Majorana particles, penguins from space and jokes about auroras

In environmental news, satellite imaging was used to count emperor penguins (Scientific American). Since Antarctica is so very inhospitable to people, this method of an idea of the numbers of penguins gives us a better idea of when they are threatened.

Auroras spotted on Uranus (National Geographic) is a topic that just begs for off-color jokes, but it's also a neat look at our own solar system, which unfortunately we still don't know enough about.

In particle physics, an Italian scientist 75 years ago predicted a particle that could be it's own anti-particle. The name of the scientist, and the hypothetical fermion named after him is Majorana. Instead of using massive equipment like at Cern, scientists have been coming up with small devices to try and track this elusive particle. One such device shows evidence (BBC).
