New metamaterial manipulates sound to improve acoustic imaging

Researchers have developed a metamaterial made of paper and aluminum that can manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the angles at which sound passes through the metamaterial.

Researchers tailor power source for wearable electronics

Researchers have developed flexible wire-shaped microsupercapacitors that can be woven into a jacket, shirt or dress.

Big moves in protein structure prediction and design

Custom design with atomic level accuracy enables researchers to craft a whole new world of proteins.

Solar cells that can face almost any direction and keep themselves clean

Researchers developed a glass coating that incorporates ultrathin nanorods and honeycomb nanowalls that can help underlying solar cells harvest sunlight from multiple angles.

The tiniest color picture ever printed

The printed image measures a minuscule 0.0092 square mm in area, or 80 x 115 microns. That's about the cross-sectional area of a human hair or the area covered by a single pixel of a retina display.

Physics for the mechanism of slow change in microscopic magnetic structures revealed

Researchers have studied in detail, a slow change of microscopic magnetic structures in metallic wires induced by external driving forces, commonly called 'creep' motion. This has allowed them to clarify the physics of how the driving forces, magnetic fields or electric currents, act on the magnetic structure.

Time-resolved measurement of the anomalous velocity

Movement of charge carriers perpendicular to an electric driving field in a solid state system detected for the first time with sub-picosecond time resolution.

A molecular light switch?... Just add water

A bit of stray moisture during an experiment tipped off scientists about the strange behavior of a complex oxide material they were studying - shedding light on its potential for improving chemical sensors, computing and information storage.

To stop cancer's spread, take out its nanoscale communication channels

A study offers a new view of how cancer cells extend their reach, co-opting and transforming normal cells through 'metastatic hijacking'.

Nanotechnology breakthrough revolutionizes laser printing

Thanks to a new revolutionary laser printing technology, it is now possible to print this press release in colour on an area no bigger than a hair.

Clues on the development of magnetic sensors with pure spin current

Researchers have succeeded in detecting magnetic fluctuations with pure spin current in a much more sensitive way than conventional magnetization measurements.

Computer calculations indicate the best places to look for nanowire catalysts

Scientists cientists have created a 'prospector?s guide' to help researchers locate the best germanium?silicon nanowires for catalyzing important clean-energy reactions.
