…ll selection of different materials: bricks, mortar, iron, glass, and wood. Arranged in different ways, these few materials can yield a huge variety of structures. We encountered functional groups and the SPHONC in Chapter 3. These components form the four categories of molecules of life.

Unicorns and Brainbows
orite, shown below: A cerebellar flocculus, a lobe in the cerebellum, from the original Brainbow paper (Source) Since its original description, researchers have used the Brainbow concept extensively — it has been cited 361 times, according to the Web of Science – and extended it into zebrafish and fruit flies, both species that researchers frequently use in experiments to trace gene expression and how animals develop.

Friday Roundup: Arsenic in juice, self-medicating chimps, science tattoos, Guinness Record-setting science cheerleaders, and more!
…wering the standard it’s set for how much arsenic exposure is OK in apple and other juices. Cutoffs are usually set in what are known as “parts per billion” (ppb). That means what you think: if the cutoff is 3 ppb, that means, for example, three drops in a billion drops. Right now, the cutoff for arsenic in drinking water is 10 ppb, and consumer groups are asking the EPA to drop that to 3 ppb. Deborah Blum has addressed the fact…

After Newtown missteps, journalists get guidelines
…almost twice as likely to say that they don’t want to live or work near a person with mental illness if they read an article about a person with mental illness involved in a mass shooting, according to a study published March 20 in the American Journal of Psychiatry.
