A completely new atomic crystal dynamic of the white pigment titanium dioxide discovered

Researchers have confirmed theoretically-predicted interactions between single oxygen molecules and crystalline titanium dioxide.  The results could be of importance for a variety of applications.

Spinning out the future of our electronic devices

To satisfy the world's desire for ever more processing power, at ever diminishing energy cost, in even tinier devices, scientists are looking to spintronics (spin transport electronics) to provide the next generation of high-speed, high-efficiency electronic devices.

Ultracold Big Bang experiment successfully simulates evolution of early universe

(Phys.org) —Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago.

Why electrons pass through very tiny wires less smoothly than expected: Light shed on 20-year-old mystery

Scientists have found an explanation for a mystery that has been puzzling the physics community since 1995. They explain why electrons pass through very tiny wires (known as quantum point contacts) less smoothly than expected. The observations will affect electronics on a nanoscale: ‘Our thinking about this has been too naïve so far.’

New component in the quantum electronics toolbox: Interface between atoms and superconductors

The coherence of quantum systems is the foundation upon which hardware for future information technologies is based. Quantum information is carried by units called quantum bits, or qubits. They can be used to secure electronic communications -- and they enable very fast searches of databases. But qubits are also very unstable. Scientists have now developed a new electronic component which will help to deal with this problem.

The 'woman who understood Newton'

In this month's edition of Physics World, Paula Findlen from Stanford University profiles Laura Bassi—an emblematic and influential physicist from the 18th century who can be regarded as the first ever woman to forge a professional scientific career.

NASA Selects 2013 NASA Innovative Advanced Technology Concepts for Continued Study

NASA has selected six technology proposals for continued study under the agency's Innovative Advanced Concepts (NIAC) Program.

NASA Data Reveals Mega-Canyon under Greenland Ice Sheet

Data from a NASA airborne science mission reveals evidence of a large and previously unknown canyon hidden under a mile of Greenland ice.
