New website provides comprehensive picture of wave energy trials
Information collected during impact assessment activities at wave energy test centres across Europe is to be released through a new website. The site is designed to present detailed information to a non-technical audience, ...
Researchers capture wasted heat, use it to power devices
(Phys.org) —Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine. Researchers at the UCLA Henry Samueli School ...
Wind mission encounters 'SLAMS' waves
(Phys.org) —As Earth moves around the sun, it travels surrounded by a giant bubble created by its own magnetic fields, called the magnetosphere. As the magnetosphere plows through space, it sets up a standing ...
Researcher conducts supercomputer simulations to learn impacts on Earth's magnetic field
(Phys.org) —Space weather is driven by the sun, which has a continually changing magnetic field. When this field accumulates excess energy, it can erupt and send energetic particles into space, sometimes ...
Oregon wave energy project may be delayed
The company planning a wave energy project off the south Oregon coast says it may not be finished this year.
Swift, Chandra explore a youthful 'star wreck'
(Phys.org) —While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite has uncovered the previously unknown remains of a shattered star. Designated G306.3.9 after ...
Hot days cooled by growth in grasslands
Our changing use of the land may have been taking the edge off hot days, scientists say.
Auroras shine light on solar flares
(Phys.org) —Astrophysicists at the University of Glasgow are looking to the Northern and Southern Lights to expand our understanding of solar flares.
Ex nihilo: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons
Deciphering the mysterious math of the solar wind
(Phys.org)—Many areas of scientific research—Earth's weather, ocean currents, the outpouring of magnetic energy from the sun—require mapping out the large scale features of a complex system and its ...
Cassini sheds light on cosmic particle accelerators
(Phys.org)—During a chance encounter with what appears to be an unusually strong blast of solar wind at Saturn, NASA's Cassini spacecraft detected particles being accelerated to ultra-high energies. This ...
Using single quantum dots to probe nanowires
Modern telecommunications happens because of fast electrons and fast photons. Can it get better? Can Moore's law—the doubling of computing power ever 18 months or so—be sustained? Can the compactness ...
New research brings light to star mystery
(Phys.org)—Scientists at Northumbria University have begun to unlock the mystery of why the outer edge of the Sun is much hotter than its surface for the first time.
Forecasting's x-factor: Why the weatherman is often wrong
Have you ever woken up to a sunny forecast only to get soaked on your way to the office? On days like that it's easy to blame the weatherman.
