Key Mental Abilities Can Actually Improve During Aging

People who work night shifts are at increased risk of developing an irregular and often abnormally fast heart rhythm called atrial fibrillation (AF), according to research published in the European Heart Journal.

According to a recent study from Washington University, people who have had mild illness develop antibody-producing cells that can last a lifetime.

Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all the while.

Studies suggest that omega-3 fatty acids can provide many health benefits, findings indicate that they may help to reduce inflammation, decrease blood triglycerides, and they may even help to reduce the risk of dementia.

A gene called Npas4, already known to play a key role in balancing excitatory and inhibitory inputs in brain cells, appears to also be a master timekeeper for the brain's circadian clock, new research led by UT Southwestern scientists suggests. The finding, published online today in Neuron, broadens understanding of the circadian clock's molecular mechanisms, which could eventually lead to new treatments for managing challenges such as jet lag, shift work, and sleep disorders.
