Stem cell 'cure' boy gets tumour

A boy treated with foetal stem cells for a rare genetic disease has developed benign tumours, raising questions about the therapy's safety.

The boy, now 17, received the stem cells in 2001 at a Moscow hospital and four years later scans showed brain and spinal tumours, PLoS Medicine reports.

Israeli doctors removed the abnormal growth from his spine and tests suggest it sprouted from the stem cells.

Flashback Rhodiola Rosea: The Herb That Came in From the Cold

For four hours, the unlikely trio made its way up the rugged face of the Sayan Mountains in northern Mongolia - Richard P. Brown, an American psychiatrist and psychopharmacologist, Zakir Ramazanov, a distinguished Russian plant biochemist, and their Siberian guide. Under a cloudless sky of the deepest blue, they climbed quickly, the temperature falling and the oxygen growing thinner as they gained altitude. At last, after climbing more than 10,000 feet over icy streams and rugged rock faces, they crested the last ridge. "We stood and stared in amazement," remembers Brown. "Everywhere we looked, growing in the craggy mountain ravine, were the bright yellow flowers of Rhodiola rosea."

Brown began digging around for information about the little-known herb, which is also called Arctic root or golden root. When he contacted an American company that produces a rhodiola supplement, he was advised to speak with Ramazanov, who had done research on the herb in Russia, where the plant grows. "By an incredible coincidence, Ramazanov had just moved to the United States and was living only an hour away from me," says Brown.

The two men agreed to get together, and during their first meeting the Russian biochemist gave Brown a tall stack of articles and research studies, as well as a book he'd written about the herb. "I realized then that there was much more to this than I'd ever imagined," says Brown.

How We Think Before We Speak

We engage in numerous discussions throughout the day, about a variety of topics, from work assignments to the Super Bowl to what we are having for dinner that evening. We effortlessly move from conversation to conversation, probably not thinking twice about our brain's ability to understand everything that is being said to us. How does the brain turn seemingly random sounds and letters into sentences with clear meaning? In a new report in Current Directions in Psychological Science, a journal of the Association for Psychological Science, psychologist Jos J.A. Van Berkum from the Max Planck Institute in The Netherlands describes recent experiments using brain waves to understand how we are able to make sense of sentences.

FDA: Three Deaths from PML Tied to Genentech Psoriasis Drug Raptiva

Three patients taking Genentech's psoriasis drug Raptiva are thought to have died of a rare brain infection, known as a possible side effect of the drug, federal health officials reported.

On Thursday, the Food and Drug Administration said there have been three confirmed and one possible case of progressive multifocal leukoencephalopathy or PML in people taking Raptiva. Three of the patients died. All four had been treated with the drug for more than three years.

US: Incurable cancer blamed on water at Marine base

Allen Menard is proud to be a U.S. Marine.

"Love of country comes first," said the Green Bay man, holding a picture of his younger self, standing tall in military fatigues.

But the 45-year-old thinks the military downplayed the presence of toxins in the water supply at Camp Lejeune, N.C., where Menard was stationed from 1981-84. He believes the contaminated water contributed to his rare, noncurable skin cancer.

Breast cancer biology 'changing'

Breast cancer is the commonest cancer in UK women
Lifestyle changes and screening have shifted the type of breast cancers women are diagnosed with over the past couple of decades, research suggests.

Women are now more likely to have hormone-dependent, slow-growing tumours, a comparison of tissue samples from the 1980s and 1990s shows.

The Scottish researchers also found improved survival over time, the British Journal of Cancer reported.

More than 40,000 women are diagnosed with breast cancer in the UK annually.

Previous studies have suggested that breast cancers may be more commonly hormone-dependent than in the past.

Specifically it is thought that oestrogen-receptor positive cancers may be on the rise.

Flashback Bringing the Culture Back in Agriculture

After the turn of the previous century there was a lot of experimentation with mono cultures. By that is meant growing only one field crop, e.g. corn or wheat. This is a principle that goes against nature, which works with ecosystems based on synergy and complex wholes, whereby plants work together and support one another. Some plants root deeper than others, allowing them to uptake minerals from underneath the topsoil. When these plants die, their rich mineral content in turn fertilizes the soil. This is how nature creates her own cycle. On natural grasslands you will always find clover and herb species. Clover gets its minerals from deep inside the ground and the herbs fulfill a healing role in the ecosystem.

Flashback U.S. Farmers Can Barely Keep Up With Demand for Organic Produce

The demand for organic food in the United States outstrips the supply, according to industry groups such as the Organic Trade Association (OTA) and Organic Farming Research Foundation. This means that imports of organic food are rising, but industry leaders want the U.S. government to take steps to help boost domestic production.

US: Most fertility clinics break the rules

New York - The California fertility doctor who implanted the octuplet mom with lots of embryos was no lone wolf: Fewer than 20 percent of U.S. clinics follow professional guidelines on how many embryos should be used for younger women. "Clearly, most programs are not adhering to the guidelines," said Dr. Bradley Van Voorhis, director of the fertility clinic at the University of Iowa.

The furor over Nadya Suleman and her octuplets has brought scrutiny to U.S. fertility clinics and how well they observe the guidelines, which are purely voluntary. The controversy had led to talk of passing laws to regulate clinics, something that has already been done in Western Europe.

"There are enough clinics that quite openly flout professional guidelines that we really do need to start thinking about public policy in this area," said Marcy Darnovsky of the Oakland, Calif.-based Center for Genetics and Society, a public interest group. "I think it's way overdue."

Violent Media Numb Viewers to the Pain of Others

Violent video games and movies make people numb to the pain and suffering of violent media also affect someone's willingness to offer help to an injured person,others, according to a research report published in the March 2009 issue of Psychological Science.

The report details the findings of two studies conducted by University of Michigan professor Brad Bushman and Iowa State University professor Craig Anderson.

The studies fill an important research gap in the literature on the impact of violent media. In earlier work, Bushman and Anderson demonstrated that exposure to violent media produces physiological desensitization - lowering heart rate and skin conductance - when viewing scenes of actual violence a short time later. But the current research demonstrates that violent media also affect someone's willingness to offer help to an injured person, in a field study as well as in a laboratory experiment.
