A study found that early-life epigenetic changes and gut microbiome development are closely linked and may shape the risk of ASD and ADHD. Some gut bacteria appeared to offer protective effects against these conditions. From the moment a baby is born, trillions of microbes begin colonizing the gut while molecular “switches” in the body help [...]

A high-altitude survival gene may point to a new, naturally driven way to repair nerve damage. A genetic adaptation that helps animals thrive in extreme mountain environments may also reveal a new way to repair the human nervous system. Researchers have identified a mutation linked to life at high altitudes that appears to protect and [...]

Endurance improvements from exercise depend on sustained activation of specific brain neurons after workouts. Exercise does more than build stronger muscles. It also reshapes activity in the brain. In a study published in the Cell Press journal Neuron, scientists report that the long-term boost in endurance from repeated workouts, such as being able to run [...]

An artificial lung system sustained a patient for 48 hours without lungs, enabling a life-saving double transplant and highlighting the need for earlier intervention in severe ARDS. People cannot survive without lungs. Yet one of Ankit Bharat’s patients did so for two full days. In a study published in the Cell Press journal Med, surgeons [...]
