'Stealth' material hides hot objects from infrared eyes

Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.

Superconducting vortices quantize ordinary metal

Researchers have discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor.

The photoelectric effect in stereo

In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce the exact location of a photoionization event.

Insulator-metal transition at the nanoscale: x-ray holography reveals existence of nano-patchwork

In a recent study, researchers have finally been able to probe the phase transitions that occur in thin films of vanadium dioxide using resonant soft X-ray holography.

Is nature exclusively left-handed? Using chilled atoms to find out

Elegant techniques of trapping and polarizing atoms open vistas for beta-decay tests of fundamental symmetries, key to understanding the most basic forces and particles constituting our universe.

As future batteries, hybrid supercapacitors are super-charged

A new supercapacitor could be a competitive alternative to lithium-ion batteries.

Sense like a shark: Saltwater-submersible films

A nickelate thin film senses electric field changes analogous to the electroreception sensing organ in sharks, which detects the bioelectric fields of prey.
