New imaging technique could detect acoustically 'invisible' cracks
The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems.
Pressure transforms a semiconductor into a new state of matter
(Phys.org) —By applying pressure to a semiconductor, researchers have been able to transform a semiconductor into a "topological insulator" (TI), an intriguing state of matter in which a material's interior ...
Physicists publish observation of the 'Charming Socialites'
Protons and neutrons, the particles in an atomic nucleus, are made of smaller pieces called "quarks." Some types of quarks can form particles that exhibit surprising behaviors. Mark Mattson, Ph.D., assistant ...
Data from 'old' experiment appears to constrain the idea of dark photons as part of dark matter theory
New data from PAMELA provides better measure of positrons
Discovery is key to metal wear in sliding parts (w/ Video)
Researchers have discovered a previously unknown mechanism for wear in metals: a swirling, fluid-like microscopic behavior in a solid piece of metal sliding over another.
Snapshots of atoms make it into physics textbooks
Physicist Aneta Stodólna captured the electron positions of hydrogen atoms on camera for the very first time. The snapshots from her quantum-style microscope gained worldwide attention and even made it into ...
Strange physics turns off laser
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter.
There's a kind of Hush surrounding quantum systems
(Phys.org) —Has a persistent noise ever kept you awake at night? Well it isn't just you. Scientists at The University of Nottingham have had the same problem with quantum technologies.
Two independent teams build heat cloaking device
Researchers design first battery-powered invisibility cloak
Researchers at The University of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.
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.
Boron gets a nano refresh: Scientists find stable 2D structures with unique properties
(Phys.org) —The National Nanotechnology Initiative defines nanotechnology as the understanding and control of matter at the nanoscale, at dimensions of approximately 1 and 100 nanometers, where unique phenomena ...
