are also critics using cultural events like the Olympic Games to teach life lessons and even a Marriage agency mistaking LinkedIn for a dating platform.
The subreddit features stories like a social media company’s creative director who almost missed his flight but learned the valuable lesson of taking risks and a guy who learned important life lessons after a tangerine incident. It’s a mix of humor and bizarre LinkedIn encounters.
All this craziness happened in just one week, making it a rollercoaster of absurdity. Despite the entertainment, the main mission on LinkedIn is to focus on work and professional networking.
LinkedIn is a vital platform for business professionals, especially in B2B sales, like myself. However, it can be overwhelming with the constant stream of “visionary leaders” and “strategic innovators” flooding the feed. It’s a mix of greatness and embarrassment, where professionals love and hate the platform simultaneously.
Many users echo the sentiment that LinkedIn needs a revamp. As a dedicated user, I propose two radical changes:
1. Embrace Reddit Over Facebook
Encourage users to post in LinkedIn groups for longer, more engaging content, similar to Reddit’s format. This shift would enhance the user experience and encourage meaningful discussions.
2. Revise Monetization Strategies
LinkedIn should differentiate between serious members and casual users, potentially by raising fees. Additionally, introducing a nominal fee for every accepted connection request could deter spammy behavior.
Adding a “dislike” button could provide constructive feedback and reduce unwanted solicitations. These changes aim to improve the platform’s quality and user experience.
LinkedIn is at a crossroads, where the balance between professionalism and absurdity is tipping. It’s essential to adapt to evolving user needs to maintain relevance and utility.
Cognitive decline is characterized by a decrease in memory, concentration, and thinking abilities. It is common for individuals to experience increased forgetfulness as they age, such as forgetting names or items they intended to purchase.
However, a more frequent occurrence of these symptoms could indicate cognitive impairment, where cognitive function declines faster than expected due to aging. This can be concerning for both the individual experiencing the symptoms and their loved ones.
Common signs of cognitive impairment include:
Forgetting important dates and events
Losing track of thoughts
Feeling overwhelmed by decision-making and planning
Difficulty navigating familiar places
Becoming impulsive
While cognitive abilities naturally decline with age, the extent and speed of decline vary among individuals and are influenced by genetics and family history. Therefore, two people with similar age-related brain changes may perform differently on cognitive tasks, and individuals with Alzheimer’s disease may exhibit similar cognitive abilities but different brain changes.
What can you do now to prevent cognitive decline?
Building cognitive reserve through experiences like education, occupation, and stimulating activities can help individuals cope with age-related changes. Lifestyle factors like diet, exercise, and social interactions also play a role in cognitive health.
Health conditions like high blood pressure, diabetes, depression, and vascular disease can worsen cognitive decline, but lifestyle changes can help manage or prevent these conditions.
Eat a balanced diet with plenty of leafy greens
Stay active
Limit alcohol consumption
Avoid tobacco products

Making positive changes in one area of your life can have ripple effects on other aspects of health. Unhealthy habits can create a chain reaction of negative health outcomes, while healthy choices can improve overall well-being.
Habits to avoid
A high-fat diet can increase the risk of obesity, diabetes, and cognitive impairment, while smoking can impact lung capacity and cognitive function. By adopting a low-fat diet and avoiding tobacco products, individuals can reduce their risk of cognitive decline.
While we may not be able to prevent cognitive decline entirely, adopting a healthy lifestyle can help build cognitive reserve and potentially slow the decline. Research is ongoing to uncover more about the factors influencing cognitive health.
Aim for an overall healthier lifestyle
In addition to diet and exercise, engaging in social and sexual activities can benefit cognitive health. Social interactions can stimulate the brain and slow cognitive decline, while maintaining romantic and intimate relationships may improve cognitive function.
Stimulating activities like reading, playing games, or learning new skills can also help prevent cognitive decline. Gender differences in cognitive lifestyle choices may influence cognitive outcomes, highlighting the importance of varied activities for cognitive health.
Get a good night’s sleep
Sleep plays a crucial role in cognitive function, with adequate rest linked to better cognitive outcomes. Napping and getting around eight hours of sleep nightly can help reduce the risk of cognitive decline.
Quality sleep is essential for focus, creativity, and decision-making, while sleep deprivation can negatively impact physical and cognitive health. Establishing good sleep habits is key to maintaining cognitive function as we age.
Regular dental checkups can help prevent cognitive decline
Research suggests that gum disease bacteria may be linked to Alzheimer’s and dementia development, emphasizing the importance of oral health for cognitive well-being. By practicing good oral hygiene and seeking regular dental care, individuals can potentially reduce their risk of cognitive decline.
While there is no miracle cure for cognitive decline, taking proactive steps to improve overall health can slow the rate of decline associated with aging. It’s crucial to address any concerns about cognitive function with a healthcare provider to explore potential treatment options.
CoulombFly, a prototype of a small solar-powered drone
Wei Shen, Jingze Peng, and Mingjin Qi
Weighing just 4 grams, the drone is the smallest solar-powered aircraft ever to fly, thanks to special electrostatic motors that generate extremely high voltages and tiny solar panels. Though the hummingbird-sized prototype only lasted an hour, developers say the approach could lead to insect-sized drones that can remain airborne indefinitely.
Small drones are an attractive solution to a variety of problems in communications, espionage and search and rescue, but they suffer from short battery life, while solar-powered drones struggle to generate enough power to be self-sustaining.
When solar-powered drones are made smaller, the solar panels become smaller and the amount of available energy decreases. Minjin Chee Researchers from China's Beihang University say the efficiency of electric motors also declines as more energy is lost as heat.
To avoid this decay cycle, Qi and his colleagues developed a simple circuit that boosts the voltage generated by solar panels to between 6,000 and 9,000 volts. They powered the 10-centimeter rotors using an electrostatic propulsion system, rather than using electromagnetic motors like those used in electric cars, quadcopters, and a variety of robots.
The motor works by alternately attracting and repelling charged parts arranged in a ring, generating torque to spin a single rotor blade like a helicopter. The lightweight parts are made from ultra-thin carbon fiber covered with very delicate aluminum foil. The high voltage requirement is actually an advantage, as the current is reduced, resulting in very little heat loss.
“T“The motor generates very little heat because the operating current is very low for the same power output. The motor's high efficiency and low power consumption allow the vehicle to be powered by very small solar panels,” Qi said. “For the first time, we have successfully flown a micro air vehicle using natural light; previously, this was only achievable with very large ultralight aircraft.”
The machine, which the researchers call the “CoulombFly,” weighs just 4.21 grams and could fly for an hour before it failed. Qi says these weaknesses can be eliminated by design, and future versions could fly essentially indefinitely, using solar panels during the day and powering themselves from radio signals like 4G or Wi-Fi at night.
CoulombFly has a payload capacity of 1.59 grams, allowing it to carry small sensors, computers, and cameras, but with improved designs, the researchers believe this can be increased to 4 grams, and the fixed-wing version could carry up to 30 grams. An even smaller version of CoulombFly, with rotors less than 1 centimeter in diameter, is also in development.
Dead Planets Society is a podcast that explores wild ideas about manipulating the universe and tests them against the laws of physics, from splitting the moon to creating catastrophic events with gravitational waves. Listen on Apple Podcasts, Listen on Spotify or visit our podcast page.
In the early universe, there may have been tiny black holes as massive as mountains but smaller than atoms. If these primordial black holes exist, they could address major cosmological issues and offer endless opportunities for the Society of Dead Planets to explore.
In this episode, hosts Chelsea White and Leah Crane are joined by black hole experts like Alison Kirkpatrick. Researchers at the University of Kansas are investigating the effects of placing a primordial black hole inside different objects, such as the Sun, Earth, or even the human body, yielding surprising results.
A small black hole inside a star or planet would have minimal impact, either passing through or staying near the center depending on the object’s mass. However, a larger black hole the size of Earth but with the radius of a grape could drastically alter the fate of the Sun or consume a planet from within.
Despite the risks, a black hole of this size could potentially manipulate gravity to reshape the universe. For instance, a small black hole near the Moon’s surface could counteract its drift away from Earth.
Kirkpatrick explains that standing a few meters away from a small black hole is relatively safe, but closer proximity would result in gravitational forces tearing apart the nearest parts of the body. Introducing a black hole into the body, even through teleportation, is not advisable.
Kirkpatrick strongly advises against placing a primordial black hole inside the human body due to the immediate havoc it would wreak. The American Medical Association did not provide a response regarding the effects of black holes on humans.
Ocean worlds are planetary bodies with liquid oceans, often beneath an icy shell or within rocky interiors. In our solar system, several moons of Jupiter and Saturn are ocean worlds. Some ocean worlds are thought to have hydrothermal circulation, where water, rocks, and heat combine to pump and expel fluids to the ocean floor. Hydrothermal circulation influences the chemical composition of the water and rocks of ocean worlds and may help life develop deep beneath the icy surface. In a new study, planetary researchers used computer simulations of hydrothermal circulation based on well-understood systems on Earth to measure the effects of low gravity at values appropriate for ocean worlds smaller than our home planet. Simulations of ocean worlds with (lower) gravity result in fluid circulation that is roughly similar to that which occurs above and below the ocean floor on Earth, but with some key differences. Low gravity reduces buoyancy, so fluids do not become lighter as they heat up, which reduces their flow rate. This increases the temperature of the circulating fluids, which could lead to more extensive chemical reactions, possibly including those necessary to support life.

Rock-heat-fluid systems were discovered on the Earth’s ocean floor in the 1970s, where scientists observed releases of fluids carrying heat, particles, and chemicals.
Many of the vents were surrounded by a novel ecosystem, including specialized bacterial mats, red and white tube worms and heat-sensing shrimp.
For the new study, Professor Andrew Fisher from the University of California, Santa Cruz, and his colleagues used a complex computer model based on the hydrothermal cycle that occurs on Earth.
After varying variables such as gravity, heat, rock properties and depth of fluid circulation, the researchers found that hydrothermal vents could persist under a wide range of conditions.
If these flows occurred on an ocean world like Jupiter’s moon Europa, they could increase the chances of life surviving there as well.
“This study suggests that extraterrestrial ocean worlds may have supported low-temperature (but not hot enough for life) hydrothermal systems on timescales similar to those it took for life to become established on Earth,” Prof Fischer said.
The ocean circulation system on which the researchers based their computer model was discovered on the 3.5-million-year-old seafloor of the northwest Pacific Ocean, east of the Juan de Fuca Ridge.
There, cold undersea water flows through an extinct volcano (seamount), travels about 30 miles (48.3 km) underground, and then flows out into the ocean through another seamount.
“As water flows, it picks up heat, it’s warmer than when it entered, and its chemistry changes dramatically,” says Kristin Dickerson, a doctoral student at the University of California, Santa Cruz.
“The flow from seamount to seamount is driven by buoyancy – as water warms it becomes less dense and as it cools it becomes more dense,” Prof Fischer added.
“The difference in density creates a difference in fluid pressure within the rock, and the system is sustained by the flow itself. So as long as there is enough heat supplied and the rock properties allow for sufficient fluid circulation, the system will keep running. We call this a hydrothermal siphon.”
“Hot vent systems are primarily driven by sub-sea volcanism, while the Earth’s ocean floor experiences large amounts of fluid flowing in and out at much cooler conditions, driven primarily by Earth’s background cooling.”
“The flow of water through low-temperature vents is equivalent to all the rivers and streams on Earth in terms of the volume of water released, and accounts for about a quarter of the Earth’s heat loss.”
“About every 500,000 years, the entire volume of ocean water is pumped up and out of the ocean floor.”
Many previous studies of the hydrothermal circulation on Europa and Enceladus have considered hotter fluids.
“Cartoons and other illustrations often depict undersea systems that are similar to Earth’s black smokers, where cooler currents could occur just as much or even more than they do on Earth,” said Dr Donna Blackman from the University of California, Santa Cruz.
The results show that in very low gravity, such as on the ocean floor of Enceladus, the circulation can continue at low to moderate temperatures for millions or billions of years.
This could help explain why small ocean planets can have long-lived fluid circulation systems beneath their seafloors despite limited heating: the inefficiency of heat extraction could extend their lifetimes considerably, potentially for the entire lifetime of the solar system.
Scientists acknowledge that it is uncertain when active hydrothermal systems will be directly observed on the ocean planet’s seafloor.
The distance from Earth and physical characteristics pose significant technical challenges for spacecraft missions.
“It is therefore essential to make the most of the available data, much of which is remotely collected, and to leverage the understanding gained from decades of detailed study of the analog Earth system,” the authors concluded.

Amsterdam’s tiny street gardens provide habitat for insects
Marijke Thyssen/Shutterstock
A study of small urban gardens in the Netherlands found that they can be havens for insects and other wildlife. The two most effective factors were having a lot of plants and a wide variety of plants, whether or not the plants were native.
“Even in a really small garden, just a few plants can make a big difference.” Joe Morpurgo At Leiden University in the Netherlands.
Morpurgo says there have been some studies on biodiversity in larger gardens, but virtually none on smaller ones, so in 2019 his team surveyed 65 urban gardens in Amsterdam and The Hague, all measuring less than 10 square metres.
The researchers measured factors such as the total number of insects, the number of different species, whether the plants were native, and the area covered by the plants. Plant cover was calculated by adding up the area covered by individual specimens, so the garden’s cover can be greater than the area of the land due to plant overlap.
The researchers found that insect abundance and species richness were strongly correlated with plant cover and plant richness, but surprisingly, neither garden size nor native plant cover made any difference.
In theory, native plants should be better: Pollinating insects often adapt to particular flower shapes, and some plant-eating insects will eat specific varieties.
There are several possible explanations for why the proportion of native plants had no effect, Morpurgo said. For example, insects that breed in cities could be omnivorous, or many of them could be invasive species (the study did not categorize insects as native or not).
A study on the large-scale gardens of Wisley, England produces almost the same results“The more plant matter there is, the more invertebrates there are.” Andrew Salisbury These studies were led by staff from the Royal Horticultural Society (RHS).
But one RHS study found that native plants could support slightly higher numbers of plant-eating species, such as caterpillars, Salisbury said.
Morpurgo said he would continue to encourage people to grow native plants, which he said have many more benefits, including cultural value as well as helping insects.
His main advice is to do nothing and just allow plants, even those we might call weeds, to grow and attract wildlife: “If you leave everything alone, nature will come into your garden,” says Morpurgo.
Two teeth from the newly identified ancient ape Buronius manfredschmidi, viewed from multiple angles
Böhme et al., 2024, PLOS ONE, CC-BY 4.0
A small, herbivorous ape may have lived in Western Europe 11.6 million years ago. Smaller and lighter than any great ape known to date, the newly discovered 10-kilogram (22-pound) primate was probably a skilled climber that ate leaves, researchers say. Madeline Boehme At the University of Tübingen, Germany.
“This is a fairly small primate,” she says, “but it's different from all the known fossils and certainly different from all the modern great apes we've known so far.”
About 15 million years ago, during the Miocene, hominoids (great apes) became rare in Africa and more abundant in Europe. Hominoids sometimes shared habitats with other primates, including apes and pliopithecoids, extinct relatives of Old World monkeys, but hominoids do not appear to have coexisted with each other in Europe.
In 2019, Boehme and his colleagues reported the discovery of 37 bones at the Hammerschmiede site in Bavaria that appear to belong to an early, bipedal ape dating back 11.6 million years ago, which they named “hominoid.” Danubius Guggenmosi.
During the excavation, Boehme was surprised to find two small ape-like teeth and a kneecap in the same sedimentary layer. Danubius fossil.
“We kept saying, 'What is this?'” she says of these tiny fossils, “and we concluded that this is clearly something new.”
The fossils are too old for DNA analysis, Boehme said, so the researchers took detailed measurements of the juvenile's 7-millimeter-long molar and 16-millimeter-wide kneecap, as well as a fragment of a premolar that they believe to belong to a young adult. They also calculated the thickness of the enamel and took microscopic CT scans of the teeth.
The gorilla-like thin enamel suggests they probably ate soft foods like leaves, Boehme said, and the shape, thickness and ligament attachment sites of the kneecap are similar to those of arboreal primates, suggesting the apes were good climbers.
Researchers look at new ape Bronius ManfredschmidyThe fossil, named after the medieval name of the nearby Hammerschmiede site, was discovered by dentist Manfred Schmidt, who has been collecting fossils at the site since the 1970s.
Lack of competition for resources Bronius and Danubius Apes can coexist, says Boehme – Danubius They are thought to have eaten tough foods such as nuts and meat, and the team can't rule out the possibility that great apes, which could have been up to three times as heavy, may have preyed on smaller species, she added.
But these three fossils alone may not be enough to reach such a “big” conclusion, the researchers say. Sergio Almesia It is on display at the American Museum of Natural History in New York City. “Small fossil elements may date to infancy. Danubius “The teeth definitely look like baby teeth. [baby teeth]. “
He also thinks the kneecap may represent the same species as the tooth: “It has been suggested that it belongs to a juvenile individual, but its size overlaps with the lower range of adult orangutans.” [which are much larger apes]” says Almesija.
Clement Zanolly A researcher from the University of Bordeaux in France also has doubts: “I'm not sure whether the teeth, especially the molars, belong to a hominoid or to another primate superfamily, a pliopithecoid.”
Boehme and his colleagues say their comparison rules out the possibility that the tooth is a milk tooth or a pliopithecoid tooth.
In any case, the fact that the two primate species shared the same habitat and possibly even interacted with each other is a “fantastic discovery,” Zanolli said, “and it reinforces the idea that Europe at that time was a luxurious and comfortable place for primates to evolve.”
Triangular gold flakes can be manipulated using mysterious quantum forces
George Zograf
A tiny gold device for controlling light is built using strange quantum effects hidden in seemingly empty space.
In 1948, physicist Hendrik Casimir theorized that when objects are brought close together in space, some objects experience a very weak gravitational pull due to imperceptible flickering of quantum fields in the gaps between them. Ta. Researchers then confirmed this Casimir effect in the laboratory. Betul Kyucukoz and his colleagues at Sweden’s Chalmers University of Technology have found a way to make this useful.
They wanted to build a cavity that would trap the light using two pieces of gold placed parallel to each other, so that the light would bounce back and forth between them and would not be able to escape. First, we created the bottom edge of the cavity by transferring triangular gold flakes ranging in size from 4 to 10 microns onto a small piece of glass. The top end of the cavity also contained a triangular gold flake, but instead of holding it in place with an instrument, the researchers attached it to the glass in a salt water solution containing an additional triangular gold flake. The gold flakes were then dipped in and then allowed to develop. Instead, work naturally.
One of those forces was the electrostatic force caused by the charge associated with the dissolved salt. Another is the Casimir effect. Kyuchkoz said he observed the experiment under the microscope many times and could always see the Casimir effect in action. This causes the floating gold flakes to move towards the gold flake where one is imprinted on the glass, and then he moves over the imprinted gold flake until the triangular footprints of the two flakes match. It was rotated.
This completes the assembly of a cavity that can trap light. The researchers were able to significantly control the cavity formation process, Kyucukoz said. For example, by using different concentrations of salt, we can adjust the strength of the electrostatic force so that the distance between the flakes is different for each cavity, creating cavities with slightly different dimensions of 100-200 nanometers. It can trap colored light.
Raul Esquivel Sirbento The professor at the National Autonomous University of Mexico said the idea of self-assembly, likened to throwing a Lego set into a pot and a structure emerges without having to manually press the pieces together, is not new. But he said his team’s experiment was more detailed and controlled than previous attempts to exploit the Casimir effect for similar purposes. But the Casimir effect can be very subtle, so there may be other effects here as well that haven’t been detected yet, Esquivel Servent said.
In the future, Küçüköz and his colleagues hope to use the cavity as part of more complex experiments with light, such as placing objects inside the cavity between two gold flakes.
Astronomers using the NASA/ESA Hubble Space Telescope have captured an excellent image of the spiral galaxy ESO 422-41 in the constellation Columba.
This Hubble image shows ESO 422-41, a spiral galaxy located in the constellation Columba, about 34 million light-years away. Image credit: NASA / ESA / Hubble / C. Kilpatrick.
ESO 422-41 It is located in the constellation Columba, about 34 million light years away.
DDO 230, LEDA 16864, or UGCA 103, the diameter of this spiral galaxy is 30,000 light years.
“The name ESO 422-41 comes from its appearance in the European Southern Observatory (B) Atlas of the Southern Sky,” Hubble astronomers said.
“In the era before automated sky surveys by space observatories such as ESA's Gaia satellite, large-scale photographic surveys discovered many stars, galaxies, and nebulae.”
“Astronomers used the then most advanced large telescopes to create hundreds of photographs covering parts of the sky.”
“They then studied the resulting photographs and attempted to catalog all the new objects revealed.”
“In the 1970s, a new telescope at ESO's La Silla facility in Chile probed the southern sky, which had not yet been explored as deeply as the northern sky,” they added.
“At that time, the primary technology for recording images was glass plates treated with chemicals.”
“The resulting collection of photographic plates became the ESO (B) Atlas of the Southern Sky.”
“Astronomers from ESO and Uppsala, Sweden, worked together to study the plates and recorded hundreds of galaxies (ESO 422-41 is just one of them), star clusters and nebulae. I was a beginner.”
“Since then, astronomical sky surveys have progressed from digital, computer-aided surveys such as the Sloan Digital Sky Survey (SDSS) and Legacy Survey to surveys performed by space telescopes such as Gaia and the Wide-Field Infrared Survey Explorer (WISE). It has transitioned to
“Nonetheless, photographic sky surveys have made significant contributions to astronomical knowledge over the decades, and the glass plate archive serves as an important historical reference for a wide range of skies. .”
“Some of them are still actively used, for example, to study variable stars over time,” the researchers pointed out.
“And the objects revealed by these surveys, including ESO 422-41, can now be studied in detail with telescopes like Hubble.”
The new images of ESO 422-41 consist of observations from Hubble's advanced survey camera (ACS) in the near-infrared and optical portions of the spectrum.
Two filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

Poor and outdated technology is costing the United States enormous amounts of money.according to recent columns The Wall Street Journal said it would cost more than $1.5 trillion to fix, with “cybersecurity and operational failures, failed development projects, and maintenance of outdated systems costing $2.41 trillion annually.” There is.
According to the magazine, this “technical debt” lurks beneath the shiny newness of “an accumulation of band-aids and outdated systems not intended for today's use,” all of which need updating. It is said to be extremely sensitive.
And I don't know that.
I've been dealing with this problem every day for the past 20 years. My life revolves around outdated systems, outdated software, and patched databases. My company sells customer relationship management (CRM) software primarily to small and medium-sized businesses. And look at the old technology they still have.
It's not uncommon to come across older versions of Microsoft Office. One of his companies I know is still running Office 97. I see companies using QuickBooks on desktop computers. Remember ACT and GoldMine for contact managers? Yes, they're still there. Great Plains? MAS90? Yes, there are still remnants of these ancient accounting systems in today's products manufactured by Microsoft and Sage.
It's not uncommon to encounter companies with internal networks running legacy client/server applications on Windows machines.Approximately 81% of companies still writing paper checks to suppliers. My company's biggest competitor is not any other CRM software. Someone is walking away from a prehistoric, proprietary system built on top of his FileMaker Pro, which hasn't been updated since the system's creator passed away ten years ago.
Over the years, I have never faulted small business owners for not upgrading.
These people spent a lot of money implementing software systems back in the day. They'd have to come up with a pretty good reason to scrap it all and start fresh. Cloud? Better security? More integration? Maybe. But then again, wouldn't that money be better spent buying new equipment, repairing the warehouse roof, or medical care? And don't we hear about the mistakes made by ~? ? microsoft and Google And A.I. “hallucination” And that data breach Are the world's smartest people at the biggest technology companies that are supposed to work for them? Can we trust these companies and their shiny new applications? Why invite trouble?
Replacing or upgrading technology is one of the many decisions businesspeople have to make every year. They know the chaos it causes. And many of my clients shrug their shoulders and say it's not broken so why fix it?
Understood. But now my feelings are starting to change. No, I'm not siding with big tech companies. It's about inheritance.
More than half of small business owners in this country are over 50 years old, and the baby boomers currently running companies will likely aim to take the next step in the not-too-distant future. They expect to make the most money from the business they have built over the past few decades. But the same people who saved money on technology upgrades to invest elsewhere will be shocked. why?
Because this is a world of big data and unless the technology is up to date, the price of your business will be greatly affected. This is not a technical issue. It's a matter of evaluation. Buyers will quickly discount the purchase price to cover the cost of having to upgrade or replace these older systems.
My advice to business owners looking to leave their companies within the next 10 years is that it's time to upgrade. Otherwise, “technical debt” will cost you dearly.
Cognitive decline is characterized by a decline or slowing of memory, concentration, and thinking abilities. It’s common for individuals to experience increased forgetfulness as they age, such as forgetting names or shopping lists.
If the frequency of forgetful episodes is escalating and the decline is faster than expected for normal aging, it could indicate cognitive impairment. This can be concerning for the individual experiencing symptoms as well as their family and friends.
Common signs of cognitive impairment include forgetting important dates, losing track of thoughts, feeling overwhelmed with decisions, getting lost in familiar places, and becoming more impulsive.
Cognitive decline varies among individuals and is influenced by genetics and family history. Building cognitive reserve through a lifetime of experiences, including education, career, and engaging activities, can help mitigate the effects of aging on cognitive function.
What can you do now to prevent cognitive decline?
Developing a “cognitive reserve” through education, occupation, and engaging activities can help bolster cognitive function. Lifestyle factors like diet, exercise, and avoiding tobacco and alcohol can also impact cognitive health.

Positive lifestyle changes in areas like diet and exercise can have cascading health benefits. Conversely, unhealthy habits can lead to adverse health effects.
Habits to avoid
Studies show that high-fat diets and smoking can contribute to obesity, diabetes, and cognitive decline. Maintaining a balanced lifestyle with good nutrition, physical activity, and healthy habits can help prevent cognitive decline.
Cognitive decline is a natural part of aging, but taking steps to build cognitive reserve and adopt a healthy lifestyle can help slow its progression.
Aim for an overall healthy lifestyle
Incorporating social activities, hobbies, and maintaining intimate relationships can also play a role in preventing cognitive decline. Engaging in challenging activities and stimulating the brain through hobbies can help preserve cognitive function.
Sex on the brain
Maintaining romantic and intimate relationships can have a positive impact on cognitive health. Research suggests a link between sexual activity and cognitive function, possibly due to social connections and hormonal influences.
Indulging in hobbies and activities, getting quality sleep, and regular dental checkups can also contribute to maintaining cognitive function as we age. It’s important to address any concerns about cognitive abilities with a healthcare professional for proper evaluation and guidance.
NASA has released a beautiful photo of spiral galaxy NGC 4423 taken by the Hubble Space Telescope.
This Hubble image shows spiral galaxy NGC 4423 about 55 million light-years away in the constellation Virgo. Image credit: NASA / ESA / Hubble / M. Sun.
NGC4423 It is located in the constellation Virgo, about 55 million light years away.
Also known as IRAS 12246+0609, LEDA 40801, or VCC 971, this spiral galaxy is approximately 35,000 light-years in diameter.
beginning spotted Discovered on April 13, 1784 by German-born British astronomer William Herschel, NGC 4423 is a member of the Virgo cluster.
“In the new image, NGC 4423 appears to have a highly irregular, tubular shape, so it may be surprising to learn that it is actually a spiral galaxy,” Hubble astronomers said in a statement.
“Knowing this, we can distinguish between the galaxy's denser central bulge and the less dense surrounding disk, which makes up the spiral arms.”
“If you looked at NGC 4423 head-on, it would resemble the shape we most associate with spiral galaxies: a spectacular curve spreading out from a bright center and interspersed with darker, dimmer, less populated regions. This is the arm you are drawing.”
“However, when observing the sky, we are constrained by the relative position of the earth and the object we are observing. We cannot simply change the position of the earth to get a better view of NGC 4423 head-on. .”
“Of course, celestial bodies are not stationary in space; they often move at very high speeds relative to each other.”
“This may suggest that even if the galaxy is moving in a coincidental direction relative to Earth, if you travel far enough you may be able to see it from a substantially different perspective. I don’t know.”
“While this is theoretically possible, in reality the distances in the universe are too long and human lifespans are too short for significant differences in relative alignment to occur.”
“In other words, this is more or less the view of NGC 4423 that we will always have.”
New images of NGC 4423 consist of observations from. Hubble's advanced survey camera (ACS) in the near-infrared and optical portions of the spectrum.
This is based on data obtained through two filters. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.
Danionella cerebrumThis translucent fish species, only 12 mm long, produces high-amplitude sounds exceeding 140 dB (1 µPa relative at a distance of 1 body length). This is comparable to a jet engine taking off at a distance of 100 meters.
Danionella cerebrum It has a pair of extrinsic indirect muscles that house the drumming cartilage. When the sonic muscles contract, they pull the fifth rib forward, pulling on the cartilage and increasing tension. When the cartilage is suddenly released, it rapidly impinges on the swim bladder, producing a short, loud pulse. Bursts of pulses are produced by bilateral alternating or unilateral muscle contractions. In summary, this mechanism allows for loud, stereotypical sounds elicited in structured sequences, making it unique for vertebrate acoustic communication and ultrafast skeletal locomotion that exceeds the limitations of muscle contraction velocity. It will be a solution. Image credit: Ralf Britz, Senckenberg Natural History Collections.
“Oyster oyster shrimp can make crackling noises of up to 250 dB with their claws,” he said. Dr. Ralph Blitzichthyologist at the Senckenberg Natural History Collection.
“The flightless kakapo’s mating call can reach 130 dB, and elephants can make up to 125 dB of noise with their trunks.
“Fish, on the other hand, are generally considered to be fairly quiet members of the animal kingdom.”
“But certain fish species can be surprisingly noisy. For example, male redfin midshipmanfish attract females with an audible vibrato of about 100 Hz and 130 dB.”
In a new study, Dr. Blitz and his colleagues looked into Danionella cerebruma small teleost fish with the smallest brain of any known vertebrate.
“This small fish can emit over 140dB of sound at a distance of 10-12mm, which is comparable to the noise of a plane taking off at a distance of 100m, which is highly unusual for such a fish. 'It's a small size,' Dr. Blitz said.
“We sought to understand how the fish manage this and what mechanisms are involved in this outcome.”
Using a combination of high-speed video, microcomputed tomography, gene expression analysis, and differential methods, the researchers discovered that: Danionella cerebrum Males have unique sound-producing equipment, including drumming cartilage, specialized ribs, and fatigue-resistant muscles.
“This device accelerates the drumming cartilage with a force of more than 2,000g and slams it against the swim bladder, producing rapid and loud pulses,” Dr. Blitz said.
“These pulses chain together to produce calls for bilateral alternating or unilateral muscle contractions.”
Due to its small size and lifelong light transmission, Danionella cerebrum It is a new model organism for biomedical research.
This species lives in the shallow, murky waters of Myanmar.
“It is likely that competition between males in this visually restricted environment contributed to the development of specialized mechanisms for acoustic communication,” Dr Blitz said.
The results of this study cast doubt on the conventional concept that the speed of skeletal movement in vertebrates is limited by muscle movement.
“Understanding unusual adaptations Danionella cerebrum “This extends our knowledge of animal locomotion and highlights the remarkable diversity of propulsion mechanisms in different species,” the authors said.
“This contributes to a broader understanding of evolutionary biology and biomechanics.”
“Sounds made by others are Danionella The species has not yet been studied in detail. It would be interesting to know how their sound production mechanisms differ and how those differences relate to evolutionary adaptations. ”
“Combined with its lifelong transparency, this genus Danionella This provides a unique opportunity to compare the neural mechanisms underlying sound production between different species. ”

A device that can measure the force of gravity on particles lighter than a single grain of pollen could help us understand how gravity works in the quantum world.
Despite being stuck to the ground, gravity is the weakest force known to us. Only very large objects, such as planets and stars, generate enough gravity to be easily measured. Doing the same for a very small object at a fraction of the distance and mass in the quantum realm is also possible because the size of the force is so small, but a nearby larger object could overwhelm the signal. It is very difficult because there is
now hendrik ulbricht and colleagues at the University of Southampton in the UK have developed a new way to measure gravity on a small scale, using tiny neodymium magnets weighing about 0.5 milligrams that are suspended in a magnetic field that opposes Earth's gravity.
Small changes in the magnetic field of a magnet caused by the gravitational influence of nearby objects can be converted into a measure of gravity. The whole thing is cooled to near absolute zero and suspended on a spring system to minimize external forces.
This probe can measure the gravitational pull of objects weighing just a few micrograms. “We can increase the sensitivity and push the study of gravity into a new regime,” Ulbricht says.
He and his team found that a 1-kilogram test mass rotating nearby could measure a force of 30 atton-Newtons on a particle. An atnewton is one billionth of a newton. One limitation is that the test mass must be moving at a suitable velocity to cause gravitational resonance with the magnet. Otherwise, it will not be strong enough to pick up the force.
The next stage of the experiment will reduce the test mass to the same size as the magnetic particles so that gravity can be tested while the particles exhibit quantum effects such as entanglement and superposition. Ulbricht said this would be difficult because with such a small mass, all other parts of the experiment would need to be incredibly precise, such as the exact distance between the two particles. Masu. It may take at least 10 years to reach this stage.
“The fact that they even attempted this measurement is appalling to me,” he says. julian starlingis a UK-based engineer, as it is difficult to separate other gravitational effects from the exploration mass. Professor Starling said that in this experiment, the anti-vibration system appeared to have had a small but significant effect on airborne particles, so researchers need to find ways to minimize the gravitational effects of the anti-vibration system. It states that there is.
A new genus and species of dwarf lambeosaurid hadrosauridae have been discovered in Moroccan rocks dating back to the late Cretaceous period, approximately 68 million years ago.

“Dalatypus dinosaurs, or hadrosaurs, were highly successful herbivores that caused large-scale radioactivity in the Late Cretaceous,” said paleontologists from the University of Bath. Nicholas Longrich and his colleagues.
“Hadrosaurids evolved in North America during the Turonian period (94 to 90 million years ago) and then dispersed to Asia and Europe.”
“The presence of hadrosaurids in Africa is puzzling because Africa had been isolated from Laurasia by the deep ocean since the Middle Jurassic, whereas hadrosaurids evolved in the Late Cretaceous.”
“The solution to this contradiction seems to be that the platypus either swam to Africa or crossed there on a raft.”
The newly described hadrosaurid species lived in Africa during the late Maastrichtian period of the Late Cretaceous period, about 68 million years ago.
named Mincaria Batathis dinosaur was relatively small, measuring about 3.5 meters (11.5 ft) in length.
This species comes from the phosphate mines of Sidi Chennan, Morocco, the same locality where the hadrosaur family Lambeosaurus was produced. Ajnavia Odysseusand based on a partial skull.
belongs to Areni Saulinia clade of lambeosaurid hadrosaurids endemic to Europe and North Africa.
“Mincaria Bata is distinguished from Ajnavia Odysseus “This is due to the shape of the maxilla, which has a more ventrally located zygomatic surface, a curved external ridge, a more sinusoidal tooth row, and an array of neurovascular foramina,” the paleontologists said.
“But the new species is very similar. Ajnavia Odysseus Other arenisaurines also have their small size and many anatomical features. ”

Researchers also unearthed the fossilized remains of two other hadrosaurids at the Sidi Daoui and Mura Larak sites.
“The humerus and femur belong to a larger hadrosaurid, measuring 6 meters (20 feet) long, suggesting that at least three species coexisted,” the researchers said.
Research team's analysis suggests a group of hadrosaurs lambeosauridae It first diversified in Asia and later dispersed to North America.
Dispersal from Asia to Europe was followed by dispersal to North Africa. Multiple dispersals from Europe to Africa appear to be more parsimonious than a single dispersal, but are not impossible, especially considering its unique morphology. Ajnavia Odysseus and Mincaria Bata.
“Hadrosaurid diversity in Europe and Africa suggests a dispersal radiation, with lambeosaurs taking advantage of low ornithischian diversity to diversify,” the scientists said. Stated.
“However, African lambeosaurs are smaller than their North American and Asian counterparts, probably due to competition with titanosaurs.”
“The lack of known hadrosaurids from eastern Africa suggests that Moroccan hadrosaurids are part of a distinct island fauna and may represent an island radiation.”
of findings appear in the diary scientific report.
