Novel autophagy research traces new mammalian pathways and reveals unexpected impact of SARS-CoV-2 infection.

COVID-19 saliva testing kits that include a novel preservative can also be used measure microscopic organisms in the mouth, a new study has found. This enables study of the relationship between mouth and lung microbes and the SARS-CoV-2 virus that may allow for the development of new treatments.

Researchers have developed a novel vaccine that in guinea pigs offers protection against infection by the bacterium that causes Lyme disease and may also combat other tick-borne diseases, they report. Instead of triggering an immune response against a particular pathogen, the new vaccine prompts a quick response in the skin to components of tick saliva, limiting the amount of time that ticks have...

A team of evolutionary biologists and biomedical researchers lay out evolutionary and biomedical evidence showing that humans, who evolved to live many decades after they stopped reproducing, also evolved to be relatively active in their later years. The researchers say that physical activity later in life shifts energy away from processes that can compromise health and toward mechanisms in the...

With wildfires devastating mountain ecosystems across the western United States, their successful forest revegetation recovery hinges on, among other factors, an adequate lasting snowpack, according to new research.

A scientist has discovered a method for detecting and better defining meteorite impact sites that have long lost their tell-tale craters. The discovery could further the study of not only Earth's geology but also that of other bodies in our solar system.

By the late 21st century, northeastern U.S. cities will see worsening hurricane outcomes, with storms arriving more quickly but slowing down once they've made landfall. As storms linger longer over the East Coast, they will cause greater damage along the heavily populated corridor, according to a new study.

How can we better diagnose blood diseases? A research group aims to answer this question with artificial intelligence (AI). Their goal is to facilitate the time-consuming analysis of bone marrow cells under the microscope. The researchers developed the largest open-source database on microscopic images of bone marrow cells to date. They use it as the basis for an AI model with high potential for...

Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-spread aerosolized particles.

Poor sleep in the over 50s is linked to more negative perceptions of aging, which in turn can impact physical, mental and cognitive health, new research has revealed. A study found that people who rated their sleep the worst also felt older, and perceived their own physical and mental aging more negatively.

Astronomers have discovered two previously invisible galaxies 29 billion light-years away. Their discovery suggests that up to one in five such distant galaxies remain hidden from our telescopes, camouflaged by cosmic dust. The new knowledge changes perceptions of our universe's evolution since the Big Bang.

Identical twins share the same DNA, but one twin can suffer from type 2 diabetes while the other twin does not develop the disease. Researchers have now discovered that there are differences in gene activity in twins where only one sibling had developed the disease. The discovery could contribute to the development of new treatment methods.

Researchers have developed a wearable device to detect and reverse an opioid overdose. The device, worn on the stomach like an insulin pump, senses when a person stops breathing and moving, and injects naloxone, a lifesaving antidote that can restore respiration.

Scientists have succeeded in creating an experimental model of an elusive kind of fundamental particle called a skyrmion in a beam of light.

The question of the causes of species extinction confronts science with complex tasks.

A white dwarf star that completes a full rotation once every 25 seconds is the fastest spinning confirmed white dwarf, according to a team of astronomers.

Since the discovery of quasicrystals (QCs), solids that mimic crystals in their long-range order but lack periodicity, scientists have sought physical properties related to their peculiar structure. Now, an international group of researchers report a long-range magnetic order in QCs with icosahedral symmetry that turn ferromagnetic below certain temperatures. This groundbreaking discovery opens...

Researchers explain why digital teaching cannot replace face-to-face teaching in university education, but can certainly be seen as a complementary tool. The future of teaching and learning may lie in so-called blended learning, a mix of face-to-face and online education.

To successfully cooperate or compete with other people in everyday life, it is important to know what the other person thinks, feels, or wants. Researchers have explored which strategies people use to understand other people.

Volcanic gases are helping researchers track large-scale movements in Earth's deep interior. Scientists have discovered anomalous geochemical compositions beneath Panama.

By integrating multiple sensory inputs, a loop of mutual inhibition among a small set of neurons allows worms to switch between long-lasting behavioral states.

A combined experimental and computational study shows promising results for a new class of catalysts producing ammonia under mild conditions.

When it comes to your health, being willing to give social support to your spouse, friends and family may be just as important as receiving assistance, a new study suggests.

The gold complex auranofin has traditionally been used for treating rheumatism but is also being evaluated as a treatment for certain forms of cancer. Researchers now show that other molecules that inhibit the same biological system have a more specific effect than auranofin and therefore may have greater potential as cancer therapies.
