Study sheds light on stem cell role in regenerating fingers, toes

Tissue-specific adult stem cells are responsible for the ability of mammals to re-grow the tips of fingers or toes lost to trauma or surgery, say researchers at the Stanford University School of Medicine. The finding discredits a popular theory that holds that previously specialized cells regress, or dedifferentiate, in response to injury to form a …

Cheaper and more efficient water desalination

In the new study, Elimelech and William Phillip, now at the University of Notre Dame, demonstrate that reverse osmosis requires a minimum amount of energy that cannot be overcome, and that current technology is already starting to approach that limit. Instead of higher water flux membranes, Elimelech and Phillip suggest that the real gains in …
