Oh Boy—Is Mom Hungry!
At birth, boys tend to weigh about 100 grams (3.5 ounces) more than girls. An international research team wondered whether that meant that boys’ moms ate more during pregnancy. In data published this week, the scientists now confirm that’s exactly what happens. Though women eat more when carrying a boy, they don’t gain more weight […]

Wash Those Hands!
A Florida-based company is now developing a laser-based scanning technology to scout for dirty hands. Installed in restaurant washrooms or daycare centers, it could identify fecal traces — evidence that hand washing was incomplete. Indeed, these sensors might even be coupled to a lock that allows workers back into a kitchen after a restroom break, notes Richard Stroman, vice president of eMerge Interactive, which is applying for a patent on the system. Kitchen or food-processing-plant workers who don't pass the laser test would be forced to go back and lather up again.

Hyperbolic Five
Dutch graphic artist M.C. Escher (1898–1972) devised many highly original schemes in his attempts to capture the concept of infinity visually. One strategy he often employed was to create repeating patterns of interlocking figures. However, although he could imagine how such arrays extended to infinity, the actual pattern he drew represented only a fragment of […]

No Way to Make Soup—Thirty-two tons of contraband shark fins seized on the high seas
Something looked suspicious. This former swordfishing vessel, out of Honolulu, was clearly heavy with cargo when discovered by U.S. law-enforcement officials 350 miles off of Acapulco, on Aug. 13. A boarding team found no fishing–just shark fins. However, under a new federal law, transporting fins collected by another fishing vessel constitutes illegal “fishing.” US Coast […]

Another Green That Might Prevent Breast Cancer
Many studies have indicated that diets high in produce–including broccoli and other veggies–may lower a woman’s risk of developing breast cancer. Now, California researchers report data suggesting that drinking green tea does the same thing. Bad news for women who–like me–prefer black tea: The study failed to identify a similar advantage from such brews, much […]

While reading that the cranial crest of the pterosaur Thalassodromeus helped regulate body temperature, I pondered another potential use. While gliding near the water, its crested head might act as a rudder for the large-wingspan animal. Perhaps the crest also included nerves that allowed Thalassodromeus to sense fleeing fish. Steve M.

Darn that diet, anyway
Seemingly healthful foods—such as broiled chicken and baked fish—can contain high concentrations of compounds that may damage the cardiovascular system, and eating these foods can raise the concentration of these so-called advanced glycation end products in a person's blood.
