The &#8220;Shoulder-Launched Rocket with Low Collateral Damage&#8221; is a weapon designed to give troops all the utility of a wall-piercing explosion, with a lot less of the accidental casualty downside.http://www.popsci.com.au/tech/military/china-shows-off-less-deadly-rocket-launcher,392318Sat, 20 Sep 2014 08:53:09 +1000Mousetronauts To Live In Space For the Longest Stretch YetAmong 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.http://www.popsci.com.au/space/space-travel/mousetronauts-to-live-in-space-for-the-longest-stretch-yet,392317Sat, 20 Sep 2014 08:53:05 +1000Self-Driving Cars: A Marketer's Dream?Picture this: You're on a cross-country&#160;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:&#160;<i>Three passengers. Two in child seats. Sixth hour without a break.</i> 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.http://www.popsci.com.au/tech/cars/selfdriving-cars-a-marketers-dream,392316Sat, 20 Sep 2014 08:53:01 +1000 The Week In Drones: Robots Piloting Robots, Indiana Drones, And MoreHere's a roundup of the week's top drone news: the military, commercial, non-profit, and recreational applications of unmanned aircraft.http://www.popsci.com.au/robots/drones/-the-week-in-drones-robots-piloting-robots-indiana-drones-and-more,392315Sat, 20 Sep 2014 08:52:56 +1000Next Week Is Climate WeekNext week is <a href="http://www.climateweeknyc.org/" target="_blank">Climate Week</a> in New York City.

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.http://www.popsci.com.au/space/where-is-this-comets-tail,392217Thu, 18 Sep 2014 09:55:59 +1000Texas Considers Textbooks That Contain Climate Change DenialOh Texas.

That push and pull forms the underlying structure of all matter. Light particles, or photons, do not typically interact with one another, according to Dr. Andrew Houck, a professor of electrical engineering at Princeton and an author on the study. The trick of this research was forcing them to do just that.</span>http://www.popsci.com.au/tech/computing/light-forms-crystallike-structure-on-computer-chip,392214Thu, 18 Sep 2014 09:55:47 +1000Big Pic: A Texas-Sized Algae Bloom<a href="http://www.nature.com/ncomms/2014/140909/ncomms5862/abs/ncomms5862.html" target="_blank">A paper in <em>Nature Communications</em></a> reports that a phytoplankton named <em>Noctiluca scintillans</em>&#160;has invaded a dead-zone off the coast of India, where it's threatening to disrupt natural foodchains as well as the local fishing industry.http://www.popsci.com.au/science/nature/big-pic-a-texassized-algae-bloom,392213Thu, 18 Sep 2014 09:55:41 +1000Spooky Action In Threes: Physicists Entangle Three Particles Of LightAs if it weren't hard enough already to imagine it in twos, physicists have entangled three photons with each other. Entanglement is a counterintuitive quantum physics phenomenon, in which a particle influences all the others with which it's entangled -- even if the particles are far apart. If one particle is in one state, for example, the others might be in the same state. In this case, however, each photon, which is a particle of light, had the same polarization -- either horizontal or vertical.http://www.popsci.com.au/space/cosmology/spooky-action-in-threes-physicists-entangle-three-particles-of-light,392212Thu, 18 Sep 2014 09:55:37 +1000Help Scientists By Marking Penguins In PicturesCheck out <a href="http://www.penguinwatch.org">this latest citizen-science project</a>.

Almost immediately, Tindie began attracting favorable attention from the indie hardware community&#8212;and then expanded from there. Today, around 600 inventors sell more than 3,000 different hardware products, which have shipped out to more than 80 countries around the world. Some customers are hobbyists like Petrone, but others are large entities like the Australian government, Google and NASA.

A new report finds that ozone-depleting substances in the atmosphere are down by 10 to 15 percent, and that the ozone layer is by and large getting thicker.http://www.popsci.com.au/science/nature/the-ozone-layer-is-on-the-mend,392032Fri, 12 Sep 2014 09:41:53 +1000
