Dead Planets Society is a podcast that takes some crazy ideas for how to tinker with the universe and tests their effects against the laws of physics, from snapping the moon in half to causing doomsday events with gravitational waves. apple, Spotify or our Podcast Page.
One moon isn’t enough. While Earth only has one moon, other planets have many. Jupiter has 95 moons, putting its shining cosmic partner to shame with only one. In this episode of Dead Planets Society, we try to light up the night sky with as many moons as possible.
But it’s not as simple as just throwing a bunch of rocks into orbit. So in this episode, hosts Leah Crain and Chelsea White Shawn Raymond We asked a researcher from the University of Bordeaux in France for help with the details, who suggests we could build a ring of 10 moons, each of which would orbit Earth in different phases, causing strange little eclipses as they orbited the planet.
And it’s not just the moon. In 2018, Raymond and Juna Kollmeyer Researchers at the Carnegie Observatories in California have found that it’s theoretically possible for Earth’s moon to have its own orbital satellite, known as a lunar lunar. Such a satellite might not be stable due to the presence of a gravitational anomaly on the moon, so our host has been adding a giant hand blender to his space tool belt to try and smooth things over. If things get sorted, we could have a lunar lunar, or even a lunar lunar, lighting up the night sky.
The moon is bright because it reflects sunlight, and these new moons could be the perfect place to line up giant solar panels, unobstructed by the atmosphere and clouds that plague Earth’s surface. And because the moon is so bright, it would probably be impossible to see the stars from Earth’s surface, but in relatively small detail.
An even bigger problem is that the more complex and crowded the orbit, the greater the risk of these moons colliding with each other, which could give Earth beautiful rings like Saturn, but could also destroy life on Earth.
Dead Planets Society is a fun and subversive podcast about space. New ScientistIn each episode, hosts Leah Crain and Chelsea White explore what would happen if we were given cosmic powers to rearrange the universe. They speak to astronomers, cosmologists and geologists to find out what would happen if we ripped a hole in a planet, unified the asteroid belt or destroyed the sun.

How spaceflight affects astronauts' health may be better understood thanks to the creation of the first “space-omics” biobank, a collection of thousands of blood and tissue samples and medical information taken on multiple space missions.
These include missions to the International Space Station as well as SpaceX's Inspiration 4, the first private spaceflight to send four non-government-trained astronauts into space for three days in 2021.
The resource, called the Space Omics and Medical Atlas (SOMA), contains detailed medical data, collectively known as biomarkers, such as DNA damage and changes in people's gene activity and immune system function.
Space flight is known to pose certain health risks. For example, astronauts experience reduced bone density and muscle mass due to weightlessness, and high levels of radiation in space can damage cells and DNA, causing a variety of health effects on the body. Astronauts are more likely to develop heart disease Later years and Some people have experienced a decrease in vision After going into space.
By consistently collecting astronauts' medical data through the SOMA biobank, researchers may be able to better understand these changes and develop ways to mitigate them, the researchers say. Christopher Mason He is a professor at Weill Cornell Medicine in New York and helped establish the biobank.
“Biomarkers don't necessarily translate into anything clinically meaningful, but they're a good way to understand how this unique environment is affecting us.” Damien Bailey The researchers are from the University of South Wales in the UK, but were not involved in the study.
One of the findings from the Inspiration 4 mission was that although astronauts experienced changes in numerous biomarkers, most measurements returned to normal within a few months of returning to Earth.
This suggests that sending private citizens into space poses no greater health risks than sending professional astronauts, Mason said. “Instead of training them for decades, we can start opening up space to more people.”
Results from Inspiration 4, which had two men and two women on board, also suggested that changes in gene activity returned to normal more quickly in women. This may be because women's bodies have to be able to cope with the possibility of pregnancy, Mason says. “Being able to withstand big changes in physiology and fluid dynamics could be great for managing pregnancy, but it could also help manage the stresses of spaceflight.”
Timothy Etheridge A researcher from the University of Exeter in the UK says it would be beneficial to have a common resource that researchers around the world can use. “We need a consistent approach to collecting samples,” he says.
Thomas Smith The researcher, from King's College London, says understanding the health effects of spaceflight will become even more important if longer-term missions take place, such as trips to Mars. “Anything that leads to longer-term missions makes it even more important to know what's going on and, ideally, to be able to address it,” he says.
The Humboldt penguin populations along Chile’s central coast have seen a significant decline, making them one of the most at-risk species out of the world’s 18 penguin species and facing the threat of extinction, according to experts.
A recent survey conducted by scientists on two islands off the central Chilean coast revealed a drastic decrease in breeding pairs or active nests, from 842 last year to just one this year.
Veterinarian Paulina Arce, who specializes in penguins, noted that populations have either decreased or remained stable on all the islands that were studied.
“This could lead to something even more serious – the extinction of the species,” Arce cautioned.
The Humboldt penguin (Spheniscus humboldti) is found on the Pacific coast of Chile and Peru and is named after the Humboldt Current that it inhabits. These flightless birds can weigh up to 5 kg (11 lbs) and grow up to 70 cm (2 ft 3 in) in length as adults.
Diego Penaloza, president of the Safari Conservation Foundation, identified marine pollution, lack of pet supervision, and disturbance of nesting sites as the main threats to penguins in the wild.
Moreover, avian influenza exacerbated by the El Niño weather pattern has led to devastating consequences for penguins and other wildlife, causing breeding rates for Humboldt penguins to plummet almost to zero, as outlined by Javier Mesa, biodiversity conservation manager for CONAF, the national forestry agency.
“Because of the avian flu and the El Niño weather phenomenon, all the food was swept southwards, resulting in a near-zero breeding rate for penguins in northern Chile and the deaths of many more penguins,” Mesa explained. “It was a perfect storm.”
Rare Earths Norway, a mining company, has made a groundbreaking announcement of discovering Europe’s largest proven deposit. This discovery of rare earth elements is highly regarded and could potentially be a game-changer for the Nordic countries and the broader region.
This continental Europe’s largest rare earth deposit, not controlled by China, presents a significant opportunity for Europe amid its oil crisis. The demand for rare earths and critical minerals is expected to grow exponentially as the transition to clean energy accelerates.
Rare Earths Norway revealed in a statement on June 6 that the Fen carbonatite deposit in southeastern India has an estimated 8.8 million tonnes of total rare earth oxides (TREO) with economically mineable prospects. The company also estimates 1.5 million tonnes of magnet-related rare earth elements that can be used in electric vehicles and wind turbines.
This discovery surpasses a significant rare earth deposit discovered last year in Sweden. Rare Earths Norway CEO Alf Rystad emphasized the importance of this discovery, stating that there is currently no mining of rare earth elements in Europe.
Going forward, Rare Earths Norway aims to contribute to mining at least 10% of the EU’s annual demand for rare earth elements by 2030. The company also plans to develop the Telemark rare earth deposit southwest of Oslo to strengthen Norway’s position in the European rare earths value chain.
The International Energy Agency highlighted the shortage of current supplies needed to transform the energy sector due to the geographic concentration of many energy transition elements. China, the world’s largest rare earth ore processor, plays a significant role in supplying rare earth elements worldwide.
Rare Earths Norway intends to continue exploration work at the site with further drilling planned for the coming month. The company aims to begin production by 2030 to contribute to Europe’s rare earth supply and reduce dependence on Chinese sources.
In a recent interview, Alf Rystad remarked that while the discovered resources are valuable, they won’t increase in value compared to oil and gas. He mentioned European Commission President Ursula von der Leyen’s belief that lithium and rare earth elements will become more important than traditional fossil fuels in the future.
AI, whether it stands for artificial intelligence or Apple intelligence, is a hot topic today. It’s time to have a conversation about it. [sits backwards on chair] password.
One significant change coming to Apple’s platform next year is the creation of a new Password app. This was somewhat overshadowed by the reporting from last night’s Apple event in Cupertino and New York by Kari Paul and Nick Robbins-Early.
9to5Mac reports that the new passwords app on iPhone home screens this fall will enhance the security of computing for average users who may not be familiar with password management apps.
The new Passwords app consolidates and simplifies existing password features on iOS and macOS, making them more accessible to users. It will display a list of all user logins after verifying identity.
Apple has expanded its password management capabilities over the years, offering security audits, alerting users to compromised passwords, sharing options, and data import/export features.
The focus on identity, rather than just passwords, highlights Apple’s aim with the new Passwords app. Managing digital identity remains a challenge, with passwords serving as the primary method of online identity verification but coming with inherent security risks.
Password managers like 1Password have emerged as a solution, but the industry is exploring alternatives like passkeys to address the limitations of traditional password systems.
While passkeys promise a password-free future, their adoption has been slow due to limited support from websites and initial user challenges. Despite the potential benefits, concerns remain about the security and user experience of passkeys.
From password managers to passkeys, the quest for secure and user-friendly authentication methods continues.
The evolution of identity verification extends beyond passwords to technologies like AI avatars. While the concept of AI systems participating in meetings remotely is not yet fully realized, advancements in voice synthesis and AI present new challenges and opportunities for digital identity verification.
As technology progresses, ensuring secure and seamless identity verification methods remains a crucial aspect of digital life.

There is a growing trend in the beauty industry to seek treatments for bloating and cellulite, with lymphatic drainage massage becoming increasingly popular among A-list celebrities like Jennifer Aniston, Kim Kardashian, and Sean “Diddy” Combs.
These celebrities have touted the fast health benefits and weight loss advantages of this treatment, but what exactly does lymphatic drainage massage do?
Lymphatic drainage massage is unique as it targets the lymphatic system, setting it apart from other massage therapies such as Swedish, sports, deep tissue, and aromatherapy. Each type of massage offers different benefits, so your choice depends on your desired results.
The lymphatic system is a crucial part of the body’s immune system, consisting of tissues, organs like the spleen and bone marrow, and a network of interconnected blood vessels and lymph nodes. These components work together to filter out waste and maintain fluid balance, producing white blood cells to fight infections.
People opt for lymphatic drainage massage to combat cellulite as the treatment aids the absorption of fat and excess fluids back into the bloodstream.
Lymphatic drainage massage can benefit those dealing with lymphedema, fibromyalgia, sports injuries, deep vein thrombosis, and lymphatic buildup post-cancer treatment. While athletes benefit from preventative and restorative sports massages, lymphatic drainage massage can aid recovery after injury or surgery.
If your lymphatic system is not functioning optimally, you may experience swelling and puffiness in various parts of the body. Lymphatic drainage massage can help alleviate these symptoms by improving circulation, reducing swelling, and eliminating toxins.
While lymphatic drainage massage may improve the appearance of cellulite, it cannot completely remove it. The treatment may lead to temporary weight loss due to the elimination of excess fluids.
During a lymphatic drainage massage, the therapist employs gentle pressure techniques that do not cause discomfort or skin redness. The massage focuses on clearing and absorbing, enhancing skin health.
Have you ever experienced a gig so bad that you can now laugh about it?
I have a memory of performing at village festivals, outdoors, for families. None of the comedians were aware that their jokes had to be kid-friendly. In the beginning, I only had five minutes for jokes and no alternative, gentler material. The audience was roped off for a dog show later on, so people had to watch from a distance of about 10 meters. There were only five people behind the ropes, one of them in a Peppa Pig costume who heckled the entire show. After just five minutes of performing, the crowd fell silent, and when another performer used inappropriate language, the show was cut short.
Can you tell us about your upcoming show, “(Role) Model”?
The show is about 55 minutes long, possibly longer with a larger audience. I want it to feel like a fun conversation with a toxic best friend. It also explores the idea of becoming an overnight sensation or gaining fame for dancing with your parents. I delve into the contrast between who I want to be and who others expect me to be, questioning why neither seems achievable.
Do you have any pre-show rituals?
I find myself repeating “I don’t want to do this” and “Why am I doing this?”

Definitely. Despite initial skepticism towards my online work, having a large following has helped change perceptions. People are recognizing the importance of an online presence in today’s entertainment landscape.
What lessons have you learned from stand-up comedy?
Embracing imperfections can resonate with audiences.
What excites you the most right now?
I’m thrilled to be fully engaged in something I love — comedy. Plus, I’m appearing in a cat litter commercial next week, which means spending time with an adorable professional cat named Tom.
Astronomers using the NASA/ESA Hubble Space Telescope NGC 2005A globular cluster located in the constellation Dorado, 162,000 light years from Earth.
This Hubble image shows the globular cluster NGC 2005. The color composite was created from images taken in visible and near-infrared light by Hubble's Wide Field Camera 3 (WFC3). It is based on data acquired through three filters. The colors are produced by assigning a different hue to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / F. Niederhofer / L. Girardi.
Globular clusters are dense systems of very old stars bound by gravity into a single structure about 100-200 light years in diameter.
Star clusters contain hundreds of thousands, or even millions, of stars. A large mass at the center of the cluster pulls the stars inward, forming a sphere of stars. sphericalThese clusters are named after the Latin word ” ,” which means “little sphere.”
Globular clusters are among the oldest known objects in the universe, relics of early galaxy formation.
Of the Milky Way's 150 globular clusters, about 70 are located within 13,000 light-years of the galactic center, where their density tends to peak.
“Studying globular clusters in space is a bit like studying fossils on Earth: just as fossils give us insight into the characteristics of ancient plants and animals, globular clusters reveal the signature of ancient stars,” the Hubble astronomers said.
“Current theories of galactic evolution predict that galaxies will merge with each other.”
“The relatively large galaxies observed in the modern universe are widely thought to have formed by the merger of smaller galaxies.”
“If this is correct, astronomers will see evidence that the oldest stars in nearby galaxies originated in different galactic environments.”
“Globular clusters are known to contain ancient stars, and their stability makes them excellent laboratories to test this hypothesis.”
“NGC 2005 is just such a globular cluster, and its very existence provides evidence in support of the theory of galactic evolution by mergers.”
NGC 2005 is located about 750 light-years from the center of the Large Magellanic Cloud, the Milky Way's largest satellite galaxy.
Also known as ESO 56-138, this globular cluster is discovered It was discovered on September 24, 1826 by Scottish astronomer James Dunlop.
“The stars in NGC 2005 have a different chemical composition than the stars in the surrounding Large Magellanic Cloud,” the researchers said.
“This suggests that the Large Magellanic Cloud merged with another galaxy at some point in its history.”
“While other galaxies have long ago merged or dispersed, NGC 2005 remains as an ancient witness to a long-ago merger.”
The Solo 4 headphones are an improvement on the fan-favorite headphones that made Beats famous, upgraded with longer battery life, improved sound quality, and the latest features favored by Apple and Android.
The original Solo HD was launched in 2009 and was updated in 2016 as the Solo 3 after Apple acquired Beats. Now in its fourth generation, the Solo headphones are the company’s smallest and lightest at £200 (€230 / $200 / AU$330), making them cheaper than the £350 Studio Pro.
The design remains essentially the same but has been updated with premium materials and color options. While competitors have moved away from this shape, Beats continues to offer on-ear headphones that sit on top of the ears rather than around them.
A slight reduction in pressure on the sides of your head and softer ear cushions make these headphones more comfortable than previous models. They fold up for easy transport and come with a compact, easy-to-use case.

Italian archaeologists have unearthed the so-called Sacramento in Pompeii, the ancient Roman city frozen in time after the devastating eruption of Mount Vesuvius in 79 AD.
A 2,000-year-old sacramental vessel discovered in Pompeii, Italy. Image courtesy of Pompeii Archaeological Park.
The newly discovered sacrarium – an ancient temple used for ritual activities and storing sacred objects – covers an area of approximately 8 square meters.
The chamber was excavated in the center of Pompeii by Dr. Gabriel Suftriegel and his colleagues from the Pompeii Archaeological Park.
“Against the blue background of the wall, two female figures are depicted on either side of a central niche,” the archaeologists said in a statement.
“The figures in the side niches represent the horae, the four seasons, while the figures in the central panel represent an allegory of agriculture and shepherding, shown with the symbols of the plough and pedum (a short staff used by shepherds and hunters).”
“The blue color seen in this room is rarely seen in Pompeii frescoes and was usually used in more elaborately decorated rooms.”
In the sacristy, researchers found 15 transport amphorae and a set of bronze objects, including two jugs and two lamps.
They also unearthed large amounts of ancient building materials that can be used in the renovation work.
“A pile of empty oyster shells was found by the front door. The shells had probably been crushed into small pieces and added to the plaster or mortar,” the scientists said.
“The room was found in a building located on the southern side of a block (insula) belonging to the secondary area of the larger domus,” the researchers added.
“The structures discovered include a bathhouse, which is still being excavated, and a large reception room decorated with black frescoes overlooking a courtyard with a staircase leading to the first floor of the complex.”
“These excavations are part of a wider project aimed at strengthening the boundaries between excavated and unexcavated areas and improving the hydrogeological structure in order to more effectively and sustainably protect Pompeii’s vast archaeological site (more than 13,000 rooms in 1,070 residential units, public areas and sacred sites).”

Planetary scientists first became aware of the connection between Earth and Jupiter in 2018, when they noticed striking similarities in images of Jupiter's giant cyclones and turbulent ocean currents. In 2022, they Analyzed High-resolution infrared image of a cyclone on Jupiter taken by NASA's Juno spacecraft. Analysis reveals that a type of convection similar to that seen on Earth helps sustain Jupiter's storms, which can be thousands of miles wide and last for years. The 2022 study focused directly on Jupiter's cyclones, but the authors also saw thin tendrils called filaments in the spaces between the vortices of gas. These filaments have analogues on Earth, and the authors used Juno's detailed images to study whether this similarity to Earth's oceanic and atmospheric processes is merely superficial.
This composite image, created from data collected by the JIRAM instrument on NASA's Juno spacecraft, shows a central cyclone at Jupiter's north pole and eight surrounding cyclones. JIRAM collects data in infrared, and the colors in this composite represent radiated heat. The yellow (thinnest) clouds have a brightness temperature of about -9 degrees Fahrenheit (-13 degrees Celsius), while the dark red (thickest) clouds have a brightness temperature of about -181 degrees Fahrenheit (83 degrees Celsius).

Fronts are often featured in weather forecasts (for example, cold fronts and storm fronts) and apply to both gases and liquids.
A front is a boundary between masses of gas or liquid that have different densities due to differences in properties such as temperature.
In the ocean, fronts can also form due to differences in salinity, which, along with temperature, affects the density of seawater.
The main characteristic of a front is that its leading edge is characterized by strong vertical speed and can generate wind and currents.
To understand the role of the filaments clearly visible during Jupiter's cyclones in the Juno images, Dr. Leah Siegelman of the Scripps Institution of Oceanography and Dr. Patrice Klein of the California Institute of Technology examined a series of infrared images from Juno.
The series of images was taken 30 seconds apart of Jupiter's north polar region.
Because the images were taken in infrared, the team was able to calculate the temperature, finding that brighter areas were warmer and darker areas were cooler.
On Jupiter, the hotter parts of the atmosphere correspond to thin clouds, while the cooler parts are covered by thicker clouds that block more of the heat emanating from Jupiter's superheated core.
The researchers then tracked the movement of the clouds and filaments over the 30-second intervals between photos to calculate horizontal wind speeds.
These two pieces of information allowed the scientists to apply methods from ocean and atmospheric science to Jupiter to calculate vertical wind speeds that correspond to the temperatures and horizontal wind speeds the researchers derived from the images.
Calculating vertical wind speeds, they found that Jupiter's filaments do in fact move like Earth's fronts.
The vertical wind speeds at the edges of Jupiter's fronts also mean that the fronts transport energy in the form of heat from the planet's hot interior to the upper atmosphere, potentially generating large cyclones.
Although convection is the primary driving force, fronts account for a quarter of the total kinetic energy powering Jupiter's cyclones and 40 percent of the vertical heat transport.
“These cyclones at Jupiter's poles have continued since they were first observed in 2016,” Dr Siegelman said.
“These filaments between the larger vortices are relatively small, but they are a key mechanism for maintaining cyclones.”
“It's intriguing that fronts and convection exist and influence Earth and Jupiter, suggesting that these processes may also exist on other turbulent fluid bodies in the universe.”
“Jupiter's enormous scale and Juno's high-resolution images allow us to more clearly visualize how small-scale phenomena like fronts connect with larger-scale phenomena like cyclones and the atmosphere. These connections are often difficult to observe on Earth because they are much smaller and more ephemeral.”
“But the long-awaited new satellite, SWOT, will make observing these ocean phenomena much easier.”
“There's a kind of cosmic beauty in knowing that these physical mechanisms on Earth exist on other planets far, far away.”

A cold, dense cloud in the Milky Way’s interstellar medium is about four to five orders of magnitude denser than its diffuse counterparts, and a team of astronomers from Boston University, Harvard University, and Johns Hopkins University has found evidence that two to three million years ago, our solar system encountered one of these dense clouds, which may have been so dense that it disrupted the solar wind.
Offers othersThe interstellar material through which the Sun has traveled over the past few million years indicates the presence of cold, dense clouds that could have had dramatic effects on the heliosphere. Image credit: NASA/JPL-Caltech.
Most stars generate winds that move through the surrounding interstellar medium.
This motion creates a cocoon that protects the planet from interstellar material. The Sun’s cocoon is the heliosphere.
It’s made up of a constant stream of charged particles called the solar wind, which extends far beyond Pluto, enveloping the planet in what astronomers call a “local bubble.”
It protects us from radiation and galactic rays that can alter DNA, and scientists think it’s part of the reason why life on Earth evolved.
A cold interstellar cloud compressed the heliosphere, temporarily placing Earth and other planets in the solar system outside of its influence, according to a new study.
“Our paper is the first to quantitatively show that there was an encounter between the Sun and something outside our solar system that affected Earth’s climate,” said Professor Merab Auffar of Boston University.
“Stars move, and this paper shows that not only do they move, but they undergo dramatic changes.”
To study this phenomenon, Professor Orpher and his colleagues essentially went back in time and used advanced computer models to visualize where the Sun was located two million years ago, along with the heliosphere and the rest of the solar system.
They also mapped the path of a “localized cold cloud ribbon” system, a series of large, dense and very cold clouds made mainly of hydrogen atoms.
Their simulations showed that one of the clouds near the edge of the ribbon, a “local cold cloud,” may have collided with the heliosphere.
If this had happened, Earth would have been fully exposed to interstellar matter, where gases and dust would have mixed with atomic elements left over from the exploded star, such as iron and plutonium.
Normally, the heliosphere filters out most of these radioactive particles, but without protection they could easily reach Earth.
This is consistent with geological evidence showing increased levels of the isotopes iron-60 and plutonium-244 in the oceans, the moon, Antarctic snow and ice cores from the same period, according to the paper.
This timing also coincides with temperature records indicating a cold period.
“It is rare for our cosmic neighbors outside our solar system to have an impact on life on Earth,” said Harvard University professor Avi Loeb.
“It’s exciting to discover that our passage through dense clouds millions of years ago may have exposed the Earth to much greater amounts of cosmic rays and atomic hydrogen.”
“Our findings open a new window into the evolution of life on Earth and its relationship with our cosmic neighbours.”
“External pressure from localized lynxes of cold clouds could have continuously blocked the heliosphere for hundreds to millions of years, depending on the size of the cloud.”
“But as soon as Earth left the cold cloud, the heliosphere engulfed all the planets, including Earth.”
“It’s impossible to know exactly what effect the cold clouds had on the Earth, such as whether they caused ice ages.”
“But there are other cool clouds in the interstellar medium that the Sun likely encountered in its first few billion years.”
“And we’ll probably encounter many more over the next million years or so.”
The authors are currently working to determine where the Sun was 7 million years ago, and beyond.
Pinpointing the position of the Sun and cold cloud systems millions of years ago is made possible by data collected by ESA’s Gaia mission, which has produced the largest 3D map of the galaxy ever, showing in unprecedented detail how fast stars move.
“This cloud is certainly from our past, and if we passed through something this massive, we would have been exposed to interstellar material,” Prof Auffar said.
“This is just the beginning. We hope this paper opens the door to further exploration of how the solar system was influenced by outside forces in the ancient past, and how these forces may have shaped life on Earth.”

Epitornoceras bardisi It lived in the marine environment of the supercontinent Gondwana during the Late Givetian Stage of the Middle Devonian, approximately 383 million years ago.
“During the Early to Middle Devonian, southwestern Gondwana was characterized by a circumpolar marine environment with a remarkable phase of increasing specificity and the near absence of typical Palaeozoic groups (mainly conodonts, graptolites and stromatoporoids),” Dr. Ninon Allaire By the National University of Córdoba and colleagues.
“One of these families is Ammonite They are extremely rare, with only a few reported finds in deposits from the Early Eifelian to Early Frasnian (393 to 383 million years ago) in Bolivia and Argentina.
Epitornoceras bardisi It was first described as a member of the cephalopod genus in 1968. Tornoceras.
The team's new findings suggest that the species should be reclassified into a separate genus. Epitornoceras.
The genus has been recorded from North America, North Africa and Europe, but this is its first record from South America.
“Epitornoceras “It inhabits North Africa, the Rhine-Bohemian basin and the Appalachian basin,” the paleontologists said.
“Their diversification and acquisition of a wide geographic range occurred after the Taganic biotic crisis in the mid-late Givetian.”
“therefore, Epitornoceras Its occurrence in the southernmost part of West Gondwana during the Late Givean is not surprising, given the well-documented pattern of tropical migration into the circumpolar basins following the Taganic biotic crisis.”

In this study, the authors examined 10 new specimens. Epitornoceras bardisi It was collected from the top of the Chigua Formation in San Juan Province, Argentina.
The study area is located in the Argentine Precordillera, an intraplate fold-fault zone at the southern edge of the Central Andean foreland basin.
“Epitornoceras “Records from Appalachia, Morocco and Europe indicate that the genus is distributed worldwide and diversified after the Taganic biotic crisis in the mid-late Givetian,” the researchers said.
“Its presence at the southernmost tip of western Gondwana suggests a late Givetian migration from the tropics into the cooler Malvinocossan realm.”
“Despite the presence of ammonites from all over the world in the Argentine Precordillera, the coexisting trilobites are Carmoniaceae Additional endemic genera include Bellenopigue“We confirm that the Malvinoxosan (Malvinocafric) realm is still identifiable as a major biogeographic unit during the Late Givettian of southernmost West Gondwana, based on its typical diagnostic elements.”

WASHINGTON — African elephants communicate through calls and respond to their own names, a behavior rarely observed in the wild, according to a new study published Monday.
These names are embedded in the elephants’ distinctive low-pitched vocalizations that carry across the savanna, suggesting that animals with intricate social structures, where family units frequently disband and reunite, are more likely to have individual names.
Ecologist Stuart Pimm from Duke University, who was not involved in the study, remarked, “If you’re managing a large family, you need to be able to call out, ‘Hey, Virginia, come over here!'”
The phenomenon of animals calling each other by name is exceptionally rare in the wild. Humans have names, allowing us to call out to others, and pets like dogs also respond to their names. Baby Dolphin Birds have their own unique names, known as signature whistles, while parrots may also utilize names.
These named species possess the ability to learn and produce distinct sounds throughout their lives, a skill elephants also share.
Biologists conducted research on wild ecology and evolution using machine learning to identify name usage in audio recordings of savanna elephant vocalizations captured in Kenya’s Samburu National Reserve and Amboseli National Park.
By observing the elephants from vehicles, researchers were able to determine which elephants were calling and responding to each other, such as a mother calling for her calf or an older female reaching out to a stray elephant later rejoining the group.
The computer model, analyzing the audio data likely containing names, accurately predicted the addressed elephant 28% of the time, compared to just 8% with meaningless data.
Lead author Mickey Pardo, a biologist at Cornell University, explained, “Like humans, elephants utilize names, but we can’t rely on them entirely as they likely don’t use names in the majority of their vocalizations.”
Elephants incorporate sounds beyond the human hearing range in their calls, leaving scientists uncertain about the specific vocal components that form an elephant’s name.
To validate their findings, researchers played the recordings to individual elephants. The elephants showed heightened responses, including ear flapping and trunk lifting, to recordings containing their names. Some elephants even disregarded vocalizations meant for other elephants.
“Elephants are highly social beings, constantly communicating and interacting, and this system of naming could be a fundamental aspect of their communication abilities,” noted co-author George Wittemyer, an ecologist at Colorado State University and a science advisor for Save the Elephants.
“We’ve provided a glimpse into the elephant’s cognitive world.”
In recent decades, scientists have observed a decrease in atmospheric moisture leading to drying soils, water-starved plants, withering vegetation, and increased forest fires. This phenomenon is linked to wildfire and extreme drought events globally.Despite these observations, the cause of this air dryness remains unclear, and scientists aim to understand it better to enhance climate models for the future of Earth.
Scientists measure atmospheric dryness by comparing the air’s moisture-holding capacity to the actual moisture it holds, known as the “Insufficient steam pressure” or VPD. High VPD in certain areas can lead to soil dryness and surface heating, potentially causing severe droughts.
An international team of researchers examined VPD patterns in Europe to determine if rising levels are natural or a result of global warming. They investigated the difference between current VPD levels and those before industrialization to understand the impact of human activity on VPD changes.
To assess the historical impact of water on Europe’s climate, researchers analyzed Oxygen Isotopes found in tree rings. These isotopes reflect changes in parameters like rainfall and soil moisture influenced by VPD.
Using a Mass spectrometer, researchers analyzed oxygen isotope ratios in tree rings to track changes over time. By counting rings, they could determine the age of trees and obtain valuable data for their study.
The team gathered tree-ring data from various European sites, using Oxygen Isotope Measurements to reconstruct pre-industrial VPD records. They compared these reconstructions with historical data and Earth System Model simulations to understand the factors influencing VPD changes.
Their analysis revealed increasing VPD levels across all European regions studied, with the most significant dryness observed in southern mountainous areas. Industrial influences were found to be a significant factor in current air drying, particularly during summer.
The researchers noted that recent atmospheric drying in Europe is affecting climate and vegetation, impacting plant moisture exchange and growth. This change in atmospheric moisture levels poses risks to human health and the environment, especially in densely populated areas.
In conclusion, the drying of the atmosphere in Europe is attributed to global warming, leading to adverse effects on vegetation, tree growth, and food supplies. Further research is necessary to mitigate these risks and understand the long-term implications.
As winter mornings dawn on Mars, the summits of the planet’s largest volcanoes are covered in frost — another indication of the presence of water on the Red Planet.
We already know that Mars has large deposits of ice in the form of polar ice caps and possibly buried beneath the surface near the equator, but scientists have yet to observe surface water anywhere else on the planet.
Now, Admas Valantinus Valantinas, of Brown University in Rhode Island, and his colleagues found frost, which appears to form only in the mornings during the Martian winter, near the summits of volcanoes in the Tharsis region, including Olympus Mons, one of the solar system’s largest volcanoes. “This is really exciting, because it not only shows how dynamic the Martian water system is, but also that water could be found in varying amounts basically everywhere on Mars,” Valantinas says.
He and his team used a color camera on the European Space Agency’s Trace Gas Orbiter, which studies the Martian atmosphere, to take morning photographs of the icy volcano’s summit and found widespread blue frost. They calculated the surface temperature and found that it was too hot for carbon dioxide to freeze, and that similar-looking frozen carbon dioxide was not the cause.
Ice could form from gases erupting from volcanoes, but if so, do Valantinas and his team expect to see it year-round? Instead, the fact that it only appears during the colder parts of the year makes it more likely that the frost is the result of water vapor in the atmosphere freezing.
Knowing where ice forms on the Martian surface, especially from atmospheric processes, is crucial for accurate weather forecasting, he said. Susan Conway A researcher at the University of Nantes in France, she says we know that polar ice flows into the atmosphere, but we don’t know where it goes. “This is a really cool observation, because now we actually know where it goes.”
Today, we have two questions about fascinating objects that we will share with you along with their answers.
1. Pythagoras’ Cup
Pythagoras, a Greek mathematician and mystic, created a cup with interesting properties:
1) When filled to a certain point, it acts like a regular cup.
2) If you pour above that level, the liquid drains out through a hole in the bottom of the cup.
Can you illustrate how this cup works?
The cup has a simple internal mechanism with no moving parts. It’s a clever metaphor for moderation in life – overflow even slightly, and you lose it all.
Solution:
Cross-section of a Pythagorean cup filled with water. At B, the liquid in the cup can be drunk, but at C, the liquid flows down due to the siphon effect. Illustration: Nevit Dilmen
The cup has a central chamber that fills from the bottom, and when it overflows, a siphon is formed to empty the water. This mechanism is similar to flushing toilets and fabric softener trays in washing machines.
2. A Backwards Old Car
Design a simple mechanism for a toy car with four wheels that moves forward when a string is pulled backward.
Solution:
To achieve this, you need a pulley system as shown in the video. A string is wrapped around a shaft, and when it unwinds, it moves a belt connected to the wheel axle.
We hope you enjoyed today’s puzzles, and we’ll be back in 2 weeks!

Two young elephants greet each other in Kenya's Samburu National Reserve
George Wittemyer
Elephants may be the only animals other than humans that give each other random names, according to a machine learning analysis of recordings.
The analysis revealed that the African savanna elephant (African brown) appears to contain a name-like element that is unique to certain individuals. Moreover, those individuals know their own names and respond more strongly than others when a call addressed to them is played over a speaker.
“For years we've observed that when elephants make contact calls, one elephant in the group will raise his head, listen and respond,” says Joyce Poole. Elephant Voice“And the other elephants seemed to be ignoring him, so we wondered if the call was directed at one particular individual,” said Bryan G. Gregg, a small organization that aims to study and protect elephants.
More than 600 recordings made by Poole and others are currently being analyzed. Michael Pardo Researchers at Colorado State University applied the recordings to analyze elephant calls, including contact calls made when an elephant moves out of sight and greeting calls made when an elephant approaches another. The researchers knew which individual called out to each elephant and responded to each call.
The team's software was able to predict which individual was being spoken to in a quarter of cases, doing much better than chance.
The researchers then played some of the rumbling sounds to elephant pairs, including one that was “named,” and found that the named elephant responded more strongly, approaching the speaker faster, making quicker responses, and emitting more calls than its unnamed counterpart.
Dolphins and some bird species have been known to mimic the calls of calling animals to attract specific individuals. Elephants can learn to imitate soundsHowever, the team found no evidence that the elephants were imitating each other.
In other words, they appear to use arbitrary sounds as names, just like humans do, Poole said.
The analysis revealed whether different elephants share the same names for certain individuals, and each elephant may have its own unique name for the others.
“We have official names, but different people may call the same person by different nicknames,” Poole said. “That could be it. I guess we just don't know yet.”
“This is a very interesting study because there is evidence suggesting that not only do African elephants produce individual-specific vocalizations – which is commonly reported in many species – but, more importantly, that they respond specifically when they hear individual-specific vocalizations made by other elephants,” he says. Daniel Blumstein At the University of California, Los Angeles.
“The idea that elephants can use individually distinct vocalizations to attract specific individuals is novel and provocative, opening the door to a more nuanced understanding of the rich social lives of these animals,” he says.
“I think this result is very reasonable.” Torsten Balsby At Aarhus University in Denmark.
Balsby studies parrots that live in much larger groups, and he notes that learning names would be much harder in a large group of hundreds or thousands of birds. “Mimicking talking to other individuals is a simpler solution that doesn't require prior interaction,” he says.
A 2005 study reported that captive green parrots “vocally label” — or give names to — their peers, Balsby says. But they did so with different versions of contact calls, “so it may not be as arbitrary as elephants',” Balsby says.
Poole believes her work is just the beginning in understanding elephant communication: “Elephant communication has many complex layers that will take time to unravel, so I expect there will be many more exciting discoveries to come in the coming years,” she says.
For example, she thinks elephants might use place names: “When elephants make 'let's go' rumbles to indicate to other elephants in the herd which way they want to go, they may actually be telling them exactly where they want to go,” Poole says.
Analysis of millions of tweets shows the changing meaning of the word “bot”

Calling someone a bot on social media once meant suspecting they were in fact software, but now the use of the word is evolving into an insult for known human users, researchers say.
Many efforts to detect social media bots use algorithms that attempt to identify behavioral patterns that are more typical of the traditional meaning of a bot: automated accounts controlled by a computer, but their accuracy remains questionable.
“Recent research has focused on detecting social bots, which is a problem in itself because of the ground truthing issues,” he said. Dennis Assenmacher The Leibniz Institute for Social Sciences in Cologne, Germany, said it was unclear whether the findings were accurate.
To investigate, Assenmacher and his colleagues looked at how users perceive bots: They looked at how the word “bot” was used on Twitter between 2007 and December 2022 (the social network was renamed X in 2023 after being acquired by Elon Musk), analyzing the words that appeared next to it in more than 22 million English-language tweets.
The researchers found that before 2017, the term was often used in conjunction with allegations of automated behavior, such as “software,” “scripts,” or “machines,” the kinds of things that traditionally fit the definition of a bot. Since that year, that usage has changed.
“The accusation has now become like an insult, it’s used to dehumanize people, it’s used to denigrate people’s intelligence, it’s used to deny them their right to participate in the conversation,” Assenmacher said.
The cause of this change is unclear, but Assenmacher said it may be political in nature. The researchers looked at the accounts of prominent people, such as politicians and journalists, that each Twitter user followed, and classified users as left- or right-leaning. They found that left-leaning users were more likely to accuse other users of being bots, and that those who were accused were more likely to be right-leaning.
“One possible explanation is that the media has reported that right-wing bot networks [2016] “The US elections,” Assenmacher said, “but this is just speculation and needs to be confirmed.”
Illustration of a protection bubble around the sun (yellow dot) and the earth (blue dot)
Harvard Radcliffe Institute
Two to three million years ago, the solar system encountered galactic-scale turbulence and collided with dense interstellar clouds, potentially altering both the Earth's climate and evolution.
Only recently have researchers been able to map the Sun's orbit through the Galaxy, particularly in relation to the relatively dense hydrogen clouds that pass through the interstellar medium, the vast expanse of space between star systems.
the current, Merab Offer A research team from Boston University in Massachusetts has found evidence that one of these clouds, a “local cold cloud ribbon” in Lynx, likely intersects with the Sun's heliosphere.
The heliosphere is a protective cocoon or bubble formed by the solar wind pushing out to the edge of the solar system. Within the heliosphere, the planet is protected from the worst gamma radiation in the galaxy.
The new study proposes that as the solar system passed through the interstellar cloud, the heliosphere retreated from it and moved inward toward the Sun. The researchers think that the heliosphere may have shrunk so much that Earth was outside the protective cocoon provided by the solar wind, perhaps for around 10,000 years.
Merab and his colleagues used the European Space Agency's Gaia satellite to map the location of the dense, cold clouds and the sun's past orbit.
Ofer says the heliosphere's encounter with the cold cloud coincides with deposits of the elements plutonium-244 and radioactive iron-60 in Antarctic ice, deep-sea cores and lunar samples. These elements, which originated from distant supernovae, would have been captured in interstellar clouds and deposited while Earth was outside the heliosphere.
“There are signs of an increase in these elements over the past two years. [million] “The solar cloud record going back 3 million years provides compelling evidence that the Sun did in fact pass through it around 2 million years ago,” Offer says. “The exposure of Earth to a cloud of cold interstellar material and the associated increase in atmospheric hydrogen and radiation almost certainly had a major impact on Earth and its climate.”
Sarah Spitzer The University of Michigan researcher says the paper provides “compelling” evidence that the heliosphere was exposed to a much denser interstellar cloud two to three million years ago. As the solar system passed through that dense, cold cloud, Earth would have been outside the heliosphere and directly exposed to the interstellar environment, she says.
“Understanding this can teach us about the impact interstellar material has had on life on Earth in the past,” Spitzer says, “but it also helps us better understand the impact the heliosphere has on life on Earth today, what would happen if Earth were exposed to interstellar material again in the future, and when that might happen.”
Evan Economo Researchers from Japan's Okinawa Institute of Science and Technology say it's intriguing to consider how encounters in “our nearby space” could have influenced the environment experienced by life on Earth.
“The heliosphere is part of the extended environment experienced by life on the Earth's surface, influencing climate and radiation from space,” he says. “If we had been outside the heliosphere for a period of time, it could have altered the evolutionary trajectory of a wide range of life, including humans. Such connections are highly speculative at this point, but they provide us with new research directions.”
MaMicrosoft didn’t skimp on its Xbox showcase this year. After a string of layoffs and studio closures, the company tried to give gamers what they wanted at its Summer Game Fest on Sunday night, culminating with a 40-minute preview of Call of Duty: Black Ops 6, a massive 300GB download. Continuous online access Even in single-player mode, the textures are streamed from a remote server due to the large amount of textures. As expected, the Xbox version will be available on GamePass from day one, but will not be platform exclusive. The PlayStation version will also be released on the same day, i.e. October 25th.
The game itself is set during the geopolitical turmoil of the early 1990s, including the collapse of the Soviet Union, the Gulf War, and the transition of the US presidency from George Bush to Bill Clinton. As always, the campaign story is an airport-fiction spy thriller, dealing with undeniable CIA operations, covert power struggles, and conspiracies that reach all the way to the very top. Series regular Frank Woods is severely injured and retired from active duty, and is replaced by Troy Marshall, a feckless special forces leader, and Jane Harrow, a shrewd CIA handler. When a mission goes wrong, they are forced to mutiny, recruiting a ragtag team of tech nerds and charming assassins. your Your ass is in danger, sir.
Like most recent Call of Duty titles, Black Ops 6 promises a bit of variety in the way you tackle its campaign missions. Most set pieces, whether they’re set in the glitzy casinos of southern Europe or the tundra of northern Russia, allow for guns blazing attacks or stealth approaches. There are also sequences where players can converse with NPCs to open up new possibilities, such as bribing a senator to grant access to forbidden areas. Familiar faces from the era will make an appearance, including Saddam Hussein, George Bush and Margaret Thatcher, and thankfully Activision has confirmed that at least the latter will be making an appearance. Not a playable option.
Call of Duty titles are typically developed in a quick two years, but with this game, co-developers Treyarch and Raven had double that time. “We had the opportunity to redefine what a Black Ops game is,” says associate design director Matt Scronce. “Every decision we made along the way allowed us to be very deliberate. Previously, each game built on the previous one, but with this game, we really built from the ground up and redefined Black Ops.”
One of the biggest changes to gamefeel is a new system called Omnidirection, which lets players sprint and slide in any direction. “Movement fluidity was a big thing we talked about a lot,” says Yale Miller, Senior Production Director at Treyarch. “That led to a desire to see what we could do.”
One story… Call of Duty: Black Ops 6. Photo: Microsoft
Scrance further explains, “Initially, we tried a 'jug', a quick side step. But when we thought about movement in Black Ops 6, it was all about keeping the player in the flow. It's about fluidity and fidelity, and something like a jug just didn't cut it. So we went back to the drawing board. For over 20 years, Call of Duty has only allowed you to sprint forward. So we looked to the best athletes in the real world: NFL players, NBA players, tennis players — players who can move quickly in all directions.”
Players can now sprint, dive, and slide with 360-degree movement, enabling a wider variety of evasive maneuvers. They can even roll onto their back and under cover, or recreate a classic move from Hong Kong action movies of the time: sliding backwards while shooting forward. Naturally, this system required thousands of new animation frames and motion capture, which wouldn’t have been possible without additional development time.
According to the team, accessibility has also been a key factor. A new intelligent movement system has been introduced, adding crouch, sprint and mantle assist that can be toggled on/off. Players can choose to fully automate jumping over walls and sliding under low obstacles. This was inspired by a variety of games. “We looked at the Forza series with traction control, anti-lock and turn assist,” Scronce said. “Also, mobile games are a good example of this, where you don’t have physical buttons. So what do they do?” The HUD is now also customizable, allowing players to move around on-screen information such as the minimap. This is a feature created with Call of Duty streamers in mind. They often want to add their own camera view in the game and have a hard time deciding where to place it without obscuring important information.
Key multiplayer components have been heavily tweaked, undoing some recent changes. There are 16 new maps, most of which feature the traditional three-lane design, while the Prestige system, which allows seasoned veteran players to show off their prowess with exclusive outfits, accessories, and classified weapons, has returned to the style of previous Black Ops games. Treyarch is also promising a vast arsenal of firearms from the era, with dozens of attachments.

Meanwhile, the regular Call of Duty zombies mode is returning to its roots, which Treyarch first introduced with World at War back in 2008. While the most recent Modern Warfare title introduced a new type of open-world zombie game, Black Ops 6 returns to the older round-based structure, where players work together to survive wave after wave of the undead while unlocking new weapons and exploring confined environments.
The Call of Duty monster truck continues to roll, accompanied by concerns about the appropriation of recent historical events, the glorification of U.S. foreign policy, and an enthusiasm for military-grade weaponry. But like the best blockbuster war movies, the game has its charms, and Black Ops 6 seems to bring some interesting additions to the series’ atmosphere. Which may point to the benefits of giving the studio a bit more time. Scrance said: “Overall, the extra time allowed us to pay more attention to detail and really push the character fidelity, movement, animations, audio, multiplayer maps, and so on, to a point where we can all say this is the best we’ve ever made.”
Xbox has faced some challenges this year. Leaked announcements in January and February about games previously exclusive to Xbox coming to PlayStation and Nintendo Switch caused uproar among fans, leading to concerns about Microsoft’s commitment to Xbox exclusivity. However, only four games remained exclusive, as clarified by Xbox executives. In May, Xbox closed two popular studios, Tango Gameworks and Arkane Austin. Meanwhile, sales of Xbox Series X/S consoles have been slow, with analysts noting a significant increase in PlayStation 5 sales.
The Xbox Games Showcase aimed to turn the tide for Microsoft, featuring big-budget games like Call of Duty: Black Ops 6, a new Indiana Jones game, and the return of Gears of War. Microsoft’s Game Pass service, which offers a monthly library of games, received a $1 billion investment. Following the merger with Activision Blizzard, Microsoft now boasts a vast number of game studios.
Exclusive Xbox games showcased included Perfect Dark and State of Decay 3, among others. The event also featured trailers for upcoming games like Fable, STALKER: Shadow of Chernobyl, and Flight Simulator. The show ended with a reveal of Gears of War: E-Day, set against an alien invasion.
The showcase also featured independent games like Mixtape and FragPunk, offering a diverse range of gameplay experiences. Overall, the event was well-received by Xbox fans and provided a positive outlook for the company after a challenging year. Compared to PlayStation’s game lineup, Xbox’s offerings for 2024 and 2025 appear more robust.
My father, who is 101 years old, was left without a landline or panic button when BT switched his phone service from analogue to digital without warning. BT told me his contract was ending and to contact them about renewing it. I did, but was not informed to contact the panic button provider or that I needed an adapter for his analogue phone to work with the new service. After spending 4 hours on the phone with BT, they finally told me I needed a digital adapter for the phone to function. However, 4 days later, the adapter had not arrived and BT could not expedite delivery. My father, who is blind and has limited hearing, was unable to use his panic button for 5 days until the Careline team helped him.tuberculosis, Birmingham
This incident highlights the difficulties faced by vulnerable individuals when analogue phone lines are transitioned to digital services. Since September, customers renewing or starting contracts have been moved to digital voice, which requires a broadband router. However, digital landlines do not work during power outages and some panic buttons are incompatible, posing risks to vulnerable users.
Critics have raised concerns about the slow rollout of this service, originally set to complete by the end of next year. Following reports of “serious incidents” due to faulty panic buttons, the government has urged providers to extend the deadline. BT has pledged not to switch panic button users unless their equipment is compatible and to provide battery back-up solutions for power outages.
Despite these assurances, your father’s situation suggests that these promises were not fulfilled, potentially putting him at risk. You had to be by his side for five days in case of an emergency.
The Observer contacted BT about your father’s case and, although he was not eligible for their priority repair scheme, they expressed regret for the situation and offered a goodwill gesture to acknowledge his experience.

you Up until about a month ago, the thought of leaving my apartment without headphones plugged into my phone filled me with anxiety. Whether it was a two-minute walk to the store or a two-hour commute where I could hear nothing but my own thoughts and the hustle and bustle of the city, it was enough to send me into a mild state of frenzy.
This obsessive relationship with headphones began earlier this year when a friend of mine, an ambient artist, Lance Laoyen noted that headphones not only disconnect us from the reality of noise pollution, but also continue to distract us under the guise of improving our focus. This conversation sent me into a bit of a spiral of thought that I am prone to fall into, and made me keenly aware of the ubiquity of headphones in our culture and how little attention we pay to them.
In Manchester where I live, it would be hard to find someone in the city centre do not have We wear headphones. Cyclists, commuters, runners, everyone. According to a Statista survey, 30 million people will be using headphones in 2022, the majority of which will be in-ear Bluetooth headphones such as Apple AirPods. By 2027, half of us are predicted to own headphones, the majority of whom will be between the ages of 25 and 45. Many of us choose to listen to something other than the outside world while on the go, whether it’s music, podcasts, or audiobooks, but increasingly I’m beginning to question why.
So in April, I gave up headphones for a month to become more mindful of my relationship with my surroundings, which was addictive to say the least. They were inextricably linked to my daily routine: taking out the trash, exercising, doing the dishes, writing, lunching, sleeping. The only time I ever lived without them was when the battery died. And never, ever, ever, by choice. The anxiety I felt until I was able to charge them should have been enough to at least tell me I was addicted.

Of course, it wasn’t always this way. In 1979, Sony launched the revolutionary Walkman, the world’s first personal listening device. It came with lightweight headphones, and it seemed like a miracle that suddenly music could be carried around with you. You could walk around surrounded by your own soundscape. In this sense, headphones have been very different for each generation, becoming more appealing and addictive with each successive generation. Gen X had the Walkman, while millennials loved MP3 players and iPods, digitizing the personal listening experience and making it even easier to listen to anything, anywhere, anytime. Gen Z, my generation, has grown accustomed to smartphones and streaming services. The desire to listen to something other than the outside world has never been stronger.
The invention of the Walkman didn’t just change the way humans listen to music, it changed the way we interact with our surroundings, with others, and with ourselves. It was a revolutionary change, and the use of headphones Accelerates the progression of hearing loss And more Causes an increase in traffic accidents No one seems to question it because people are distracted.
Someone has been closely studying the collective use of headphones. Michael Bull Bull, a professor of acoustics at the University of Sussex, was one of the first sociological studies of headphone adoption. He believes our addiction to headphones can be explained by a very human motivation: the need for control. This can be broken down into four dimensions. The first is cognitive, which has to do with our ability to control our mood; the second is environmental, which has to do with our power to block out unpleasant noises. Then there’s the physical dimension, which can mean anything from feeling more confident when walking through a crowd of strangers to being able to concentrate without being interrupted by unexpected noises. And finally, there’s social control: headphones allow us to block out everyone unless we choose to let them in.
But Bull points out that this control is a double-edged sword. Headphone users often say they’re free, but he says, “for that to be true, they’re dependent on machines. They’re bound by the economic dynamics of the world and the media they use. It’s a huge paradox: you’re manipulated, but that manipulation creates a sense of freedom.” This resonates with me. I try to be mindful of my relationship to things that seem to permeate our culture but aren’t actually necessary. For example, we feel we “need” smartphones and social media accounts just because they’re ubiquitous, but research consistently suggests that these things are not good for us in the long run. Are headphones different?
This paradox is best exemplified by my desire to control both my cognition and my environment. The two go hand in hand. Living in a city often leaves me disoriented. I witness so much horror that I have no choice but to look away. I walk through Manchester listening to Northern Soul, light on my feet, passing homeless people, completely immersed in my audiotopia. In a way, it seems necessary. It’s painful to see so much sadness every day and not be able to immediately help. So I understand the need to feel in control of my experience, the sense of freedom that comes from blocking it all out. The same can be said about blocking out the noise of industrialization. I understand the argument that headphones can be used as a tool for personal liberation, something Bull found in his research. But true liberation is when the outside world becomes more suited to our needs (and the needs of the natural world, of course).
But you can’t change what you don’t notice. This is what Laoyan told me in a conversation that preceded my experiment. I had never thought before about how our frequent use of headphones and unwillingness to hear the outside world cut us off from reality. He approaches the issue from an environmental perspective. An artist and researcher interested in the impact of noise pollution on the natural environment, he says, “For me, understanding noise pollution is a way of processing the kind of environment we have created and are creating and how it affects us ecologically. These unwanted sounds cause a surge in stress hormones in us and animals, which can be destructive if exposed for long periods of time.” He explains that in places with high levels of noise pollution, there is a high risk of mental and physical breakdown. To ignore it is simply to accept it, but change requires criticism, and to criticize, you need to listen.
Refuses to wear headphones It’s not just about acknowledging the ugliness of the world, but experiencing its beauty. When we block out the city noises that we consider negative, we also block out the noises of the natural world. On the way to the gym, as we walk through a tree-lined street, we hear the birds singing. They are not drowned out by traffic, and we can hear them if we listen carefully. It’s so lovely to hear the whole city. Using headphones, and especially listening to music, is a way to “beautify our experience,” making things more beautiful and enjoyable, explains Bull. But there is joy in the real world, too. It’s great to have. Beauty is all around us, and we just need to notice it.
It’s no secret that the practice of gratitude has many benefits for mental health. Being grateful for what exists outside of your possessions, being grateful for what you have even when you feel like you have nothing, is an infinitely positive thing. So what might be truly liberating is to accept things as they are, and know that while a lot of things are bad, there’s also a lot of good stuff. This is what Laoyan calls “taking back control of your ears,” which he encourages. “There’s something empowering about being able to experience the places we live in through our natural sense of touch and feeling,” he says. “Even if new technologies can enhance or extend the human body, there’s no escaping the fact that we’re intricately intertwined with the world.”
All of this may seem a bit philosophical, and may require a shift in perspective beyond simply leaving your headphones at home, but I noticed tangible benefits in my everyday life. During our email correspondence about the experiment, Laoyan asked me if I’d noticed an increase in my “natural energy.” I’d never thought of it that way, but he was right: everyday chores like washing dishes and hanging out laundry that were previously numbingly boring became relaxing, if not enjoyable.
As a neuropsychologist Dr. Amber Johnston Music stimulates dopamine and the brain’s reward center, she explains. We live in a dopamine-filled society, and many of our favorite technologies contribute to this. If we use music to release dopamine during “boring” tasks, it becomes harder to tolerate boredom. “People who can’t tolerate feeling bored seek out dopamine to relieve discomfort, and music and headphones may be a way to achieve that,” she says. “So actually, if you practice not seeking dopamine and spending time in a state where you feel comfortable with boredom instead, it gradually reduces the amount of additional stimulation you need to get the same dopamine release.”

If I didn’t already know about the social impact of headphones, the bewildered looks on my friends and acquaintances’ faces when I told them I was going to stop using them speak volumes. Most of them lamented the fear of being forced to listen to what other people are saying. And I understand. There is power in being able to easily ignore people, especially when it comes to undesirable behavior like catcalling. But it also closes us off from real interaction. study A survey by audio company Jabra found that UK headphone users wear them for an average of 58 minutes a day, and 38% do so to actively avoid talking to others, leading some researchers to worry that this could be contributing to a culture of isolation and a growing sense of loneliness.
I didn’t immediately start talking to strangers on the street the moment I stopped wearing my headphones, but I did hear more human conversations and felt more connected. But most importantly, I was able to give more of my attention to my loved ones when I was on the phone. I would often use my headphones to multitask while talking to people on the phone – making dinner and navigating on Google Maps. Since I stopped doing this, I’ve noticed that when I talk to friends and family, I can give them my full attention.
Still, I’m not actively against headphones. They can increase focus and productivity, and can be invaluable for people with sensory processing issues. But when I decided not to wear them, something magical happened. I began to calm down. Thoughts didn’t disappear, but they didn’t feel so heavy. They passed me by like cars on the highway. I learned to be present and appreciate the world as it is.
A month after the experiment ended, I still wear headphones from time to time, but they don’t have as much control over me as they
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.
This article addresses the question of what makes up the other 98% of DNA, shedding light on the hidden functions of the dark genome. If you have further questions or want more information, you can reach out on our Facebook and Instagram pages.

Saiga enters a bar. The bartender asks, “Why the long face?” Saiga responds, “A long nose helps me filter out dust in the summer and warm the cold air in winter. Plus, female saigas love big noses.”
Despite its unusual appearance, the saiga antelope has even stranger qualities. In May 2015, during breeding season in central Kazakhstan, a mysterious tragedy struck the saiga population. Over 200,000 saigas, equivalent to 60% of the global species, died from unknown causes.
Conservation efforts had been ongoing to protect the saigas, which had been hunted for their horns in the past centuries, leading to a decline in their numbers. The sudden mass die-off in 2015 shocked experts and led to extensive testing and analysis.
After thorough investigations, it was determined that a strain of bacteria, Pasteurella multocida, had caused the fatal infection in the saigas. This outbreak was possibly triggered by unusual weather conditions, sparking concerns about future die-offs.
Despite these challenges, conservation efforts have been successful in stabilizing the saiga population, with estimates now around 1.5 million. Strict measures like anti-poaching initiatives, habitat protection, and community engagement have contributed to this recovery.
The International Union for Conservation of Nature recently reclassified the saiga from “endangered” to “near threatened,” signaling progress in their conservation. However, researchers remain cautious about the species’ future due to ongoing threats.

While this may be the first general election to be decided using TikTok, it won’t be the first election to be decided on TikTok for the simple reason that British users of the video app are already more likely to vote for Labour.
“The problem is that pretty much everyone on TikTok is already on our side,” a Labour campaign source said. “We need to reach out to the swing vote.”
TikTok’s relatively young user base, and Labour’s commanding lead among young voters, give the app a strange role in this election. There’s no doubt that tens of millions of Britons are consuming election content on the platform — a fertile ground for memes to spread, embarrassing videos to go viral, and passionate political opinions to rally support — and all political parties feel they have to be involved.
But within the Labour party, it is also seen as an unreliable way of conveying Keir Starmer’s core messages on economic and education policy to “Whitby women” and other specific undecided voters who will decide the outcome of dozens of close constituencies across the UK.
Just using TikTok is a strong indicator that someone is already inclined to vote Labour, according to Deltapol research, which found that TikTok users are 31% more likely to vote for Keir Starmer’s party than people of the same age and background who don’t use the video app.
“This allows us to conclude that people who use TikTok are more likely to vote Labour,” said Mike Joslin, a veteran digital campaigner who commissioned the research for artificial intelligence start-up Bombe. “Other channels give them more control in reaching undecided voters.”
TikTok’s cultural influence in the UK is undeniable, with 45% of UK internet users spending an average of 28 minutes a day on the app, according to the British Communications Authority. If you’ve ever seen the queues outside a TikTok-inspired restaurant or shop, you know the app can have a huge real-world impact and change behavior. While the typical user is Gen Z, its audience is actually ageing, with much of its recent growth coming from people in their 30s.

Joslin said the app has become “essentially television,” with users endlessly scrolling through videos without necessarily engaging. “You can reach 10 million people, but what impact does that have on their actual willingness to vote? It’s more of a tool for mobilizing voters than necessarily a tool for persuading voters.”
One of the biggest challenges is that TikTok employs an opaque recommendation algorithm that is extremely difficult for political activists and journalists to monitor, meaning that just determining which videos are popular focuses on what political parties are doing on their official accounts, even though much of the conversation is taking place elsewhere and is largely invisible.
Older social networks like X and Facebook were built on the concept of following individuals and sharing content, such as links to news articles, in a way that could be tracked and monitored. TikTok is centered around powerful algorithms that identify users who are likely to enjoy specific content and serve them appropriate video streams.
The end result is highly unpredictable and not necessarily useful for political campaigns: if an ordinary person with no followers produces a particularly compelling political video (such as the 1 million people who watched David Cameron through a Ring doorbell during an election campaign in Hampshire), it can be more effective than a carefully crafted official post by an official channel (such as the 40,000 people who watched Rishi Sunak answer a question about agriculture on the official Conservative party account).
According to one Labour campaigner, the aim of the party’s TikTok strategy is to encourage young people to watch videos (e.g. A post comparing Rishi Sunak to a Magic the Gathering card) and post it to a family WhatsApp group. This way, they say, TikTok content can actually reach swing voters. “The strategy isn’t to target young people, but to connect with friends and family by sharing outside the platform.”
Dinosaurs were once thought to be big and fearsome creatures, but our understanding of them has changed over time. As we learn more about them, we realize how incorrect our early assumptions were.
Here are seven significant ways our understanding of dinosaurs has evolved…
1. Tyrannosaurus Rex
In 1902, paleontologist Barnum Brown discovered a massive pile of bones in Hell Creek, Montana. These bones belonged to a muscular animal that walked on its hind legs and stood several meters tall. Its skull and jaws portrayed a formidable predator.
The discovery was exhibited at the American Museum of Natural History in 1905, astounding the audience. This monster was called Tyrannosaurus Rex, known as one of the largest and most powerful carnivorous animals to have ever lived on Earth.
Further studies have revealed that T. rex had a large brain, keen senses, and likely had some feathers on its body.

2. Iguanodon
In 1822, Gideon Mantell presented fossilized teeth found in Sussex to the Royal Society. These teeth were later recognized as belonging to a dinosaur called Iguanodon. This dinosaur roamed the earth with its spiked hands for self-defense.

Elasmosaurus, named in the 1860s, had the longest neck of any animal that ever lived. Its skeleton baffled paleontologists for years until a more complete understanding was reached.
5. Stegosaurus
When Stegosaurus bones were first found in the 1870s, they were thought to belong to a strange aquatic creature due to the large vertical plates on its back. Later discoveries revealed a different picture, with some suggesting the plates were for display or thermoregulation.
Previous depictions of Stegosaurus were unclear on the plate – Image credit: Alamy
6. Ichthyosaur
Mary Anning’s discovery of Ichthyosaur fossils in 1811 led to the recognition of these creatures as extinct aquatic reptiles. This marked an important milestone in paleontological understanding.

7. Pterosaur
In 1784, the first Pterosaur fossil was discovered, leading to the recognition of these creatures as flying reptiles. They were not dinosaurs but were closely related and the first bony animals to evolve powered flight.

TThe dark mouth of a well has always been a fascinating focal point of human fascination. It is seen as both the source of life-sustaining water and the entrance to dangerous secrets. Our fables are replete with scenes in which curiosity gets the better of crying children, who gaze up into a halo of light that is forever damp and out of reach. Animal Well is an indie game seven years in the making that throws you into one of Twilight’s labyrinths, a complex of caverns constantly dripping and darting with furry, luminescent creatures. The goal is unstated but clear: explore, map, emerge. It’s an instantly engrossing quest.
You play as a shapeless blob, not the most ambitious cipher ever, but what it lacks in limbs and such it makes up for in courage and ingenuity. At first, all you can do is bravely leap between rocks and scaffolding, but over time you’ll gain new tools, gadgets and abilities, gaining access to previously inaccessible passages and tunnels. Bit by bit, the map will fill up as you explore deeper into the cave system.
Dangling lightbulbs swaying in the underground breeze illuminate the surrounding scenery, but you have to look closely at each scene to notice the half-submerged gears, pulleys, and levers that open up the world. Animal Well It’s a game about exploration, with puzzles and secrets, where your ingenuity matches that of the game designers. And when you find the solution, everything falls into place, the world opens up a little, you can dive a little deeper, and that’s when you feel the thrill of it all. Animal Well Excellent.
In an era when major video game companies are focused on developing video games with leisure-time, sport-like features — seasons, passes, endless matches — what a treat to see a game this complex and restrained come along. This is a perfectly crafted contraption with a beginning, middle and end, designed to inspire joy and build culture — thankfully not shareholder value.
Slowing down isn’t typically a priority for runners. From elite athletes to casual runners, the focus is usually on speed, personal records, competition, and pushing limits.
However, the concept of slow running has gained popularity recently. It’s not just a trend promoted by social media influencers, but also endorsed by coaches, runners, and scientists.
What are the benefits of running slowly?
The idea is that running at a slower pace can actually yield faster results in terms of exercise benefits.
“For example, running slowly can lower your resting blood pressure and strengthen your heart,” says Professor Dan Gordon. “It still challenges the body but without the need for excessive stress to achieve cardiovascular improvements,” adds Jonathan Myers, an exercise physiologist at Anglia Ruskin University.
Running slowly is typically defined as a pace where you can comfortably hold a conversation. It’s an effort level of 4 or 5 on a scale of 1 to 10, with 10 being a sprint. This type of exercise, known as “Zone 2 exercise” in sports science, is considered to be a sweet spot for promoting longevity and overall health.
A study in Copenhagen found that light and moderate joggers had lower mortality rates than non-runners and intense runners. Vigorous joggers did not show significantly different mortality rates from non-runners.
Running slowly is beneficial for heart health, enhances metabolic functions, and improves mental well-being. It can prevent metabolic diseases, improve insulin sensitivity, and boost mitochondrial density in cells, leading to improved energy utilization.
Improved mental and physical health
Slow runners experience faster recovery, reduced risk of overtraining-related fatigue and injuries, and generally feel better overall.
“Slow running has a positive impact on mental health and social well-being,” says Gordon. “It allows for social interactions, which can motivate individuals to stay active and enjoy the process without pressure to perform.”
What we’re starting to realize is that you don’t need intense stress on your body to see cardiovascular benefits.
Gordon believes promoting slow running in groups can encourage more people to stay active consistently, as the social support can enhance motivation and enjoyment of the activity.
More Gains, Less Pain
Contrary to the belief that speed is essential for improvement, researchers suggest that slow running can yield significant results. Elite runners, for example, often perform majority of their training at a slow pace to build a strong aerobic base and enhance cardiovascular efficiency.
This concept of an “Aerobic Base” emphasizes the importance of improving cardiovascular capacity to enhance overall running performance. By running slowly, you can increase endurance, speed, and efficiency while reducing exertion.
In summary, slowing down not only improves longevity but also enhances running abilities in the long run.

The Summer Game Fest this year was lacking major announcements but featured plenty of indie titles. One noteworthy reveal was the announcement that Civilization 7 is set to launch in 2025.
This legendary strategy simulation series, which first debuted in 1991, has not seen a new release in eight years. Publisher 2K accidentally leaked the news. Along with this announcement, fans were treated to a video of designer Sid Meier showcasing new projects.
Meier expressed his excitement for fans to witness Civilization VII, the culmination of three decades of strategic innovation. The game will be available on PC, PlayStation, Xbox, and Switch, but the exact release date is yet to be revealed.
Harry Potter, LEGO Horizon Adventures, etc.
The event kicked off with host Geoff Keathley addressing the challenges faced by the gaming industry in the past year. Among other announcements, LEGO Horizon Adventures was officially unveiled, a cooperative game featuring protagonist Aloy.
Additionally, Warner Bros. and Unbroken Studios announced Harry Potter: Quidditch Champions, a simulation of the magical sport set to release on September 3 for various platforms.
New trailers for Monster Hunter Wild, Slitterhead, and Dune Awakening were also released, building up anticipation for these epic games. Ubisoft teased Star Wars Outlaws, featuring familiar characters from the Star Wars universe.
Indie Summer
The indie developers were the spotlight of the show, showcasing games like Cuffbust and Wonder Stop. Exciting new projects from studios like Nomada Studio were also presented, offering unique and innovative gaming experiences.
Big companies like Blumhouse and InnerSloth announced their support for indie studios, unveiling new games and funding opportunities. Despite the lack of major triple-A announcements, the focus on indie developers brought hope for the future of gaming.
A silent colossus lurks off the Pacific coast, threatening hundreds of miles of coastline with tsunamis and devastating earthquakes.
For decades, scientists have been warning about the possibility of a major fault line breaking off from the Cascadia Subduction Zone, a megathrust fault that runs offshore along the coast from northern Vancouver Island to Cape Mendocino in California. The next time this fault, or parts of it, breaks, it could upend life in Oregon, Washington, and Northern California.
Of particular concern are signs of great earthquakes in the region’s geological history. Many researchers have been pursuing clues about the last “big quake,” a magnitude 8.7 earthquake that occurred in 1700. They have pieced together this history using centuries-old tsunami records, Native American oral histories, physical evidence of saltwater-flooded ghost forests, and limited maps of faults.
But no one had ever comprehensively mapped the fault structure until now. The study published Friday A paper published in the journal Science Advances describes the data collected during a 41-day research voyage, in which the ship dragged a mile-long cable along the fault, listening to the ocean floor and piecing together images.
The team completed a detailed map of the subduction zone, stretching more than 550 miles to the Oregon-California border.
Their work will give modelers a clearer picture of the impact of a megaquake in the region — a megaquake that occurs in a subduction zone, where one plate pushes under another — and give planners a more detailed, localized view of the risks to Pacific Northwest communities, which could help redefine earthquake-resistant building codes.
“It’s like wearing Coke-bottle glasses, and when you take them off, they give you the correct prescription,” said lead author Suzanne Calbott, a marine geophysicist and research professor at Columbia University’s Lamont-Doherty Earth Observatory. “Before, we only got very blurry, low-resolution images.”
Scientists have discovered that subduction zones are much more complex than previously thought. They are divided into four segments, and researchers believe each segment could rupture independently or simultaneously. Each segment has different rock types and different seismic properties, which means some segments may be more hazardous than others.
Earthquake and tsunami modelers are beginning to assess how the new data might affect earthquake scenarios in the Pacific Northwest.
Kelin Wang, a research scientist with the Geological Survey of Canada who was not involved in the study, said her team, which focuses on earthquake hazards and tsunami risk, is already using the data to make predictions.
“The accuracy and resolution is truly unprecedented, and this is an incredible dataset,” said Wang, who is also an adjunct professor at the University of Victoria in British Columbia. “This will allow us to better assess risk and inform building codes and zoning.”
Harold Tobin, co-author of the paper and director of the Pacific Northwest Seismic Network, said the data will help fine-tune predictions, but it won’t change the untenable reality of life in the Pacific Northwest.
“It could potentially produce earthquakes and tsunamis that are comparable in magnitude to the largest earthquakes and tsunamis the Earth has ever seen,” said Tobin, who is also a professor at the University of Washington. “It looks like Cascadia could produce an earthquake of magnitude 9 or a little less or a little more.”
A quake of that magnitude could cause shaking for about five minutes and generate a tsunami up to 80 feet high, damaging more than 500,000 buildings. According to emergency planning documents:.
Neither Oregon nor Washington are adequately prepared.
To map the subduction zone, researchers at sea used active seismic imaging, a technique that sends sound waves into the ocean floor and processes the returning echoes, a method often used in oil and gas exploration.
They towed more than nine miles of cables called streamers behind the ship and used 1,200 hydrophones to capture the returning sounds.
“This will give us an idea of what the conditions are like underground,” Calbot said.

Trained marine mammal spotters would alert the crew to any signs of whales or other animals. Sounds produced by this type of technology could be disruptive and potentially harmful to marine life.
Calbot said the new research makes it even clearer that the entire Cascadia Fault won’t rupture all at once.
“The next earthquake in Cascadia could rupture just one of these segments, or it could rupture the entire boundary,” Calbot said, adding that some individual segments are thought to have the potential to produce a quake of at least magnitude 8.
Over the past century, scientists have observed only five earthquakes of magnitude 9.0 or higher, all of which were the kind of giant quakes predicted in the Cascadia subduction zone.
Scientists have compiled the latest insights into the 1700 Cascadia earthquake, based on records of an unusual orphan tsunami that was not preceded by any shaking in Japan.
“It would take a magnitude 8.7 earthquake to send a tsunami all the way to Japan,” Tobin said.
Those in Japan who recorded the event had no idea that the earthquake occurred across the ocean in what is now the United States.
Right now, the Cascadia subduction zone is eerily quiet. At other subduction zones, Calbot says, scientists often observe small, frequent earthquakes that make it easier to map the region. But that’s not the case here.
Scientists have a few hypotheses as to why. Wang said the region could be getting quieter as stress builds on the fault, and that time may be approaching.
“The interval between big earthquakes in this subduction zone is about 500 years,” Wang said. “It’s hard to know exactly when it will happen, but it’s certainly quite late compared to other subduction zones.”
Two teeth from the newly identified ancient ape Buronius manfredschmidi, viewed from multiple angles
Böhme et al., 2024, PLOS ONE, CC-BY 4.0
A small, herbivorous ape may have lived in Western Europe 11.6 million years ago. Smaller and lighter than any great ape known to date, the newly discovered 10-kilogram (22-pound) primate was probably a skilled climber that ate leaves, researchers say. Madeline Boehme At the University of Tübingen, Germany.
“This is a fairly small primate,” she says, “but it's different from all the known fossils and certainly different from all the modern great apes we've known so far.”
About 15 million years ago, during the Miocene, hominoids (great apes) became rare in Africa and more abundant in Europe. Hominoids sometimes shared habitats with other primates, including apes and pliopithecoids, extinct relatives of Old World monkeys, but hominoids do not appear to have coexisted with each other in Europe.
In 2019, Boehme and his colleagues reported the discovery of 37 bones at the Hammerschmiede site in Bavaria that appear to belong to an early, bipedal ape dating back 11.6 million years ago, which they named “hominoid.” Danubius Guggenmosi.
During the excavation, Boehme was surprised to find two small ape-like teeth and a kneecap in the same sedimentary layer. Danubius fossil.
“We kept saying, 'What is this?'” she says of these tiny fossils, “and we concluded that this is clearly something new.”
The fossils are too old for DNA analysis, Boehme said, so the researchers took detailed measurements of the juvenile's 7-millimeter-long molar and 16-millimeter-wide kneecap, as well as a fragment of a premolar that they believe to belong to a young adult. They also calculated the thickness of the enamel and took microscopic CT scans of the teeth.
The gorilla-like thin enamel suggests they probably ate soft foods like leaves, Boehme said, and the shape, thickness and ligament attachment sites of the kneecap are similar to those of arboreal primates, suggesting the apes were good climbers.
Researchers look at new ape Bronius ManfredschmidyThe fossil, named after the medieval name of the nearby Hammerschmiede site, was discovered by dentist Manfred Schmidt, who has been collecting fossils at the site since the 1970s.
Lack of competition for resources Bronius and Danubius Apes can coexist, says Boehme – Danubius They are thought to have eaten tough foods such as nuts and meat, and the team can't rule out the possibility that great apes, which could have been up to three times as heavy, may have preyed on smaller species, she added.
But these three fossils alone may not be enough to reach such a “big” conclusion, the researchers say. Sergio Almesia It is on display at the American Museum of Natural History in New York City. “Small fossil elements may date to infancy. Danubius “The teeth definitely look like baby teeth. [baby teeth]. “
He also thinks the kneecap may represent the same species as the tooth: “It has been suggested that it belongs to a juvenile individual, but its size overlaps with the lower range of adult orangutans.” [which are much larger apes]” says Almesija.
Clement Zanolly A researcher from the University of Bordeaux in France also has doubts: “I'm not sure whether the teeth, especially the molars, belong to a hominoid or to another primate superfamily, a pliopithecoid.”
Boehme and his colleagues say their comparison rules out the possibility that the tooth is a milk tooth or a pliopithecoid tooth.
In any case, the fact that the two primate species shared the same habitat and possibly even interacted with each other is a “fantastic discovery,” Zanolli said, “and it reinforces the idea that Europe at that time was a luxurious and comfortable place for primates to evolve.”
Horses revolutionized human history by increasing mobility, but the timeline between their domestication and widespread integration as a form of transportation remains debated.
Genetic evidence suggests that modern domestic horses emerged around 3000 BC in the steppes of western Eurasia, including an area inhabited by nomadic peoples known as the Yamnaya.
According to some accounts, the Yamnaya people migrated to Europe on horseback.
The earlier appearance of a different lineage of domesticated horses (probably used for milk) in association with the Botai culture of Central Asia (context: c. 3500 BC) also adds confusion.
To explore the possible timing of domestication, Dr. Ludovic Orlando of the Toulouse Centre for Anthropology and Genomics, Dr. Pablo Librado of the Barcelona Institute of Evolutionary Biology and their colleagues analysed the genomes of 475 ancient horses and 77 modern horses.
“I started working with horses about 10 years ago, and at the time there were only a few ancient genomes,” Dr. Librado said.
“With this new study, we now have hundreds of specimens. The increased resolution over Central Europe, the Carpathians and the Transylvanian Basin was particularly important, as this region was at the heart of the ongoing debate about a large-scale horse-driven migration out of the steppes around 5,000 years ago, or maybe even earlier.”
The researchers found that around 2200 BC there was a clear change in horse breeding practices (including the introduction of inbreeding), which resulted in the replacement of almost all horse bloodlines with modern livestock bloodlines.
This expansion was preceded by a domestication bottleneck (starting around 2,700 BC) that shortened generation times (related to the age at which horses breed) and made it easier to breed new domestic horses.
Previous studies have suggested that the Yamnaya migration occurred between 3,300 and 2,600 BCE.
The timing suggested by this study is therefore inconsistent with the hypothesis that the Yamnaya-related steppe peoples were accompanied by large herds of modern domesticated horses.
The authors also found evidence of domestication of the Botai horse, including shortened generation times, which means that horse domestication may have occurred in some areas before 2700 BC, but did not lead to widespread migration of horses.
“One question I've long wondered about is the scale of production: how was it possible to suddenly keep such large numbers of horses from a relatively small livestock area to meet growing global demand by the turn of the second millennium BC?” Dr Orlando said.
“Now we have the answer: breeders have controlled the reproduction of the animals so well that the time interval between two generations has been almost halved.”
“Simply put, they were able to speed up the breeding process and essentially double their production rate.”
“Our methodology for measuring temporal changes in generation time has great potential,” Dr. Librado explained.
“This adds a new method to the archaeozoological toolkit for monitoring the development of managed breeding in a range of livestock species beyond horses.”
“But it could also help shed light on generation intervals in our hunter-gatherer ancestors and how these intervals evolved alongside changing lifestyles and significant climatic changes.”
“Our evidence supports two stages of domestication of the horse,” Dr Orlando said.
“The first attempts, which occurred around 5,500 years ago, were aimed at addressing the decline of horse populations and providing food for people living on the steppes of Central Asia.”
“The domestic horse as we know it emerged from a second period of domestication about 4,200 years ago.”
“This allowed high-speed travel for the first time and truly changed human history.”
Is removing carbon dioxide from the atmosphere one of the best weapons against climate change? Climeworks, a Swiss company, believes so, as they have recently unveiled the world’s largest direct carbon capture and storage plant.
The new facility, Mammoth, will be located in Hellisheiði, Iceland, and will be nine times larger than Climeworks’ original plant, Orka. Mammoth’s goal is to extract 36,000 tonnes of carbon dioxide from the atmosphere annually, equivalent to removing approximately 8,600 cars from the road.
Powered by renewable energy, Mammoth captures carbon dioxide from the air and transports it to a facility where it is combined with water and injected deep underground. The carbonated water reacts with porous basalt rocks, transforming them into solid carbonate minerals that securely sequester the carbon underground for thousands of years.
The Mammoth Power Plant aims to have 12 of its 72 heat collection containers installed and fully operational by the end of 2024.

Swiss mechanical engineers and Climeworks founders Christoph Gevaert and Jan Wurzbacher introduced the concept of a direct air capture plant in 2015. Since then, the company has expanded rapidly, with Orka and Mammoth just the beginning of their efforts to reduce atmospheric carbon levels.

By expanding with facilities like Orka and Mammoth, Climeworks aims to achieve megatonne-scale carbon removal capacity by 2030 and gigatonne-scale capacity by 2050.
While the impact on atmospheric carbon levels remains uncertain, the technology is expected to play a significant role in shaping the planet’s future over the coming decades.

The discovery was made possible by ESA’s Gaia spacecraft, which is mapping more than a billion stars across the Milky Way galaxy and beyond, tracking their motions, brightness, temperature, and composition.
This image visualizes the Milky Way and its surrounding halo of stars. New Gaia data reveals that the wrinkles seen in the Milky Way are likely the result of a dwarf galaxy colliding with the Milky Way about 2.7 billion years ago.

The Milky Way galaxy has grown over time as other galaxies have approached, collided, been torn apart, and been swallowed up.
Each collision still sends ripples through different groups of stars, influencing their movements and behavior in space.
One of Gaia’s goals is to study these wrinkles to unravel the history of our Milky Way galaxy. It does this by pinpointing the positions and motions of more than 100,000 stars close to Earth, a tiny fraction of the roughly 2 billion objects it observes.
“As we age, we tend to get more wrinkles, but our research shows that the opposite is true in the Milky Way – it’s like a cosmic Benjamin Button, and it gets less wrinkled over time,” said Dr. Thomas Donlon, an astronomer at Rensselaer Polytechnic Institute and the University of Alabama.
“By looking at how these wrinkles fade over time, we can trace when the Milky Way last experienced a major collision — and it turns out this happened billions of years later than we thought.”
The Milky Way’s halo contains many stars with unusual orbits, many of which are thought to have been incorporated into the galaxy in an event that astronomers call the last great merger.
As the name suggests, this is the last time the Milky Way has experienced a significant collision with another galaxy, which is proposed to have been a giant dwarf galaxy that smothered the Milky Way with stars passing very close to the center of the Milky Way.
Astronomers estimate that the merger occurred between 8 and 11 billion years ago, when the Milky Way was still in its infancy, and is known as Gaia-Sausage-Enceladus.
But data from Gaia’s Data Release 3 suggests that another merger could have resulted in the unusually behaving star.
“For the stellar wrinkles to be as clear as we see in the Gaia data, the stars would have had to have appeared on Earth less than 3 billion years ago — at least 5 billion years later than previously thought,” said Dr. Heidi Jo Neuberg, also of Rensselaer Polytechnic Institute.
“Every time a star passes back and forth through the center of the Milky Way, a new stellar wrinkle forms.”
“If they had merged with us 8 billion years ago, there would have been so many wrinkles next to each other that we wouldn’t be able to see them as separate features.”
This discovery suggests that these stars did not result from the ancient Gaia-Sausage-Enceladus merger, but must have arisen from a more recent event called the Virgo radial merger, which occurred less than 3 billion years ago.
“The history of the Milky Way is currently being constantly rewritten, thanks in large part to new data from Gaia,” Dr. Donlon said.
“Our image of the Milky Way’s past has changed dramatically since even 10 years ago, and I think our understanding of these mergers will continue to change rapidly.”
“This finding that most of the Milky Way galaxy joined Earth within the last few billion years is quite different from what astronomers previously thought.”
“Many prevailing models and ideas about the growth of the Milky Way predict that a recent head-on collision with a dwarf galaxy of this mass would be extremely rare.”
“The Virgo radial merger likely pulled in a group of other small dwarf galaxies and star clusters, all of which joined the Milky Way at about the same time.”
“Future exploration will reveal which of these small objects previously thought to be related to the ancient Gaia sausage Enceladus are in fact related to the recent Virgo radial merger.”

“Can you hear me now?” Keith Gill began the broadcast. “I kind of forgot how to do it.”
In 2021, an influencer known as Roaring Kitty led a retail investor movement that sparked an extraordinary surge in shares of the embattled video game chain GameStop, convulsing Wall Street, and Mr. Gill became an internet star and testified before Congress about his bullish stance on the stock.
And then he disappeared. For years after the stock market turmoil began, Gill remained silent online, even as a Hollywood movie was made about his battle with the financial establishment.
Last month, a series of cryptic social media posts suggested Roaring Kitty had woken up from a three-year slumber, reigniting a volatile rally in GameStop shares. But they raised more questions than they answered.
Hundreds of thousands of viewers were waiting when Gill reappeared on YouTube today, but those tuning in hoping for an explanation were in for a frustrating 50 minutes.
The first time GameStop's stock price surged in 2021 was Loss-making companiesThree years later, the company is still unprofitable and struggling to find its place in the modern gaming industry.
Its latest earnings report, released just before Roaring Kitty was released, revealed a steep decline in sales since the start of the year. GameStop also Confirmed Plan The company plans to take advantage of the recent surge in its share price by selling up to an additional 75 million shares.
“We will not be holding a conference call today,” GameStop said in a brief press release, without explaining any reasons for the poor performance. The company's shares fell by about 25 cents and trading was halted multiple times.
Retailers weren't ready for the market, but one enthusiastic follower was happy to oblige. Gill reappeared with his arm in a sling, his head bandaged, his face in a bandage, and sunglasses. With the sound of life support machines ringing in the background, he pretended to be dead.

“Yeah, that was close,” he laughed, thanking the audience for bringing him back to life, even as the stock price of GameStop Corp. showed up in the background and looked far from healthy.
Gill was keen to dispel the rumours: “This is me, by the way,” he said, stressing that he controls his own dealings and social media accounts and does not work with anyone else.
Despite speculation that he might offer new information to explain his confidence in the fading retailer, Gill clarified that he had “no concrete plans,” instead rambling on about movie memes, playing with a Magic 8 Ball and thanking his followers for their well wishes ahead of his birthday.
“It's been a few years now. How are you all?” he said. “I'm so glad to be back.”
Gill reiterated his long-held belief that GameStop's management would one day reinvigorate the chain in some way, but this is hardly a new revelation. Gill hastened to add that while it's not a guarantee, Ryan Cohen, the billionaire entrepreneur who heads the company, “seems to be doing the right thing.”
“In this case, absence of evidence is not evidence of absence,” he argued about GameStop's recovery, but the company's shares continued to fall when it became clear that his livestreams would not be covering any significant news.
“I haven't said anything right,” he continued. The stock price had fallen 40% since the start of the day. “I'm just saying something wrong. Where's the eject button?”
After a while, he found and pressed it. “A toast to everyone,” Gil said, taking a swig of his beer, and finished. “We'll see what happens next.”
High temperatures occur in Joshua Tree, California on June 5, 2024

Mexico has been hit by a severe heat wave caused by a massive heat dome that has been sweeping across the country for weeks and is now spreading north into the southern United States, causing extreme temperatures across a wide area.
What is a Heat Dome?
Heat dome is not a clearly defined scientific term, but is used by many weather forecasters. American Meteorological Society Define it “A mass of very hot air that occurs when high pressure in the upper atmosphere prevents warm air below from rising.” High pressure causes the air to warm up as it descends, resulting in clear skies. – Clouds form in the opposite situation, when rising air cools and water droplets condense..
These high pressure conditions mean more sunlight, which leads to more warming, drier soil, less evaporation, and fewer clouds and rain. This positive feedback means that the longer the heat dome stays in one place, the hotter and hotter it gets. Heat domes cause heat waves, but heat waves can also happen without them.
What causes a high pressure system to shut down?
The jet stream is a fast-moving band of wind in the upper atmosphere that normally helps move weather systems along the Earth's surface. But sometimes large loops can form in the jet stream, which can result in weather systems getting trapped in the loop. These blocking patterns can lead to extreme cold, extreme rain, or, in the case of a heat dome, extreme heat.
Temperature records were broken in several North American cities during the 2021 Heat Dome.

What is the lifespan of a heat dome?
It may last from a few days to a few weeks. For example: Extreme Heat Dome The storm lasted for almost a month across Canada and the northwestern United States in 2021. During this time, temperatures in British Columbia reached nearly 50 °C (122 °F), the highest temperature ever recorded in Canada.
Are heat domes becoming more popular because of global warming?
Generally, heat waves Becoming more frequent Although it is caused by climate change, most studies have not focused on heat waves caused by heat domes. There is much debate about how global warming will affect the planet. Block pattern that confines the heat dome in place. Research in 2023 They concluded that northwestern North America will experience an increase in “summer heat dome-like standing waves.”
Is the heat dome getting hotter because of global warming?
Yes, that is true. The world is currently about 1.5°C warmer than it was before the industrial revolution, so if a heat dome were to form today, surface temperatures could be higher than they were before. For example, One study concluded The extreme heat dome temperatures recorded in Canada in 2021 would have been “virtually impossible without anthropogenic climate change.” There is also evidence that the intensity of heat domes is outpacing the warming trend, suggesting that climate change is amplifying the intensity of heat domes.“The intensity of high temperatures associated with thermal dome-like atmospheric circulation is increasing faster than background global warming, both historically and in future projections,” it said.
