PHILADELPHIA (February 2, 2012)— A new study by food safety researchers at Drexel University demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry. The proof-of-concept study was published in the January issue of the Journal of Food Protection.

HUNTSVILLE, Ala. (Feb. 2, 2012) – Two UAHuntsville faculty members from the College of Business were published today in the prestigious journal Science for their investigation of an important issue in research ethics.
AURORA, Colo. (Feb. 2, 2012) – Different kinds of lung cancer behave in different ways, suggesting they are fundamentally different diseases. According to a University of Colorado Cancer Center study published in Cancer, the official journal of the American Cancer Society, different subgroups of non-small cell lung cancer (NSCLC) show distinct patterns of spread in the body.
When a devastating 2004 hurricane wiped out a Caribbean lizard population, University of California, Davis, researchers had an unprecedented opportunity to address a long-simmering controversy in evolutionary biology. Their findings –- from the first experimental study of the so-called "founder effect" in a natural setting -- are published in the Feb. 3 edition of Science Express, the online publication of the journal Science, which will publish the study in print on Feb. 17.
KINGSTON, R.I. – February 2, 2012 – A University of Rhode Island biologist who released lizards on tiny uninhabited islands in the Bahamas has shed light on the interaction between evolutionary processes that are seldom observed.
Jason Kolbe, a URI assistant professor of biological sciences, and colleagues from Duke University, Harvard University and the University of California at Davis, found that the lizards' genetic and morphological traits were determined by both natural selection and a phenomenon called founder effects, which occur when species colonize new territory.
Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how?
Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.
A new study recently published in the Journal of Integrated Pest Management (JIPM) explains the best management practices for consideration and adoption by sod producers in the northeastern U.S.
Durham, NC — Most creatures face compromises when they reproduce — the more energy they devote to having lots of babies, the less they can invest in each one. But do the same tradeoffs hold true for plants? Biologists have long assumed that plants with bigger, showier flowers can make fewer of them per plant. But the data don't always hold up, scientists say. A new study by researchers at the National Evolutionary Synthesis Center may help explain why.
In a recent study led by Uppsala University, the researchers compared the DNA of identical (monozygotic) twins of different age. They could show that structural modifications of the DNA, where large or small DNA segments change direction, are duplicated or completely lost are more common in older people. The results may in part explain why the immune system is impaired with age.
National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of proteins known as phosphodiesterases (PDEs), enzymes that help regulate cell energy.
'Goldilocks' gene could determine best treatment for TB patientsTuberculosis patients may receive treatments in the future according to what version they have of a single 'Goldilocks' gene, says an international research team from Oxford University, King's College London, Vietnam and the USA.
This is one of the first examples in infectious disease of where an individual's genetic profile can determine which drug will work best for them – the idea of personalised medicine that is gradually becoming familiar in cancer medicine.
LA JOLLA, Calif. -- The National Cancer Institute (NCI) estimates that as many as one in 51 men and women will be diagnosed with melanoma—the deadliest form of skin cancer—at some point during their lifetimes. A research team led by Ze'ev Ronai, Ph.D. at Sanford-Burnham Medical Research Institute (Sanford-Burnham) is working to unravel the molecular mechanisms underlying the development and progression of this disease in hopes of improving prevention and treatment strategies.
Investigational urine test can predict high-risk prostate cancer in men who chose 'watchful waiting'
SEATTLE – Initial results of a multicenter study coordinated by researchers at Fred Hutchinson Cancer Research Center indicates that two investigational urine-based biomarkers are associated with prostate cancers that are likely to be aggressive and potentially life-threatening among men who take a "watchful waiting," or active-surveillance approach to manage their disease. Ultimately, these markers may lead to the development of a urine test that could complement prostate biopsy for predicting disease aggressiveness and progression.
A newly available DNA-based prenatal blood test that can identify a pregnancy with Down syndrome can also identify two additional chromosome abnormalities: trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome). The test for all three defects can be offered as early as 10 weeks of pregnancy to women who have been identified as being at high risk for these abnormalities.
NEW YORK – The Wildlife Conservation Society's (WCS) Peru program announced today the discovery of 365 species previously undocumented in Bahuaja Sonene National Park (BSNP) in southeastern Peru.
