It’s not often that a military advertises a weapon on what it doesn’t do, but at the Africa Aerospace and Defence exposition in Pretoria, South Africa, that’s exactly what Chinese arms manufacturer Poly Technologies did. The “Shoulder-Launched Rocket with Low Collateral Damage” is a weapon designed to give troops all the utility of a wall-piercing explosion, with a lot less of the accidental casualty downside.
Among the 2.5 tons of cargo that's set to go up to the International Space Station this weekend, there will be five mice with a particular genetic mutation. The mice lack a gene that normal mice have, called Muscle Ring Finger 1, or MuRF-1 (rhymes with Smurf). Scientists are hoping the missing gene will keep those mice healthier in space than their five ordinary compatriots that will be riding up with them.
Picture this: You're on a cross-country road trip with your kids, passing through some dusty corner of Nevada in your self-driving 2030 Chevrolet Lumina. Your car then sends an invisible message across the desert: Three passengers. Two in child seats. Sixth hour without a break. A distant server whirrs, combs through a database of your and your kids' past online behavior, and beams a command back to your car. A grinning clown dances across your windshield and a familiar jingle plays. "McDonalds!" your kids squeal. Suddenly you have lunch plans.

Of course, it wasn’t long before reality sank in. I’m not really part of this proverbial “we.” The rides are for NASA astronauts only, not for us mere mortals, fated to only walk on one planet for the rest of our lives. My excitement soon became mixed with a reinvigorated longing to explore the celestial frontier.
A team of twenty students at the Eindhoven University of Technology in the Netherlands entered the Bridgestone World Solar Challenge 2013, a six-day solar race across Australia’s Outback, in the new Michelin Cruiser Class. Practicality was paramount for these entries, though energy use, payload capacity, and speed counted as well. The question to answer, according to Jordy de Renet, one of Stella’s drivers, was, “Do you want it in your daily life? Would you want to take it to get groceries?”
You can build a lot of cool stuff with LEGO. It's also really painful to step on. But at Brickworld events, the skills and projects are taken to a whole new level. It might not be super useful to move balls endlessly around a track, but there shear variety and ingenuity of the methods are amazing.
Here's a refresher from middle school science class: An asteroid is a huge rock tumbling through the solar system, and that's pretty much all it looks like--a big rock. Meanwhile, a comet is a ball of ice and dust that has a long bright tail, which is caused by the Sun blasting that ice and dust off of the comet's surface as it zooms around.
