Near ground-state cooling of 2-D trapped ion crystals

Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...

What causes ionic wind?

The phenomenon of ionic wind has been known about for centuries: by applying a voltage to a pair of electrodes, electrons are stripped off nearby air molecules, and the ionized air collides with neutral air molecules as it ...

How mussels make a powerful underwater glue

Blue mussels (Mytilus edulis) spend their days being buffeted by crashing waves. They manage to stay tethered to the rocks or their fellow mussels thanks to a highly effective underwater glue they produce. Because achieving ...

This quantum crystal could be a new dark matter sensor

Physicists at the National Institute of Standards and Technology (NIST) have linked together, or "entangled," the mechanical motion and electronic properties of a tiny blue crystal, giving it a quantum edge in measuring electric ...

Collisions of light produce matter/antimatter from pure energy

Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE's Brookhaven National Laboratory—have ...

The mystery of heavy elements in galactic cosmic rays

Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving ...

Protocells spring into action

A University of Bristol-led team of international scientists with an interest in protoliving technologies, has today published research which paves the way to building new semi-autonomous devices with potential applications ...
