Scientists have identified coronaviruses closely related to SARS-CoV-2 from two bats sampled in Cambodia more than a decade ago.

New research in the tiny nematode worm, C. elegans, has revealed that muscle may be a protected tissue under conditions of dietary restriction.

A new study is showing how value choices are recorded in our brains. Researchers found that persistency allows value signals to be most effectively represented, or 'coded,' across different areas of the brain, especially in a critical area within the cerebrum known as the retrosplenial cortex.

Aspirin use is associated with a 26% raised risk of heart failure in people with at least one predisposing factor for the condition.

Good news for those of us who can't face the day without their morning flat white: a long-term study has revealed drinking higher amounts of coffee may make you less likely to develop Alzheimer's disease.

A new 'image analysis pipeline' is giving scientists rapid new insight into how disease or injury have changed the body, down to the individual cell. It's called TDAExplore, which takes the detailed imaging provided by microscopy, pairs it with a hot area of mathematics called topology, which provides insight on how things are arranged, and the analytical power of artificial intelligence to give, for example, a new perspective on changes in a cell resulting from ALS and where in the cell they happen, according to a cell biologist involved with the study.

A new vaping study shows that, like smoking, use of e-cigarettes is linked to dysregulation of mitochondrial genes and immune response genes.

Scientists have advanced knowledge about how two proteins fit together to form a pore that Shigella uses to invade intestinal cells. Targeting these proteins could hamper infection by this bacterial pathogen.

Mice fed a diet high in fat, cholesterol and calories, akin to the Western diet, had higher measures of blood lipids associated with elevated levels of inflammation, a new study finds.

A new study has revealed the death rate of babies in ancient societies is not a reflection of poor healthcare, disease and other factors, but instead is an indication of the number of babies born in that era.

Researchers report that severe COVID-19 patients have alterations in their microcirculation associated with the degree of severity of the disease. The results suggest that there is significant endothelial impairment.

Researchers have developed a technique for assembling optoelectrodes that looks to offer the best of silicon-based electrodes and polymer-based electrodes. The scientists demonstrated it is possible to efficiently create a semiflexible light-emitting electrode by removing the stiff silicon material from underneath the tip of the probe. The resulting device can study deep brain tissues with high resolution to record signals from individual nerve cells and stimulate small groups of neurons with state-of-the-art techniques such as optical waveguides.

A new study has shown that the airborne transmission of COVID-19 is highly random and suggests that the two-metre rule was a number chosen from a risk 'continuum', rather than any concrete measurement of safety.

A cellular study of telaprevir shows that the antiviral blocks the function of essential proteins in bacteria, revealing opportunity to repurpose drug to use alongside antibiotics.
