Squeezing light into metals

Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Earth-sized planets may be plentiful

There could be many more small planets than previously thought, thanks to the discovery that they don't need to form around stars rich in heavy elements.

'Pristine' gas from early universe discovered

Astronomers have discovered two clouds of gas that are still in the same state as they were just minutes after the Big Bang.

Astronomers discover 'impossible' star

A team of European astronomers have discovered a star that by rights shouldn't exist - it's simply not dense enough for current models to explain its formation.
