Microsoft Excel-based algorithm predicts cancer prognosis
Using readily available computer programs, researchers have developed a system to identify genes that will be useful in the classification of breast cancer. The algorithm, described in BioMed Central's open access Journal of Experimental & Clinical Cancer Research will enable researchers to quickly generate valuable gene signatures without specialized software or extensive bioinformatics training.
Study recommends changes to emergency seed aid
A major study of agriculture in Haiti after this year's earthquake has found that much of the emergency seed aid provided after the disaster was not targeted to emergency needs. The report concludes that seed aid, when poorly-designed, could actually harm farmers or depress local markets, therefore hampering recovery from emergencies.
UK: New guidelines to ease sleepless nights
Insomnia and other sleep disorders are very common, yet are not generally well understood by doctors and other health care professionals. Now the British Association for Psychopharmacology (BAP) has released up-to-the-minute guidelines in the Journal of Psychopharmacology, published by SAGE, to guide psychiatrists and physicians caring for those with sleep problems.

Scientific breakthrough to pave the way for human stem cell factories
(PhysOrg.com) -- Large scale, cost-effective stem cell factories able to keep up with demand for new therapies to treat a range of human illnesses are a step closer to reality, thanks to a scientific breakthrough involving researchers at The University of Nottingham.
A single interaction affects the way a child seeks information, study finds
Seven-year-old children only need to interact with a person once to learn who to trust and seek information from, according to a study by Queen's University researchers.
Biochemical pathway may link addiction, compulsive eating
Ezlopitant, a compound known to suppress craving for alcohol in humans, was shown to decrease consumption of sweetened water by rodents in a study by researchers at the Ernest Gallo Clinic and Research Center, which is affiliated with the University of California, San Francisco.
Brain exercises may slow cognitive decline initially, but speed up dementia later
New research shows that mentally stimulating activities such as crossword puzzles, reading and listening to the radio may, at first, slow the decline of thinking skills but speed up dementia later in old age. The research is published in the September 1, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology.
Chip revenue expected to grow 31.5 percent in 2010: Gartner
Worldwide semiconductor revenue is expected to grow 31.5 percent this year to 300 billion dollars, technology research firm Gartner said Wednesday.
Critical polar data flows briskly to researchers
Operation IceBridge -- a NASA airborne mission to observe changes in Earth's rapidly changing polar land ice and sea ice -- is soon to embark on its fourth field season in October. The mission is now paralleled by a campaign to bring data to researchers as quickly as possible and to accelerate the analysis of those changes and how they may affect people and climate systems.
Global Hawk drone aircraft flies over Frank on the GRIP hurricane mission
NASA's 2010 hurricane experiment is in full swing as the tropics have heated up. NASA's Global Hawk unmanned aircraft was sent out over this past weekend to conduct measurements on then Tropical Storm Frank in the eastern Pacific Ocean, the first ever high-altitude flyover of a tropical cyclone with a UAS (unmanned aircraft system).
Highlight: New TB diagnostic proves effective, expedient, study finds
A molecular test designed to easily diagnose tuberculosis (TB) and detect a drug-resistant form of the bacterium that causes TB can provide much more specific, sensitive and rapid results than currently available TB diagnostics, according to a new study in the New England Journal of Medicine.
Hurricane warnings posted on US East Coast, NASA sees Earl's heavy rainfall
NASA's Tropical Rainfall Measuring Mission, or TRMM satellite looked at the rate rain was falling in Hurricane Earl yesterday, and it was intense.
Journal editors question sale of diet pill Meridia
(AP) -- Editors of a top medical journal are questioning whether the diet pill Meridia should stay on the market even if it's restricted to people without heart disease.
Kids with sports concussions need time out
Between 1997-2007, the number of emergency room visits for concussions doubled in children ages 8-13 who play organized sports. Part of the reason is greater awareness, according to Mark E. Halstead, MD, assistant professor of orthopaedic surgery and of pediatrics and director of Washington University in St. Louis` Sports Concussion Program.
Lower blood pressure goal benefits some African-Americans with chronic kidney disease
On average, a lower blood pressure goal was no better than the standard blood pressure goal at slowing progression of kidney disease among African-Americans who had chronic kidney disease resulting from high blood pressure, according to results of the African-American Study of Kidney Disease and Hypertension (AASK), the largest and longest study of chronic kidney disease (CKD) in...
NASA infrared data sees convection building in Fiona's clouds
Infrared satellite imagery from NASA's Aqua satellite showed some strong convection building in Tropical Storm Fiona, and her maximum sustained winds increased from 40 mph yesterday to 60 mph this morning
Neonatal intensive care units critical to infant survival
Very low birthweight and very preterm infants are more likely to die if they are not born at hospitals with neonatal intensive care units specially equipped to care for seriously ill newborns, in contrast to similar babies born at those specialized facilities.
Recipe for water: Just add starlight
ESA's (European Space Agency) Herschel infrared space observatory has discovered that ultraviolet starlight is a key ingredient for making water in the atmosphere of some stars. It is the only explanation for why a dying star is surrounded by a gigantic cloud of hot water vapour. These new results will be published tomorrow in Nature.
Researchers receive largest single collection of psoriasis DNA samples
Millions of Americans struggling with psoriasis and psoriatic arthritis are one step closer to a cure with the release of the first National Psoriasis Victor Henschel BioBank DNA samples for use in research at the University of Michigan Health System; research that hopes to uncover the unknowns about the genetics of psoriasis and psoriatic arthritis.
Sensor measures yoctonewton forces fast
(PhysOrg.com) -- Physicists at the National Institute of Standards and Technology have used a small crystal of ions (electrically charged atoms) to detect forces at the scale of yoctonewtons. Measurements of slight forces -one yoctonewton is equivalent to the weight of a single copper atom on Earth -- can be useful in force microscopy, nanoscale science, and tests of fundamental physics theories.
Spectrum of young extrasolar planet yields surprising results
(PhysOrg.com) -- Astronomers at the University of Hawaii have measured the temperature of a young gas-giant planet around another star using the W. M. Keck Observatory, and the results are puzzling. They have found that its atmosphere is unlike that of any previously studied extrasolar planet.
