Scientists crack ‘entire genetic code’ of cancer

Sometimes mutating is bad for you:

Scientists have unlocked the entire genetic code of two of the most common cancers – skin and lung – a move they say could revolutionise cancer care.

Not only will the cancer maps pave the way for blood tests to spot tumours far earlier, they will also yield new drug targets, says the Wellcome Trust team. […]

The lung cancer DNA code had more than 23,000 errors largely triggered by cigarette smoke exposure.

From this, the experts estimate a typical smoker acquires one new mutation for every 15 cigarettes they smoke.

Although many of these mutations will be harmless, some will trigger cancer.

Psychiatry’s civil war

When doctors disagree with each other, they usually couch their criticisms in careful, measured language. In the past few months, however, open conflict has broken out among the upper echelons of US psychiatry. The focus of discord is a volume called the Diagnostic and Statistical Manual of Mental Disorders, or DSM, which psychiatrists turn to when diagnosing the distressed individuals who turn up at their offices seeking help. Regularly referred to as the profession’s bible, the DSM is in the midst of a major rewrite, and feelings are running high.

Two eminent retired psychiatrists are warning that the revision process is fatally flawed. They say the new manual, to be known as DSM-V, will extend definitions of mental illnesses so broadly that tens of millions of people will be given unnecessary and risky drugs. Leaders of the American Psychiatric Association (APA), which publishes the manual, have shot back, accusing the pair of being motivated by their own financial interests – a charge they deny. The row is set to come to a head next month when the proposed changes will be published online. For a profession that exists to soothe human troubles, it’s incendiary stuff. […]

Some of the most acrimonious arguments stem from worries about the pharmaceutical industry’s influence over psychiatry. This has led to the spotlight being turned on the financial ties of those in charge of revising the manual, and has made any diagnostic changes that could expand the use of drugs especially controversial. “I think the DSM represents a lightning rod for all kinds of groups,” says David Kupfer of the University of Pittsburgh, Pennsylvania, who heads the task force appointed by the APA to produce the revised manual.

Extreme Bio-Hacking: Wings and Tails for Humans

Great Moon Hoax of 1835

Dr. Joe Rosen at the Dartmouth Medical Centre believes that within five years he’ll be able to graft extra limbs such as wings and tails to humans. According to a Guardian Unlimited article “When we have a limb amputated, our neural map of that limb gradually fades away; and if we gain a body part, our neural map expands accordingly.” Rosen says “If I were to give you wings, you would develop, literally, a winged brain. Our bodies change our brains, and our brains are infinitely mouldable.”

Update: It appears that as of Spring 2007 Dr. Rosen is now more focused on facial reconstructive surgery than these more fringe pursuits.
