Nano Sculptures In Gold
If someone is charged up, the color of their face might change, but they don’t immediately pull off one of their arms, only to reattach it as a third leg....
Superfluid-superconductor relationship detailed
Scientists have studied superconductors and superfluids for decades. Now, researchers have drawn the first detailed picture of the way a superfluid influences the behavior of a superconductor. In addition to...
Invisible Bullet-Tagging Technology Could Deter Criminals
Gun-slinging evil-doers beware. Scientific justice is just around the corner thanks to a new nanotechnology system that not only better captures DNA on guns, but attaches hard-to-remove, microscopic tags to...
X-ray Diffraction Looks Inside Aerogels In 3-D
The first high-resolution x-ray diffraction imaging of an aerogel, performed at beamline 9.0.1 of the Department of Energy's Advanced Light Source at Lawrence Berkeley National Laboratory, has revealed the aerogel's...
China Becomes A Physics Powerhouse
Judged by the astonishing increase in journal papers written by scientists in China, there can be little doubt that China is finding its place as one of the world's scientific...
Brightest, Sharpest, Fastest X-ray Holograms Yet
An international group of scientists working at the Advanced Light Source (ALS) at DOE's Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg, Germany, has produced two...

Telescope Embedded In Glasses Lens Promises To Make Driving Easier For Visually Impaired
Glasses embedded with a telescope promise to make it easier for people with impaired vision to drive and do other activities requiring sharper distance vision. Scientists have found advantages of...
Nanosilver products raise concerns of safety, effectiveness
Little is known about how the minuscule particles of silver affect humans or even if nanosilver's antibacterial claims hold up. ...
Can a Nuclear Blast Alter Earth's Rotation?
Nuclear bombs are humankind's most powerful weapon, but their destructive impact would unlikely alter the spinning of the Earth on its axis.
Nanotechnology: Size-specific Cracking Shakes
Certain sizes of nanostructures may be more susceptible to failure by fracture than others. As the size of a structure gets to the nanoscale, atomic vibrations (also known as phonons)...
U.S. border agents given power to seize travellers' laptops, cellphones
U.S. authorities now have the power to seize travellers' electronic devices, including laptops and cellphones, and make copies of their contents at an off-site location.
Siemens builds a lock made of light: Data transfer using quantum cryptography
Electronic communication is becoming more secure all over the world. Siemens IT Solutions and Services, Austrian Research Centers (ARC) and Graz University of Technology have joined forces to develop the...
