We May Never Know the Universal Wave Function

From the perspective of quantum physics, the universe may be fundamentally agnostic in some respects.

In quantum physics, every object, such as an electron, corresponds to a mathematical entity known as a wave function. This wave function encodes all details regarding an object’s quantum state. By combining the wave function with other equations, physicists can effectively predict the behavior of objects in experiments.

If we accept that the entire universe operates on quantum principles, then even larger entities, including the cosmos itself, must possess a wave function. This perspective has been supported by iconic physicists like Stephen Hawking.

However, researchers like Eddie Kemin Chen from the University of California, San Diego and Roderich Tumulka from the University of Tübingen in Germany, have demonstrated that complete knowledge of the universal wave function may be fundamentally unattainable.

“The cosmic wave function is like a cosmic secret that physics itself conspires to protect. We can predict a lot about how the universe behaves, yet we remain fundamentally unsure of its precise quantum state,” states Chen.

Previous studies assumed specific forms for the universal wave function based on theoretical models of the universe, overlooking the implications of experimental observations. Chen and Tumulka began with a more practical inquiry: Can observations help in identifying the correct wave function among those that reasonably describe our universe?

The researchers utilized mathematical outcomes from quantum statistical mechanics, which examines the properties of collections of quantum states. A significant factor in their calculations was the realization that the universal wave function depends on numerous parameters and exists in a high-dimensional abstract state.

Remarkably, upon completing their calculations, they found that universal quantum states are essentially agnostic.

“The measurements permissible by the rules of quantum mechanics provide very limited insight into the universe’s wave function. Determining the wave function of the universe with significant precision is impossible,” explains Tumulka.

Professor JB Manchak from the University of California, Irvine states that this research enhances our understanding of the limits of our best empirical methods, noting that we essentially have an equivalent to general relativity within the framework of quantum physics. He adds that this should not come as a surprise since quantum theory was not originally designed as a comprehensive theory of the universe.

“The wave function of a small system or the entire universe is a highly theoretical construct. Wave functions are meaningful not because they are observable, but because we employ them,” remarks Sheldon Goldstein from Rutgers University. He further explains that the inability to pinpoint a unique, accurate universal wave function from a limited range of candidates may not be problematic, as any of these functions could yield similar effects in future calculations.

Chen expresses hope to connect his and Tumulka’s research with the exploration of large-scale systems smaller than the universe itself, especially through techniques like shadow tomography, which aim to determine the quantum state of such systems. However, the philosophical consequences of their work are equally crucial. Tumulka emphasizes the need for caution against over-relying on positivist views that deem non-experimental statements as meaningless or unscientific. “Some truths are real, but cannot be measured,” he asserts.

This rationale might influence ongoing debates regarding the interpretation of quantum mechanics. According to Emily Adlam from Chapman University in California, the new findings advocate for incorporating more components into the interpretation of quantum equations, such as wave functions, emphasizing the relationship between quantum objects and individual observer perspectives, moving away from the assumption of a singular objective reality dictated by a single mathematical construct.

Unlocking the Secrets of Jupiter and Saturn: How Polar Cyclones Expose Hidden Interiors

A groundbreaking study by planetary scientists at the Massachusetts Institute of Technology (MIT) reveals how the significant differences in polar vortex patterns between Jupiter and Saturn are influenced by the unique properties of their deep interiors. These findings offer valuable insights into the structure of these gas giants.

The colors in this image represent radiant heat, revealing temperature variations in their cloud layers. Image credit: NASA / JPL-Caltech / SwRI / ASI / INAF / JIRAM.

“Our study shows that the internal properties, including the softness of the vortex base, influence the fluid patterns observed at the surface,” explained Dr. Wang-Ying Kang from MIT.

The research was inspired by stunning images of Jupiter and Saturn obtained from NASA’s Juno and Cassini missions.

Since 2016, Juno has been orbiting Jupiter and revealing astonishing details about its north pole and intricate spiral formations.

The data suggest that each vortex on Jupiter is immense, measuring around 5,000 km (3,000 miles) in diameter.

Meanwhile, Cassini documented Saturn’s iconic polar vortex, which spans a singular hexagonal shape approximately 29,000 km (18,000 miles) wide, before its controlled descent into Saturn’s atmosphere in 2017.

“Despite their similarities in size and primary composition of hydrogen and helium, deciphering the differences in polar vortices between Jupiter and Saturn has been challenging,” noted MIT graduate student Jial Shi.

Researchers aimed to uncover the physical mechanisms behind the formation of either a single vortex or multiple vortices on these distant planets.

To achieve this, they employed a two-dimensional model of surface fluid dynamics.

While polar vortices are inherently three-dimensional, the fast rotation of Jupiter and Saturn leads to uniform motion along their rotational axes, allowing the team to effectively analyze vortex evolution in two dimensions.

“In rapidly rotating systems, fluid motion tends to be uniform along the axis,” Dr. Kang added. “This insight allowed us to convert a 3D challenge into a 2D problem, significantly speeding up simulations and reducing costs.”

With this in mind, researchers created a two-dimensional model of vortex behavior in gas giants, adapting equations that describe the evolution of swirling fluids over time.

“This equation is commonly used in various situations, including modeling cyclones on Earth,” Dr. Kang stated. “We tailored it for the polar regions of Jupiter and Saturn.”

Scientists applied the two-dimensional model to simulate fluid dynamics on gas giants in various scenarios, adjusting parameters such as planetary size, rotational speed, internal heating, and the characteristics of the fluid.

They introduced random “noise” to simulate initial chaotic fluid flow on the planets’ surfaces.

By analyzing how this fluid evolved over time across different scenarios, the researchers found that some conditions led to the formation of a single large polar vortex, akin to Saturn’s structure, while others resulted in multiple smaller vortices, similar to those on Jupiter.

Through careful examination of the parameters affecting each scenario, the study identified a unifying mechanism: the softness of the vortex base constrains the size that vortices can attain.

The softer and lighter the gas at the bottom of the vortex, the smaller the resulting vortex, enabling multiple smaller vortices to exist at Jupiter’s poles. Conversely, a denser and harder base permits the growth of sizable vortices, manifesting as a singular entity like Saturn.

If this mechanism holds for both gas giants, it could suggest that Jupiter has a softer internal composition, while Saturn may contain denser materials.

“The fluid patterns we observe on the surface of Jupiter and Saturn may provide insights into their interior compositions,” Shi remarked.

“This is crucial because Saturn’s interior likely harbors richer metals and more condensable materials, leading to stronger stratification than that found in Jupiter,” Shi added. “This will enhance our understanding of gas giant planets.”

The team’s findings will be published in the Proceedings of the National Academy of Sciences.

Fossils Unravel the Dietary Secrets of One of History’s Strangest Animals

Hallucigenia: One of the Strangest Animals of All Time

Hallucigenia: One of the Strangest Animals of All Time

Among the most peculiar creatures ever to roam the Earth is Hallucigenia, a scavenger that thrived on the carcasses of Kushi jelly. Recent studies have reinvigorated our understanding of this enigmatic organism first discovered in the 1970s.

Hallucigenia measured approximately 5 cm in length and boasted an insect-like body with multiple legs and lengthy, sharp spines along its back. Its unusual morphology led paleontologists to initially reconstruct it upside down, mistaking its vertebrae for legs.

This unique creature inhabited the deep sea during the Cambrian period, roughly 539 to 487 million years ago, when various major animal groups emerged. Hallucigenia was first identified in the Burgess Shale formation in British Columbia, Canada. It shares evolutionary ties with velvet worms, tardigrades, and arthropods, a group that includes insects and spiders.

Despite the wealth of fossils, much about the lifestyle of ancient creatures such as Hallucigenia remains a mystery. For instance, researchers have yet to determine what they fed on, as existing fossils have not preserved intestinal contents.

Harvard University’s Javier Ortega Hernandez has conducted a thorough investigation of the Burgess Shale fossils. He revisited the original description of Hallucigenia in 1977, which had not been revisited until now.

Among the findings was a fragment of a severely damaged, soft-bodied gelatinous organism measuring 3.5 cm by 1.9 cm, which Ortega Hernández identified as a comb jelly (ctenophore).

He proposed that the spines attributed to Hallucigenia represent a group of seven individuals that voraciously fed on a dead Kushi jelly, which had drifted to the ocean floor. This event likely involved suction feeding, as they were all eventually enveloped in sediment and transformed into fossils.

Ortega Hernández opted against interviews for New Scientist since this research is currently pending peer review.

“This represents a fascinating ecological interaction,” remarks paleontologist Alison Daly from the University of Lausanne, Switzerland, referring to these findings as “snapshots” that capture fleeting moments in the fossil record, lasting perhaps only a few minutes or hours.

As noted by Daly, Hallucigenia thrived in the nutrient-poor depths of the ocean, so it’s plausible that these creatures survived by rapidly locating and consuming abundant food sources like deceased Kushi jelly. “Suction feeding is highly effective for soft-bodied organisms,” she comments.

However, Jean-Bernard Caron of the Royal Ontario Museum in Toronto expresses some skepticism. The fact that fossils of ctenophores were found in proximity to Hallucigenia does not definitively indicate interaction, he suggests, as an underwater landslide could have transported them to the same resting place.

Furthermore, Caron proposes an alternative interpretation: the discovered fossils may simply be detached spines, indicating that these creatures may have shed their skin as they grew.

Discovering a Barred Spiral Galaxy: Unveiling Cosmic Secrets Just 2 Billion Years Post-Big Bang

Using high-resolution images, NIRCam, a near-infrared camera aboard the NASA/ESA/CSA James Webb Space Telescope, has led astronomers to discover COSMOS-74706, one of the earliest known barred spiral galaxies. This discovery is pivotal in shaping our understanding of cosmic evolution.

The barred spiral galaxy COSMOS-74706 existed approximately 11.5 billion years ago.

“This galaxy developed its bar just two billion years after the universe’s inception,” stated Daniel Ivanov, a graduate student at the University of Pittsburgh.

“Stellar bars are linear features found at the centers of galaxies, confirming their namesakes.”

COSMOS-74706’s bar comprises a dense collection of stars and gas, appearing as a bright line bisecting the galaxy when viewed perpendicularly to its plane.

Stellar bars significantly influence a galaxy’s evolution, funneling gas from the outskirts into the center, which feeds the supermassive black hole and can inhibit star formation within the galactic disk.

While previous reports identified barred spiral galaxies, their analyses were inconclusive due to the less reliable optical redshift methods compared to the spectroscopy used for COSMOS-74706 verification.

In some instances, a galaxy’s light was distorted by a massive object, leading to a phenomenon known as gravitational lensing.

“Essentially, COSMOS-74706 is the most redshifted spectroscopically confirmed lensless barred spiral galaxy,” Ivanov noted.

“We were not surprised to find barred spiral galaxies so early in the universe’s timeline.”

“In fact, some simulations suggest the bar formed at redshift 5, or roughly 12.5 billion years ago.”

“However, I believe we shouldn’t expect to find many of these galaxies just yet.”

This discovery helps refine the timeline for bar formation, making it a significant finding.

Ivanov and colleagues presented their discoveries on January 8th during the 247th Annual Meeting of the American Astronomical Society.

Centuries-Old Greenland Sharks Thrive Despite Heart Disease: Secrets to Their Longevity Revealed

Greenland shark

Greenland Sharks’ Longevity: A Closer Look at Their Heart Health

Credit: Doug Perrine/naturepl.com

Greenland sharks are believed to live between 250 to 500 years. Remarkably, even at 150 years old, they show signs of severe age-related heart disease.

Interestingly, some body parts like their eyes seem resilient to aging and cancer, suggesting that not all organs in this ocean predator are equally affected by age. Despite this resilience, research has shown that Greenland sharks (Somniosus microcephalus) do have significant heart health issues, yet they show no obvious functional decline or reduced lifespan.

Alessandro Cellerino and his team at the École Normale Supérieure in Pisa, Italy, conducted a study on six Greenland sharks (four females and two males), each exceeding 3 meters in length, and found their results to be “truly surprising.”

The researchers estimate that all six specimens were between 100 and 150 years old. They employed various advanced microscopic techniques, including high-resolution fluorescence and electron microscopy, to investigate the animals’ heart tissues.

“The hearts of Greenland sharks exhibited significant fibrotic changes and an abundance of aging markers such as lipofuscin and nitrotyrosine,” stated Cellerino.

In humans, elevated fibrosis levels in heart tissues typically signal age-related heart problems and potential heart failure.

Nevertheless, Cellerino noted that the substantial accumulation of lipofuscin, associated with mitochondrial impairment, does not appear detrimental and “does not adversely affect the lifespan of Greenland sharks.”

The high levels of nitrotyrosine, another marker associated with heart inflammation and oxidative stress, suggest that Greenland sharks may have developed a unique evolutionary strategy for enduring chronic oxidative damage, as opposed to merely attempting to avoid it.

“Initially, I thought what I observed under the microscope was a technical artifact or an error in the experiment,” he remarked.

To compare, the researchers also examined another deep-sea fish, the velvet-bellied lantern shark (Etmopterus spinax), along with the turquoise killifish (Nosobranchius furzeri), a species noted for its fleeting lifespan of mere months, residing in seasonal pools across the African savannah.

Elena Chiavatti mentioned that while the Greenland shark’s heart is highly fibrotic, the other species showed no signs of such conditions, as indicated in the Scuola Normale Superiore paper.

“The accumulation of nitrotyrosine is significant in Greenland sharks, whereas lantern sharks show no accumulation,” Chiavatti commented.

Despite their brief lifespans, killifish share similar nitrotyrosine aging markers with Greenland sharks, she added.

Cellerino emphasized that Greenland sharks exhibit extraordinary resilience to aging, particularly in their hearts. “The existence of organisms like Greenland sharks that endure aging without any noticeable heart decline is remarkable,” he noted. “These findings underscore the exceptional heart resilience of Greenland sharks and suggest potential insights into healthy aging.”

João Pedro Magalhães from the University of Birmingham highlighted that the study underscores our limited understanding of the molecular and cellular aging mechanisms, including which changes are detrimental and which are advantageous.

Furthermore, Magalhães urged for a broader variety of animals in aging and lifespan research. “Most scientists, including myself, primarily use short-lived species like earthworms, mice, and rats, but remarkable long-lived species such as Greenland sharks and bowhead whales could hold the keys to longevity,” he urged.

BepiColombo Mission Launches in 2026: Unveiling the Secrets of Mercury

Artist’s Impression of BepiColombo Spacecraft Near Mercury

In 2026, the highly anticipated BepiColombo spacecraft is set to orbit Mercury, promising to unlock the planet’s long-standing mysteries.

BepiColombo is a collaborative mission involving the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA). This intricate mission includes the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (Mio), tethered to the Mercury Transport Module (MTM).

Since its launch in 2018, the MTM has made six flybys of Mercury, skillfully utilizing the planet’s gravity to facilitate its descent into orbit, a method pioneered by Giuseppe “Bepi” Colombo.

This mission has already gathered crucial scientific insights, including data about the solar wind and high-resolution imagery of Mercury’s surface. However, the MPO’s advanced instruments, including X-ray spectrometers, remain inactive due to obstructions by the MTM.

In September 2026, the MPO and Mio will detach from the MTM, embarking on their final descent into orbit, completing this phase by November when their focus will shift to detailed studies of Mercury.

According to Charlie Feldman, a researcher at the University of Leicester who contributed to the MPO’s instruments, “We’re hopeful that our equipment will function as intended. With the extensive time invested in building it, the excitement comes with a degree of anxiety.”

Alongside capturing intricate details of Mercury’s magnetosphere, the MPO will extensively map and analyze the planet’s surface using its spectrometer and other tools. “This represents the first X-ray imagery of an extraterrestrial surface,” Feldman noted.

Such observations may unravel enigmas surrounding the significant X-ray emissions detected from Mercury’s night side in prior missions. Additionally, the spacecraft will assess X-rays emitted from the sun-facing side, unearthing new insights into Mercury’s geological composition and evolution. “Deciphering how planets formed gives us a broader understanding of solar system dynamics,” Feldman stated.

MMX spacecraft visiting Mars moon

MMX Spacecraft to Explore Mars Moons

The mystery surrounding the origins of Mars’s moons, Phobos and Deimos, may soon be unraveled with the launch of the MMX spacecraft, set to return samples from Phobos to Earth in 2026.

“While we understand the origin of Earth’s moon, the origins of Phobos and Deimos remain unclear,” says Emelia Brannagan-Harris from the Natural History Museum in London. “By exploring the origins of these moons, we aim to gain insights into Mars’s evolutionary history.”

There are two leading theories regarding how these moons came to orbit Mars. The first theory suggests that they are remnants of asteroids that either merged and then separated or closely orbit each other. The second theory posits that they may have formed from an asteroid impact on Mars, similar to the formation of Earth’s moon.

Currently, evidence supports neither scenario definitively. However, the Japan Aerospace Exploration Agency’s Mars Moon Explorer (MMX), scheduled for launch in 2026, is equipped to clarify which theory holds true. This spacecraft will observe both moons and send a rover to gather samples from Phobos’s surface and subsurface.

If the observations reveal a prevalence of carbon-rich materials and water, it could support the theory of asteroid capture. Conversely, if such materials are absent, we may need to await the analysis of the collected samples, expected to return to Earth by 2031.

The Phobos samples will include both surface material and samples from beneath the surface. Testing this material will allow scientists to investigate signs of past dissolution, potentially indicating interactions with Mars’s atmosphere or surface.

Regardless of the origins of Phobos, its close orbit around Mars suggests it may hold well-preserved samples from early Mars. “Phobos might also contain ancient debris from Mars’s period of liquid water, offering significant insights into the planet’s history,” Brannagan-Harris emphasizes.

Unlocking Secrets of Dark DNA: Insights from Human-Plant Hybrid Cells

Groundbreaking Discovery: Plant and Human DNA Interaction

Image Credit: S Saraus/Shutterstock

How crucial is our genome? While some researchers argue that most of our DNA is active and thus essential, others suggest that even random DNA could show high activity levels. Current studies focus on human cells that incorporate substantial segments of plant DNA, shedding light on this topic. According to New Scientist, the largely random plant DNA exhibits nearly equal activity to human DNA.

This research indicates that much genomic activity may lack purpose, further supporting the theory that a significant portion of the human genome is ‘junk DNA.’

“Most activity can be attributed to background noise,” says Brett Aidy, a researcher at the University of Auckland, New Zealand. “This aligns with the concept of junk DNA.”

The primary role of DNA is to encode instructions for protein synthesis, which are essential molecular machines responsible for cellular functions. This genetic blueprint is transcribed into messenger RNA, which transports the instructions to ribosomes, the cellular machinery for protein production.

Previously, it was assumed that nearly all DNA was involved in coding proteins, but now we understand that just 1.2% of the human genome directly encodes proteins. What, then, is the destiny of the remaining DNA?

Since the 1960s, biologists have claimed that much of it is unproductive. While it’s true that some non-coding DNA plays vital roles, ongoing discoveries of functional elements won’t redefine the overarching notion that non-coding DNA is largely inert.

For instance, a 2011 study revealed that: only about 5% of the genome is evolutionarily conserved. Evolution appears indifferent to the rest. Proponents of the junk DNA theory highlight the variability in genome sizes among species. Why, for example, does an onion require five times more DNA than a human? Additionally, why do lungfish possess genomes that are thirty times larger?

In contrast, other scientists explore whether human DNA has functional roles, even if converted RNA lacks known applications. The ENCODE project’s 2012 findings suggest that over 80% of the human genome is active in some form. This raised questions about its classification as junk DNA. Some researchers have coined the term “dark DNA” for non-coding regions whose purpose remains unclear.

In reaction to ENCODE’s claims, in 2013, Sean Eddy from Harvard University proposed a controversial random genome project, hypothesizing that injecting synthetic random DNA into human cells would yield similar activity as noted in ENCODE’s findings.

“If this holds true, the results will call into question the interpretation of activity as indicative of functionality,” he posits. Austin Ganley, also from Auckland University, echoes this sentiment, emphasizing the need for baseline comparisons in the research of functional versus non-functional DNA.

However, synthesizing DNA is resource-intensive. So far, only limited attempts at random genome projects have focused on small DNA segments.

Yet, when Adey and Ganley discovered that Japanese researchers had successfully created human-plant hybrid cells with DNA segments from Thale cress (Arabidopsis), they recognized it as potentially the most extensive random genome experiment to date.

Eddy, though not directly involved, acknowledges the significance. Plants and animals diverged from a common ancestor over 1.6 billion years ago, allowing time for random mutations to accumulate within non-coding DNA segments of Arabidopsis.

Following initial validations that plant DNA behaves as random DNA in human cells, Adey and Ganley assessed DNA-to-RNA conversion rates per 1000 base pairs of non-coding DNA. If DNA to RNA conversion implies functionality, plant DNA should minimal undergo this transformation. Surprisingly, they observed slightly less activity—about 80% of the starting sites per kilobase when compared to human non-coding DNA from Arabidopsis.

This strongly indicates that the genomic activity detected by ENCODE is merely background noise.

“This illustrates the inherent noise in biological systems,” comments Chris Ponting from the University of Edinburgh, UK. “This sequence’s biochemical activity holds no function within human cells.”

“Sophisticated investigations like this were essential,” asserts Dan Graul from the University of Houston, Texas. “This adds experimental evidence confirming the long-held belief that a majority of the human genome is unnecessary. The term ‘dark DNA’ is simply a fantasy created by those envious of physics.”

Although imperfect biological systems produce noise, this noise can lead to beneficial variations that natural selection may target, notes Ganley.

The research team remains puzzled about a 25% increase in human DNA activity. “We still need to investigate the cause behind this finding,” Ganley states.

While some additional RNA generated might serve functional purposes, this does not diminish the overall perspective of junk DNA. Ongoing research is employing machine learning techniques to identify potentially meaningful activities amidst the noise.

The research team intends to publish their outcomes, though they have yet to complete their findings.

Pompeii’s Construction Site Unveils the Secrets of Roman Concrete Production

Ceramic roof tiles and tuff blocks uncovered at an ancient construction site in Pompeii

Pompeii Archaeological Park

A recently uncovered ancient building site in Pompeii, preserved since the eruption of Mount Vesuvius, has enabled archaeologists to finally understand the process behind Roman concrete production.

Located near Naples, Pompeii was entombed under layers of volcanic ash in 79 AD. Excavation efforts commenced in the 1880s but were halted until early 2023, when extensive new diggings began.

The latest excavations revealed a nearly intact concrete workshop, featuring inscriptions on the walls detailing work schedules and material quantities. Numerous concrete tools, heaps of quicklime, and salvaged roof tiles were also discovered.

Admija Masic of the MIT research team expressed amazement at the site’s remarkable preservation, stating it provides insights into Roman concrete techniques that “laboratory recreations simply cannot achieve.”

“The material was just as it was at the moment the eruption halted the city,” Masic mentioned. “Studying it felt as if I were transported back to 79 A.D., standing beside the workers mixing and pouring concrete.”

The team’s revelations indicate that established assumptions about Roman concrete production should be reconsidered.

Historical records suggest that Romans utilized slaked lime (calcium hydroxide) for concrete, combining it with water before mixing it with other components like volcanic ash.

Contrarily, chemical analyses of dry, premixed materials found in Pompeian workshops show that ancient builders actually employed a hot mixing technique using quicklime, or calcium oxide. This method involved combining the lime with all other ingredients including volcanic ash and minerals, before adding water, which was heated as a result of the chemical reaction, causing some concrete to set.

“Our findings demonstrate that quicklime was crucial to structural concrete,” Masic states. “In contrast, slaked lime was typically used for finish mortar and plaster, where a smooth surface and workability were paramount.”

The hot-mixing method offers the advantage of lime remnants, known as crusts, remaining in the concrete post-hardening, which can autonomously heal small cracks and defects.

“These lime fragments serve as reservoirs of calcium that can dissolve and recrystallize in crevices and fractures, or interact with volcanic ash to enhance the microstructure of the concrete,” Masić explains.

A modern concrete worker would easily understand the Roman concrete-making technique at Pompeii and could seamlessly transition into the workshop to start working, he states. “The chemistry is ancient, yet the technology is readily recognizable.”

Lava Tubes Hold Secrets of Unidentified ‘Microbial Dark Matter’ – Sciworthy

Mars’ surface is not currently conducive to human life. It presents extreme challenges, including a tenuous atmosphere, freezing temperatures, and heightened radiation levels. While Earth’s extremophiles can tackle some obstacles, they can’t handle them all simultaneously. If Martian life exists, how do these microbes manage to survive in such an environment?

The answer might lie within caves. Many researchers believe that ancient lava tubes on Mars formed billions of years ago when the planet was warmer and had liquid water. Caves serve as shelters against radiation and severe temperatures found on the Martian surface. They also host the nutrients and minerals necessary for sustaining life. Although scientists cannot yet explore Martian caves directly, they are examining analogous sites on Earth to establish parameters for searching for life on Mars.

A research team, led by C.B. Fishman from Georgetown University, investigated the microorganisms inhabiting the lava tubes of Mauna Loa, Hawaii, to learn about their survival mechanisms. Thanks to careful conservation efforts by Native Hawaiians, these lava tubes remain undisturbed by human activity. Researchers believe that both the rock structures in Mauna Loa Cave and the minerals formed from sulfur-rich gases bear similarities to Martian cave formations.

The team analyzed five samples from well-lit areas near the cave entrance, two from dimly lit zones with natural openings known as skylights, and five from the cave’s darkest recesses. Samples were chosen based on rock characteristics, including secondary minerals like calcite and gypsum, and primary iron-bearing minerals such as olivine and hematite.

Findings revealed significant variation in mineralogy within the cave, even over small distances. The bright samples were predominantly gypsum, while the dark samples lacked these key minerals. Instead, one dark sample was rich in iron-bearing minerals, while another contained mainly calcite, gypsum, and thenardite.

To identify the microorganisms within the samples, the team employed the 16S rRNA gene to recognize known microbes and understand their relationships. They also reconstructed complete genomes from cave samples using a method called metagenomic analysis. This technique is akin to following instructions to assemble various models from mixed DNA fragments. Such insights help researchers grasp how both known and unknown microorganisms thrive in their respective environments.

The team discovered that approximately 15% of the microbial genomes were unique to specific locations, with about 57% appearing in less than a quarter of the samples. Furthermore, microbial communities in dark regions exhibited less diversity and were more specialized compared to those in well-lit areas. While dark sites were not as varied as bright ones, each supported its own distinct microbial community.

To explain this difference, the researchers proposed that dark microbes have limited survival strategies since photosynthesis is impossible without light. Instead, these microbes extract chemical energy from rocks and decaying organic matter, much like how humans derive energy from breaking down food.

The findings from metagenomic data indicated that even though sulfur minerals were abundant, very few microorganisms specialized in sulfur consumption were present. This aligns with expectations in oxygen-rich environments, as oxygen tends to react with sulfur, making it unavailable to microorganisms. The researchers suggested that sulfur-metabolizing microbes may be more commonly found in low-oxygen environments, such as Mars.

Additionally, the study revealed that a majority of the microorganisms found in these caves were previously undescribed by science, contributing to what is referred to as microbial dark matter. The existence of such unknown microorganisms hints at novel survival strategies.

The research team concluded that lava tube caves could be a crucial source of new microorganisms, aiding astrobiologists in their quest to understand potential life forms on Mars. They recommended that future investigations into Martian caves should focus on detecting small-scale microbes in various mineral contexts. Over time, the interplay between cave conditions and Martian microorganisms may be unveiled as Mars becomes less habitable.

Skeleton ‘Pregnancy Test’ May Unlock Secrets of Ancient Maternal Lives

Skeleton of a woman holding a baby in her left arm, interred in an Anglo-Saxon cemetery in Screnby, England

Dr Hugh Wilmot, University of Sheffield

Researchers are now investigating ancient pregnancy tests undertaken on women from centuries past.

For the first time, scientists have identified levels of estrogen, progesterone, and testosterone in remains of women from the 1st to the 19th century. Some of these women were entombed with their unborn children. This revelation indicates that historic bones and teeth can retain identifiable traces of specific sex hormones, which might aid in discerning which individuals at archaeological sites were pregnant or had recently given birth at the time of their demise, according to Amy Barlow from the University of Sheffield, UK.

“The physiological and emotional impacts of pregnancy, miscarriage, and childbirth carry profound significance for women, yet they remain largely unexplored in archaeological records,” she notes. “This technique could revolutionize how we comprehend the reproductive narratives of ancient populations. We’re genuinely excited about it.”

Establishing pregnancy in ancient individuals can be challenging, particularly if the fetus lacks a visible skeleton. Even second- and third-trimester fetuses may be overlooked due to their bones resembling those of the mother’s hands, often placed on the abdomen during burial.

Contemporary pregnancy tests evaluate hormone levels such as hCG in blood or urine. However, hCG degrades rapidly, leaving minimal evidence in the body.

In contrast, progesterone, estrogen, and testosterone can persist in tissues for extended periods. Recent studies have demonstrated that these steroid hormones are also present in human blood, saliva, and hair. Samples from long-buried Egyptian mummies.

To explore the likelihood of identifying ancient pregnancies, Barlow and her team analyzed rib fragments and one neck bone from two men and seven women interred in four British cemeteries. They also examined teeth from another male.

Two of the women had fetal remains discovered within them, and another two were buried alongside their newborns. The gender of the others was established through DNA analysis.

The research team ground each sample into powder and employed chemical techniques to extract the steroid hormones. Laboratory tests subsequently identified the estrogen, progesterone, and testosterone levels in each of the 74 samples.

Estrogen was only found in four samples, without a discernible pattern. This may be due to its quicker breakdown compared to progesterone or testosterone, which may not accumulate as efficiently in tissues.

However, between the 11th and 14th centuries, heightened levels of progesterone were discovered in the spines of young women who died while carrying full-term fetuses. A later pregnant woman interred in the 18th or 19th century also exhibited elevated progesterone in her ribs. Moderate progesterone levels were noted in the dental plaque of two women buried with their infants during the 5th or 6th century.

Interestingly, no testosterone was detected in the bones or teeth of these four women. However, one woman who was buried with her premature infant had trace amounts of testosterone in her dental plaque. In contrast, three unrelated women from 8th- to 12th-century sites and Roman tombs showed testosterone in all layers of their ribs and teeth.

Low testosterone levels are known to play a crucial role in women’s health, so its discovery in these samples isn’t unexpected, Barlow states. “However, the absence of testosterone may indicate that she was recently or currently pregnant at the time of her death,” she adds.

“This intersection of archaeology and hormone science is exhilarating and unforeseen,” states Alexander Komninos from Imperial College London. “These methods will enhance our ability to detect pregnancy in human remains with greater precision, providing deeper insights into ancient pregnancies.”

Nevertheless, while the findings show promise, additional research is essential to clarify many aspects, according to Barlow. For instance, moderate progesterone levels were frequently found in the bones and inner teeth of men, but the reasoning behind this remains unclear, she comments. “Interpretation is quite cautious at this junction.”

Scientists Might Have Unraveled the Secrets of Teotihuacan’s Written Language

The civilization that thrived in Teotihuacan during the Classic period holds a distinctive position in Mesoamerican history. Today, it continues to represent Mexico’s rich heritage and is among the most frequented archaeological locations in the Americas. However, inquisitive tourists often find that the ethnic and linguistic connections of the Teotihuacanos are still a mystery. While the deciphering of other Mesoamerican writing systems has unveiled significant insights about dynasties and historical occurrences, researchers have yet to extract information about Teotihuacan society from their own written artifacts. The topic of writing in Teotihuacan indeed provokes several intriguing questions. Do the symbols depicted in the images of Teotihuacan represent a form of writing? If they do, what was their purpose? Were they created to be understood irrespective of language? If they indicated a specific language, which one was it? Researchers Magnus Pharaoh Hansen and Christopher Helmke from the University of Copenhagen suggest that Teotihuacan writing shares fundamental characteristics with other Mesoamerican writing systems, including the utilization of logograms based on rebus principles and a technique termed “double spelling.” They contend that it encapsulates a specific, identifiable language: Uto-Aztecan, the direct predecessor of Nahuatl, Chora, and Huichol, and they offer a new interpretation of certain Teotihuacan glyphs.

Teotihuacan is a revered pre-Columbian city established around 100 BC and thrived until 600 AD.

This ancient metropolis, situated in the northeastern area of the Basin of Mexico, expanded over 20 square kilometers and housed up to 125,000 residents while engaging with other Mesoamerican cultures.

The identities of Teotihuacan’s builders and their relationships to subsequent populations remain uncertain. The reasons behind the city’s abandonment also spark debate, with theories ranging from foreign invasion, civil strife, ecological disaster, or a combination of these factors.

“There are numerous distinct cultures in Mexico, some linked to specific archaeological traditions, while others remain ambiguous. Teotihuacan exemplifies such a case,” stated Dr. Pharaoh Hansen.

“The languages they spoke and their links to later cultures are still unknown.”

“One can easily identify the Teotihuacan culture when compared to modern cultures,” added Dr. Helmke.

“For instance, the remains of Teotihuacan suggest that parts of the city were occupied by the more widely recognized Maya civilization.”

The ancient inhabitants of Teotihuacan left a collection of symbols, primarily through wall murals and decorative ceramics.

For years, researchers have debated whether these symbols represent an actual written language.

The authors assert that the inscriptions on Teotihuacan’s walls indeed record a language that is a linguistic precursor to Cora, Huichol, and the Aztec language Nahuatl.

The Aztecs, well-known in Mexican history, were thought to have migrated to central Mexico following the decline of Teotihuacan.

However, researchers claim there are linguistic connections between Teotihuacan and the Aztecs, indicating that Nahuatl-speaking peoples might have settled in the region much earlier and are in fact direct descendants of Teotihuacan’s original population.

To elucidate the linguistic parallels between Teotihuacan’s language and other Mesoamerican tongues, scientists have been working to reconstruct a much older version of Nahuatl.

“Otherwise, it would be akin to interpreting the runes on a famous Danish runestone, like the Jellingstone, using contemporary Danish. That would be an anachronism. We must attempt to read the text with a more temporally appropriate language,” explains Dr. Helmke.

Examples of logograms that make up the Teotihuacan written language. Image credit: Christophe Helmke, University of Copenhagen.

The script of Teotihuacan presents significant challenges for decipherment due to multiple factors.

One challenge is that the logograms may possess a direct semantic meaning; for instance, an image depicting a coyote directly translates to “coyote.”

In other instances, symbols must be interpreted in a rebus format, wherein the sounds represented by the depicted objects are combined to form words; however, such words are often conceptual and difficult to express as single figurative logograms.

This complexity underscores the necessity for a solid understanding of both the Teotihuacan writing system and the Uto-Aztecan language that researchers believe is encoded in the inscriptions.

To unlock the Teotihuacan linguistic riddle, one must be aware of how words were pronounced at that time.

This is why the researchers are focusing on various aspects concurrently. They are reconstructing the Uto-Aztecan language, a formidable challenge in its own right, while applying this ancient language to interpret the Teotihuacan texts.

“In Teotihuacan, pottery with inscriptions continues to be unearthed, and we anticipate that many more wall paintings will be discovered in the future,” remarked Dr. Pharaoh Hansen.

“The scarcity of additional text clearly hampers our study.”

“It would be beneficial to find the same symbol used similarly in varied contexts.”

“This would further substantiate our hypothesis, but for now, we are limited to the documentation available to us.”

Dr. Pharaoh Hansen and Dr. Helmke are enthusiastic about their recent advancements.

“Prior to our work, no one had applied a linguistically appropriate approach to deciphering this written form,” stated Dr. Pharaoh Hansen.

“Moreover, no one had successfully established that a particular logogram could hold phonetic significance applicable in contexts beyond its primary meaning.”

“Through this process, we have developed a method that can serve as a foundation for others to broaden their comprehension of the texts.”

The team’s study has been published in the journal Current Anthropology.

New Research Uncovers the Secrets of Burgess Shale Trilobites

Appendages of arthropods serve various functions, including feeding, locomotion, and reproduction. Fossils dating back to the Cambrian period (539-487 million years ago) provide remarkable details of extinct arthropod appendages, enhancing our understanding of their anatomy and ecological roles. However, due to the limited number of fossils and often incomplete preservation, studies on appendage functions typically depend on idealized reconstructions. This new research focuses on the paleontological species Olenoides serratus, a prolific trilobite from the Cambrian Burgess Shale, noteworthy for its numerous well-preserved specimens featuring soft tissue that allow for a detailed analysis of appendage functionality.

Situated in British Columbia, Canada, the Burgess Shale is renowned for its exceptional fossil preservation, including soft tissues such as limbs and internal organs.

While trilobites are common in fossil records, their soft limbs are seldom preserved due to their hard exoskeleton, leading to a limited understanding of these structures.

The trilobite species Olenoides serratus offers a unique chance to investigate these appendages further.

Harvard paleontologist Sarah Ross and her team examined 156 limbs from 28 fossil specimens of Olenoides serratus to reconstruct the precise movements and functions of these ancient arthropod appendages, shedding light on one of the earliest successful aquatic animals.

“Understanding the behavior and movement of fossils poses challenges, as we cannot observe their activities like we do with living organisms,” stated Dr. Ross.

“Instead, we meticulously analyzed the morphology of numerous specimens while also utilizing modern analogues to infer how these ancient creatures lived.”

The researchers also assessed the range of motion of the legs of living horseshoe crab species Limulus polyphemus.

“Arthropods possess articulated legs composed of multiple segments that can flex upwards or downwards,” they noted.

“The range of motion is influenced by the specific directional capabilities of each joint.”

“This range, combined with the limbs’ shape and segment configuration, determines how the animal utilizes its appendages for walking, grasping, and burrowing.”

Horseshoe crabs, commonly found along the eastern coast of North America, are compared with trilobites due to their analogous behaviors.

“Despite their close relation to spiders and scorpions, horseshoe crabs are part of a different branch of the arthropod tree, whereas trilobite relationships remain ambiguous.”

The comparison arises from both animals’ adaptation of articulated limbs for navigating the seafloor.

However, the findings revealed that their similarities were minimal.

In contrast to horseshoe crabs, characterized by specialized limb joints for bending and expanding—facilitating feeding and protection—Olenoides serratus exhibited a simpler yet highly functional limb structure.

“We found that the limbs of Olenoides serratus had minimal extension, primarily far from the body,” Dr. Ross explained.

“Their limbs functioned differently than those of horseshoe crabs. Olenoides serratus could walk, dig, bring food to their mouths, and even elevate their bodies above the seafloor.”

To realize these findings, the scientists constructed advanced 3D digital models based on hundreds of fossil images captured from various angles.

Since trilobite limbs are often crushed and flattened, reconstructing them in three dimensions presents a significant challenge.

“We depend on exceptionally well-preserved specimens, comparing limb structures from multiple angles while leveraging related fossils to fill in any missing details,” said Professor Javier Ortega-Hernandez of Harvard University.

The team correlated the morphology of trace fossils to the movements of the limbs.

“The different movements of Olenoides serratus could create trace fossils with varying depths,” Dr. Ross elaborated.

“They were capable of raising their bodies on deposits, allowing them to traverse obstacles and navigate efficiently through swift currents.”

Remarkably, the researchers found that males possessed specialized appendages for mating, and each leg featured gills for respiration.

The findings were published in the journal BMC Biology on August 4th, 2025.

Archaeologists Reveal the Hidden Secrets of Pompeii’s Vibrant Legacy

When Mount Vesuvius erupted in 79 AD, it buried Pompeii under a meter of ash and pumice, effectively freezing the Roman city in time. However, a new study reveals that the story didn’t end there. Life persisted for centuries, emerging among the abandoned structures in significantly altered forms.

Recent findings from restoration efforts in the city’s southern quarter indicate that Pompeii was reoccupied shortly after the eruption and remained inhabited until at least the fifth century.

“Researchers and archaeologists have always been intrigued by the idea of people returning to Pompeii, but this was often overshadowed by a focus on the remarkably preserved artwork from before 79 AD,” said Gabriel Zuchtliegel, director of Pompeii Archaeological Park and lead author of the new study, in an interview with BBC Science Focus.

However, the resettlement was a shadow of Pompeii’s former self. “The reoccupation of Pompeii was not comparable to the city as it existed before AD 79,” Zuchtliegel stated.

“It resembled more of a slum—a highly unstable and unstructured settlement. As far as we know, there were no temples or public buildings.”

Families fashioned makeshift homes on the remaining upper floors of the buried buildings, while the lower levels (previously above ground) were transformed into hearths and caves, complete with ovens and small workshops.

But who chose to return to the devastated city? According to Zuchtliegel, these residents were likely those with limited options. “Certainly, they would have preferred to live elsewhere if possible, but some may not have had other resources.”

There was also an additional motivation: the opportunity to reclaim treasures buried beneath the ash. “A vast amount of wealth lay hidden underground, including metals, statues, coins, and marble,” Zuchtliegel noted.

“People may have initially returned to unearth the ruins of Pompeii… over time, vegetation would have reclaimed the land, creating a green and thriving landscape.”

This fragile community endured for centuries. Alongside the broader decline of the Western Roman Empire, it likely ceased to exist after another eruption in 472 AD. “There may have been general demographic declines, migration, and hardships related to the collapse of centralized governance,” Zuchtliegel explained.

“It’s astonishing to see how people endure and cope in such extreme circumstances.”

“Fresh Beginnings at 60: Sharing My Old Diary Online and Discovering My Youthful Secrets Went Viral”

b
Etsy Lerner may not view herself as a TikTok star, but the New York Times labels her as one, even calling her an influencer. To her, it signifies payment and illicit goods — all she possesses is a free pen. “I genuinely do it for myself,” she states, “and for those who follow me.”

Lerner is 64 years young. She spent over two decades as a literary agent, representing authors like Patti Smith and Temple Grandin. A non-fiction writer, she is the author of her debut novels, “The Shred Sisters” and “Love Letter to Loneliness.” However, her TikTok presence is noteworthy, boasting 1.5 million followers! There, she shares videos reading from a diary chronicling her chaotic 20s.

“I don’t know who you love, who loves you, what you do for your job, what your purpose is,” she expresses in one post. “This morning I stumbled upon a line in my journal. In my 20s, I wrote: ‘I feel like I don’t know who I am.'”

Lerner shares posts while in a dressing gown and without makeup. Initially, she ventured into BookTok to support authors, but as her new novel was approaching release, she started filming herself on camera, despite not initially gaining followers. “A friend advised me to embrace it like my own TV channel… so I thought, ‘I’ll read from an old diary.'”

She has kept journals since the age of 11, inspired by Anne Frank’s “The Diary of a Young Girl.” “I penned my first poem there, trying to understand myself…” Although her journal from ages 12 to 18 was lost when her car was stolen, she has roughly 30 volumes from her 20s safely stored away in her attic.

“My journals are incredibly melancholic. They discuss loneliness, the search for love and friendship, and the quest for identity,” she reflects.

Lerner describes herself as a “slow bloomer.” Accepted into Columbia’s MFA Poetry Program at 26, she entered the publishing world in her late 20s, a time when most editorial assistants were fresh college graduates. “I didn’t experience love until I was 30 and lacked any significant relationships… I lost much of my teens and endured depression through most of my 20s.”




“It’s all about connecting and trying to communicate,” … Betsy Lerner captured in New Haven, Connecticut.

At 15, her parents took her to a psychiatrist, which led to a diagnosis of bipolar disorder. “I resisted accepting that I had this condition. I fought against it for a long time,” she admits. Her 2003 memoir, Food and Loathing, recounts her relationship with weight, food, and depression, detailing one instance in her late 20s when she found herself standing on a bridge over the Hudson River.

A breakthrough occurred at 30 when she connected with a psychopharmacologist who could prescribe the right dosage of lithium (they have collaborated for 35 years). She also got married.

Writing in her journal became less frequent. While she initially wrote at night in bed, “I wasn’t feeling so sad and lonely anymore,” she reflects.

Over the years, Lerner says, “I was instinctively drawn to strength.” Currently, she prioritizes stability above all else.

She had no intentions of writing a novel. Nevertheless, in 2019, she faced “the tragic loss of four” individuals: her mother, two teenagers, Ruby and Hart Campbell, who were tragically killed by a drunk driver, and her best friend, author George Hodgman, who died by suicide. “I still grapple with the idea of grieving everyone, all the time,” she shares.

Following these losses, she began writing “Shred Sisters.” The novel serves as a means for her and her two sisters to care for one another while navigating their grief. She has also written another novel and continues to share insights from her diary as long as inspiration strikes. “It’s all about connecting and communicating,” she affirms.

“There’s a constant flow of comments from young adults in their 20s who resonate with my struggles. That connection motivates me immensely. I feel aligned with these young individuals.”

Genetics Unveils the Secrets Behind Potato Origins

Potato tubers are a product of ancient hybridization events

Jackie Bale/Getty Images

The common potato has been discovered to originate from a cross between the ancient tomato and a lesser-known South American lineage called Etuverosam.

Plants from the Etuverosam group resemble potato plants but lack one significant feature: they do not yield the starch-rich tubers that make cultivated potatoes a vital food source globally.

Sandra Knapp from The Natural History Museum in London and her team examined the genetics of three groups within the Solanum genus: Petota, which includes 107 species of cultivated potatoes, alongside 17 tomato types and three Etuverosam species. All three groups are believed to have diverged from a shared ancestor roughly 14 million years ago.

The researchers analyzed 450 genomes from cultivated potatoes and 56 wild potato species, revealing a consistent genetic mixture of tomato and Etuverosam genes across all samples.

Findings suggest that the origins of potato strains result from hybridization events with tomato ancestors, likely from a lineage situated in present-day Chile, dating back about 8 million years.

These hybridization events have led to novel gene combinations and innovations like tuber formation. “This process facilitates gene sharing, enabling new strains to produce tubers and helping these plants to thrive in newly formed, cold and arid environments,” Knapp explains.

This indicates that hybridization acts as “a significant driver of diversity evolution,” according to Knapp.

“While the edible parts of tomatoes and potatoes appear quite different, the actual plants are remarkably similar,” she elaborates. “If you happen to find a potato plant that produces fruit, it will yield green, tomato-like berries, but these are inedible and taste unpleasant.”

Brett Summerrell from a Botanical Garden in Sydney, Australia, which did not participate in the study, mentions that this new research offers substantial evidence of hybridization and resultant species diversification.

“This study underscores the necessity of understanding the evolutionary importance of crops and safeguarding their wild relatives, which may be crucial for addressing future agricultural challenges,” Summerrell emphasizes.

“Many relatives of potato-like species face threats posed by habitat destruction and climate change.”

Patient Rover Could Uncover Secrets of Newly Discovered Mars Volcano

The questionable volcano (highlighted) is located near the prominent Jezero crater on Mars

NASA/JPL/MSSS/JHUAPL/ESA/DLR/FU BERLIN/ASTER COWART

Recent observations suggest the existence of a volcanic formation at the edge of Mars’ Jezero Crater, currently under investigation by NASA’s rover. This rover might already be collecting samples from materials expelled during an ancient volcanic eruption.

Perseverance, which landed in Jezero Crater in 2021, is methodically moving toward the western edge, tracing an ancient river that is believed to have flowed between 300 million and 4 billion years ago.

The rover is gathering samples meant to be returned to Earth as part of the Mars Sample Return mission planned for the 2030s. However, this endeavor faces potential cuts proposed by the Trump administration affecting NASA’s funding.

Some of the materials in the samples were thought to be volcanic, showcasing characteristics of lava flow. Recently, James Ray from Georgia Tech in Atlanta and his team have identified a possible volcanic structure at Jezero Mons—a dormant volcano situated on the southeastern edge of Jezero.

High-resolution images from Martian orbiters have revealed fine-grained materials in the vicinity, possibly indicating ash from the volcano. The dimensions and shape of Jezero Mons—21 km wide and 2 km high—parallel those of similar volcanoes on Earth.

“The evidence for igneous volcanoes is most consistent with our observations,” states Ray, noting that magma may have originated from beneath the surface. “This is the strongest case we can make without physically visiting the site.”

By analyzing the craters near the volcano, Ray and his colleagues estimate that Jezero Mons may have last erupted around a billion years ago.

This finding suggests that the rover might have collected volcanic samples. If they can be returned to Earth, scientists would be able to accurately date volcanic activity on another planet for the first time.

“Knowing when that volcano was active is incredibly exciting,” exclaimed Briony Hogan from Purdue University in Indiana, a member of the rover’s science team. This information could significantly enhance our understanding of “how the interiors of planets evolve over time,” she adds.

Ideally, Ray mentions that he hopes to direct Perseverance to the volcano itself, but acknowledges this may not be feasible. “There are really fascinating ancient rocks to the west of the crater, so they’re likely driving in the opposite direction,” he explains. “I can’t blame them.”

Unraveling the Secrets of Lightning: A Possible Resolution Awaits

In the early days of scientific exploration, researchers observed natural phenomena and began to unravel the mysteries behind how lightning forms.

These brief yet incredibly bright bursts of radiation, referred to as Terrestrial Gamma Ray Flashes (TGF), were identified by a research team at Osaka University in Japan during a lightning event.

Interestingly, TGFs are typically observed in space, associated with supernovae and black hole jets. This raises the question: how does lightning produce the energy required to generate them?

Recent papers published in the journal Advances in Science potentially provide answers. While scientists previously believed that TGFs were caused by the rapid acceleration of electrons, testing this theory has proven challenging. The radiation often occurs in the final microsecond and is concealed by cloud cover.

This is why researchers involved in the new study employed innovative techniques to observe thunderstorms, utilizing a multi-sensor system that includes optical, radio frequency, and high-energy radiation sensors.

“The multi-sensor observations conducted here are unprecedented,” stated Dr. Harufumi Tsuchiya, the senior author of the paper. “While some mysteries persist, this approach has significantly deepened our understanding of these intriguing radiation burst mechanisms.”

So, what did they find? Collectively, the sensors unveiled two channels of charged particles known as the discharge pathway—one descending from the thundercloud to the TV tower, and the other ascending from the tower.

The scientists observed the formation of TGFs occurring 31 microseconds before the two pathways converged, resulting in a highly concentrated electric field where electrons accelerated at nearly the speed of light.

Once the two pathways merged, the burst continued for an additional 20 microseconds, yielding a lightning strike of -56 kiloamperes. (Don’t let the negative sign confuse you—it merely indicates the direction from cloud to ground. This current is exceptionally high, typical of lightning.)

Wada Yutaka, the lead author of the study, remarked, “The opportunity to examine extreme processes such as TGFs stemming from lightning enhances our understanding of the high-energy dynamics present in Earth’s atmosphere.”

Avoiding Taxes in Ancient Rome: Secrets Revealed in 1,900-Year-Old Papyrus Scrolls

In what wasn’t exactly the tax evasion trial of the century – given that it took place in the second century – the charges faced by the defendants were so weighty that they included forgery, financial fraud, and fraudulent slave sales. While tax evasion is an age-old practice, these particular crimes were deemed extremely serious under Roman law, with penalties ranging from hefty fines and lifelong exile to grueling labor and, in the most severe cases, being devoured by wild animals in a practice known as damnatio ad bestias.

The details of the allegations were recorded on papyrus, which was discovered decades ago in the Judean Desert and recently subjected to analysis. The documentation includes preliminary notes for the prosecutor and hastily drafted minutes from the judicial hearings. According to the ancient records, the tax evasion schemes involved document tampering, illicit slave sales, and manumission.

The accused in both tax cases were men. One of them, Gadalius, was the son of a poor notary who had ties to the local administrative elite. In addition to convictions for extortion and forgery, his extensive list of transgressions included banditry, incitement, and four appearances in court for tax evasion before the Roman governor. Gadalius’s partner in crime was a certain Saurus, identified as his “friends and collaborators,” and the mastermind Caper. While the ethnicity of the accused is not explicitly mentioned, their Jewish background is inferred from their biblical names Gedaliah and Saul.

This ancient legal saga unfolded during the reign of Hadrian, around the year 130 AD or possibly before 132 AD when Simon Bar Kochiba, the leader of the Messianic rebels, launched a large-scale uprising, marking the third and final conflict between the Jewish people and the Empire. The rebellion was brutally suppressed, resulting in hundreds of thousands of casualties, mass expulsions of Jewish communities, and the renaming of Syria and Palestine by Hadrian.

Anna Dolganov, a historian of the Roman Empire at the Austrian Archaeological Institute who deciphered the scroll, remarked, “The papyrus sheds light on the Roman authorities’ suspicion of their Jewish subjects.” She pointed out that there is archaeological evidence of a coordinated effort during the Bar Kochiba rebellion. “It is plausible that individuals like Gadalia and Saurus, who sought to subvert Roman rule through tax evasion, were involved in the uprising’s planning,” Dr. Dolganov suggested.

In the latest edition of Tyche, an ancient journal published by the University of Vienna, Dr. Dolganov and three colleagues from Austria and Israel present court proceedings as case studies. Their research unveils how Roman institutions and imperial law influenced the administration of justice in an environment with relatively few Roman citizens.

“This document provides intriguing and valuable insights into the slave trade in this region of the empire,” noted Dennis P. Kehoe, a classicist at Tulane University not involved in the study. “The allegations may involve the Jews owning slaves.”

The exact date and location of the papyrus’s discovery remain uncertain, but Dr. Dolganov suggested it was found by an ancient Bedouin dealer in the 1950s. She suspected Nahal Haver, a steep canyon west of the Dead Sea where Bar Kochiba rebels sought refuge in a cave hid along the natural fault line of a limestone cliff. In 1960, archaeologists unearthed documents from the era in one of the Jewish hideouts, with more discoveries made since then.

A 133-line irregular scroll, initially misclassified, went unnoticed in the Israeli Antiquities Authority archives until 2014 when Hannah Cotton Parietl, a classicist at the Hebrew University of Jerusalem, identified it as being written in ancient Greek. Given the complexity and exceptional length of the document, a team of scholars was assembled to conduct detailed physical examinations and cross-referencing with historical sources.

Deciphering the papyrus and piecing together its intricate narrative posed a significant challenge for Dr. Dolganov. “The text features small, densely packed letters and highly rhetorical Greek replete with technical legal terminology,” she remarked. Unlike more straightforward documents such as contracts, there were no standardized templates for translation ease. “The fact that we only have the latter half of the original text further complicates matters,” Dr. Dolganov added.

Researchers speculated that the tax evasion scheme aimed to circumvent official scrutiny. This necessitated meticulous detective work to decipher the sequence of events. “I had to adopt the Roman fiscal authorities’ perspective to grasp the text’s nuances,” Dr. Dolganov explained. She also had to step into the accused’s shoes to understand the rationale behind tax fraud in the remote fringes of the Roman world.

The ancient stratagems resonate with contemporary tax experts. A German legal expert relayed to Dr. Dolganov that the subterfuges of Gadalius and Saurus mirrored present-day practices of tax evasion, such as asset shifting and fictitious transactions. The Roman interrogation methods aligned closely with modern-day investigative custody for financial crimes, marked by intimidation and frequently rigorous questioning.

A Princeton University classicist unaffiliated with the project, Brent Shaw, remarked:

The cases against Gadalius and Saurus were bolstered by intelligence provided by informants who betrayed them to the Roman authorities. Interestingly, the text implies that the informer might have been none other than Saurus himself, who implicated his partners to shield himself from an imminent financial scrutiny. The most plausible scenario posits that Saurus, a Jewish resident, orchestrated the pseudo-sale of several slaves to Chareas, a neighbor residing in the adjacent Arabian province, as per Dr. Dolganov’s interpretation.

By selling slaves across provincial borders, Saurus sought to obfuscate assets from scrutiny. While physically present in Saurus’s custody, the slaves, undocumented in Arabia, evaded declaration by Chareas. “Effectively, the slaves vanished on paper from Judea and never materialized in Arabia, eluding Roman oversight,” Dr. Dolganov noted. “This ensured that no further taxes were levied on these slaves.”

The Empire implemented a sophisticated system for monitoring slave ownership and collecting various levies, including a 4% tax on slave sales and a 5% duty on estates. “To emancipate empire-owned slaves, detailed documentary evidence of current and prior ownership was mandatory,” Dr. Dolganov elucidated. “Any missing or dubious documents would trigger an inquiry by Roman administrators.”

In an attempt to conceal Saurus’s double-dealings, Gadalius, the son of a notary, allegedly fabricated bills of sale and other legal documents. When authorities detected irregularities, the defendant purportedly bribed the local municipal council for protection. During the trial, Gadalius shifted blame onto his deceased father for the forgeries, while Saurus implicated Chaireas in the document tampering. The papyrus does not provide insights into their motives. “The rationale behind men risking forgery to liberate slaves without legitimate documentation remains a mystery,” Dr. Dolganov mused.

One conjecture posits that by orchestrating fake slave sales followed by manumission, Gadalis and Saurus may have been adhering to a Jewish religious mandate to free those enslaved. Alternatively, there might have been a profit incentive in capturing individuals across borders, potentially entrenching them as free Romans after freeing them from “enslavement.” Or Gadalia and Saurus might have engaged in human trafficking, a possibility that is as speculative as it is fraught with implications, Dr. Dolganov emphasized.

One aspect of the trial that struck Dr. Dolganov was the prosecutor’s professionalism. Employing sophisticated rhetorical strategies reminiscent of Cicero and Quintilian, the prosecutor exhibited a mastery of Roman legal terminology and concepts in Greek. “Here, on the edge of the Roman Empire, we witness a highly skilled legal practitioner steeped in Roman law,” Dr. Dolganov remarked.

The papyrus does not reveal the final verdict. “If a Roman judge deemed these men as incorrigible criminals deserving execution, Gadalius, as a member of the local elite, might have met a more merciful end through decapitation,” Dr. Dolganov suggested. “In any case, it beats being torn apart by a leopard.”

Surprising Furry Secrets Hidden within Mystical Medieval Book Covers

Medieval scribes fill a volume called veterinarians with illustrations and descriptions of fantastic creatures. Manuscripts containing representations of these animals also relied on the beast zoo. These and other volume covers were made from calf, goat, sheep, deer and pig skins.

Most of these skins were removed before they were converted to book bindings. However, the medieval manuscript sets in northeastern France have a distinctive finish. The weathered cover is covered with hair.

Matthew Collins, a biofactorologist at the University of Copenhagen and Cambridge and author of the new study, said: However, it turns out to be difficult to pinpoint the source of hairy leather.

These furry books appear to be at home at the Hogwarts Library, but were originally written by Clairvaux Abbey, a hub of the Cistercians, the orders of the Catholic monk Ks. Founded in the Champagne Adennes region of France in 1115, the monastery was located in one of the largest monastery libraries in medieval Europe.

Approximately 1,450 volumes of the monastery’s extensive corpus survive. Approximately half of these manuscripts remain in the original, fragile bindings. Many were tied in Romanesque style in the 12th and 13th centuries, parchment was placed between wooden boards fixed with thread and cord.

At Clairvaux Abbey, these Romanesque books were often housed in secondary covers, bristled with fur. Traditionally, this creepy leather was thought to be made from wild boars and deer. However, the hair follicles of some manuscripts do not match the fur of either mammal.

Dr. Collins and his colleagues examined the hairy covers of 16 manuscripts once housed at Clairebaud Abbey. Researchers rubbed the sides of the leather meat with an eraser and carefully removed the crumb-sized sample. We then used various techniques to analyze the protein sequences and bits of the ancient DNA of leather.

Their findings published in the journal on Wednesday Royal Society Open Sciencereveals that the book is tied to seal skins, not to local land mammal skins. Some books are tied up in the skin of harbor seals, and at least one came from harp seals. Comparing them to modern DNA suggests that the origins of Scandinavian and Scottish seals, or as far as Iceland and Greenland.

These different territories were once connected by complex medieval trading networks. During the Middle Ages, Scandinavian traders harvested walrus ivory and fur from Greenland and sent them to mainland Europe. Clairebaud and his monks were far more inland from these coastal front posts, but the monastery was near a trafficked trade route.

The discoveries shed light on medieval society, according to Mary Wellesley, a fellow at the London Institute of Historical Studies, who specializes in medieval manuscripts and was not involved in new papers.

“The small details of the manuscript can tell you a lot about the world that created them,” Dr. Wellesley said. “It’s a common assumption that people didn’t move around, but these monasteries are part of this incredible network of goods, books and ideas.”

Seals were a valuable product for meat, dull, waterproof skin. This could be made into boots or gloves. Some records even claim that Sealskin was used to pay church taxes. Coastal communities in Scandinavian and Ireland used Sealskin to bind books, but this practice was far more unusual in the mainland Europe.

However, Cistercian monks apparently liked Sealskin’s books. Examples of these furry manuscripts have been found in other Abbeys, descendants of Clairevaux. These monks used this material to combine the most important documents, including historical information about the Cistercians, historical information about St. Bernard.

According to Dr. Collins, the fur color of the seal may explain the preference of the monks for using animal skins. The cover of the manuscript is now yellowish-gray or spotted brown, but was once wrapped in the white fur of a seal puppy. This shade matched the best of the monks’ dissatisfaction.

“In medieval Europe, you really don’t have anything white or white,” said Dr. Collins. “It must have been very magical.”

The seal itself appears to resemble the magical entity of the monk ks. In medieval veterinarians, seals are labelled “sea calves,” resembling dogs that have raised fish tails.

TikTok’s Money-Making Secrets: How Kids’ Live Streams Generate Revenue

Three young children huddle in front of the camera, nibbling and fidgeting. “Support us. We are extremely poor,” the boy says, gazing into the lens.

They appear to be in a mud brick hut in Afghanistan, experiencing severe poverty. Despite this, their live broadcasts have reached audiences in the UK and worldwide through Tiktok Live.

They spend hours soliciting virtual “gifts” that can later be exchanged for money. When they receive a gift, they politely applaud. In one live stream, a girl jumps up and exclaims, “Thank you, we love you!” After receiving a digital rose from a woman in the US, which costs approximately 1p on Tiktok, when converted to cash, it’s worth less than a third of a penny.

Tiktok claims to prohibit child begging and other forms of exploitation, deeming it exploitative, and states that there is a strict policy for users participating in live shows.

However, research by Observer has revealed widespread practices of begging on live streams, actively promoted by algorithms and benefiting Tiktok, which takes up to 70% of fees and charges.

Olivier de Schutter, the United Nations Special Rapporteur on Extreme Poverty and Human Rights, has criticized this trend as “a shocking development,” accusing Tiktok and its intermediaries of profiting from people’s misery. He urges Tiktok to take immediate action, implement stringent policies against exploitative begging, and scrutinize the individuals profiting from the world’s most vulnerable.

“We have put a lot of effort into saving you,” said Jeffrey Demarco, a Digital Rights expert at Save the Children. “Documented practices reveal serious abuses that require immediate action to ensure the platform no longer allows or benefits from such content.”

An analysis conducted between January and April 2025 found evidence of live begging and related behaviors in countries like Indonesia, Pakistan, Afghanistan, Syria, Egypt, and Kenya.

Many live streams show families begging in domestic settings, while some streams seem to involve organized begging activities.

Apple’s UK Legal Challenge on Cryptography: Secrets Unveiled in Closed Room

The legal battle between the US tech company and the UK government over access to customer data saw a closed-door hearing on Friday after the press was unable to enter the courtroom for the lawsuit.

Apple has appealed to the Investigation Power Court after the Home Office requested access to encrypted data stored on Apple’s cloud servers.

British media outlets such as The Guardian, The BBC, The Financial Times, and Computer Weekly tried to gain access to the court for public interest reasons but were denied entry.

The government’s representative in the case, Sir James Eady KC, was seen entering the court on Friday.

Apple is contesting technical capacity notices issued under the Investigation Powers Act, which require assistance from businesses in providing evidence to law enforcement. The notice requested access to Apple’s Advanced Data Protection (ADP) service, which encrypts personal data stored remotely on a server.

Apple refused to comply with the order and challenged it in court, raising concerns about the legality of the national intelligence agency’s actions. Apple also pulled ADP from the UK, stating they have never created backdoor keys or master keys for their products or services.

ADP employs end-to-end encryption, ensuring that only the account owner can decrypt the data. Messaging services like iMessage and FaceTime are also end-to-end encrypted by default.

The government’s legal demands, known as Technical Capacity Notices, prohibit recipients from disclosing the order unless authorized by the Secretary of the Interior. Court hearings are supposed to be closed to the public only if strictly necessary to protect national security.

A bipartisan group of US lawmakers called for transparency regarding the UK government’s orders and urged further hearings and proceedings to shed light on the issue.

Reports suggest that British officials have started discussions with US counterparts to ensure that they are not seeking blanket access to US data, only information related to serious crimes like terrorism and child sexual abuse.

The Home Office has been contacted for comment.

UAV Technology Reveals Hidden Secrets of Ancient Mega-Fortress in Southern Georgia

High-resolution UAV-based aerial survey of the massive Bronze Age fortress Domanissis Gora in Georgia, South Caucasus, reveals the extent of a large external fortification system and settlements that are largely undocumented in the region. The exceptional size of D. gora helps add a new dimension to population assembly models in Eurasia and other regions.

Fortified settlements in the South Caucasus appeared between 1500 and 500 BC and represent an unprecedented development in the region’s prehistory.

Located on the border between Europe, the Eurasian steppe and the Middle East, the Caucasus region has a long history as a crossroads of cultures with a unique regional identity.

In a new study, archaeologists focused on Domanisis Gora, a 60-80 hectare fortified settlement in Georgia that is exceptional in its preservation and size.

Dr. Nathaniel Erb Satullo of the Cranfield Institute of Forensic Sciences at Cranfield University and his colleagues wrote: “The fortifications of Domanisis Gora consisted of a double-walled fortified core and a much larger outer shell with additional fortifications. “There is,” he said.

“Two steep-sided gorges, 60 meters deep in places, supplement the defensive walls.”

“Previous research had noted that the site had an unusually large walled enclosure, but the site had not been systematically mapped.”

The researchers used the DJI Phantom 4 RTK drone, which can provide less than 2 cm relative position accuracy and very high-resolution aerial imagery.

To obtain high-precision maps containing man-made features, each feature in the aerial images was carefully checked to confirm its identity.

To understand how the landscape at the site has evolved, the orthophotos were compared to 50-year-old photos taken by a Cold War-era reconnaissance satellite that was declassified in 2013.

This gave scientists much-needed insight into which features are recent and which are old.

The team was also able to assess which areas of the ancient settlement were damaged by modern agriculture.

All of these data sets were integrated into geographic information system (GIS) software to help identify patterns and changes in the landscape.

“The drone takes approximately 11,000 photos and uses advanced software to combine these photos with a high-resolution digital elevation model and orthophotos, which show every point as if looking directly down. We created a composite photo,” said Dr. Elvusaturo.

The researchers found that the Domanisis Gora ruins were more than 40 times larger than originally thought, and included a large outer settlement protected by a kilometer-long wall.

“Using a drone, we were able to understand the importance of the site and document it in a way that would not be possible on the ground,” said Dr. Herv Saturo.

“Domanisis Gora is not only an important discovery for the South Caucasus region, but also has broader significance for the diversity of large-scale settlement structures and their formation processes.”

“We hypothesize that Domanicis gora may have expanded through interaction with mobile pastoral groups, with large settlements outside it expanding and contracting seasonally.”

“The site has now been extensively mapped and further research will be initiated to gain insight into areas such as population density and density, livestock movements and agricultural practices.”

The team’s paper was published in a magazine ancient.

UFOs: Uncovering the Secrets the US Government is Keeping

On November 13, 2024, four witnesses appeared before the Joint Subcommittee. US Congressional Oversight and Accountability for a testimony session on so-called “Unidentified Anomalous Phenomena (UAP).” This is a necessary rebranding of the term “UFO.” The people who spouted these three letters in the past were rarely seen as trustworthy or worthy of testifying before the U.S. government.

The four witnesses were Rear Adm. Tim Gallaudet, former commander of the U.S. Navy’s Meteorological and Marine Command; Luis Elizondo, former director of the Defense Department’s Advanced Aerospace Threat Identification Program; investigative journalist Michael Shellenberger; Former NASA Deputy Administrator Michael Gold.

4 people submitted written testimony before the hearing. Shellenberger also allegedly original document An anonymous whistleblower report regarding a program called “Immaculate Constellation,” an “unauthorized special access program” for top-level monitoring of UAP-related activities.

https://c02.purpledshub.com/uploads/sites/41/2024/12/UFOs-above-athens-1.mp4
This footage taken in June 2023 claims to show a line of UFOs in the sky.

The document referred to an extensive database of high-quality evidence collected over several decades, all of which had previously evaded democratic oversight by Congress and most executive branches.

Ann early hearing Held on July 26, 2023, former U.S. Navy pilots testified about events such as encounters with the famous “tic-tock object” and 2004 FLIR (forward-looking infrared) video from the USS. Nimitz Encounters, and GoFast and gimbal videos from the 2015 USS roosevelt Incident.

Previous reports of UAP/UFO sightings date back to the 1940s, and some even centuries earlier. There also seemed to be waves of UFO sightings.

Suspicions of a government cover-up have been floating since the Roswell incident in 1947, but the latest surge in interest in government secrets was sparked in 2017. new york times article About the Department of Defense’s alleged UAP program.

This has led to a bipartisan interest in Congress to uncover the extent to which the U.S. government and intelligence community covered up the sightings. They promised to provide transparency to the American people.

read more:

So far, it’s safe to say that attempts at transparency have been a total failure. Witnesses have refused to disclose classified material that could violate confidentiality oaths, and the government’s refusal to declassify the material (or even acknowledge its existence) has created obstacles. This had an impact on the full-scale discussion on UAP disclosure.

The hearing on November 13, 2024 was no exception. Chairman Nancy Mace began the cover-up game by saying she had no intention of “revealing names.” She also said there were people trying to influence her not to hold this hearing.

All witnesses except Gold are not allowed or unwilling to discuss certain questions in public session, or are not allowed or unwilling to discuss them completely. (Shellenberger claimed it was to protect his journalistic sources). They also reported being subject to threats or outright intimidation not to disclose confidential material.

close encounter

If Mr. Gold had confidential information, he never disclosed it. He simply, and rightly, emphasized the need for independent scientific and academically rigorous investigation of the phenomenon.

However, that did not stop witnesses from claiming knowledge of the crash recovery program and encounters with underwater UAPs and USOs (Unidentified Submersible Objects). They also implied that staff were being treated for injuries sustained from contact with the UAP, and that humanity was already dealing with non-human intelligence (NHI).

Information that, if true, would fundamentally change our view of our place in the universe. This also shows that there is still a lot of sensitive material hidden away.

Witnesses are allowed to speak to some extent about facts that are usually considered “official secrets,” but are prohibited from releasing confidential material that supports their claims. This means you can never really know if what they say is true.

Two senior members of the Eighth U.S. Air Force have identified metal fragments found by a farmer near Roswell, New Mexico as debris from a weather balloon. This is the basis for the 1947 Roswell Incident, which was the alleged crash of an alien spacecraft.

Their testimony is always subject to ample doubt. They may all be sincere in their beliefs or have access to relevant evidence, but it is this personal editing that inevitably leads the witness to failure and, at worst, ridicule. It will be done.

But in many previous hearings, they have only presented what they were told, or in legal parlance, “hearsay evidence”, a type of evidence that legal systems around the world consider to be questionable. I haven’t.

This makes it easy for so-called “falsifiers” to point out that evidence is always announced to be released soon, but is never actually released.

And unfortunately, not all of the witnesses who appeared before Congress on November 13th have impeccable reputations for due diligence and fact-checking information.

For example, Elizondo was recently exposed during a lecture. Presenting a photo said to have been taken in Romania in 2022 Obtained from government contact. He claimed it belonged to a giant “mother ship”, but it turned out to be a fake.

His response was to congratulate those who realized his mistake and to say that he is always happy to see false evidence removed from a serious UAP story.

This “non-human” alien corpse was presented to Mexican politicians in 2023. Experts around the world have labeled the corpse a hoax. – Photo credit: Getty

Regardless, former U.S. officials should reconsider their blind allegiance to secrecy and consider whether there is really any benefit to complying with the government’s demands for silence. Their current reluctance to disclose information only further fuels the US government’s quest to obfuscate the democratic process.

If the witnesses’ claims are true, this knowledge should be shared with the world, not held by one country’s government.

battle of words

The question of whether we are alone in space or even here on Earth is not, by definition, a national security issue. This myopic view, currently held by domestic intelligence agencies, is not appropriate for future policy principles.

It is inevitable that at some point someone will have to make the drastic decision to release or publish confidential material to which they have access, and have to impose their name and risk the consequences.

In fact, the threat of legal consequences not only lends greater credibility to the whistleblower’s character, but also increases the credibility of their testimony. Why risk making confidential documents public unless you are 100% sure they are true?

Even if the truth becomes public, it is unlikely to have any real impact. Steals Jack Ryan’s line, “If a bomb goes off, there’s no use trying to defuse it.” A clear and present danger.

Until then, the meaningless show of unchecked hearsay testimony will continue to be repeated on the floor of Congress. It is better to ignore the protests of witnesses that no real information can be revealed and to actively prevent the spread of unverifiable claims than to remain in a perpetual state of limbo of alien gossip and innuendo. Probably.

Keeping their mouths shut will ultimately do great damage to the truth behind UAP.

Could fossilized excrement unlock the secrets of dinosaur dominance on Earth?

We now know that dinosaurs were giant reptiles that dominated the Earth, but scientists have long wondered why it took them 30 million years to reach their peak. New research on their fossilized poop and vomit may have found the answer suggests that there was food in their waste.

Carnivorous dinosaurs like tyrannosaurus may have their herbivore ancestors to thank for their enormous size. The researchers propose that if these plant-eating animals hadn’t ingested so many plants, dinosaurs might not have evolved into the giant creatures we know today.

The fossilized poop and vomit, known as bromalite or copralite, dates back to around 230 to 200 million years ago, a time long before the reign of the tyrannosaurus and the Chicxulub asteroid impact that led to the extinction of dinosaurs.

Scientists reconstructed a “food web” from the undigested meals of early dinosaurs, revealing the intricate relationships between different species during the Triassic period. By scanning over 500 fossils, they found evidence of various organisms, including beetles, bones, and partially digested fish.

Combining this information with climate data and other fossils provided insights into the diverse flora and fauna coexisting with dinosaurs on Earth.

“Sometimes seemingly ordinary fossils contain remarkable information that cannot be found anywhere else,” said Dr. Martin Kvarnström, a study co-author from Uppsala University in Sweden, as reported by BBC Science Focus.

Dr. Grzegorz Niedzwicki, another co-author from Uppsala University, added, “Understanding the diet of early dinosaurs may help us grasp why this group thrived. The evolution of life on Earth hinges on predator-prey dynamics and feeding habits.”

A study published in Nature analyzed digestive samples from south-central Poland during the Late Triassic period when the region was part of the Pangea supercontinent.

According to experts, increased volcanic activity and humidity favored the growth of moisture-loving plants during this time, potentially influencing the evolution of dinosaurs.

The study utilized advanced scanning techniques to reveal detailed information from the fossils, highlighting changes in vertebrate populations leading up to the dominance of dinosaurs.

The researchers aim to apply this model to study ancient species in other regions and emphasize the importance of fossilized waste in reconstructing ancient food webs.

“Everyone is focused on finding fossilized skeletons, but it’s the waste that offers valuable insights into events from millions of years ago,” remarked Niedzwicki.

Robot Pigeon Uncovers the Secrets of Bird Flight without Vertical Caudal Fins

A pigeon-inspired robot has uncovered the mystery of bird flight without vertical tails found in human-designed aircraft. The prototype has the potential to lead to passenger planes that can reduce drag and fuel consumption.

The vertical stabilizer, or tail fin, in aircraft allows for side-to-side turns and prevents unintentional changes in direction. Some military aircraft, like the Northrop B-2 Spirit, are designed without tails to reduce radar visibility. Instead, they use inefficient methods like flaps creating extra resistance on one side.

Research by David Lentink at the University of Groningen in the Netherlands led to the development of the PigeonBot II to study how birds maintain control without vertical stabilizers.

SEI 230190334

PigeonBot II, a robot designed to imitate bird flight techniques

Eric Chan

The previous model, built in 2020, mimicked bird flight by flapping wings but had a traditional tail. The new design, featuring 52 real pigeon feathers, incorporates a bird-like tail, and successful test flights confirm its functionality.

Lentink explains that PigeonBot II’s success lies in its programmed, reflexive tail movements resembling those of birds. The intricate tail movements contribute to stability, proven by the robotic replica’s flight.

The team controlled PigeonBot II’s nine servo motors, utilizing propellers on each wing for steering and tail adjustments in response to the autopilot’s commands. Lentink notes that the complexity of these reflex movements prevents direct human control of PigeonBot II.

After numerous unsuccessful tests, the control system was refined, enabling safe takeoff, cruising, and landing. Lentink envisions a future where vertical stabilizers are unnecessary, reducing weight and drag in aircraft designs.

Newly discovered species reveals secrets of tardigrade radiation resistance

Newly discovered tardigrade species using genome, transcriptome and proteome analysis Hypsibius henanensis scientists investigated the molecular basis that contributes to radioresistance in these small invertebrates.

Schematic diagram of the mechanism conferring radiation resistance Hypsibius henanensis. Image credit: Li others., doi: 10.1126/science.adl0799.

Tardigrades, also known as tardigrades or moss piglets, are a diverse group of microscopic invertebrates famous for their ability to withstand extreme conditions.

First discovered in 1773, these organisms can live for up to 60 years, grow up to 0.5 mm in size, and are best seen under a microscope.

They can survive in temperatures as low as -272 degrees Celsius (-457 degrees Fahrenheit) or as hot as 150 degrees Celsius (302 degrees Fahrenheit), and temperatures as low as -20 degrees Celsius for several minutes, and for up to 30 years without food or water. Masu. Minus 4 degrees Celsius (minus 4 degrees Fahrenheit) continues for decades.

It can withstand pressures from virtually 0 atmospheres in outer space to 1,200 atmospheres at the bottom of the Mariana Trench.

They also exhibit excellent resistance to ionizing radiation, withstanding doses of gamma rays as high as 3,000 to 5,000 grays (Gy), approximately 1,000 times the lethal dose for humans.

The mechanism of radioresistance in tardigrades remains largely unknown.

Previous studies investigating how they do this have shown that tardigrades have powerful DNA repair abilities.

They also express tardigrade-specific proteins called damage suppressors (Dsup), when expressed in human cells, protects DNA from radiation damage.

In a new study, Lei Li and colleagues at Qingdao University describe a new species of tardigrade. Hypsibius henanensis.

Through detailed morphological and molecular analyses, they also investigated the basis of radioresistance in this species.

The researchers evaluated how exposure to heavy ion beams changes the molecular profiles of animals. They found that 285 stress-related genes were upregulated.

They further uncovered three molecular mechanisms that contribute to radioresistance in organisms.

First, the horizontally transferred bacterial gene DOPA dioxygenase 1 (Doda 1) enhanced radiation resistance by producing betalains (pigments with powerful free radical scavenging properties commonly found in plants, fungi, and bacteria).

Second, proteins unique to tardigrades, TDP1promotes DNA double-strand break repair.

Finally, mitochondrial chaperone genes BCS1Proliferated during the evolution of tardigrades, it is uniquely upregulated in response to radiation and protects cells from radiation-induced mitochondrial damage.

“The extreme environmental tolerance of extremophiles such as tardigrades provides a treasure trove of unexplored molecular mechanisms of stress tolerance,” the authors write.

“Functional studies of these radioresistance mechanisms may further expand our understanding of cell survival under extreme conditions and provide inspiration for promoting human health and fighting disease.”

Uncovering the Secrets of Dinosaurs: An Interview with David Horn on the Impact of New Technology

New Scientist. Website and magazine featuring science news and long-form articles covered by expert journalists on developments in science, technology, health and the environment.

Paul Riding/Joseph Woodhouse

Dinosaurs ruled the earth for around 180 million years. But fossils that are at least 65 million years old are incredibly hard to decipher, so we know very little about what these iconic prehistoric creatures lived. Finding out more has long seemed impossible, but not anymore.

Over the past few decades, new techniques and new specimens have provided previously unimaginable insights into the behavior and ecology of dinosaurs. Combined with insights from modern animals, this has finally enabled paleontologists to understand dinosaur biology, from parental care, migration, and hunting styles to communication, sociality, and combat.

David Horne is one of the researchers trying to find out more about life during the time of the dinosaurs: the paleontologist at Queen Mary, University of London, is soon to publish a book about his latest findings. Revealing dinosaur behavior: What they did and how we know.

Unveiling the Secrets: A Look Behind the Scenes of ’90s Horror ‘Fear the Spotlight’ with Your Ouija Board | Games

I
When the COVID-19 pandemic hit in 2020, it forced Krista Castro and Bryan Shin to rethink their lives. The couple, an animation director and programmer, had been working for major studios but wanted to create their own games. They decided to quit their jobs in 2021 and form A cozy gaming companion. They also became parents around the same time.

They set a goal to create a game in two years. By 2023, they had completed Fear the Spotlight, a ’90s-style horror adventure game. Although it received positive reviews on Steam, they struggled to market it and considered moving on. Then, Blumhouse, the successful horror film production company, approached them.

Blumhouse saw potential in Fear the Spotlight and offered to help. The couple was thrilled to collaborate with them as they shared a passion for horror. Together, they worked on an expanded version of the game set to release soon.

Fear the Spotlight captures the essence of ’90s horror with its atmospheric design and slow pace. Inspired by classic horror games and movies, the game aims to appeal to all horror enthusiasts, even those not typically into gaming.

The couple’s love for horror shines through in the game, incorporating elements from various horror media. With Blumhouse’s support, they look forward to sharing their vision with a wider audience.

Scientists are on the verge of uncovering the secrets behind the construction of Egypt’s ancient pyramids.

A recent study published in July suggests that Egypt’s oldest pyramid, the Step Pyramid of Djoser, may have been constructed using advanced technology. The study proposes that a hydraulic lift system was used during the construction of the pyramid to raise the massive blocks needed for its construction.

The Step Pyramid of Djoser was built as the final resting place of King Djoser, the first or second pharaoh of Egypt’s Third Dynasty during the Old Kingdom, around 4,700 years ago. The pyramid rises in six tiers to a height of 62 meters above the Saqqara plateau, equivalent to the height of a 14-storey building.

If proven true, the existence of this hydraulic lift system would offer an explanation for how the ancient Egyptians were able to construct such monumental structures with the technology available at the time. The study also suggests that a nearby enclosure, known as Gisr el-Mudir, may have served as a “check dam” to capture water and sediment, supporting the hydraulic system.

The study proposes that a sophisticated system of water treatment plants outside the pyramid combined with the Gisr el-Mudir and a ditch controlled water quality and flow. Water would flow into a shaft inside the pyramid where a float system potentially carried building stones to their needed locations. A plug system at the base of the shaft could then drain the water for the process to start again.

Xavier Landreau, president of Paleotechnique and lead author of the study, emphasizes the importance of this discovery in questioning established historical narratives and the technical knowledge possessed by the ancient Egyptian architects. The study also raises the intriguing question of whether the same hydraulic system used to construct the pyramid could have been used to bury the king in his final resting place within the pyramid.

Making Time for Video Games: Insider Secrets

I I don’t often miss my teenage years, but I do miss the time I had to play video games. I used to get into games late into the night, but now that I’m a busy adult, I barely have the time to do that. Outside of covering games for work, I feel like I barely have time to play. So instead of the huge, engrossing role-playing games I once craved, I prefer games I can complete in a few nights. I’m pretty much used to this. The days of 100-hour epics and live service online games are long gone. They’ll come back eventually, when my kids are older.

But more than two years have passed since the release of Elden Ring, a game in my favorite genre by my favorite director, and I suddenly found myself tired of having barely played it. I’d been playing it bit by bit on my PS5, but I’d never been able to get past Rimgrave’s (admittedly vast) starting area. I kept hoping that my partner would take the kids for the weekend, or that I’d have a week off during term time so I could revert to my teenage habits and play hours alone. But… 2 yearsIf I want to play this game, or any big game, I have to make sure I fit it into my real life, which includes work, two small kids, and all the other responsibilities.

Is that even possible? There’s one thing that definitely helps: Steam Deck. Since having kids, I’ve become a lot more reliant on portable consoles. Spending hours uninterrupted in front of the TV without being seen is nearly impossible, and I don’t want to traumatize my kids by blasting them the violent and grotesque scenes of Elden Ring. I’ve been able to play both Zelda games on my Switch because I can take them anywhere and play them occasionally. Plus, these games are huge. So a few weeks ago I bought Elden Ring again, installed it on my Steam Deck, rebooted it, and resolved to defeat the infamous opening boss, Godric the Grafted, and see what’s beyond Stormveil Castle.

At home, I spent all my free time on Steam Deck, to the point of ignoring my family. Kids watching 30 minutes of TV before dinner? Elden Ring. Partner watching Euros? Elden Ring with eyes fixed on the score. Microwaving lunch? Time for Elden Ring. I tried small, achievable adventures like running around looking for unexplored ruins and getting surprised by a dragon in the middle of a lake. I made it through Stormvale Castle and back only to be totally beaten by Godric. I got used to giving up mid-battle, retreating, and looking for something else to do. Progression felt painfully slow, and I hated every time I had to stop playing in the middle of something. At the end of the first week, I checked my playtime. It was 6 hours.

“I left Godric at the castle and warped away to a safer location to just… have some fun.” Photo: Bandai Namco Europe

Six hours?! Is that all the free time I have available in a week? I was seriously depressed. It’s unnatural to play a game like this bit by bit, and when I add up all the stolen time, I’m left with a shockingly small amount of time. At this rate, it’ll take me six months to beat this game, and that’s without playing (or doing) anything else.

My problem was that I was only interested in finishing the game, rather than enjoying it. Six hours is better than zero. I couldn’t play the game the way I used to, so I had to think differently. Instead of reading guides to figure out the best way to progress through the game and trying to progress as quickly and efficiently as possible, I left Godric in the castle, warped to a safer area, and just… tried to have fun. I found a hidden boss and easily defeated it. I opened a treasure chest that teleported me to a terrifying underground mine full of insect-like wizards, then escaped and ended up in a ghostly city. I really liked the Wolverine-esque metal claws I found, but not because they were the best weapon, but because they were fun to use.

After a week of running around like this, I was relieved of the frustration I had felt before. Elden Ring is a terrible game if you try to complete it as quickly as possible in an extremely limited time frame, as most games are. It’s a great game if you focus on the adventure of the moment. I spent about 40 minutes in a smoldering little church trying to kill a red phantom warrior with a giant cleaver that could kill me in two hits, just to see if I could do it. When I managed two parries and killed her after a flurry of desperate sword strikes, I was beside myself. If I had insisted on getting through the game, I would have missed that moment entirely.

I beat Godric last night. With those funny claws that I love so much. I stopped watching the clock for how long I was playing. I stopped worrying about getting the most out of the least amount of effort. And now I’m really having fun. If you’re wondering how to play a huge game when you only have an hour, my advice is to use that hour. It’s the time you have. And an hour of enjoying a game is better than an hour spent wishing you could play longer.

What to Play

If you’re ready to tackle a FromSoftware/Hayao Miyazaki game for the first time and want something more manageable than Elden Ring, I’d recommend the PS5 remake. Demon’s SoulsOriginally released in 2009, this rebuild fixes many of the control and camera flaws, offering a horror-infused dark fantasy vision and great, stress-free combat.

Question Block

Is the consolidation of video game journalism a good thing for gamers? Photo: Josep Martinsson/FIFA/Getty Images

Reader Matt asks:

What would be the consequences if IGN bought the video game news site Gamer Network? If Eurogamer shuts down, we’d riot.

This may seem like an insider question, but it’s an important one for readers of gaming news and reviews — which of you, the Pushing Buttons reader, is a reader of that. In late May, the very large gaming website IGN (I’ll be honest, I worked at IGN from 2010 to 2013) announced that Bought out UK gaming websites include VG247, Eurogamer and GamesIndustry.biz (and, more specifically, I worked for all of these sites from 2006-2010 or so). There are currently just two companies that own pretty much all of the specialist gaming media in the UK: Future Publishing has GamesRadar, PC Gamer and a selection of their magazines, and IGN has everything else.

IGN has previously acquired gaming sites. 1up and GameSpyand they ended up closing down, which doesn’t inspire confidence. But you have to ask: why buy a bunch of beloved brands that are still making a profit from what I’ve heard, and close them down? In 2024, any company in online media needs all the traffic it can get; buying a competitor only to close it down would be a terrible investment in a shrinking advertising economy. That’s why IGN is cautiously hopeful that it will be a good owner of these sites and that it won’t lose a huge chunk of UK games media with this acquisition.

Why is this important? Gaming is one of the few entertainment verticals where specialized media still thrives. Music media is in decline; just look at the fate of NME and Pitchfork. TV and film journalism is mostly newspapers like this one now. But when it comes to games, mainstream media is far behind reporters and critics at IGN,

Unraveling the Secrets of Dark DNA: Scientists on the Verge of Decoding Your Genome

Back in the spring of 2003, the Human Genome Project completed the monumental task of sequencing the human genome.

Even now, The Book of Life remains a captivating and complex subject for the world’s top geneticists, as they work to unravel its mysteries.

This achievement was not only a major milestone for science but for life on our planet, marking the first time any organism had documented its fundamental genetic makeup. This event sparked the ongoing genetic revolution but also presented profound questions.

Questions like, “Why is there so much genetic material?”


undefined


One intriguing aspect of the human genome is that the majority of it seems to serve no apparent function. With around 3 billion nucleotide pairs (A, C, G, T), fewer than 2% (approximately 20,000) of these are genes responsible for coding proteins that direct cellular activity in the body. So, what purpose do the remaining genes serve?

Some have referred to these as junk DNA: seemingly meaningless genetic remnants accumulated over the course of evolution or like a convoluted word puzzle with little coherence.

However, ongoing research indicates that at least some of these regions are not simply genetic debris but have crucial regulatory and corrective roles in the human genome’s protein-coding genes. These DNA sequences are likened to the controls for gene expression.

For instance, enhancer sequences boost gene transcription from DNA to RNA, while silencers have the opposite effect.

The dark genome largely consists of lengthy repeat DNA sequences called Transposons, which play vital roles in gene expression, evolutionary processes, and environmental adaptation.

These “jumping genes” can relocate within the genome, potentially causing significant genetic mutations or inversions. Scientists posit that transposons are linked to evolutionary developments such as opposable thumbs in humans and the loss of tails in humans and apes.

In certain scenarios, transposons may contribute to the onset of tumors and genetic disorders like hemophilia and Duchenne muscular dystrophy, stemming from repetitive DNA sequences associated with transposons.

As a result, the dark genome has become a focal point of medical research, with hopes that increased understanding over the next two decades will lead to revolutionary therapies for genetic diseases.

The Dark Secrets of Mayan Human Sacrifice Unveiled

The ancient Maya civilization of Central America has captivated researchers for centuries with its amazing astronomical calendar and impressive step pyramids.

Along with their rich culture, they are also connected with a darker aspect: human sacrifice. Recent studies reveal that this is indeed a grim reality.

New genetic analysis from the ancient Maya city of Chichen Itza indicates that many of the sacrificial victims were children, with a high number being identical twins.

Published in the journal Nature, the research looked at human remains found in a xultun near the Sacred Cenote.

Radiocarbon dating suggests that the chultun was used between the 7th and 12th centuries AD.

“All individuals in the chultun were children aged three to six,” explained Dr. Rodrigo Barquera, the lead author of the study.

Genetic evidence showed that all 64 individuals tested were male, with about 25% being closely related, including two sets of identical twins.

The occurrence of male identical twins in such a small sample size is unusual.


Barquera noted that twins held significance in Mayan mythology, especially the story of heroic twins defeating the king of the underworld.

This suggests that sacrificing identical male twins was a way to honor the hero twins’ existence.

While this may not have been favorable for identical twins in Maya culture, it was a great honor for their families.

Barquera and his team aim to validate their findings by comparing them with other archaeological sites.

Game Design Secrets of Hidetaka Miyazaki, the Mastermind Behind Elden Ring | Games

TThe famously difficult dark fantasy epic Elden Ring is the second best-selling game in the world in 2022, and with the release of its expansion Shadow of the Erdtree last Friday, everyone is once again debating whether the game is too difficult. Every game developed by From Software since Demon’s Souls in 2009 has sparked this debate, but I’m not going to get into it, because it’s neither interesting nor particularly important. These games are what they are, and you can either choose to get into it or, of course, walk away.

This vision is inherited from the game’s director, Hidetaka Miyazaki, who rose to fame with Dark Souls in 2011 and has also served as FromSoftware’s president since 2014. Though tough, there’s also an element of faith and encouragement in this approach to game design: Elden Ring and other games believe that if you just play patiently and ask other players for help, you’ll eventually win and feel much better.

Miyazaki is an interesting character and one of the most influential artists in the gaming and entertainment world. He was named the “100 Most Influential People in the World” by Time magazine. The 100 most influential people I first interviewed him last year, just before the European launch of Demon’s Souls in 2010. Following his career since then has been one of the highlights for me. I recently interviewed him again in Los Angeles, and it might be comforting for some of us to know that playing his games is sometimes painful, even for him.

“With any game, before launch I’ll spend as much time playing it as I can,” he told me, “but after launch I don’t want to touch it too much because I think I’ll find things that I’ve missed or issues that bother me. And once I’m a player, I don’t have the power to do anything significant to change that, so I stop playing it once it’s out.”

“However, in preparation for Shadow of the Erdtree, I played through the main story of Elden Ring. I’m absolutely terrible at video games, so my approach and playstyle was to use everything I had at my disposal, every assistance, every help the game offered, and all of my knowledge as a game designer…The freedom and open-world nature of Elden Ring probably lowered the barrier to entry, and I may have benefited from that more than anyone else as a player.”

Watching Miyazaki pick up the controller and agonize over the world he’s created (and its imperfections that only he would notice) made me laugh heartily. It’s a true commitment to his game design philosophy of improving through failure, a mantra that seems to permeate his entire life. Miyazaki is a very hands-on director, and all of his games clearly bear his influence, but during his decade as president of From Software, he has tried to pass on his knowledge and artistic approach to others, giving them the space to fail as well.

“The budget, the size, the scope, everything has expanded to a level where I think there is not as much room for failure as there was before,” he told me. “From Software has its own way of hedging, so to speak. For most of our projects, we have partners who fund the projects. … From a business management perspective, we are not betting everything on one project. At the same time, we need to find the right projects where we can afford to fail. Even if they are small in scope or size, or a small module within a bigger one, we need to have room to fail. I think that’s where a lot of young game directors can try and learn from. Understanding and identifying where we can afford to fail is how we develop talent.”

Miyazaki considers Elden Ring a “turning point” for FromSoftware: “There will be a clear difference between before and after Elden Ring… [2023’s mech game] “Armored Core VI,” he says. He expects to see more games from the company’s other directors soon, rather than just himself. “I think Elden Ring is the limit for FromSoftware right now, in terms of scale. We’ve used all the resources and talent available to us. … There are concerns about scaling up even further. Perhaps having multiple projects is the next step, and other younger talents will have the opportunity to manage and oversee the game design of smaller projects.”

Shadow of the Elder Tree is the end of Elden Ring for now. With the exception of Dark Souls, Miyazaki generally doesn’t make sequels. Demon’s Souls, Sekiro, Bloodborne, and Elden Ring are all standalone works, and I get the impression he likes it that way. Interestingly, though, he wouldn’t mind someone else continuing The Land Between in a different medium.

“I don’t see any reason to rule out another interpretation or film of Elden Ring,” he told me, “but I don’t think myself or FromSoftware have the knowledge or the ability to create something in another medium. That’s where a very strong partner would come in. We’d need to build a lot of trust and agreement on whatever we’re trying to achieve, but I’m certainly interested.”

If any Soul Geek readers work in arthouse film production, consider this an opportunity to jump on.

Paleontologists Uncover Secrets of ‘Elgin Marvel’ Fossil

The “Elgin Marvel” fossil is a block of reddish sandstone containing a natural cast of a Permian skull and jaw. Dicynodonts It was discovered in the Hopeman Sandstone Formation near Elgin, Scotland. According to a new study, the specimen Gordonia traquairi A type of dicynodont that lived between 254 and 252 million years ago, when the Earth was made up of a single land mass called Pangaea.

Artist image Gordonia traquairi Image courtesy of Scott Reed.

Gordonia traquairi It belongs to a group of extinct species known as dicynodonts, and is characterized by its stocky body, beak, and tusks.

This organism lived relatively shortly before the end-Permian extinction (the Great Dying), the worst mass extinction event in history, which occurred about 252 million years ago and wiped out much of life on Earth.

The Elgin Marvel specimen is one of the best-preserved in a series of fossils collected near Elgin in northeast Scotland.

These are collectively known as the Elgin reptiles. Gordonia traquairi are closely related to mammals.

In the new study, paleontologist Heidi George of the University of Edinburgh and her colleagues performed micro-CT scans of the cavities the animal carved into the sandstone before the bones deteriorated.

The scan produces a three-dimensional representation of the skull anatomy, including details of the brain.

These insights help us understand animal behavior and the biology behind it, providing clues about the evolution of this and other species.

Gordonia traquairi The fossil shares many physical characteristics with similar remains found in China, indicating that dicynodonts were diversifying around the world just before the devastating extinction.

The Elgin reptile is the only known example of this type of fossil from Western Europe.

Palaeontologists hope that the increasing use of micro-CT scanning as a tool to study fossils in detail, combined with the trend toward open sharing of data, will provide opportunities to add to the body of knowledge in the field.

“The Elgin Marvel is a fascinating fossil of an ancient mammal relative that is one of the best-preserved of the world-famous Elgin reptiles,” Dr. George said.

“Most of these famous fossils were discovered more than a century ago, but it’s only recently that new techniques have revealed more detail and provided valuable insights into their skull and brain anatomy and lineage.”

“It’s hard to imagine, but about 250 million years ago Scotland was a desert covered with sand dunes. Gordonia “God was in control of the world,” says Professor Steve Brusatte of the University of Edinburgh.

“By studying them, we can learn about some of the earliest stages of our own evolution.”

Cracking the Code: Scientists on the Brink of Revealing the Secrets of Dark DNA

In the spring of 2003, the Human Genome Project completed the task of sequencing the human genome, marking a significant moment for science and life on Earth. The genetic revolution that followed raised questions about the meaning of the genome, particularly the fact that most of it seems to be non-coding. Less than 2% of the genome consists of genes that code for proteins, while the rest was once considered junk DNA.

However, recent research has shown that this “dark genome” plays a crucial role in regulating gene expression and has evolutionary significance. Long repeat sequences like transposons can impact genetic mutations and adaptation, leading to the development of features like opposable thumbs and the loss of tails in humans and apes. Understanding these once-neglected parts of the genome is now a focus of medical research for potential therapies for genetic diseases.

The Power of Music to Discover the Universe’s Hidden Secrets

Music and physics are two disciplines that transcend mere study to become intertwined aspects of human creativity. This hidden harmony between music and physics has been acknowledged by luminaries such as Albert Einstein, who expressed a longing for music had he not pursued physics.

As someone who navigates both fields, I have uncovered deeper connections between them. My journey began in the Bronx, where the worlds of hip hop and science collided in unexpected ways. Later, while studying at Imperial College London, I witnessed the fusion of artistic expression and scientific inquiry in Brian Eno’s studio.

This intersection between art and science inspired me to explore further and led me to write the book “Physics Jazz.” Through this exploration, I delved into the commonalities between music and physics, from improvisation to quantum uncertainty.

My passion for sharing these discoveries prompted the creation of the course “Jazz in Modern Physics” at Brown University, bridging the gap between disciplines and offering students a new way to appreciate the symphony of the universe through mathematics and melody.

Believing in the transformative power of education, I founded the “Sound + Science” after-school program to provide underserved students with an opportunity to explore the fusion of music and physics through hands-on experimentation and collaboration.

This fusion of art and science celebrates human ingenuity and the interconnectedness of the universe. In embracing this harmonious blend, we can unlock the mysteries of the universe and delve into the depths of the human soul.

Researchers uncover the secrets behind Pluto’s peculiar pear shape

Pluto's surface is dominated by Sputnik Planitia, a giant pear-shaped basin. Although it appears to be of impact origin, modeling has not yet accounted for its unique shape. Planetary scientists at the University of Bern have proposed an impact mechanism that would both recreate the topography of the basin and explain the alignment around the Pluto-Charon axis. According to their research, Sputnik Planum was created by a collision between Pluto and a planet about 700 km (435 miles) in diameter.



This mosaic of Pluto was created from the New Horizons LORRI image taken on July 14, 2015 from a distance of 49,700 miles (80,000 km). This view is projected from 1,118 miles (1,800 km) above Pluto's equator, from northeast over the dark, cratered Cthulhu region to a bright, smooth, icy plain called Sputnik Planum. I am. Pluto's north pole is off the left side of the image. This mosaic was created using panchromatic imagery from the New Horizons LORRI camera, with color overlaid from New Horizons' built-in Ralph color mapper. Image credit: SA Stern other.

In 2015, NASA's New Horizons spacecraft revealed that Pluto's surface is geologically complex.

The region is dominated by a 1,200 x 2,000 km (746 x 1,243 mi) nitrogen ice-filled basin called Sputnik Planitia.

Sputnik Planitia is located in the western part of Pluto's Tombow region, a famous heart-shaped structure.

This basin is 3 to 4 km (1.9 to 2.5 miles) lower in elevation than most of the dwarf planet's surface.

“Sputnik Planitia's bright appearance is due to the fact that it is filled with mainly white nitrogen ice, which moves and convects to constantly smooth the surface,” said Dr. Harry Ballantyne, a planetary scientist at the University of Bern. Ta.

“Due to the low altitude, this nitrogen likely accumulated quickly after the impact.”

“The eastern part of the 'heart' is also covered with a similar but much thinner layer of nitrogen ice, the origin of which is not yet clear to scientists, but is probably related to Sputnik Planum.”

“The elongated shape of Sputnik Planitia strongly suggests that the impact was an oblique impact rather than a direct head-on impact,” said Dr. Martin Jutzi, a planetary scientist at the University of Bern.



This high-resolution image of Pluto was taken by New Horizons on July 14. Pluto's surface boasts an astonishing range of subtle colors, highlighted in this view by a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have unique colors that tell complex geological and climatological stories that scientists are only beginning to decipher. Image credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute.

The authors used smoothed particle hydrodynamics (SPH) simulation software to digitally recreate such collisions while varying both the composition of Pluto and its impactors, as well as the speed and angle of the impactors. did.

These simulations confirmed our suspicions about the oblique angle of the impact and determined the configuration of the impactor.

“Pluto's core is so cold that the rocks remain very hard and do not melt despite the heat of the impact, and the angle and low speed of the impact prevents the impactor's core from sinking into Pluto's core, leaving it intact. “It's like a splatter,” Dr. Ballantyne said.

Dr. Eric Asfaug, a planetary scientist at the University of Arizona, added: “Somewhere beneath Sputnik are the remains of the core of another giant object that Pluto was not able to fully digest.”

“The strength and relatively low velocity of this core were the keys to the success of these simulations. At low strengths, the highly symmetrical remnants look nothing like the teardrop shape observed on New Horizons. surface features are obtained.

“We're used to thinking of planetary collisions as incredibly violent events, and we can ignore the details except for things like energy, momentum, and density.”

“But in distant solar systems the velocities are very slow and the solid ice is strong, so the calculations need to be more accurate. That's where the fun begins.”

The research team's findings also shed new light on Pluto's internal structure.

“In fact, a giant impact like the one simulated is much more likely to have occurred very early in Pluto's history,” the researchers said.

“But this poses a problem: giant depressions like Sputnik Planitia are expected by the laws of physics to move slowly towards the dwarf planet's poles over time because of the lack of mass. ” But paradoxically, it is close to the equator. ”

“A previous theoretical explanation was that Pluto, like several other planetary bodies in the outer solar system, has an ocean of liquid water underground.”

“Previous explanations suggest that Pluto's icy crust thins in the Sputnik Planum region, where the oceans swell and liquid water is denser than ice, creating a mass surplus that triggers a shift toward the equator. It will be.”

“But new research offers a different perspective.”

“In our simulations, all of Pluto's primordial mantle is excavated by the collisions, and as the impactor's nuclear material splatters into Pluto's core, it creates a localized overmass that causes the absence of a subsurface ocean. Or, at best, it could be explained as moving toward the equator without the ocean being present, “very thin,'' Dr. Yutzi said.

“This novel and original origin of Pluto's heart-shaped feature may lead to a deeper understanding of Pluto's origins,” said Dr. Adeen Denton, a planetary scientist at the University of Arizona.

Solar Eclipses: Unveiling the Secrets of the Universe for Centuries

A total solar eclipse is a great opportunity to learn about the sun

ESA/Royal Observatory of Belgium

A total solar eclipse occurs somewhere on Earth approximately every 18 months, and that has been the case throughout human history. Not surprisingly, people have been studying these dramatic events for just as long, with the first records of solar eclipses dating back more than 3,000 years. During that time, we learned an amazing amount about the Sun, Earth, and even the basic laws of physics from total solar eclipses.

For most of history, humans could only see the faint outermost layers of the sun during total days (periods when the moon covers the entire sun’s disc). This faint blanket of plasma, called the corona, has been central to the scientific advances resulting from the study of solar eclipses.

Solar eclipse in 2024

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.

The corona is home to many of the sun’s most fascinating phenomena, including coronal mass ejections (CMEs), which occur when the sun’s swirling magnetic fields blast bundles or clumps of matter into space. If a CME were to hit Earth, it could damage satellites and power grids, and could be extremely dangerous to astronauts in space, beyond the protection of Earth’s atmosphere.

“The Sun’s magnetic activity changes over time and changes across the star’s surface.” meredith mcgregor at Johns Hopkins University in Maryland. Currently, there is no good way to predict this activity. But by studying the coronavirus, we may be able to start doing just that.

A total solar eclipse isn’t the only way to see the outermost layer of the sun. There is also a device called a coronagraph, which uses a shade to block the sun’s disk in a type of artificial solar eclipse. These instruments are used not only to study our own star, but also to study other stars that are more distant and look for planets around them that would otherwise be hidden in the glare of starlight. It is also important. “The idea of using coronagraphs to block out the light of other stars and look for extrasolar planets comes from natural solar eclipses,” MacGregor says.

The same dimness that makes the corona difficult to observe in totality also makes it an excellent target for spectroscopy. Spectroscopy works by splitting light into its constituent wavelengths. This allows researchers to determine which elements are present in a material by the unique pattern of wavelengths each element emits or absorbs. Helium was discovered using spectroscopy during a solar eclipse in 1868. This was the first time an element had been discovered by studying the sky.

Shortly thereafter, astronomers discovered what appeared to be another new element in the corona, which they named corona, but it turned out that it was simply iron heated to extraordinary temperatures of several million degrees. found. Even though it was not a new element, it was a puzzling discovery. The surface of the sun is only about 5,600 degrees Celsius, so why is the outermost layer so hot?

I said, “Imagine you’re at a campfire and you start walking away from the campfire. It’s supposed to be cold, but it’s much hotter.” Frederick Bartley at the Ohio State Science and Industry Center. “That’s what’s happening with coronavirus, but no one knows why.”

The eclipse also provided some of the first proofs of Albert Einstein’s theory of general relativity, which governs the behavior of large-scale gravity. One of the key predictions of general relativity is that massive objects should bend the trajectory of light as they pass by. Einstein first published the theory in his 1915, and evidence of its truth came in his 1919 when astronomer Arthur Eddington observed starlight bending around the sun during a solar eclipse.

As a total solar eclipse passes over Central and North America this month, astronomers will continue a long-standing tradition of using the totality to observe the sun and precisely how it affects the space around it. It turns out. The sun still has many secrets to unravel, and eclipses are one of the best times to study them.

Hidden Secrets of Atomic Structure Uncovered by Scientists

Groundbreaking research led by Professor Motoki Shiga has unraveled the complex atomic structure of glass, revealing its unique patterns and anisotropy. This research paves the way for advanced exploration of glass materials using AI and machine learning techniques.Credit: Motoki Shiga

Glass is an essential material in our daily life and serves a variety of purposes, such as insulating our homes and forming the screens of our computers and smartphones. However, its widespread historical use stands in contrast to the scientific mystery posed by its disordered atomic structure. This puzzling arrangement of atoms complicates efforts to fully understand and manipulate the structural properties of glasses. Therefore, designing effective functional materials from glass remains a difficult challenge for scientists.

Advances in glass research

To further elucidate the structural regularities hidden in glassy materials, the research group focused on the ring shape of the chemically bonded glass network. A research group including Professor Motoki Shiga of Tohoku University’s unprecedented scale data analysis center has developed a new method to quantify the three-dimensional structure of the ring and the symmetry of the structure, “roundness” and “roughness.”

Breakthroughs and future directions

“Structural units and structural order beyond chemical bonds have long been inferred through experimental observations, but until now scientists have avoided identifying them,” Professor Shiga says. “Furthermore, our successful analysis contributes to the understanding of phase transitions such as vitrification and crystallization in materials and provides the necessary mathematical explanations to control the structure and material properties of materials.”

Looking to the future, Shiga and his colleagues plan to use these techniques to devise procedures for exploring glass materials, procedures based on data-driven approaches such as: machine learning And AI.
