But Can It Grow Hair?

1 Cure for Baldness May Be Available Soon

Scientists at the U of Pa have identified a scalp chemical that stops hair from growing. The drugs that block the protein are already available and were developed for other purposes but, after reformatting them as a topical application and additional research, a cure for baldness may be available within 5 years. Research centers on the protein PDG2 that, in animal and lab tests, stunted hair growth. The drugs that inhibit PDG2 are in pill form but “you can take compounds that maybe are being used as a pill and put them in a topical formulation. When you apply this to the scalp... you would allow hair to grow,” says lead author Dr. George Cotsarelis. The research team has high hopes for the drug’s ability to stop hair loss but they are unsure if it would generate regrowth.

Heart Disease, Cocaine Factors

2 Whitney Houston: Accidental Drowning in Tub

Whitney Houston's cause of death was accidental drowning with the "effects of atherosclerotic heart disease and cocaine use" as contributing factors, says the Los Angeles County Coroner. While Houston was discovered submerged in a bathtub that was full of water, no foul play is suspected. CNN reports that the toxicology tests revealed marijuana, Xanax (anti-anxiety drug), Flexeril (muscle relaxer), and Benadryl in her system, but the drugs didn't contribute to her death. The final report from the coroner should be made public in two weeks. Houston, 48, died on February 11, the day before the Grammy Awards in Los Angeles. She won six Grammys during her career.

Resident Memory T Cells in Skin

3 Transdermal Vaccines Boost Immunity Better

New research has led scientists to believe that delivering vaccines by scratching the skin may provide better immunity than the traditional intramuscular jab. The idea of intramuscular injections was to stimulate the immune cells in the bloodstream but studies are showing that the skin and lungs have immune cells that offer protection against pathogens. Skin contains immune cells known as “resident memory T cells” and studies in mice have shown they have a more protective effect than those in the blood. Other research on the flu vaccine patch, a little square with lots of tiny needles, has shown it to be more effective than those given subcutaneously or intramuscularly. Future research will look at how cells in the skin work with the rest of the immune system to maximize their potential.
