Chips that can steer light
If you want to create a moving light source, you have a few possibilities. One is to mount a light emitter in some kind of mechanical housing—the approach used in, say, theatrical spotlights, which stagehands ...
Magma in mantle has deep impact: Study suggests rocks melt at a greater depth than once thought
Magma forms far deeper than geologists previously thought, according to new research at Rice University.
URI oceanography student uses crashing waves on shorelines to study Earth's interior
Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated ...
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.
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, ...
Research comes home to roost: six years later, Revelle returns
After a six-year voyage on the high seas, braving crashing waves and typhoon-force winds around the world in the name of science, research vessel (R/V) Roger Revelle is coming home to San Diego today.
Geologist calls for advances in restoration sedimentology
Rapid advances in the new and developing field of restoration sedimentology will be needed to protect the world's river deltas from an array of threats, Indiana University Bloomington geologist Douglas A. ...
High-speed imagery captures new sea spray formation mechanism
When strong winds blow over ocean waves, small droplets of sea spray rise into the air, enhancing the exchange of heat, mass, and energy between the air and the sea. How effective sea spray is at mediating each of these dynamics ...
How the bomb could help us predict next month's weather
Technology first used to listen for secret H-bomb tests could now help forecasters tell us what the weather's going to be like up to a month in advance.
'Planetary emergency' due to Arctic melt, experts warn
Experts warned of a "planetary emergency" due to the unforeseen global consequences of Arctic ice melt, including methane gas released from permafrost regions currently under ice.
Mathematicians show how shallow water may help explain tsunami power
(Phys.org)—While wave watching is a favorite pastime of beachgoers, few notice what is happening in the shallowest water. A closer look by two University of Colorado Boulder applied mathematicians has led ...
Weighing the Ocean: Solving the biggest problem in sea level science
(Phys.org)—Oceanographers from Newcastle and Liverpool have thought of a novel way to measure the ocean – weigh it.
Homing in on a potential pre-quake signal
In a new analysis of the 2004 magnitude 6.0 Parkfield earthquake in California, David Schaff suggests some limits on how changes measured by ambient seismic noise could be used as a pre-earthquake signal.
