...field of biological aging has in recent years focused on the long molecules of DNA contained in human cells called chromosomes. All chromosomes have protective caps at either end called telomeres. Each time a cell replicates itself (as it does before it dies), the telomeres shorten, like plastic tips fraying on the end of shoelaces. Shortened telomeres have been linked to a host of age-related illnesses such as heart disease and certain cancers. (Scientists have yet to study whether telomeres influence a person's appearance.) Last year's Nobel Prize for Medicine was awarded to three American scientists...
Itching for a good after-school science experiment? Researchers at Rutgers University in New Jersey have created a homemade bedbug trap using a plastic cat-food dish, an insulated jug and some dry-ice pellets. According to Wan-Tien Tsai, who reported her findings in December at the annual meeting of the Entomological Society of America, the dry-ice-and-thermos combo captured the bloodsucking critters in an infested apartment just as effectively as, if not more so than, equipment used by professional exterminators. (See the fascinating, frightening world of insects...
Once properly liquored up, the attendees headed to prom. Ropes Gray, a large room in Pound Hall, was covered in plastic flamingos and colored streamers. “It’s a big room with a DJ and beer and people dancing,” said Hurvitz. “There isn’t a whole lot more to it.” Sounds just like a d-hall party, minus the seven-dollar entry...
Nutty as "mycotecture" sounds, Ross may be onto something bigger than an art project. A promising start-up named Ecovative is building a 10,000-sq.-ft. (about 930 sq m) myco-factory in Green Island, N.Y. "We see this as a whole new material, a woodlike equivalent to plastic," says CEO Eben Bayer. The three-year-old company has been awarded grants from the EPA and the National Science Foundation, as well as the Department of Agriculture--because its mushrooms feast on empty seed husks from rice or cotton. "You can't even feed it to animals," says Bayer...
Back before protests erupted last June, if you were to see a crowd gathered on the streets in Tehran, odds were that people were buying up the latest U.S. hit movie or television show from a black-market vendor. Customers flip through piles of plastic sleeves, looking for an unseen classic or the latest that the Americans have to offer: Avatar, District 9, Invictus, the second Night at the Museum, the first Godfather. One can find Desperate Housewives and 24. At about one toman each (approximately $1), the DVDs are affordable as an occasional indulgence for most residents...
