Australian Popular Science Newshttp://www.popsci.com.auLatest news from www.popsci.com.auMon, 1 May 2017 06:35:55 +100010The US Navy is designing safer batteries, because no one wants a fire at sea Our smartphones and other gadgets are powered by lithium-ion batteries, but as companies like Samsung know all too well, those charge-holders can be flammable under the wrong conditions. The hazards of lithium-ion batteries are also a concern for another group, one with a strong incentive to keep fires at bay: the U.S. Navy. Now chemists at the U.S. Naval Research Laboratory (NLR) have announced a new battery technology that they say is both safe and rechargeable, and could make its way into electric vehicles, bikes, or ships.http://www.popsci.com.au/tech/military/the-us-navy-is-designing-safer-batteries-because-no-one-wants-a-fire-at-sea-,459842Fri, 28 Apr 2017 10:50:32 +1000Scientist discover: it take 12 seconds to poopIt's not clear why dogs look at us when they poop, but it's possible they're trying to make sure you're on the lookout while they're in a vulnerable position.

After years of orbiting around the Saturn system and collecting some stellar scientific data, the spacecraft is on a path of certain destruction: on Sunday, the probe officially began the last leg of its mission, which will eventually bring it so close to Saturn that the planet's gravity will drag it down and burn it to vapour.http://www.popsci.com.au/space/a-spacecraft-just-flew-between-saturn-and-its-rings-for-the-first-time-ever8212and-there-are-pictures,459839Fri, 28 Apr 2017 10:50:31 +1000China's new aircraft carrier suggests a powerful navy in the worksThe Type 001A aircraft carrier, maneuvered to pierside by tugboats, will be fitted for the next or so with electronics and self defense systems, before being commissioned, followed by embarking an air group, to get up to speed in order to enter service.http://www.popsci.com.au/tech/military/chinas-new-aircraft-carrier-suggests-a-powerful-navy-in-the-works,459838Fri, 28 Apr 2017 10:50:31 +1000Bricks made from fake Martian soil are surprisingly strongIf you think building a house on Earth is hard, try building one on Mars. Every pound of material that we ship to the red planet will cost thousands of dollars, so scientists want to construct our future martian colonies out of locally sourced materials&#8212;namely, martian dirt.

The insects display those incredible hues thanks to scales on their wings. Those scales are made up of crystals, which are made up of a sugar molecule called chitin (the same stuff that makes up insect exoskeletons and mushrooms). The tiny crystals on butterflies' scales are called gyroids. They're of interest to biologists, but also to materials scientists. Butterflies' gyroids are for more tiny and precise than anything made by humans today.http://www.popsci.com.au/science/nature/scientists-are-puzzling-out-how-butterflies-assemble-their-brightly-colored-scales-,459690Thu, 27 Apr 2017 09:25:30 +1000Smartphone-controlled cells release insulin on demand in diabetic micePeople with diabetes often need to inject themselves with insulin on a daily or weekly basis.

Like, a lot. In fact, humans have been hanging out with doggos for at least 15,000 years or so, and likely a lot longer. Over the course of that long, mutually beneficial friendship, we've done a lot of strange things to our four-legged companions, controlling their reproduction to coax them into breeds that suit our (sometimes absurd) needs.http://www.popsci.com.au/science/nature/new-study-asks-how-your-favorite-doggos-came-to-be-,459525Wed, 26 Apr 2017 10:19:46 +1000Apparently the end of the world is going to make us all work out moreHere's the tiniest silver lining to the abysmally black cloud that is climate change: it might finally get Americans to exercise, according to a study released today in the journal Nature Climate Change.

Physics has the answer. Learning to crack an egg is a culinary rite of passage. Do it correctly, and the shell swiftly breaks, spilling the liquid contents out in one fell swoop. Do it wrong, and you end up with yolk on your hands and shell in your bowl. Luckily, science has hatched a formula that is nearly infallible. All it requires is knowledge of a few basic physics principles.http://www.popsci.com.au/science/whats-the-best-way-to-crack-an-egg-physics-has-the-answer-,459521Wed, 26 Apr 2017 10:19:44 +1000These caterpillars chow down on plastic bags Plastic bags are nothing if not persistent&#8212;even when we want them to disappear.

But there'll be no relaxing days on the beach for this old spacecraft; instead, it will go out in a blaze of glory.

He and colleagues Chad Brown (no relation) and James Hashmi were bidding on a record pressing machine. It was the only one the new entrepreneurs could find, and it was in the middle of nowhere&#8212;in Russia. No one knew if it worked, or could even be refurbished back into working order. Yet, the bidding was feverish: Brown's team walked away, but the press ultimately sold for some $60,000.http://www.popsci.com.au/gadgets/viryls-new-record-presses-are-the-first-in-30-years,459360Mon, 24 Apr 2017 11:54:49 +1000Why are the measles coming back?We eliminated measles in the U.S. in 2000.

It's an inevitable&#8212;but crucial&#8212;step in the development of smart home virtual assistants. The new skill means that different people in a household will be able to ask the Google Assistant questions about what's on their calendar, or what their commute looks like, and the Home device will know who is speaking to it and give tailored responses.

There's no question about that. And they're jam-packed with essential vitamins. But like any food, there's perhaps a million ways one can eat them: raw, steamed, baked, and even fried.

"Science fiction plague," perhaps, or "dear god, why have you forsaken us," or "put that thing back where it came from, so help me."

For centuries, the caves of Afghanistan have made it difficult for outsiders to control the country. But in the early 21st century, the United States considered developing a brand new weapon to nullify these ancient defenses. The &#8220;Robust Nuclear Earth Penetrator&#8221; was an earthquake in a can, a nuclear bomb designed to seal the caves once and for all.http://www.popsci.com.au/tech/military/the-bunkerbusting-nuclear-bomb-that-almost-was-,458621Tue, 18 Apr 2017 11:12:44 +1000Google is using AI to help humans and computers communicate through artGoogle went big on art this week.

The wide angle lenses introduce unpleasant distortion, and the small camera sensors can't produce those blurry backgrounds we see in higher-end portraits.

Climate change is altering the jet stream, making severe turbulence more likely. The study builds on earlier work which found that climate change would lead to bumpier airplane rides. What makes the new research unique is that it quantifies how much different kinds of turbulence will increase&#8212;59 percent in the case of light turbulence, a 94 percent increase in moderate turbulence, and 149 percent increase in severe turbulence.http://www.popsci.com.au/tech/aerospace/climate-change-could-make-severe-turbulence-even-worse-,457502Fri, 7 Apr 2017 11:22:48 +1000
