China Electronics Technology Group Corporation (CETC), China's foremost military electronics company, has announced that its scientists have tested a quantum radar to the range of 100km, beating out known American and German competition by 500%. This is a significant claim to make, as a quantum radar would theoretically be able to detect stealth aircraft at long ranges.http://www.popsci.com.au/tech/military/china-says-it-has-quantum-radar-what-does-that-mean-,438366Wed, 28 Sep 2016 10:21:10 +1000Watch Elon Musk Present His Plans For Humanity's Multi-Planetary FutureElon Musk probably writes "try to save the world" at the top of his to-do list every day, above running companies that are revolutionizing energy, transportation, and space travel.

Not only is it the smallest officially recognized planet in our Solar System, but it's also shrinking. In a study published in Nature Geoscience, new analysis of photos taken by NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft show distinct landforms that indicate the planet is still contracting as it slowly cools down from its molten early years at the start of the Solar System.http://www.popsci.com.au/space/photos-suggest-mercury-is-actively-shrinking-,438303Tue, 27 Sep 2016 11:40:10 +1000Now You Can Own A Transformer In Real LifeAs children, many of us sat in front of the television on Saturday mornings, wishing the characters from fantasy worlds would inhabit our own. Now, a Turkish startup called <a href="http://www.letrons.com/index_eng.html?dom=pscau&amp;src=syn" target="_blank">Letvision</a> is working to make that dream a reality. They recently unveiled a Transformer-inspired machine that starts out as a mild-mannered BMW coupe, and with the work of hydraulics and servos it reveals its secret identity as a massive humanoid robot.http://www.popsci.com.au/gadgets/now-you-can-own-a-transformer-in-real-life,438302Tue, 27 Sep 2016 11:40:10 +1000DroneSeed Company Could Replant Forests After Forest FiresAutomating forestry is an uphill battle. Trees grow well on slopes and steep inclines, which are difficult for farming equipment, adapted as it is to sweeping, gentle plains. This is especially hard for the replanting part of responsible forestry, where seedlings need deliberate, tender care so they can begin to replace their fallen predecessors. This is, right now, a human intensive process, but startup DroneSeed wants to turn over the entire process to, you guessed it, drones.http://www.popsci.com.au/science/nature/droneseed-company-could-replant-forests-after-forest-fires,438301Tue, 27 Sep 2016 11:40:10 +1000Hubble Finds New Evidence Of Water Plumes On EuropaHubble's view of huge plumes of water vapor in 2013, data shown superimposed on a photo of Europahttp://www.popsci.com.au/space/hubble-finds-new-evidence-of-water-plumes-on-europa,438300Tue, 27 Sep 2016 11:40:10 +1000A Devil Frog Puked Up This New Ant Species Out of the belly of a bright orange frog, a mysterious species of ant appears.http://www.popsci.com.au/science/nature/a-devil-frog-puked-up-this-new-ant-species-,438299Tue, 27 Sep 2016 11:40:09 +1000Watch A UPS Drone Deliver Medical Supplies To An IslandUPS has over 100,000 cars, vans, tractors, and motorcycles in its delivery fleet, and over 500 jets owned or chartered. That's a massive fleet by any metric, and one with a tremendous amount of reach for the delivery giant. Yet it's a fleet with one major limitation: the jets need large runways to land, and the automobiles are all limited by land. This is fine for people on the mainland, but what if UPS wants to deliver something to a small island, one without the space for a runway or ferry? Drones. Drones are the obvious answer.http://www.popsci.com.au/robots/drones/watch-a-ups-drone-deliver-medical-supplies-to-an-island,438298Tue, 27 Sep 2016 11:40:09 +1000Riding A Roller Coaster Could Help You Pass Small Kidney Stones Every year around Spring Break there is a mass migration in which flocks of families from mid-Michigan flee the winter cold and head South, down to Orlando, Florida and the many theme parks there.

Everything looked perfect until the rocket started vibrating in flight so hard it was almost bouncing up and down. The so-called pogo effect (it's almost like the rocket is bouncing on a pogo stick) increased g-forces in the spacecraft and shook the rocket's frame so hard that loose structural panels on the lunar module adapter section fell off. The irregular launch also destroyed the flight path, leaving the spacecraft in a highly elliptical orbit rather than the planned circular one. Luckily Apollo 6 was unmanned, but the problem was bigger than one mission. NASA had spent years solving the pogo problem only to see it return, this time threatening manned lunar missions.http://www.popsci.com.au/space/space-travel/how-little-vibrations-break-big-rockets,438295Tue, 27 Sep 2016 11:40:07 +1000Exploring Obama's Seafloor Canyons by Mini&#160;SubAlong the walls of Oceanographer Canyon, fish dart in and out of colorful anemone gardens and sea creatures send up plumes of sand and mud as they burrow.
