POPSHow Anti-Matter Propulsion Works It's not rocket science...at least rockets as we know them. :) So, why haven't we built a matter-antimatter reaction engine? The problem with developing antimatter propulsion is that there is a lack of antimatter existing in the universe. For now, we will have to create our own antimatter. Luckily, there is technology available to create antimatter through the use of high-energy particle colliders, also called "atom smashers." But these high-energy particle accelerators only produce one or two picograms of antiprotons each year. A picogram is a trillionth of a gram. It states that anti-matter propulsion is the most energy efficient propulsion. I suspect that will be true as long as the process of making the anti-matter is itself efficient enough to make it feasible.

POPSScientific Literacy And that's what science really stands to give them. That's the reason you and I are drawn to science. And I can see no reason to offer them anything less.

POPSMedicine Rock After a year of effort, though, they finally arrived in Louisiana. The men turned down several offers for the meteorite and shipped it to New York, where a chemist found that it was made not of platinum, but of iron. The explorers didn't profit from the meteorite, which was named the Texas Iron. But their foray prompted Spain to step up its patrols. And the meteorite was one of the first to receive extensive scientific review. Today, it's on display at the Peabody Museum at Yale University.

POPSNew Cure for Bruises? Could very well turn out to be insightful. I just wouldn't want to be the test subject for further clinical studies.
