21st Century grand engineering challenges unveiled

A diverse committee of experts from around the world, convened at the request of the National Science Foundation, announced 14 grand challenges for engineering in the 21st century that, if met, would improve how we live.

All eyes and ears on the corn genome

A consortium of researchers led by the Genome Sequencing Center (GSC) at Washington University in St. Louis, Mo., announced today the completion of a draft sequence of the corn genome.

Reptiles' Muscles Move Lungs for Sneaky Maneuvers in Water

Without a ripple in the water, alligators dive, surface or roll sideways, even though they lack flippers or fins. University of Utah biologists discovered gators maneuver silently by using their diaphragm, pelvic, abdominal ...

Two-Dimensional Fluctuating Superconductivity

Scientists at Brookhaven Lab have discovered a state of two-dimensional (2D) fluctuating superconductivity in a high-temperature superconductor with a particular arrangement of electrical charges known as "stripes."

Compound removes radioactive material from power plant waste

Strontium 90 is a common radioactive by-product of fission in nuclear power plants. When extracted from the reactor along with other isotopes, a mixture is created made up of the radioactive material and inert ions like sodium ...

Meteorites a rich source for primordial soup

The organic soup that spawned life on Earth may have gotten generous helpings from outer space, according to a new study. Scientists at the Carnegie Institution have discovered concentrations of amino acids in two meteorites ...

Carbon nanotubes outperform copper nanowires as interconnects

Researchers at Rensselaer Polytechnic Institute have created a road map that brings academia and the semiconductor industry one step closer to realizing carbon nanotube interconnects, and alleviating the current bottleneck ...

Modeling How Electric Charges Move

Learning how to control the movement of electrons on the molecular and nanometer scales could help scientists devise small-scale circuits for many applications, including more efficient ways of storing and using solar energy. ...
