• Ultra-sharp image uncovers the shocking lives of young stars

  17-06-2016 20:40
  
  An unprecedented view from the Gemini South telescope in Chile probes a swarm of young and forming stars that appear to have been shocked into existence. The group, known as N159W, is located some 158,000 light years away in the Large Magellanic Cloud (LMC), a satellite to our Milky Way Galaxy. Despite the group's distance beyond our galaxy the extreme resolution of the image presents researchers with a fresh perspective on how prior generations of stars can trigger, or shock, the formation of a

• New surface makes oil contamination remove itself

  17-06-2016 20:00
  
  Researchers of Aalto University have developed surfaces where oil transports itself to desired directions. Researchers' oleophobic surfaces are microtextured with radial arrays of undercut stripes. When oil drops fall on surfaces, drops move away from the landing point to the direction set by asymmetric geometrical patterning of the surface. The surfaces open up new avenues for power-free liquid transportation and oil contamination self-removal applications in analytical and fluidic devices.
