Scientists have identified a mechanism by which the bacterium Pseudomonas aeruginosa can evade antibiotics by surrounding its cells with a self-made protective casing.

After reconstructing the ancient forms of two cellular proteins, scientists have uncovered the earliest known instance of a complex form of protein regulation.

To help answer one of the great existential questions - how did life begin? - a new study combines biological and cosmological models.

Researchers have succeeded in crystallizing and mapping a novel conformation of LeuT, a bacterial protein that belongs to the same family of proteins as the brain's so-called neurotransmitter transporters. The discovery could help design better drugs for conditions including ADHD, depression and epilepsy.

An international team of scientists has launched a comprehensive overview of all proteins expressed in the brain. The open-access database offers medical researchers an unprecedented resource to deepen their understanding of neurobiology and develop new, more effective therapies and diagnostics targeting psychiatric and neurological diseases.

Several studies in recent years have reported that low-calorie sweeteners in foods and beverages disrupt the human metabolism, promoting the development of diabetes and obesity. A new study by Yale researchers may help reconcile these conflicting findings.

Eating more protein from plant or dairy sources while reducing red meat consumption could help people live longer, according to two preliminary studies.

Researchers have developed a new technology called μMap that identifies proteins' nearest neighbors on cell surfaces. This approach could be used to target proteins involved in cancer and guide the development of new cancer drugs.

Researchers have pinpointed an enzyme with a key role in the mechanisms involved in controlling cell protein traffic.

Researchers at Western University are studying a molecule found in sweet oranges and tangerines called nobiletin, which they have shown to drastically reduce obesity in mice and reverse its negative side-effects.
