New Scientist: For the first time since observations began, ozone destruction over the Arctic in early 2011 was comparable to that over Antarctica. Although the Arctic ozone layer suffers a little damage every winter, the effect is usually short-lived. In the first three months of this year, however, more than 80% of the existing ozone was destroyed at a height of 18–20 km—a loss twice that seen in the two previous record-setting Arctic winters, 1996 and 2005, according to Nathaniel Livesey of the Jet Propulsion Laboratory in Pasadena, California, who is an author of a paper published in Nature. Scientists are now looking to see whether climate change could be partly responsible.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
