Penn paleontologists locate a new genus of colossal dinosaur along an ancient coastline
...ng through an ancient mangrove forest, Paralititan breaks significant new ground for paleontologists. "While now arid, the Bahariya Oasis some 180 miles southwest of Cairo, where we found the dinosaur, was apparently more like the Florida Everglades during the Late Cretaceous Period," Smith said.

...than do younger nurse bees. AChE is an enzyme that breaks down a primary neurotransmitter known as acetylcholine (ACh). Neurons use ACh to communicate with one another. In the human body, ACh signals muscle movement, and, in the brain, it is linked to learning and memory. In many Alzheimers patients, res...Researchers uncover a piece of nature's secret nitrogen formula
...t to see how this enzyme goes to the next step and breaks that bond," says Holland. Knowing how Nature so easily pulls nitrogen from the atmosphere may lead to a better understanding of how the ecology may balance itself, and may eventually provide a safer, more economical method of nitrogen fixing for the ...... that cooks it. Ultraviolet radiation from the sun breaks down DNA. Different materials absorb and radiate light at different wavelengths.

...b, tested a repair process that fixes DNA that has breaks in both strands. Normally a matching set of two strands, DNA may be irreparably damaged if both strands break in the same area. By adding what would seem to be "broken" DNA to the yeast, the scientists tested the mutants' abilities to fix these bre...Microbe first to break down PCBs
