Diatom genome reveals key role in biosphere's carbon cycle

...ould like to better understand how these organisms react to changes in sea temperatures, the amount of light penetrating the oceans, and nutrients. "Oceanographers thought we understood how diatoms use nitrogen, but we discovered they have a urea cycle, something no one ever suspected," Armbrust says. A u...

Studying the chemistry of drugs in wastewater

...studying what happens to pharmaceuticals when they react with chlorine--a disinfectant commonly used in wastewater treatment. Scientists around the world often find drugs in water samples taken from streams and other waterways, but little is known about byproducts of those drugs created during chlorine tre...

...ress, caused by products of oxygen metabolism that react with and damage cellular components like proteins and DNA. In a second paper, they link DJ-1 dysfunction to the aggregation of alpha-synuclein, a hallmark of Parkinson's neuropathology. Oxidative stress has long been associated with neuronal cell ...

After flu exposure, mild exercise protects mature mice from dying

...d, exercise was stopped, to mirror how most people react once they come down with flu-like symptoms. The mice were nave, that is, they previously hadn't been exercising on a regular basis. Results both striking and surprising; human flu vaccine reaction study underway 20-week-old mice that had exercised ...

New risks for bladder cancer identified by MIT team

...years ago. Arylamines to which a person is exposed react with a protein in the blood, resulting in specific products that can be detected and measured via mass spectrometry. "So what popped out of this was actually pretty startling," Tannenbaum said. "Three of the nine compounds were indeed found...

US DHS sponsored evaluation confirms superior performance of Response Biomedical's RAMP anthrax test

... in evaluations to confirm that it would not cross react with non-Bacillus anthracis bacteria. To judge the accuracy of the data generated, AOAC organized 12 laboratories nationwide to assess RAMP's performance using identical samples. The RAMP test performed well in the collaborative study, and little v...

Ground-level ozone linked to increased mortality

...missions from cars, power plants and other sources react chemically to sunlight. Stratospheric ozone, which is higher in the atmosphere, is the "ozone layer" that protects the Earth from ultraviolet radiation. "This is one of the largest ozone pollution studies ever conducted," said lead author Michelle Be...

Diamonds are a urologist's best friend

...of diamond-like carbon. DLC-coated surfaces do not react chemically with their environment; they are hardwearing, can be sterilised and reduce friction. Even after three months in the body the coated stents show virtually no incrustation,' says Dr. Andreas Meiner, Urological Resident Physician at Bonn's Un...

Purdue researchers align nanotubes to improve artificial joints
