…e X Extra: A triglyceride can have up to three different fatty acids attached to it. Canola oil, for example, consists primarily of oleic acid, linoleic acid, and linolenic acid, all of which are unsaturated fatty acids with 18 carbons in their chains. Why do we take in fat anyway?

A Few Modern Physicists
…tion other than it allows me to choose a small group of women to highlight within a parameter set. These women are listed in no particular order. Vera E. Kistiakowsky spent much of her career as a professor at MIT. Born in 1928, she received her A.B. from Mt. Holyoke College in 1948 and her Ph.D. from the University of California – Berkeley in 1952, both degrees in chemistry. Her chosen career stemmed from advice from her father to support her…

Depressing genes
…ch experience — yet it was obvious he didn’t have the knack for it. This student’s dogged pursuit of a mental health career made me wonder what kind of emotional turmoil he experienced which would make him think, at age 19, that psychiatry was the only vocation worth working towards.

Unicorns and Brainbows
Brainbow is a mouse with a rainbow brain. By Jeffrey Perkel A couple weeks ago I wrote about the beautiful world right under our noses, a world visible only under the microscope. The cover image for that post was this picture, a “‘Brainbow’ transgenic mouse hippocampus,” which placed 18th in the 2008 Nikon Small World Photomicroscopy contest. Brainbow technology also won the 2007 Olympus Bioscapes contest, with this be…
