Synthetic biomaterials mimic cellular membranes: Use in nanomedicine, drug delivery (May 23, 2010) -- An international collaboration led by chemists and engineers has prepared a library of synthetic biomaterials that mimic cellular membranes and that show promise in targeted delivery of cancer drugs, gene therapy, proteins, imaging and diagnostic agents and cosmetics safely to the body in the emerging field called nanomedicine. ... > full story
Gene therapy may be effective in treating pulmonary arterial hypertension (May 23, 2010) -- Gene therapy has been shown to have positive effects in rat models of pulmonary arterial hypertension (PAH), according to researchers at the University of Adelaide in Australia. ... > full story
Schooling fish offer new ideas for wind farming (May 23, 2010) -- The quest to derive energy from wind may soon be getting some help from a fluid-dynamics expert -- and a school of fish. ... > full story
Neuromuscular electrical stimulation reduces muscle atrophy in COPD, researchers find (May 23, 2010) -- Neuromuscular electrical stimulation (NMES) may reduce muscle atrophy in patients with severe chronic obstructive pulmonary disease (COPD), according to Canadian researchers. ... > full story
Enabling video systems to react intelligently to content (May 23, 2010) -- Highly sophisticated video-content analysis now makes possible fast and reliable diagnosis of pulmonary embolisms, automatically detects threatening situations in surveillance scenarios and can provide more enjoyable and customized home entertainment. The systems achieve this by reacting not only to the contents of the data but also to the context. Commercial applications are already developing across Europe. ... > full story
Arizona's smoking ban reduced hospital visits (May 23, 2010) -- Since the 2007 state law that bans smoking in public venues took effect, admissions for ailments related to secondhand smoke have declined by as much as 33 percent. ... > full story
Invention regulates nerve cells electronically (May 22, 2010) -- A major step toward being able to regulate nerve cells externally with the help of electronics has been taken by researchers in Sweden. The breakthrough is based on an ion transistor of plastic that can transport ions and charged biomolecules and thereby address and regulate cells. ... > full story
Prenatal exposure to endocrine-disrupting chemicals linked to breast cancer (May 22, 2010) -- A study in mice reveals that prenatal exposure to endocrine-disrupting chemicals, like bisphenol-A (BPA) and diethylstilbestrol (DES), may program a fetus for life. Therefore, adult women who were exposed prenatally to BPA or DES could be at increased risk of breast cancer, according to a new study. ... > full story
Gesture-based computing on the cheap: Multicolored gloves making Minority Report-style interfaces more accessible (May 22, 2010) -- Ever since Steven Spielberg's 2002 sci-fi movie Minority Report, in which a black-clad Tom Cruise stands in front of a transparent screen manipulating a host of video images simply by waving his hands, the idea of gesture-based computer interfaces has captured the imagination of technophiles. Researchers have now developed a system that could make gestural interfaces much more practical. Aside from a standard webcam, like those found in many new computers, the system uses only a single piece of hardware: a multicolored Lycra glove that could be manufactured for about a dollar. ... > full story
Exercise may keep cancer patients healthier during, after treatment (May 22, 2010) -- Breast and prostate cancer patients who regularly exercise during and after cancer treatment report having a better quality of life and being less fatigued, according to researchers. ... > full story
Breaking the logjam: Improving data download from outer space (May 22, 2010) -- Space satellites that detect nuclear events and environmental gasses face a data logjam because their increasingly powerful sensors produce more information than their bandwidth can easily transmit. Experiments at the International Space Station indicate that sending more complex computer chips into space to pre-reduce the large data stream sent Earthbound could be the answer. But how well would the latest, most sensitive computing electronics fare in the harsh environment of outer space? ... > full story
Meaner than fiction: Reality TV high on aggression, study shows (May 22, 2010) -- Researchers looked at five reality shows and five non-reality shows and found 52 acts of aggression per hour on reality TV compared to 33 per hour for the non-reality programs. ... > full story
