Researchers at the Niels Bohr Institute have combined two worlds – quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new coo

University of Notre Dame nuclear physicists Philippe Collon and Michael Wiescher are using accelerated ion beams to pinpoint the age and origin of material used in pottery, painting, metalwork and other art. The results of their tests can serve as powerful forensic tools to reveal counterfeit art work, without the destruction of any sample as required in some chemical analysis.

The first systematic power profiles of microprocessors could help lower the energy consumption of both small cell phones and giant data centers, report computer science professors from The University of Texas at Austin and the Australian National University.

Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. They have performed an experimental demonstration of quantum computation in which the input, the data processing, and the output remain unknown to the quantum computer. The in

Designing an all-terrain robot for search-and-rescue missions is an arduous task for scientists. The machine must be flexible enough to move over uneven surfaces, yet not so big that it's restricted from tight spaces. It might also be required to climb slopes of varying inclines. Existing robots can do many of these things, but the majority require large amounts of energy and are prone to overheat

Researchers have created new "microtweezers" capable of manipulating objects to build tiny structures, print coatings to make advanced sensors, and grab and position live stem cell spheres for research.

Technology has grown by leaps and bounds, yet are computers helping students progress in their learning? Absolutely, says a 40-year retrospective on the impact of technology in classrooms.

Scientists from IBM and the German Center for Free-Electron Laser Science (CFEL) have built the world's smallest magnetic data storage unit. It uses just twelve atoms per bit, the basic unit of information, and squeezes a whole byte (8 bit) into as few as 96 atoms.

No less than one third of a car's fuel consumption is spent in overcoming friction, and this friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction by anything from 10% to 80% in various components of a car, according to a joint study by VTT Technical Research Centre of Finland and Argonne National Laboratory (ANL) in USA. It should th

Korea Advanced Institute of Science and Technology (KAIST) announced today that its research team headed by Professor Howon Lee from the IT Convergence Research Institute has developed a technology that will make reading on smartphones and tablet PCs easier than now.
