Size matters: How body size shapes dogs' aging patterns

Smaller dogs may live twice as long life as their larger counterparts. But does this size difference also impact how dogs age in terms of behavior and cognitive abilities? Based on the data of 15,000 dogs, researchers from ...

Scientists unlock biological secrets of the aging process

How we grow old gracefully—and whether we can do anything to slow down the process—has long been a fascination of humanity. However, despite continued research the answer to how we can successfully combat aging still ...

How seeing corpses reduces the lifespan of flies

Researchers led by Christi Gendron at the University of Michigan have found the link between death perception and accelerated aging in flies. Their new study, published June 13 in the open access journal PLOS Biology shows ...

New study takes a high-level look at Nazca boobies' breeding

Nazca boobies can live to 28 years of age, but in their late teens, their ability to raise chicks declines substantially. Why their breeding drops in old age has plagued Wake Forest University Professor of Biology David Anderson ...

Scientists slow aging by engineering longevity in cells

Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct ...
