A research team elucidates the aggregation mechanism of the Alzheimer protein tau.

The use of opioids to soothe the pain of a pulled tooth could be drastically reduced or eliminated altogether from dentistry, say researchers.

Despite Mercury's 400 C daytime heat, there is ice at its caps, and now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice.

Scientists have identified the mechanism that allows skin cells to sense changes in their environment, and very quickly respond to reinforce the skin's outermost layer. The findings provide insight into how errors in this process might lead to skin conditions like psoriasis.

Researchers discover the enzyme SPRK1's role in reorganizing the paternal genome during the first moments of fertilization -- a finding that might help explain infertility cases of unknown cause.

Researchers have developed a new method to analyze particulate matter more precisely than ever before. With its help, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other suspended particulate matter. Their findings will help to improve the understanding of global processes involved in cloud formation and...

Researchers have developed a technique to accurately measure the winding arms of spiral galaxies that is so easy, virtually anyone can participate. This new and simple method is currently being applied in a citizen science project, called Spiral Graph, that takes advantage of a person's innate ability to recognize patterns, and ultimately could provide researchers with some insight into how...

Just like humans and other animals, plants have hormones. One role of plant hormones is to perceive trouble and then signal to the rest of the plant to respond. A multicenter team is reporting new details about how plants respond to a hormone called jasmonic acid, or jasmonate. The findings could help researchers develop crops that are hardier and more able to withstand assault, especially in an...

Current guidance on coronavirus 'largely ignores' the implications for public health and clinical responses in light of those most at risk, according to an international group of global health experts.

A research team has found that nanoscale particles of the most commonly used plastics tend to move through the water supply, especially in fresh water, or settle out in wastewater treatment plants, where they end up as sludge, in landfills, and often as fertilizer.

Researchers have uncovered the mechanism by which Epo acts in nerve cells.

As outbreaks of COVID-19 disease caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue worldwide, there's reassuring evidence that children have fewer symptoms and less severe disease.

Researchers have uncovered stem cell-activated mechanisms of healing after a heart attack. Stem cells restored cardiac muscle back to its condition before the heart attack, in turn providing a blueprint of how stem cells may work.

Ten years after producing the first sample of the now widely studied family of nanomaterials, called MXenes, researchers have discovered a different way to make the atom-thin material that presents a number of new opportunities for using it. The new discovery removes water from the MXene-making process, which means the materials can be used in applications in which water is a contaminant or...

Using a mouse model, researchers demonstrated the formation of fear memory involves the strengthening of neural pathways between two brain areas: the hippocampus, which responds to a particular context and encodes it, and the amygdala, which triggers defensive behavior, including fear responses.

A research team confirmed the occurrence of biomagnification of toxic substance TPT compounds along the marine food chain resulted in very high concentrations of TPT in two top predators, the Chinese white dolphin and the finless porpoises. This is the first study in the world to confirm the trophic magnification of TPT in food webs of cetacean species.

A new article shows people perform better in VR exercise games when they compete against a realistic avatar of themselves.
