A research team from Osnabrück University and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has, for the first time, observed lethal attacks by chimpanzees on gorillas in the wild. Whether this behavior is due to competition for food or to the decline of the rainforest's productivity caused by climate change will now be investigated in more detail.
It was like listening to a family riding a thrill ride together at a theme park. But it was actually a billionaire and a few of his pals screaming as Blue Origin successfully completed its first crewed mission to the edge of space. The company's New Shepard spacecraft RSS First Step rocketed from the West Texas desert high into the Earth's upper atmosphere, reaching an apogee of 351,210 feet, or
Little evidence that social restrictions during the pandemic have added to rates of death and ill-health Coronavirus – latest updates See all our coronavirus coverage Since early in the coronavirus pandemic, critics of unprecedented lockdown measures seen worldwide have argued that these interventions cause more harm than the disease itself. But an analysis of global health data suggests there is
Using ART-XC and eROSITA telescopes onboard the Spectrum Roentgen Gamma (SRG) mission, an international team of astronomers has detected a new pulsar. The newly found object, designated SRGA J204318.2+443815, turns out to be a long-period, faint X-ray pulsar in a distant binary system. The finding is reported in a paper published July 12 on arXiv.org.
One of the topics investigated in recent physics studies is strong-field quantum electrodynamics (SF-QED). So far, this area has rarely been explored before, mainly because the experimental observation of SF-QED processes would require extremely high light intensities (>1025W/cm2), over three orders of magnitude higher than those attained using the most intense PetaWatt (PW)-class lasers available
Analysis of children and young people's proximity to woodlands has shown links with better cognitive development and a lower risk of emotional and behavioral problems, in research led by UCL and Imperial College London scientists that could influence planning decisions in urban areas.
NASA's Hubble Space Telescope is back in business, exploring the universe near and far. The science instruments have returned to full operation, following recovery from a computer anomaly that suspended the telescope's observations for more than a month.
A team of solar physicists led by Laurent Gizon of the Max Planck Institute for Solar System Research (MPS) and the University of Göttingen in Germany has reported the discovery of global oscillations of the Sun with very long periods, comparable to the 27-day solar rotation period. The oscillations manifest themselves at the solar surface as swirling motions with speeds on the order of 5 kilomete
A recent study in Frontiers in Sustainable Food Systems shows that the fruits of a type of tomato plant send electrical signals to the rest of the plant when they are infested by caterpillars. Plants have a multitude of chemical and hormonal signaling pathways, which are generally transmitted through the sap (the nutrient-rich water that moves through the plant). In the case of fruits, nutrients f
Changes in the distribution and abundance of invasive species can have far-reaching ecological consequences. Programs to control invaders are common but gauging the effectiveness of such programs using carefully controlled, large-scale field experiments is rare, especially at higher trophic levels. Experimental manipulations coupled with long-term demographic monitoring can reveal the…
Global warming drives changes in Earth's cloud cover, which, in turn, may amplify or dampen climate change. This "cloud feedback" is the single most important cause of uncertainty in Equilibrium Climate Sensitivity (ECS)—the equilibrium global warming following a doubling of atmospheric carbon dioxide. Using data from Earth observations and climate…
While the important role of animal-mediated interactions in the top-down restructuring of plant communities is well documented, less is known of their ensuing repercussions at higher trophic levels. We demonstrate how typically decoupled ecological interactions may become intertwined such that the impact of an insect pest on forest structure and…

In early July, The New York Times published two articles that had seemingly little to do with one another. One covered the Entomological Society of America's decision to stop using the terms gypsy moth and gypsy ant . The other was about a new movie by the director Paul Verhoeven featuring an affair between two 17th-century nuns. "Forgive them, Father, for they have sinned," the article begins. "
Rocketing Emissions The billionaire space race is well on its way , setting the stage for a burgeoning space tourism industry. More civilian space tourists are making their way into space than ever before — a trend likely to grow substantially as the sector advances. At the same time, widespread rocket launches also appear to come with a considerable cost to the environment, The Guardian reports
Two-Child Policy The government of the extremely densely-populated Indian state Uttar Pradesh may soon implement new policies meant to combat overpopulation by limiting how big families in the area can get. Newly proposed policies include cash incentives for parents who only have one child, as well as free healthcare and education. But on the other hand, new punishments for larger families would
Updated at 10:53 a.m. ET on July 20, 2021. VAN HORN, Texas—This morning, the richest person on Earth boarded a reusable rocket he dreamed up and funded, launched to the edge of space to experience a few minutes of weightlessness, and then came back down. Jeff Bezos made the trip with three people who decided they trusted him enough with their lives: his brother, Mark Bezos; Wally Funk, a storied
Funk Flight Spurned astronaut Wally Funk just made it to the edge of space on board Blue Origin's New Shepard spacecraft RSS First Step. The small rocket launched from the West Texas desert, just after 9 am Eastern time. At 82-years-young, Funk has become the oldest person to travel to space — or at least past the Kármán line at 62 miles, the arbitrary boundary between the Earth's atmosphere and
Oops, Nevermind Wikipedia cofounder Larry Sanger recently shared some harsh words about his own creation. Much like every teacher you've ever had , Sanger warned in an interview with Lockdown TV that Wikipedia cannot be relied upon as a reliable source of the truth. Though he seemed to defend the original vision of Wikipedia as an accessible "open-source" project, Sanger said that Wikipedia, as i
Moonspotting It's a big month for space: Jeff Bezos and Richard Branson both almost made it there , but more importantly we can announce the discovery of yet another moon orbiting Jupiter. Jupiter already has dozens of moons — at least 80, with more being discovered all the time, Space.com notes . But even though it's just another small space rock in the crowd, the new moon S/2003J24 stands out f
D'ohniverse According to new astrophysics research, our universe may not be expanding outward in all directions. Instead, it may be rolled around itself like a gigantic cosmic donut. A team of European scientists argue in preliminary research that the folded universe — the edges of which connected in multiple places to form a closed loop — may make more sense than the endless expanse that we typi
We take for granted that an event in one part of the world cannot instantly affect what happens far away. This principle, which physicists call locality, was long regarded as a bedrock assumption about the laws of physics. So when Albert Einstein and two colleagues showed in 1935 that quantum mechanics permits "spooky action at a distance," as Einstein put it, this feature of the theory seemed…
He and his fellow space-obsessed billionaires are exactly like the rich men aboard the Titanic who pushed others aside to jump into lifeboats Jeff Bezos is the most reptilian of billionaires. His heart has never shown evidence of a drop of warm blood. Despite all of the public relations that money can buy, his discomfort with normal human emotion shines through every time he is forced to contort
Hawkocalypse Now Throughout Oregon and California, a grim phenomenon is taking hold: baby birds are trying to flee the intense heat by hopping out of their nests before they're old enough to fly, plummeting to the ground below at rates that have conservationists extremely alarmed. The problem is particularly common among the various hawks in the region, according to The Washington Post . Wildlife
Along with three other passengers, Blue Origin CEO Jeff Bezos rocketed high into the upper atmosphere on what the company is calling its first crewed mission to space. The company's New Shepard rocket, dubbed the RSS First Step, launched from the West Texas desert and reached three Gs and a blistering speed of 2,233 mph during the trip. "It's actually a pleasurable experience," Bezos said during

He's banned from Twitter and Facebook, yet Donald Trump continues to be the dominant figure in Republican—and American—politics. Multiple times per day, his super PAC blasts out his pouty statements, a range of dictations that can be trivial or seemingly end a prospective GOP primary campaign. According to White House aides I've spoken with, the strategy from President Joe Biden on down remains t
Space-obsessed billionaires come under fire with the Amazon founder declaring the critics 'largely right' As Jeff Bezos blasts into space on Tuesday, his voyage has some people asking whether the billionaire's time, or at least money, might be better spent here on earth. Bezos, the Amazon founder who has an estimated net worth of $206bn , is taking off from Texas on Tuesday morning on the rocket
Full Self-Driving Subscription Tesla has officially launched a subscription for its "Full Self-Driving" (FSD) software suite — and it's not cheap. The add-on feature allows Teslas to change lanes, navigate complex traffic intersections, and be summoned from a distance. Previously, the feature could only be enabled for a one-time fee of $10,000. Now, Tesla is offering the same package for a cool $

Feral Hogs All memes aside, feral hogs around the world are causing a huge problem for the environment, and experts aren't sure what to do about it. Animals, tools, or anything else rooting through soil tends to release sequestered carbon into the atmosphere. That's a natural part of the carbon cycle, but feral hogs are releasing boatloads of greenhouse gases as they invade and rampage through ne
According to epidemiologists, meeting outside helps minimise infection risks but heat itself has a negligible effect on the virus Coronavirus – latest updates See all our coronavirus coverage With the recent rising temperatures and more people now mixing outdoors as restrictions have been lifted in England, and eased in Scotland, Wales and Northern Ireland, experts explain how much of an impact t
America's vaccination rates have fallen off a cliff, and nothing seems to help. On June 2, President Joe Biden announced a frantic plan to reverse what already seemed to be an awful, exponential slide: At the peak of the country's vaccine rollout, in mid-April, almost 3.5 million doses were being put into arms every single day, but that number had quickly dropped by half , and then by half again.
I n the conservative world, the idea that white people in the United States are under siege has become doctrine. In recent weeks, three prominent figures have each offered their own versions of this tenet. In June, Brian Kilmeade, one of the hosts of Fox & Friends , claimed that activists were "trying to take down white culture." Also in June, Tucker Carlson, speaking on his nightly show with an
Statistician says PM's initial excuse for not self-isolating is part of pattern of pilot studies that lack transparency Coronavirus – latest updates See all our coronavirus coverage A scientist has cast doubt on the validity of a workplace pilot scheme used by Boris Johnson and Rishi Sunak to initially avoid self-isolation, accusing the government of secrecy surrounding it and other research.

With Bezos's b
Crypto by Night The computational muscle of electric cars is rising exponentially. Self-driving cars require some beefy specs to make sense of the world around them and ensure their riders' safety. That's why several companies are now marketing vehicles not just based on how many miles they can cover on a single charge, but good they are at number crunching as well. For instance, Aldo Baoicchi, t
The development of an ultrathin magnet that operates at room temperature could lead to new applications in computing and electronics—such as high-density, compact spintronic memory devices—and new tools for the study of quantum physics.
Over the weekend, a consortium of international news outlets published their findings from an investigation into the use of Pegasus, the marquee spyware product of the secretive billion-dollar Israeli surveillance company NSO Group. The reports from the Guardian , the Washington Post , and 15 other media organizations are based on a leak of tens of thousands of phone numbers that appear to have b
A serendipitous flythrough of the tail of a disintegrated comet has offered scientists a unique opportunity to study these remarkable structures, in new research presented today at the National Astronomy Meeting 2021.
This time, there was a blastoff. Blue Origin founder Jeff Bezos and three other civilians watched the sky turn from blue to black this morning as the company's reusable rocket and capsule system New Shepard passed the Kármán line, the boundary between Earth's atmosphere and outer space. Around 9:25 a.m. US Eastern time, Bezos and his fellow passengers landed safely, successfully completing the co
The release of Black Widow earlier this month was one of the biggest tests of a new Hollywood paradigm that emerged after the coronavirus pandemic began: the simultaneous rollout of a blockbuster in theaters and on streaming services. The latest Marvel movie opened in thousands of cinemas in the U.S. and Canada on the same day it was made available to Disney+ subscribers for a $30 surcharge. At f
Unlike early human species, chimpanzees do not seem to be able to spontaneously make and use sharp stone tools, even when they have all the materials and incentive to do so. That was the finding of a study of a total of eleven chimpanzees at a zoo in Kristiansand, Norway, and Chimfunshi Wildlife Orphanage, a sanctuary in Zambia. The study was conducted by Dr. Elisa Bandini and Dr. Alba Motes-Rodri
As a young boy, Denis Vandervelde realized he faced two major obstacles to achieving distinction in the study of stamps, called philately: he was penniless, and, worse, color-blind. "A lot of the expertise in stamp collecting depends on shades and tiny variations in printings," he told us. "So it was a daft hobby for me to have." Instead, Vandervelde began collecting postmarks and quickly found h
In 1930, Clyde Tombaugh , a 25-year-old amateur astronomer, spied a small, dim object in the night sky. He'd been working at the Lowell Observatory in Flagstaff, Arizona, for about a year when he used a blink comparator—a special kind of microscope that can examine and compare images—to glimpse what was for a time considered to be the ninth planet in our solar system: Pluto. By all accounts, Plut
Re-emerging from lockdown can feel fraught with danger, especially for people with a history of anxiety I recently took my first flight since the pandemic began. As I arrived at the airport, I prepared for a scene of utter carnage: people everywhere, all of them insisting on breathing; virulent microbes reveling in a field of unsuspecting targets. As someone with a history of anxiety, I took a de
Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date.
Days after Richard Branson flew to space and back , Jeff Bezos is preparing for his turn. The dueling space billionaires share a lifelong fascination with space travel and aspire to sell customers a few glorious minutes of weightlessness, high above Earth. But on one very basic point they disagree: Where does space begin? Bezos's Blue Origin is designed to take passengers to a higher altitude tha
New research has found marine seismic surveys used in oil and gas exploration are not impacting the abundance or behavior of commercially valuable fishes in the tropical shelf environment in north-western Australia.
Throughout history, people of different cultures and stages of evolution have found ways to adapt, with varying success, to the gradual warming of the environment they live in. But can the past inform the future, now that climate change is happening faster than ever before?
Burn It Down Last Friday, three autonomous worker robots set fire to their warehouse when they crashed into each other and combusted. The unfortunate glitch — or perhaps the first whispers of a robot uprising — threw everything out of whack at the London warehouse of the UK grocery giant Ocado, Insider reports . The company uses its robotic warehouse to prepare and send out around 150,000 grocer
The 108th edition of the Tour de France cycling race finished in Paris yesterday, won by Tadej Pogačar of UAE Team Emirates, after 23 teams of riders raced 2,122 miles (3,415 km) in 21 stages from June 26 to July 18. Placing second and third were Jonas Vingegaard of Team Jumbo-Visma, and Richard Carapaz of Ineos Grenadiers. Collected below are images from this year's competition.
When it was discovered in the 1980s in Argentina, this hadrosaur was diagnosed with a fractured foot. However, a new analysis now shows that this ornithopod commonly known as the duck-billed dinosaur actually had a tumor some 70 million years ago, as well as two painful fractures in the vertebrae of its tail, despite which, it managed to survive for some time.
A veterinarian in China died in May after he was infected by an extremely rare disease, called the Monkey B virus, marking the first documented case in the country's history. The Monkey B virus, also known as herpes B, almost never jumps to humans. But when it does, The Washington Post reports , cases tend to result in death. About 80 percent of untreated patients will die from complications from
As Europe seeks to reduce its reliance on China for the rare earth metals needed for modern batteries and electronics, French researchers have found a potentially potent ally: bacteria that can help extract the elements from mine slag heaps.
US cities are working to shore up their flood defenses in the face of climate change, building and upgrading pumps, storm drains, and other infrastructure. In many cases, their existing systems are aging and built for the climate of the past. And even upgrades can do only so much to mitigate the intense flooding that's becoming more common, leaving cities to come up with other solutions. Floods h
Scientists from the University of Aberdeen School of Biological Sciences and the Chinese Academy of Sciences have completed a 13-year long investigation into the survival strategies of an enigmatic small mammal, the plateau pika, that lives on the Qinghai-Tibetan plateau in China.

It was following the same trend as the stock market, which also fell on Monday, with share
What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients—nitrogen, phosphorus, or iron—to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. And the stakes are high: Marine microbial communities drive many of the elemental cycles that sustain all life on Earth.
A study in Icelandic government offices again shows the benefits of a shorter workweek. Productivity rose enough to ensure that all services were still provided as needed. Because of the study's success, 86 percent of Icelanders now or soon will have the right to a shorter workweek. In 1886, the standard workweek in the United States consisted of six, ten-hour days. On May 4th of that year, a rio
Different groups of hominins probably learned from one another much earlier than was previously thought, and that knowledge was also distributed much further. A study by archaeologists at Leiden University on the use of fire shows that 400,000 years ago knowledge and skills must already have been exchanged via social networks. The discovery was published in PNAS on 19 July.
Japan chose to ignore many warnings from doctors and went ahead with the Tokyo Olympics. Now, organizers are reaping what they sowed. The total tally of confirmed COVID-19 cases among athletes and staff has already spiked up to 71, the Associated Press reports — and that's four days before the opening ceremony. That figure also includes 31 people from the tens of thousands of international visito
Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state of the art simulations to back up results from a large sky survey, the researchers resolve a 20-year long debate on the formation of stars. Joanna Piotrowska, a Ph.D. student at the University of Cambridge, will present the new work today at the v
On 23 July 2012, humanity escaped technological and economic disaster. A diffuse cloud of magnetized plasma in the shape of a slinky toy tens of thousands of kilometers across was hurled from the Sun at a speed of hundreds of kilometers per second.
Representatives of numerous pathogenic fungal species are finding new habitat on microplastic particles in the soil and could thus be one of the possible causes of an increase in fungal infections. Researchers from Bayreuth, Hannover and Munich demonstrated this in a new study. Using high-throughput methods, the scientists analyzed fungal communities from soil samples taken from sites near human s
The Guardian's global environment editor, Jonathan Watts, speaks to Shivani Dave about extreme weather events – including the extreme heat recently recorded in the US and Canada.

Researchers have discovered another functional autoantibody in COVID-19 patients that contributes to the disease's development and the 'firestorm' of blood clots and inflammation it induces. The autoantibody makes it much harder for the body to degrade neutrophil extracellular traps, the toxic webs of DNA and proteins produced by overactive immune cells at heightened levels in COVID patients.
NASA's Mars 2020 Perseverance rover has begun its search for signs of ancient life on the Red Planet. Flexing its 7-foot (2-meter) mechanical arm, the rover is testing the sensitive detectors it carries, capturing their first science readings.

Roughly one in seven New York City children suffer confirmed mistreatment at home and many are placed in foster care. But relatively few children are permanently separated from their parents by the termination of parental rights, according to new research from Duke University and Rutgers University-Newark.
Natural substances are biologically active components produced by organisms. So far, they have been of interest to researchers primarily as the basis for medicines, because some natural substances have been shown to inhibit tumor growth or have antiviral or antibacterial effects. Natural substances are also produced by organisms in order to better cope with their environment. For example, some lic
With humanity facing an unprecedented climate crisis, the conservation of tropical forests has never been so important – their vast terrestrial carbon stocks can be turned into emissions by climatic and human disturbances. However, the duration of these effects is poorly understood, and it is unclear whether impacts are amplified…
Research from Cornell University has revealed a new form of bargaining power among Chinese platform-based food delivery workers, who conduct invisible mini-strikes by logging out of apps and airing grievances over WeChat.
Stock market bubbles, or asset bubbles, refer to a situation where stocks are valued far above what they're fundamentally worth. Unique factors contribute to each stock market bubble, but all play out in a generally similar series of stages. Research on the human social brain network offers insight into why investors participate in asset bubbles. In retrospect, there were clear signs that the sto
The in-house development of a novel SARS-CoV-2 test, creation of the Molecular Diagnostics Lab at the Fralin Biomedical Research Institute, and their importance to public health are chronicled in a new article in Nature Communications.
Scientists from the IKBFU with colleagues obtained calcium chelidonate via a semisynthesis. This substance accelerates the transformation of stem cells into osteoblasts – its use is promising as a treatment for bone diseases. A plant, Saussurea controversa, used in medicine since ancient times, served as a source for synthesis.
Despite a sharp reduction in out-of-pocket (OOP) costs for preventive care since the Affordable Care Act was enacted in 2010, patients are still receiving unexpected bills for preventive services that should be free, according to a new study co-authored by a Boston University School of Public Health (BUSPH) researcher.
The remains of microscopic plankton blooms in near-shore ocean environments slowly sink to the seafloor, setting off processes that forever alter an important record of Earth's history, according to research from geoscientists, including David Fike at Washington University in St. Louis.
Mayo Clinic researchers have found that acute kidney injury associated with COVID-19 resembles sepsis-caused kidney injury, and the immune response triggered by the infection plays a pivotal role.The findings, published in Mayo Clinic Proceedings, also suggest that mitochondrial dysfunction — a loss of function in cellular energy production — is commonly found in kidney injury related to COVID-1
A peer-reviewed study by the Environmental Working Group recommends stringent health-based exposure standards for both children and adults for radiofrequency radiation emitted from wireless devices. EWG's children's guideline is the first of its kind and fills a gap left by federal regulators.
In a new study, researchers found that a certain protein prevented regulatory T cells (Tregs) from effectively doing their job in controlling the damaging effects of inflammation in a model of multiple sclerosis (MS), a devastating autoimmune disease of the nervous system.
Every spring, the Daylight Saving Time shift robs people of an hour of sleep – and a new study shows that DNA plays a role in how much the time change affects individuals. People whose genetic profile makes them more likely to be 'early birds' can adjust to the time change in a few days. But those who tend to be 'night owls' could take more than a week to get back on track.
The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. Researchers achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which they alternately placed on top of one another. These findings could significantly increase the efficiency of solar cells
New findings from zoologists working with birds in Southeast Asia are shining fresh light on the connections between animal behaviour, geology, and evolution – underlining that species can diversify surprisingly quickly under certain conditions. Sulawesi Babblers (Pellorneum celebense), shy birds that live in the undergrowth on Indonesian islands, have begun to diverge quite significantly despite

The American carbon tax, an alluringly simple policy once hailed by environmentalists, scholars, and politicians as a cure-all for climate change that, for all its elegance in economic models, could not overcome its enduring unpopularity with the American public, died last month at its home in Washington, D.C. It was 47. The death was confirmed by President Joe Biden's utter lack of interest in p
Ecologists in a vast region of wetlands and forest in remote Oregon have spent the past decade thinning young trees and using planned fires to try to restore the thick stands of ponderosa to a less fire-prone state.
In a new study, Fralin Biomedical Research Institute at VTC scientists discovered that the alphaCT1 molecule may help repair the skin's collagen matrix by altering how scar-forming cells behave. The findings were published in the Federation of American Societies for Experimental Biology Journal.
In the Alpine foothills, in low mountain ranges, or on the seacoast, expansion of wind energy use often meets popular resistance. Researchers have now studied what this means for the energy transition.
Researchers want sexual assault survivors to know that it's normal to feel awful right after the assault, but that many will feel better within three months. They created a timeline for recovery based on meta-analysis.
For children with Type 1 diabetes, the risk of experiencing a severe hypoglycemic episode is especially common—and for parents, the threat of that happening in the middle of the night is especially frightening. Sudden and critical drops in blood sugar can go undetected overnight when the child is asleep, resulting in coma and death—an event known as "dead in bed syndrome."
A new study of COVID-19 shutdowns in the United States reveals pronounced disparities in air pollution—with disenfranchised, minority neighborhoods still experiencing more exposure to a harmful air pollutant compared to wealthier, white communities. This first-of-a-kind study published today by researchers at the George Washington University looks at how air pollution changed after schools and bus
Exactly 300 years ago, in 1721, Benjamin Franklin and his fellow American colonists faced a deadly smallpox outbreak . Their varying responses constitute an eerily prescient object lesson for today's world, similarly devastated by a virus and divided over vaccination three centuries later. As a microbiologist and a Franklin scholar , we see some parallels between then and now that could help gove
Ten years after one of the largest nuclear accidents in history spewed radioactive contamination over the landscape in Fukushima, Japan, a University of Georgia study has shown that radioactive contamination in the Fukushima Exclusion Zone can be measured through its resident snakes.
Blue Origin has successfully launched humans into space today on its New Shepard rocket. Wally Funk, Mark Bezos, Jeff Bezos, and Oliver Daemen all traveled above the 100km boundary that marks the internationally accepted von Karman line, the point at which the atmosphere of Earth is said to give way to space. Richard Branson's flight a few days ago reached 85km above sea level, which is high enou
A new study using high-speed cameras and analytical modeling offers clues on how different kinds of bubbles form and eventually pop. The oil industry, pharmaceutical companies, and bioreactor manufacturers all face one common enemy: bubbles. Bubbles can form during the manufacturing or transport of various liquids, and their formation and rupture can cause significant issues in product quality. S
Despite the best efforts of industry to work towards sustainability, most plastics (or polymers) are still made using non-renewable fossil fuels. However, researchers have now found an economical method for producing biobased acrylate resins. The study shows how all the synthesis steps, from initial building blocks right up to polymerization, can be carried out in a single reactor (one pot), minim
When it comes to craft beer, the flavor doesn't have to be all in the hops. As a panel of amateur beer tasters at Washington State University recently demonstrated, malted barley, the number one ingredient in beer besides water, can have a range of desirable flavors too.
Scientists employed a mathematical model to simulate the differentiation of epithelial cells based on signaling molecules from the liver's portal vein. This work may lead to new tools to better understand the very complicated signaling pathways involved in cell differentiation.
Researchers have found that immunoglobulin A (IgA) deficiency leads to disruption of the ileal gut microbiota and increased inflammation in the ileum in mice. This suggests that IgA plays an important role in mucosal homeostasis by regulating the intestinal microbiota and protecting against mucosal inflammation, especially in the ileum
Cellular competition is a crucial quality control process that ensures that the development of an organism relies on healthy cells.

More than half a year has passed since the first vaccine for COVID-19 and almost half the US has protection against the SARS-CoV-2 virus. But there still isn't one for children younger than 12. Vaccine makers have been working to make their products available to younger patients, launching clinical trials to evaluate whether the vaccines can safely and effectively protect children as young as 6 m
Since its outbreak in December 2019, the novel coronavirus 2019 (COVID-19) has spread to 191 countries and caused millions of deaths. Many countries have experienced multiple epidemic waves and faced containment pressures from both domestic and international transmission. In this study, we conduct a multiscale geographic analysis of the spread…
Niespolo et al. (1) report 230Th/238U "burial ages" for ostrich eggshell fragments from a 3.8-m-thick Middle Stone Age (MSA) sequence at Ysterfontein 1 shelter, west coast of South Africa (2). The ages are in expected stratigraphic order and imply that the entire 3.8-m sequence accumulated in as little as 2,300…
Klein (1) challenges two interpretations in Niespolo et al. (2). Regarding his first point, we maintain that Ysterfontein 1 (YFT1) does provide the oldest known example of full coastal adaptation as indicated by the presence of shell middens (cf. ref. 3). Klein inaccurately characterizes the age of the deepest shell…
Hybrids account for nearly all commercially planted varieties of maize and many other crop plants because crosses between inbred lines of these species produce first-generation [F1] offspring that greatly outperform their parents. The mechanisms underlying this phenomenon, called heterosis or hybrid vigor, are not well understood despite over a century…
The unequal spatial distribution of ambient nitrogen dioxide (NO2), an air pollutant related to traffic, leads to higher exposure for minority and low socioeconomic status communities. We exploit the unprecedented drop in urban activity during the COVID-19 pandemic and use high-resolution, remotely sensed NO2 observations to investigate disparities in NO2…
Sensitivity to satiety constitutes a basic requirement for neuronal coding of subjective reward value. Satiety from natural ongoing consumption affects reward functions in learning and approach behavior. More specifically, satiety reduces the subjective economic value of individual rewards during choice between options that typically contain multiple reward components. The unconfounded…
The glucocorticoid receptor (GR) is a ligand-regulated transcription factor (TF) that controls the tissue- and gene-specific transactivation and transrepression of thousands of target genes. Distinct GR DNA-binding sequences with activating or repressive activities have been identified, but how they modulate transcription in opposite ways is not known. We show that…
Neoantigen-specific T cells are strongly implicated as being critical for effective immune checkpoint blockade treatment (ICB) (e.g., anti–PD-1 and anti–CTLA-4) and are being targeted for vaccination-based therapies. However, ICB treatments show uneven responses between patients, and neoantigen vaccination efficiency has yet to be established. Here, we characterize neoantigen-specific CD8+ T…
Organoheterotrophs are the dominant bacteria in most soils worldwide. While many of these bacteria can subsist on atmospheric hydrogen (H2), levels of this gas are generally insufficient to sustain hydrogenotrophic growth. In contrast, bacteria residing within soil-derived termite mounds are exposed to high fluxes of H2 due to fermentative production…
Cytoskeletal active nematics exhibit striking nonequilibrium dynamics that are powered by energy-consuming molecular motors. To gain insight into the structure and mechanics of these materials, we design programmable clusters in which kinesin motors are linked by a double-stranded DNA linker. The efficiency by which DNA-based clusters power active nematics depends…
Grain boundary formation during coarsening of nanoporous gold (NPG) is investigated wherein a nanocrystalline structure can form by particles detaching and reattaching to the structure. MicroLaue and electron backscatter diffraction measurements demonstrate that an in-grain orientation spread develops as NPG is coarsened. The volume fraction of the NPG sample is…
Dysfunction in T cells limits the efficacy of cancer immunotherapy. We profiled the epigenome, transcriptome, and enhancer connectome of exhaustion-prone GD2-targeting HA-28z chimeric antigen receptor (CAR) T cells and control CD19-targeting CAR T cells, which present less exhaustion-inducing tonic signaling, at multiple points during their ex vivo expansion. We found…

Using electron microscopy and high-speed atomic force microscopy, researchers show the internal molecular motor behind the gliding mechanism for Mycoplasma mobile to consist of two ATP synthase-like molecules. Sharing a similar structure with ATP synthase suggests a common evolutionary ancestor. This synthase-like ATPase is challenging the origin of cells and proteins themselves.
By uprooting carbon trapped in soil, wild pigs are releasing around 4.9 million metric tonnes of carbon dioxide annually across the globe, the equivalent of 1.1 million cars, according to new research.
Highly reactive molecules cannot survive for long in nature. If researchers want to study them more closely, they must produce them under very specific laboratory conditions. Compared to "normal" molecules, many of these tiny particles have a distinguishing feature: They simply bind with everything around them and are therefore very difficult to direct.
New research found that social influencers are unlikely to change a person's behavior by example. To stimulate a shift in people's thinking, target small groups of people in the outer edge or fringe of a network.
An internal transporter that enables us to use the copper we consume in foods like shellfish and nuts to enable a host of vital body functions also has the essential role of protecting the receptor that enables us to grow new blood vessels when ours become diseased, scientists report.
Forensics specialists can use a commercial assay targeting mitochondrial DNA to accurately discriminate between wolf, coyote and dog species, according to a new study from North Carolina State University. The genetic information can be obtained from smaller or more degraded samples, and could aid authorities in prosecuting hunting jurisdiction violations and preserving protected species.
When SARS-CoV-2 infects a cell, it introduces its RNA into it and re-programs it in such a way that the cell first produces viral proteins and then whole viral particles. In the search for active substances against SARS-CoV-2, researchers have so far mostly concentrated on the viral proteins and on blocking them, since this promises to prevent, or at least slow down, replication. But attacking the
Highly reactive molecules cannot survive for long in nature. If researchers want to study them more closely, they therefore have to be produced under very specific laboratory conditions. Compared to "normal" molecules, many of these tiny particles have a distinguishing feature: they simply bind with everything around them and are therefore very difficult to direct.
Top U.S. health agencies retain the trust of the vast majority of the American public, as does Dr. Anthony Fauci, according to a new survey from the Annenberg Public Policy Center. Public confidence has grown in the safety and effectiveness of vaccines to prevent Covid-19. But people who say they rely on conservative media have less confidence in Fauci and are more likely to accept misinformation
Distance from the hospital ups the odds of a young adult or adolescent receiving a late-stage cancer diagnosis, research finds. Those living in rural versus metropolitan counties, and those living farther from the hospital where they received their cancer diagnosis, are more likely to find out at a later cancer stage, when it's generally less treatable and survival rates are lower, the study find
The high monetary cost and environmental toll of disposable N95 masks could be dramatically cut by adopting reusable masks, according to a new study that calculated the financial and environmental cost of several different mask usage scenarios.
Changing the Weather The largest wildfire in the US so far this season is so massive that it's causing mayhem with the weather itself, The New York Times reports . The Bootleg Fire in Southern Oregon has already burned 530 square miles of forest and grasslands over the last two weeks, spurred by heat waves linked to climate change — a bad omen, in other words, of what's still in store for us. "Th

Researchers compared data for pregnant women in two cities who were infected by zika virus in 2015-16. Factors that influenced the risk of fetal malformation were the high zika attack rate in the area and being infected in the first trimester of pregnancy.
New research adds to a body of evidence indicating decisions about withdrawing life-sustaining treatment for patients with moderate-to-severe traumatic brain injury (TBI) should not be made in the early days following injury.
A team of solar physicists has reported the discovery of global oscillations of the Sun with very long periods, comparable to the 27-day solar rotation period. The oscillations manifest themselves at the solar surface as swirling motions with speeds on the order of 5 kilometers per hour.
Diagnosing a rare medical condition is difficult. Identifying a treatment for it can take years of trial and error. In a serendipitous intersection of research expertise, an ill patient in this case a child and innovative technology, Bachmann-Bupp Syndrome has gone from a list of symptoms to a successful treatment in just 16 months.
Every spring, the Daylight Saving Time shift robs people of an hour of sleep – and a new study shows that DNA plays a role in how much the time change affects individuals. People whose genetic profile makes them more likely to be "early birds" can adjust to the time change in a few days. But those who tend to be "night owls" could take more than a week to get back on track.
Cancer immunotherapy has been a huge topic in recent years, and deservedly so. But there are some types of tumors that respond much better than others, which means that there are also some that hardly respond at all. A great deal of effort is going into trying to find ways to make these immunologically "cold" tumors respond to checkpoint inhibitors and other such drugs. One way to do this is thro
The Indian Ocean has been warming much more than other ocean basins over the last 50-60 years. While temperature changes basin-wide can be unequivocally attributed to human-induced climate change, it is difficult to assess whether contemporary heat and freshwater changes in the Indian Ocean since 1980 represent an anthropogenically-forced transformation of the hydrological cycle. What complicates
EPFL researchers have found that a form of neuron-to-neuron communication that has long been dismissed as 'background noise' is required to keep nerve junctions intact as animals age. The finding suggests that defects in this type of neural communication could contribute to neurodegenerative disorders and other brain conditions.
Researchers in the BOTTLE Consortium, including from the National Renewable Energy Laboratory (NREL) and the University of Portsmouth, have identified using enzymes as a more sustainable approach for recycling polyethylene terephthalate (PET), a common plastic in single-use beverage bottles, clothing, and food packaging that are becoming increasingly relevant in addressing the environmental challe
Up to now passenger cars are classified by experts in each country into categories such as micro, small, middle, upper middle, large and luxury class. But this old fashioned method has limitations in terms of compatibility. Moreover, some crossover vehicles are difficult to categorize. Empa scientists found a method to do this sorting fairly and in an efficient way by browsing databases with machi
The second shot of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection, according to a study. The finding strongly supports the view that the second shot should not be skipped. "Despite their outstanding efficacy, little is known about how exactly RNA vaccines work," says Bali Pulendran, professor of pathology and of microbiology and
Despite the best efforts of industry to work towards sustainability, most plastics (or polymers) are still made using non-renewable fossil fuels. However, researchers have now found an economical method for producing biobased acrylate resins. The study, published in the journal Angewandte Chemie, shows how all the synthesis steps, from initial building blocks right up to polymerization, can be car
Retail traders often fear that reducing the amount of urban space made available for parking private vehicles would have a negative effect on their businesses. A survey conducted by researchers from the Institute for Advanced Sustainability Studies (IASS) on two shopping streets in Berlin shows that traders have a skewed perception of their customers' mobility habits. The findings of this research
A team of chemists from the Croatian Ruđer Bošković Institute (RBI) described a new, easy-to-use method for uninterrupted monitoring of mechanochemical reactions. These reactions are conducted in closed milling devices, so in order to monitor the reaction one has to open the reaction vessel, thus interfering with the process. The new method uses Raman spectroscopy to get deeper insight into solid-
On June 29, former South African president Jacob Zuma was sentenced to 15 months in prison for corruption during his presidency. Zuma—the first ethnic Zulu to hold the country's highest office—has a loyal following. He also has many detractors, who blame his administration's corruption for a stagnant economy and weakened democracy. Zuma didn't turn himself in until July 7, saying he was innocent

What can monkeys teach us about stock market bubbles? It turns out that monkeys make decisions much like investors on the trading floor—they develop a herd mentality, mimicking the behavior of others until overinflation and the eventual pop. "This tendency to follow the herd emerges from our social brain networks," explains Michael Platt, professor of neuroscience at the University of Pennsylvani
Physicists are still arguing over whether black holes have " hair ," but we're pretty sure neutron stars have mountains. These dead stars are extreme in every respect, from their magnetic field to gravitational influence, but the only thing extreme about the mountains is how small they are. A new analysis of neutron star physics predicts the "mountains" on the surface are less than a millimeter t

This summer, if you see a butterfly with wings that are blue on top with orange spots underneath, you may have crossed paths with a male European Common Blue (or Polyommatus icarus), a newly introduced species in Canada. Could it be a fluke? Probably not, according to a group of researchers who have taken a close look at this captivating blue creature.
Triggered by the 2015-16 El Niño, extreme drought and associated mega-wildfires caused the death of around 2.5 billion trees and plants and emitted 495 million tons of CO2 from an area that makes up just 1.2 per cent of the entire Brazilian Amazon rainforest, and 0.01 per cent of the whole biome.
New research has found marine seismic surveys used in oil and gas exploration are not impacting the abundance or behaviour of commercially valuable fishes in the tropical shelf environment in north-western Australia.
One in eight children have mental disorders that cause symptoms and impairment and therefore require treatment, but even in high-income countries most of these children will not gain access to services to treat them, reports a study published in the journal Evidence-Based Mental Health.
Although lockdowns are undoubtedly associated with health harms, their impact on health is unlikely to be worse than the impact of the COVID-19 pandemic itself, concludes a review published in the online journal BMJ Global Health.
The case of a patient who experienced two facial palsies – one after the first and another after the second dose of the Pfizer-BioNTech COVID-19 vaccine – strongly suggests that Bell's palsy (facial nerve palsy of unknown cause) is linked to the Pfizer-BioNTech vaccine, doctors write in the journal BMJ Case Reports.
Did you know multiple sclerosis (MS) means multiple scars? New research shows that the brain and spinal cord scars in people with MS may offer clues to why they developprogressive disability but those with related diseases where the immune system attacks the central nervous system do not. Researchers assessed if inflammation leads to permanent scarring in these three diseases.
Tesla has finally rolled out the promised Full Self-Driving (FSD) subscription service. For $199 per month, owners of supported Tesla vehicles will be able to get a taste of the company's most advanced self-driving features. That might not sound like a great deal, but the only option previously was an up-front $10,000 package. However, not all of the Tesla faithful are happy. Some vague language
An observational study in Barcelona, Spain found that implementation of same-day rapid screening, use of face masks, and improved ventilation was associated with very low rates of SARS-CoV-2 transmission at an indoor mass-gathering live concert without physical distancing. The brief research report is published in Annals of Internal Medicine.
How bad could inflation get in the United States? Economist Narayana Kocherlakota has some answers. Kocherlakota says a return to 1970s levels of inflation is unlikely. But he also offers a cautionary note. Inflation refers to the rate of change in the prices of goods and services. But different goods' prices change at different rates. That means the inflation rate depends on how one averages the
Although people in early 2020 were highly cautious about COVID-19, 11 months later the public pushed the envelope on pandemic safety precautions and ignored warnings as time went on, a new University of California, Davis, study suggests.
The link between on-road traffic and air pollution is well-known, as are the negative health impacts of pollution exposure. However, the many factors that may influence commuters' exposure to pollutants—such as frequency, time, and duration of commute—and the overall impact of commuting remains a matter of on-going scientific discovery.
A new study shows how biometric data can be used to find potentially challenging and dangerous areas of urban infrastructure. By analyzing eye-tracking data from cyclists navigating Philadelphia's streets, researchers found that these individual-based metrics can provide a more proactive approach for designing safer roadways for bicyclists and pedestrians.
Some COVID-19 patients who experience acute respiratory failure respond by significantly increasing their respiratory effort — breathing faster and more deeply. There is concern among some doctors that this level of respiratory effort can lead to further damage to these patients' lungs. Working with intensive care clinicians, engineering researchers have used computational modeling to provide new
Researchers at the University of Maryland School of Medicine (UMSOM) launched a new online tool that could more quickly advance medical discoveries to reverse progressive hearing loss.

The nation's largest wildfire torched more dry forest in Oregon and forced the evacuation of a wildlife research station Monday as firefighters had to retreat from the flames for the ninth consecutive day due to erratic and dangerous fire behavior.
Lancaster and Humphreys (1) attempted to identify drivers of plant thermal tolerances by analyzing a newly compiled database of heat and cold tolerances. Lancaster and Humphreys conclude that variation in thermal tolerances is attributable to a combination of phylogeny, geography, and local environment, and that the observed patterns "are not…
The shelterin protein TPP1 is involved in both recruiting telomerase and stimulating telomerase processivity in human cells. Assessing the in vivo significance of the latter role of TPP1 has been difficult, because TPP1 mutations that perturb telomerase function tend to abolish both telomerase recruitment and processivity. The Saccharomyces cerevisiae telomerase-associated…
The quality factor of a passive, linear, small acoustic radiator is fundamentally limited by its volume normalized to the emitted wavelength, imposing severe constraints on the bandwidth and efficiency of compact acoustic sources and of metamaterials composed of arrangements of small acoustic resonators. We demonstrate that these bounds can be…
The phytohormone abscisic acid (ABA) plays a major role in abiotic stress responses in plants, and subclass III SNF1-related protein kinase 2 (SnRK2) kinases mediate ABA signaling. In this study, we identified Raf36, a group C Raf-like protein kinase in Arabidopsis, as a protein that interacts with multiple SnRK2s. A…
The Qinghai-Tibetan Plateau, with low precipitation, low oxygen partial pressure, and temperatures routinely dropping below −30 °C in winter, presents several physiological challenges to its fauna. Yet it is home to many endemic mammalian species, including the plateau pika (Ochotona curzoniae). How these small animals that are incapable of hibernation…
Seismic surveys are used to locate oil and gas reserves below the seabed and can be a major source of noise in marine environments. Their effects on commercial fisheries are a subject of debate, with experimental studies often producing results that are difficult to interpret. We overcame these issues in…
Asian summer monsoon (ASM) variability and its long-term ecological and societal impacts extending back to Neolithic times are poorly understood due to a lack of high-resolution climate proxy data. Here, we present a precisely dated and well-calibrated tree-ring stable isotope chronology from the Tibetan Plateau with 1- to 5-y resolution…
We recently published a pioneering synthesis study of plant thermal macrophysiology (1), revealing global patterns that are in agreement with the main patterns known from animals, as well as with expectations from theory (2, 3). Perez et al. (4) criticize our study, primarily on the basis that differences in experimental…
Blasticidin S is a peptidyl nucleoside antibiotic. Its biosynthesis involves a cryptic leucylation and two leucylated intermediates, LDBS and LBS, have been found in previous studies. Leucylation has been proposed to be a new self-resistance mechanism during blasticidin S biosynthesis, and the leucyl group was found to be important for…
Genome-scale metabolic models (GEMs) are used extensively for analysis of mechanisms underlying human diseases and metabolic malfunctions. However, the lack of comprehensive and high-quality GEMs for model organisms restricts translational utilization of omics data accumulating from the use of various disease models. Here we present a unified platform of GEMs…
Higher order thalamic neurons receive driving inputs from cortical layer 5 and project back to the cortex, reflecting a transthalamic route for corticocortical communication. To determine whether or not individual neurons integrate signals from different cortical populations, we combined electron microscopy "connectomics" in mice with genetic labeling to disambiguate layer…
N6-methyladenosine (m6A) is the most abundant internal messenger RNA (mRNA) modification, contributing to the processing, stability, and function of methylated RNAs. Methylation occurs in the nucleus during pre-mRNA synthesis and requires a core methyltransferase complex consisting of METTL3, METTL14, and WTAP. During herpes simplex virus (HSV-1) infection, cellular gene expression…
Major changes to the operation of local newsrooms—ownership restructuring, layoffs, and a reorientation away from print advertising—have become commonplace in the last few decades. However, there have been few systematic attempts to characterize the impact of these changes on the types of reporting that local newsrooms produce. In this paper,…
RNA viruses exist as genetically heterogeneous populations due to high mutation rates, and many of these mutations reduce fitness and/or replication speed. However, it is unknown whether mutations can increase replication speed of a virus already well adapted to replication in cultured cells. By sequentially passaging coxsackievirus B3 in cultured…
The production of ammonia through the Haber–Bosch process is regarded as one of the most important inventions of the 20th century. Despite significant efforts in optimizing the process, it still consumes 1 to 2% of the worldwide annual energy for the high working temperatures and pressures. The design of a…

You might not think you have acetylcholine on your mind. But technically, you do. That's because acetylcholine is a neurotransmitter that the brain needs for mental processing. And if you've been feeling a little hazy or cloudy lately (and who hasn't?), you might benefit from a brain boost supplement like Acetylcholine Brain Food from Natural Stacks. Research on the subject of neurotransmitters i
We must not assume that we will be able to replicate a vaccine within 12 months during the next pandemic. Even if this was accomplished, other interventions would be required to control and mitigate well before the availability of a vaccine.
George Mason University's Dr. Michelle Williams shares program evaluation results determining the feasibility of offering free, same-day cancer screening and health education to reduce disparities. The program examined how access to free screenings affects participants' knowledge about cancer, self-efficacy for obtaining healthcare, and intentions to change health behaviors. The program had a posi
Even though KRAS4B is the dominant form in cancer, the KRAS4A mutant is also oncogenic, and it is even more active. In the words of the authors, "KRAS4AG12V alone, in the absence of KRAS4B, can induce lung cancer and metastasis in 20 percent of individuals. Our results suggest that for therapies to be effective, the two KRAS isoforms should be targeted."
Research conducted at the Sharon Eccles Steele Center for Translational Medicine (SCTM) at the University of Utah's John A. Moran Eye Center explains why people carrying a block of genetic variants strongly associated with the development of age-related macular degeneration (AMD) may develop the disease and identifies a potential therapeutic pathway for slowing or even reversing disease progressio
New Curtin University-led research has called into question existing health advice that mothers wait a minimum of two years after giving birth to become pregnant again, in order to reduce the risk of adverse pregnancy outcomes, such as preterm and small-for-gestational age births.
Adult children's educational attainment has an impact on their parents' mental and physical health, according to a new study. The researchers used a new wave of data from a survey launched in 1994 to further extend the geometry linking educational attainment and health that demonstrates another dimension of the intergenerational effects of completing college. "By analyzing these data we arrived a
In dinosaurs' heyday in the late Cretaceous Period roughly 78 million years ago, Earth's climate was both warmer and more varied than what we have known before, researchers report. Dinosaurs of the northern mid-latitudes (45 degrees north of the equator) experienced average summer temperatures of 27 degrees Celsius (about 80 degrees Fahrenheit). Winters were roughly 15 degrees C (59 degrees F). T
Under some circumstances, gestures can improve the accuracy of people's descriptions of object size relative to their estimations based on sight, research on the Müller-Lyer illusion finds. For example, imagine describing the precise dimensions of a common object, such as a coin, for another person. Do you move your hand, pretending to pick one up to show its size? If so, you likely aren't alone.
A suite of International Space Station scientific experiments soon journey back to Earth aboard the 22nd SpaceX commercial resupply services mission for NASA.
