If you go out after a rain, you may notice spider webs glistening with water droplets. The soggy webs resemble human-made meshes for fog collection: They both have thin fibers that collect water from droplets in the air.

Beyond invisibility—engineering light with metamaterials

Since ancient times, people have experimented with light, cherishing shiny metals like gold and cutting gemstones to brighten their sparkles. Today we are far more advanced in how we work with this ubiquitous energy.

Engineers find a simple yet clever way to boost chip speeds

A typical computer chip includes millions of transistors connected with an extensive network of copper wires. Although chip wires are unimaginably short and thin compared to household wires both have one thing in common: ...

Hybrid nanowires eyed for computers, flexible displays

A new process for coating copper nanowires with graphene - an ultrathin layer of carbon – lowers resistance and heating, suggesting potential applications in computer chips and flexible displays.

New nanomaterial introduced into electrical machines

Lappeenranta University of Technology in Finland has constructed the world's first prototype electrical motor using carbon nanotube yarn in the motor windings. The new technology may significantly enhance the performance.

US eyes phase-out of old telephone network

America's plain old telephone network is rapidly being overtaken by new technology, putting US regulators in a quandary over how to manage the final stages of transformation.
