'Label-free' imaging tool tracks nanotubes in cells, blood for biomedical research

Posted: 05 Dec 2011 02:02 PM PST

Researchers have demonstrated a new imaging tool for tracking structures called carbon nanotubes in living cells and the bloodstream, which could aid efforts to perfect their use in biomedical research and clinical medicine.

Lessons learned from yeast about human leukemia: The power of basic model organisms in human health

Posted: 05 Dec 2011 01:59 PM PST

The trifecta of biological proof is to take a discovery made in a simple model organism like baker's yeast and track down its analogs or homologs in "higher" creatures right up the complexity scale to people, in this case, from yeast to fruit flies to humans. In a pair of related studies, scientists have hit such a trifecta, closing a circle of inquiry that they opened over a decade ago.

Acquired traits can be inherited via small RNAs

Researchers have found the first direct evidence that an acquired trait can be inherited without any DNA involvement. The findings suggest that Lamarck, whose theory of evolution was eclipsed by Darwin's, may not have been entirely wrong.
