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

High-resolution imaging expands vision research of live birds of prey (July 23, 2010) -- Bird observatories all over the world may benefit from a newly designed high-resolution imaging system used to study the retinal structure of live birds of prey. Researchers now reveal unprecedented 3-D information about the retina of four species of raptors -- two hawks and two owls -- using the noninvasive, powerful imaging tool. ... > full story

Identification of a gene essential to newborn babies' first breath (July 23, 2010) -- How do mammals prepare themselves in utero for a radical modification to their respiration at the time of birth, when they move abruptly from an aquatic medium to air? Researchers have identified a gene in the mouse that is essential to respiration and consequently to survival at birth. This work opens the way to better understanding respiratory disorders in humans, which can range from sleep apnea to sudden infant death syndrome. ... > full story

European Space Agency develops radar to watch for space hazards (July 23, 2010) -- As part of the European Space Agency's Space Situational Awareness activities, a new radar system will be developed to help safeguard space missions. The radar will detect hazardous objects in Earth orbit and trigger warnings that enable satellite operators to avoid collisions, making spaceflight safer for all. ... > full story

Scientists discover how deadly fungal microbes enter host cells (July 23, 2010) -- A research team has discovered a fundamental entry mechanism that allows dangerous fungal microbes to infect plants and cause disease. The discovery paves the way for the development of new intervention strategies to protect plant, and even some animal cells, from deadly fungal infections. ... > full story

Misuse of anesthesia could cause hepatitis virus transmission (July 23, 2010) -- Hepatitis B virus (HBV) and hepatitis C virus (HCV) can be transmitted during intravenous (IV) administration of anesthesia, according to a new study. ... > full story

Not enough hours in the day for endangered apes: Warming climate may change ape behaviour, resulting in loss of habitat (July 23, 2010) -- A study on the effect of global warming on African ape survival suggests that a warming climate may cause apes to run ‘out of time’. The research reveals that rising temperatures and changes in rainfall patterns have strong effects on ape behavior, distribution and survival, pushing them even further to the brink of extinction. ... > full story

Scientists confirm role for mysterious cell component -- the nucleolinus (July 23, 2010) -- Scientists have confirmed the role in cell division of a long-neglected cellular component, the nucleolinus. The nucleolinus is a structure observed in the nucleus of many cells, including invertebrate egg cells and some mammalian cells. While it was discovered more than 150 years ago, and other scientists have proposed that is involved in cell division, difficulties in visualizing the nucleolinus inside most cells have kept that hypothesis dormant. ... > full story
