While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

Neurogeneticists have discovered a novel genetic mutation and associated buildup of toxic proteins in the brain -- a type of buildup distinct from amyloid or tau, proteins that have long been the ...

Researchers have refined a powerful DNA sequencing tool that can uncover hidden mutations that occur naturally in our bodies as we age. In the largest study to date, they have used the tool to provide ...

Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism by which brain cells die. The findings raise the possibility that similar ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

Deafness, the most common sensorineural hearing loss at all stages of life, occurs either independently or as part of ...

The root causes of most forms of Alzheimer's disease largely remain a mystery. Now, researchers have revealed a new piece of the puzzle. Neurogeneticists at the University of Florida led by Lien ...

A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

Meet the luckiest people on Earth — individuals carrying a rare genetic mutation that prevents wrinkles from forming even as they age well into their 80s. These genetic lottery winners have provided ...
