Researchers optically levitate a glowing, nanoscale diamond (w/ Video)
(Phys.org) —Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. In a paper published this week in ...
X-ray laser takes aim at cosmic mystery
Scientists have used powerful X-rays from the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory, to study and measure, in atomic detail, a key process at work in extreme plasmas ...

Virtual education... for free
They don't offer degrees but then they don't charge tuition either.
More efficient and reliable robotic-control systems
When a robot is moving one of its limbs through free space, its behavior is well-described by a few simple equations. But as soon as it strikes something solid—when a walking robot's foot hits the ground, ...
US company aims to 'harvest' asteroids
A US company said Tuesday it plans to send a fleet of spacecraft into the solar system to mine asteroids for metals and other materials in the hopes of furthering exploration of the final frontier.
Study: Tigers take the night shift to coexist with people
Tigers don't have a reputation for being accommodating, but a new study indicates that the feared and revered carnivores in and around a world-renowned park in Nepal are taking the night shift to better coexist ...
First photo of shadow of single atom
In an international scientific breakthrough, a Griffith University research team has been able to photograph the shadow of a single atom for the first time.
Scientists create first free-standing 3-D cloak
Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality.
Terminator-style info-vision takes step towards reality
The streaming of real-time information across your field of vision is a step closer to reality with the development of a prototype contact lens that could potentially provide the wearer with hands-free information ...
Team launches world's first ZigBee-based inter-satellite communication system
Engineers at the Nanyang Technological University in Singapore have successfully piloted the world's first ZigBee-based inter-satellite communication system.
Controlling the emission of light? Size matters
In daily life light is often generated by spontaneous emission, for instance, in lighting, in LCD displays, and in DVD players. In this process, an excited quantum emitter, such as an atom, a molecule, or ...
