Genetic manipulation cuts nerve damage, boosts life span

A novel genetic manipulation significantly extends the life spans of flies by reducing the amount of wear and tear suffered by nerve cells in adults, according to new work published in Cell Metabolism. The findings support the idea that therapies designed to protect the adult nervous system by curbing the production of damaging free radicals might effectively increase longevity in other animals, including humans, the researchers said.

Greater risk of heart attack associated with Vioxx than Celebrex

In the first epidemiological study designed and executed specifically to determine the heart-attack risk associated with COX-2 inhibitors rofecoxib (Vioxx) and celecoxib (Celebrex), researchers at the University of Pennsylvania School of Medicine found a greater risk of heart attack associated with Vioxx than Celebrex, although neither of the two drugs showed a statistically significant elevated risk of heart attack relative to people who did not use the drugs.
