Scientists created metafabric using nanotechnology. It works by reflecting light and UV rays. This protects the wearer and keeps them cool in extreme sun. In the future with extremely sunny climate expectations this could reduce AC usage (which is harmful to the environment) and protect people.
In addition to antibodies and white blood cells, the immune system deploys peptides to fight viruses and other pathogens. Synthetic peptides could reinforce this defense but don't last long in the body, so researchers are developing stable peptide mimics. Today, scientists report success in using mimics known as peptoids to treat animals with herpes virus infections. These small synthetic molecule

XXL Space Station China is reportedly working on a "ultra-large spacecraft" that would be so large that it would span entire miles, according to the South China Morning Post . The project is still many years out, but the National Natural Science Foundation of China is calling on scientists to figure out how to construct such a massive structure in orbit. It's a massive undertaking — but given the
During World War II, Nazi Germany and the U.S. were racing to develop nuclear technology. Before Germany could succeed, Allied forces disrupted the program and confiscated some of the cubes of uranium at the heart of it. The ultimate fate of most of that uranium is unknown, but a few cubes thought to be associated with the program are in the U.S. and Europe. Today, scientists report initial result
A ground-breaking detector that aims to use quartz to capture high frequency gravitational waves has been built by researchers at the ARC Centre of Excellence for Dark Matter Particle Physics (CDM) and the University of Western Australia.
Genetic effects associated with same-sex sexual behavior are also associated with a mating advantage among people who engage only in opposite-sex sexual behavior, according to a study involving participants from the United States and United Kingdom published in Nature Human Behaviour. However, the authors caution that the genetic differences studied here are small, are spread throughout the human
Coffee drinkers intuitively recognize the pleasure of swallowing a smooth, rich brew versus a watery one. Aside from added cream or sugar, the coffee itself contributes to this sensation—referred to as body or mouthfeel—but the specific compounds are not well defined. Now, researchers report several coffee compounds that contribute to the feeling of the beverage coating the inside of the mouth, as

After months of anticipation, Americans have a fully licensed COVID-19 vaccine. Today, the FDA announced the approval of Pfizer-BioNTech's shot for people 16 and older—the first complete thumbs-up among the three vaccines available in the U.S. The pervasive mood has been: Finally . Pfizer's shot was given its emergency use authorization—the vaccine's training wheels—back in December, and the comp
Study reinforces the hard evidence that carbon emissions are the main cause of worsening extreme weather The record-shattering rainfall that caused deadly flooding across Germany and Belgium in July was made up to nine times more likely by the climate crisis, according to research. The study also showed that human-caused global heating has made downpours in the region up to 20% heavier. The work

Australian space company Southern Launch will
The United States finds itself, once again, in a grave situation. The COVID-19 pandemic is once again killing more 1,000 people in the country every single day, according to The New York Times ' online tracker — and that death toll is now spiking into what looks like one of the most deadly waves yet. That's a threshold that we haven't crossed since late March 2021, when we were finally recovering
When Neuralink co-founder Max Hodak announced his enigmatic departure from the company earlier this year, it was unclear whether he quit due to disagreements with fellow co-founder Elon Musk or if he was fired for moving too slow on clinical trials. Now, Futurism has learned, Hodak is working on what appears to be a well-funded new brain interface venture called Science Corp. According to an SEC
Close Calls Earlier this month, a free-floating iceberg nearly 500 square miles in size almost crashed into Antarctica — a near-miss that could have further fragmented the already-crumbling ice shelf. The European Space Agency's Copernicus Sentinel-1 spacecraft watched as the A-74 iceberg swung around and just narrowly avoided colliding with the Brunt Ice Shelf over the past two weeks, according
Total Recall GM just issued a recall for the Chevrolet Bolt that, when taken into account alongside two previous recalls, now encompasses every single Bolt that the company has ever made. The new recall, which was announced on Friday by the National Highway Traffic Safety Administration, encompasses every model year 2019-2022 Bolt because the batteries have the unfortunate tendency to catch fire
Take Two Earlier this month, NASA's prized Mars rover Perseverance totally fumbled the ball during its first attempt to collect rock samples to send back to Earth. NASA preemptively celebrated when the rover dug through a rock that the agency nicknamed Roubion, but was left scrambling for answers when the sample tube was still empty after the attempted collection. NASA initially blamed the rock —
Neuroscientists are the cartographers of the brain's diverse domains and territories — the features and activities that define them, the roads and highways that connect them, and the boundaries that delineate them. Toward the front of the brain, just behind the forehead, is the prefrontal cortex, celebrated as the seat of judgment. Behind it lies the motor cortex, responsible for planning and…

Researchers from the Graduate School of Engineering, Osaka City University have succeeded in storing electricity with the voltage generated from the conversion phenomenon of ferromagnetic resonance (FMR) using an ultra-thin magnetic film of several tens of nanometers.
F or those of us wondering what kind of superpower China might be, we'll soon get some clues in, of all places, Afghanistan. In the aftermath of the American departure, how Beijing handles relations with Kabul—whether it can forge economic ties with the Taliban, how much political and diplomatic sway it seeks, and, most crucial, if it can use its leverage to influence the new regime—could offer a
In mid-June this year, some brands of cat food were recalled as a precaution after a sudden increase in cases of feline pancytopenia, a rare blood disease that can be fatal. Shivani Dave speaks to Daniella Dos Santos, a practicing small animal and exotic pet vet and the senior vice-president of the British Veterinary Association, to understand what the food recall means for cat owners, and to fin
A team of researchers at Carnegie Mellon University has found that like humans, rhesus macaques can choke when facing a high-stakes situation. In their paper published in Proceedings of the National Academy of Sciences, the group describes experiments they conducted involving training rhesus monkeys to carry out increasingly difficult tasks for increasingly large rewards.
The construction of population-based variomes has contributed substantially to our understanding of the genetic basis of human inherited disease. Here, we investigated the genetic structure of Turkey from 3,362 unrelated subjects whose whole exomes (n = 2,589) or whole genomes (n = 773) were sequenced to generate a Turkish (TR)…
M ore than 20 years ago , I sat down to talk with a Black cop from New York City. He had a weightlifter's powerful hands, a quick-trigger tongue, and a scar on the back of his shaved head from his days in a youth gang. At the time, the relationship between police officers and Black residents was raw. This was Rudy Giuliani's New York, where a white New York cop sodomized a suspect with his baton
Roughing It As the space tourism industry prepares to take off, NASA astronaut Megan McArthur issued a warning to the wealthy passengers that they shouldn't expect a particularly glamorous journey. McArthur compared surviving space travel to being an explorer back on Earth: toughing uncomfortable and dangerous situations for the sake of better understanding the unknown. "I think it's a little bit

Scientists from The University of Manchester have managed to successfully make actinide metals form molecular actinide-actinide bonds for the first time, opening up a new field of scientific study in materials research.
Astronomers have used ESA's XMM-Newton spacecraft to investigate the overionized recombining plasma in a supernova remnant (SNR) known as IC 443. Results of this research, published August 12 on arXiv.org, deliver essential information about the origin of this plasma in the studied SNR.
The Boston genetic engineering company Ginkgo Bioworks and its CEO, Jason Kelly, have been spectacularly successful selling a story: that synthetic biology will transform the manufacture of physical products. What computers did for information, Kelly says, biology will do for the physical world. Instead of making a chemical from petroleum, why not have Ginkgo's multi-floor "foundry" in Boston's s

If evolution is a numbers game, the coronavirus is especially good at playing it. Over the past year and a half, it's copied itself quickly and sloppily in hundreds of millions of hosts, and hit upon a glut of genetic jackpots that further facilitate its spread. Delta, the hyper-contagious variant that has swept the globe in recent months , is undoubtedly one of the virus's most daring moves to d
Sortie will not take place until after SpaceX cargo run this weekend and Russian spacewalks in September Nasa is delaying a spacewalk at the International Space Station because of a medical issue involving one of its astronauts. Officials announced the postponement on Monday, less than 24 hours before Mark Vande Hei was supposed to float outside. Continue reading…
Females and males differ in many ways and yet they share the same genome. The only exception is the male Y chromosome. Using beetles as a study system, new research from Uppsala University, now published in Nature Ecology & Evolution, shows that despite the Y chromosome containing very few genes, it can dramatically change male body size and thus facilitate the evolution of sex differences.
Being able to detect DNA from a single cell is important for the detection of diseases and genetic disorders. Measuring single DNA molecules has been possible for some time; however, directly detecting samples at the point of extraction with no need for subsequent steps has not. Now, researchers at SANKEN, Osaka University have demonstrated a method of releasing DNA at the point of measurement. Th
The "megadrought" impacting the Colorado River system this year has been devastating to the 40 million people who rely on it for water. But could this drought have been predicted? Will we be able to predict the next one?
Findings may help explain why incidence of bowel cancer is rising among younger adults in developed regions Children of women who were overweight or obese when pregnant have a higher risk of developing bowel cancer in later life, research suggests. Obesity in women has previously been linked to health problems in their offspring . Among them, studies have suggested women who are overweight when t
Last week, I attended my first film screening that required proof of vaccination against COVID-19 upon entry. I presented my Excelsior Pass and photo ID and swanned on in. The entire process took 15 seconds, and in return I received the invaluable assurance that my fellow cinemagoers had also been inoculated. My experience was in line with New York City policy , which mandates proof of vaccinatio
Our bodies are home to several bacterial species that help us maintain our health and wellbeing. Thus, engineering these good bacteria to alter the activity of genes gone awry, either by turning them down or by activating them, is a promising approach to improve health and combat diseases.
Galaxies—massive collections of gas, dust, and billions of stars and their solar systems—are a fundamental component of our Universe. Understanding how they have formed and evolved over cosmic eras remains one of the greatest challenges of modern astronomy.
Amyloid plaques found in the retinas of eyes may be an indicator of similar plaques in the brain, a hallmark of Alzheimer's disease, and may provide a more visible biomarker for detecting disease risk.
Pinched Nerve NASA revealed yesterday that Mark Vande Hei, a current crew member on the International Space Station, suffered a "minor medical issue" that caused Tuesday's scheduled spacewalk to be delayed. While NASA said that the issue was "not a medical emergency" and didn't respond to Futurism's request for comment, we've finally heard from Vande Hei himself via his Twitter account, who says
Astronomers have used Saturn's rings as a giant seismometer to learn about the interior of the planet. The gas giant is constantly in flux, and shifts can trigger ripples in the planet's rings. Exactly why the planet is in flux remains a mystery. How can you tell what the inside of another planet is like? If it's a rocky planet like Mars, we could have a lander place a seismometer on the surface
A new type of lithium-metal battery reaches an extremely high energy density of 560 watt-hours per kilogram — based on the total weight of the active materials — with a remarkable stability. Researchers used a promising combination of cathode and electrolyte: The nickel-rich cathode enables storage of high energy per mass, the ionic liquid electrolyte ensures largely stable capacity over many cy
The Arctic has been warming more than twice as fast as the rest of the planet. Meanwhile CO2 measurements show substantial increases in the amount of carbon absorbed into and emitted by Arctic plants and soil. Scientists assumed this was playing a large role in changes to the Arctic carbon cycle. But they were not able to measure carbon uptake and release independently. This study provides insight
A pair of scale model structures subjected to simulated storm conditions in an Oregon State University lab responded like real wood-frame homes during recent hurricanes, suggesting model buildings can yield important design information for low-lying areas vulnerable to storm surges and big waves.
Researchers have developed a prototype display that uses projection to create large-scale 3D images with ultra-high definition. The new approach helps overcome the limitations of light-field projection, which can create natural-looking 3D images that don't require special 3D glasses for viewing.
The heaviest known elements are the so-called "superheavy" elements, those with atomic numbers greater than 103. These elements are found only in laboratories, where they are made by fusing together two lighter elements. This process is unlikely to occur, so scientists have only tiny amounts (a few atoms) for experiments, and chemists are interested in the chemical properties of these elements. Ho
Researchers at the University of Colorado Boulder have designed one of the most precise stopwatches yet—not for timing Olympic sprinters and swimmers, but for counting single photons, or the tiny packets of energy that make up light.
When Kīlauea Volcano erupted in 2018, lava covered parts of the Island of Hawaii, but a volcanic smog, known as "vog," inundated it. The vog contained dangerous levels of fine particulate matter and sulfur dioxide gas, which threatened the health of the downwind population on the island.

But the figures tell only a fraction of the story. Continue reading…
The development of the cerebral cortex relies on the controlled division of neural stem and progenitor cells. The requirement for precise spatiotemporal control of proliferation and cell fate places a high demand on the cell division machinery, and defective cell division can cause microcephaly and other brain malformations. Cell-extrinsic and…
Insect development is cooperatively orchestrated by the steroid hormone ecdysone and juvenile hormone (JH). The polycomb repressive complex 2 (PRC2)–mediated histone H3K27 trimethylation (H3K27me3) epigenetically silences gene transcription and is essential for a range of biological processes, but the functions of H3K27 methylation in insect hormone action are poorly understood….
Mesopredator release theory suggests that dominant predators suppress subordinate carnivores and ultimately shape community dynamics, but the assumption that subordinate species are only negatively affected ignores the possibility of facilitation through scavenging. We examined the interplay within a carnivore community consisting of cougars, coyotes, black bears, and bobcats using contemporaneous
Numerous animal lineages have maternally inherited symbionts that are required for host reproduction and growth. Endosymbionts also pose a risk to their hosts because of the mutational decay of their genomes through genetic drift or to selfish mutations that favor symbiont fitness over host fitness. One model for heritable endosymbiosis…
A cell wall made of the heteropolymer peptidoglycan (PG) surrounds most bacterial cells. This essential surface layer is required to prevent lysis from internal osmotic pressure. The class A penicillin-binding proteins (aPBPs) play key roles in building the PG network. These bifunctional enzymes possess both PG glycosyltransferase (PGT) and transpeptidase…
The popularly reported energy storage mechanisms of potassium-ion batteries (PIBs) are based on alloy-, de-intercalation-, and conversion-type processes, which inevitably lead to structural damage of the electrodes caused by intercalation/de-intercalation of K+ with a relatively large radius, which is accompanied by poor cycle stabilities. Here, we report the exploration of…
ECOLOGY, ENGINEERING Correction for "Infrared optical and thermal properties of microstructures in butterfly wings," by Anirudh Krishna, Xiao Nie, Andrew D. Warren, Jorge E.

An adolescent's day can be filled with a dizzying array of digital technologies. For many teenagers, being online is a way to pass the time and communicate with friends. Cell phones and social media can also help teens cope with stressful events — as long as they strike the right balance between spending time online and pursuing other coping activities.
Compare human social behavior at a country level and you will find differences. Japan has the highest score whereas the Netherlands is just above average. This is what psychologist Niels van Doesem discovered in research with an international team of 64 colleagues in 61 industrialized countries. Their findings have published in PNAS.
Tropical ecosystems are known for high species diversity. Adaptations permitting niche differentiation enable species to coexist. Historically, research focused primarily on morphological and behavioral adaptations for foraging, roosting, and other basic ecological factors. Another important factor, however, is differences in sensory capabilities. So far, studies mainly have focused on the…
Granular excavation is the removal of solid, discrete particles from a structure composed of these objects. Efficiently predicting the stability of an excavation during particle removal is an unsolved and highly nonlinear problem, as the movement of each grain is coupled to its neighbors. Despite this, insects such as ants…
The atmospheric history of molecular hydrogen (H2) from 1852 to 2003 was reconstructed from measurements of firn air collected at Megadunes, Antarctica. The reconstruction shows that H2 levels in the southern hemisphere were roughly constant near 330 parts per billion (ppb; nmol H2 mol−1 air) during the mid to late…
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has killed more than 4 million humans globally, but there is no bona fide Food and Drug Administration–approved drug-like molecule to impede the COVID-19 pandemic. The sluggish pace of traditional therapeutic discovery is poorly suited to producing targeted treatments against rapidly evolving viruses….
Humans are social animals, but not everyone will be mindful of others to the same extent. Individual differences have been found, but would social mindfulness also be shaped by one's location in the world? Expecting cross-national differences to exist, we examined if and how social mindfulness differs across countries. At…
Cellular senescence causes a dramatic alteration of chromatin organization and changes the gene expression profile of proinflammatory factors, thereby contributing to various age-related pathologies through the senescence-associated secretory phenotype (SASP). Chromatin organization and global gene expression are maintained by the CCCTC-binding factor (CTCF); however, the molecular mechanism under
Biotic conflict can create evolutionary arms races, in which innovation in one group increases selective pressure on another, such that organisms must constantly adapt to maintain the same level of fitness. In some cases, this process is driven by conflict among members of the same species. Intraspecific conflict can be…
Exercise and circadian biology are closely intertwined with physiology and metabolism, yet the functional interaction between circadian clocks and exercise capacity is only partially characterized. Here, we tested different clock mutant mouse models to examine the effect of the circadian clock and clock proteins, namely PERIODs and BMAL1, on exercise…
How did people change their behavior over the different phases of the UK COVID-19 restrictions, and how did these changes affect their risk of being exposed to infection? Time-use diary surveys are unique in providing a complete chronicle of daily behavior: 24-h continuous records of the populations' activities, their social…
Skeletal muscle atrophy is caused by various conditions, including aging, disuse related to a sedentary lifestyle and lack of physical activity, and cachexia. Our insufficient understanding of the molecular mechanism underlying muscle atrophy limits the targets for the development of effective pharmacologic treatments and preventions. Here, we identified Krüppel-like factor…
Observational knowledge of the epidemic intensity, defined as the number of deaths divided by global population and epidemic duration, and of the rate of emergence of infectious disease outbreaks is necessary to test theory and models and to inform public health risk assessment by quantifying the probability of extreme pandemics…
Mycobacterium tuberculosis (Mtb) infection is difficult to treat because Mtb spends the majority of its life cycle in a nonreplicating (NR) state. Since NR Mtb is highly tolerant to antibiotic effects and can mutate to become drug resistant (DR), our conventional tuberculosis (TB) treatment is not effective. Thus, a novel…
Active nitrifiers and rapid nitrification are major contributing factors to nitrogen losses in global wheat production. Suppressing nitrifier activity is an effective strategy to limit N losses from agriculture. Production and release of nitrification inhibitors from plant roots is termed "biological nitrification inhibition" (BNI). Here, we report the discovery of…
Based on a survey of 200 papers, Kay et al. (1) argue that many modeling results on the evolution of helping are likely due to kin selection, although this was not acknowledged by the original authors. Our work (2) on the evolution of indirect reciprocity is one of the papers…
The aim of our paper (1) is to evaluate whether all impactful published models where altruism evolves (or can evolve under some range of model parameter values) are based on a life cycle with local reproduction and local interactions leading to interacting individuals being genetically related. In their response (2),…
We investigate a nonrelativistic version of Georgi's "unparticle physics." We define the unnucleus as a field in a nonrelativistic conformal field theory. Such a field is characterized by a mass and a conformal dimension. We then consider the formal problem of scatterings to a final state consisting of a particle…
In high-stakes situations, people sometimes exhibit a frustrating phenomenon known as "choking under pressure." Usually, we perform better when the potential payoff is larger. However, once potential rewards get too high, performance paradoxically decreases—we "choke." Why do we choke under pressure? An animal model of choking would facilitate the investigation…

Working out the ancient history of Earth is hard because evidence keeps getting ground up within the planet. A new technique fills in some important blanks in the history of the planet's critical magnetosphere. Every 200 million years, it seems, the magnetosphere weakens and then strengthens. Life, at least as we know it, requires a relatively radiation-free place to thrive and a breathable atmos
Carnivorous animals lack key genes needed to detect and respond to infection by pathogens, a study has found. Farming large numbers of carnivores, like mink, could allow the formation of undetected 'disease reservoirs', in which a pathogen could spread to many animals and mutate to become a risk to human health.
There's been an age-old question going back to Darwin's time about the relationships among the world's five living rhinoceros species. One reason answers have been hard to come by is that most rhinos went extinct before the Pleistocene. Now, researchers have helped to fill the gaps in the rhino evolutionary family tree by analyzing genomes of all five living species together with the genomes of th
While moving around within the gas in the interstellar medium, cosmic rays kickstart the background protons, which causes a collective plasma wave movement akin to ripples on a lake. The big question is how cosmic rays deposit their momentum into the background plasma. Plasma astrophysicists review recent developments within the field of studying the streaming instability triggered by cosmic rays,
Wind power has experienced fast growth within China during the past decade, but many wind farms are being built within regions of high seismic activity. Researchers are now exploring the dynamic behaviors of wind turbines subjected to combined wind-earthquake loading. The group discovered that changes in the wind increase and decrease the response amplitude of the wind turbine under weak and stron
Researchers work on physicochemical properties and antioxidant activity of wood vinegar and tar fraction in bio-oil produced from hazelnut shells pyrolysis at 400 degrees Celsius to 1,000 C. The researchers found the wood vinegar and tar left over after burning the shells contained the most phenolic substances, which laid a foundation for the subsequent research on antioxidant properties.
Viruses do not always kill the cells they infect. Researchers have discovered in experiments with mice that cells have the power to self-heal and eliminate viruses. However, these cells undergo long-term changes. The findings may provide a hint as to why cured hepatitis C patients are more susceptible to liver cancer for years after.
Among adolescents ages 10 to 14 in the U.S, the overall rate of drug use remained relatively stable in the first six months of the COVID-19 pandemic. However, one change was a decreased use of alcohol, but an increased use of nicotine and misuse of prescription drugs.
Prof J Kiley Hamlin from the International Congress for Infant Studies calls into question a study showing impaired cognition in children, and says there is reason to be optimistic about their resilience Results from a scientific paper have been racing around the internet like wildfire, perhaps because they confirm parents' worst fears: infants born during the pandemic show a large and significan
Prey animals perform a diverse variety of behaviors to escape from predators, but whether specific behaviors are used to escape from predators that represent different types of threat has been long-debated. New research from the University of Minnesota College of Biological Sciences shows that predators' hunting techniques and the relative degree of danger they pose are key factors dictating anti-
A new study has found that the likelihood of owning your own home and becoming a parent has fallen in recent years, with young people just as likely to become parents while living in private rented accommodation. In previous eras, people were more likely to become parents after they became homeowners.
Harvesting wild mushrooms requires an expert eye to distinguish between the delicious and the poisonous, which makes products with truly wild mushrooms expensive. However, due to minimal regulations around the harvest and sale of wild fungi, it's nearly impossible to know what mushroom species are included in the product. A new study used DNA barcoding to show that 16 food products labeled with wi
Five months into the pandemic, things were getting desperate for Robin Betancourt, The tourists he depended upon as a boat captain were unable to visit the Galapagos Islands, whose isolation—1,000 kilometers (600 miles) from the mainland—makes alternative employment hard to find.
In a testament to its resiliency, happiness, according to this year's World Happiness Report , remained remarkably stable around the world, despite a pandemic that upended the lives of billions of people. As a classicist , I find such discussions of happiness in the midst of personal or societal crisis to be nothing new. " Hic habitat felicitas " – "Here dwells happiness" – confidently proclaims
It's been a truth for a long time: if you want to study the movement and behavior of single atoms, electron microscopy can give you what X-rays can't. X-rays are good at penetrating into samples—they allow you to see what happens inside batteries as they charge and discharge, for example—but historically they have not been able to spatially image with the same precision electrons can.
A regenerative and socially responsible approach to food production and distribution is crucial to long-term food security and fundamental to our ecological and human well-being, according to a study by an acclaimed researcher at Clemson University.
The functionality of nanoparticles in a host of applications, including drug delivery and nano-optics, is often dictated by their mass and size. Measuring these properties simultaneously for the same nanoparticle has also been challenging.
Fewer than one hundred kilometers lie between the flood-ravaged district of Ahrweiler and the volcanic lakes in the Eifel. These maars have now provided evidence that weather extremes could increase. Researchers at Johannes Gutenberg University Mainz (JGU) and the Max Planck Institute for Chemistry have used sediment cores from maar lakes and dry maars in the volcanic Eifel to precisely construe h
"From the evolutionary perspective, the human brain evolved to feel first and think later," says neuroscientist and marketing consultant Terry Wu. The part of our brain that controls emotions (the limbic system) and the part that deals with rational thought (the frontal cortex) can send conflicting signals, which leads to bad decision-making. Stress, easy access to online shopping platforms, and
The potential protective effect of sirtuin enzymes in age-related diseases, including cardiovascular diseases, remains an area of intense investigation. Now, researchers has determined that sirtuin 1 (SIRT1) and sirtuin 3 (SIRT3) levels decline in aging hearts, disrupting the ability of cardiac muscle cells (cardiomyocytes) to contract in response to ischemia-reperfusion injury.
A new paper undercuts renewed claims of cannibalism in the Caribbean. In January 2020, a prestigious scientific journal published a paper that revived a long-discredited theory, first suggested by the explorer Christopher Columbus : A group of marauding cannibals from South America descended on islands of the Caribbean circa CE 800, terrorizing local populations. "…their erroneous suggestion of c
Nature Communications, Published online: 24 August 2021; doi:10.1038/s41467-021-25300-4 Material production accounts for a quarter of global greenhouse gas emissions. Here, the authors show that resource efficiency and circular-economy strategies can allow for cumulative emission reductions of 20–52 Gt CO2-eq from residential buildings and 13–26 Gt CO2e-eq from cars by 2050.
A team of researchers at the University of Sydney has found that invasive cane toad tadpoles have given their species an advantage in Australia by eating the hatchlings of native toads. In their paper published in Proceedings of the National Academy of Sciences, the group describes how they tested the willingness of cane toad tadpoles to consume competitors and whether it gave them an advantage.
In addition to needs such as food, water, shelter, and medical care, social contact is an important aspect of welfare for animals, just as it is for humans. Yet early socialization of dairy calves is sometimes given lesser priority in the interest of physical health, with young calves housed individually to prevent the spread of contagious diseases such as those that cause diarrhea, or scours, a m
The Antarctic Ice Sheet, Earth's southern polar ice sheet, has grown and receded and grown again over millions of years. This changing mass influences the planet's climate and sea levels, with historic data recorded in sediment, meltwater and surrounding oceans. However, the remote and difficult nature of the sheet leaves researchers with limited access to collect samples and data that may reveal
A new report released today by Rangahau Mātauranga o Aotearoa | NZCER and Te Kura o Te Mātauranga, Institute of Education, at Massey University shows children have a natural ability to survive, thrive and learn during COVID-19 lockdowns.
After the 9/11 terrorist attacks, U.S. President George W. Bush's approval ratings shot up from near 50 percent to over 80 percent. High-profile, international terrorist attacks typically produce this effect, which political scientists call a "rally 'round the flag"—constituents increase their support for incumbent presidents and prime ministers when their country is met with a serious national se
Jonathan Gilligan, associate professor of Earth and environmental sciences and civil and environmental engineering, and a group of international researchers have illustrated potential international conflicts over climate change.
Norway experiences dangerous landslides due to its clay-rich soil. For her Master's thesis in civil engineering at EPFL, Mathilde Metral outlined steps that the country's geotechnical engineers can take to improve the predictive computer model they're currently developing.
The world's first professional police force, The London Metropolitan Police, deterred crime and brought a significant reduction in violent crimes when it was introduced nearly 200 years ago. By using historical data, a new economics study examines the relationship between policing and crime levels.

While more production companies are now making drama series in Australia, they are making substantially fewer than they were in 1999 and foreign conglomerates are taking a bigger share of the drama pie says new research led by QUT. And it's only going to get worse.
Tails come in all shapes and sizes and can be used for all sorts of things. For instance, tails can help with locomotion, to keep balance, and to communicate with others. Some tails are even able to grasp an object firmly and allow the animal to hang its full body weight on it. These tails are called prehensile, an adaptation found among some monkeys, seahorses—and chameleons.
People who survived SARS in 2003 and who got the Pfizer-BioNTech mRNA vaccine produce antibodies that can neutralize all known SARS-CoV-2 variants of concern, plus other animal coronaviruses that have the potential to infect humans, research finds.

Blödningar i magtarmkanalen är vanliga efter en akut hjärtinfarkt. Forskare har identifierat åtta faktorer som ökar risken. Blödningar i den övre delen av magtarmkanalen utgör en stor andel av blödningskomplikationerna efter akut hjärtinfarkt. Tillståndet kräver stora resurser från sjukvården, och bidrar till ett ökat lidande och ökad dödlighet. Dessutom begränsar blödningskomplikationer användan
When its battery is fully charged, an electronic device will normally indicate that it is at 100% capacity. However, this value only represents 70–90% of the theoretical energy density that can be stored in the batteries, owing to the permanent loss of Li ions that occurs during the initial charge in the stabilization (formation) stage of battery production. By preventing this initial loss of Li i
Immune cells have many jobs to do: Some identify infected cells and eliminate them. Others help rein in inflammation to prevent damage to healthy tissue. And many are critical components of cancer treatment. Researchers know that the specialized receptors of a type of immune cell called a T cell help regulate T cells' activity and immune roles. A new computational method called CoNGA, published to
NASA's new Perseverance rover hasn't even been on the red planet long enough to get dusty, so everything it does is still big news.

Water "blisters" trapped beneath the thick interior of Greenland's ice sheet could provide critical insight into the hydrological network coursing deep below Earth's second largest body of ice—and how it might be destabilized by climate change, according to a new study.
Using energy from solar modules and wind turbines, water can be split by electrolysis into its constituents hydrogen and oxygen without producing any dangerous emissions. As the availability of energy from renewable sources varies when producing green, i.e. CO2-neutral, hydrogen, it is very important to know the behavior of the catalysts under high loading and dynamic conditions.
America's system of national parks is among the best ideas that the country ever had. While they are a remarkable achievement, they are not representative of all biodiversity that exists, and they are not connected to each other. We must physically connect them so ecosystems can adapt to climate change. Constructing a World Park that connects global protected areas could be achieved with as littl

Issues of war and peace, racism, sexism, homophobia, xenophobia, and economic oppression are the result of humans interacting with other humans. These dysfunctions are as old as humanity, and they cause great pain and suffering. As an optimist, I hope they are receding, but as a realist, I know they will never go away. While humans have always battled, as my colleague Peter Coleman has observed, m
