Linear accelerator mimics incredibly energetic particles hitting atmosphere
(Phys.org) —In a SLAC test facility, scientists have set the stage for an experiment that mimics what happens when incredibly energetic particles hit our atmosphere. The players include the lab's historic ...
Nanomotors are controlled, for the first time, inside living cells (w/ video)
For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. ...
Detection of supershear rupture in 2013 Craig, Alaska, earthquake
Seismic ruptures are akin to unzipping a zipper—a gap in the crust starts in one location and travels along the fault in a particular direction. When a strained fault ruptures in an earthquake, seismic waves also spread ...
Researchers solve nano mystery
A technique which may one day be used for tumor therapy and imaging could be greatly improved thanks to new insights obtained by scientists from the University of Twente, the Erasmus MC and the TU Delft.
Early universe 'warmed up' later than previously believed, study finds
A new study from Tel Aviv University reveals that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought. They also imprinted a clear signature ...
Waves costly for fish
(Phys.org) —Big waves are energetically costly for fish, and there are more big waves than ever. The good news is that fish might be able to adapt.
BoomRoom's sound by design uses array of loudspeakers
Climate change's heat—not cold—is the real killer
(Phys.org) —Chill with impunity through this winter's extreme cold – and brace for the next summer heat wave, when fiery temperatures and air pollution conspire to fill hospitals and morgues.
Engineers build first nonreciprocal acoustic circulator: A one-way sound device
A team of researchers at The University of Texas at Austin's Cockrell School of Engineering has built the first-ever circulator for sound. The team's experiments successfully prove that the fundamental symmetry ...
Wave power technology crests economical limits
Commercial amounts of energy can be extracted from relatively small ocean waves, according to a Perth company which has developed technology that it believes is the world's most economical in harnessing wave ...
Researchers take magnetic waves for a spin
Researchers at New York University have developed a method for creating and directing fast moving waves in magnetic fields that have the potential to enhance communication and information processing in computer chips and ...
Array of perfect nanometer-scale spheres that can control the flow of visible light may find use in invisibility cloaks
The optical properties of a material are predominantly determined by its constituent atoms and electrons and the way that these respond to electromagnetic waves. In natural materials, the diversity of possible ...
Seafloor carpet catches waves to generate energy
(Phys.org) —What do champion surfers who gathered at last week's Mavericks Invitational have in common with a UC Berkeley engineer? They all are looking to harness the power of big ocean waves.
Is there an ocean beneath our feet?
(Phys.org) —Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth's oceans to the upper mantle than previously thought.
