Try Honey TastingInside a lofty brick building on a quiet Brooklyn street, thirty of us sat around a horseshoe-shaped table with plates of grapes, almonds, bread, and pungent, sweaty cheese. Between every group of four sat six wine glasses, which we held to the light and shoved our noses into, like you would at any wine tasting. Except instead of wine, these glasses were full of honey. By the end of the night, I decided I much prefer honey tastings, if we're going to be honest.http://www.popsci.com.au/science/wine-tasting-not-for-you-try-honey-tasting,420216Mon, 30 May 2016 10:16:52 +1000DARPA Urgently Wants A Space Plane It Can Fly Day After DayThe Pentagon is building another space plane. It already has one, the Air Force's secretive X-37B, but DARPA, the Pentagon's future-focused project's research agency, wants another. This new space plane is the XS-1, and it has a deeply ambitious goal: deliver 3,000 pounds to orbit, every day, at a cost of $5 million for delivery.http://www.popsci.com.au/space/darpa-urgently-wants-a-space-plane-it-can-fly-day-after-day,420215Mon, 30 May 2016 10:16:52 +1000New Test Could Tell Whether Comatose Patients Will Wake UpTo determine whether a patient that's in a coma will awaken again, scientists have devised a new test using positron emission tomography (PET).http://www.popsci.com.au/science/medicine/new-test-could-tell-whether-comatose-patients-will-wake-up,420214Mon, 30 May 2016 10:16:52 +1000Dr. Heimlich Does The HeimlichAfter more than three decades, the doctor who invented a maneuver to save people from choking got to use it himself.http://www.popsci.com.au/science/medicine/dr-heimlich-does-the-heimlich,420213Mon, 30 May 2016 10:16:52 +1000Here Come The Laser HelicoptersWhen all you have is a gun and a bunch of missiles, every problem looks like something to blow up. The Army's Apache helicopters are very good at blowing stuff up, but there are times when they need more precision.

NASA used the spent spacecraft for science, directing these modules for controlled crashed into the Moon. These crashes caused moonquakes, and scientists measured the vibrations moving through the Moon and found it rings like a bell.http://www.popsci.com.au/space/does-the-moon-sound-like-a-bell,420210Mon, 30 May 2016 10:16:51 +1000In Study, Beer Drinkers Found To Be Less Alzheimer's-ProneA <a href="http://www.ncbi.nlm.nih.gov/pubmed/27218874?dom=pscau&amp;src=syn" target="_blank">study of 125 males</a> found less overall aggregation of amyloid beta, the main component of the plaque connected to Alzheimer's disease, in beer drinkers than in non-beer drinkers.http://www.popsci.com.au/science/medicine/in-study-beer-drinkers-found-to-be-less-alzheimersprone,420209Mon, 30 May 2016 10:16:51 +1000Canadian Robot Shines Light On Controversial New BroomCurling seems like a low-tech sport: just a broom, a heavy stone, and a sheet of ice. However, new technologies have led some curling broom companies to innovate. But there are concerns that new directional fabrics and broom designs could be giving players an advantage--they're just too good to use in competition. So much so that they're often dubbed "frankenbrooms" and have been <a href="http://www.bbc.com/news/uk-scotland-34920568?dom=pscau&amp;src=syn" target="_blank">banned</a> from the sport.http://www.popsci.com.au/robots/canadian-robot-shines-light-on-controversial-new-broom,420208Mon, 30 May 2016 10:16:51 +1000Watch This Woman Climb A Skyscraper With A Vacuum CleanerVacuum cleaner-wielding superheroes are about to be taken a lot more seriously.

First, they needed to work together with a fellow robo roach to climb over things. Now, a collaboration between Seoul National University in South Korea and UC Berkeley has developed a roach that goes leaps and bounds beyond that. <em>IEEE Spectrum</em> <a href="http://spectrum.ieee.org/automaton/robotics/robotics-hardware/jumproach-robotic-bug?dom=pscau&amp;src=syn" target="_blank">reports</a> that the researchers showed off their appropriately named JumpRoACH at the IEEE International Conference on Robotics and Automation in Stockholm this month.http://www.popsci.com.au/robots/robot-roach-can-jump-up-to-five-feet-high,420201Mon, 30 May 2016 10:16:51 +1000This Drone On A Leash Could Guard Army BasesSmall drones are inefficient birds. They fly for short bursts of time, and get thrown about in the wind. That's not great for anyone hoping to use a drone as a hovering sentry, but there's a better way: tethers. Put a leash on a drone, and suddenly it's a flexible flying watchdog, able to peek up high and then recharge safely in its mechanical nest.http://www.popsci.com.au/robots/drones/this-drone-on-a-leash-could-guard-army-bases,420200Mon, 30 May 2016 10:16:51 +1000Dubai Has 3D-Printed An Entire Building3D printing is still a young technology, but when you can use it for important tasks like making gummy snack figures of yourself, or building a home, it's no longer in its infancy.

Theorized in the 1930s and first built and used in the 1940s, these weapons shape the outer bounds of human conflict: they're powerful, they're terrible, there is not much we can do about them, and they're waiting to end the world the moment an equal number of Russian nukes launch. Should that fateful day come to pass, we'll initiate the apocalypse with another similarly anachronistic technology: floppy disks.http://www.popsci.com.au/tech/military/yes-the-pentagon-still-uses-floppy-disks-for-nuclear-launches,420197Mon, 30 May 2016 10:16:51 +1000GoDaddy Launched a Tinder for Startups, For Some ReasonHandling dating the way you handle business decisions might seem cold, but GoDaddy might be onto something by flipping that formula around.http://www.popsci.com.au/tech/godaddy-launched-a-tinder-for-startups-for-some-reason,420196Mon, 30 May 2016 10:16:51 +1000Common Infections Might Be Causing Alzheimer's DiseaseThe root cause of Alzheimer's, a progressive disease that as of 2013 <a href="http://www.cdc.gov/aging/aginginfo/alzheimers.htm?dom=pscau&amp;src=syn" target="_blank">affects</a> some 5 million Americans, is still not completely understood.

The totalitarian communist Democratic People's Republic Of Korea, long isolated from the rest of the world, tightly controls what media people inside the country can access. For decades, human rights activists and others have tried to get messages into the country, which is difficult because of the the heavily fortified demilitarized zone between North and South Korea.http://www.popsci.com.au/robots/drones/drones-bring-flash-drives-with-western-movies-to-north-korea,420090Thu, 26 May 2016 09:21:54 +1000Could There Be A Fifth Fundamental Force Of Nature?It's long been accepted by physics that nature has supplied us with four fundamental forces. Gravity holds the planets and galaxies together, and the electromagnetic force holds us and our molecules together. At the smallest level are the two other forces: the strong nuclear force is the glue for atomic nuclei, and the weak nuclear force helps some atoms go through radioactive decay. These forces seemed to explain the physics we can observe, more or less.http://www.popsci.com.au/science/could-there-be-a-fifth-fundamental-force-of-nature,420089Thu, 26 May 2016 09:21:54 +1000Can Trees Make Clouds Form?The &#8220;pristine&#8221; atmosphere our planet had before the industrial revolution may have been cloudier than expected, <a href="http://home.cern/about/updates/2016/05/cloud-shows-pre-industrial-skies-cloudier-we-thought?dom=pscau&amp;src=syn" target="_blank">reports</a> the European Organization for Nuclear Research (CERN).http://www.popsci.com.au/science/nature/can-trees-make-clouds-form,420088Thu, 26 May 2016 09:21:54 +1000American Special Forces Have A New Stealth MotorcycleNicknamed "silent professionals," America's Special Operations Forces exist on the edge of war, moving behind and around front lines, preparing battles behind the scenes.
