Sic Transit Gloria Futurae

Since speciÿcity is so important in science, I’ll point out it’s only this separate Australian edition of Popular Science that will cease publication, while the 147-year-old institution will continue to steam boldly in the direction it has always travelled: toward the future. After you read this, you’ll be able to get your PopSci ÿx from popsci.com, where familiar names will continue to bring your all the futuristic news and long-form journalism you’ve come to expect. Just delivered in a more futuristic way! Australian Popular Science began publication in 2009, so it’s worth reflecting on how much the world has changed since then. Back in 2009, the cutting-edge of smart-phone tech was the iPhone 3GS. Intel was still two years away from introducing the “ultrabook” speciÿcation for super-thin notebook PCs. The…

CHINA’S MOON DYNASTY

The Chang’e 3 Moon lander touched down on Mare Imbrium on 14th December 2013, and to this day still responds to commands from China’s mission control. It makes Chang’e 3 the longest-operating lander in the history of lunar exploration. A rover, named Yutu (or “Jade Rabbit”) worked for two years, but lacking Chang’e 3’s shielding, it eventually succumbed to radiation. The lander’s Lunar-based Ultraviolet Telescope remains a valuable tool for Chinese astronomers, and amateur radio operators can routinely pick up Chang’e 3’s signals. A NEW JADE RABBIT On the 3rd of January 2019, Chang’e 4 landed on the far side of the Moon, in the South Pole-Aitken Basin. Three years later than planned, it successfully deployed the Yutu-2 rover. China’s exploration of the Moon goes on.…

2019: Year of the Impossible Burger

VEGAN BEEF TARTARE IS A DIFFICULT CONCEPT TO visualise. It conjures images of a pile of beans, or perhaps a slab of tofu served with some nicely charred crostini. But at the 2019 Consumer Electronics Show in Las Vegas, Impossible Foods showed off its new plant-based ground beef replacement. And we had to be the judge. By offering a selection of foods from traditional sliders to the ambitious tartare, Impossible Foods at least showed its concoction has some versatility. And thanks to a change in formula, the new Impossible Burger 2.0 goes beyond simple patties and aims to take on ground beef with every recipe, from lasagna to tacos. The fi rst tastes are very promising. Here‛ our take. WHAT’S NEW? Back in 2016, the original Impossible Burger debuted as…

FORESTRY IS THE MOST DANGEROUS CIVILIAN JOB IN THE US, thanks to hazards like heavy machinery and falling limbs (after you sever them with the heavy machinery). The controlled environment of your backyard can be a safer place for you to take down old trees and chop up the pieces. You might not aspire to be Paul Bunyan, but you can still grab tools—similar to what lumberjacks use in competitions— to become a suburban log slayer. 1 Axe The 2.7-kg head on the Precision Competition Chopping Axe has a 190-mm hand-sharpened edge. The steel slices deep into timber without sticking, and it absorbs vibrations. 2 Gloves A pair of Husqvarna Functional Chain Saw gloves provides extra protection for your nonsawing hand. The left side has two layers of goat leather…

IN AN IDEAL WORLD, EVERYONE WOULD WALK AROUND WITH a Batman-style utility belt. When peril presents itself, we’d have grappling hooks, smoke screens, or whatever gizmos necessary to POW! our way to safety.

The Fast and the Flurry-est

YOU DON’T NEED TO HURL YOURSELF OFF A CLIFF OR OUT OF A PLANE TO GET A TASTE of adrenaline. This winter, ›ind a hill, put on your puffiest pair of fanny-protecting snow pants, and grab a slippery rig for a dose of pure, gravity-powered fun. Ranked here from fastest to slowest, these light and aerodynamic sleds will carry you down slopes and around slick corners, and possibly even propel you into fantastic yard-sale-style wipeouts. Ask your pals to record your ice capades in slow motion to relive later, hot cocoa in hand. 1 The Yukon Hammerhead Pro HD flies across the snow thanks to its 110-mm-wide rear skis: They create less friction than a flat-bottom ride, and won’t dig into terrain like classic skinny rails will. 2 Flop onto…

FOR SQUISHY BABIES, CARS PRESENT A FATE WORSE than nappy rash. Securing kids during a ride took decades to perfect. But ÿguring out the best way to strap in wee ones is worth it: The right restraint can reduce the risk of death in a crash by 70 per cent. Here’s how child safety seats went from precarious to secure. 1920s DIY restraints The ÿrst cars prioritised speed and freedom over safety. Parents who needed to contain their children used patchwork solutions, like threading their tykes through this cam strap and faux leather contraption. It’s useless in a wreck. 1930s Bunny Bear Company Early car seats resembled the simple highchairs you’d ÿnd at a dinner table. They elevated the child so they could see out the window but had no…

Dress for Distress

THE DUPONT TYCHEM 10000 HAZMAT suit is overkill for just about every situation. That’s the point. The getup blocks more than 320 nasty chemicals for at least 30 minutes. Some, such as the VX nerve agent (a deadly weapon), won’t breach it for eight hours or more, which is why ÿrst responders don the garments when wading into clouds of noxious death. Here’s how it keeps its occupants from melting. Shell The suit is a sandwich of materials. The middle layer is roughly 3-mmthick puncture-resistant polypropylene, and a coating on both sides includes dozens of plastic polymers. Each of those has its own protective responsibility, like stopping sarin gas. Visor The face shield gives rescuers a 220-degree ÿeld of view, and it leaves enough room for a scuba-style respirator to…

A Riderless Motorcycle?

WE ALREADY LIVE IN A WORLD OF SELF-DRIVING VEHICLES. Autonomous cars have a pretty clear function to offer: they can carry passengers from one place to another, with no driver required to do something old-fashioned like turn a wheel (or earn a paycheque). Auto-vans deliver groceries or parcels. Some clean the streets. So what, then, could possibly be the purpose of a riderless motorcycle? BMW demonstrated just that at the Consumer Electronics Show in Las Vegas, where a motorcycle with no human aboard drove across a parking lot, making tight turns left and right and cruising over the asphalt. When it came to a stop, its kickstand even deployed to catch it while it slowed down. This project has been in the works at BMW since 2014, and the goal…

Electric Love for Struggling Coral Reefs

ARTIFICIAL REEFS HAVE BEEN USED FOR several decades to encourage coral and other sea life to recolonise damaged ocean ecosystems. But with rising acidity and temperature, these organisms now need extra help - from an unexpected bit of technology. Back in 1996, it was discovered that electrifying a metal structure underwater caused calcium carbonate to accrete onto the bars, creating a substrate for coral larvae to establish new colonies. The electric current runs at several amps, but very low voltage, so it doesn’t hurt the animals at all. This technique remained patented and was expensive, but now the patent has expired, it’s open season: enterprising conservationists are now making their own electrified artificial reef systems. Which is how, off the coast of the island of Koh Tao, which is part…

Osiris and Bennu: A (Very Small) Love Story

WHILE NEW HORIZONS SOAKED UP most of the world’s thirst for space stories over the New Year, there was another success story worth unpacking: NASA’s OSIRIS-REx spacecraft finally entered asteroid Bennu’s orbit, after more than two years of hurtling through space toward the rock. On the afternoon of December 31, about 110 million kilometres away from Earth, Bennu broke the record for becoming the smallest object in space to have a human-made spacecraft in its orbit. This was not a routine operation for NASA. Trying to insert a spacecraft into the orbit of an object like Bennu is a fraught process. The team at NASA ended up having to account for hundreds of variables that could have derailed the entire thing. OSIRIS-REx currently travels in an elliptical orbit about two…

Osiris and Bennu: A (Very Small) Love Story

BEFORE THERE WAS NOTHING. Then, there was zero. So ubiquitous is the little oval, imagining life without it seems impossible. It’s the symbolic swim donut keeping maths, science, and the internet afloat. But it wasn’t always there. Accounting is an ancient profession. Sumer, the earliest known Mesopotamian civilisation, had a positional numbering system, so there was no need for placeholders. A subsequent empire, Babylon, had different demands, so its number-crunching class used two empty wedges to represent a number like 507. On the other side of the planet, the Mayan civilization came up with its own solution to a similar problem, placing a shell where modern mathematicians might place a 0. Some experts argue these wedges are zero’s ground zero, to borrow a phrase, but most academics attribute the invention…

The Science of the Four-Day Work Week

1:26: HENRY FORD SHOCKS INDUSTRY leaders around the world when he announces a five-day workweek for his Ford employees. “Just as the eight-hour day opened our way to prosperity in America, so the five-day workweek will open our way to still greater prosperity,” he writes, “it is high time to rid ourselves of the notion that leisure for workmen is either lost time or a class privilege.” At the time, unions and workers’ advocates had been jostling for reduced working hours for decades, as part of efforts to improve working conditions. However, Ford probably wasn’t thinking about his employee’s well-being when he made the switch, says John Pencavel, senior fellow at the Stanford Institute for Economic Policy Research. “He was more concerned, my guess, with preventing a possible unionisation,” and…

The Downside of the Gene Test

NOW WE LIVE IN THE AGE OF READILY available genetic testing, there are a lot of questions about how an in-depth test might help or hurt the health of a baby. A small study of newborns at Boston medical facilities examined what happens when you sequence an infant’s genome and tell parents at least some of what you find. Standard newborn screenings include checks for a small number of diseases, “and the criteria for including diseases is very strict,” says Alan Beggs, the study’s principal co-author and a professor of paediatrics at Harvard Medical School. The reasoning is that telling a family too much could potentially cause massive harm, either by unnecessarily distressing them over risks that may never turn into actual illness or by influencing medical decisions made in…

That’s a Spicy... Tomato?

SPICY FOOD IS POPULAR THE WORLD OVER, but one of the most popular active ingredients that makes food taste “hot ” —capsaicinoids, a group of chemical compounds — has useful properties beyond making food taste delicious. However, the plants that make capsaicinoids (the chili family, which botanists know as the genu Capsicum and which Australians know the larger, less-spicy variants of as... uh... capsicums) are small and have relatively low yields. But now a new paper in the journal Trends in Plant Science proposes an alternative: engineering tomato plants to produce capsaicinoids. What this means is that if all goes well, someday, you could enjoy a spicy tomato, or even be treated with capsaicinoids extracted from one. The paper, written by a group at Brazil’s Federal University of Viçosa, builds…

ALARM WILL SOUND

Steve Hill paces—patrols, really—in front of four projector screens in a classroom at Sandia National Laboratories, outside Albuquerque, New Mexico. He has close-cropped hair, a straight back, and a swaggering demeanour that together suggest he’s either former military or law enforcement. If you were unsure, your doubts dissolve when you hear him call dice “a tool to determine chance-based outcome.” The phrasing could be right out of a police report. So yeah, he used to be a cop. And now he’s a “high-risk security professional” at Sandia. On this May afternoon, Hill is standing in front of a room crowded with regulators, power-plant employees, research reactor runners, and other types who work with nuclear materials. They’ve come from all over the world to take the lab’s security training course. Through…

There’s no shortcut to a healthy diet. Eating balanced meals, tons of fruits and veggies, scant fatty red meats, and no processed junk food requires time and planning. Westerners ÿnd regimens with strict rules (no carbs! high fat! eat all the apples!) and big weight-loss promises far more alluring. Forty-ÿve million of us will try such a scheme each year, and many will go to extremes. These drastic plans aren’t just useless—most people gain back the kilos—but they also can damage our vital systems. We analysed how ÿve of today’s popular food trends throw the body out of whack. RAW This diet is exactly what it sounds like: You eat nothing cooked. Seem doable? Try downing an entire crudité platter, warns Christopher Gardner, a nutritional scientist at Stanford University. Taking…

A LONG HISTORY OF QUICK FIXES

VINEGAR In the 19th century, Lord Byron ate mostly taters and vinegar to stay slim; many still sip the apple-cider variety for the same effect. The logic: Acetic acid inhibits gut enzymes that digest starch. Dieters do slim down but also risk vocal-cord spasms, throat and stomach injuries, and tooth erosion. JUICE Liquid fasts trace their origins at least as far back as the Master Cleanse, a 1940s mix of lemon, cayenne, and maple syrup. Though modern cleanses do add real produce, straining out the flesh ditches the fibre and some vitamins. Results are fleeting: It’s all just water weight. MEAL BARS Restricting calories by swapping meals with cookies and bars has been popular since the 1960s. Pre-portioned foods are an easy way to check intake and slenderise, but one…

USE REAL CREAM People who eat full-fat dairy tend to have less cardiovascular disease. Nutritionists think this effect is probably the result of some combination of lipids being more filling and the microbes in cultured dairy boosting metabolism. EAT YOUR SWEETS It’s harder to fill up on liquid calories. Chewing prompts your body to decrease chemical hunger signals like the hormone ghrelin. Even if a slice of cake and a can of soda have equal sugar content, the confection is more likely to sate you. MAKE BREAD A CHASER Studies have shown that scarfing all your carbs last can cut blood-sugar spikes by 50 per cent compared to eating them first. Downing protein ups the production of insulin and incretin, which get your body ready to digest glucose. KEEP PASTA…

BORN [ NOT ] TO RUN

The brand-new Ford DeLuxe Fordor that Bonnie Parker and Clyde Barrow plucked from a Topeka, Kansas, driveway in 1934 was top-shelf: Cordoba gray paint, a big chrome grill, and a sumptuous leather interior. But what really attracted the car-savvy bank robbers lay beneath the hood—its 85-horsepower flat-head V8 engine. This new breed of machine was designed to give every American, opportunistic crooks included, a taste of speed. Every American except the cops. Depression-era police departments suffered from tight budgets and outdated tech; many officers still bumped around in old Model A’s, which had half the Fordor’s muscle. Criminals like Parker and Barrow could, of course, steal any ride they wanted, and they chose wisely. It took a Texas Ranger with his own V8, and a small-town cop who went through…

Want to raise an all-star? Let them play the field

Players are picking their games earlier and earlier. The average high-school athlete in 2016 had focused on a single sport since age 12, two years younger than those in college that same year. To compete, the logic goes, tykes need to focus on one thing as soon as possible, and do more of it: year-round practices and hours of drills. “Parents, athletes, and coaches do this because they think it’ll help them get to an elite level,” says Neeru Jayanthi, a leading researcher on young athletes and specialization at Emory University. But going hard on one skill can back›ire. Children who play one pastime year-round are about 40 percent more likely to get hurt than those who play more than one. Developing bodies are at particular risk for overuse injuries,…

Death in transit

EVERY PLANE CRASH GETS A NEWS SPOT, BUT THE 100-PLUS vehicular deaths that occur each day in the US rarely attract attention. Our familiarity with driving makes us feel safe. But operating a two-ton metal tank running on combustible fuel is risky. Even walking isn’t safe anymore: Pedestrian deaths are up, thanks in large part to the recent supremacy of the SUV, whose taller proÿle is more likely to land a fatal blow to the chest than a glancing one to the knees. Here, we show how those strikes ÿt into the 42,246 total US transit deaths in 2016.…

A Recipe for Rigor Mortis

DEATH CAN COME IN MANY forms, avocados included. If we can stomach enough of them, many of our daily foods are lethal. Down 30-plus glasses of water in a few hours, for instance, and you’ll do yourself in. (One major cause of MDMA-related deaths: water intoxication caused in part by drug-induced extreme thirst.) Of course, the human stomach usually doesn’t hold much more than four cups, but the toxic effects of overindulgence can build up as your intestines move the food along. Here’s how much you’d need to eat of a few foods to flirt with fatality. NUTMEG Eat as little as 6.5 teaspoons of this holiday spice to get a 12-hour high (and a two-day hangover), thanks to the psychoactive chemical myristicin.

One very deadly day in April

IN 2011, AN OUTBREAK-NOT OF DISEASE, BUT OF TORNADOES - SLAMMED THROUGH A LARGE swath of the Southern and Eastern U.S. The region saw 64 individual twisters on April 25, and another 50 the next day, but the worst still lay ahead. A head-spinning 199 tornadoes touched down on April 27, killing 316 and injuring almost 3,000. To compare this cluster to others, meteorologists use the Destruction Potential Index. DPI is the sum of each individual storm’s destructive capacity, which weather-folk quantify by multiplying each tempest’s wind power by the area it hits. April 27’s outbreak reached 21,980. That’s three times the next-most devastating event in 2010. Disasters like these are getting worse. From 1954 to 1963, the average outbreak—a sequence of six or more F1 or greater tornadoes that…

But isolate the stripes that make up the skulls, and you’ll find neither skull has purple bones; in fact, all the bones are the same color.

The pigments morph because of the Munker-White illusion, which shifts the perception of two identical color tones when they’re placed against different surrounding…

TALES FROM THE FIELD

COLLECTIONS Peril in the Lab Sure we expect scientists to encounter hazards out in the field. But laboratories aren’t safe havens either. We asked researchers about the most dangerous things they work with. 1 Liquid helium JENNY ARDELEAN, GRADUATE STUDENT IN MECHANICAL ENGINEERING AT COLUMBIA UNIVERSITY To study the intrinsic properties of materials like atomically thin semiconductors, we need to get rid of heat, which causes subtle vibrations and makes our data fuzzy. We use liquid helium to cool substances to minus 233°C, a bit warmer than space. Our lab pipes it through a closed system to avoid having to transfer—and risk spilling—the expensive liquid. If that happened, the helium could evaporate, burn off your skin, or displace oxygen so you’d suffocate. 2 High-powered laser DONALD UMSTADTER, DIRECTOR OF THE…

A cure for mosquito-borne illness EMMÜELL GAUS VIA FACEBOOK EVERY YEAR, MOSQUITOES cause an estimated 400,000 malaria-related deaths. But disease-battling scientists such as Omar Akbari, a molecular biologist at the University of California at San Diego, say there’s a way to stop it: Get rid of the offending critters altogether. The DNA-editing tool CRISPR allows scientists to manipulate a mosquito’s genome in the lab and send it back into the wild. Introducing genes that sterilise the malaria-spreading female Anopheles mosquitoes could force that population into extinction, taking malaria down with it. But geneticists must also consider the mosquito’s ecological niche: The bug is part of a healthy diet for animals such as fish and birds.

ANSWERS FOR HEAD TRIP

WARRIORS AND LORDS, p. 67 question one: Green is a warrior, red is a lord. This remains true if the one in green is a warrior or a lord. But, if green were a lord, they’d be lying. So, green can only be a warrior, making red a lord. question two: Which direction would the other person tell me to go to get me in the right place? If the person you ask is a warrior, the other must be a lord. The lord would lie and say the opposite of where to go. If the person were a lord, the other would be a warrior bearing the truth—but the lord would lie about what the warrior says. In either case, you would get the opposite of the correct direction.…

One Last Outing for the Moller Skycar

OF ALL THE FUTURE predictions that Popular Science has made, surely the least accurate has been for the ›lying car. We’ve featured ›lying cars on our cover more times than our interns were prepared to count, and yet such technology still remains out of reach of regular people. This cover feature on the infamous Moller Skycar from March 2000 was by no means the ›irst ›lying car we ever put on the cover. Indeed, the second article from this old issue (see page 76) references an earlier ›lying car story, from 1952!

One Last Outing for the Moller Skycar

WHEN THE BUBBLE canopy is lowered, enveloping you in the M400 Skycar’s cockpit, you become lost in its possibilities. The single stick that controls pitch, yaw, and direction falls to hand. Eight ignition switches and starter buttons are at the ready. The hood slopes away, braced by two rounded ducts housing four of the eight rotary engines that lift you with 720 horsepower, then launch you into the sky at more than a mile a minute. The M400 is a flying car that promises to let you take off from your backyard—assuming you have a pretty big backyard—and fly to your destination at 350 mph, ignoring, if not gazing condescendingly upon, land-bound commuters stuck in traf›ic below. The brainchild of 63-year-old Paul Moller, the M400 lifts off on the thrust…

That The Plane Drove

A prolific inventor's greatest creation may soon fly again. Here, appearances are deceiving. The Airphibian is a “road-able aircraft”—it could doff its wings, propeller, and tail to take to the highway. Like most of the artifacts, memorabilia, and inventions packed chock-a-block throughout the 90-year-old Fulton’s woodsy Newton, Connecticut, home, the aircraft is an entry page onto a life spent defying distance and conventionality. In the heady aftermath of World War II, when American ingenuity seemed limitless, the notion of a flying car in every garage was the next technological wonder around the bend. Among those who came closest to making this dream reality was Robert Edison Fulton Jr. Today the Airphibian, nearly abandoned after flying thousands or two above the water. Little by little, he learned to take off, land,…

YOU CAN READ ABOUT THE MAN Behind the Airphibian in our March 2000 issue (reproduced on the previous spread) but this ›inal Retro Invention will be about the machine itself. And what a machine. The main problem with most flying car concepts is they approach the problem from the wrong direction. “Let’s make a car that people can fly!” say their inventors, whereupon begins years of futile thrashing away at concepts and prototypes that never work properly, because building a plane that as small as a car and - more importantly - is easy to fly, is almost impossible. The Airphibian, on the other hand, approaches the problem from the opposite direction. “Let’s make a plane that people can drive on the road!” its inventor, Robert Edison Fulton Jr said.…

THE DREAM LINGERS ON

Despite the endless failures or at best, massive disappointments of every ›lying car or ›lying-car-like product ever, brave and insane engineer-entrepreneurs keep banging away at this idea. The latest trend is for the ›ixed-wing ›lying cars (and “roadable” planes) to ditch their old-school propellers and aerodynamic surfaces, and turn into gigantic drones, basically. Multi-rotor seems to be the idea now, which as far as we’re concerned just proves what we’ve been saying all along: the ›lying car was invented decades ago, and we ’ve had ›lying cars since before World War 2. They’re called “helicopters”.…
