Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst. Read more ›

Lung tumors called adenocarcinomas sometimes respond to initially effective treatments by transforming into a much more aggressive small cell lung cancer (SCLC) that spreads rapidly and has few options for treatment. Researchers have developed a mouse model that illuminates this problematic process, known as histological transformation. The findings advance the understanding of how mutated genes can trigger cancer evolution and suggest targets for more effective treatments. Read more ›

A new technique can control a larger number of microscopic defects in a diamond. These defects can be used as qubits for quantum sensing applications, and being able to control a greater number of qubits would improve the sensitivity of such devices. Read more ›

Researchers have identified a new way to harness the antioxidant and antibacterial properties of a botanical compound to make nanofiber-coated cotton bandages that fight infection and help wounds heal more quickly. Read more ›

A novel PET imaging technique can noninvasively detect active inflammation in the body before clinical symptoms arise, according to new research. Using a PET tracer that binds to proteins present on activated immune cells, the technique produces images of ongoing inflammation throughout the body, such as rheumatoid arthritis. This makes it easier for physicians to correctly diagnose and treat patients. Read more ›

The absence of a single immune cell receptor has been linked to both fewer defenses against mycobacterial infections, such as TB, and damaging buildup of sticky residue in the lungs. Read more ›

Researchers report the results of the first ever genome-wide association study (GWAS) of a biosafety level 4 (BSL-4) virus. The team found two key human genetic factors that could help explain why some people develop severe Lassa fever, and a set of LARGE1 variants linked to a reduced chance of getting Lassa fever. The work could lay the foundation for better treatments for Lassa fever and other similar diseases. The... Read more ›

People with aphasia have more trouble coming up with words they want to use when they're prompted by images and words that carry negative emotional meaning, new research suggests. Read more ›

Health care providers in developing countries know that oral rehydration salts (ORS) are a lifesaving and inexpensive treatment for diarrheal disease, a leading cause of death for children worldwide -- yet few prescribe it. A new study suggests that closing the knowledge gap between what treatments health care providers think patients want and what treatments patients really want could help save half a million lives a year and reduce unnecessary...

The Greenland ice sheet lies thousands of miles from North America yet holds clues to the distant continent's environmental history. Nearly two miles thick in places, the ice sheet grows as snow drifts from the sky and builds up over time. But snow isn't the only thing carried in by air currents that swirl around the atmosphere, with microscopic pollen grains and pieces of ash mixing with snowfall and preserving... Read more ›

Researchers have discovered a previously unknown ability of a group of immune system cells, known as Atypical B cells (ABCs), to fight infectious diseases such as malaria. The scientists say ABCs could also be key to developing new treatments for chronic autoimmune conditions such as lupus. Read more ›

In a survey involving a total of 2,472 respondents, researchers asked participants about nonpolitical and political moral behavior and nonpolitical and political moral tolerance. They found people more willing to behave badly in political contexts -- and more willing to tolerate bad behavior among potliticians they support. Read more ›

Scientists have discovered that nighttime air pollution -- coming primarily form car exhaust and power plant emissions -- is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings show how nighttime pollution creates a chain of chemical reactions... Read more ›

If you're looking for a long-term relationship or to boost your social status, lower your pitch, according to researchers studying the effects of voice pitch on social perceptions. They found that lower voice pitch makes women and men sound more attractive to potential long-term partners, and lower voice pitch in males makes the individual sound more formidable and prestigious among other men.

For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of heat flow in superconductors and neutron stars. Read more ›

A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing. Read more ›

ETH Zurich researchers have developed a new method of magnetic resonance imaging (MRI) for the early detection and better monitoring of multiple sclerosis (MS). The method maps the myelin sheaths in the brain more precisely than was previously possible. The loss of myelin sheaths is a hallmark of MS. The new MRI method with its special head scanner could also be used by researchers to better visualise other solid tissue... Read more ›

An advanced human heart organoid system can be used to model embryonic heart development under pregestational diabetes-like conditions, researchers report. The organoids recapitulate hallmarks of pregestational diabetes-induced congenital heart disease found in mice and humans. The findings also showed that endoplasmic reticulum (ER) stress and lipid imbalance are critical factors contributing to these disorders, which could be ameliorated with exposure to omega-3s.
