More than 1,500 high school students from Ohio, Florida, Indiana, Maryland, New York, Pennsylvania and Wisconsin will compete in the ninth annual FIRST Buckeye Regional Robotics Competition for regional awards and an opportunity to advance to the FIRST Championship competition.

The authors highlight analyses showing that since 2002, deforestation in the Brazilian Amazon has been 7 to 11 times lower inside of indigenous lands and other protected areas than elsewhere. Simulation models suggest that protected areas established between 2003 and 2007 could prevent an estimated area of 100,000 square miles of deforestation through 2050.

This will be the first time an advanced biofuel has been used in the Shell V-Power race fuel used by technical partner Ferrari, in Formula One.

Like a band of detectives surveying the movement of a criminal, researchers using photographic technology have caught at least one culprit in the act. In this case, electron microscopy was used to watch a deadly bacteria breakdown cell walls in wine grape plants – an image that previously had not been witnessed.

The vineyard consists of double cordon espaliered Tempranillo vines. Two typical soils of Rioja Alavesa region were identified: sloping soil with an average depth of 70 cm and very exposed to erosion and flat soil with an average depth of 150 cm that tends to accumulate soil eroded from the slopes.

The public can follow along with NASA on its journey of lunar discovery. On March 15, the publicly accessible Planetary Data System will release data sets from the seven instruments on board NASA's Lunar Reconnaissance Orbiter.

Thomas D. Kirsch, M.D., M.P.H., writes in the essay that the team of Johns Hopkins physicians that he lead in Haiti for two weeks soon after the earthquake had to quickly adjust standards of care that are common in the United States due to the sheer volume of patients, the wide range of injuries and complaints, and inadequate medical resources

We are proud to be able to announce the launch of this state-of-the-art plant in Johannesburg,” said Steve Harrison, Head of Specialty Gases and Specialty Equipment, Linde. “Africa is an important growth market for our HiQ® specialty gases business and getting our production and supply capabilities nearer to our customers is critical to achieving this growth.

Westmont, NJ, HVP, or hydrolyzed vegetable protein, has made the front page of news outlets across the country over the last few days.A Nevada food manufacturer that supplies HVP as a basic ingredient for other processed food manufacturers has come under the U.S. Food and Drug Administration’s (FDA) scrutiny after a shipment tested positive for Salmonella.

For T cells to detect and kill foreign pathogens such as clumps of bacteria or viruses, the cells must first be ‘triggered’ into action and ‘transform’ from inactive and harmless immune cells into killer cells that are primed to seek out and destroy all traces of a foreign pathogen.

A team of scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say.

Most polymers — materials made of long, chain-like molecules — are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator.

The study, based on a database of more than 200,000 Quebec residents aged 65 and older, showed statistical relationships between a diagnosis of cataracts or cataract surgery and the class of drugs called selective serotonin reuptake inhibitors (SSRIs), as well as between cataracts and specific drugs within that class.
