Atomic clock comparison via data highways
(Phys.org) -- Optical atomic clocks measure time with unprecedented accuracy. However, it is the ability to compare clocks with one another that makes them applicable for high-precision tests in fundamental ...
Quantum physics mimics spooky action into the past
Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) ...
Handheld plasma flashlight rids skin of notorious pathogens
(PhysOrg.com) -- A group of Chinese and Australian scientists have developed a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant.
Saving data in vortex structures: New physical phenomenon could drastically reduce computer energy consumption
A new phenomenon might make computing devices faster, smaller and much more energy-efficient. Moving so-called skyrmions needs 100,000 times smaller currents than existing technologies and the number of atoms ...
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.
Research promises smaller, cheaper therapy machines that could revolutionise cancer treatment
(PhysOrg.com) -- Landmark technology that could revolutionise cancer therapy and pave the way for cleaner, safer nuclear reactors in the future, has been published in Nature Physics today. The pioneering EMMA ( ...
Skeletons point to Columbus voyage for syphilis origins
Skeletons don't lie. But sometimes they may mislead, as in the case of bones that reputedly showed evidence of syphilis in Europe and other parts of the Old World before Christopher Columbus made his historic voyage in 1492.
Physicists 'turn signals' for neuron growth
(PhysOrg.com) -- A new paper scheduled for publication in the January issue of Nature Photonics describes the use of spinning microparticles to direct the growth of nerve fiber, a discovery that could allow ...
Slow road to stability for emulsions
By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.
Study: Ozone from rock fracture could serve as earthquake early warning
Researchers the world over are seeking reliable ways to predict earthquakes, focusing on identifying seismic precursors that, if detected early enough, could serve as early warnings.
Libel case against the scientific journal Nature begins
Cold electrons to aid better design of drugs and materials
A new source of very cold electrons will improve the quality and speed of nanoimaging for drug and materials development to a trillionth of a second.
Prototype 'optics table on a chip' places microwave photon in two colors at once
(PhysOrg.com) -- Researchers at the National Institute of Standards and Technology (NIST) have created a tunable superconducting circuit on a chip that can place a single microwave photon (particle of light) ...
New insights into DNA under the influence of strong forces
(PhysOrg.com) -- Researchers in biophysics, including members from the Niels Bohr Institute, have discovered new properties of DNA and observed a number of phenomena of great importance for cellular mechanisms. ...
