STANFORD, Calif. - Cancer starts when key cellular signals run amok, driving uncontrolled cell growth. But scientists at the Stanford University School of Medicine report that lowering levels of one cancer signal under a specific threshold reverses this process in mice, returning tumor cells to their normal, healthy state. The finding could help target cancer chemotherapy to tumors while minimizing side effects for the body's healthy cells.
A study reported in Vol 51, Issue 7 (July, 2008) of Science in China Series B: Chemistry has shown that wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings, are stable on corresponding potential hyper-surfaces. This suggests that the central element bonding capacities have not been exhausted.
Alexandria, VA Researchers have developed a series of tests that for the first time accurately measure the normality of taste (gustatory function) and smell (olfactory function) in young children, according to a new study published in the July 2008 edition of Otolaryngology Head and Neck Surgery.

United States has highest level of illegal cocaine and cannabis use
A survey of 17 countries has found that despite its punitive drug policies the United States has the highest levels of illegal cocaine and cannabis use. The study, by Louisa Degenhardt (University of New South Wales, Sydney, Australia) and colleagues, is based on the World Health Organization's Composite International Diagnostic Interview (CIDI) and is published in this week's PLoS Medicine.
We all know that smoking and drinking when pregnant can harm the baby, but new research published in The Journal of Physiology suggests that poor diet may also cause long-lasting, irreversible damage in offspring from heart disease to diabetes.
Stéphanie Bayol and Neil Stickland at the Royal Veterinary College, London fed female rats a "junk food" diet of crisps, cheese, muffins and other processed foods throughout pregnancy and lactation.
A general policy of copayments or top-ups, allowing patients to pay privately for drugs, would be counter to the principles of the NHS and grossly unfair to desperately sick people, say experts on BMJ.com today.
A laser-activated antimicrobial offers hope for new treatments of bacterial infections, even those that are resistant to current drugs. Research published today in the open access journal BMC Microbiology describes the use of a dye, indocyanine green, which produces bacteria-killing chemicals when lit by a specific kind of laser light.
Mothers who eat an unhealthy diet during pregnancy may be putting their children at risk of developing long term, irreversible health issues including obesity, raised levels of cholesterol and blood sugar, according to research published today(1). The study, carried out in rats and funded by the Wellcome Trust, suggests that the effect is even more pronounced in female offspring.
