Councilman William Greenlee hopes not to get burnt Thursday when his indoor-tanning bill comes up for a vote. Citing what he called "a preponderance of evidence" that indoor tanning greatly raises one's risk of developing skin cancer, Greenlee has introduced a bill that would restrict minors from using indoor-tanning facilities in Philadelphia without parental permission. The measure would also prohibit those younger than 14 from using commercial tanning beds and other ultraviolet-emitting equipment without a doctor's permission.

The scientist and his companions puttered down winding waterways by boat, and bounced along dirt roads in a Ford Explorer. The longest of more than a dozen such trips into the Malaysian jungle took 10 hours. Only then could the researcher from Penn State College of Medicine ask tribal leaders for the information he sought: Surat warisan manusia . The letter of human inheritance. That was Khai C. Ang's way of explaining the concept of DNA, and it was effective. Hundreds of villagers agreed to give blood samples, and now back in the Hershey, Pa., lab of Ang's supervisor, Keith Cheng, their DNA has begun to yield insight into a weighty trio of subjects: cancer, human migration, and race.

A new campaign by the tanning industry to promote the safety of sunbed use has been attacked by the American Academy of Dermatology as "ridiculous" and unsupported by scientific evidence. The dermatologists blasted the newly formed American Suntanning Association for disputing the medical consensus that tanning indoors raises the risk of skin cancers, such as melanoma, the deadliest kind. The launch last month of the tanning association, made of up to 1,400 salon owners, marks an escalation in the $5 billion industry's campaign to rebut the mounting evidence of the harm from indoor tanning.

As both a science writer and a melanoma survivor, I eagerly attend the annual scientific retreat of the Melanoma Research Alliance, which funds cutting-edge research on the skin cancer. Last year, the first drug targeting a genetic defect that causes melanoma, vemurafenib, came on the market with much fanfare. But at this year's meeting, researchers reported that the drug would not cure most melanoma patients because they eventually develop drug resistance. Much of the research reported at this conference delved into what caused vemurafenib to fail in so many patients, and what new drugs it could be combined with to be more effective.

On June 9, Commerce Secretary John Bryson was hospitalized after his reported involvement in three auto accidents. Although details were not disclosed, the White House confirmed that he had a seizure. On July 30, 2007, Chief Justice John Roberts collapsed on a boat dock at his Maine summer home. Although that seizure was Roberts' second, he offered little explanation. When Time magazine asked "Does Justice Roberts Have Epilepsy?" Roberts didn't answer, and he hasn't in five years.

Edward Williamson was no sun worshipper. In fact, most of his life he diligently avoided it. "I never saw my father with his shirt off," recalls his daughter Tara Coates. "He didn't enjoy being out in the sun and on the beach. " Adds his son Greg: "He worked indoors all life; his skin was the color of milk. " The one thing that drew him outdoors was golf, a favorite pastime. He wore a hat and covered his arms. The only part of his body that was exposed was the small area of his neck where his golf shirt parted to form a V. And it was there in 2005, when Williamson was 59, that his wife, Adell, noticed a suspicious-looking flat brown patch.

Sunscreens should be used regularly by people of all ages to prevent skin cancer, including the most dangerous form of cancer linked to sunburns: melanoma. However, a new study shows that kids are really bad about using sunscreen consistently. Researchers studied fifth-grade children in Massachusetts in 2004 and then resurveyed the same 360 children three years later. In the first survey, more than half of the kids said they had experienced at least one sunburn, and this rate did not change three years later.

Eliminates wrinkles. Removes blemishes. Reduces pore size. Reverses the effects of aging. These are just a sampling of claims in an overwhelming market of skin-care products. Sound too good to be true? Usually, it is. In most cases, the benefits have not been adequately tested, and the claims may be greatly exaggerated, since cosmetics do not go through a U.S. Food and Drug Administration approval process. But this doesn't mean good skin-care products can't be found - and on a budget.

As the darkest days of the year close in, some of us crave the feel of sunlight on our skin. That could reflect our evolutionary heritage, since we humans are not well-adapted to live as far north as Philadelphia. We're essentially an equatorial, tropical species who migrated only recently to places with long, dark winters. There hasn't been time to adapt. One major problem with living this far from the equator is that it's hard to get enough Vitamin D, a hormone that turns out to be essential not only for keeping our bones strong but also for running our immune systems and just about everything else.

Issa: Subpoenas are due soon WASHINGTON - The chairman of the House oversight committee said Sunday that he could send subpoenas to the Obama administration as soon as this week over weapons lost amid the Mexican drug war. Rep. Darrell Issa (R., Calif.) suggested on Fox News Sunday that Attorney General Eric H. Holder Jr. knew about the gun-trafficking operation known as Fast and Furious earlier than he has acknowledged. In the 2009 operation, the Bureau of Alcohol, Tobacco, Firearms and Explosives let intermediaries for drug cartels buy thousands of weapons from Arizona gun shops and lost track of about 1,400 of the 2,000 guns.
