Mind-body: How mental, physical pain are linked

Maybe it’s because many of us have so much stuff and so many opportunities to satisfy our desires that we crave something more, something deeper, something that would give our lives touch of transcendent meaning.  As a society we’ve come to the point at which more possessions or more fame, or more fortune don’t bring any more happiness. We feel it in our stress levels and know we need something beyond.

Throughout history this yearning for “something more” has been the province of religion, but in the last generation or so, science has entered this domain with impressive results. In fact, if we knew as much about treating cancer as we do about the science of health and happiness we’d be tempted to pronounce the disease cured.

FDA limits amount of acetaminophen in prescription drugs

Manufacturers of prescription drugs containing acetaminophen are being asked to limit the dosage of the drug and add a liver toxicity warning to product labels, the Food and Drug Administration announced Thursday.  This so-called "boxed warning" is the agency's strongest warning for a prescription drug.

Makers of prescription products that include acetaminophen, a popular pain and fever reducer better known under the brand name Tylenol, will be required to limit the amount of the drug to no more than 325 milligrams (mg) per tablet or capsule.  Currently some products contain between 500 mg  to 750 mg per dose.

Writing about anxiety may boost test scores

Writing about anxiety may boost test scores

You probably remember it all too well: clenching your teeth as the teacher handed out the final exam, worrying about what curve-ball problems might appear and how your score would affect your GPA.

It's as if your brain is a computer running too many programs at once, says Sian Beilock, associate professor of psychology at the University of Chicago. Stressing about the consequences of your score uses up valuable thinking and resources in your brain, and can actually make you perform worse when you actually start taking the test.

It turns out that writing about these anxieties right before the test may boost a grade. A new study in the journal Science suggests that high school and college students may significantly benefit from putting their worries on paper before taking an exam.

Subway tests gluten-free sandwiches

Subway is testing a bun made of egg whites, corn starch and tapioca starches for customers with gluten sensitivities at 700 outlets in Dallas and East Texas.  The sandwich chain is also offering a gluten-free brownie for dessert.  The brownie is made of potato starch, cocoa and sugar.

“Gluten-free is something on the radar,”  said Les Winograd, Subway spokesman.  “There are number of people at Subway who are particularly interested in gluten-free items for their own particular digestive needs. It’s not something that’s unusual to us.”

With Subway exploring a wheat-free alternative, is this a sign that major food chains are paying more attention to gluten sensitivities such as celiac disease? FULL POST

Antibiotics speed up recovery from ear infections in young children, studies show

Giving babies and toddlers antibiotics when doctors are certain they have ear infections can help speed up their recovery, supporting current treatment guidelines for children between the ages of 6 months and 23 months.

However, antibiotics do come with significant side effects including diarrhea, rashes, yeast infections and vomiting. Overuse of drugs also contributes to antibiotic resistance, so careful selection of who should take antibiotics is necessary according to 2 studies published Wednesday in the New England Journal of Medicine.

The power of smell in picking sex partners

The power of smell in picking sex partners

Ladies, be honest: When it comes sexual attraction, how important is a guy’s smell? Not just his cologne or deodorant, but his natural scent? At Good in Bed, we believe that a woman should “follow her nose—it always knows.”

Research supports this idea: In two large studies led by Brown University olfactory expert Dr. Rachel Herz, women ranked a man’s scent as the most important feature for determining whether she would be sexually interested in him.

As it turns out, scent may be the main way in which women literally sniff out genetic compatibility with a potential mate. How we smell is an external expression of the genes that make up our immune system.
