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

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 …

The Y chromosome slowly disappears.  A new sex gene could be the future of men

The Y chromosome slowly disappears. A new sex gene could be the future of men

The sex of human babies and other mammals is determined by a male-determining gene on the Y chromosome. But the human Y chromosome degenerates and could die out in a few million years, leading to our extinction unless we develop a new sex gene. . The good news is that two rodent branches have already …

CRISPR tools found in thousands of viruses could boost gene editing

Phages (seen here attacking a bacterial cell) could use CRISPR-Cas systems to compete with each other – or to manipulate gene activity in their hosts.Credit: Biophoto Associates/SPL A systematic scan of viral genomes has revealed a wealth of potential CRISPR-based genome editing tools. CRISPR-Cas systems are common in the microbial world of bacteria and archaea, …
