If Partner Dozes off, No Problem

1 Talking About Ourselves Is Like Having Sex

Roughly 40 percent of our daily speech is devoted to one primary subject: ourselves. Neuroscientists at Harvard wondered if there was more than mere vanity or self-absorption behind this phenomenon, and conducted a series of tests which indicated that we talk about our own thoughts, feelings and accomplishments because it turns us on. More accurately, MRI scans have revealed that talking about ourselves triggers heightened activity in our brain's mesolimbic dopamine system, the area of the brain that produces the rewarding feeling of satisfaction associated with sex, food, and money. It may be even stronger than money: when offered small cash amounts to discuss other people, volunteers turned down up to 25 percent of the possible income to reveal information about themselves instead.

Lowers Blood Sugar

2 High Fat Diet for Diabetics Defies Convention

A high fat diet, while flouting conventional wisdom that recommends reducing fat intake, lowered blood sugar and improved blood lipids in diabetics found a two-year dietary study at Linkoping U. The study, led by Hans Guldbrand and Fredrik Nystrom, included 61 Type 2 diabetes patients who were separated into two groups. One group followed a low-carb, high fat diet; the other followed a low-fat diet. While both groups averaged a similar weight loss, those in the low carb group experienced a clear drop in blood sugar levels, therefore allowing them to reduce their insulin amounts. And, contrary to predictions, those in the high fat group experienced an increase in HDL or good cholesterol. Those in the low fat group did not experience these health benefits although they did lose weight.

Truvada for High Risk

3 First HIV Prevention Drug Wins over Advisors

Truvada, a drug which is already approved for AIDS treatment, has been recommended for approval by an FDA advisory committee to be used for HIV prevention. On Thursday, the advisory committee voted in favor of using Truvada for pre-exposure prophylaxis (PrEP) for uninfected men who have sex with men, for couples with one uninfected partner, and for people who engage in sexually risky behavior. Truvada, made by Gilead Sciences, Inc., is currently used once daily with other HIV drugs to prevent the HIV virus from replicating in the body.

One Death, Two Injuries

4 Deadly Inflatable Pool Slides Recalled

One death and two injures are blamed on the Banzai in-ground pool water slide sold for $250 between January 2005 and June 2009 at Walmart and Toys R Us. According to the U.S. Consumer Product Safety Commission (CPSC), a 29-year-old mother died after fracturing her neck while going down the inflatable slide which was placed over the concrete edge of a pool. The woman struck her head at the bottom of the partially deflated slide. A 24-year-old man became a quadriplegic after using the slide, and another woman fractured her neck. The pool slide has a blue base, yellow sliding mat, and the words "Banzai Splash" in a circular logo shaped like a wave. Consumers should cut the two safety warning notices out of the slide and take them to Walmart or Toys R Us for a full refund.

Homemade Zip Line Gets Scary

5 Student Fights Flesh Eating Bacteria

Aimee Copeland, 24, is fighting a rare, flesh-eating bacteria called Aeromonas hydrophila. The graduate student suffered a deep cut after falling from a homemade zip line in Georgia. Despite receiving medical care for her wound, Aimee developed necrotizing fasciitis, most likely caused by bacteria at the zip line site. She lost her leg to the disease, and may now lose both hands and her other foot. Aimee is listed in critical condition at the Joseph M. Still Burn Center at Doctors Hospital in Augusta, Ga, reports CBS News. She is alert, but has a breathing tube which makes talking difficult.

Dogs Trained for Brain Scans

6 Scientists Learn How to Read a Dog's Mind

Dogs can be trained to lie still inside an MRI machine long enough to get brain scans, learn researchers from Emory University in Atlanta. Time reports that it took the researchers eight months to train two dogs to stay motionless while wearing earmuffs to block noise inside the MRI machine. Gregory Berns, professor of neuroeconomics at Emory, says that now they can really start to understand what a dog is thinking. Researchers analyzed the brain activity in response to hand signals indicating a dog may or may not receive a treat. They found that the appropriate brain regions lit up in anticipation of a reward. Researchers say this is just the beginning. They hope to get to the bottom of how dogs really think and feel!
