scottbomb sends in this feel-good story of an engineer-hero, calling it "one of the coolest stories I've read in a long time." "A manager of Boeing's F22 fighter-jet program, Innes dodged the truck, then looked back to see that the driver was slumped over the wheel. He knew a busy intersection was just ahead, and he had to act fast. Without consulting the passengers in his minivan — 'there was no time to take a vote' — Innes kicked into engineer mode. 'Basic physics: If I could get in front of him and let him hit me, the delta difference in speed would just be a few miles an hour, and we could slow down together,' Innes explained."

feldhaus writes "The BBC reports that the first beams for over one year have been successfully sent around the complete circumference of the Large Hadron Collider. Engineers do not yet have a stable circulating beam but they hope to by 0600 GMT on Saturday."

Every 15 Earth years, Saturn has its equinox — the time during which its rotational axis is perpendicular to the rays from the sun, so that the sun is always directly "overhead" of Saturn's equator. This is significant because Saturn's rings orbit over the equator, so during the equinox, light from the sun hits them edge-on. This means that any objects wider than the rings, or orbiting above or below them, cast long shadows and are much easier to see. For the first time, we're able to get detailed images of these objects, thanks to Cassini. A moonlet, perhaps 1,300 feet in diameter, has been discovered in the B-ring, and the Bad Astronomy blog points out another object that seems to be bursting through the F-ring. Quoting: "The upward-angled structure is definitely real, as witnessed by the shadow it's casting on the ring material to the lower left. And what's with the bright patch right where this object seems to have slammed into the rings? Did it shatter millions of icy particles, revealing their shinier interior material, making them brighter? Clearly, something awesome and amazing happened here.
