Study on mice offers clues in quest to reverse effects of aging

It’s not the Fountain of Youth just yet, but a new study led by researchers from Harvard and MIT might offer important clues in the quest to reverse the effects of aging.As people age, their blood vessels lose the capacity to deliver oxygen and nutrients to muscles, resulting in loss of endurance, said David Sinclair, a professor of genetics at Harvard Medical School and a senior author of the study.

Shielding the Human Genome: Mitigating the Threat of Space Radiation

For decades, NASA and others have studied the radiation problem and searched for solutions. Left unchecked, sustained exposure to space radiation will make long-duration manned missions beyond Earth’s ionosphere dangerous and, in some worst-case scenarios, lead to disease and death. It was this challenge that led NASA in 2016 to describe exposure to space radiation as the most dangerous aspect of travel to Mars.

Scientists Can Reverse DNA Aging in Mice

Dr. David Sinclair, from Harvard Medical School, and his colleagues reveal their new findings in the latest issue of Science. They focused on an intriguing compound with anti-aging properties called NAD+, short for nicotinamide adenine dinucleotide. It's been known that younger mice had more of it than older mice and back in 2013, the researchers found that when they boosted the NAD+ levels in older mice, they looked, biologically, like much younger animals.
