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.
Newport, Ore., to host wave energy test site
Newport, Ore., has been selected as the site for what its backers call a utility-scale wave energy test site.
First direct evidence that breaking waves cause horizontal eddies
As ocean waves pass from deeper water into the shallow coastal regions, they begin to break, churning up the surf zone waters. At the edges of the crests of the breaking waves, horizontally-rotating eddies (vertical vortices) ...
Magnetic shell provides unprecedented control of magnetic fields
Missile and meteorite impacts are more complex at the granular level than scientists previously thought
(Phys.org)—High-speed video of projectiles slamming into a bed of disks has given scientists a new microscopic picture of the way a meteorite or missile transfers the energy of its impact to sand and dirt ...
Cosmic radio waves mimic chirping of 'alien birds' (Update)
Twin spacecraft have captured the clearest sounds yet from Earth's radiation belts—and they mimic the chirping of birds.
US roads, airports unready for extreme weather
(AP)—America's lifelines—its roads, airports, railways and transit systems—are getting hammered by extreme weather beyond what their builders imagined, leaving states and cities searching for ways to ...
Climate change may increase Europe's north-south divide
Rising temperatures could widen the gap between the Europe's rich and poor nations, an EU agency warned Wednesday, as it announced the warmest decade on record in the continent.
New energy technologies promise brighter future
In three studies published in the current issue of Technology and Innovation – Proceedings of the National Academy of Inventors, innovators unveil creative technologies that could change our sources of energy, change our use of energy ...
Invisibility cloaking to shield floating objects from waves
A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on transformation optics, ...
