In the war against pests, the lowly cockroach makes for a fearsome adversary. It can go weeks without water, survive decapitation for a time - and, like any proper super-villain, can send humans screaming from a room. Now researchers have discovered how some roaches have eluded humans' once-infallible traps: They have evolved so that glucose-sweetened bait tastes bitter. The discovery, published in Friday's edition of the journal Science, solves a 20-year mystery and sheds light on the cockroach's powerful ability to adapt.

When James Watson and Francis Crick deciphered the structure of DNA in 1953, their discovery answered a crucial question in biology: How is genetic information passed down from parent to child? Their work also created conundrums, however. They and others showed that every cell of an organism contains all of its genetic material. How, then, does an individual cell know which genes to use and when? And how does information from DNA get to the cell's protein-making machinery? The seminal insight into those questions came from three biologists at the Pasteur Institute in Paris - Dr. Francois Jacob, Jacques Monod and Andre Lwoff.

After gastric bypass surgery, people with Type 2 diabetes often see their disease completely disappear - within weeks, before they've lost much or any weight. It doesn't work for everyone, though. What are the factors that matter? A study by a team of scientists from the University of Massachussetts looked into that. Here are their findings, which were presented at the annual meeting of the American Society for Metabolic and Bariatric Surgery. The scientists looked at remission of diabetes in 139 patients, ages 48 to 57, who'd had gastric bypass surgery.

Diabetes affects more than 25 million Americans. New medications and strategies to treat the disease are greatly needed. But the jury is still out on the experimental medication dapagliflozin. The medication looks to have significant benefits and risks, according to a study published Monday. Dapagliflozin is being developed by Bristol-Myers-Squibb Co. in partnership with AstraZeneca. It represents a new class of diabetes medications called selective renal sodium glucose contransporter inhibitors.

A short while ago, Lars came in for a visit. He's a friendly, happy-go-lucky guy with a desk job in some sort of marine industry. The bulk of his visits have revolved around his passion for softball. He plays on three teams year round, and from time to time his competitive edge gets the better of him and he twists an ankle or pulls a muscle and comes in to get patched up. I remind him he's 45, not 25, that it's not Game 7 of the World Series, that he should go a little easy on himself.

Smart phones have already supplemented the doctor’s office and personal computers as sources of health advice — and now it appears car companies are driving into the on-the-go consumer health market. Ford is developing a way to display pollen counts and other allergen levels to drivers using its existing link to smart phone apps, the car company announced Wednesday. Ford has also made a prototype to synchronize glucose monitoring devices via Bluetooth. The car displays glucose levels and sounds an alert if they fall too low. A statement from Ford explains how this technology can help diabetics and allergy sufferers: “For people with diabetes and their caregivers, constant knowledge and control of glucose levels is critical to avoiding hypoglycemia or low glucose, which can cause confusion, lightheadedness, blurry vision and a host of other symptoms that could be dangerous while driving.
