Biological clock able to measure age of most human tissues

Everyone grows older, but scientists don't really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process. Published ...

Scientists turn back the clock on adult stem cells aging

Researchers have shown they can reverse the aging process for human adult stem cells, which are responsible for helping old or damaged tissues regenerate. The findings could lead to medical treatments that may repair a host ...

A gene for brain size only found in humans

About 99 percent of human genes are shared with chimpanzees. Only the small remainder sets us apart. However, we have one important difference: The brain of humans is three times as big as the chimpanzee brain.

Skeletal stem cells regress when tasked with extensive regeneration

Adult mouse skeletal stem cells in the jaw revert to a more developmentally flexible state when called upon to regenerate large portions of bone and tissue, according to a study by researchers at the Stanford University School ...

It takes a heart to make a better lung

Interactions between the developing heart and lungs are essential for proper growth and maturation; however, much is still unknown about the co-development of these critical organs. To provide fresh insight, a team of collaborators ...
