A 3-D printed plastic disk can help pick out a voice from a crowd, a task that is easy for people but not for technology. The device could lead to improved voice recognition and hearing aids.
Hydrogen sulfide becomes a superconductor at the surprisingly high temperature of 203 K (–70 °C), when under a pressure of 1.5 million bar, according to recent work done by physicists in Germany. This smashes the previous record for conventional superconductivity...
Physicists from the ALICE experiment at CERN’s Large Hadron Collider have compared antideuterons and deuterons (a proton, or hydrogen nucleus, with an additional neutron), as well as antihelium-3 nuclei and helium-3 nuclei (two protons plus a neutron). The new result...
It's a study in contrasts. For more than a decade, physicists have been puzzling over dark energy, the mysterious stuff that’s blowing space apart and has been detected only by studying the universe on the largest scales. Now, researchers have probed its properties...
Physicists have crafted a wormhole that tunnels a magnetic field through space. The device can transmit the magnetic field from one point in space to another point, through a path that is magnetically invisible. Read the associated Physical Review Letters abstract.
A newly discovered dwarf galaxy orbiting our Milky Way appears to be radiating gamma rays, according to an analysis by physicists at Carnegie Mellon, Brown and Cambridge universities. The exact source of this high-energy light is uncertain...
