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.

Researchers develop versatile method for developing new materials

Researchers at the University of Twente research institute MESA+ have devised an elegant method for fitting various functional coatings to silicon microwires. The method makes it possible to create relatively easily a wire ...

Wearable capacitor technology to power mobile electronics

Industrial design researchers at Brunel University London have solved two of the major challenges which prevent everyday items of clothing being turned into power sources for smartphones, tablets and other personal tech.

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: ...
