Baby Gets Hit By Train, Strolls Away...There's a Hole In My Heart That Can Only Be Filled By—Stem Cells?...Beware Bobbies Bearing BlackBerries...Science Figures Out Why We Break Out Bubbly

Sure it's been the lead story on CNN and a big story on Gawker, but there just wasn't enough DIY mechanics or cellphone-related mayhem for us to pounce on this little gem. As a dad, I don't like seeing shit like this, but knowing there's a happy ending made it a bit easier to view. Oops, did I give too much away? [Gawker]

Hairband balladeers from the roaring '80s will be disappointed to learn that holes in the heart previously only able to be filled by some girl who is already dating some other guy can now be filled by a patch made of stem cells. As for the rest of us, we naturally assumed that if stem cells could give Christopher "Butthole" Reeve real Superman strength and build replica's of Shakey's Pizza, well, of course they can patch heart holes.

By March of next year, many British police officers will be handed a smartphone in order to maintain communication while increasing time in the field. It may work, assuming they block like a million distractions. Frankly, the only reason I wanted to even mention this in Remainders was to remind the world of that stroke of British police genius, Hot Fuzz, through Photoshop. It was that or an image of the gmilfy Prime Suspect herself, Helen Mirren. Did I choose wrong? [BBC via Engadget]

Science produces explanations great and small, and finally got around to one we've been waiting for since Heinrich "Coca" Cola invented the fizzy beverage: Why do we love the carbonation? Everyone used to think it was the exploding carbonation bubbles, but sure enough, it's the carbon dioxide itself—you listening, Al Gore???—that sends a message to open up the sour taste buds, delivering a genuine flavor change. Sure, it's not gadget news, but now, when you head out to the bars, you can order beer in the name of science. [Daily Mail UK]
