Regardless of high or low overall scores on an IQ test, children with dyslexia show similar patterns of brain activity, according to researchers supported by the National Institutes of Health. The results call into question the discrepancy model — the practice of classifying a child as dyslexic on the basis of a lag between reading ability and overall IQ scores.
A study published this week in the Journal of the American Medical Association suggests that even moderate alcohol consumption — as little as one-half to one drink per day — increases a woman’s risk of breast cancer by about 15% [1]. Daily consumption of two or more drinks per day (where a “drink” contains about 14 grams of pure alcohol, and results are independent of the type of drink consumed) increases breast cancer risk by 50%. These results suggest a much stronger effect of low to moderate alcohol consumption on lifetime breast cancer risk than previous studies [2-4] have done.
National Institutes of Health (NIH)-funded scientists have corrected sickle cell disease in adult laboratory mice by activating production of a special blood component normally produced before, but not after, birth.
Sickle cell disease is a recessive genetic disorder caused by a single base mutation in the gene for hemoglobin, beta locus (HBB). Hemoglobin is responsible for transporting oxygen throughout the body. People living with sickle cell disease have two copies of an altered gene that produces sickle hemoglobin instead of normal adult hemoglobin. Sickle hemoglobin changes shape after releasing its oxygen, causing the red blood cell to become stiff, misshapen and sticky, and slowing blood flow to tissues. This process damages organs and causes pain.
In an effort to promote public health awareness, the U.S. Centers for Disease Control and Prevention (CDC) has outlined preparation basics for the zombie apocalypse [1].
Yes, you read that right: zombie apocalypse.
As it turns out, preparing for the zombie apocalypse is similar to preparing for any other disaster: stock up on food, water and medications; have tools and supplies on hand; have items for sanitation and hygiene; etc. The CDC outlines emergency preparedness elsewhere on their website, but apparently no one really wants to read about preparing for a tornado, flood or winter weather. What people do want to read about is the zombie apocalypse. Thus, running with the idea that how you prepare is more important that what you prepare for, CDC went with a tongue-in-cheek, partially no-nonsense discussion of the undead and what happens when they attack.
