What Is A Flame?
When Alan Alda was 11 years old, he asked his teacher what a flame was. He didn’t like the answer he got. So now, in partnership with the Center for Communicating Science, he decided to ask the world’s scientists and science communicators to answer this question in terms that the world’s 11-year-olds can understand. That’s The Flame Challenge.
The entry above is my favorite (although I am biased, because it’s by a team of people that I admire). This is by The Fabulab, a project of Jeanne Garbarino, Deborah Berebichez, and Perrin Ireland (with the help of a few others).
I would have done one too, but it seems like all my grad school friends are too “busy” or something to work on awesome video projects, pssh. Anyway, these ladies have my vote! What do you think?
Alan Alda rules. The center for communicating science rules. Alda came to our school and did this whole science improvisation class with a bunch of grad students..that ruled, too.

Astronauts needed for mock Mars mission in Hawaii
If you’ve ever dreamed of becoming an astronaut and have four months to spare, you might have the “right stuff” to fly to Mars … well, sort of. The fake Mars mission will test how volunteers feel about the types of food on the menu for astronauts during long-duration space trips.

Slower than Light Neutrinos
Earlier this year, an international team of scientists announced they had found neutrinos — tiny particles with an equally tiny but non-zero mass — traveling faster than the speed of light. Unable to find a flaw themselves, the team put out a call for physicists worldwide to check their experiment. One physicist who answered the call was Dr. Ramanath Cowsik. He found a potentially fatal flaw in the experiment that challenged the existence of faster than light neutrinos.

A Toast to the Chemistry of Champagne
You gonna be poppin’ da Cris tomorrow night? You might want to uncork this chemistry lesson, then. From fermentation to the perfect pour, all the science behind the bubbles.
Cue “Tiiiiiiiiny bubbles …”
