New therapies for managing aging could emerge from research into a new gene, which scientists have identified as a key driver of degeneration.

A machine learning algorithm running on a smartwatch demonstrated the ability to detect sudden loss of pulse with high specificity (99.99%) and moderate sensitivity (67.23%), according to a study led by Google Research. Designed to identify cardiac arrest events, the system can automatically place an emergency call when it senses an event has occurred, even if the user is unresponsive.

The programmable proteins are compact, modular, and can be directed to modify DNA in human cells.

Our organs age at different rates, and a blood test determining how much they’ve each aged could predict the risk of conditions like lung cancer and heart disease decades later, finds a new study led by University College London (UCL) researchers.

ALS, or amyotrophic lateral sclerosis, can sometimes be difficult to diagnose or to predict how quickly the disease is likely to progress. A new study helps determine which blood tests are best at identifying and monitoring ALS. The study is published in the online issue of Neurology.

UCLA scientists have identified a potential new strategy for treating glioblastoma, the deadliest form of brain cancer, by reprogramming aggressive cancer cells into harmless ones.
