What is gluten? Gluten is a protein that is found in certain grains, including wheat, barley and rye and triticale (a cross between wheat and rye). What problems prompt people to avoid gluten? Gluten causes inflammation of the small intestine in people with celiac disease, which is an autoimmune disease diagnosed with a blood test or biopsy; other symptoms include digestive problems, anemia, fatigue, headaches and joint pain. Avoiding gluten is the treatment, though there is no cure.

Dieters used to shun that little bowl of salted and mixed nuts at parties - too fattening, they'd say. But nuts have moved beyond the cocktail crowd. They're an economical source of protein being used in every course of the meal for all kinds of eaters: as flour for the gluten-averse, milk for the lactose-intolerant and even as a snack for people watching their fat intake. Only a few decades ago, many doctors and nutritionists warned that nuts should be eaten on special occasions and even then only sparingly.

Ever wonder why there's no birth control pill for men? For starters, it's a math problem: To stop a woman from getting pregnant, all you have to do is block a single egg each month. But a man produces millions of sperm each day -- about 1,000 every time his heart beats. Blocking them all is a much bigger task. This helps explain why no one has come up with a reversible form of birth control for men since the condom was introduced centuries ago. (The first unambiguous description of the prophylactic's use appears in a 1564 writing called "De Morbo Gallico," which describes a syphilis outbreak in Europe that began in France in the 1490s.)

It's too late to lose that unwanted weight for summer. But if you start now - and aim to shed a modest 2 pounds a week - you could drop as much as 40 pounds in time to ring in 2013. The hardest part, however, might be choosing a new diet. This season's crop of cookbooks includes a whiplash-inducing array of advice. For every book urging you on to eat: More carbs! More protein! More fat! there's another seemingly well-reasoned argument to do the opposite. As if this isn't confusing enough, there's a new bogeyman on the diet scene: gluten.

There's a new weapon in the fight against the flu: Researchers have discovered that a synthetic protein called EP67, commonly used as a helper molecule in vaccines, is highly effective on its own when taken within 24 hours of infection. Vaccines are currently the best weapon we have against the flu. But vaccines target individual strains of the virus, meaning that if public health experts guess incorrectly when they develop that season's flu shot, it will do little good for the population.

This post has been corrected. See note at the bottom for details. Who hasn't heard of mad cow disease? Maybe there are a lot more diseases like that than we recognize -- such as Parkinson's, Alzheimer's and Huntington's -- that are caused by a rogue, mis-folded piece of protein that seeds other bits of protein to mis-fold as well. So argues Stanley Prusiner, a UC San Francisco professor, in a commentary in the journal Science. Prusiner won a Nobel Prize for finding that a class of neurodegenerative diseases (of which mad cow is one)

A calorie is a calorie is a calorie - or is it? Maybe not, a small study has found. Once the pounds are shed, the proportions of carbohydrates, proteins and fats you chow down on may determine whether you keep the weight off - or slowly but surely pack on pounds again. In an intensive, seven-month experiment during which 21 overweight men and women had their diets strictly controlled down to each last morsel, researchers showed that a traditional low-fat diet seemed to make the metabolism more sluggish than a high-protein one during the most difficult part of weight loss: keeping fat off once it's shed.

Blocking "don't destroy me" signals that normally sit on the surface of tumor cells and render them resistant to immune-cell attack slows the growth of a broad range of human cancers when they're implanted in mice, researchers have found. The approach, reported by immunologists at the Stanford University School of Medicine, was effective against ovarian, breast, colon, bladder, liver, prostate and brain cancer cells. If the work can be repeated in people, the approach may someday help doctors marshal defender cells in patients' own bodies to fight cancers, the researchers said.
