  • Biology Explainer: The big 4 building blocks of life–carbohydrates, fats, proteins, and nucleic acids

    …molecules themselves break down into a surprisingly small number of building blocks. The proteins that make up all of the living things on this planet and ensure their appropriate structure and smooth function consist of only 20 different kinds of building blocks. Nucleic acids, specifically DNA, are even more basic: only four different kinds of molecules provide the materials to build the countless different genetic codes that translate into all…

  • Two Science Online 2012 sessions for your consideration

    Tomorrow, I head for North Carolina to attend Science Online 2012.

This year, I’m attending as a participant and as a moderator of two sessions. The first session, on Thursday afternoon, is with  Deborah Blum , and we’ll be leading a discussion about how and when to include basic science in health and me…

  • 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…

  • No gene is an island: What do scientists mean when they talk about environment and genes?

    Nope. This island does not represent your genes. (Source) When you read news stories about what affects a developing human in the womb or how cancer or obesity arises, you probably also see references to genes and environment. Some articles may focus on genes versus environment, or mention that something is “mostly” genetic or that the “environment” contributes to a disorder or trait in some way. What some people…

  • McConnell and mental illness

    …y unbalanced” because she was hospitalized “for 42 days” in the 1990s for a “mental breakdown” and because she’s talked about having depression. Had Judd been hospitalized for 42 days 15 or 20 years ago for a brain tumor or a heart condition, no one would go near those parts of her history as a way to try to smear her. But mental illness–again–is an open target, a free-for-all for anyone who wants t…

  • Double Xpressions: Jennifer Canale, the self-proclaimed "Flamboyant Scientist"

    …Girl Scouts, I was sent to dance school (but, much to my amazement, I enjoyed that until I was 17).  My parents started giving in around 3rdgrade, and I got the panda bear-shaped calculator I wanted, as well as the robot toy 2XL featuring the 8-track tape. My mom would beg me to watch Little House On the Prairie, but I preferred Star Trek (the original Kirk version), Lost in Space (Danger Will Robinson), and Land of the Lost. Of course this was…
