    …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?

  • After Newtown missteps, journalists get guidelines

    Protip: Don’t diagnose based on speculation. by Jessica Wright                Attention journalists: If you’ve been calling people “nuts” or “deranged” in your stories, the Associated Press is recommending that it’s time you stopped. This guideline — along with the common-sense assertion that writers shouldn’t diagnose individuals with a mental illness based entirely on speculation — is part of a new recommendation added to the AP styleboo…

  • Double Xpression: Liz Neeley, Science Communicator Extraordinaire

    …s code thing.  One day, when I was in the lab, I was wearing this pink, strappy sundress, tied up the back, and these stupid platform sandals that were really tall (clearly not appropriate lab gear).  I was scrubbing out this 100-gallon oyster tank and my advisor happened to walk by and he sees me doing this. I remember freezing – all of the sudden I was afraid he was going to mock me or lecture me, but he just said, “Oh, Liz… Keep on.” My gradu…

    …of us are involved in policing the neighborhoods, some of us build structures, some of us communicate information, some of us deal with food, some of us get rid of waste, etc.  Every cell gets a job (it’s the only example of 100% employment rates!). Now back to the cells in the fertilized egg.  As they start to learn what their specific job will be, the cells within the sphere will start to organize themselves.  After about 5 days after fertil…

  • 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…

Merits and pitfalls of device approval The approval of breast ultrasound hinges on a study of 200 women with dense breast evaluated retrospectively at 13 sites across the United States with mammography and ultrasound.

  • Autism and the DSM-5

    …questions in the context of these criteria. I’ve expanded on a couple of these reports at length elsewhere, as have others with an interest in the subject. The short version is that studies overall indicate that at the least, 10% of people who would currently have an autism diagnosis under the DSM-IV-TR criteria would lose that diagnosis under the DSM-5, and some studies go as high as 55% in their estimates. Even more troubling? The committee’s s…

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. Then there were the two graduate students who both worked incredibly hard and were both prone to obsess about their experiments. Each burned off stress in quit…
