Researchers have designed and demonstrated a technology that can block cyberattacks from impacting the nation's electric power grid.

A chemical and biomolecular engineer is rethinking the traditional use of glucagon as an emergency response by administering it as a preventive measure.

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.

Scientists have found new evidence of menopause in killer whales - raising fascinating questions about how and why it evolved.

A news study shows soil microbes boost 'hybrid vigor,' a well-known phenomenon where crosses between inbred lines of corn and other crops produce offspring that outperform their parents in yield, drought resistance and other desirable qualities.

Ten years after one of the largest nuclear accidents in history spewed radioactive contamination over the landscape in Fukushima, Japan, a new study has shown that radioactive contamination in the Fukushima Exclusion Zone can be measured through its resident snakes.

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.

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.

Forensics specialists can use a commercial assay targeting mitochondrial DNA to accurately discriminate between wolf, coyote and dog species. The genetic information could aid authorities in prosecuting hunting jurisdiction violations and preserving protected species.

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.

Alzheimer's disease and other forms of neurodegeneration can be identified using a combination of biomarkers in cerebrospinal fluid of living patients, researchers find.

To better understand how familiarity impacts social fishes, a group of research scientists studied this idea using schooling coral reef fish.

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.

BOTTLE Consortium effort develops model that finds sizeable energy and carbon-saving benefits for recycling PET, a common plastic used in bottles, clothing, carpet.

Scientists develop algorithms that predict the output of solar cells, easing their integration into existing power grids.

Certain regions of the SARS-CoV-2 genome might be a suitable target for future drugs, researchers have found. With the help of dedicated substance libraries, they have identified several small molecules that bind to certain areas of the SARS-CoV-2 genome that are almost never altered by mutations.

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.

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.

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...

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.

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...

One of the leading thinkers in nano-science has called on the energy materials community to help finally put an end to the world's reliance on fossil fuels.

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.

Decreasing bacterial acidity could help reduce antimicrobial resistance by eliminating bacteria that can survive being treated with antibiotics.
