Scientists Unravel Mystery of Aging: Gene Length Is the Decisive Factor

Leave a Comment / Science / By

Scientists think they have cracked the secret of aging. Major genetic analysis of people, rodents and fish has revealed that the length of their DNA is directly related to their biological age. Shorter genes were associated with shorter lifespans, while longer genes were linked to better health and longevity. Scientists believe that if they can …

New space observatory helps solve mystery involving huge black holes

Leave a Comment / Science / By

Most galaxies are built around huge black holes. While many of them are relatively docile, like the one at the center of our Milky Way, some are ferocious – gobbling up surrounding material and releasing huge jets of extremely bright high-energy particles far into space. Using data from the recently deployed Imaging X-ray Polarimetry Explorer …
