Researchers have devised an ingenious method of using acoustics to conceal and simulate objects.
Previous fires may hold the key to predicting and reducing the severity of future wildfires in the western United States as fire activity continues to increase, according to researchers.
Scientists reveal new approaches to manipulating light absorption in optical resonators by different types of optical losses.
The effects of monsoon rainfall on food insecurity in Nepal vary by earthquake exposure, with regions that experienced both heavy earthquake shaking and abundant rainfall more likely to have an inadequate supply of nutritious food, according to new research.
A team of researchers is using a novel technique to comb through the data and to reconstruct major branches in the linguistic tree.
A decades-long study of introduced voles on the Norwegian islands of Svalbard is helping to answer a longstanding puzzle of Arctic ecology -- what drives the well-established population cycles of small Arctic mammals, such as voles and lemmings. These plant-eating rodents are among the most populous Arctic mammals. The results suggest the importance of predators as a primary factor driving the...
A new study into cognitive control promises to be the first of many aimed at understanding its origins in the brain and its variations between people and among groups.
CD8+ T cells -- known as "killer" T cells -- are the assassins of the immune system. Once they are primed, they seek out and destroy other cells that are infected with virus or cells that are cancerous. Priming involves dendritic cells -- sentinels of the immune system. In an influenza infection in the lungs, for example, lung-migratory dendritic cells capture a piece of the viral antigen, and...
Researchers from Newcastle University, UK have engineered Escherichia coli bacteria to capture carbon dioxide (CO2) using hydrogen gas (H2) to convert it into formic acid. The research, published today in Applied and Environmental Microbiology raises the possibility of converting atmospheric CO2 to commodity chemicals.
The diversity of human languages can be likened to branches on a tree. If you're reading this in English, you're on a branch that traces back to a common ancestor with Scots, which traces back to a more distant ancestor that split off into German and Dutch. Moving further in, there's the European branch that gave rise to Germanic; Celtic; Albanian; the Slavic languages; the Romance languages like...
The eyes have it. They are constantly on the move when viewing scenes in augmented reality (AR).
h-index, g-index, i10 index, m-quotient, Journal Impact Factor, Altmetrics … it's long been an intractable issue plaguing the research community—how to assess the relative merits of research objectively across disciplines and make fair comparisons between early career and established researchers, different genders, and even different research disciplines.
The measurement of the effects of space-relevant stresses on organisms, and fundamental research into the underlying mechanisms of those effects, are core components of NASA's Space Biology Program. These stresses include galactic cosmic radiation (GCR), solar particle events (SPEs), and reduced gravity. Notably, to date, biological experiments in space have mainly been conducted within Low...
NASA announces the award of 10 grants or cooperative agreements for exciting new Space Biology research that will advance NASA’s understanding of how living systems respond, acclimate, and adapt to the space environment in support of human space exploration. As human exploration prepares to go beyond Low Earth Orbit, Space Biology is shifting its research...
Like a spider trapping its prey, our immune system cells cooperate to capture and "eat" bacteria.
Making eye contact repeatedly when you're talking to someone is common, but why do we do it? When two people are having a conversation, eye contact occurs during moments of "shared attention" when both people are engaged, with their pupils dilating in synchrony as a result, according to a Dartmouth study published in the Proceedings of the National Academy of Sciences.
A decades-long study of voles on the Norwegian archipelago of Svalbard is offering insights into a longstanding puzzle of Arctic ecology—effectively, what drives the well-established population cycles of small Arctic mammals, such as voles and lemmings.

US researchers say teenagers are more likely to get vaccine-related myocarditis than end up in hospital with CovidCoronavirus – latest updatesSee all our coronavirus coverageHealthy boys may be more likely to be admitted to hospital with a rare side-effect of the Pfizer/BioNTech Covid vaccine that causes inflammation of the heart than with Covid itself, US researchers claim.Their analysis of...
The Ig Nobels are a reminder that Jonathan Swift was wrong about reason. Without research driven by curiosity, there would be far fewer breakthroughsIn Gulliver’s Travels, Jonathan Swift mocked the assumption that the scientific revolution had transformed European culture for the better. The satirical novel, published in 1726, has its eponymous hero stumbling upon “the Academy” in the...
Natural and manmade physical structures all lose energy, and scientists work hard to eliminate that loss or compensate for it. Optical and photonic devices lose energy through light scattering, radiation or material absorption. In some situations, however, intentionally yet carefully designing loss in open optical devices and systems can lead to unconventional physical phenomena which inspires...
A new silicon chip can decode any error-correcting code through the use of a novel algorithm known as Guessing Random Additive Noise Decoding (GRAND).
Researchers claim that previous calculations of ICT's share of global greenhouse emissions, estimated at 1.8-2.8%, likely fall short of the sector's real climate impact as they only show a partial picture. The researchers point out that some of these prior estimates do not account for the full life-cycle and supply chain of ICT products and infrastructure -- such as: the energy expended in...
Researchers find that machine-learning algorithms can identify effective behavioral, educational, and psychological interventions more accurately than professionals can.
Humans acknowledge that personality goes a long way, at least for our species. But scientists have been more hesitant to ascribe personality to other animals. A study has now documented personality in golden-mantled ground squirrels, which are common across the western U.S. and Canada.
A new conducted in both mice and a small group of patients with advanced cancers has shown that so-called 'cold' tumors that are nearly devoid of immune cells -- and therefore unresponsive to immunotherapy -- can be turned 'hot' with extremely low doses of radiation and the rational use of existing therapies.
School-aged children who spend more time in front of screens are only slightly more likely to have attention disorders, disturbed sleep or lower grades and are no more likely to suffer from depression and anxiety. Meanwhile, they tend to have more close friends.
Large carnivore populations are expanding across Europe and experts are calling for increased support for communities to encourage harmonious relationships with their new neighbors.
The increasing use of photoinitiators, especially in medical settings, has raised concerns about their adverse effects on human health. Now, scientists have shown that three photoinitiators -- 1-HCHPK, MBB, and MTMP -- show estrogen-like activity in mice and increase the growth of breast cancer tumors in these animals. Their results warn against the use of such chemicals in medical instruments...
An international team of researchers developed the largest and most detailed simulation of the Universe to date and has made it freely available on the cloud to everyone. This simulation, named Uchuu, will help astronomers to interpret results from Big Data galaxy surveys.
Scientists report a vampire fish attached to the body of an Amazonian thorny catfish. Very unusually, the candirus were attached close to the lateral bone plates, rather than the gills, where they are normally found. Since the hosts were not badly harmed, and the candirus apparently derived no food benefit, scientists believe this association is commensalistic rather than parasitic.
