We Were Wrong About Molecular Clouds

From Reactions. For years scientists thought complex molecules could only be formed on Earth. But what if we did find these kinds of molecules out in space? What if they could be formed not just in and around biology but also in cold, dark corners of the universe? Scientists have wondered if they might have…

Does Toyota Know Something That We Don’t?

From Reactions. The 2044 Toyota Prius might just be powered by… ammonia. Ammonia is combustible, and holds promise as a relatively low-effort way to decarbonize the internal combustion engine – but the devil’s in the details. Join George as he discovers at least one detail by burning stuff in his basement. *Note:* the model piston…

Can Science Beat Counterfeit Detector Pens?

From Reactions. Counterfeiting money is wrong. Obviously. But if you wanted to take your totally not real money and fool a counterfeit detection pen, could you do it? We try a number of chemistry tricks to fool the iodine-starch reaction central to these pens, and of course learn a little chemistry along the way. You…
