Putting A Price Tag On Pollution

.... Forexample, a city may decide to give a proposed factory a break on pollution feesif it is likely togenerate a lot of new tax revenue. "My method makes predictions about the physical fate of ground pollution,"the Hopkinsengineer says. "But there are other factors that ought to be considered, such ast...

Vertex Pharmaceuticals/Yale Research Team Uses Gene Knockout Mice To Establish Role Of Caspase-9 In Neuronal Cell Death Pathway

...d human caspases. "When mitochondria -- the energy factory of cells -- are damaged, Caspase-9 isactivated leading to cell death," said Dr. Richard A Flavell, an HHMIInvestigator and an author of the study. "In cells lacking Caspase-9, thisdamage did not give rise to cell death." "Our results also indicate t...

Bacteria That Gorge On Rotting Waste Can Break Down DDT

...s. In a year-long test at an old pesticide factory in Tampa, Florida,AstraZeneca's process, called Xenorem, cut DDT levels in the soil by more than95 per cent. DDT is considered one of the worst pollutants because its breakdownproducts, such as DDE, were thought to be almost indestructible. But recen...

Successful 'Green' Solvent Found For Problematic Chemicals

...Becausethe solvents evaporate easily into the air, factory workers may inhale them. Additionally, the solvents add to damage of the earth's atmosphere, becauseorganic solvents eventually will oxidize and create carbon dioxide, a greenhouse gas with potential impact on global warming. In recent years,...

UCSC researchers obtain first detailed images of a complete ribosome

...action. Cate compared the ribosome to a miniature factory where proteins are made on anassembly line. "To a large extent it has been a mystery how this assembly lineis laid out, and these papers show where different pieces of equipment are onthe shop floor," he said. Biologists have known the basic outlines...

Researchers find new mechanism for growing new blood vessels

...by blocking the cell's central protein-degradation factory known as a proteasome, an organized collection of cellular proteases, which would otherwise break down HIF-1alpha. "Unlike the other available proteasome inhibitors, PR39 appears to be fairly selective for HIF-1alpha, thereby likely minimizing side e...

Treated with adhesion molecules, the robot's fingers might select particular cells or bacteria from a sample, or they might support surgical procedures. In addition, the Science authors say, an array of microrobots could simultaneously han...

High-resolution image illuminates catalytic engine of the ribosome
