Asian Americans who experienced increased acts of racism at the start of the COVID-19 pandemic were more likely to acquire firearms and ammunition for self-defense, according to a study by researchers at the University of Michigan and Eastern Michigan University.

A heat wave gripping parts of the nation added an exclamation point to a series of announcements this week about the world's warming climate.

An international team of scientists is using porous, sponge-like materials that can trap carbon dioxide in their cavities while allowing other gases such as nitrogen to pass through.

Engineers at University of California Riverside are the first to report selective breakdown of a particularly stubborn class of PFAS, called fluorinated carboxylic acids (FCAs), by common microorganisms.

Slashing emissions of carbon dioxide, by itself, cannot prevent catastrophic global warming. But a new study concludes that a strategy that simultaneously reduces emissions of other largely neglected climate pollutants would cut the rate of global warming in half and give the world a fighting chance to keep the climate safe for humanity.

Ten years ago, a new technology called CRISPR-CAS9, made it possible for scientists to change the genetic code of living organisms. As revolutionary as it was, the tool had its limitations. Like the first cell phones that could only perform one function, the original CRISPR method can perform one function: removing or replacing genes in a genetic sequence. Later iterations of CRISPR were developed for another function that allowed scientists to change gene expression by turning them on or off, without removing them from the genome. Читать дальше...

Researchers have discovered in two-dimensional conductive systems a new effect that promises improved performance of terahertz detectors.

Foreign fishing fleets, as well as international seafood trade, are diverting vital micronutrients away from malnourished populations, a new study reveals.

More than a third of the world's population lives in drylands, areas that experience significant water shortages. Scientists and engineers at The University of Texas at Austin have developed a solution that could help people in these areas access clean drinking water.

It is widely understood that thawing permafrost can lead to significant amounts of methane being released. However, new research shows that in some areas, this release of methane could be a tenth of the amount predicted from a thaw. The research was conducted in Sweden by an international group that includes researchers from the University of Copenhagen. A crucial, yet an open question is how much precipitation the future will bring.

Unusually well-preserved reef corals from the Geological and Paleontological Collection at Leipzig University hold a great secret: They allow us to travel far into the past and reconstruct climatic conditions in our latitudes. Researchers from Leipzig University, the Universities of Bremen and Greifswald, and UniLaSalle in Beauvais have now succeeded in doing just this. Using chemical analyses, they were able to model seasonal temperature fluctuations of this period and show for the first time that... Читать дальше...

Leptospirosis, a disease that dogs can get from drinking water contaminated with Leptospira bacteria, can cause kidney failure, liver disease and severe bleeding into the lungs. Early detection of the disease is crucial and may mean the difference between life and death.

A new Rice University study showcases the severity of discriminatory behavior toward Asians and Asian Americans driven by the COVID-19 pandemic.

Co-workers who team up to solve problems or work on projects can benefit when they have less in common and take turns spotlighting their different expertise, according to new research from The University of Texas at Austin. The findings have implications for how managers can better form and manage teams so all voices are heard.

Because of their proximity to the ocean, Californians get to enjoy locally-sourced oysters, mussels, abalone and clams. Most of the shellfish consumed here come from aquaculture farms along the coast—from San Diego to Humboldt County. And because the animals are filter feeders that siphon tiny plankton out of seawater, growing them is environmentally sustainable.

People who deny the existence of structural racism are more likely to exhibit anti-Black prejudice and less likely to show racial empathy or openness to diversity, according to research published by the American Psychological Association.

An unprecedented wealth of information has been gathered on SARS-CoV-2 in a very short period. This information is primarily focused on the cellular entry process and mechanism of antibody recognition where mainly protein-protein interactions occur.

Sodium metal batteries (SMBs) have attracted extensive attention because of their high theoretical capacity (1166 mAh/g), low redox potential (−2.71 V vs. SHE), high natural material abundance, and low cost. However, the growth of dendrites results in poor battery performance and severe safety problems, inhibiting the commercial application of SMBs.

Topological ideas have recently taken the center stage of modern electromagnetics. Typical topological photonic systems are based on nonreciprocal materials, a class of materials that enables asymmetric light–matter interactions. In particular, nonreciprocal platforms may support unidirectional channels that allow propagation in a given direction of space—let's say from left to right, but not the other way around. Such unidirectional guides are of key importance in optical systems because their modular... Читать дальше...

A group of high school students used a tiny, inexpensive computer to try to measure Earth's magnetic field from the International Space Station, showing a way to affordably explore and understand our planet.

A laser pulse that sidesteps the inherent symmetry of light waves could manipulate quantum information, potentially bringing us closer to room temperature quantum computing.

During a gunshot, two sound events occur: the muzzle blast and the supersonic shock wave. Acoustic sensors, such as arrays of microphones, can capture these sounds and use them to approximate the location of a shooter.

Although racetracks can be fun for communities, they usually come with very high levels of noise that can sour nearby neighborhoods to the experience.

Jobs data showed small declines in unemployment for people with and without disabilities in April, according to Friday's National Trends in Disability Employment (nTIDE) COVID Update. The April data also showed that the number of workers still on temporary layoff remained relatively unchanged, which may reflect persistent delays in the supply chain, according to nTIDE expert Andrew Houtenville, Ph.D., professor of economics at the University of Hampshire (UNH) and research director of the UNH Institute on Disability.

Research from the lab of Matthew Lew at Washington University in St. Louis offers entirely new ways to see the very small.
