"When the magnetic field lines curve symmetrically around Earth, aurorae should appear in identical places in the Northern and Southern hemispheres. And, if you could view both light displays simultaneously, they would look pretty much the same. But such a scenario is actually “quite rare,” says Aaron Ridley, a magnetosphere researcher at the University of Michigan who was not involved in the new study."

Wolves and Wolverines: A Complicated Relationship
"Wolves are a common predator of wolverines, but the relationship is more complicated than simply predator-prey. Across their range, wolverines can be seen tentatively approaching days-old wolf kills, crunching bones and tearing at leftover flesh. They are what is considered a “facultative scavenger”—they eat carrion when it’s available but are quite capable of hunting their own prey when it’s not.
Although it’s difficult to examine interspecific relationships of wide-ranging species such as these in the wild, scientists have learned a lot in the last decade thanks to some innovative studies."
