The annihilating effects of space travel

Long distance space travel could create the ultimate 'killer entrance', devastating your destination and anything around the arriving spacecraft, according to calculations by Professor Geraint Lewis and two honours students from the University of Sydney.

Mn-doped ZnS is unsuitable to act as a dilute magnetic semiconductor

Dilute magnetic semiconductors (DMS) have recently been a major focus of magnetic semiconductor research. A laboratory from the University of Science and Technology of China explored the feasibility of doping manganese (Mn) into zinc sulfide (ZnS) to obtain magnetic semiconductors.

Quantum physicists shed new light on relation between entanglement and nonlocality

(PhysOrg.com) -- New research from the University of Bristol may disprove a long-standing conjecture made by one of the founders of quantum information science: that quantum states featuring ‘positive partial transpose’, a particular symmetry under time-reversal, can never lead to nonlocality.

Quantum teleportation analysed by mathematical separation tool

Scientists from the University of Vienna's Faculty of Physics in Austria recently gave a theoretical description of teleportation phenomena in sub-atomic scale physical systems, in a publication in the European Physical Journal D.

Bending light with better precision

Physicists from the University of California at San Diego (UCSD) have demonstrated a new technique to control the speed and direction of light using memory metamaterials whose properties can be repeatedly changed.

Rainbows without pigments offer new defense against fraud

Scientists from the University of Sheffield have developed pigment-free, intensely coloured polymer materials, which could provide new, anti-counterfeit devices on passports or banknotes due to their difficulty to copy.

Fundamental question on how life started solved?

For carbon, the basis of life, to be able to form in the stars, a certain state of the carbon nucleus plays an essential role. In cooperation with US colleagues, physicists from the University of Bonn and Ruhr-Universitat Bochum have been able to calculate this legendary carbon nucleus, solving a problem that has kept science guessing for more than 50 years.
