For decades, scientists have been studying the cause of the Younger Dryas, and trying to figure out if something like it could happen again. And it turns out that what caused this event is the subject of a heated debate.

Raindrops and snowflakes generally start to form around something else in the air, like a speck of dust, but sometimes that something else is bacteria.

We have the first published example of using light and gene therapy to restore someone's vision! And in heavier (metal) news, a recent study found surprisingly high levels of mercury in meltwater from the Greenland Ice Sheet.

The IPCC has released a special report assessing how the world’s ice and oceans are faring under our changing climate, and scientists may be one step closer to a cure for the common cold!
