North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar energy devices and reduce the cost of solar energy production.

Nerve circuits let the brain turn down sounds that come from our own actions, and turn up other sounds we need to pay attention to, say researchers.

Unlike volcanoes that emerge from collision zones between tectonic plates, hotspot volcanoes form in the middle of the plates.

“If one of these objects was found orbiting a star, there is a good chance that it would be called a planet.”

A tiny club at the end of a long fishing line-type appendage resembles the movements of small marine organisms. The squid attracts its prey, then attacks.

Astronomers have used ESO's New Technology Telescope and the NASA/ESA Hubble Space Telescope to explore more than 100 planetary nebulae in the central bulge of our galaxy. They have found that butterfly-shaped members of this cosmic family tend to be mysteriously aligned — a surprising result given their different histories and varied properties.

Cassini spacecraft images show the development of the largest storm seen on the planet since 1990. On Saturn, not only are storms much bigger than on Earth, they're far more violent, with vertical winds of more than 300 miles per hour.

"For decades people have known that the solar cycle depends on the poleward flow or material, changing the magnetic fields from one cycle to the next. We mapped out what we believed to be the flow pattern in the 1990s, but the results didn't quite make sense." - Philip Scherrer

A new Dartmouth study links an abrupt global change to a colder, dryer climate 12,900 years ago to the impact of an asteroid or comet in Quebec

Gardiner’s frogs from the Seychelles islands, one of the smallest frogs in the world, do not possess a middle ear with an eardrum yet can croak themselves, and hear other frogs.
