Gardeners are famous for recycling. They convert kitchen scraps to compost, stake tomatoes with old pantyhose, and hang unwanted CDs on sticks to spook birds in the berry patch. But there's one thing every gardener buys that routinely gets tossed in the trash and buried in a landfill: the plastic flower pots used to grow seedlings. They're everywhere, especially at this time of year. They don't decompose, and they're not usually made of the plastic recycled in these parts.

For years, doctors have said it was impossible to predict, with rare exceptions, who was doomed. But yesterday, Thomas Jefferson University researchers said they have discovered a gene that causes the disease and will soon have a saliva test to identify those at risk. Doctors had thought that the blowout, called a ruptured aneurysm, was related to atherosclerosis, which is a form of hardening of the arteries. But the new research suggests that the primary cause is a genetic defect that weakens the walls of the aorta.

Connaught Laboratories Inc., a manufacturer of vaccines and biological products in Swiftwater, Monroe County, Pa., has formed a joint venture with Liposome Co. of Princeton. The two firms intend to use liposome technology to develop a more effective influenza vaccine. Liposomes are manmade microscopic spheres composed of naturally occurring substances known as lipids. The liposomes can be loaded with a cargo of drugs or therapeutic products that otherwise would be dispersed and destroyed in the body.

IT'S THE KIND of tale that would make anyone's skin crawl. Gary Dudek, 54 of Wallingford, Delaware County, allegedly stole $357,000 worth of human skin from Mercy Philadelphia Hospital from November 2011 to July of last year. Hospital employees were conducting record checks in the bioscience department in January when they saw Dudek take skin grafts to his car, according to court records. And although the employees weren't sure how long this allegedly had been going on, they found past surveillance footage of two similar instances.

Nicholas A. Kefalides, 86, of Merion, a physician, a groundbreaking scientist, and an educator, died Friday, Dec. 6, at his home from complications of pulmonary fibrosis. Dr. Kefalides was emeritus professor of medicine at the University of Pennsylvania, and remained active until his final days as a member of the medical school's admissions committee. In 1970, he began what would become a 43-year career at Penn and a high-profile role as a pioneer in the study of the extracellular matrix - components of the body that fill the space between structured cells.

Question: I got an e-mail that described using egg whites to treat a bad burn. It said the collagen protein in egg whites helped heal the burn. Is that really true? Answer: No, it's not. Placing egg whites on a second-degree burn (blistering skin) or a third-degree burn (a burn through the entire thickness of the skin) places the person at high risk of salmonella bacteria entering through a defect in the skin to cause illness. Salmonella bacteria are commonly found in raw eggs, and burned skin acts as an excellent culture medium for all sorts of bacteria.

Vagina envy is real. So, instead of leaving well enough alone, some women are opting to get a so-called designer vagina and undergoing labiaplasties to contour floppy, protruding inner lips. Some also are seeking liposuction to slim fatty pubic mounds. Although some patients request medical intervention because the way their bodies are configured makes them feel uncomfortable riding bicycles or doing other physical activities, the single biggest reason women request genital cosmetic surgery is aesthetics.

DOWNWARDLY MOBILE Will young adults in the United States be less affluent than their parents? Yes, says Lawrence Mishel, co-author of The State of Working America. Mishel, research director of the Economic Policy Institute in Washington, says the economic position of the typical young family deteriorated during the 1980s as a result of a fall in real wages, the shift in employment toward low-wage industries, the effects of large trade deficits, and the erosion of union membership.

The plate at the restaurant in Beijing was laden with thin, yellowish sheets made from soybeans, called tofu skin. Peter Lelkes used them as the chef intended, to wrap vegetables into bite-size morsels. But as he ate, the biomedical engineer's thoughts strayed from the Chinese restaurant to his lab in Philadelphia. The tofu-based "skin," he realized, made him think of the real thing. A decade later, that chance encounter in a Chinese restaurant has led to a soy-based "skin substitute" - a wound dressing that a start-up company has licensed for use on diabetic ulcers, burns, and other injuries the body cannot readily heal on its own. Lelkes and his Temple University colleagues say the product has shown promise in animal studies, and the company, Eqalix in Reston, Va., is raising money to seek FDA approval.
