During infections, the immune system needs to distinguish foreign antigens that are expressed by invading bacteria and viruses from self-antigens that are expressed by cells of the body. If not, the immune system can mistakenly attack its own cells, causing lasting damage to tissue and potential long-term disease. New research from the University o

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form of microbes. With computer assistance, the researchers assembled these fragments like puzzle pieces to compile the entire genome. It was only then tha

Researchers at the National Institutes of Health (NIH) have developed eye drops that extend vision in animal models of a group of inherited diseases that lead to progressive vision loss in humans, known as retinitis pigmentosa. The eye drops contain a small fragment derived from a protein made by the body and found in the […]

A long-term Switzerland-wide study has found that neighbourhoods with numerous, well-arranged trees exhibit lower mortality risks than other areas. The reasons behind this, and the factors that play a role, will require further research. Beyond creating a serene and open atmosphere in urban areas, trees and parks also contribute to human well-being

An experimental drug appears to reduce the risk of Alzheimer’s-related dementia in people destined to develop the disease in their 30s, 40s or 50s, according to the results of a study led by the Knight Family Dominantly Inherited Alzheimer Network-Trials Unit (DIAN-TU), which is based at Washington University School of Medicine in St. Louis.

Engineers have designed robots that crawl, swim, fly and even slither like a snake, but no robot can hold a candle to a squirrel, which can parkour through a thicket of branches, leap across perilous gaps and execute pinpoint landings on the flimsiest of branches. University of California, Berkeley, biologists and engineers are trying to […]

A new study explains how a parakeet’s brain helps it to mimic human words. By recording for the first time the brain activity of parakeets as they made sounds, a research team at NYU Grossman School of Medicine found that their brains generate patterns seen before only in humans as they speak. Published online March […]

If a person hides their own hand and focuses on a rubber hand instead, they may perceive it as part of their own body under certain conditions. What sounds like a gimmick could one day be used to help patients who suffer from chronic pain: Researchers at the Clinic for Psychosomatic Medicine and Psychotherapy at […]

A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, according to a new study led by researchers at Penn State. The research team used data from NASA’s Transiting Exoplanet Survey Satellite (TESS) to study young sub-Neptunes — planets bigger than Earth but [&helli

A predator’s gotta eat, but sometimes what they eat harms people sharing the landscape, and that often leads to the carnivore’s death. Fortified corrals are one strategy used in Tanzania to protect both livestock and vulnerable carnivore species. But then where do lions, leopards and hyenas go for dinner? Do they feed on the next [&hell

Alternative RNA splicing is like a movie editor cutting and rearranging scenes from the same footage to create different versions of a film. By selecting which scenes to keep and which to leave out, the editor can produce a drama, a comedy, or even a thriller — all from the same raw material. Similarly, cells […]

Adding immunotherapy to a new type of inhibitor that targets multiple forms of the cancer-causing gene mutation KRAS kept pancreatic cancer at bay in preclinical models for significantly longer than the same targeted therapy by itself, according to researchers from the Perelman School of Medicine at the University of Pennsylvania and Penn Medicine&

In Nature Neuroscience, UConn School of Medicine researchers have revealed a new scientific clue that could unlock the key cellular pathway leading to devastating neurodegenerative diseases like Alzheimer’s disease, and the progressive damage to the brain’s frontal and temporal lobes in frontotemporal degeneration (FTD) and the associat

Astronomers have discovered two exoplanets around TOI-1453, a star about 250 light years away. These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from our system. This discovery paves the way for future atmospheric studies to better understand these types of planets. Astrophysicists have once again enric

Life may not have begun with a dramatic lightning strike into the ocean but from many smaller “microlightning” exchanges among water droplets from crashing waterfalls or breaking waves. New research from Stanford University shows that water sprayed into a mixture of gases thought to be present in Earth’s early atmosphere can lead

A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and molecules, a fundamental process in physics that has implications for various fields including x-ray generation and plasma physics. Think about atoms — the building blocks of everything around us. Sometimes, they lose

Mount Sinai researchers have developed a method to uncover the hidden immune cells that harbor the human immunodeficiency virus (HIV), a discovery that brings medical experts one step closer to a cure for the infection affecting nearly 40 million people globally. The findings were published in Nature Communications on March 6. HIV is a virus [&hell

When major storms hit Houston last spring and summer, losing power was a nightmare for residents, but for many, the financial fallout was just as devastating. A new report from Rice University’s Kinder Institute for Urban Research finds that more than half of Houston-area workers lost income due to these storms, either because they couldnR
