Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy。 The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago。 Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly
Scientists at UCLA discovered a surprising reason aging muscles heal more slowly。 In older muscle stem cells, a protein called NDRG1 builds up and acts like a brake, slowing the cells’ ability to jump into repair mode after injury。 But there’s a twist: that same protein helps the cells survive the stresses of aging, allowing them to stick around lo
Researchers have created quantum control techniques that can make a system appear to run backward in time。 By precisely managing quantum measurements, they can reshape the system's arrow of time and even harvest energy from the measurement process itself。 The breakthrough could lead to more powerful quantum computers, quantum batteries, and other a
Could something as simple as vitamin C help support a healthier aging brain。 In a study of more than 2,000 older adults in Japan, researchers found that people with lower vitamin C levels in their blood also tended to have less gray matter and weaker connections in a key brain network involved in memory, attention, and other cognitive functions
Aging may trigger the appearance of specialized stem cells that supercharge the body's ability to create new belly fat。 The discovery reveals a potential biological driver of middle-age weight gain and a promising target for future anti-obesity treatments
