Magnetic logic advances
Magnetic memory chips, which retain data after the power is turned off, are becoming available and could eventually supplement or even replace disk drives in computers. Several research teams are looking to take this technology beyond simply storing data by using it in computer chips that process data...

Seeing the light of Net access
High-speed Internet access and wireless home networks are widespread technologies, and researchers are working to make them faster and cheaper...

Carbon gets more hydrogen
Hydrogen is a clean-burning fuel, but using it as an environmentally friendly energy source requires finding clean ways to produce it. One of the most promising approaches is solar water-splitting, a scheme to use sunlight to drive the chemical separation of hydrogen and oxygen from water

Chemistry pumps artificial muscle
Much of the research into artificial muscle involves using electricity or temperature to change the shape of polymer materials. A major aim of this research is to use these materials to someday power machines like robots

Bits and pieces
A bacterial product slows light, dead bacterial bodies pump fluids, and nanoscale light promises to speed supercomputers.


View from the High Ground: Cornell's Jon Kleinberg
Six degrees of separation, buying gasoline by the molecule, the science of popularity, all just getting along online, intellectual prosthetics, Big Science, making up questions, and telling stories.

How It Works: Quantum computing: qubits
Photons, electrons and atoms, oh my! These particles are the raw materials for qubits, the basic building blocks of quantum computers.

Pigs in space

Although the latest news on tipping points is about global warming, it looks like we have another pollution-related tipping point to contend with -- artificial debris in Earth orbit.

A study by NASA scientists shows that if no spacecraft were launched after December 2004, collisions among satellites, rocket parts and fragments thereof -- numbering more than 9,000 -- will produce more fragments, adding objects in low Earth orbit

Dangerous thoughts ahead

"In most areas of science and technology, the origins of new breakthroughs can still be found in the work of a small number of people -- or even a single person -- working at their own pace on their own questions, pursuing things that interest them. "
- Jon Kleinberg, Cornell University
