Switching to new anti-bacterial targets: Riboswitches

...ld of bacterial riboswitches may be a good hunting ground for effective targets against bacterial infection, according to a report by Yale researchers in the journal Chemistry and Biology. Riboswitches are RNA elements that control gene expression in essential metabolic pathways. Researchers in the laborat...

WWF peeks into mysterious life of Borneo's pygmy elephants

...man activity, dubbed Bod Tai, covered a third more ground than did Nancy, who lives in more remote jungle. „X Most of the elephants spend at least some of their time in palm oil plantations or near human habitation, which leads to conflict with people. In recent years, much of the elephants' habitat has bee...

New technique puts brain-imaging research on its head

Researchers and doctors long have relied upon crude approximations made from test dummy crashes or mathematical models that infer ?rather...

NASA's AURA satellite peers into Earth's ozone hole

...how much ozone there is in the atmosphere from the ground to space. The thickness of the Antarctic ozone layer was the third highest of the last decade, as measured by the lowest reading recorded during the year. The level was 102 Dobson Units (the system of measurement designated to gauge ozone thickness)....

Predators keep the world green, ecologists find

...perimeter. There is almost no leaf litter, and the ground is bright red from the subsoil brought to the surface by leaf-cutter ants. "Dead twigs, branches and vine stems from canopy dieback litter the ground, and in places lie in heaps. But in striking contrast with this scenario of destruction, the medium...

"Helping to improve access to environment, health and nutrition information in developing countries is a matter of course for us. We already participate enthusiastically in projects such a...

York researchers develop pollution-busting plants to clean up contaminated land

...ickly enough to stop the contamination of land and ground water. So the York team has redeployed the enzyme in the bacteria into plants, giving them the ability to biodegrade the pollutant more efficiently. Professor Bruce said: "We have taken that activity from the bacteria and put it in plants with large...

Horseshoe crab decline threatens shorebird species

...nergy to complete the trip north to their breeding ground in the Artic. However, due to horseshoe crab's popularity as bait used by fishermen, the crabs appear to be in serious decline. At the same time, there has been a great reduction in the total population of red knots, the report notes. "The number o...

Penguins waddle but they don't fall down, UH researchers say

...guins will travel more than 75 miles across rugged ground terrain to reach their nesting sites. Kurz believes the penguins have learned to use the waddling motion in a way that makes their movements more efficient, adjusting for the limitations of the size of their legs and their weight.
