Thermodynamic magic enables cooling without energy consumption

Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears ...

CEBAF turns on the charm

The world's most advanced particle accelerator for investigating the quark structure of the atom's nucleus has just charmed physicists with a new capability. The production of charm quarks in J/ψ (J/psi) particles by CEBAF ...

Lasers make magnets behave like fluids

For years, researchers have pursued a strange phenomenon: When you hit an ultra-thin magnet with a laser, it suddenly de-magnetizes. Imagine the magnet on your refrigerator falling off.

Spin flipper upends protons

Protons spin. It's an intrinsic property that can affect experiments at accelerators that use beams of protons. Yet flipping proton spins could offer insights into nuclear physics experiments that study the first moments ...

Researchers develop new variant of Maxwell's demon at nanoscale

Maxwell's demon is a machine proposed by James Clerk Maxwell in 1867. The hypothetical machine would use thermal fluctuations to obtain energy, apparently violating the second principle of thermodynamics. Now, researchers ...

Scientists develop way to identify topological materials

In the decades since they were first theorized, scientists have suggested that the exotic properties of topological materials—that is, materials that maintain their electrical properties even in the face of radical temperature ...

Spinning new targets for accelerators

Bob Zwaska, a scientist at the U.S. Department of Energy's Fermilab, was watching a contestant on the cooking show Chopped spin sugar for their dessert when he realized the same principle might be applicable to accelerator ...

Getting a smart tattoo without a needle

A tattoo that is warning you for too many hours of sunlight exposure, or is alerting you for taking your medication? Next to their cosmetic role, tattoos could get new functionality using intelligent ink. That would require ...

Travel through wormholes is possible, but slow

A Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible.
