Ultrafast heating of water: This pot boils faster than you can watch it
Scientists from the Hamburg Center for Free-Electron Laser Science have devised a novel way to boil water in less than a trillionth of a second. The theoretical concept, which has not yet been demonstrated ...
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.
Signal control with light frequencies
In a review article in Nature Photonics Ferenc Krausz and Mark Stockman discuss the prospects, recent experimental and theoretical findings open for the future of signal processing.
Frogs without ears hear with their mouth
Gardiner's frogs from the Seychelles islands, one of the smallest frogs in the world, do not possess a middle ear with an eardrum yet can croak themselves, and hear other frogs. An international team of scientists ...
Report: Tsunami would swamp California's economy (Update)
If a monster earthquake struck off Alaska's coast, tsunami waves would rush toward California, crippling the nation's busiest port complex and flooding coastal communities, a report released Wednesday suggests.
Thermal conductance can be controlled like waves using nanostructures
Thermal conduction is a familiar everyday phenomenon. In a hot sauna, for instance, you can sit comfortably on a wooden bench that has a temperature of 100C (212F), but if you touch a metallic nail with the same temperature, ...
The cool glow of star formation: First light of powerful new camera on APEX
A new instrument called ArTeMiS has been successfully installed on APEX—the Atacama Pathfinder Experiment. APEX is a 12-metre diameter telescope located high in the Atacama Desert, which operates at millimetre ...
Nanoscale friction: High energy losses in the vicinity of charge density waves
In collaboration with the University of Basel, an international team of researchers has observed a strong energy loss caused by frictional effects in the vicinity of charge density waves. This may have practical ...
'Virtual earthquakes' used to forecast Los Angeles quake risk
Stanford scientists are using weak vibrations generated by the Earth's oceans to produce "virtual earthquakes" that can be used to predict the ground movement and shaking hazard to buildings from real quakes.
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.
The nature of color: New formula to calculate hue improves accuracy of color analysis
A stroll through the produce aisle in your local grocery store exhibits a plethora of vivid colors. From opposing hues, like red apples next to green celery, to subtler variations, such as light to dark purple grapes, every ...
