Scientists create invisible objects without metamaterial cloaking
Moscow, Russia (SPX) Apr 15, 2015 -
Physicists from ITMO University, Ioffe Institute and Australian National University managed to make homogenous cylindrical objects completely invisible in the microwave range. Contrary to the now prevailing notion of invisibility that relies on metamaterial coatings, the scientists achieved the result using a homogenous object without any additional coating layers. The method is based on a new u ...

On the road to spin-orbitronics
Berkeley CA (SPX) Apr 15, 2015 -
Few among us may know what magnetic domains are but we make use of them daily when we email files, post images, or download music or video to our personal devices. Now a team of researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has found a new way of manipulating the walls that define these magnetic domains and the results could one day rev ...

NIST tightens the bounds on the quantum information 'speed limit'
Washington DC (SPX) Apr 15, 2015 -
If you're designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but physicists at the National Institute of Standards and Technology (NIST) have narrowed the theoretical limits for where that "speed limit" is. The research implies that quantum processors will work more slowly than some resear ...

Graphene pushes the speed limit of light-to-electricity conversion
Madrid, Spain (SPX) Apr 15, 2015 -
The efficient conversion of light into electricity plays a crucial role in many technologies, ranging from cameras to solar cells. It also forms an essential step in data communication applications, since it allows for information carried by light to be converted into electrical information that can be processed in electrical circuits.
Graphene is an excellent material for ultrafast conver ...

A glass fiber that brings light to a standstill
Vienna, Austria (SPX) Apr 15, 2015 -
Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place. A team of scientists at the Vienna University of Technology has now demonstrated that this problem can be solved - not only in strange, unusual quantum systems, but in the glass fiber networks we are already using today.
By co ...

Unravelling relativistic effects in the heaviest actinide element
Mainz, Germany (SPX) Apr 12, 2015 -
An international collaboration led by the research group of superheavy elements at the Japan Atomic Energy Agency (JAEA), Tokai, Japan has achieved the ionization potential measurement of lawrencium (element 103) with a novel-type technique at the JAEA tandem accelerator.
Based on the empirically developed "actinide concept", and in agreement with theoretical calculations, in today's Perio ...

Romania 'Agression Platform' Against Russia With US Missile Defense Systems
Moscow (Sputnik) Apr 12, 2015 -
Alexander Mosesov - The planned deployment of the shore-based Aegis command and control component of the US Ballistic Missile Defense (BMD) system in Romania is turning the country into a platform for aggression against Russia, leader of the National-European Communitarian Party (NCP) told Sputnik on Tuesday.
According to the US Missile Defense Agency, the United States will install an Aeg ...
