Reevaluation of 2005 measurement deepens mystery of neutron lifetime discrepancy
New application of physics tools used in biology
A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology.
New data from PAMELA provides better measure of positrons
The origins of handedness in life
Physicists eye neural fly data, find formula for Zipf's law
Physicists have identified a mechanism that may help explain Zipf's law – a unique pattern of behavior found in disparate systems, including complex biological ones. The journal Physical Review Letters is pub ...
Pyramid nanoscale antennas beam light up and down
Researchers from FOM Institute AMOLF and Philips Research have designed and fabricated a new type of nanoscale antenna. The new antennas look like pyramids, rather than the more commonly used straight pillars. ...
Researchers discover midair collisions enhance the strength of sandstorms
Improved interface for a quantum internet
A quantum network requires efficient interfaces over which information can be transferred from matter to light and back. In the current issue of Physical Review Letters, Innsbruck physicists led by Rainer ...
Relaxation helps pack DNA into a virus
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published ...
Data from 'old' experiment appears to constrain the idea of dark photons as part of dark matter theory
The physics of curly hair: Researchers develop first detailed model for a 3-D strand of curly hair
The heroes and villains in animated films tend to be on opposite ends of the moral spectrum. But they're often similar in their hair, which is usually extremely rigid or—if it moves at all—is straight ...
More precision from less predictability: A new quantum trade-off
An important advance in the quantitative understanding and experimental verification of complementarity; arguably the most important foundational principle of quantum mechanics.
Cool electron acceleration
Physicists from the Max-Planck-Institute of Quantum Optics produced electron pulses from a laser accelerator whose individual particles all have nearly the same, tuneable energy.
Quantum sensor's advantages survive entanglement breakdown
The extraordinary promise of quantum information processing—solving problems that classical computers can't, perfectly secure communication—depends on a phenomenon called "entanglement," in which the ...
