  • Friday Roundup: Arsenic in juice, self-medicating chimps, science tattoos, Guinness Record-setting science cheerleaders, and more!

    …et 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 that arsenic is present in food, water, and soil and that different forms of it have different effects. As always, it&…

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

    …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? Fat is a necessary nutrient for everything from our nervous systems to our circulatory health. It also, under appropriate conditions, is an excellent way to store up…

  • 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…

  • We gotta watch out for feminine role models wearing pink

    Beware blonde, feminine role models wearing pink.(Source) Today’s guest post comes to us courtesy of Sara Callori. She is a physics Ph.D. candidate at Stony Brook University in Long Island, NY. In the lab, Sara loves working with x-rays and even has a Bragg diffraction tattoo. She would eventually like to focus on science teaching and outreach because she loves to get people to stop being intimidated when they think of physics….

  • #DispatchesDNLee: Handling lady-business in the field

    …t a yelp. I tried to hold my scraped leg under the hot water to clean the wound. But it stung like the devil. I cried, much like I did as little girl. I looked down at my scarred legs and immediately recollected the summer of 1981. I was such a tomboy, playing in the yard and in the streets with my boy cousins, and clumsy, so clumsy. My legs and arms were covered in bandages like tattoos. This obviously frustrated my bio-dad to no end. I vividly…

  • Friday Roundup: 2011 top science lists, radium laced condoms, and the clitoris

    A Double X Science grandma showed us this picture. We thought it was the most ridiculously cute thing we’d seen all year. As 2011 draws to a close, media outlets and science bloggers have busily collated their top-10 (or 12 or 20) lists of science-related cool/interesting/freaky/fantastic stuff this year. Here’s a selection that should keep you busy for about the first half of 2012: Smithsonian’s list , including Fran…

  • 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…

  • Is the bar high enough for screening breast ultrasounds for breast cancer?

    …nt movement and legislation to inform women that they have dense breasts. 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. The study showed a statistically significant increase in breast cancer detection when ultrasound was used with mammography. Approval of a device of this nat…

  • 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…

    …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. 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…
