    …ory. While eating more healthy foods is always a good idea, no food has curative effects all on its own. Other aspects of blueberry nutrition includes it as a source of sugar. One cup (148 g) of blueberries contains about 15 g of sugar and 4 g of fiber, a single gram of protein, and half a gram of fat. If you are counting carbs, this cup has 21 g of them. That one cup of blueberries averages about 85 calories, which is approximately the same…

    …e X Extra: A triglyceride can have up to three different fatty acids attached to it.

  • Walnuts, willful murder, & World Book Night

    …it’s the dose that makes the poison. It can take a black walnut tree 25 years to introduce enough juglone into the surrounding soil to cause “walnut wilt” or death in sensitive plants –  but less than 10 years can do the trick in some cases. This wide window of lethality results from many factors, such as rate of tree growth, soil and drainage conditions, and diversity of soil microorganisms. Plants sensitive to juglone i…

  • Motherhood Defined: It is in the heart of the beholder

    “Motherhood”: Sculpture at the Catacumba Park, Rio de Janeiro, Brazil Motherhood.  It can mean many things, and our own definition of it is largely defined by our individual experiences.  To one person, motherhood might simply mean the act of raising children; to another, motherhood might be what defines them.   It is not uncommon to generalize the concept of “motherhood” and lump everyone who upholds a singl…

  • 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…

    …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…
