Might it someday make sense to sequence every newborn's genome? Should doctors and parents learn of all the genetic risks a child faces? A new $25 million, 5-year federal research program is exploring these questions.
Synthetic biology now makes it possible to add fluorine atoms just where they are desired on large drug molecules, which could revolutionize medicines based on compounds harvested from living organisms.
A research team has identified a potential new drug lead for Alzheimer's disease: a small molecule that stabilizes the components of retromers, molecular complexes that act like recycling bins in cells.
