Physicists show how lifeless particles can become 'life-like' by switching behaviors

Physicists at Emory University have shown how a system of lifeless particles can become "life-like" by collectively switching back and forth between crystalline and fluid states—even when the environment remains stable.

A bit of a 'quantum magic trick': Experiment shows how to speed up frequency measurement

Is there a faster way to determine a frequency? It turns out there is.

Physics explains protein unpredictability

University of Oregon scientists theorized that they could manipulate a protein one mutation at a time and predict its evolution. They sought to prove it. And failed.

Hard to solve a Rubik's cube? Try the adaptive toolbox theory on rationality

Contrary to what cognitive scientists long thought, the adaptive toolbox theory - a theory about human rationality - contains an NP-hard problem which asks for demonic computational powers just like the travelling salesman problem and the Rubik's Cube. Maria Otworowska, Iris van Rooij, and colleagues from Radboud University publish these findings in Cognitive Science.

Ions in the spotlight

New scientific results have been given a special place in the Nature Photonics journal. They focus on the effective isolation of ions in optical and electrostatic traps.

Unlocking the potential of magnetic skyrmions

Magnetic skyrmions offer the promise of next-generation memory and computing technologies, such as cache memory devices and cloud computing. Now A*STAR researchers have developed an innovative technique for making tunable skyrmions that could help unlock their potential.

Wave properties of particles can manifest in collisions

Dmitry Karlovets, senior researcher at the TSU Faculty of Physics, and Valery Serbo from the Institute of Mathematics of the SB RAS have shown that it is possible to observe the wave properties of massive particles at room temperature in practically any modern physics laboratory—it is only necessary to precisely focus the beam of particles. The results of the theoretical research were published in Physical Review Letters.

Researchers demonstrate how to control liquid crystal patterns

Researchers have demonstrated that not only could patterns on liquid crystals be controlled at nanoscales, but the changes could be visible without microscopes. The work could potentially pave the way to new biosensors and energy-efficient harvesting devices.

Briefings, NASA Television Coverage Set for Launch of NOAA Weather Satellite

Officials from the National Oceanic and Atmospheric Administration (NOAA) and NASA are preparing for the upcoming launch of the Joint Polar Satellite System-1 (JPSS-1), the first in a series of four highly advanced NOAA polar-orbiting satellites designed to improve the accuracy of weather forecasts out to seven days.

Physicists describe new dark matter detection strategy

Physicists from Brown University have devised a new strategy for directly detecting dark matter, the elusive material thought to account for the majority of matter in the universe.
