Interactions between iron, water, oxygen and ions quickly become complex. Scientists have now developed a more precise method to observe how iron minerals like rust form.

Researchers are carrying the field of microscopy a step further, refining a technique known as cryogenic electron microscopy, or cryo-EM.

The massive columns of smoke generated by a nuclear war would alter the world's climate for years and devastate the ozone layer, endangering both human health and food supplies, new research shows. The international study draws on newly developed computer climate modeling techniques to paint an even grimmer picture of a global nuclear war's aftermath than previous analyses.

Oxytocin, a naturally occurring hormone that acts as a chemical messenger in the brain, showed no evidence of helping children with autism gain social skills, according to a large national study.

Two independent studies have illuminated unexpected substructures in the fundamental components of all matter. Preliminary results using a novel tagging method could explain the origin of the longstanding nuclear paradox known as the EMC effect. Meanwhile, authors will share next steps after the recent observation of asymmetrical antimatter in the proton.

Researchers are building symbiotic 'underwater gardens' in the Pacific Ocean to show how different species of coral can work together to possibly restore degraded reefs.

In areas where COVID-19 vaccines are limited, vaccinating essential workers before older adults can reduce infections and deaths, according to a modeling study.

New research suggests that dengue -- a viral infection spread by mosquitos -- could be suppressed in Singapore in a highly cost-effective manner through the release of mosquitos infected with the bacterium Wolbachia.

In patients with COVID-19, a high body mass index (BMI) is associated with an increased risk of death and prolonged intensive care unit (ICU) stay, according to a new study.

For nearly a decade, scientists have known that HIV integrates itself into genes in cells that have the potential to cause cancer. And when this happens in animals with other retroviruses, those animals often develop cancer. But, perplexingly and fortunately, that isn't regularly happening in people living with HIV. A new study reveals why doctors aren't seeing high rates of T cell lymphomas -- or...

At the beginning of neurodegenerative disease, the immune cells of the brain -- the 'microglia' -- take up glucose, a sugar molecule, to a much greater extent than hitherto assumed. These results are of great significance for the interpretation of brain scans depicting the distribution of glucose in the brain. Furthermore, such image-based data could potentially serve as a biomarker to...

Direct evidence that microtubules function as mechano-sensors and regulate the intracellular transport of molecules has been reported, leading to new possibilities in the fields of biomechanics, medicine, and biosensors.

An international team of astronomers recently observed more than 1,650 fast radio bursts (FRBs) detected from one source in deep space, which amounts to the largest set -- by far -- of the mysterious phenomena ever recorded. The source, dubbed FRB 121102, was observed using the Five-hundred-meter Aperture Spherical Telescope (FAST) in China, and represents more FRBs in one event than all previous...

Physicists have made the most precise measurement of the neutron's lifetime, which may help answer questions about the early universe.

During the COVID-19 pandemic, addiction treatment providers rapidly pivoted to providing services via telehealth. New research highlights the potential for telehealth delivery to increase patient engagement by improving access and convenience. However, it also finds limited evidence that telehealth results in better retention or other outcomes relative to in-person treatment.

Testing pooled saliva samples twice weekly for SARS-CoV-2 on a residential college campus yielded a greater than 95 percent agreement with the gold standard for accuracy -- nasopharyngeal diagnostic samples tested singly.

Mutations linking liver disease with obesity and diabetes have been identified, leading to new understanding about how systemic diseases interact.

Normal human esophagus carries a high number of mutations, but tumors are rare, due to mutant cells eliminating early tumors.

This improved technological platform can be used to develop new treatments, molecular diagnosis strategies or vaccines for various diseases.

Researchers can now detect brand new mutations in individual malaria parasites infecting humans. Such high resolution could help us understand how parasites develop drug resistance and evade immune responses, and suggest potential treatment targets.

Trillions of benign bacteria live in the intestine. They are kept in a continuous balance by the immune system, which thereby makes them harmless to humans. Researchers have been able to show how certain natural antibodies keep these bacteria in check. The findings could make an important contribution to the development of superior vaccines.

More than half of the 236 million people who have been diagnosed with COVID-19 worldwide since December 2019 will experience post-COVID symptoms -- more commonly known as 'long COVID' -- up to six months after recovering, according to researchers. The research team said that governments, health care organizations and public health professionals should prepare for the large number of COVID-19...

Biologists have found that mother roundworms can pass stress signals to future generations. The biologists report a mother roundworm exposed to a stressor can even under certain conditions pass the memory of that exposure to their grandchildren.

Solar prominences hover above the visible solar disk like giant clouds, held there by a supporting framework of magnetic forces, originating from layers deep within the Sun. The magnetic lines of force are moved by ever-present gas currents -- and when the supporting framework moves, so does the prominence cloud. A research team has observed how magnetic forces lifted a prominence by 25,000...
