Intravenous nutrition for critically ill patients must not be administered too early, Belgian study finds (July 1, 2011) -- Intravenous nutrition does not have a positive effect on the recovery of critically ill patients if it is administered early, according to new research from Belgium. Recovery from critical illness is in fact faster when patients receive supplementary intravenous nutrition one week after their admission to intensive care. ... > full story

Money and mimicry: Examining the psychological effect of money and how it affects our behavior and emotions (July 1, 2011) -- We rely on money in our day-to-day life and it is constantly in our minds. After all, money makes the world go round, doesn't it? Now, a new study tries to better understand the psychological effect of money and how it affects our behavior, feelings and emotions. ... > full story

New class of antiangiogenesis drugs: Natural plant compound blocks blood vessel growth by interfering with cellular adhesion (July 1, 2011) -- Researchers have discovered the first of an entirely new class of anti-angiogenesis drugs -- agents that interfere with the development of blood vessels. The investigators describe how a compound derived from a South American tree was able, through a novel mechanism, to interfere with blood vessel formation in animal models of normal development, wound healing and tumor growth. ... > full story

Foot positioning during walking and running may influence ankle sprains (July 1, 2011) -- The position of the foot just before ground contact during running and walking may put people at risk for ankle sprains, according to a new study. ... > full story

HIV-inhibiting mechanism identified (July 1, 2011) -- Researchers have discovered a long-sought cellular factor that works to inhibit HIV infection of myeloid cells, a subset of white blood cells that display antigens and hence are important for the body's immune response against viruses and other pathogens. The factor, a protein called SAMHD1, is part of the nucleic acid sensing machinery within the body's own immune system. ... > full story

Preventing diabetes damage: Zinc's effects on a kinky, two-faced cohort (July 1, 2011) -- In type 2 diabetes, a protein called amylin forms dense clumps that shut down insulin-producing cells, wreaking havoc on the control of blood sugar. But zinc has a knack for preventing amylin from misbehaving. ... > full story

Sound localization at cocktail parties is easier for men (July 1, 2011) -- Differences in male and female behavior are often subject to study. Women are known to be more verbally fluent, have better manual dexterity. Men tend to excel in what are known as visuo-spatial abilities. A new study has demonstrated that men have a similar advantage in their hearing. ... > full story

Scientists use 'optogenetics' to control reward-seeking behavior (July 1, 2011) -- The findings suggest that therapeutics targeting the path between two critical brain regions, the amygdala and the nucleus accumbens, represent potential treatments for addiction and other neuropsychiatric diseases. ... > full story

Electromagnetic fields can disturb learning, study suggests, but only at very high levels (July 1, 2011) -- The effects of high-frequency electromagnetic fields emitted by mobile phones on humans have been hotly debated for years. In a new study, neuroscientists from Germany have shed light on this question. For the first time, they provide evidence that extremely high-powered electromagnetic fields can influence learning processes on the synaptic level within the brain, independent from other factors such as stress. However, such high levels are not encountered during typical use of mobile phones, the researchers note. ... > full story

Babies are specially attuned to our voices and emotions (July 1, 2011) -- Young babies' brains are already specially attuned to the sounds of human voices and emotions, according to a new report. ... > full story

Adult stem cells carry their own baggage: Epigenetics guides stem cell fate (July 1, 2011) -- Adult stem and progenitor cells may not contain a clean genetic slate after all. A new report shows that these cells have unique "epigenetic signatures," which change once a cell differentiates. Epigenetic changes do not affect the make up in a cell's DNA, but how that DNA functions. Epigenetic changes have demonstrated a role in a range of diseases, as well as to be heritable from mother to child. ... > full story
