In Greenland, a climate change mystery with clues written in water and stone

•January 20, 2016 • 1 Comment

About a decade ago, several of Greenland’s biggest glaciers suddenly began melting. A decade later, two groups of scientists are trying to unlock the secrets behind a scientific mystery story with potentially big consequences for the future of the island’s rapidly-melting ice sheet.

Minorities are historically underrepresented in science, technology, engineering and math fields. John Dimandja is a Congolese chemist on the faculty of Spelman College who’s pointing the way into STEM careers for students of color.

Turning ice into fire. Iceland goes for drama.

Iceland is — geologically speaking — a crazy place. The local language, for instance, includes a specific word to describe the phenomenon for a volcano detonating beneath a glacier and triggering a flash flood. And now our changing planet may be setting a new geological domino effect in motion.

A New Way to See the Brain

Scientists at MIT have embedded slices of brain in the absorbent material found in diapers, which swells 4-5 times its normal size. And when they look at the expanded result using an ordinary light microscope, they see an unprecedented view of nerve fibers, cells, and proteins. It’s the deepest look into the brain we’ve ever had.

Is an artificial tree part of the solution to climate change? These guys think so.

Trees are nature’s tool for pulling carbon dioxide out of the air, but there aren’t enough trees in the world to suck up all the CO2 humans are putting there. That’s why researchers are pushing to create artificial leaves to help fight climate change. I visit with two teams of researchers pursuing different approaches to the formidable challenge.

Glacial Time Travel

I’m currently traveling to the future, with the help of a couple magnificent glaciers. (Translation: I’m on a 3-week reporting trip in Greenland and Iceland!)

In due time, my radio stories will air on PRI’s The World and my web videos will be published by NOVA.  My trip is supported by the Pulitzer Center on Crisis Reporting.
