Scientists have produced the best simulation yet of the gravity waves produced by colliding black holes. You don’t have to know anything about the science involved to enjoy the fruits of their labours in this video clip, which represents something that would take just an hour or so in real time but took 2,000 processors …
Some risk factors you can’t do anything about
Take this study: “Taller people more likely to develop atrial fibrillation” it says. I’m 6’2″, not extraordinarily tall, but tall enough. Over a period of 10 years beginning in 1986 I suffered four brief (no more than a couple of days at worst) spells of atrial fibrillation. It’s now been just about 10 years since …
Now that’s what I call a compact!
Rice University scientists have attached light-powered motors to the single-molecule cars they announced a few months ago. How small are these cars? Well… The nanocars, which measure just 3-by-4 nanometers, are about the same width as a strand of DNA, but much shorter than DNA. About 20,000 of these nanocars could be parked, side-by-side, across …
