Skin cancer is the most common malignancy in the US, says the American Academy of Dermatology, and one American dies every 62 minutes from melanoma. The WHO estimated that, in the year 2000, up to 71,000 deaths worldwide were attributed to excessive UV exposure.

Indoor tanning beds are not safe from UV risk despite what advertising claims are, according to a series of papers published in the October issue of Pigment Cell & Melanoma Research. There may be no such thing as a 'safe' tan based on ultraviolet (UV) radiation, they write.

The authors of the three review papers have examined the effects on skin of UV radiation, including that from indoor tanning beds. As well as highlighting the need for greater research into this area, they have called for the use of such beds by under-18s to be banned, along with any publicity that claims that tanning beds are safe.

Biologists at the University of Rochester writing in Aging Cell have found that small-bodied rodents with long lifespans have evolved a previously unknown anti-cancer mechanism that appears to be different from any anti-cancer mechanisms employed by humans or other large mammals.

Understanding this mechanism may help prevent cancer in humans because many human cancers originate from stem cells and similar mechanisms may regulate stem cell division.

"We haven't come across this anti-cancer mechanism before because it doesn't exist in the two species most often used for cancer research: mice and humans," says Vera Gorbunova, assistant professor of biology at the University of Rochester, a principal investigator of this study. "Mice are short-lived and humans are large-bodied. But this mechanism appears to exist only in small, long-lived animals."

Researchers know that high blood pressure causes blood vessels to contract and low blood pressure causes blood vessels to relax but no one had the tools to determine the exact proteins responsible for this phenomenon.

By using atomic force microscopy and isolating blood vessels outside the body, University of Missouri researchers have identified a protein that plays an important role in the control of tissue blood flow and vascular resistance. This new knowledge brings researchers one step closer to understanding vascular diseases, such as high blood pressure, diabetes and other vascular problems.

Plants in a forest respond to stress by producing significant amounts of a chemical form of aspirin, scientists have discovered. The finding, by scientists at the National Center for Atmospheric Research (NCAR), opens up new avenues of research into the behavior of plants and their impacts on air quality, and it also has the potential to give farmers an early warning signal about crops that are failing.

For years, scientists have known that plants in a laboratory may produce methyl salicylate, which is a chemical form of acetylsalicylic acid, or aspirin. But researchers had never before detected methyl salicylate in an ecosystem or verified that plants emit the chemical in significant quantities into the atmosphere.

A hormone found at higher levels when the body produces its own "home grown" fat comes with considerable metabolic benefits, according to a report in Cell. The newly discovered signaling molecule is the first example of a lipid-based hormone; most are made up of proteins.

The findings in mice raise the notion that boosting the body's fat production might actually be one solution to the growing epidemic of obesity and related metabolic diseases. Likewise, diets supplemented with the fat hormone, a fatty acid known as palmitoleate, might also come with long-term benefits.

The results also reveal that, as with most things, when it comes to fat it's not good to generalize.

- Call for Massive Investment in Health Visiting to Meet Government Goals

A quarter of health visitors in England fear that 'another Victoria Climbie' could happen in their NHS trust, new research from Unite, the country's largest trade union, revealed today (Thursday, 18 September).

The survey by Unite/Community Practitioners' and Health Visitors' Association of 829 health visitors in England revealed 25% thought the chances of a repetition of the fate of the eight-year old girl tortured to death by her great-aunt and her boyfriend happening in their NHS trust was 'very likely' or 'somewhat likely'.

It drives me mad when I hear a guy complain that he eats and eats but can’t gain weight, and that he resorts to drinking protein shakes to “bulk up.” [Insert world’s smallest violin playing here.] Excuse me? Did I hear him right? He gorges himself when I’ve sworn off pasta, meat, birthday cake--my only nutritional intake: a bottle of water and a carrot stick between classes, all so I can decrease my bulk?

Argh. But really, Pfizer (and those men) take the cake even when it comes to Lipitor.
