This week’s theme: Getting Graphic.

1. You have to look under the hood.

Last week in Science on The Fly, we discussed monumental water loss from Antarctic glaciers. This week, a great tweet from Science Magazine shows us exactly how a Mt. Everest’s-worth of water is slipping away every two years: from the bottom of the ice shelf.

“Warming of the water that flows under Antarctic ice shelves is key to their melting”

2. Periodic Table-top emoji.

We’re not exactly sure why a company that makes light bulbs, MRI scanners and robots is messing with emojis. I sense a deeper plan afoot: something involving world domination by MRI-scanning robots.

Then again, it would be hard for just about anyone to pass up an opportunity to explode things while getting on social media with Bill Nye. This is exactly what General Electric (@generalelectric) is accomplishing with Emoji Science. They are being fun, cute, and in their own way, a bit innovative. If you have kids, or enjoy acting like a kid—like to see flasks running over for any reason—follow the link to get your #EmojiScience on.

“On 12.10, get ready to meet the emoji table of experiments. #EmojiScience”

The world's first #EmojiScience lab is open! Send an emoji to 'generalelectric' on Snapchat for some science. https://t.co/GoTWqVH9i2

3. The Space Marble

Ever wonder where the classic blue marble picture came from? Ok, we all can deduce that it came from space. But who took this classic shot? What were they doing up there? Who were they and where were they going?

We can thank the brave astronauts of the 1972 Apollo 17 mission for our classic view of the pale blue dot. Their trajectory on the way to the Moon allowed them to take the first South Pole photo of the Apollo era.

Apollo 17’s mission was a bunch of cool moon seismology and geology—“a heat flow experiment; lunar seismic profiling, lunar surface gravimeter, lunar atmospheric composition experiment”—as well as rock samples and biomedical experiments.
