Spermidine found to increase lifespans of fruit flies, worms

(Newser) - The fountain of youth may be filled with grapefruit and human sperm, according to Austrian researchers. The scientists found that spermidine, a chemical compound abundant in both sperm and grapefruit, increased longevity by around a third in fruit flies and worms when it was added to their diet. Human immune...

New discovery on engineered liver genes could slow aging

(Newser) - US researchers believe they have found a way to turn back the clock on the processes which make organs age. Scientists engineered genetic alterations to make the livers of older mice function like younger mice, the BBC reports. The discovery may lead to new treatments for Alzheimer's and other diseases...

Discovery reveals what makes wine taste good and why it's good for you

(Newser) - Grapevines have extra genes that are responsible for making wine taste and smell so good, a new study finds. A team of researchers from France and Italy (where else?) mapped a pinot noir-related grapevine's genome and found it has twice as many genes linked to resin and oil—which give...
