Ovaries contain hundreds of thousands of underdeveloped eggs, held in a kind of suspended animation. Each month, one matures and is released—potentially to be fertilized by sperm and create an embryo. For the first time, scientists say they have managed to take eggs from the ovaries of transgender men and get them ready for fertilization in a process completed entirely outside the body. The achie
Using new analyses, scientists have just found the last two of the five informational units of DNA and RNA that had yet to be discovered in samples from meteorites. While it is unlikely that DNA could be formed in a meteorite, this discovery demonstrates that these genetic parts are available for delivery and could have contributed to the development of the instructional molecules on early Earth.
It's official: Twitter has agreed to allow a takeover by Tesla and SpaceX CEO Elon Musk, the richest person in the world — a watershed moment in the history of social media, as well as a puzzling new twist for a billionaire best known for rockets and electric cars. The transaction is worth roughly $44 billion, a 38 percent premium compared to the stock price the day before Musk started investing
Spotted A massive ten foot giant squid washed ashore in western Japan, giving an ultra-rare glimpse of one of the biggest cephalopods known to lurk the deep sea — and likely the first time a live specimen has ever taken into captivity . According to Japanese newspaper The Mainichi , the squid was miraculously found alive despite being a long way from home. It has since been transported to a local
Tesla and SpaceX CEO Elon Musk may soon be the proud new owner of the social media platform Twitter. On Monday, news emerged that Twitter's board had decided to accept Musk's offer of roughly $44 billion to buy the company outright. Musk, for his part, has framed the takeover as an effort to promote free speech on the platform. "Free speech is the bedrock of a functioning democracy, and Twitter i
Research at Lund University in Sweden has found a new way to create nano-sized magnetic particles using ultrafast laser light pulses. The discovery could pave the way for new and more energy-efficient technical components and become useful in the quantum computers of the future.
As educators and industry mull strategies for attracting more young adults to math-oriented professions, a new study in the journal Child Development suggests that children's early experiences doing math homework and activities with their parents shape their motivation and achievement.
Researchers at Tampere University have successfully developed a novel optical fiber design allowing the generation of rainbow laser light in the molecular fingerprint electromagnetic region. This new optical fiber with a self-cleaned beam can help in developing applications for, for example, pollutant tagging, cancer diagnostics, environmental monitoring, and food control. The finding was publishe
Researchers from the Oden Institute and Jackson School of Geosciences have developed an improved model for planet-wide groundwater flow prediction on Mars that is not only more accurate but, according to its author, more elegant too.
A new study found that when red tides began in early summer and continued into the fall, low oxygen areas—or dead zones— were more likely to also occur. This study by scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science, and NOAA collaborators is the first study to link low oxygen—or hypoxia—to red tides across the west coast of Florida and offers new informati
If our planet Earth is to continue feeding us in the future, rich countries must significantly reduce their meat consumption — ideally by at least 75 percent. The study reviews the current state of research on various aspects of meat consumption. In addition to the effects on the environment and climate, these include health and economic effects.
Vacuum Tubes One thing we know about SpaceX and Tesla CEO Elon Musk? He's a glutton for punishment. Case in point, as he attempts to acquire Twitter, the billionaire says his Boring Company tunnel-drilling venture is attempting to "build a working Hyperloop" in the "coming years." It's been quite a while since Musk last talked about the Hyperloop, a futuristic transportation system that would sho
T o be honest , I still can't believe this happened. Earlier today, Twitter accepted Elon Musk's offer of $44 billion to buy the company and take it private. In one of the largest and weirdest tech acquisitions in recent memory, Musk fought off initial opposition and a poison-pill threat to buy the social-media service. News of the deal has polarized Twitter users and employees. How will Musk tra
Trump-L'œil Oh, how the mighty have fallen. In an interview with Fox News , former president and reality TV host Donald Trump has declared to all the haters and losers that even if Twitter's new owner Elon Musk lets him back onto the site, he doesn't want to have anything to do with it. Following news that Musk has purchased Twitter for a whopping $44 billion, the ex-president told Fox that he'd
A fun thing about content moderation—the practice of social-media platforms deciding what we can and cannot say in some of the world's most important online spaces—is that almost everyone thinks that it's broken, albeit in different ways. Almost everyone also thinks that if you just put them in charge, they would fix things. When you're the world's richest man , you can actually give it a shot. A
Exclusive: Guardian learns sentience law could mean strict welfare rules extended to crustaceans and decapods Scientific experiments on crabs and lobsters could be curbed when the animal sentience bill becomes law, the Guardian has learned. There are few restrictions on how crustaceans and decapods can be treated in scientific studies, in contrast with mice and other mammals, for which there are
After news emerged that Twitter was accepting Tesla and SpaceX CEO Elon Musk's offer to buy the company, the site's now-departed founder Jack Dorsey weighed in on the acquisition. "In principle, I don't believe anyone should own or run Twitter," he wrote . "It wants to be a public good at a protocol level, not a company. Solving for the problem of it being a company however, Elon is the singular
Gauntlet To the surprise of absolutely no one, Twitter workers are apparently really pissed that the company is now cooperating with Elon Musk's plan for a takeover. According to The Washington Post , numerous Twitter employees have spoken out about how upset they are over Musk waltzing in and purchasing the site for a cool $44 billion. "The news today is so crazy I literally forgot I have COVID,

Preliminary surveys in Osuna have turned up eight burial vaults as well as staircases Workers upgrading water supplies in southern Spain have come across an "unprecedented" and well-preserved necropolis of subterranean limestone vaults where the Phoenicians who lived on the Iberian peninsula 2,500 years ago laid their dead. Archaeologists exploring the site – which was discovered amid the Roman r
Picture a philosopher, and you'll probably come up with someone old and wise, like Socrates, or avant-garde, like Simone de Beauvoir. Or maybe you'll imagine an academic, toiling in a tweed jacket. Whatever image you've got, you've likely pictured an adult. But the truth is that philosophers are more common on preschool playgrounds than college campuses. That might sound odd, since we tend to thi
Lack of exposure to adenoviruses due to Covid restrictions is most likely explanation for surge, experts say Ten children in the UK have required a liver transplant following a recent surge in severe hepatitis cases among young children, with the current total standing at 114 cases across all four UK nations. A lack of exposure to common adenoviruses due to Covid restrictions during the past two
Yacht Rock A superyacht confessional reveals the supposedly Bond Villain-esque lifestyles of the rich and the famous who own these luxury vessels. In an anonymously-penned piece for the Times of London , a purported "superyacht insider" described the exploits they claim to have witnessed and participated aboard these fancy boats — which include, allegedly and eyebrow-raisingly, using energy weapo
Ten years ago, Netflix started offering its subscribers exclusive TV shows (we all, of course, remember the hit series Lilyhammer ). An approach that at first seemed like a fad quickly yielded a handful of awards juggernauts—and then became a model for the entire TV streaming industry. For the past decade, the company has spent freely to fatten its library, eventually making hundreds of shows and
NASA is still deciding on whether to take a Russian cosmonaut along for the ride on a SpaceX Crew Dragon mission to the International Space Station later this year. During a press conference about Crew-4, this week's mission to the space station , SpaceNews editor Jeff Foust inquired if a decision had been made on whether a cosmonaut would round out the crew of five astronauts, given the tense ge
Assuming Control Hackers took control of the Instagram and Discord accounts of Bored Ape Yacht Club, currently the second most valuable NFT collection by trading volume, and got away with more than ten million dollars' worth of NFTs — yet another instance of blockchain collectors losing their at times extremely valuable assets to hackers and scams. At least 24 Bored Apes and 30 Mutant Apes have b
Judge, Jury, Executioner Machine learning researchers are teaching neural networks how to superficially judge humans — and the results are as brutal as they are familiar. A study about the judgmental AI, published in the prestigious Proceedings of the National Academy of Sciences journal , describes how researchers trained the model how to judge attributes in human faces, the way we do upon first
When Benito Mussolini founded, on March 23, 1919, the organization that would become the National Fascist Party, Italy's top newspaper relegated the news to a blurb, roughly the same space devoted to the theft of 64 cases of soap. That's where Antonio Scurati's novel M: Son of the Century starts. It ends on January 3, 1925, the date commonly considered the beginning of Mussolini's authoritarian r
This week, the Supreme Court will hear oral arguments in Oklahoma v. Castro-Huerta , a case that is seeking to limit the scope of a decision the Court made less than two years ago. In July 2020, the Supreme Court ruled in McGirt v. Oklahoma that Congress never annulled the Muscogee Nation reservation. After the McGirt ruling, an additional five reservations in the state were affirmed by lower cou
Once, long ago, the only players in the grand drama of life, predation and death were invisibly small and simple cells. Archaea and bacteria jigged and whirled through seas and ponds, assembled themselves into fortresses a few microns wide, and devoured films of organic matter. Then some of them began to change, and eventually the first eukaryote — the first organism to keep its genes locked away
The day I spoke to Jennifer Doudna was a tough day: the US Patent Office had just ruled against her university on CRISPR's most important uses, handing the commercial rights to her rivals at the Broad Institute of MIT and Harvard. Doudna is the co-discoverer of CRISPR editing, the revolutionary method for engineering genes that, 10 years after her original breakthrough, is now making its way into
A Spanish man had a roundworm infection so bad that doctors could literally see the larvae slithering under his skin . A new case study published in the New England Journal of Medicine details the 64-year-old man's rare "hyperinfection," which was officially diagnosed as a side effect from the Strongyloides stercoralis nematode's larvae. The horrific photos of the former sanitation worker's infec
Rolling in the Deep Space is for the birds — to get the next-level adrenaline-inducing experience so many rich folks seem to be pining for, private submarine companies are looking to the depths of the ocean. A Dutch company that calls itself U-Boat Worx — yes, they share a name with the infamous German submarines from World Wars one and two — is now offering the wealthy a chance to do luxury deep
When visiting cities, coyotes seem to prefer the nightlife while deer and squirrels would rather be home before dark. That's the finding of new research from University of Utah ("the U") scientists who found that mammals in urban environments shifted the timing of their daily activities, likely to avoid encountering humans.
Every EU citizen consumes around 80 kilograms of meat per year. But every juicy steak, every delicious sausage has a price that we do not pay at the counter, because livestock farming damages the climate and the environment. Ruminants, for instance, produce methane, which accelerates global warming. Animals also convert only a portion of the calories they are fed into meat. In order to feed the sa
The role of the first lady has long been ill-defined . Until recently , she was the most prominent and therefore scrutinized woman in the White House, yet her position comes with murky expectations. Modern first ladies tend to manage a staff and champion carefully chosen causes, but their duties aren't formally circumscribed. How many duties are too many? How many are not enough? Showtime's The F
In theory, coming up with a fair division of housework should be simple: Take all the tasks and divide them in two. In practice, it's more complicated. Some people find certain tasks more bearable than their partners do. Some chores are ones that no one wants to do. And, on average, women end up bearing a disproportionate share of their household's chore burden. A new study adds another variable
A research group led by Sa Kan Yoo at the RIKEN Center for Biosystems Dynamics Research (BDR) has discovered a completely unknown type of cell death that takes place in the guts of the common fruit fly. The new process, called erebosis by the researchers, is thought to play a role in gut metabolism. The findings compel a revision of the conventional concept of cell death and overturn the previousl
Last Monday, Malcolm Nance, an MSNBC talking head and former sailor in the United States Navy, showed up on the channel by satellite from Ukraine, dressed to kill. He wielded an assault rifle and wore full-camo military dress, including a ballistic helmet, and U.S. and Ukrainian flag patches. About a month ago, he said, he decided he was "done talking." He then talked about how he had joined Ukra
In the last 20 years, there have been efforts to reduce fossil fuel use in plastics manufacturing, and, according to Penn State researchers, efficient, customizable catalytic reactions—where two metals are combined using a catalyst, or molecule that remains unchanged during a reaction—are an attractive alternative.
As most archaeological material is found in a fragmented state, the phenomenon has been considered a natural consequence of objects' having been long buried underground. However, according to Postdoctoral Researcher Marja Ahola from the University of Helsinki, not all objects have necessarily been broken by accident. Instead, it is possible some were fragmented on purpose as part of maintaining so
After two years of suspensions and postponements because of the coronavirus pandemic, Carnival celebrations took place again in São Paulo and Rio de Janeiro this weekend. Thousands of spectators jammed into Sambadromes once more to watch the spectacle of samba-school floats, dancers, and extravagant costumes. Collected below are images of some of the Carnival 2022 festivities in Brazil.
Tiny beetles that feed on fruit from the palm family may have developed their taste for coconuts long ago, according to a Penn State-led team of scientists studying suspected insect damage in a 60-million-year-old fossil.
A multidisciplinary research team from the Max Planck Institute for Evolutionary Anthropology in Leipzig, the Friedrich Alexander University Erlangen-Nuremberg, the Leuphana University Lüneburg, the Leibniz Institute for Applied Geophysics and other partner institutions investigated whether Neanderthals were well adapted to life in the cold or preferred more temperate environmental conditions.

The US hosts more child sexual abuse content online than any other country in the world, new research has found. The US accounted for 30% of the global total of child sexual abuse material (CSAM) URLs at the end of March 2022, according to the Internet Watch Foundation, a UK-based organization that works to spot and take down abusive content. The US hosted 21% of global CSAM URLs at the end of 20
Potentially dangerous mutations could go unnoticed due to cuts in testing A dramatic drop in testing for Covid-19 has left the world blind to the virus's continuing rampage and its potentially dangerous mutations, the head of the World Health Organization has warned. The UN health agency said that reported Covid cases and deaths had been dropping dramatically. Continue reading…
This was the first time Nasa opened its space hatches to tourists, who paid $55m for a week, which was extended to nearly 17 days Three rich businessmen returned from the International Space Station with their astronaut escort Monday, wrapping up a pricey trip that marked Nasa's debut as a B&B host. Flying back in a SpaceX capsule, they splashed down in the Atlantic off the Florida coast to close
Using data from ESA's Gaia space observatory, astronomers from the Istanbul University in Turkey have inspected four galactic open clusters. Results of this research, available in a paper published April 16 on the arXiv pre-print repository, deliver important insights into the properties of these objects.
Abnormal Distribution The International Atomic Energy Agency (IAEA), the United Nations' atomic watchdog, is warning that radiation levels at Ukraine's Chernobyl nuclear disaster site have been rising ever since Russian forces took control over the site earlier this year. "The radiation level, I would say, is abnormal," IAEA director Rafael Grossi said during a visit to the site that marked the a
The number of coal-fired power plants in the pipeline worldwide declined in 2021, according to research released Tuesday, but the fossil fuel most responsible for global warming still generated record CO2 emissions, threatening Paris climate goals.
Just as an electrical switch regulates the flow of electric current, thermal switches can control the flow of heat. These switches serve as thermal control devices and are useful for thermal management applications. For example, they can be used in industries to reduce waste heat, resulting in cost and energy savings. These switches require materials whose thermal conductivity (κ) can be modulated
Scientists have demonstrated the effectiveness of an innovative nuclear mass measurement method using the rare-RI ring (R3) facility at the Radioactive Isotope Beam Factory, and applied it to the mass measurement of a neutron-rich palladium isotope. The study was published in Physical Review Letters on April 15.
The Gangdese porphyry copper deposit belt (GPCDB) is along the southern margin of Lhasa Terrane. The deposits of GPCDB were formed in the Miocene after the India-Eurasia collision. The genesis of these porphyry copper deposits is controversial.
The secrets hiding in the vast expanse of outer space have intrigued humankind for ages. The invention of the optical telescope during the 17th century allowed humans to see stars appearing as mere twinkling dots in the night sky. Thanks to scientific innovations over the next four centuries, we can now launch telescopes into space to get a better look at astronomical objects and even study them a
Loren Pankratz's book covers the whole spectrum of different kinds of deception. It is well written, informative, and entertaining, with case examples that read like detective stories. The post Patients Who Deceive first appeared on Science-Based Medicine .
A new study finds that the national economic burden of PTSD goes beyond direct health care expenses and exceeds the costs of other common mental health conditions, such as anxiety and depression. The researchers estimated the cost of PTSD at $232.2 billion for 2018, the latest year for which data were available at the time of the study.
Although stream restoration filters pollutants out of local waterways and improves the health of the Chesapeake Bay, Baltimore area neighborhoods where it would do the most for water quality are far less willing to pay for such projects, according to a new study by a University of Maryland environmental economist and an interdisciplinary team of colleagues.

As the news came out of China that there was a new virus infecting humans, scientists around the world promptly got to work sequencing genomes, gathering data and communicating what they found with the public. One of the scientists catapulted into the public eye was Devi Sridhar , a professor in global public health. Soon, she was advising the Scottish government on their Covid strategy, regularl
Vervet monkeys are quick and clever planners of the best route to follow on foraging trips, shows a new study. When dominant group mates are too far away to interfere, vervets tend to choose the shortest route along successive food sites, snacking on each at leisure. But when dominants group mates are nearby, they seem to assess the time before these can approach and displace them at the feeding s
Laboratory experiments find that Toxoplasma, Cryptosporidium, and Giardia can congregate on microplastic beads and fibers, suggesting they might make their way into and around the world's oceans by hitching rides on tiny bits of trash.
Doomsday The United Nations has issued yet another terrifying report about our near future — and readers, we're not in for a good time. Published every other year, the UN Global Assessment Report on Disaster Risk Reduction is tasked with outlining ways humanity can mitigate catastrophic risk. Unsurprisingly, this year's report is telling us that we're living in a hell of our own creation. The rep
People who have a critical attitude toward factory farming or who pay attention to their health in everyday life are more likely to turn to meat substitutes. Concern for the environment, on the other hand, appears to play no role in this decision.
An artificial intelligence (AI) tool can accurately predicted who would develop pancreatic cancer based on what their CT scan images looked like years prior to being diagnosed with the disease. The findings may help prevent death through early detection of one of the most challenging cancers to treat.
China's mountainous southwestern area is home to one of the country's most ethnically diverse populations. In the most comprehensive genetic analysis of the native people there to date, researchers reveal that the ethnic groups' peopling and migration history is more complex than previously concluded.
Researchers have shown that the UK's existing copper network cables can support faster internet speeds, but only to a limit. They say additional investment is urgently needed if the government is serious about its commitment to making high-speed internet available to all.
Researchers propose using a complex-network-based clustering workflow to search for synchronized structures of extreme rainfall events within the context of atmospheric chaos. By doing this, they were able to reconstruct a functional climate network to encode the underlying interaction of the climate system. Clusters on the network revealed regions of similar climatological behaviors. This means e
Mammals can't typically regenerate organs as efficiently as other vertebrates, such as fish and lizards. Now, scientists have found a way to partially reset liver cells to more youthful states — allowing them to heal damaged tissue at a faster rate than previously observed. The results reveal that the use of reprogramming molecules can improve cell growth, leading to better liver tissue regenerat
It's unusual for a one-off political speech to make someone famous. This is especially the case in today's toxic fog of disinformation and apathy. But last week a Democratic state senator named Mallory McMorrow from Royal Oak, Michigan, somehow broke through when she stood up on the floor of the Michigan Senate and defended herself against smears from another state senator, Lana Theis, who wrote
New research explores the spillover of myxoma virus from European rabbits to Iberian hares. In addition to shedding new light on species-jumping viruses, the study shows that the protein permitting the species jump from rabbits to hares may help improve myxoma as a cancer-fighting agent.
A potential game-changer in the tuberculosis epidemic was how the tuberculosis community viewed rapid molecular tests for tuberculosis and tuberculosis drug resistance. This was 12 years ago, with the launch of Xpert MTB/RIF, which gives results in less than two hours, simultaneously diagnosing tuberculosis and testing if the bacteria have rifampicin resistance, a type of drug-resistant tuberculos
Elon Musk is buying Twitter and taking the public company private in order to save "free speech." That much we know: He has made his intentions clear. But what will actually change about the social-media platform is still largely a mystery, and the hints don't suggest that Twitter's about to become a free-speech free-for-all. Maybe Musk will reinstate Donald Trump on the platform. Perhaps he'll a
The Apple Watch is a powerful, multi-purpose smartwatch, but you won't be able to take advantage of any of its features if its battery dies, which is why the best Apple Watch chargers come in handy. Apple has maintained that the Apple Watch has "all-day" battery life, which it quantifies as 18 hours. In our experience, the Apple Watch does last far longer than a smartphone, tablet, or laptop, but
Theophylline or THO is a natural organic compound whose molecular structure is very similar to that of caffeine present in coffee and cacao. Over the years, due to its therapeutic properties, THO has become one of the most widely studied xanthine group derivates. THO is used to dilate respiratory passages in people having difficulty breathing, and as a muscle relaxant, anti-asthmatic, and diuretic
If we compare the right to the left hand, we can see these are specular images—that is, like symmetrical shapes reflected in a mirror—and they cannot superimpose on each other. This property is chirality, a feature of the matter that plays with the symmetry of biological structures at different scales, from the DNA molecule to the tissues of the heart muscle.
Space urgently needs special legal protection similar to that given to land, sea, and atmosphere to protect its fragile environment, scientists argue in a new paper. The scientific, economic, and cultural benefits of space should be considered against the damaging environmental impacts an influx of space debris—roughly 60 miles above Earth's surface—pose, fueled by the rapid growth of so-called s
New research finds a "bi-directional" relationship between gastrointestinal issues and internalized symptoms in children and adolescents with autism. That means the symptoms seem to be affecting each other simultaneously. Children with autism spectrum disorder tend to experience gastrointestinal issues , such as constipation and stomach pain, at a higher rate than their neurotypical peers. Some a
The outer-core size of tropical cyclones (TCs) is vital for evaluating their destructive potential. It is usually defined as the radius of gale-force wind (R17), but accurately forecasting R17 is challenging owing to our incomplete understanding of the physical mechanism that determines it. Nonetheless, there is a general consensus that the TC outer-core size is mainly regulated by the TC's outer
The first demonstration of the laser in 1960 was rapidly followed by the birth of a new research field: nonlinear optics. The unique coherence properties of stimulated emission, the fundamental physical process of laser radiation, has enabled intensities that exceed those of incoherent sources by many orders of magnitude. The high intensities drive electrons so strongly that they oscillate with fr
Freshwater pearl mussels are found in rivers in Japan. They are in severe decline, however, and are on the endangered Red List designated by the Ministry of the Environment. Freshwater pearl mussels are known to play an important role in the biochemical ecosystem of river nutrients in the area and downstream.

How do we assess the needs of people with severe multiple disabilities? Unable to communicate verbally and physically, this population has nearly no possibility of expressing itself. Thanks to eye-tracking technology, a team has succeeded in identifying and evaluating certain perceptive and social-emotional abilities in nine children and adolescents with multiple disabilities, opening the way to p
The National Highway 715, which passes through the Kaziranga National Park in Northeast India, is notorious for its roadkill. With protected habitats on both sides of the road, many animals cross it on a daily basis to feed and breed.
Microplastics are a pathway for pathogens on land to reach the ocean, with likely consequences for human and wildlife health, according to a new study. This study connects microplastic pollution in the ocean with land-based, diseases-carrying pathogens. The study, published April 26 in the journal Scientific Reports, is the first to connect microplastics in the ocean with land-based pathogens
A study shows that the preference of biological molecules for left or right-handedness — a hallmark of living matter — could emerge spontaneously as prebiotic chemical networks adapt to optimize energy harvesting. The proposed mechanism of symmetry breaking is general and can apply to other transitions in living matter that lead to increased complexity.
A survey has found that endangered and threatened insects and spiders, as well as common species that provide valuable ecological services, can be easily purchased– without adequate oversight—through basic internet searches, according to a new Cornell study.
The world's coral reefs are becoming extinct due to many factors such as global warming and accelerated urbanization in coastal areas, which places tremendous stress on marine life. "The rapid decline of coral reefs has increased the need for exploring interdisciplinary methods for reef restoration," explains Natalie Levy, a Ph.D. student at Bar-Ilan University in Israel. "Examining how to conserv
Italian nurse Daniela Poggiali was arrested and convicted of murdering two hospital patients in 2014. Her case attracted the attention of Leiden statistician Richard Gill. After his investigation, together with an Italian colleague, Poggiali was acquitted last autumn. Together with fellow statisticians, Gill is trying to prevent this type of statistical error in the future.
A new study offers a "dismal picture" of math textbooks across the globe. The research has serious implications for the next generation of learners. Among the findings, the researchers discovered that student "opportunities to learn and develop mathematics literacy are so few as to almost be nonexistent" in eighth grade textbooks. Moreover, what is given to them in traditional word problems are l
Greenhouse gas emissions from human activities have caused Earth's climate to change—and in Arctic regions, air temperatures are warming twice as fast as the global average. Permanently frozen Arctic soils located in tundra ecosystems store approximately twice the amount of carbon currently in the atmosphere. This frozen organic matter is thawing, thus increasing microbial decomposition, which rel
Meat substitutes are on the rise: While they used to have a niche existence in health food stores or organic stores, wheat salami, tofu schnitzel or soy mince can now be found in every well-stocked supermarket. "We wanted to know why consumers choose these alternatives," explains Jeanette Klink-Lehmann, who is doing her doctorate at the Institute of Food and Resource Economics at the University of
Homeowners in Baltimore area neighborhoods where stream restoration would do the most for water quality are far less willing to pay for such projects, than those in other areas, according to a new study.
A multidisciplinary research team has investigated whether Neanderthals were well adapted to life in the cold or preferred more temperate environmental conditions. Based on investigations in Lichtenberg in the Wendland region (Lower Saxony, Germany), the researchers showed that during the last Ice Age, Neanderthals visited their northernmost settlement areas even during cold phases — albeit more
A study reports that children with ADHD and emotional dysregulation randomized to take a micronutrient formula were three times more likely to show symptomatic improvement on blinded clinician ratings, compared to those in the placebo group (54% versus 18%). The micronutrient formula, consisting of all known vitamins and essential minerals, was administered for eight weeks.
Finding out the sex of a baby during pregnancy could lead to better life chances, a new study has discovered. Male baby pregnancies are more likely to result in complications, possibly because they grow faster in the womb and require more nutrients and oxygen than supplied by the mother through the placenta — the temporary organ that attaches to the wall of the uterus during pregnancy to help the
A white humpback whale, similar in appearance to the famous Migaloo, has been spotted off the coast of New South Wales in Australia. It has been suggested that it may be related to the famous albino humpback Migaloo.
Collective behavior and swarm patterns are found everywhere in nature. Robots can also be programmed to act in swarms. Researchers have developed collectives of microrobots, which they can move in every formation they wish.
When the global community is expected to meet for the second part of the UN Biodiversity Conference in Kunming, China, in autumn, it must also adopt the next generation of UN biodiversity targets. These will then replace the Aichi Targets that were aimed for until 2020—and have hardly been achieved. Twenty-one "Post-2020 Action Targets for 2030" have already been pre-formulated. While they still h
The Drake equation is one of the most famous equations in astronomy. It has been endlessly debated since it was first posited in 1961 by Frank Drake, but so far has served as an effective baseline for discussion about how much life might be spread throughout the galaxy. However, all equations can be improved, and a team of astrobiologists and astronomers think they have found a way to improve this

Plastic is a petroleum product that is extremely slow to decompose. According to the German Nature and Biodiversity Conservation Union, a plastic bag takes 10 to 20 years, a plastic straw 200 years and a plastic bottle 450 years to decompose. During decomposition, these objects are ground into ever-smaller particles over time. These are known as microplastics (particles smaller than 5mm) or nanopl
Launched back in 2018, Aeolus has outlived its 36-month in-orbit design life—but going above and beyond, it continues to deliver excellent data. This shows that there's life yet in the satellite, meaning ESA's wind mission is now expected to continue shining a light on the wind for another year.
"Is it the road that crosses the habitat, or does the habitat cross the road?" ask scientists at Gauhati University (Assam, India) before agreeing that the wrong road at the wrong place is bound to cause various perils for the local wildlife, habitats and ecosystems. Furthermore, some of those effects may take longer than others to identify and confirm.
The SpaceX Falcon 9 rocket launches with the Double Asteroid Redirection Test, or DART, spacecraft onboard, Tuesday, Nov. 23, 2021, Pacific time (Nov. 24 Eastern time) from Space Launch Complex 4E at Vandenberg Space Force Base in California.

The latest U.N. report on climate change documented researchers' efforts that have shown some measures of global warming are now unavoidable, and current research efforts are focusing on mitigation and adaptation strategies. The National Aeronautics and Space Administration describes this as a global problem, felt on local scales. Likewise, National Oceanic and Atmospheric Administration researche
Storytelling is an ancient human trait. We were perhaps making manifest our imaginings even before we had the spoken word. In the modern world, stories are as important to us as they ever were and are crucial to many human endeavors in the creative arts, in scientific research, and, of course, in the commercial world. Work published in the International Journal of Business and Globalisation, inves
Drought and the potential increase in the number of droughts worldwide due to climate change remains a concern for scientists. A recent study led by Stony Brook University researchers suggests that human migration due to droughts will increase by at least 200 percent as we move through the 21st Century. Based on a series of both climate and social science modeling systems and other social science
They are everywhere: in riverbanks, on glaciers, in deserts, in fish populations, even in the air we breathe. And these are just a few of the places where scientists have found microplastics, plastic debris roughly the size of a sesame seed that move easily through the environment, the impact of which remains somewhat of a mystery, Northeastern University experts say.
A survey of public opinion in China conducted by researchers at Rice University, the National University of Singapore and the University of British Columbia shows the country's perceptions of the U.S. plummeted during the presidency of Donald Trump.
A combination of atmospheric measurements and fine-scale simulations has improved understanding of the modeling anomalies that arise when the model resolution approximates the length scale of turbulence features—an atmospheric simulation problem known as Terra Incognita. The research, published in Monthly Weather Review, provides valuable insight into how best to link large- and small-scale simula
Try to picture a proton—the minute, positively charged particle within an atomic nucleus—and you may imagine a familiar, textbook diagram: a bundle of billiard balls representing quarks and gluons. From the solid sphere model first proposed by John Dalton in 1803 to the quantum model put forward by Erwin Schrödinger in 1926, there is a storied timeline of physicists trying to visualize the invisib
Launcher integration for the inaugural flight of Vega-C began with the P120C solid-fuel first stage being delivered to the Vega Launch Zone (Zone de Lancement Vega, or ZLV) at Europe's Spaceport in Kourou, French Guiana on 15 April 2022. P120C will also fly on Ariane 6, with two or four units serving as boosters depending on mission requirements.

Glaciers of carbon dioxide are moving, creating deposits kilometers thick today across the south polar region of Mars, something that could have been going on more than 600,000 years, a paper by Planetary Science Institute Research Scientist Isaac Smith says.
An international team of researchers examined data for 25 exoplanets and found some links among the properties of the atmospheres, including the thermal profiles and chemical abundances in them. These findings will help establish a generalized theory of planet formation which will improve our understanding of all planets, including the Earth.
If "Jurassic Park" fueled your interest in dinosaurs, genetics, and all things ancient, you aren't alone. There's an entire field dedicated to looking for ancient DNA—molecular paleontology—that predates Michael Crichton's take on dino clones. And the people behind that research are just as varied and interesting as any of Crichton's subjects.
"It is time to close the funding gap for Black female-led start-ups the world over," says entrepreneur Temie Giwa-Tubosun, whose company LifeBank delivers life-saving medical supplies to remote areas in Africa. Today, LifeBank operates successfully across the continent, but Giwa-Tubosun knows that barriers to funding prevent many other brilliant business ideas from blossoming. She highlights examp
The COVID-19 pandemic and its public response created large shifts in how people travel. In some areas, these restrictions on travel appear to have had little effect on air pollution, and some cities have worse air quality than ever.
Semiconducting nanomaterials with 3D network structures have high surface areas and a lot of pores that make them excellent for applications involving adsorbing, separating, and sensing. However, simultaneously controlling the electrical properties and creating useful micro- and macro-scale structures, while achieving excellent functionality and end-use versatility, remains challenging.

Cancers are like malicious snowflakes. Each harbors a unique set of mutations in its genes, gradually turning them to the dark side. Eventually, with no regard for their neighbors, mutated cells destroy tissues, organs, and life. But their set of genetic mutations—a signature—can also be their downfall. Like fingerprints or DNA left at a crime scene, we can use those signatures to hunt down cance
Domestic abuse can involve one parent using a child as a weapon against the other parent, which harms the child in immense ways. My research has identified how these dynamics play out and examines the damage.
(Photo: Ashraful Islam/Unsplash) If someone could tell you how much longer you're expected to live, would you want to find out? Thanks to research conducted over the last decade, this question is no longer rhetorical. Scientists are using "aging clocks," or indicators of biological age, to figure out approximately how much life people have left. It all started when biostatisticians Steve and Mark
Climate change has caused a rapid and extensive rise in temperature in Scotland's lochs and reservoirs, according to research published on Tuesday that predicts the trend will continue if nothing is done.
To the untrained eye, the small community garden on Coast and Straits Salish territory—on what passersby commonly know as the University of Victoria campus—might look unruly. Bursting with dandelions, lamb's ear and grasses, it's difficult to tell where the garden starts and where it ends.
While microwaves are generally considered safe and efficient, new research indicates that at extremely high magnitudes of power, microwaves have the potential to cause brain injuries. Contrary to what was once popular belief, microwaves don't cause cancer. It's a decades-old concern that may evoke an image of a child standing in front of a microwave, peering through the dimly-lit door, only to be
Getting out of prison is often assumed to be cause for celebration and a new beginning. However, many women exiting prison face profound disadvantage, isolation, poor mental and physical health and struggle finding housing.
In 1928 Scottish microbiologist Alexander Fleming, while studying the staphylococcus bacteria, noticed mold on his petri dishes inhibited its growth. He experimented, leading to the discovery of penicillin, the first antibiotic.

Are we headed for a world in which most of the meat we consume was grown in a vat rather than in an animal? This is a fairly high-stakes question (pun intended). We have a growing population, we are already using most of the arable land available, and we are pushing the efficiency of agriculture. There is still some technological head room, mostly with GMO technology, to improve yields further. B
A new method uses artificial intelligence to analyze animal behavior, which could lead to longer-term in-depth studies in the field of behavioral science. In addition, the advance helps to improve animal welfare. The method is already in testing at the Zurich Zoo.

Researchers have developed a technique using sodium magnetic resonance imaging (MRI) to detect salt levels in breast cancer tumors in mice. Imaging salt levels could be a vital new tool to help diagnose and monitor breast cancer, the researchers say.
Almost everyone now is breathing polluted air, and with how air pollution is damaging the atmosphere and our own bodies, I imagine the possibility of someone creating a gadget that would lead us to directly affect the air, perhaps a sneaker that produces oxygen and/or clean air with every step you took (like how light-up LED shoes work)– if it's possible. What would be the limitations and or pro
Medical researchers explore the galaxy of viruses present in the gut, known as the gut virome. They find that some preterm infants undergo marked alterations in their pattern of gut viruses shortly before developing a serious and often fatal disease known as necrotizing enterocolitis (NEC).

New research results demonstrate how inflammation from a COVID-19 infection during pregnancy could potentially impact long-term infant health, including infant growth and brain development. A new study describes how infants of mothers who had a COVID-19 infection during pregnancy had significant elevations in inflammatory blood markers, also known as cytokines, at the time of delivery.
Microplastics are all around us—in the water we drink, the food we eat and the air we breathe. But before researchers can understand the real impact of these particles on health, they need faster and more effective ways to quantify what is there.
The US must do what it can to prevent Russian military from crossing the nuclear threshold, Scott Sagan argues. Nuclear weapons are not just a force used to deter another state from attacking, they can also be a shield behind which one can engage in aggression, says Sagan , the co-director of the Center for International Security and Cooperation at Stanford University. Sagan's research examines n
While the smartphones most of us carry in our pockets tell time without any trouble, they fail to deliver the aesthetic charm and offhand ease of the best watches.

Bees are among the most important pollinators on earth. They pollinate not only plants with beautiful flowers, but also many crops. But despite the insects' great importance for humans and nature, their population is declining. Researchers cite various possible causes for this, including pesticides. This factor has now been investigated in a study by an international research team with the partici
How do we perceive music and sounds? This question is the basis of the research by the Language and Comparative Cognition Group (LCC) of the UPF Center for Brain and Cognition (CBC) published recently in the journal Animal Cognition.
Pollination by insects is essential for the production of many food crops. The presence of pollinators, such as bees, depends on the availability of nesting sites and sufficient food. If these conditions are lacking, the pollinators also fail to appear and the yield of flowering arable crops, such as broad beans or oilseed rape, suffers as well. A team from the University of Göttingen and the Juli
Offshore wind power could help lower wholesale electricity prices on average for six states in New England, with relatively low risk of wind turbines failing during extreme winter storms, a new analysis shows. Although very high wind speeds during winter storms could cause turbines to go temporarily offline, the researchers found the largest risk of sudden losses of wind power would be in summer
In areas where water is scarce, reusing wastewater is one way to increase the supply. But to do that safely, water has to undergo lots of cleaning procedures, including some new innovations using edible materials like okra!
Clean-up operation | Trouble up north | Alveolar plosives | Ramblers' descent | Boris Johnson's lucrative future In his fascinating article on space junk, Ian Sample informs us that the radar tracking the debris in the UK is operated by the RAF ( Mind that satellite!

Among the many complex arguments over water in California, one particularly heated debate centers on whether the state should seek more drinking water from a plentiful but expensive source: the Pacific Ocean.
Temporary changes to Medicaid eligibility during the COVID-19 pandemic meant that women who were due to lose coverage 60 days after giving birth were able to stay on their plans, researchers report. It's been the case for decades: high numbers of US women who give birth lose or face changes to their health insurance afterward. And those with Medicaid benefits are most likely to lose coverage, bec
Plants have been the primary source of our food for ages. With the human population growing rapidly, there is a continual increase in the demand for food produce. Since agricultural land is limited, fulfilling this increasing demand requires finding ways to improve the food crop productivity from existing cultivations. "Crop architecture," or the design of the crop plant, can have a major influenc
The Karnali River is one of the major transboundary rivers of the Nepalese central Himalaya and a major tributary of the Ganges River. Though there is a huge potential for dendrohydrological research in the Karnali River Basin (KRB) region in Nepal, no multi-centuries streamflow reconstruction is available yet.
Remnant trees play an important role for post-disturbance forest landscape recovery. Due to the nucleation of remnant trees in forest recovery, their spatial configuration, e.g., location and abundance, is a critical factor driving forest landscape recovery.

A new way of using artificial intelligence to predict cancer from patient data without putting personal information at risk has been developed. Swarm learning can be used to help computers predict cancer in medical images of patient tissue samples, without releasing the data from hospitals.
It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes — the biological catalysts in all living organisms — form or break chemical bonds.
Nature, Published online: 25 April 2022; doi:10.1038/d41586-022-01157-5 A study of university review and promotion documents suggests that collaboration and teamwork are widely considered, but not consistently assessed.
A new hypothesis reveals that a global sedimentary cycle driven by seasons could explain the formation of landscapes on Saturn's moon Titan. The research shows the alien world may be more Earth-like than previously thought.
Post-starburst galaxies were previously thought to scatter all of their gas and dust — the fuel required for creating new stars — in violent bursts of energy, and with extraordinary speed. Now, new data from the Atacama Large Millimeter/submillimeter Array (ALMA) reveals that these galaxies don't scatter all of their star-forming fuel after all. Instead, after their supposed end, these dormant g
In an analysis of the most recent data available through the CDC, clinical researchers revealed that firearm injuries are now the leading cause of death among children up to age 19, and the racial gap between black and white youth is widening. The article calls for health care workers to recognize this as an epidemiological and public health challenge and to help find solutions.
BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.
Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.
Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
