UBC researchers find new superbug weapon for near-empty antibiotics arsenal
...when the immune system is stimulated and, in fact, actually reduced the potentially harmful septic response. Sepsis, a consequence of a ravaging inflammatory response associated with infection, kills as many as 200,000 annually. The innate immune response is the first line of defense against infection and ...No pain, DOE Joint Genome Institute gains coveted ergonomics prize with 'Shake 'N Plate'

The "Shake 'N Plate" upstaged such big names in the competition as Boeing, GE, Harley Davidson, and Toyota, to take home the prize.

...ng methods detect only a small fraction of what is actually in the air, said Timothy Buckley, the study's senior author and an associate professor of public health at Ohio State. And what they detect is often so damaged due to the collection method that the pathogens no longer possess the same infectious ...Volcanic plumbing dictates development of deep-sea hydrothermal vents
...mey said, the deeper ridge is magmatically active, actually producing the same or more magma but not as surface eruptions. Instead, the magma is cooled at depth or intruded. At both places, the plates are spreading apart at the same rate, Toomey said. The deeper areas look older on the surface, like they are ...Winner of Tyler Environmental Prize announced

In addition, the method yields much less residue than traditional wastewater treatment, while processing 10 to 20 times as much waste.

In a 2004 study, Daly and colleagues found that resistant and sensitive bacterial cells had significantly different metal concentrations, pointing to high levels of manganese and low iron levels as possible influences...Other highlights from the March 21 JNCI

By offering them a choice between normal wooden blocks and specially designed blocks made of wood and other materials, the researchers found that the termites always ...Do you need sex to be a species?
