Scientists blend coinage metals to obtain alloys better than gold

Scientists have developed a novel method for altering the light reflected or absorbed by a material by match-making combinations of gold, silver, and copper into various mixtures of metals, or alloys.

Meet the nanomachines that could drive a medical revolution

Here are four more tiny machines that could have a big impact.

Casimir forces: 21 is not always 3 (w/video)

In the microworld unity is not always strength.

Cellphone principles help microfluidic chip digitize information on living cells (w/video)

Phone calls and text messages reach you wherever you are because your phone has a unique identifying number that sets you apart from everybody else on the network. Researchers are using a similar principle to track cells being sorted on microfluidic chips.

System creates on-demand 'nanotube forests'

A system that uses a laser and electrical current to precisely position and align carbon nanotubes represents a potential new tool for creating electronic devices out of the tiny fibers.

Smart printed sensors monitor movement sequences

A novel transparent sensor material enables movement measuring sensors to be printed onto textiles.

Chemists create battery technology with off-the-charts charging capacity

Researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement.
