Solar-powered plane flies for three and a half days

The solar powered plane flew for 82 hours 37 minutes, exceeding the current official world record for unmanned flight which stands at 30 hours 24 minutes set by Global Hawk in 2001 and Zephyr's previous longest flight of 54 hours achieved last year.

Shaping single photons

ou can squeeze it and stretch it and even chop it up, but a photon is still a photon, a particle of light. Physicists have been manipulating single photons for several years, but now a team has modulated the time profile of a photon. Using the same optical equipment that fashions ordinary light pulses, the team molded single photons into arbitrary shapes, such as a pair of square pulses.

Active gold nanocrystals observed with scanning transmission electron microscopy

Using a pair of scanning transmission electron microscopy (STEM) instruments for which spherical aberration is corrected, researchers for the first time achieved state-of-the-art resolution of the active gold nanocrystals absorbed onto iron oxide surfaces. In fact, the resolution was sensitive enough to even visualize individual gold atoms.
