Barence writes "It's desolate, dirty, and sex is outcast to a separate island. In this article, PC Pro's Barry Collins returns to Second Life to find out what went wrong, and why it's raking in more cash than ever before. It's a follow-up to a feature written three years ago, in which Collins spent a week living inside Second Life to see what the huge fuss at the time was all about. The difference three years can make is eye-opening."

hackingbear writes "Wired, citing a paper published in Science magazine, reports that Harvard scientists may have found a safer way of giving a flake of skin the biologically alchemical powers of embryonic stem cells by turning adult cells into versatile, embryonic-like cells without causing permanent damage. The technique involves 'adding cell-reprogramming genes to adenoviruses, a type of virus that infects cells without affecting their DNA.' Four-month trials on mice demonstrated that the resulting stem cells are free from unpredictable cancer-inducing mutations. This is definitely a breakthrough in stem cell research." Additional coverage is available at Yahoo, and Science hosts the research paper, although you'll need a subscription to see more than the abstract.

TaeKwonDood tips us to news that a new cancer resistance treatment is going into clinical trials after being quite successful at eradicating cancer in mice. Researchers discovered that certain white blood cells called granulocytes from cancer-immune mice were able to cure cancer in other mice. Now, doctors are putting out the call for healthy granulocyte donors in order to test how well it works on humans. The article quotes lead researcher Zheng Cui saying, "In mice, we've been able to eradicate even highly aggressive forms of malignancy with extremely large tumors. Hopefully, we will see the same results in humans. Our laboratory studies indicate that this cancer-fighting ability is even stronger in healthy humans."

snydeq writes "Rapamycin, a medication doctors prescribe to transplant patients to prevent organ rejection, has been used to reverse learning disorders and mild retardation associated with TSC (tuberous sclerosis complex) in mice. Because the condition is linked to autism, scientists believe the drug may be used to treat learning disabilities and short-term memory deficits in all kinds of autism as well. The scientists chose rapamycin after they realized the drug regulates one of the same proteins that the TSC gene does, just in different parts of the body. 'What was surprising is that we could give rapamycin to adult mice and reverse their condition,' said neurobiologist Alcino Silva of the David Geffen School of Medicine at UCLA. 'We did not know ... that this drug would be equally effective for the learning disabilities as it is for tissue rejection.' Rapamycin treatment leveled the playing field between normal and TSC mice in as little as three days."

Genetically engineered cells implanted in mice have cleared away toxic plaques associated with Alzheimer's disease. The animals were sickened with a human gene that caused them to develop, at an accelerated rate, the disease that robs millions of elderly people of their memories. After receiving the doctored cells, the brain-muddling plaques melted away. If this works in humans, old age could be a much happier time of life.

noahisaac writes "My brother just sent me an article he posted for the Rett Syndrome Research Foundation about a cure for Rett Syndrome, a form of autism. According to the article, researchers successfully re-introduced a fully functional version of the MECP2 gene into mice that had been born with damaged MECP2 genes. Contrary to their expectations, the mice improved. In the article's words, 'restoration of fully functional MECP2 over a four week period eradicated tremors and normalized breathing, mobility and gait in mice that had previously been fully symptomatic and, in some cases, only days away from death.' The ramifications for people suffering from Rett Syndrome are obvious, but mutations of the MECP2 gene are also believed to be the cause of 'classic' autism, and a number of other neurological disorders."

theshowmecanuck writes to mention that in a recent study, researchers at the University of Alberta Department of Medicine have shown that an existing small, relatively non-toxic molecule, dichloroacetate (DCA), causes regression in several different cancers. From the article: "But there's a catch: the drug isn't patented, and pharmaceutical companies may not be interested in funding further research if the treatment won't make them a profit. In findings that 'astounded' the researchers, the molecule known as DCA was shown to shrink lung, breast and brain tumors in both animal and human tissue experiments."
