Gene therapy cuts levels of Alzheimer's protein

A molecule that naturally degrades a protein linked to Alzheimer’s disease appears to reduce the levels of that protein by nearly 50 percent when delivered by gene therapy, researchers at the Salk Institute and UC San Diego have found in collaboration with researchers at the University of Kentucky. The findings appear in the March 15 issue of the Journal of Neuroscience.

People from distant lands have strikingly similar genetic traits

Scientists have long recognized that, despite physical differences, all human populations are genetically similar to one another. But a new study in the journal Science concludes that populations from different parts of the world share even more genetic similarities than had previously been assumed. At the same time, researchers found that tiny differences in DNA can provide enough information to identify the geographic ancestry of individual men and women.
