About 190 million years ago, during the Early Jurassic Period, a vast desert larger than the Sahara covered much of what is now Utah, Wyoming, Colorado, New Mexico, Arizona, and Nevada. Given that Jurassic time was the "Age of Dinosaurs," it's not surprising that fossil evidence of the great reptiles would show up there now and then. But recently, geologists from the University of Utah uncovered an exceptional find -- a large concentration of dinosaur tracks and rare tail-drag marks.
2 things: 1. "more than 1,000, and maybe even thousands" Is this the rough draft? 2. Some pics of the tracks, foot prints, and tail drags would be nice.
About 230 years ago, molten lead that rained from the sky—historically something to avoid at all costs—became a clever new way to manufacture an important commodity: shotgun ammo. Precisely round pellets fly straighter, but casting each in its own 1/8-inch mold isn’t exactly mass production. In space, making them would be easy. In zero gravity, surface tension pulls any liquid into a sphere, the shape with the least surface area for a given volume.
What's obvious is that andrewl did not read the article. He could get high enough for the shot to cool properly, thus when it hit the water it deformed. As for a use, sling shot ammo.
I’m in awe of NASA as much as the next guy. But, as the venerable space agency toasts its golden anniversary next month, I just can’t escape the Grouse in me. Sure, the last 50 years of extra-terrestrial poking around have been filled with innovation and breakthrough. Unfortunately, there’s also been a lot of crap—specifically on the consumer side of things. Why does it seem like only the lamest, most cheeseball products on the market claim to be NASA-approved?
Again....can you guys try proof reading your articles before posting them.
Scene: A Royal Air Force station in Great Britain during World War II. Two medics, Tom and Fred are enjoying tea and toast. An officer arrives and orders the medics go out with a stretcher to retrieve a captured German pilot who was wounded when he ejected from his plane over British territory. Tom: Dash it all, Fred, doesn’t this bloody Nazi pilot look just like the Nazi with the broken femur we just sent back through the POW exchange a few weeks ago? How could he be up and flying again so soon with an injury like that? He should have been bedridden with his leg up in traction for months! Fred: Crikey, old chap, I do believe you’re right! [Addresses the Nazi pilot] Here now, tell us how you managed to get up and about so soon after cracking your femur? German Pilot: Nein. Tom: Come on, old boy, tell, are doctors in Germany so special they’ve got you cured already?
Nice article, but next time get your buddy to proof read it first. Or maybe that's what you did, so next time let some one else proof read it.
At the starting dock of the Olympic triathlon trials, the expression on Andy Potts’s face seems to say I will kill you with my eyes. As the starting gun fires, he plunges into the Black Warrior River in Tuscaloosa, Alabama, and, in a burst of white foam, quickly pulls ahead of nine rivals. The second-ranked Hunter Kemper manages to hold pace with Potts for a few minutes, then drifts back into third place.
He did not make it to the Olympics.
World of wires got you down? Clear the clutter with your very own fire-proof gadget charging station. Editor Mike Haney shows how a power drill and some tape can transform a bread box into a pint-size panic room just for chargers.
How is this less clutter than three small devices. Most people would pu the strip plug behind their desk so the only thing showing would be the the 3 little plug ends. I also agree with the choice of the drill bit. Maybe the guys from Popular Science should call the guys over at Popular Mechanics next time they need to use some tools.
Two years ago we showed you Boston Dynamics' incredible BigDog—one of the world's most ambitious legged robots—being developed for DARPA and the U.S. Army. With its advanced system of hyper-responsive hydraulic joints and a suite of sensors, accelerometers and gyroscopes, the BigDog's most stunning achievement is it's ability to walk, climb and maintain its balance on diverse terrain, even after slipping on ice or receiving a kick to one side. All while carrying several hundreds of pounds of supplies on its "back."
CREEPY!!!!
I have a confession to make: I am an addict. Im strung out, my friends, literally—surrounded by the paraphernalia of my drug of choice, electricity. My apartment is a sickening jumble of daisy-chained power strips and extension cords, all supporting my particular addiction to wall warts—those power-squandering, space-wasting, chunky black power adapters used to juice my gadgets. Im not about to give up all my electronic gear—no sir, thats not an option—so Id like to offer a compromise. A methadone treatment, if you will allow me to stretch this already thin metaphor.
The anti-parasitic draw devices can be easily installed inline with the elctrical circuits in your home. The you could color code the outlet on your wall. One plug for devices that require constant power, and one plug that can sense when and if power is needed.
