Scientists uncover for the first time how the body’s energy makers are made. An international team of researchers report an insight into the molecular mechanism of membrane-tethered protein synthesis in mitochondria. This is a fundamental new understanding of how the human mitoribosome functions and could explain how it is affected by mutations and deregulation leading […]

Scientists have used a technique to grow bile duct organoids – often referred to as ‘mini-organs’ – in the lab and shown that these can be used to repair damaged human livers. This is the first time that the technique has been used on human organs. Source: Lab-grown 'mini-bile ducts' used to repair human livers […]

The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. Researchers have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals.

In a world first genetic study, researchers found that that long-term, heavy coffee consumption – six or more cups a day – can increase the amount of lipids (fats) in your blood to significantly heighten your risk of cardiovascular disease (CVD).

In structural biology, some molecules are so unusual they can only be captured with a unique set of tools. That’s precisely how a team defined how antibodies can recognize a compound called phosphohistidine — a highly unstable molecule that has been found to play a central role in some forms of cancer. Source: Never-before-seen antibody […]

Researchers who focus on fat know that some adipose tissue is more prone to inflammation-related comorbidities than others, but the reasons why are not well understood. Thanks to a new analytical technique, scientists are getting a clearer view of the microenvironments found within adipose tissue associated with obesity. This advance may illuminate why some adipose […]

A new system can detect the chemical and microbial content of an air sample with even greater sensitivity than a dog’s nose. Researchers coupled this to a machine-learning process that can identify the distinctive characteristics of the disease-bearing samples.
