July 29, 2013 If I say "meet me 28 miles from here," that doesn't seem very far, right? But what if the 28 miles is not on a road or a highway, but straight up? Take a trip with a space shuttle solid rocket booster as it tumbles back to Earth. Headphones on.
July 26, 2013 Car colors are getting cooler, even wintry: All over the world, car buyers are choosing white, silver, gray or black. So who favors warm, springtime colors? Think of a place where you spend half the year bundled up with mittens.

July 24, 2013 Hippos, it turns out, do a wave. Not a get-drunk, get-crazy, paint yourself wave, but a hippo-to-hippo serial roar that moves up and down river banks in Africa.

July 18, 2013 How loud is the loudest sound we can produce? Kiss fans got a taste at an Ottawa concert, but Chris Butler got closer in his sealed, reinforced, amped-up car. Bombs aside, (we'd rather not, thank you ) can we go louder? How much louder?
July 15, 2013 The world's most famous ant scholar likes a good prank. His secret fantasy, he told the novelist Michael Crichton, would be to steal a 25 million year old alarm signal from an ancient ant and use it to panic a modern nest. Oh, what fun! But can he do it?
