Research led by David Litchfield of The University of Western Ontario has identified how biochemical pathways can be "rewired" in cancer cells to allow these cells to ignoresignals that should normally trigger their death. It's one way that cancer cells may become resistant to therapy. The findings are now published in Science Signaling(http://stke.sciencemag.org/cgi/content/full/sigtrans;4/172/ra30 ).

Taiwanese investigators have found that there can be a significantly higher risk of multiple sclerosis (MS) occurring in the year following a shingles, or herpes zoster, attack. The findings, which support a long-held view on how MS may develop, are published in The Journal of Infectious Diseases and now available online (http://jid.oxfordjournals.org/content/early/2011/06/07/infdis.jir239.abstract).
Suffering from parental abuse as a child increases a person's chances of having poor sleep quality in old age, according to a research article in the current issue of the Journals of Gerontology Series B: Psychological and Social Sciences (Volume 66B, Number 3).
Cell phone distractions account for more than 300,000 car crashes each year. As a result, most states have put laws in place to limit or prohibit the use of mobile devices while driving. But a new study led by Temple University finds a widening gap between the evidence on distracted driving and the laws being passed to address the problem.
The new study, published this month in the American Journal of Preventive Medicine, is the first comprehensive collection and coding of state laws attempting to address the public health risk posed by distracted driving.
National Institute of Standards and Technology (NIST) researchers are working to reduce the uncertainty associated with climate-change measurements using a mobile temperature-sensing technology made for tracking delicate or perishable, high-value packages in transit. Developed by international shipper FedEx and tested with help from NIST, the device connects to cell phone networks to provide users with near real-time information on the package's precise location, temperature, humidity, pressure, acceleration, elevation and exposure to light.

Almost universally, red means stop. Red means danger. Red means hot. And after analyzing the results in the 2004 Olympics, a group researchers determined red must mean winning at sports, since athletes wearing red prevailed more often than those wearing blue, especially in hand-to-hand sports like wrestling.
You likely agreed with them until they got to the color red leading to victory stuff, but it's another reason to make fun of evolutionary psychology
A new study from biology researchers at Baylor University and the University of Maryland-Baltimore has found that there are consistent and widespread declines in stream biodiversity at lower levels of urban development more damaging than what was previously believed.
When a person has a family history of cancer, their worry about developing the disease may lead to them refusing to have preventive tests. Advice from genetic counselling units reduces their anxiety but, until now, nobody knew how much. Now, a scientific team has validated the 'Escala de Preocupación por el Cáncer - EPC' (equivalent of the Cancer Worry Scale), the first of its kind in the Spanish language, in order to evaluate it.
The German National Academy of Sciences Leopoldina has submitted an ad-hoc statement on energy research to Prof. Annette Schavan, the German Federal Minister of Education and Research. Against the backdrop of the events in Fukushima, the statement contains twelve key declarations that mainly address research-policy issues connected to the restructuring of Germany's energy system.
PROVIDENCE, R.I. – Researchers from Hasbro Children's Hospital in Providence, R.I., report that medical management may be preferred over surgery for children with orbital cellulitis, an acute infection of the tissues surrounding the eye. They have determined the criteria for surgical intervention should be dependent upon the size of a subperiosteal abscess (SPA). The research is published in the journal Ophthalmic Plastic & Reconstructive Surgery and is now available online in advance of print.
As millions of acres of farmland in the U.S. Midwest and South recover from Mississippi River flooding, scientists report that river flooding can increase levels of potentially harmful flame retardants in farm soils. But the higher levels apparently do not find their way into the milk produced by cows that graze on these lands, according to a study in the ACS journal Environmental Science & Technology.
Antioxidants are popular anti-aging ingredients in skin creams, and now scientists are reporting a new source of these healthful substances — leaf buds of poplar trees. Their study appears in the ACS' Journal of Agricultural and Food Chemistry.
Medical scientists now have "clear" evidence that the damaged cartilage tissue in osteoarthritis and other painful joint disorders can be encouraged to regrow and regenerate, and are developing tissue engineering technology that could help millions of patients with those disorders. That's the conclusion of a new analysis of almost 100 scientific studies on the topic, published in ACS's journal Molecular Pharmaceutics.
Despite years of scientific studies, reports, lawsuits, congressional inquiries, claims and counterclaims, the question of whether bisphenol A (BPA) poses health threats to people lacks a definitive answer, according to a package of articles on the controversial substance in the current edition of Chemical & Engineering News (C&EN), ACS's weekly newsmagazine.
