...re to ozone is necrosis, or cell death, with brown spots marring plant leaves. But in some areas of metropolitan New York City, as well as in other polluted cities, Gregg and her colleagues have found "footprints" of lower-than-expected ozone exposures.

...Infrared Detection) satellite to chart thermal hot spots within a 190 km strip of land during the satellite's four-minute pass over the Spanish province. Once the satellite acquired the data it was downlinked to ESA's Villafranca tracking station near Madrid, then transferred to the German Aerospace Centre...... yielded the same specific mutational hot and cold spots along DNA strands that are observed in human antib.... In fact, the experiment yielded 14 out of 15 hot spots with perfect DNA sequences, demonstrating that the mutation process had gone off without a glitch.

...of stimulation, a nerve cell will pull the binding spots for glutamate into the cell, weakening its connections and ending the "conversation." For 40 years, enzymes known as protein kinases, which modify other proteins, have been known to be involved in nerve cells' ability to "unplug the phone" -- long t...Widespread cannibalism may have caused prehistoric prion disease epidemics, Science study suggests
... E219K variations, even when the sequence at other spots was highly variable, indicated that the variations were ancient--more than 500,000 years old, according to authors' estimates. Finally, the researchers identified a telltale signature of balancing selection in the gene: a greater than average number ...New book entertainingly tells 'What Good Are Bugs'
... After finding a leaf with many shiny, glimmering spots full of stuck insects, his high-school biology teacher in Connecticut explained that it was one of 90 known species of sundews, a plant that traps and eats insects. Charles Darwin also had described sundews a century earlier. Another more recent pers...Tufts environmental engineers tackle destructive nutrients in nations waterways
