The new blond is bound to be green—that is if chemists at a Japanese beauty company have their way. New research, presented today at the American Chemical Society meeting in Salt Lake City, has uncovered an enzyme that can remove dark pigment from hair.
The bold beauty work, led by Kenzo Koike, a researcher at the Kao Corporation in Tokyo, aims to take some of the bite out of bleaching, which is accomplished these days by using harsh hydrogen peroxide to break down the dark pigment melanin. The possible alternative should be easier on the environment, the body and the hair, Koike noted in a statement.
But beauty buffs beware, the find is très natural: it's actually an enzyme from a kind of "white rot" fungus known as Basidiomycete ceriporiopsis found in forest soil. And it can't quite fly solo. The enzyme still needs a bit of peroxide to do its job, but the quantities promise to be far less than what's in most bleaches now. But eco- and health-conscious bottle blonds shouldn't hold their breath (except perhaps to dampen that stinky bleach smell)—a consumer version of the stuff is still likely a ways off. Koike and his team are planning more tests to better understand just how the enzyme works—and make sure it's as safe as it seems.

Fingerprinting and analysis of hair fibers and marks made by weapons are familiar forensic tools to those of us who love crime shows, never mind to criminal defendants on trial and those who say they were wrongly convicted by evidence based on those techniques.
So you may be surprised to learn that none of those methods—which comprise the majority of what most real-life labs do—have been scientifically validated, and of the techniques commonly used in the nation's forensic labs, only DNA analysis has been rigorously proved to match a suspect to a crime.
Those are the conclusions of a new report released yesterday by the National Academy of Sciences (NAS). "In terms of the reliability and accuracy in making individualization conclusions, it is fair to say that, with the exception of nuclear DNA analysis, there is a lot we do not know about other forensic disciplines," said the NAS panel's co-chair, Constantine Gatsonis, director of the Center for Statistical Sciences at Brown University, in a statement.

Could a new eyelash-lengthening drug curb the envy of stubby-lashed ladies? The Food and Drug Administration (FDA) has green-lighted Latisse, which lengthens, thickens and darkens eyelashes when dabbed daily on the lash line on the lids with a disposable wand.
The med, called Latisse, should be available by March from a doctor or with a prescription from one. Price tag: $120 for a month’s supply. According to manufacturer Allergan, the drug usually nets results two to four months after users start it. Potential side effects: Some 4 percent of users experience eye itching and redness, and it may also temporarily darken the skin of the eyelid, according to the company.
The active ingredient in Latisse is bimatoprost, a compound derived from fatty acids that bind to receptors in the eyelashes that may be involved in the development and re-growth of hair follicles. Allergan has used bimatoprost since 2001 in Lumigan, an Rx eye drop that lowers eye pressure in people with glaucoma. (Glaucoma is a disease that may cause vision loss from damage to the optic nerve if too much pressure builds up in the eye.)
