Research sheds new light on enigmatic seabird

They are a common sight off the UK's west coast in summer, but we still have much to learn about the Manx shearwater, a remarkably long-lived Atlantic marine bird.

Manipulating transistors at terahertz frequencies

An interdisciplinary team at the Ruhr-Universität Bochum has found a way of accessing the interior of transistors. The researchers have manipulated the electron gas contained within by applying resonators to generate rhythmic ...

Climate is changing fast in West Antarctica

When the ship pulls up at Palmer Station each Antarctic spring, the arriving scientists glance up at the massive glacier that covers most of Anvers Island. It has been retreating about 7 meters per year, and this year is ...

Tandem solar cells are more efficient
