A massive impact crater the size of the city of Paris has been discovered under the ice sheet in northern Greenland. Partially hidden under the Hiawatha Glacier, this 31-kilometer (19.3-mile) crater is estimated to be no older than three million years, but the researchers believe that it was formed much more recently, possibly as late as 12,000 years ago, making it the largest impact crater of its kind on Earth.

Researchers in Antarctica have discovered that the frozen continent’s ice shelves produce an audible sound when the wind passes over the surface snow, a haunting song from a landscape that remains alien to the majority of us. The researchers also found that the "song" changes as the surface conditions of the ice changes — meaning that this Antarctica aria might become useful in tracking the effects of climate change on the ice at the bottom of the Earth.

Clouds of aggressive nickel-sized mosquitoes called gallinippers have descended on 27 counties in North Carolina, the result of untold numbers of the insect’s eggs being activated by the catastrophic flooding caused by hurricane Florence. Unlike most mosquitoes, Gallinippers can lay their eggs in dry conditions, of which can lay dormant for months or years, and hatch when wet conditions develop. The females can be particularly aggressive, mobbing large mammals such as humans or even cattle in order to feed.
