Scientists image nanoparticles in action

(Phys.org) —The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give ...

Scientists detect dark lightning linked to visible lightning

(Phys.org)—Researchers have identified a burst of high-energy radiation known as 'dark lightning" immediately preceding a flash of ordinary lightning. The new finding provides observational evidence that the two phenomena ...

NASA sees three coronal mass ejections in two days

On April 20, 2013, at 2:54 a.m. EDT, the sun erupted with a coronal mass ejection (CME), a solar phenomenon that can send billions of tons of solar particles into space that can affect electronic systems in satellites. Experimental ...

Cooled integrated circuit amplifies with lowest noise so far

Researchers at Chalmers University of Technology, Sweden, have demonstrated an integrated amplifier with the lowest noise performance so far. The amplifier offers new possibilities for detecting the faintest electromagnetic ...

Researchers build fully mechanical phonon laser

(Phys.org) —Researchers working at Japan's NTT Basic Research Laboratories have successfully built an all mechanical phonon laser. In their paper published in Physical Review Letters, the team describes how they built a ...

Saturn to shed its spooky spokes for summer

As Saturn steadily moves along its 29.7-year-long orbit toward summertime in its northern hemisphere NASA's Cassini spacecraft is along for the ride, giving astronomers a front-row seat to seasonal changes taking place on ...

Third radiation belt can wrap around Earth, probes reveal

With the flip of a switch, a pair of instruments designed and built by the University of Colorado Boulder and flying onboard twin NASA space probes have forced the revision of a 50-year-old theory about the structure of the ...

Tiny CREPT instrument to study the radiation belts

A smaller version of an instrument now flying on NASA's Van Allen Probes has won a coveted spot aboard an upcoming NASA-sponsored Cubesat mission—the perfect platform for this pint-size, solid-state telescope.
