In this month's issue of Nature
, Haruko Obokata and colleagues have made a breakthrough in the field of stem cell research, where they describe a unique cellular reprogramming phenomenon in which skin and blood cells could be converted into stem cells without the need to physically manipulate the nucleus or over-express reprogramming genes. Rather, the researchers subjected them to stress "almost to the point of death", by exposing them to various events including trauma, low oxygen levels and acidic environments. One of these "stressful" situations was simply to bathe the cells in a weak acid solution for about 30 minutes. Within days, the scientists found the cells had not only survived but had also recovered by naturally reverting into a state similar to that of an embryonic stem cell.
The research suggests human cells could in future be reprogrammed by the same technique, offering a simpler way to replace damaged cells or grow new organs for sick and injured people. [more inside]

are a system of classification of colors represented by an alphanumeric code, allowing accurate recreation in any medium. Humanae
is a project from Spanish artist Angelica Dass that applies the alphanumerical classification of the PANTONE® coloring system to human skin tone, communicated through a photographed portraiture series. The exact shade is extracted from a sample of 11x11 pixels from the face of the people portrayed. The ongoing aim is to record and catalog human skin tones through scientific measurement.

Many people are familiar with computer case modifications
, thanks to the photogenic nature of mods
. On the software side, most operating systems feature some potential for customization, though this is often limited to tweaking the colors and sounds. For some, this isn't enough. Enter "skinning
," the casual term for interface customization. To a degree, the history of the media player Winamp
(YT, 7:03; transcript with pictures
) mirrors the history of skinning. From a version 0.2, a visually dull app in June 1997, to easy user customization in version 2 in September 1998, and the complexly customizable Winamp3 in August 2002. Wired captured something of the excitement at its peak
in an article from 2000, before computing began shifting to more closed devices. Now approaching a post-WIMP (windows, icons, menus and a pointer) era
, where skinning is done with alternative launchers
. But for those still using traditional computers of one sort or another, it's not too late to modify your interface. [more inside]

Exposing our skin to the sun's ultraviolet rays unfortunately can give rise to a multitude
of adverse health effects. Our skin's ability to produce melanin
serves as buffer by absorbing those nasty UV rays. But how exactly does our skin know when it's being exposed to UV light? Well, apparently it can see
it. [more inside]

Dr. Jörg C. Gerlach
has developed a new device for applying a regenerative skin and stem cell slurry onto burn victims in an airbrush-like spray - providing astounding results
in mere days. (Warning - mildly graphic images of severe burns being remedied with SCIENCE!)

I have psoriasis
. I am among the 2-3% of the world population has it. It is a skin condition
with a genetic component
(thanks mom and dad). It means that I have white plaques on my skin that itch and shed flakes
. I shed so much that I have to sweep my floors daily. I have plaques mainly on my arms and legs, but they can appear anywhere (some locations linked from this page are NSFW
. I'm lucky, I don't have psoriatic arthritis
which affects about a third of all people with psoriasis. People stare at me or pretend not to stare at me in public. I wish they would just ask me
what it is. It isn't contagious. Sometimes people ask if I have a bad sunburn or a regular burn. Little kids ask about my boo boos. Dogs lick my legs
. There are several different
ways to treat psoriasis
including steroids, light treatment, injectable antibodies, and shampoos but it is a chronic condition. One treatment
was recently withdrawn from the market because of lethal side effects. There are groups
who have psoriasis
. As with many medical conditions, you sometimes get unwelcome
suggestions on how to cure it. When I used to work in a hospital environment, the pathologists showed me what it looks like
under a microscope.

As Armistice Day
approaches an exhibition reveals a hidden side to the horror of World War I.
It contains previously unseen images
of British servicemen who suffered terrible facial injuries in the conflict.
The exhibition also tells the story of one surgeon - Harold Gillies
– who through his efforts to help them became known as the father of modern plastic surgery.
WARNING: Some of the following images are of a very graphic nature.

It puts the lotion in the basket. [nsfw]
You know how in that movie, The Silence of the Lambs,
the serial killer they're trying to catch is skinning women because he wants to make a suit out of real girls?
If this product was around, perhaps we could have saved the lives of a lot of fictional victims.

Cancer be damned, kids wanna tan
“I know I might get cancer, but sometimes you want to look good no matter what. I’d rather look good that worry about what could happen to me–looks are more important to me sometimes than my health.” (Maclean’s Magazine)
Perhaps cancer is ‘natural selection’ at work trying to weed out all of societies undesirables from the gene pool. I for one think we could do without people this stupid.

Tax the tan?
a new study shows more than a quarter of white female teenagers have had at least three sessions in a tanning booth, Forty-seven percent of 18- and 19-year-old females made three or more visits. The overall rate for boys was far lower, around 7 percent. Note to teenage boys: Go hang out at the tanning booth.
Concerned dermatologists made a bold proposal: Slap a $20 tax on every visit to the tanning salon for people under 18, after all, we tax Smokes
for just the same reason.
Needles to say The Indoor Tanning Association
(Don't miss the upcoming ITAWorld Expo
, Huey Lewis and the News show included!), which represents the nation's 6,000 tanning salons, denounced the idea, noting that moderate exposure to ultraviolet light may actually promote health. UV light helps the body absorb vitamin D, which is important in the development of bones. After all Nicotine 'reduces Alzheimer's symptoms'
. Are taxes a good behavior modification tool?

Close. Ok, not really. Not at all. Someone had a little too much time on their hands and deconstructed a bevy of actors and their skin conditions.
