The widely-used anticoagulant heparin can have potentially fatal side effects, so researchers have developed a new DNA-based drug to target blood clots.

The ability to utilize a single alternative food source is all it takes for diarrhoea causing Salmonella bacteria to bloom when a gut is already colonized by a closely related strain. This coexistence enables the exchange of antibiotic resistance.

It has been suspected for some time that viral infections contribute to the genesis and development of neurodegenerative diseases. Laboratory studies now suggest a mechanism that does not require infection by external pathogens.

New research has categorized soil bacteria into specialists or generalists, giving greater insight into how they are affected by global changes such as habitat destruction and climate change.

A new study shows that intermittent fasting and calorie restriction change the microbiome diversity in the gut, which could impact other functions in the body.

The Bronze Age peoples of the Caucasus feasted on communal stews made from deer, sheep, goats and cows, a new study has found. The analysis stems from preserved samples of metal cooking cauldrons that still harbored the ancient animal proteins.

The largest ever study of the genetics of the brain – encompassing some 36,000 brain scans – has identified more than 4,000 genetic variants linked to brain structure.

Most of us who’ve reached middle age have noticed a slowing in memory and cognition, but scientists don’t have a clear picture of the molecular changes that take place in the brain to cause it, until now.

Epilepsy in infants ranges in severity and can leave caregivers with questions about their child’s health. While genetic testing to help determine the cause of epilepsy is possible, comprehensive testing does not always happen routinely.

A large-scale international collaboration has identified new genes associated with breast cancer that could eventually be included in tests to identify women at increased risk of the disease.
