New Research Sheds Light on M.O. of Unusual RNA Molecules

Kimm Fesenmaier
A team of researchers led by newly arrived Caltech biologist Mitchell Guttman and Kathrin Plath of UCLA, has figured out how some RNA molecules take advantage of their position within the 3-D structure of genomic material to home in on targets.

Keeping Stem Cells Strong

Katie Neith
A team of researchers led by biologists at Caltech has found that, in mouse models, the molecule microRNA-146a (miR-146a) acts as a critical regulator and protector of blood-forming stem cells during chronic inflammation, suggesting that a deficiency of miR-146a may be one important cause of blood cancers and bone marrow failure.

Fifty Years of Clearing the Skies

Douglas Smith
Los Angeles has had bouts of smog since the turn of the 20th century. Angelenos might now be living in a state of perpetual midnight—assuming we could live here at all—were it not for the work of Caltech professor Arie Jan Haagen-Smit.

Developing Our Sense of Smell

Katie Neith
Biologists at Caltech have found that neural-crest stem cells—multipotent, migratory cells unique to vertebrates that give rise to many structures in the body such as facial bones and smooth muscle—play a key role in building olfactory sensory neurons in the nose.
