- Circulation of LHC Beams Could Resume in Earnest over the Weekend (Fri Nov 20 2:50 pm)
The Large Hadron Collider , the world's most powerful particle accelerator, is drawing near to its long-awaited reboot. More than a year after the European collider's initial start-up was quashed by a helium leak caused by a faulty... - Novel Nova: Stellar Blast Powered by Helium May Leave a Tantalizing Remnant (Fri Nov 20 1:05 pm)
A stellar explosion known as a nova that was detected in 2000 formed a two-lobed shell of material ejected from the star. Shaped like a bow tie, it continues to swell at great velocity. But, curiously, the coat of ejecta flowing outward from... - Illuminating the Lilliputian: 10 Bioscapes Photo Contest Winners Revealed (Wed Nov 18 12:31 pm)
We are approaching the millennial anniversary of the first meaningful written description of how lenses and light could be used to magnify objects. It was in 1011 that Arab scientist Ibn al-Haytham (Alhazen) began writing the Book of Optics... - Ultrathin, Now Ultraflat: Ripple-Free Graphene May Hold Key to Material's Mysteries (Wed Nov 18 12:01 pm)
Graphene has been a hot topic in physics and materials science since its discovery five years ago . The sheets of carbon, just an atom thick, have a host of intriguing properties , including transparency, strength and a structure that lets... - Nanodevices Bend under the Force of Light (Sun Nov 15 12:01 pm)
A team of researchers has fabricated a micron-scale device that deforms significantly under the force of light, a technology that could form the basis for tiny light-actuated switches or filters in future optical devices. [More] ...
