Welcome to the PPX, the first place to bet on the future of science and technology. It's easy and free: Log on, and we'll give you POP$250,000 in our virtual PopSci Dollars. Use that money to buy propositions you think are likely to happen. If other traders also want to buy, that proposition's price will go up, and you'll make PopSci bucks. Expand your portfolio with bets on energy, space, consumer technology and extreme science, and compete against other players for prizes and bragging rights.
