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 …

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. T…

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 t…

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…

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-sprea…

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 percei…

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 pe…

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 develope…

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 r…

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 l…

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 a…
