mernilio writes"According to UPI: 'A Massachusetts school district superintendent said a memo banning sixth graders from carrying pencils was written without district approval. North Brookfield School District interim Superintendent Gordon Noseworthy said Wendy Scott, one of two sixth-grade teachers at North Brookfield Elementary School, did not get approval from administrators before sending the memo to all sixth-grade parents, the Worcester Telegram & Gazette reported Thursday. The memo said students would no longer be allowed to bring writing implements to school. It said pencils would be provided for students in class and any students caught with pencils or pens after Nov. 15 would face disciplinary action for having materials 'to build weapons.'"

New Sleep Cycle Discovery Explains Why Fatty Diets During Pregnancy Make Kids Obese

ScienceDaily (Nov. 23, 2010) — The link between sleeping and obesity is drawn tighter as a new research published online in the FASEB Journalstudy shows that what your mother ate when she was pregnant may make you obese or overweight by altering the function of genes (epigenetic changes) that regulate circadian rhythm. In the report, pregnant primate females consuming a high-fat diet altered the function of fetal genes that regulate circadian rhythm (including appetite and food intake) during development. The offspring also had non-alcoholic fatty liver disease.

How Sunlight Shapes Daily Rhythms

ScienceDaily (Nov. 23, 2010) — Fresh insight into how biological clocks adjust to having less sunlight in the winter could help us better understand the impact of jet lag and shift work.

Spine Implant Helps Paralyzed People Exercise

An anonymous reader writes "British engineers have created the first muscle-stimulating microchip small enough that several can be implanted in a person's spinal canal. In addition to providing enough stimulation to, say, let users pedal a stationary bicycle, they could also be used for things like stimulating bladder muscles to help overcome incontinence. Their breakthrough is that the devices package everything into one tiny unit. Lasers cut tiny electrodes from platinum foil, which are then folded into a 3D shape that looks like the pages of a book. These pages, in turn, wrap around the nerve roots."

High Alpha-Carotene Levels Associated With Longer Life

Velcroman1 writes"This again: scientists at Oxford University claim canines are smarter than felines. And the reason, according to the researchers, is that dogs are more social animals and therefore have bigger brains than the more solitary-inclined cats. The study, published in the Proceedings of the National Academy of Sciences, charted the evolutionary history of various mammals' brains over 60 million years and found a link between the size of an animal's brain in relation to its body and how socially active it was."

Pumpkin Pie increases Male Sex Drive

Dr. Alan Hirsch, Director of Chicago's Smell and Taste Treatment and Research Center, says the key to a man's heart, and other parts, is pumpkin pie. Out of the 40 odors tested in Hirsch's study, a mixture of lavender and pumpkin pie got the biggest rise out of men ages 18 to 64. That particular fragrance was found to increase penile blood flow by an average of 40%. "Maybe the odors acted to reduce anxiety. By reducing anxiety, it acted to remove inhibitions," said Hirsch.

Should Airplanes Look Like Birds?

ScienceDaily (Nov. 21, 2010) — Airplanes do not look much like birds -- unless you were to imagine a really weird bird or a very strange plane -- but should they? This question is exactly what a pair of engineers in California and South Africa inadvertently answered recently when they set about re-thinking the ubiquitous tube-and-wings aircraft architecture from scratch in order to make airplanes more fuel efficient.
