Life cycle assessment essential to nanotech commercial development
03-20-2007 · EurekAlert!Life cycle assessment (LCA) —a cradle-to-grave look at the health and environmental impact of a material, chemical, or product—is an essential tool for ensuring the safe, responsible, and sustainable commercialization of nanotechnology, U.S. and European experts conclude in a new report issued today.

- Adding up renewable energy
08-13-2007 · EurekAlert!
Do the overall efficiencies of renewable energy sources, such as wind, solar and geothermal add up in terms of their complete life cycle from materials sourcing, manufacture, running, and decommissioning? Researchers in Greece have carried out a life cycle assessment to find the answer.

- Trainor Lab characterizes gene essential for prenatal development of nervous system
02-01-2008 · EurekAlert!
The Stowers Institute's Trainor Lab has demonstrated the role of a gene important to the embryonic development of the nervous system, a process that requires coordination of differentiation of immature neural cells with the cycle of cell division that increases their numbers. Until now, the mechanisms regulating these distinct cellular activities have been poorly understood.

- HOXA11 shows its strength in the pelvis
02-14-2008 · EurekAlert!
The quality of life of millions of women is negatively affected by pelvic organ prolapse, which causes symptoms such as urinary incontinence. In women with POP, the main supportive structures of the uterus and vagina, the uterosacral ligaments, are attenuated. Now, mouse studies have shown that the Hoxa11 gene makes a molecular factor essential for USL development, leading to the suggestion that changes in HOXA11-regulated pathways might weaken USLs and thereby cause POP.

- Identified mechanism in the malaria parasite to help it adapt to infected individuals
08-02-2007 · EurekAlert!
Plasmodium falciparum is responsible for the most severe forms of human malaria. Invasion of red blood cells is an essential step of the complex life cycle of this parasite. Alfred Cortés, IRB Barcelona researcher, together with researchers from NIMR, have discovered that the parasite has the ability to switch on and off the expression of some of the proteins it uses to enter its victim's red blood cells.

- Scientists fear rare dolphin driven to extinction by human activities
09-11-2007 · EurekAlert!
An international research team, including biologists from NOAA Fisheries Service, has reported in an online scientific journal that it had failed to find a single Yangtze River dolphin, or baiji, during a six-week survey in China. The scientists fear the marine mammal is now extinct due to fishing and commercial development, which would make it the first cetacean to vanish as result of human activity.

01-11-2008 · EurekAlert!
UCLA researchers have found that a key protein in the body's dendritic cells can stop the virus that causes AIDS from "budding" -- part of the virus' life cycle that is crucial to its ability to replicate and infect other cells.

- Cities incite thunderstorms, researchers find
08-09-2007 · EurekAlert!
Summer thunderstorms become much more fierce when they collide with a city than they would otherwise be in the open countryside, according to research led by Princeton engineers. While thunderstorms are thought of as being purely forces of nature, the Princeton research suggests that man's built environment can radically alter a storm's life cycle.
