Research explores natural selection in action

Phys.Org - 30 Aug 2017
But early in the new year, an anomaly occurred in the polar vortex, a system of low pressure that traps the Arctic's bitter cold over the pole. A weakening in the vortex allowed that chill to spill out. Campbell-Staton, who grew up in South Carolina ...

The Ceiling for Unpowered Flight Just Went Up 2000 Feet

Atlas Obscura - 08 Sep 2017
In this case, the team has to wait for something called the stratospheric polar night jet, which are strong winter winds that trap cold polar air and form polar vortices. For this flight, the Perlan 2 team flew out of the airport in El Calafate ...
