Using an animal model of multiple sclerosis (MS), researchers at the National Institutes of Health (NIH) have created a four-dimensional brain map that reveals how lesions similar to those seen in human MS form. These findings, published in Science, provide a window into the early disease state and could help identify potential targets for MS treatments and brain tissue repair.

Red blood cells carry oxygen from the lungs to every other organ, and blood-forming stem cells must make about 200 billion new red blood cells each day to keep the oxygen flowing.

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.
