New research by Nobel Prize winning UCSF researcher, Elizabeth Blackburn, provides a possible mechanism by which exercise protects against stress-related chromosome aging.
The general idea is that by doing a series of basic and repetitive tasks, which get harder over time, you’re actually changing your brain structure. Over time, the manufacturers claim, you can train an old brain to behave like a new one. But many scientists who study aging are skeptical.
You've probably heard about some of the breakthroughs in personal genome sequencing, where companies take a look at your DNA and send back your risk profile. But there's a flip side to all this genetic research that doesn't have to do with risk: personalized medicine.
As a result of the QUEST story, my pregnancy became more of a public event than I expected it to be. Naturally, after the boys were born, there were several inquiries as to our well-being. Here’s what happened:
Researchers call stem cell technology a "revolution" in medicine, along the lines of the development of antibiotics in the 1940s, or the manufacturing of insulin and other therapies from recombinant DNA breakthroughs.
Some 30 researchers from the University of California-San Francisco and the Gladstone Institute of Virology and Immunology have come together to investigate why HIV-positive patients, who are now living longer lives thanks to anti-retroviral drugs, seem to be aging faster than their uninfected peers.
Being a neurologist in the era of fMRI scanners must feel like being a kid in a candy shop. What's going in there while we're, say, shopping? How about reading? Watching campaign ads? Now that we have a way to take real-time images of the brain at work, the scientific possibilities are endless. On the […]
There is a lot we don't know about our DNA and how it works. While there seems to be news every week about genetics, scientists are still in the early stages of finding out what effect our genes have on us (check out this post from another QUEST blogger, Dr. Barry Starr). That's what the […]
