Genetic Mutations May Be Behind Epigenetic Clock of Aging

Researchers at University of California San Diego School of Medicine have published results that shed new light on an old question: what causes aging at the molecular level? Their findings, published in Nature Aging, describe a never-before-seen link between the two most accepted explanations: random genetic mutations and predictable epigenetic modifications.

Deep Sea Foraminifera Species Unveil Secrets of Life in Extreme Environments

Most life on Earth relies on the sun's energy for survival, but what about organisms in the deep sea that live beyond the reach of its rays? A new study led by Woods Hole Oceanographic Institution (WHOI), published in The ISME Journal, sheds light on how a species of foraminifera, single-celled organisms found in almost all marine habitats, thrives in a dark, oxygen-free environment.
