Scientists make breakthrough solar technology
In the near future, solar panels will not only be more efficient but also a lot cheaper and affordable for everyone, thanks to research by Nanyang Technological University (NTU) scientists.
Astronomers discover planet that shouldn't be there
An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. It is the first exoplanet ...
Researchers create a low-cost, long-lasting water splitter made of silicon and nickel
Stanford University scientists have created a silicon-based water splitter that is both low-cost and corrosion-free. The novel device – a silicon semiconductor coated in an ultrathin layer of nickel – ...
First ever evidence of a comet striking Earth
The first ever evidence of a comet entering Earth's atmosphere and exploding, raining down a shock wave of fire which obliterated every life form in its path, has been discovered by a team of South African ...
Tiny 'Lego brick'-style studs make solar panels a quarter more efficient
(Phys.org) —Rows of aluminum studs help solar panels extract more energy from sunlight than those with flat surfaces.
Wireless device converts 'lost' energy into electric power
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar ...

Rosetta: 100 days to wake-up (w/ Video)
(Phys.org) —ESA's comet-chasing mission Rosetta will wake up in 100 days' time from deep-space hibernation to reach the destination it has been cruising towards for a decade.
Researchers shed new light on dark energy, cosmic speed-up
In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion.
How NASA revived the Kepler Space Telescope
(Phys.org) —You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again.
3D printers' could change our economy and our lives
(Phys.org) —"When you produce something yourself instead of purchasing it, that changes your relationship to it," says Chelsea Schelly, assistant professor of social sciences. She's discussing the current ...
