Potential Key To Curing Tuberculosis
04.10.2009 17:00 36 views 0 comments
Researchers have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system. They have also found a method to possibly neutralize that enzyme, which may someday lead to a cure for tuberculosis -- a contagious disease that kills 1.5 to 2 million people worldwide annually.

If the climate is not quite right, birds will up and move rather than stick around and sweat it out, according to a new study. The findings reveal that most of the bird species studied in California's Sierra Nevada mountains have adjusted to climate change over the last century by moving to sites with the temperature and precipitation conditions they favored.

New Electronic Concept: How Hybrid Motors Could Become Cheaper
04.10.2009 17:00 33 views 0 comments
Not all that long ago, hybrid vehicles were still really exotic. Now, you see them more and more frequently on our roads. However, hybrid cars are not mass-produced as their production costs are still relatively high. A researcher has now developed a new concept that integrates power electronic functions and an electric motor, which could reduce the costs of producing hybrid cars. Read more »

New Mathematical Model Suggests How The Brain Might Stay In Balance
04.10.2009 17:00 35 views 0 comments
The human brain is made up of 100 billion neurons -- live wires that must be kept in delicate balance to stabilize the world's most magnificent computing organ. Too much excitement and the network will slip into an apoplectic, uncomprehending chaos. Too much inhibition and it will flatline. A new mathematical model describes how the trillions of interconnections among neurons could maintain a stable but dynamic relationship that leaves the brain sensitive enough to respond to stimulation without veering into a blind seizure.

New Approach To Targeting The Hidden Reservoir Of HIV
04.10.2009 11:00 37 views 0 comments
The drugs used to treat individuals infected with HIV-1 keep the virus under control but do not eliminate it from the body, some remains hidden in immune cells known as resting CD4+ T cells. However, researchers have now developed an in vitro system that faithfully mimics the situation in people and used it to identify a compound that can get at this hidden HIV-1 and eliminate it from the cells.

Inventors Offer Ecofriendly Substitutes For Polystyrene
04.10.2009 11:00 32 views 0 comments
Rigid, custom-fit foam pieces like those that keep computer monitors firmly in place inside cardboard boxes during shipping could be made with eco-friendly starch from potatoes, wheat or corn, instead of from petroleum, according to a research plant physiologist. Opting for starch in place of petroleum-derived polystyrene would lessen America's dependence on petroleum. Read more »

Scientists have shown that, in ancient times, the Earth's magnetic field was structured like the two-pole model of today, suggesting that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate. The findings may lead to a better understanding of historical continental movement, which relates to changes in climate. Read more »
