SARS-CoV-2, the virus that causes COVID-19, can relieve pain, according to a new study by University of Arizona Health Sciences researchers.
The finding may explain why nearly half of people who get COVID-19 experience few or no symptoms, even though they are able to spread the disease, according to the study's corresponding author Rajesh Khanna, PhD, a professor in the College of Medicine - Tucson's Department of Pharmacology.
UNIVERSITY PARK, Pa. -- The songs that crickets and katydids sing at night to attract mates can help in monitoring and mapping their populations, according to Penn State researchers, whose study of Orthoptera species in central Pennsylvania also shed light on these insects' habitat preferences.
"We were surprised to find more species in suburban areas than in either urban or rural areas," said the study's lead researcher, D.J. McNeil, postdoctoral fellow in Penn State's Insect Biodiversity Center and the Department of Entomology.
Researchers at Princeton University have developed a tool that flags potential biases in sets of images used to train artificial intelligence (AI) systems. The work is part of a larger effort to remedy and prevent the biases that have crept into AI systems that influence everything from credit services to courtroom sentencing programs.
GAINESVILLE, Fla. --- New research shows the glaring light in human-altered landscapes, such as livestock pastures and crop fields, can act as a barrier to big-eyed birds, potentially contributing to their decline.
Scientists at Scripps Research have comprehensively mapped how a key class of proteins within cells regulates signals coming in from cell surface receptors.
The study reveals, among other things, that people commonly have variants in these proteins that cause their cells to respond differently when the same cell receptor is stimulated--offering a plausible explanation for why people's responses to the same drugs can vary widely.
As Australia's aged care sector continues to be scrutinised, researchers at the University of South Australia show that plain solutions are often the best, with a new study finding that aged care residents can improve their nutrition intake simply by increasing their meal sizes.
Assessing the effectiveness of environmental cues within an aged-care home - music, fragrance and other health information - researchers discovered that if residents were offered larger meals, they would eat more, thereby increasing energy and nutrition levels.
Global energy consumption in 2050 could be reduced to the levels of the 1960s and still provide a decent standard of living for a population three times larger, according to a new study.
The study led by the University of Leeds has estimated the energy resource needed for everyone to be provided decent living standards in 2050 - meaning all their basic human needs such as shelter, mobility, food and hygiene are met, while also having access to modern, high quality healthcare, education and information technology.
Researchers from Tokyo Medical and Dental University (TMDU) and Niigata University identify a novel mechanism by which tumors progress
Tokyo, Japan - Tumor cells constantly interact with the cellular environment they live in, affecting tumor progression and metastasis. In a new study, researchers from Tokyo Medical and Dental University (TMDU) and Niigata University discovered that the proteins transforming growth factor-β (TGF-β) and tumor necrosis factor alpha (TNF-α) promote the development of cancer-associated fibroblasts, which in turn contribute to tumor progression.
A research team led by Professor TAKUMI Toru of Kobe University's Graduate School of Medicine (also a Senior Visiting Scientist at RIKEN Center for Biosystems Dynamics Research) have identified 'social cells' in the brain that are related to social behavior. The cells were identified via Ca imaging (*1) conducted using a microendoscope (*2). It is expected that further research will illuminate the neural network for decision-making in social behavior.
These research findings were published in the American scientific journal 'PLOS Biology' on September 21.

New Edith Cowan University (ECU) research has found 94 per cent of Australians caring for a loved one with dementia are sleep deprived.
This can potentially lead to poor health of the carer and may also impact on their ability to provide care for the person living with dementia.
Poor sleep is associated with negative physical and psychological outcomes including hypertension, obesity, mood disorders and dementia.
Physical Review X recently reported on a new optical resonator from the Technion - Israel Institute of Technology that is unprecedented in resonance enhancement. Developed by graduate student Jacob Kher-Alden under the supervision of Professor Tal Carmon, the Technion-born resonator has record-breaking capabilities in resonance enhancement.
COVID-19 has turned 2020 into a nightmare for many people, as they struggle with health problems, economic uncertainty and other challenges. Now a team of researchers in Finland has evidence that the pandemic really is a bad dream.
Foreign interference in U.S. elections likely focuses, in part, on creating distrust among Americans, with paralyzing the American political process as its main goal, according to a new RAND Corporation report.
Recent efforts by Russia to meddle in U.S. elections are based largely on strategies developed by the Soviet Union during the Cold War, and partly aim to elicit strong reactions and drive people to extreme positions to lower the odds they will reach a consensus -- a bedrock of American democracy.
Communications in space demand the most sensitive receivers possible for maximum reach, while also requiring high bit-rate operations. A novel concept for laser-beam based communications, using an almost noiseless optical preamplifier in the receiver, was recently demonstrated by researchers at Chalmers University of Technology, Sweden.
Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is an important step towards ecologically sustainable energy storage.
