Scientists create metal that pumps liquid uphill

(PhysOrg.com) -- In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a ...

The highs and lows of regenerative medicine

Nanoscale manipulation on the surface of materials could stimulate cells to differentiate into specific tissues – eliminating the use of growth or transcription factors.

Tiny wires change behavior at nanoscale

Thin gold wires often used in high-end electronic applications are wonderfully flexible as well as conductive. But those qualities don't necessarily apply to the same wires at the nanoscale.

A spider web's strength lies in more than its silk

While researchers have long known of the incredible strength of spider silk, the robust nature of the tiny filaments cannot alone explain how webs survive multiple tears and winds that exceed hurricane strength.

Friction almost vanishes in microscale graphite

(Phys.org) -- In the phenomenon of superlubricity, two solid surfaces can slide past each other with almost no friction. The effect occurs when the solid surfaces have crystalline structures and their lattices are rotated ...

Researchers ink nanostructures with tiny 'soldering iron'

Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have shed light on the role of temperature in controlling a fabrication technique for drawing chemical patterns as small as 20 nanometers. This technique ...

DNA motor programmed to navigate a network of tracks

Expanding on previous work with engines traveling on straight tracks, a team of researchers at Kyoto University and the University of Oxford have successfully used DNA building blocks to construct a motor capable of navigating ...
