Nature: At a meeting last week in Bremen, Germany, scientists reported the first results from the Solar Dynamics Observatory. Launched in February into a geosynchronous orbit, SDO observes the Sun’s magnetic field structure and atmosphere on short length and time scales, the aim being to relate magnetic variability to the internal and external dynamics of solar plasma. Nature‘s Richard Lovett summarizes the findings so far.
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.
