• Realistic data needed to evolve the 21st century power grid

  25-01-2016 23:55
  
  Say you have a great new theory or technology to improve the nation's energy backbone—the electric grid. Wouldn't it be great to test it against a model complete with details that would tell you how your ideas would work? But it's a challenge, because existing sets of data are too small or outdated; and you don't have access to real data from the grid because of security and privacy issues.

• Ocean warming underestimated, study finds

  25-01-2016 22:07
  
  To date, research on the effects of climate change has underestimated the contribution of seawater expansion to sea level rise due to warming of the oceans. A team of researchers at the University of Bonn has now investigated, using satellite data, that this effect was almost twice as large over the past twelve years than previously assumed. That may result in, for example, significantly increased risks of storm surges. The scientists are presenting their findings in the renowned scientific jour

• Theorists propose a new method to probe the beginning of the universe

  25-01-2016 18:24
  
  How did the universe begin? And what came before the Big Bang? Cosmologists have asked these questions ever since discovering that our universe is expanding. The answers aren't easy to determine. The beginning of the cosmos is cloaked and hidden from the view of our most powerful telescopes. Yet observations we make today can give clues to the universe's origin. New research suggests a novel way of probing the beginning of space and time to determine which of the competing theories is correct.

• Did ear sensory cell stereocilia evolve from gut microvilli?

  25-01-2016 18:00
  
  Evolution likes to borrow. It can take an already-successful biological structure and alter it until it serves a new function. Two independent groups studying the proteins that organize gut microvilli now suspect that this may have been the case in the development of inner ear hair cell stereocilia. While functionally very different, the protein complexes that organize microvilli and stereocilia have striking parallels. Both papers appear January 25 in Developmental Cell.

  NASA’s Cassini Spacecraft delivers another great image of Enceladus. This half-lit view of Enceladus bears a passing resemblance to similar views of Earth’s own natural satellite, but the similarities end there. Earth’s rocky moon is covered in dark, volcanic basins and brighter, mountainous highlands — both exceedingly ancient. The surface of icy Enceladus is uniformly […]
