Don't Use Your Hands? You May Not Be Good at Math

So that explains it.  I never used my hands to gesture during a math lesson.

 A new study says that kids who do gain a deep understanding of the problems they are taught. Now I understand why I got 400 on my math SAT.
Previous studies have found that gestures can help children learn, according to newswise.com. "This study in particular was designed to answer whether abstract gesture can support generalization beyond a particular problem and whether abstract gesture is a more effective teaching tool than concrete action," the Web site notes.
“We found that acting gave children a relatively shallow understanding of a novel math concept, whereas gesturing led to deeper and more flexible learning,” explained the study’s lead author, Miriam A. Novack, a PhD student in psychology at the site.
Researchers randomly assigned 90 children to conditions in which they learned using different kinds of physical interaction with the material. In one group, children picked up magnetic number tiles and put them in the proper place in the formula, newswise.com reports. Another group mimicked that action without actually touching the tiles, and a third group was taught to use abstract gestures with their hands to solve the equations. 
Children in all three groups learned the problems they had been taught during the lesson. But only children who gestured during the lesson were successful on the generalization problems.
“Abstract gesture was most effective in encouraging learners to generalize the knowledge they had gained during instruction, action least effective, and concrete gesture somewhere in between,” said senior author Susan Goldin-Meadow, the Beardsley Ruml Distinguished Service Professor in Psychology. “Our findings provide the first evidence that gesture not only supports learning a task at hand but, more importantly, leads to generalization beyond the task. Children appear to learn underlying principles from their actions only insofar as those actions can be interpreted symbolically.”
I guess what she's saying is that I just didn't get the hang of the hands thing.

Take Herbal Supplements? Even Green Tea Extract Can Lead to Liver Damage

Take herbal supplements? You might want to listen up. A new study is warning that new information is showing that some supplements may damage the liver, along with over the counter drugs and even those prescribed by physicians, according to newswise.com. The rate of drug-induced liver injury (DILI), a rare adverse drug reaction which is challenging to diagnose -- and which can lead to jaundice, liver failure and even death -- is increasing more and more.  Experts put it down to the overwhelming use of herbal supplements and other drugs in the last 10 years.  “A lot of consumers have a preconceived notion that if it’s a natural product, it must be safe. But that is not necessarily the case,” the Web site quotes Herbert Bonkovsky, MD, FACG, co-author of the guidelines. “Most of these products are not well-regulated and have very little oversight. Traces of heavy metals and prescription drugs have even been found in some herbal and dietary supplements. We encourage patients to

Social Media Replacing Human Contact? Nah

I used to think my son only talked to his "girlfriend" (did I mention he'll be 12 in June?) in school.  Then I happened to walk by his computer and saw her on his screen.  They Skype.  About three hours a day.  Then I got it.  It's real.  Kids mostly communicate electronically these days. But Joe McKendrick at smartplanet.com believes there are reasons social media won't completely replace face-to-face interactions.  For one, there's less distraction.  If you're sitting at your computer, you're scanning for emails or googling or watching the news, in addition to talking to someone.  When you're actually with someone, it's harder to do this -- though, Joe, are you living on Mars? Have you never seen a teen texting at the table, while talking to you, or God forbid, driving? Most of McKendrick's points have to do with the office, and meeting in person to do business rather than connecting online.  I have to admit here, it makes sense.  He

Don't Wash Your Chicken and Other Food Safety Myths

I remember when I first heard this.  Don't wash your chicken , before you cook it?  I ignored it.  But over time, I began to realize it's true.  Washing it spreads deadly (or at least sick-making) bacteria.  Really. “You should assume that if you have chicken, you have either Salmonella or Campylobacter bacteria on it, if not both,”Dr. Jennifer Quinlan, an associate professor at Drexel University, told newswise.com.  These two bacteria, she noted, are the leading causes of food-borne illness. “If you wash it, you’re more likely to spray bacteria all over the kitchen and yourself," she said. And the rinse water you've been using? It's not hot enough to kill bacteria anyway. Washing raw poultry was a common unsafe practice in all the groups she studied for a documentary on safe cooking conditions, with some minor cultural differences in the method of washing. People are very attached to the idea of washing raw poultry, she told newswise.com. “Some think they’re
