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 …

Autism-linked gene discovered to shape nerve connections – Neuroscience News

Summary: The autism-linked Gabrb3 gene appears to shape the formation of normal and atypical neural connections in the brain. Source: Cornell University A gene linked to autism spectrum disorders plays a critical role in early brain development and may shape the formation of normal and atypical nerve connections in the brain, according to a new …

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, …

Gene-delivering viruses reach the brain in a step towards gene therapy for neurological diseases – Neuroscience News

Summary: Researchers have developed a family of adeno-associated viral (AAV) vectors capable of crossing the blood-brain barrier to deliver gene therapies directly to the brain. Source: Broad institute Gene therapies can treat and even cure some genetic diseases, but it is difficult to deliver the treatments to the parts of the body where they are …

Gene mutation leading to autism found to overstimulate brain cells – Neuroscience News

Summary: A gene associated with autism overstimulates brain cells significantly more in neurons without mutation. Source: Rutgers University Scientists seeking to understand the basic brain mechanisms of autism spectrum disorder have discovered that a genetic mutation known to be associated with the disorder causes brain cells to be overstimulated far greater than that seen in …
