Researchers have produced high-quality biodiesel after ‘feeding’ and growing microalgae on leftover coffee grounds.

UV light makes it possible to see intricate structures of fossils that are barely visible in normal daylight. This method has often been used on the fossilized seashells from the Earth’s current geological era to reveal patterns of color that had long …

Peering inside common atmospheric particles is providing important clues to their climate and health effects, according to a new study by chemists. Secondary organic aerosol (SOA) particles are ubiquitous in the atmosphere and play an important role in…

Adults who were making lifestyle changes to lose weight tended to overestimate how healthy their diet was, according to a new study. In addition, self-perceptions of how much their diet improved over the course of the 12- month study were often inaccur…

Common gut bacteria can enhance the effects of cocaine in mice, researchers report. Their study demonstrates how cocaine use supports the growth of the bacteria, which in turn eat up a chemical, glycine, that contributes to normal brain function. As le…

The urge to vomit after eating contaminated food is the body’s natural defensive response to get rid of bacterial toxins. However, the process of how our brain initiates this biological reaction upon detecting the germs remains elusive. For the first t…

When two musical notes are played simultaneously, the human ear can perceive weak additional tones called combination tones. While less perceivable, objective combination tones are also generated by some musical instruments. Researchers have now used v…

The destruction of red blood cells, or mechanical hemolysis, is an inevitable complication of interventional devices, so scientists want to gain a better understanding of the phenomenon. Researchers develop a red blood cell destruction model based on s…

Researchers have catalogued thousands of sites in the brain where RNA is modified throughout the human lifespan in a process known as adenosine-to-inosine (A-to-I) editing, offering important new avenues for understanding the cellular and molecular mec…

On September 26, NASA’s Double Asteroid Redirection Test (DART) spacecraft crashed into Dimorphos, a moonlet of the near-Earth asteroid Didymos, at 14,000 miles per hour. Prior to the impact, engineers and scientists performed an experiment to study th…

Surgical care experts have today unveiled two studies that will help to provide safer surgery for thousands of patients around the world — particularly in Low- and Middle-income Countries (LMIC).

One dose of an antibody drug safely protected healthy, non-pregnant adults from malaria infection during an intense six-month malaria season in Mali, Africa, a National Institutes of Health clinical trial has found. The antibody was up to 88.2% effecti…

Researchers have found that COVID-19 activates the same inflammatory response in the brain as Parkinson’s disease. The discovery identified a potential future risk for neurodegenerative conditions in people who’ve had COVID-19, but also a possible trea…

In the tough war against glioblastoma, scientists are taking a cue from viruses on how to make the aggressive cancer more vulnerable to treatment. Their target is SAMHD1, a protein which can protect us from viral infections by destroying an essential b…

By scrutinizing over a century’s worth of photos, University of Cambridge researchers have made the first ever measurements that show rhinoceros horns have gradually decreased in size over time.

Using holograms created in digital microscopes and interpreted using artificial intelligence (AI), for the first time researchers can now follow the lives of microplankton at the individual level.

Quantum dots are clusters of some 1,000 atoms which act as one large ‘super-atom’. It is possible to accurately design the electronic properties of these dots just by changing their size. A team has succeeded in making a highly conductive optoelectroni…

Researchers have developed a new method for determining which genes are relevant to the aging process. The work was done in an animal species widely used as a model for genetic and biological research, but the finding has broader applications for resea…

Communication is everything — and that applies for algae, too. However, their chemical language and its significance in aquatic ecosystems remain largely unknown. New research summarizes the current state of knowledge and identifies new approaches for…
