Microbicide containing engineered bacteria may inhibit HIV-1 (July 24, 2010) -- Researchers from the U.S. and abroad used bacteria inherent to the human vaginal tract to develop a live, topical microbicide that may induce production of HIV-1 protein inhibitors and ultimately prevent transmission of the virus. ... > full story

Virtual reality gives insight on protein structures (July 24, 2010) -- To understand a protein, it helps to get inside of it, and a professor has now figured out a way to do so. A new computer software program and projection system lets a person look at larger-than-life, 3-D structures of proteins in virtual reality. This allows scientists to walk inside, through or around the protein of interest for investigating its structure and function. ... > full story

Chokeberry extract found to regulate weight gain, blood glucose, and inflammation in rats (July 24, 2010) -- A new study finds that chokeberry extract inhibits weight gain in insulin-resistant animals and modulates multiple genes associated with adipose tissue growth, blood glucose regulation, and inflammatory pathways. ... > full story

Asia's most devastating droughts reconstructed (July 24, 2010) -- Asia's monsoon rains feed nearly half the world's population. A new study of tree rings provides a detailed record of at least four epic failures of the monsoon that have shaken Asia over the last thousand years. The study is expected not only to help historians understand how environment has affected the past, but to aid scientists trying to understand the potential for large-scale disruptions in the face of changing climate. ... > full story

Cold-blooded mothers: Magpie parents seem to induce mortality of 'unwanted' chicks (July 24, 2010) -- A new pattern of nestling mortality was found in magpies' nests. Sons died more in the nests with more daughters and daughters died more in the nests with more sons. Researchers think that this pattern, that reinforces the original bias in brood sex composition, implies parental strategies being set as a "package," where specific initial sex composition of a brood is correlated with a specific parental "attitude" towards sons and daughters. ... > full story

Diabetes monitoring device benefits not just people but dogs and other animals, too (July 24, 2010) -- A researcher is using a continuous glucose monitoring device -- commonly used in humans with diabetes -- to help treat dogs and other animals. The device, which provides a detailed glucose picture of an animal over several days, will help pet owners manage their pets' diabetes. ... > full story

Hops helps reduce ammonia produced by cattle (July 24, 2010) -- An agricultural scientist may have found a way to cut the amount of ammonia produced by cattle, using a key ingredient of the brewer's art: hops. ... > full story

Cancer-metabolism link runs deep in humans, novel network algorithm suggests (July 23, 2010) -- Eighty years ago, the medical establishment believed cancer was caused by a dysfunction of metabolism, but the idea went out of vogue. Now, scientists are again looking at metabolism and its role in cancer and other common diseases. ... > full story

Supercomputer reproduces a cyclone's birth, may boost forecasting (July 23, 2010) -- Scientists have employed NASA's Pleiades supercomputer and atmospheric data to simulate tropical cyclone Nargis -- with the first model to replicate the formation of the tropical cyclone five days in advance. ... > full story

Medicine from moss: Bioreactor technique may offer hope to people with age-related blindness (July 23, 2010) -- Biologists in Germany have used a moss bioreactor to produce a human protein, the absence of which leads to age-related blindness in 50 million people. ... > full story

White eyes, foot-wide flowers, maroon plants: Researcher creating unique winter-hardy hibiscuses (July 23, 2010) -- With a little cross-breeding and some determination, plant physiologist and forage agronomist Dr. Dariusz Malinowski is trying to add more colors to the world of hibiscuses. Malinowski is working on breeding winter-hardy hibiscus in what started as a hobby about four years ago, but in the last year has been added to the strategic plan of the Vernon research program. ... > full story

How do cells die? Biophotonic tools reveal real-time dynamics in living color (July 23, 2010) -- Apoptosis, programmed cell death, is essential to normal development, healthy immune system function, and cancer prevention. The process dramatically transforms cellular structures but the limitations of conventional microscopy methods have kept much about this structural reorganization a mystery. ... > full story
