Cold Fusion Is Hot Again
Presented in 1989 as a revolutionary new source of energy, cold fusion was quickly dismissed as junk science. But as Scott Pelley reports, the buzz now among scientists is that...
Oracle, Sun Now Face Integration Challenge
Through one important piece of corporate computing jargon - "integration" - Oracle has found a justification for its $7.4 billion acquisition of Sun Microsystems. Now it will have to convince...
Atmospheric engineering scheme to combat global warming could diminish solar power
A widely discussed "atmospheric engineering" scheme intended to combat global warming could have unanticipated consequences in reducing the effectiveness of certain kinds of solar power around the Earth, a new...
Bridging the gap in nanoantennas
In a recent publication in Nature Photonics, a joint team of researchers at CIC nanoGUNE, Donostia International Physics Center DIPC, Centro de Física de Materiales of CSIC/UPV-EHU in San Sebastian...

Easier Route To 'Spintronic' Circuits? New Spin Put On Electrons
In the first demonstration of its kind, researchers have controlled the spin of electrons using a ballistic technique -- bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer...
Measuring The Immeasurable: Bond Strength Of Materials Linked To Heat Transfer
The speed at which heat moves between two materials touching each other is a potent indicator of how strongly they are bonded to each other, according to a new study....
ONR demonstrates new counter-mine technology for ships
In a time of increasing irregular warfare threats, the Navy has devised and successfully demonstrated a revolutionary technology to help reduce the risk of naval mine strikes to U.S. Navy...
Smoothing out fluctuations in wind power with "wind"
In reading the current issue of New Scientist, I found a pointer to a blog entry called "Bug eats electricity, farts biogas." Needless to say, I had to learn more.
Team invents first technique for producing promising anti-leukaemia agent
Kapakahines, marine-derived natural products isolated from a South Pacific sponge in trace quantities, have shown anti-leukaemia potential, but studies have been all but stalled by kapakahines' lack of availability...
Important Breakthrough Towards Silicon-based All-optical Integrated Circuits
The first experimental proof of all-optical ultra-fast communication signal processing with silicon-based devices for transmission speeds above 100Gbit/s has been published.
Biocompatible Materials For Rapid Prototyping
