Study Offers Hope for Baldness Remedy

Study Offers Hope for Baldness Remedy - Common baldness could have its roots in a newly identified stem cell defect, a finding that could potentially lead to new hair-loss treatments down the road, a new study reveals.

Researchers say they discovered that a cellular malfunction short-circuits the process by which hair follicle stem cells turn into hair-producing progenitor cells. That defect, rather than any loss of stem cells themselves, sparks the onset of androgenetic alopecia, the medical term for a type of genetic hair loss that affects both men and women, they report.

In men, this hair loss is commonly known as male pattern baldness, marked by the familiar receding hairline and thinning hair on top of the head -- a condition that sometimes leads to complete baldness. In women, female-pattern hair loss causes the hair to get thinner all over but rarely leads to baldness.

The findings offer "a lot more hope that you could actually get hair to grow in a bald scalp," said study co-author Dr. George Cotsarelis, chairman of the dermatology department at the University of Pennsylvania School of Medicine Cotsarelis.

Man Hits Teen on Plane Over iPhone

Man Hits Teen on Plane Over iPhone - Police say a man on a Southwest Airlines flight from Las Vegas punched a teenager who refused to turn off his iPhone as the plane approached the Boise airport. Officers arrested 68-year-old Russell E. Miller, of Boise, on suspicion of misdemeanor battery Tuesday. He has been released from jail on bond. Witnesses told police the 15-year-old was playing games and listening to music on his cell phone when flight attendants instructed passengers to turn off their electronic devices because the plane was landing. Witnesses told police that when the teen didn't respond, Miller got angry and punched the boy in the arm. Miller says he "tapped" the teen on the shoulder after he refused to turn off the phone. He told the Idaho Statesman that he may have "overreacted," but that he did not punch the teen. Man Hits Teen on Plane Over iPhone

Interac’s first two Flash issuers are Scotiabank and RBC Royal Bank, which will roll out their first contactless cards next summer.
