Geomagnetic Storms Probably Don’t Cause Mass Cetacean Strandings
Solar-induced geomagnetic activity and mass strandings of whales and dolphins on shorelines both show seasonal patterns, but the beachings likely result from multiple environmental factors.

Upstream Propagating Magnetic Dips in the Magnetosheath
The previous consensus that magnetic dips in the magnetosheath can be attributed to non-propagating mirror waves is now shown to be oversimplified.

Power Outage When the Aurora Throws a Curve Ball
Omega-band aurora carries fast propagating electric currents in the azimuthal direction, producing geomagnetically induced currents that can cause power outage on the ground beneath.
