On Wednesday, NASA and IBM announced the agency has selected an IBM System p575+ supercomputer for evaluating next-generation technology to meet the agency's future supercomputing requirements. Supercomputers play a critical ...

Excitons play peek-a-boo on carbon nanotubes

In the quantum world, photons and electrons dance, bump and carry out transactions that govern everything we see in the world around us. In this week's issue of Science, French and U.S. scientists describe a new technique ...

Agonized pose tells of dinosaur death throes

The peculiar pose of many fossilized dinosaurs, with wide-open mouth, head thrown back and recurved tail, likely resulted from the agonized death throes typical of brain damage and asphyxiation, according to two paleontologists.

Birds, Bees, and Moths Drive Flower Evolution

Flowers evolve in a predictable fashion to match the mouthparts of pollinating birds and insects, rather than engaging in a gradual "arms race" between flower and pollinator, according to a new study by researchers at the ...
