Last October, near Karlsruhe, Germany, Thomas Senkel completed the first manned flight of an electric multicopter, flying it 10 feet off the ground for 90 seconds. Senkel, a physicist and paraglider pilot who helped found the company E-volo to build the craft, invented it after seeing a YouTube video of a German hobbyist's remote-controlled hexacopter in action.

Multicopters are more stable and easier to control than helicopters. They're also potentially safer: The craft can land even after four of its 16 rotors, each of which has its own battery-powered motor, have failed. Multicopters could also be fitted with a parachute (which would be caught in the overhead rotor on a helicopter). E-volo says it will build a two-seat multicopter by the spring and begin selling the craft for recreational purposes next year.

A robotic hand made entirely of Legos is one of the most realistic robo-hands we have seen, matching the entire range of motion of a real one. It moves pretty slowly, but that's OK - slow and steady wins the race, and pours the drink without splashing.

Builder Max Shepherd used Lego motors and pneumatics to move the arm, which he says can only lift a couple of pounds. The goal was to mimic the full range of motion of a human hand, not to lift tons of weight. It's an impressive show of what can be done with some mad Lego skills.

The softest grippy hands we have seen don't look human at all, so this is quite a feat. Watch the fingers curl softly around a water bottle or other object.

The All-Electric BMW Active E

BMW Active E BMW
You'll need to rethink the way you drive, literally

The ActiveE is BMW's all-new electric vehicle, designed as a ‘beta' version of the forthcoming i3. Based on the swell little 1 Series Coupe, the Active E uses similar drive train and battery technologies as the i3, but in a less future-luxe package.

BMW says the Active E represents the second part of their three-phase electric vehicle development plan, which will culminate in the series production of the BMW i3 electric vehicle sometime in 2013.

What's New?

BMW took what they learned from the MINI E and created, for the first time, what feels like a fully realized electric car. BMW developed everything in the car - the energy storage module, its wiring, the electric motor, the power electronics and the transmission. The power plant - a 170-horsepower, 184 pound-feet-of-torque, 125-kW electric motor - is shoehorned into the engine bay and is powered by a 32-kilowatt-hour lithium-ion battery pack. While BMW designed the battery pack too, the cells are made by SB LiMotive, a partnership between Samsung and Bosch.

Because lithium-ion batteries are so temperature-sensitive, BMW developed a new management system with a ‘Smart Function' that warms the battery pack remotely, resulting in less loss. Also new on the Active E is a ‘Gliding" mode, which makes for a less obtrusive drive. That said, it takes some time to learn to drive an electric car. Whereas in a gas-powered car, you slow down by using the brakes, in the Active E, you can slow down using the accelerator pedal, via brake energy regeneration. To wit: when you lift off the accelerator, the electric motor becomes, as BMW says ‘a generator that feeds the electricity gained from kinetic energy back into the vehicle battery," resulting in torque braking. BMW says you can spend 75 percent of city driving never using the brake pedal. On our 20-mile loop in the car that proved true.

What's Good

Unlike the much-maligned drive on the MINI E, the drive on the Active E is pretty damn good, electric vehicle or not. The regenerative braking is a lot less active than on the MINI E, which was close to the point of being obtrusive. While BMW told us the MINI E customers liked the regenerative braking, the engineers went back and did a major re-think, resulting in the new gliding mode. BMW calls this ‘a distinctive intermediate position of the accelerator pedal' which allows the vehicle to glide without using any energy.

What's Bad

It's somewhat hard to fault the short range of an electric car, but, while we really enjoyed the Active E, it would be hard to present it as an option for a one-car household. With a range of 100 miles or so, we'd still live in fear of running out of juice at an inopportune time or if your short commute turns into a long one due to traffic.

Also, you'll need to rethink the way you drive. Due to the aforementioned regenerative braking and glide mode, you'll need to learn to drive with just your left foot -- and think of the ‘gas' pedal as both an accelerator and a brake. Whoa!

The Price

The ActiveE is available with a 24-month lease in limited markets - Los Angeles, San Diego, San Francisco, Sacramento, New York, Boston and Hartford. For $499 per month, with $2,250 down, you too can drive off in one of the 700 electric BMWs allocated for the US. Which is about the same price you'll pay for a well-equipped gas-powered 1 Series. Don't forget, you'll also need to pay for an in-home electric charging station, which runs about 2500 dollars.

The Verdict

BMW presents a pretty compelling proposition here. But while we admire and respect what BMW has accomplished with the Active E and feel they'll have no problem leasing all 700 that are coming to the states, the Active E is starting to make us pine for the third stage of the BMW group electrification, the iBrand vehicles. That said, if you want an electric car now that ups the style factor from the Nissan Leaf, the Active E is the car for you.

Free To a Good Home: One Space Telescope, Still In Orbit

Galaxy Evolution Explorer NASA

In an unusual move, our cash-strapped space agency is contemplating the donation of one of its still-functional space telescopes. The Galaxy Evolution Explorer mission is out of money, but the observatory still works just fine, so NASA might give it away - if Caltech wants it.

Probably not much would change for the daily life of the 9-year-old space telescope, which has been beaming back pictures of galaxies for way longer than it was designed to last. The California Institute of Technology already leads the mission and takes care of science operations and data analysis. But NASA owns and built the telescope, which was designed to have a life-cycle cost of $150 million. This donation would really be a legal thing, transferring ownership of the telescope as well as operation. Caltech would not give NASA any money, according to NASA.

GALEX, as it's known to its friends, was placed into standby mode last week as officials prepared to shut it down permanently. It was initially recommended for decommissioning next year, but NASA acted faster to save money. It's not clear how much this saves, however. Spaceflight Now reported the transfer plans on Friday.

Since its 2003 launch, GALEX has discovered plenty of neat things, including a gigantic comet-like tail behind a speeding star; "teenager" galaxies, which help to explain how galaxies evolve; and confirmation ofthe existence of dark energy.

Transferring ownership of a space telescope is a bit more complicated than re-homing a dog, but there is a provision in U.S. law that provides for such a deed. The Stevenson-Wydler Technology Innovation Act allows the transfer of government-owned research equipment to nonprofits or educational institutions, Spaceflight Now says. NASA has donated retired equipment under this act, but never a functioning spaceborne asset. Commercial satellites change hands frequently, but that's a different story.

Caltech officials are discussing what to do, and will notify NASA by March 31, Spaceflight Now reports. Then GALEX will either get new owners or shut down for good.

A Tribute to the Fifty: A Nine-Story Forging Press That Can Benchpress a Battleship

At PopSci we've always got our eyes to the future, but every now and then we have to pause and take a look back at the giants on whose shoulders we stand--especially when those giants stand nine stories tall, weigh 16 million pounds, and exert 50,000 tons of pressure. The Fifty--pictured above--is one of ten machines built in the 1950s as part of a U.S. government initiative called the Heavy Press Program, and it is to the HPP that we owe many of the large-scale trappings of modern life, including the Jet Age.

Described in detail over at The Atlantic (and further, with additional pics, at BoingBoing), the HPP followed on the heels of World War II and the allied discovery of the industrial processes that put Nazi jets into the air during an era when the best the Americans could muster were the effective yet technologically inferior propellor-driven aircraft like the B-29s, B-25s, P-51 Mustangs and the like that became icons of American wartime air power. After the war, the Soviets managed to get all the good German industrial hardware. So America built the Fifty.

These machines could press huge pieces of titanium into the super-strong, single-piece bulkheads necessary to construct the sturdy airframes needed to endure the stresses of supersonic flight. And they still can--the presses still operate to this day. The HPP spawned the American Jet Age, Tim Heffernan writes over at BoingBoing, and helped enable what would later become known as the military industrial complex. Say what you will about all that, but there's no arguing this: these presses are truly magnificent machines. More pics and background over at BoingBoing.

Today's NASA Budget: 'Irrational' Cuts to Planetary Science Mean Mars Missions Get the Axe

The James Webb Space Telescope NASA

NASA's new budget is slated to land on Capitol Hill today, and it's not quite what the space agency was hoping for. President Obama is asking Congress for $17.7 billion for NASA in 2013, funding it at its lowest level in four years and a full billion dollars less than the President mapped out for the agency in the five-year budget he sent Congress last year. Perhaps hardest hit: future Mars missions. The planetary science division will lose $300 million (down to $1.2 billion, or a 20 percent cut), and Mars exploration will take the brunt of that reduction.

Two scientists already briefed on the 2013 budget have said that two joint NASA/ESA missions to explore Mars in 2016 and 2018 are getting the axe, saving NASA $1.4 billion but robbing NASA scientists of at least two more opportunities to put equipment down on the red planet.

Edward Weiler, NASA's former associate administrator for science, tells PNJ: "To me, it's totally irrational and unjustified. We are the only country on this planet that has the demonstrated ability to land on another planet, namely Mars. It is a national prestige issue."

Why the cuts to planetary science? One major reason is Hubble's successor, the James Webb Space Telescope, which is now running more than twice over budget. The $3.5 billion telescope turned $8 billion telescope has already been considered for scuttling before being saved by pledges to cut corners elsewhere. "Irrational" or not, NASA has made its decision: in the decade to come, we're (hopefully) going to see a huge bump in our deep space science capabilities via JWST, but it's going to come at the expense of planetary science.

NASA will lay out the whole budget publicly in a televised briefing at 2 p.m. EST.

Frozen Fruit Flies Come Back to Life

Feeding flies a "cryoprotectant" can save them from the cold

A larval fruit fly is hatched in the year 2011 and frozen while still pupating, half its body water solidified in frigid temperatures. After spending many generations in a state of suspended animation, the wee Drosophila melanogaster awakens and is allowed to grow up. One day, it wonders if it will ever be able to mate - but should it bring new larvae into this dystopian future?

As it turns out, the fly can successfully mate after all, and its offspring are perfectly healthy new larvae. Too bad for the fly, it dies in the lab so scientists can find out exactly how it survived this cryopreservation.

Vladimír Koštál and fellow researchers in the Czech Republic did this very experiment and they say fruit flies can survive being frozen at 23 degrees F, so long as they are fed a special pre-freeze diet containing an amino acid from their Arctic cousins.

Freeze tolerance is thought to be a highly complicated process in animals - only a few insects can do it at all, while the accumulation of ice crystals in most vertebrates' bodies is either very harmful or fatal. Koštál and colleagues wanted to find out how complex it would be to help D. melanogaster, one of the most important model organisms in modern biology, survive freezing temperatures. Pretty easy, actually, as long as they were fed a cocktail of cryopreservative before entering the big chill.

An Arctic fruit fly relative called Chymomyza costata can survive being submerged in liquid nitrogen - that's -320 degrees F - and in previous research, Koštál et. al figured out they do this by accumulating an amino acid called L-proline in their bodies. In this new study, the Czech researchers fed fruit fly larvae a diet containing L-proline and glycerol, another cryoprotectant, and cooled them down. Treated larvae were able to survive after half their body water froze, which happened at 23˚ F (-5˚C). The flies were frozen for 75 minutes before being slowly warmed.

"Upon melting, these larvae were able to continue development, metamorphosed into adults, and produced viable offspring," the researchers say.

Other researchers have been trying to make freezable fruit flies to better understand the genes underlying susceptibility to cold. Figuring out how organisms flourish in cold could help researchers understand how humans could, too - not necessarily to cryogenically preserve us, though that would be awesome, but to help organs survive on ice for longer periods so they can be transplanted. This research could have implications along those same lines, but it could also just be a handy solution for biologists working with flies - their unique genetic lines could be preserved in a deep chill, instead of requiring large and costly gene pools of live flies.

The paper was published in the Proceedings of the National Academy of Sciences.

How to Pump Half a Million Gallons of Fuel From a Listing Cruise Liner

And just how much fuel is that?

It's been nearly a full month since the Costa Concordia ran aground just off the Tuscan island of Giglio, and after two weeks of delays salvage workers yesterday began pumping operations aimed at recovering most of the half million gallons of fuel aboard the badly listing Italian cruise liner. Roughly 84 percent of that fuel is stuck in 15 large tanks, and pumping that volume out of the ship will likely take another month--and that's with the pumps running around the clock.

Pumping fuel from a capsized and largely unstable vessel the size of the Costa Concordia isn't going to be a simple chore. First, valves must be fixed to the tops and bottoms of each of the tanks beforehand--much of this preparation has been underway for weeks--and hoses attached to each. Then, the fuel must be heated to reduce its viscosity and get it to flow easier. Fuel then goes out via the top valve, and seawater is piped in the bottom to fill the vacuum left by the exiting fuel.

That's only half the battle. From there, salvage workers have to figure out how to deal with 500,000 gallons of potentially hazardous petroleum fuel.

500,000 gallons of diesel fuel. Just how much is that?

• 11,905 barrels full.

• About 72 standard tanker cars. • 10,000 bathtubs of diesel.

• 32,258 beer kegs full.

• An Olympic-sized pool holds 660,000 US gallons, so just 76 percent of that. • A volume equivalent to the blood of 380,000 average adult humans.

• Or the capacity of a 50-foot-diameter globe, like this one:
At $4.16 per gallon today in New York, that's a bit over $2 million worth of fuel. With that, if your diesel car gets 20 miles per gallon, you could drive around the Earth 400 times.


Robotics Kit Makes Building Robots as Easy as Stacking Blocks

Modular Robotics Cubelets KT06 Kit Claire Benoist
Create robots from square puzzle pieces

Building and programming robots is no small feat. Just to get a robot to perform a simple action-say, turning when someone claps-can require hours of coding. Cubelets make robot creation as simple as stacking blocks.

Each 1.6-inch cube contains an eight-megahertz processor preprogrammed to execute one function. The six-block starter kit includes a rechargeable battery brick, as well as cubes that roll on rubber wheels, display an LED at varying intensities, and detect changes in lighting. Users configure the blocks however they choose, and the arrangement determines how the finished robot acts. (Magnets hold the blocks together, allowing copper connectors to transmit data between cubes.) The kit can make about 30 different robots; attaching the battery block to wheeled and light-sensitive blocks, for example, produces a robot that walks when the lights turn on.

Users can also buy individual Cubelets that react to changes in temperature, chirp, spin, and more. Later this year, the manufacturer plans to release a Cubelet containing a Bluetooth chip. Through a computer or smartphone browser, tinkerers will be able to reprogram the blocks by accessing their code and replacing commands, such as cues to "go" or "beep," for an instant behavioral adjustment.

Voltage: 3.5 volts
Processor Speed: 8 megahertz per block
Battery Life: 2-6 hours
Price: $150 per set of 6, plus $25 (est.) for each additional cube

In Midst of Budget Woes, NASA Contemplates a Manned Waypoint In Orbit Near the Moon

$

The NASA budget that went to Capitol Hill yesterday dashed any plans to initiate new Mars exploration missions in the next few years, but amid the belt-tightening SPACE reports that NASA is exploring another idea that, while much closer to home, is still quite ambitious--the building of a manned waypoint (read: space station) at the Lagrangian point EML-2 on the far side of the moon. This international space station (but we'll have to think of a better name) would serve as a jumping off place for new science missions as well as a gateway to other destinations like asteroids, Martian moons, and--eventually--Mars.

NASA, its Mars ambitions on hold for now, is viewing such a waypoint as a near-term exploration asset with the capacity to deliver new science and technologies within the decade. It would incorporate NASA's core next-gen capabilities--the planned heavy lift rocket known as the Space Launch System (SLS) and the Orion Multi-Purpose Crew Vehicle--as well as technologies contributed by international partners.

And in the near-term, it could put humans further out into space than they've ever been--the kind of superlative mission the agency as lacked since the glory days of the Apollo Program.

According to a recent memo, NASA is fielding a team charged with developing a plan for exploring Earth-moon libration point 2 (Earth-moon libration point is equivalent to a Lagrange point, but specific to the Earth and moon), a point in space where the pull of two bodies roughly balance out, making it possible to more or less "park" a spacecraft there.

From EML-2, on the lunar far side, humans aboard a station could direct telerobotics on the side of our satellite that has been rarely studied (new lunar science!) while also conducting research into long-term deep space habitaiton (new human spaceflight science!) while giving NASA's next-generation manned space vehicles a destination (a new place to go!).

The idea, of course, being to build on the station. Start with some lunar science and some new deep space science enabled by being in the "quiet zone" on the far side of the moon. And after learning a bit about the effects of habitation so far out in space, use the waypoint as both a technology test bed and eventual enabler for exploration further and further into space.

Of course, this all sounds really, really expensive. Which brings us back to NASA's core problem this morning--a lack of funds for big flagship projects. We're ducking out on commitments to the ESA and cutting costs elsewhere this week. But talk is cheap enough. A group of ISS partners is meeting in Paris this week and will likely talk through the idea. The study is due back to NASA by March 30.

Machine Can Tell If Plants' Genes Are Modified By Watching Them Grow

Germinating Seedlings Phytomorph

Watching a plant grow and develop roots can be as tedious as ... watching a plant grow. But seeing plant development as it unfolds can expose just what happens to a genetically modified organism, and how certain gene expressions can make plants do certain things. Robotic cameras and machine-vision algorithms are making the process easier.

Plant physiologist Edgar Spalding at the University of Wisconsin-Madison creates time-lapse movies of plant root growth in action. A 2,300-pound, 6-foot-high robotic camera rig snaps pictures every 30 seconds, capturing the curling, twisting motion of germinating seeds putting out new roots. The National Science Foundation, which funds Spalding's lab, paid a visit and got a tour.

Genetically modifying a seed is a complex process on its own, but plant biologists also need to study the physical changes, comparing how genetically modified plants grow in relation to their wild-type brethren. This can take quite some time, so Spalding's lab focuses on building high-throughput data analysis tools, including the camera and specialized algorithms.

Like other plant research labs, the Phytomorph lab is an impressively high-tech operation, with the research subject lending a greenhouse-like casual air. Tiny plants germinate and rotate their root systems in petri dishes inside a Plexiglas wall that resembles a giant Connect Four game. Each plant grows under white LEDs, and infrared LEDs are used to illuminate the CCD imager on the robotic camera.

Computer vision algorithms study the camera's time-lapse videos and measure the sizes of seeds, plants' cellular growth rates, the angle and curvature of the roots, and more.

The main goal is to study how genes function, according to the NSF. The Phytomorph program has led to some new insights about how plant roots grow, including how they grow facing down, growing with gravity. All of this could be useful in pinpointing genes that botanists and plant biotechnologists would want to exploit, creating plants with tougher roots, or roots that could more easily seek out water and nutrients.

"It lays the foundation for discoveries that will help improve plants for human purposes," Spalding told the NSF.

The Boy Who Played With Fusion

Standout Taylor Wilson moved to suburban Reno with his parents, Kenneth and Tiffany, and his brother Joey to attend Davidson Academy, a school for gifted students. Bryce Duffy
Taylor Wilson always dreamed of creating a star. Now he's become one

"Propulsion," the nine-year-old says as he leads his dad through the gates of the U.S. Space and Rocket Center in Huntsville, Alabama. "I just want to see the propulsion stuff."

A young woman guides their group toward a full-scale replica of the massive Saturn V rocket that brought America to the moon. As they duck under the exhaust nozzles, Kenneth Wilson glances at his awestruck boy and feels his burden beginning to lighten. For a few minutes, at least, someone else will feed his son's boundless appetite for knowledge.

Then Taylor raises his hand, not with a question but an answer. He knows what makes this thing, the biggest rocket ever launched, go up. And he wants-no, he obviously needs-to tell everyone about it, about how speed relates to exhaust velocity and dynamic mass, about payload ratios, about the pros and cons of liquid versus solid fuel. The tour guide takes a step back, yielding the floor to this slender kid with a deep-Arkansas drawl, pouring out a torrent of Ph.D.-level concepts as if there might not be enough seconds in the day to blurt it all out. The other adults take a step back too, perhaps jolted off balance by the incongruities of age and audacity, intelligence and exuberance.

As the guide runs off to fetch the center's director-You gotta see this kid!-Kenneth feels the weight coming down on him again. What he doesn't understand just yet is that he will come to look back on these days as the uncomplicated ones, when his scary-smart son was into simple things, like rocket science.

This is before Taylor would transform the family's garage into a mysterious, glow-in-the-dark cache of rocks and metals and liquids with unimaginable powers. Before he would conceive, in a series of unlikely epiphanies, new ways to use neutrons to confront some of the biggest challenges of our time: cancer and nuclear terrorism. Before he would build a reactor that could hurl atoms together in a 500-million-degree plasma core-becoming, at 14, the youngest individual on Earth to achieve nuclear fusion.

* * *

When I meet Taylor Wilson, he is 16 and busy-far too busy, he says, to pursue a driver's license. And so he rides shotgun as his father zigzags the family's Land Rover up a steep trail in the Virginia Mountains north of Reno, Nevada, where they've come to prospect for uranium.

From the backseat, I can see Taylor's gull-like profile, his forehead plunging from under his sandy blond bangs and continuing, in an almost unwavering line, along his prominent nose. His thinness gives him a wraithlike appearance, but when he's lit up about something (as he is most waking moments), he does not seem frail. He has spent the past hour-the past few days, really-talking, analyzing, and breathlessly evangelizing about nuclear energy. We've gone back to the big bang and forward to mutually assured destruction and nuclear winter. In between are fission and fusion, Einstein and Oppenheimer, Chernobyl and Fukushima, matter and antimatter.

"Where does it come from?" Kenneth and his wife, Tiffany, have asked themselves many times. Kenneth is a Coca-Cola bottler, a skier, an ex-football player. Tiffany is a yoga instructor. "Neither of us knows a dang thing about science," Kenneth says.

" Looking up, the neighbors watched as a small mushroom cloud rose, unsettlingly, over the Wilsons' yard."Almost from the beginning, it was clear that the older of the Wilsons' two sons would be a difficult child to keep on the ground. It started with his first, and most pedestrian, interest: construction. As a toddler in Texarkana, the family's hometown, Taylor wanted nothing to do with toys. He played with real traffic cones, real barricades. At age four, he donned a fluorescent orange vest and hard hat and stood in front of the house, directing traffic. For his fifth birthday, he said, he wanted a crane. But when his parents brought him to a toy store, the boy saw it as an act of provocation. "No," he yelled, stomping his foot. "I want a real one."

This is about the time any other father might have put his own foot down. But Kenneth called a friend who owns a construction company, and on Taylor's birthday a six-ton crane pulled up to the party. The kids sat on the operator's lap and took turns at the controls, guiding the boom as it swung above the rooftops on Northern Hills Drive.

To the assembled parents, dressed in hard hats, the Wilsons' parenting style must have appeared curiously indulgent. In a few years, as Taylor began to get into some supremely dangerous stuff, it would seem perilously laissez-faire. But their approach to child rearing is, in fact, uncommonly intentional. "We want to help our children figure out who they are," Kenneth says, "and then do everything we can to help them nurture that."

At 10, Taylor hung a periodic table of the elements in his room. Within a week he memorized all the atomic numbers, masses and melting points. At the family's Thanksgiving gathering, the boy appeared wearing a monogrammed lab coat and armed with a handful of medical lancets. He announced that he'd be drawing blood from everyone, for "comparative genetic experiments" in the laboratory he had set up in his maternal grandmother's garage. Each member of the extended family duly offered a finger to be pricked.

The next summer, Taylor invited everyone out to the backyard, where he dramatically held up a pill bottle packed with a mixture of sugar and stump remover (potassium nitrate) that he'd discovered in the garage. He set the bottle down and, with a showman's flourish, ignited the fuse that poked out of the top. What happened next was not the firecracker's bang
everyone expected, but a thunderous blast that brought panicked neighbors running from their houses. Looking up, they watched as a small mushroom cloud rose, unsettlingly, over the Wilsons' yard.

For his 11th birthday, Taylor's grandmother took him to Books-A-Million, where he picked out The Radioactive Boy Scout, by Ken Silverstein. The book told the disquieting tale of David Hahn, a Michigan teenager who, in the mid-1990s, attempted to build a breeder reactor in a backyard shed. Taylor was so excited by the book that he read much of it aloud: the boy raiding smoke detectors for radioactive americium . . . the cobbled-together reactor . . . the Superfund team in hazmat suits hauling away the family's contaminated belongings. Kenneth and Tiffany heard Hahn's story as a cautionary tale. But Taylor, who had recently taken a particular interest in the bottom two rows of the periodic table-the highly radioactive elements-read it as a challenge. "Know what?" he said. "The things that kid was trying to do, I'm pretty sure I can actually do them."

A rational society would know what to do with a kid like Taylor Wilson, especially now that America's technical leadership is slipping and scientific talent increasingly has to be imported. But by the time Taylor was 12, both he and his brother, Joey, who is three years younger and gifted in mathematics, had moved far beyond their school's (and parents') ability to meaningfully teach them. Both boys were spending most of their school days on autopilot, their minds wandering away from course work they'd long outgrown./>

David Hahn had been bored too-and, like Taylor, smart enough to be dangerous. But here is where the two stories begin to diverge. When Hahn's parents forbade his atomic endeavors, the angry teenager pressed on in secret. But Kenneth and Tiffany resisted their impulse to steer Taylor toward more benign pursuits. That can't be easy when a child with a demonstrated talent and fondness for blowing things up proposes to dabble in nukes.

Kenneth and Tiffany agreed to let Taylor assemble a "survey of everyday radioactive materials" for his school's science fair. Kenneth borrowed a Geiger counter from a friend at Texarkana's emergency-management agency. Over the next few weekends, he and Tiffany shuttled Taylor around to nearby antique stores, where he pointed the clicking detector at old
radium-dial alarm clocks, thorium lantern mantles and uranium-glazed Fiesta plates. Taylor spent his allowance money on a radioactive dining set.

Drawn in by what he calls "the surprise properties" of radioactive materials, he wanted to know more. How can a speck of metal the size of a grain of salt put out such tremendous amounts of energy? Why do certain rocks expose film? Why does one isotope decay away in a millionth of a second while another has a half-life of two million years?

As Taylor began to wrap his head around the mind-blowing mysteries at the base of all matter, he could see that atoms, so small but potentially so powerful, offered a lifetime's worth of secrets to unlock. Whereas Hahn's resources had been limited, Taylor found that there was almost no end to the information he could find on the Internet, or to the oddities that he could purchase and store in the garage.

On top of tables crowded with chemicals and microscopes and germicidal black lights, an expanding array of nuclear fuel pellets, chunks of uranium and "pigs" (lead-lined containers) began to appear. When his parents pressed him about safety, Taylor responded in the convoluted jargon of inverse-square laws and distance intensities, time doses and roentgen submultiples. With his newfound command of these concepts, he assured them, he could master the furtive energy sneaking away from those rocks and metals and liquids-a strange and ever-multiplying cache that literally cast a glow into the corners of the garage.

Kenneth asked a nuclear-pharmacist friend to come over to check on Taylor's safety practices. As far as he could tell, the friend said, the boy was getting it right. But he warned that radiation works in quick and complex ways. By the time Taylor learned from a mistake, it might be too late.

Lead pigs and glazed plates were only the beginning. Soon Taylor was getting into more esoteric "naughties"-radium quack cures, depleted uranium, radio-luminescent materials-and collecting mysterious machines, such as the mass spectrometer given to him by a former astronaut in Houston. As visions of Chernobyl haunted his parents, Taylor tried to reassure them. "I'm the responsible radioactive boy scout," he told them. "I know what I'm doing."

One afternoon, Tiffany ducked her head out of the door to the garage and spotted Taylor, in his canary yellow nuclear-technician's coveralls, watching a pool of liquid spreading across the concrete floor. "Tay, it's time for supper."
"I think I'm going to have to clean this up first."
"That's not the stuff you said would kill us if it broke open, is it?"
"I don't think so," he said. "Not instantly."

* * *

That summer, Kenneth's daughter from a previous marriage, Ashlee, then a college student, came to live with the Wilsons. "The explosions in the backyard were getting to be a bit much," she told me, shortly before my own visit to the family's home. "I could see everyone getting frustrated. They'd say something and Taylor would argue back, and his argument would be legitimate. He knows how to out-think you. I was saying, ‘You guys need to be parents. He's ruling the roost.' "

"What she didn't understand," Kenneth says, "is that we didn't have a choice. Taylor doesn't understand the meaning of ‘can't.' "

"And when he does," Tiffany adds, "he doesn't listen."

"Looking back, I can see that," Ashlee concedes. "I mean, you can tell Taylor that the world doesn't revolve around him. But he doesn't really get that. He's not being selfish, it's just that there's so much going on in his head."

Tiffany, for her part, could have done with less drama. She had just lost her sister, her only sibling. And her mother's cancer had recently come out of remission. "Those were some tough times," Taylor tells me one day, as he uses his mom's gardening trowel to mix up a batch of yellowcake (the partially processed uranium that's the stuff of WMD infamy) in a five-gallon bucket. "But as bad as it was with Grandma dying and all, that urine sure was something."

Taylor looks sheepish. He knows this is weird. "After her PET scan she let me have a sample. It was so hot I had to keep it in a lead pig.

"The other thing is . . ." He pauses, unsure whether to continue but, being Taylor, unable to stop himself. "She had lung cancer, and she'd cough up little bits of tumor for me to dissect. Some people might think that's gross, but I found it scientifically very interesting."

What no one understood, at least not at first, was that as his grandmother was withering, Taylor was growing, moving beyond mere self-centeredness. The world that he saw revolving around him, the boy was coming to believe, was one that he could actually change.

The problem, as he saw it, is that isotopes for diagnosing and treating cancer are extremely short-lived. They need to be, so they can get in and kill the targeted tumors and then decay away quickly, sparing healthy cells. Delivering them safely and on time requires expensive handling-including, often, delivery by private jet. But what if there were a way to make those medical isotopes at or near the patients? How many more people could they reach, and how much earlier could they reach them? How many more people like his grandmother could be saved?

"He told me he wanted to build the reactor in his garage, and I thought, ‘Oh my lord, we can't let him do that.' "As Taylor stirred the toxic urine sample, holding the clicking Geiger counter over it, inspiration took hold. He peered into the swirling yellow center, and the answer shone up at him, bright as the sun. In fact, it was the sun-or, more precisely, nuclear fusion, the process (defined by Einstein as E=mc2) that powers the sun. By harnessing fusion-the moment when atomic nuclei collide and fuse together, releasing energy in the process-Taylor could produce the high-energy neutrons he would need to irradiate materials for medical isotopes. Instead of creating those isotopes in multimillion-dollar cyclotrons and then rushing them to patients, what if he could build a fusion reactor small enough, cheap enough and safe enough to produce isotopes as needed, in every hospital in the world?

At that point, only 10 individuals had managed to build working fusion reactors. Taylor contacted one of them, Carl Willis, then a 26-year-old Ph.D. candidate living in Albuquerque, and the two hit it off. But Willis, like the other successful fusioneers, had an advanced degree and access to a high-tech lab and precision equipment. How could a middle-school kid living on the Texas/Arkansas border ever hope to make his own star?


When Taylor was 13, just after his grandmother's doctor had given her a few weeks to live, Ashlee sent Tiffany and Kenneth an article about a new school in Reno. The Davidson Academy is a subsidized public school for the nation's smartest and most motivated students, those who score in the top 99.9th percentile on standardized tests. The school, which allows students to pursue advanced research at the adjacent University of Nevada-Reno, was founded in 2006 by software entrepreneurs Janice and Robert Davidson. Since then, the Davidsons have championed the idea that the most underserved students in the country are those at the top./>

On the family's first trip to Reno, even before Taylor and Joey were accepted to the academy, Taylor made an appointment with Friedwardt Winterberg, a celebrated physicist at the University of Nevada who had studied under the Nobel Prize-winning quantum theorist Werner Heisenberg. When Taylor told Winterberg that he wanted to build a fusion reactor, also called a fusor, the notoriously cranky professor erupted: "You're 13 years old! And you want to play with tens of thousands of electron volts and deadly x-rays?" Such a project would be far too technically challenging and hazardous, Winterberg insisted, even for most doctoral candidates. "First you must master calculus, the language of science," he boomed. "After that," Tiffany said, "we didn't think it would go anywhere. Kenneth and I were a bit relieved."

But Taylor still hadn't learned the word "can't." In the fall, when he began at Davidson, he found the two advocates he needed, one in the office right next door to Winterberg's. "He had a depth of understanding I'd never seen in someone that young," says atomic physicist Ronald Phaneuf. "But he was telling me he wanted to build the reactor in his garage, and I'm thinking, ‘Oh my lord, we can't let him do that.' But maybe we can help him try to do it here."

Phaneuf invited Taylor to sit in on his upper-division nuclear physics class and introduced him to technician Bill Brinsmead. Brinsmead, a Burning Man devotee who often rides a wheeled replica of the Little Boy bomb through the desert, was at first reluctant to get involved in this 13-year-old's project. But as he and Phaneuf showed Taylor around the department's equipment room, Brinsmead recalled his own boyhood, when he was bored and unchallenged and aching to build something really cool and difficult (like a laser, which he eventually did build) but dissuaded by most of the adults who might have helped.

Rummaging through storerooms crowded with a geeky abundance of electron microscopes and instrumentation modules, they came across a high-vacuum chamber made of thick-walled stainless steel, capable of withstanding extreme heat and negative pressure. "Think I could use that for my fusor?" Taylor asked Brinsmead. "I can't think of a more worthy cause," Brinsmead said.

* * *

Now it's Tiffany who drives, along a dirt road that wends across a vast, open mesa a few miles south of the runways shared by Albuquerque's airport and Kirkland Air Force Base. Taylor has convinced her to bring him to New Mexico to spend a week with Carl Willis, whom Taylor describes as "my best nuke friend." Cocking my ear toward the backseat, I catch snippets of Taylor and Willis's conversation.

"The idea is to make a gamma-ray laser from stimulated decay of dipositronium."

"I'm thinking about building a portable, beam-on-target neutron source."

"Need some deuterated polyethylene?"

Willis is now 30; tall and thin and much quieter than Taylor. When he's interested in something, his face opens up with a blend of amusement and curiosity. When he's uninterested, he slips into the far-off distractedness that's common among the super-smart. Taylor and Willis like to get together a few times a year for what they call "nuclear tourism"-they visit research facilities, prospect for uranium, or run experiments.

Earlier in the week, we prospected for uranium in the desert and shopped for secondhand laboratory equipment in Los Alamos. The next day, we wandered through Bayo Canyon, where Manhattan Project engineers set off some of the largest dirty bombs in history in the course of perfecting Fat Man, which leveled Nagasaki.

Today we're searching for remnants of a "broken arrow," military lingo for a lost nuclear weapon. While researching declassified military reports, Taylor discovered that a Mark 17 "Peacemaker" hydrogen bomb, which was designed to be 700 times as powerful as the bomb detonated over Hiroshima, was accidentally dropped onto this mesa in May 1957. For the U.S. military, it was an embarrassingly Strangelovian episode; the airman in the bomb bay narrowly avoided his own Slim Pickens moment when the bomb dropped from its gantry and smashed the B-36's doors open. Although its plutonium core hadn't been inserted, the bomb's "spark plug" of conventional explosives and radioactive material detonated on impact, creating a fireball and a massive crater. A grazing steer was the only reported casualty.

Tiffany parks the rented SUV among the mesquite, and we unload metal detectors and Geiger counters and fan out across the field. "This," says Tiffany, smiling as she follows her son across the scrubland, "is how we spend our vacations."

/>

Willis says that when Taylor first contacted him, he was struck by the 12-year-old's focus and forwardness-and by the fact that he couldn't plumb the depth of Taylor's knowledge with a few difficult technical questions. After checking with Kenneth, Willis sent Taylor some papers on fusion reactors. Then Taylor began acquiring pieces for his new machine.

Through his first year at Davidson, Taylor spent his afternoons in a corner of Phaneuf's lab that the professor had cleared out for him, designing the reactor, overcoming tricky technical issues, tracking down critical parts. Phaneuf helped him find a surplus high-voltage insulator at Lawrence Berkeley National Laboratory. Willis, then working at a company that builds particle accelerators, talked his boss into parting with an extremely expensive high-voltage power supply.

With Brinsmead and Phaneuf's help, Taylor stretched himself, applying knowledge from more than 20 technical fields, including nuclear and plasma physics, chemistry, radiation metrology and electrical engineering. Slowly he began to test-assemble the reactor, troubleshooting pesky vacuum leaks, electrical problems and an intermittent plasma field.

Shortly after his 14th birthday, Taylor and Brinsmead loaded deuterium fuel into the machine, brought up the power, and confirmed the presence of neutrons. With that, Taylor became the 32nd individual on the planet to achieve a nuclear-fusion reaction. Yet what would set Taylor apart from the others was not the machine itself but what he decided to do with it.

While still developing his medical isotope application, Taylor came across a report about how the thousands of shipping containers entering the country daily had become the nation's most vulnerable "soft belly," the easiest entry point for weapons of mass destruction. Lying in bed one night, he hit on an idea: Why not use a fusion reactor to produce weapons-sniffing neutrons that could scan the contents of containers as they passed through ports? Over the next few weeks, he devised a concept for a drive-through device that would use a small reactor to bombard passing containers with neutrons. If weapons were inside, the neutrons would force the atoms into fission, emitting gamma radiation (in the case of nuclear material) or nitrogen (in the case of conventional explosives). A detector, mounted opposite, would pick up the signature and alert the operator.

He entered the reactor, and the design for his bomb-sniffing application, into the Intel International Science and Engineering Fair. The Super Bowl of pre-college science events, the fair attracts 1,500 of the world's most switched-on kids from some 50 countries. When Intel CEO Paul Otellini heard the buzz that a 14-year-old had built a working nuclear-fusion reactor, he went straight for Taylor's exhibit. After a 20-minute conversation, Otellini was seen walking away, smiling and shaking his head in what looked like disbelief. Later, I would ask him what he was thinking. "All I could think was, ‘I am so glad that kid is on our side.' "

For the past three years, Taylor has dominated the international science fair, walking away with nine awards (including first place overall), overseas trips and more than $100,000 in prizes. After the Department of Homeland Security learned of Taylor's design, he traveled to Washington for a meeting with the DHS's Domestic Nuclear Detection Office, which invited Taylor to submit a grant proposal to develop the detector. Taylor also met with then-Under Secretary of Energy Kristina Johnson, who says the encounter left her "stunned."

"I would say someone like him comes along maybe once in a generation," Johnson says. "He's not just smart; he's cool and articulate. I think he may be the most amazing kid I've ever met."

And yet Taylor's story began much like David Hahn's, with a brilliant, high-flying child hatching a crazy plan to build a nuclear reactor. Why did one journey end with hazmat teams and an eventual arrest, while the other continues to produce an array of prizes, patents, television appearances, and offers from college recruiters?

The answer is, mostly, support. Hahn, determined to achieve something extraordinary but discouraged by the adults in his life, pressed on without guidance or oversight-and with nearly catastrophic results. Taylor, just as determined but socially gifted, managed to gather into his orbit people who could help him achieve his dreams: the physics professor; the older nuclear prodigy; the eccentric technician; the entrepreneur couple who, instead of retiring, founded a school to nurture genius kids. There were several more, but none so significant as Tiffany and Kenneth, the parents who overcame their reflexive-and undeniably sensible-inclinations to keep their Icarus-like son on the ground. Instead they gave him the wings he sought and encouraged him to fly up to the sun and beyond, high enough to capture a star of his own.

After about an hour of searching across the mesa, our detectors begin to beep. We find bits of charred white plastic and chunks of aluminum-one of which is slightly radioactive. They are remnants of the lost hydrogen bomb. I uncover a broken flange with screws still attached, and Taylor digs up a hunk of lead. "Got a nice shard here," Taylor yells, finding a gnarled piece of metal. He scans it with his detector. "Unfortunately, it's not radioactive."

"That's the kind I like," Tiffany says.

"We've got about 60 pounds of uranium, bomb fragments and radioactive shards. This thing would make a real good dirty bomb."Willis picks up a large chunk of the bomb's outer casing, still painted dull green, and calls Taylor over. "Wow, look at that warp profile!" Taylor says, easing his scintillation detector up to it. The instrument roars its approval. Willis, seeing Taylor ogling the treasure, presents it to him. Taylor is ecstatic. "It's a field of dreams!" he yells. "This place is loaded!"

Suddenly we're finding radioactive debris under the surface every five or six feet-even though the military claimed that the site was completely cleaned up. Taylor gets down on his hands and knees, digging, laughing, calling out his discoveries. Tiffany checks her watch. "Tay, we really gotta go or we'll miss our flight."

"I'm not even close to being done!" he says, still digging. "This is the best day of my life!" By the time we manage to get Taylor into the car, we're running seriously late. "Tay," Tiffany says, "what are we going to do with all this stuff?"

"For $50, you can check it on as excess baggage," Willis says. "You don't label it, nobody knows what it is, and it won't hurt anybody." A few minutes later, we're taping an all-too-flimsy box shut and loading it into the trunk. "Let's see, we've got about 60 pounds of uranium, bomb fragments and radioactive shards," Taylor says. "This thing would make a real good dirty bomb."

In truth, the radiation levels are low enough that, without prolonged close-range exposure, the cargo poses little danger. Still, we stifle the jokes as we pull up to curbside check-in. "Think it will get through security?" Tiffany asks Taylor.

"There are no radiation detectors in airports," Taylor says. "Except for one pilot project, and I can't tell you which airport that's at."

As the skycap weighs the box, I scan the "prohibited items" sign. You can't take paints, flammable materials or water on a commercial airplane. But sure enough, radioactive materials are not listed.

We land in Reno and make our way toward the baggage claim. "I hope that box held up," Taylor says, as we approach the carousel. "And if it didn't, I hope they give us back the radioactive goodies scattered all over the airplane." Soon the box appears, adorned with a bright strip of tape and a note inside explaining that the package has been opened and inspected by the TSA. "They had no idea," Taylor says, smiling, "what they were looking at."

* * *

Apart from the fingerprint scanners at the door, Davidson Academy looks a lot like a typical high school. It's only when the students open their mouths that you realize that this is an exceptional place, a sort of Hogwarts for brainiacs. As these math whizzes, musical prodigies and chess masters pass in the hallway, the banter flies in witty bursts. Inside humanities classes, discussions spin into intellectual duels.

Although everyone has some kind of advanced obsession, there's no question that Taylor is a celebrity at the school, where the lobby walls are hung with framed newspaper clippings of his accomplishments. Taylor and I visit with the principal, the school's founders and a few of Taylor's friends. Then, after his calculus class, we head over to the university's physics department, where we meet Phaneuf and Brinsmead.

Taylor's reactor, adorned with yellow radiation-warning signs, dominates the far corner of Phaneuf's lab. It looks elegant-a gleaming stainless-steel and glass chamber on top of a cylindrical trunk, connected to an array of sensors and feeder tubes. Peering through the small window into the reaction chamber, I can see the golf-ball-size grid of tungsten fingers that will cradle the plasma, the state of matter in which unbound electrons, ions and photons mix freely with atoms and molecules.

"OK, y'all stand back," Taylor says. We retreat behind a wall of leaden blocks as he shakes the hair out of his eyes and flips a switch. He turns a knob to bring the voltage up and adds in some gas. "This is exactly how me and Bill did it the first time," he says. "But now we've got it running even better."

Through a video monitor, I watch the tungsten wires beginning to glow, then brightening to a vivid orange. A blue cloud of plasma appears, rising and hovering, ghostlike, in the center of the reaction chamber. "When the wires disappear," Phaneuf says, "that's when you know you have a lethal radiation field."

I watch the monitor while Taylor concentrates on the controls and gauges, especially the neutron detector they've dubbed Snoopy. "I've got it up to 25,000 volts now," Taylor says. "I'm going to out-gas it a little and push it up."

Willis's power supply crackles. The reactor is entering "star mode." Rays of plasma dart between gaps in the now-invisible grid as deuterium atoms, accelerated by the tremendous voltages, begin to collide. Brinsmead keeps his eyes glued to the neutron detector. "We're getting neutrons," he shouts. "It's really jamming!"

Taylor cranks it up to 40,000 volts. "Whoa, look at Snoopy now!" Phaneuf says, grinning. Taylor nudges the power up to 50,000 volts, bringing the temperature of the plasma inside the core to an incomprehensible 580 million degrees-some 40 times as hot as the core of the sun. Brinsmead lets out a whoop as the neutron gauge tops out.

"Snoopy's pegged!" he yells, doing a little dance. On the video screen, purple sparks fly away from the plasma cloud, illuminating the wonder in the faces of Phaneuf and Brinsmead, who stand in a half-orbit around Taylor. In the glow of the boy's creation, the men suddenly look years younger.

Taylor keeps his thin fingers on the dial as the atoms collide and fuse and throw off their energy, and the men take a step back, shaking their heads and wearing ear-to-ear grins.

"There it is," Taylor says, his eyes locked on the machine. "The birth of a star."

NASA's Mars Budget Takes a Beating, Leaving Europe to Fly Joint Missions Solo

ExoMars: The Mars Rover That Likely Will Never Be ESA
The White House wants NASA to collaborate with international partners. But it doesn't want to pay

Of the panoply of dollar values and percentages that made headlines during yesterday's federal budget unveiling, there's one number that stands out that nonetheless received almost no mention yesterday: Five. That's the number of large-scale space missions, originally designed as joint NASA-ESA operations, that the U.S. has backed out of in the last 12 months. Bailing on its international partners is starting to become a disturbing trend at the world's premier space agency.

In the 2013 budget that the White House released Monday, NASA took its lumps like everyone else. The planetary science division, though, was hammered, losing 20 percent of its current budget and forcing it to abandon the ExoMars missions--two joint NASA-European Space Agency exploration missions to Mars slated for 2016 and 2018.

ExoMars joins the ranks of LISA, IXO, and EJSM, all currently stalled for lack of NASA funds. LISA, the Laser Interferometer Space Antenna, would've been the first dedicated space-based gravitational wave detector and--with constituent parts spaced 3 million miles apart--the largest single experiment in the known universe. IXO, the International X-Ray Observatory would've followed on the success of NASA's Chandra X-Ray Observatory and the ESA's XMM-Newton Observatory, mapping large scale structures in X-ray and studying black holes. Both LISA and IXO were listed among the Astro2019 Decadal Survey of space science priorities.

A third mission, the jointly backed Europa Jupiter System Mission (EJSM), would've launched at the end of the decade to explore Jupiter's moons. NASA has backed out of all three over the past year, citing budget constraints. In all three cases, the ESA is looking into the idea of going it alone, or collaborating with other partners like Russia and Japan to bring these missions to fruition.

It's difficult to decipher exactly what the message coming from the White House to NASA is.What's most mystifying here is not that NASA is backing out of the aforementioned missions--indeed if you can't afford it, you can't afford it--but how it got involved in them in the first place. And at issue is whether or not NASA wishes to be an integral part of these kinds of missions, or whether it would rather take a backseat.

Either choice is fine, based on NASA's priorities--I won't argue that NASA must be first and best at everything. But a choice does have to be made. Joint NASA/ESA missions like ExoMars are the direct result of the 2010 space policy put forth by the Obama administration--a policy that called for one thing above all else: international collaboration across the board. Why spend the redundant dollars in Europe and the U.S., the president's advisers argued, when we can collaborate on missions and get more bang for our collective bucks?

"If there's one really broad theme it is international cooperation, which is woven throughout the new policy and it's our sort of foundational emphasis for achieving all of our goals in space," said Barry Pavel, senior director for defense policy and strategy for the National Security Council, at the time.

All that is to say that missions like LISA, IXO, and ExoMars were directly in line with the space agenda being pushed at the White House just two years ago. It was a good message. Looking back from 2012, it's difficult to decipher exactly what the message coming from the White House to NASA is. To the scientists who have spent the last two years implementing this strategy of international collaboration, the new budget heaps inefficiency on top of incoherence. But to our biggest space ally in Europe, the message must be getting pretty clear at this point: NASA can't keep its agreements.

Missions like ExoMars and LISA don't exist in a void somewhere, penned on a whiteboard and otherwise disconnected from people and the machinery of government. Skin is already in the game. For the ESA's member states, that's estimated at something like 200 million euros, which will likely go up in smoke if the ESA can't find the money and political will to move forward alone (or with Russia, who doesn't bring the same technical expertise to the table as America would have) in time for an ESA council meeting in March. Surely there is some built-in economic cost to NASA as well, both in money and lost productivity, though at the time of this writing no number is being floated by the agency. This kind of waste isn't productive in an environment where the word "austerity" has come to define an era.

That's not to say that all is lost. NASA hasn't totally abandoned its friends at ESA by any means, and NASA chief Charles Bolden's staff is working with its ESA counterpart to pare down ExoMars to a single 2018 mission that would cost NASA a half a billion dollars less (reportedly with funds pulled from directorates beyond just planetary science, like human spaceflight and space technology).

But the fact remains that the message that the White House and Congress is sending NASA is as murky as ever, and that in turn is making NASA look pretty unreliable. Each time we leave Europe holding the bag it costs NASA prestige. Eventually, it could cost NASA a key partner.

Compound Reinvigorates Classic Antibiotics In Fight Against New Superbacteria

A new drug compound can recharge a class of antibiotics used to fight superbug bacteria, improving the antibiotics' effectiveness 16-fold. It's another volley on the part of humans in the ongoing battle between new drugs and bacterial resistance.

This new compound doesn't fight the bacteria itself - it just makes the antibacterial drugs more potent, and better able to fight the bacteria despite the bugs' resistance. The compound, developed at North Carolina State University, could help researchers fight an emerging problem with a tricky bacterial enzyme.

The enzyme is called New Delhi metallo-β-lactamase, or NDM-1, and it has been found in bacterial strains around the world since its isolation in 2008. It's particularly ugly because it makes bacteria able to resist a broad range of antibiotics - including the type that are typically used to fight antibiotic-resistant bacteria. It can resist the most powerful drugs that still work on drug-resistant bacteria, in other words. A superbug indeed. To make matters worse, it confers this ability on gram-negative bacteria, little bugs that are harder to treat - like E. coli and  K. pneumoniae. The Staph strain MRSA, the superbug we hear about most often, is a gram-positive bacteria.

Resistance-proof drugs, part of the carbapenem family, can kill most bacteria by preventing their cell walls from synthesizing properly. NDM-1 gives the bacteria a tool to break down those drugs and inactivate them. But this new compound thwarts that ability, making the carbapenem drugs better able to withstand the wily bacteria and fight infection. The compound is derived from a class of amino acids known as 2-aminoimidazoles. These amino acids can inhibit the growth of bacterial biofilms.

In previous research, NC State chemist Christian Melander found that the amino acid compounds could recharge existing antibiotics, and make them work better against gram-positive drug-resistant bacteria. They figured it might also work on the little guys, and it did. Melander and colleagues just published a paper in ACS Medicinal Chemistry Letters, explaining that a version of this amino acid compound pumped up the power of the antibiotics imipenem and meropenem 16-fold.

This is promising for future drug development, the researchers say - it could to our arsenal in the ongoing battle against microbe resistance.

World's Tiniest Chameleons Found in Madagascar

Smallest Lizard A juvenile Brookesia micra is barely bigger than a match head. Glaw et al/PLoS One

This little chameleon is one of four miniature lizards identified in Madagascar, adding to our growing list of amazingly teeny animals. The one on the match in this picture is a juvenile, but even the adults max out at 30 millimeters. They're the smallest lizards in the world, and some of the smallest vertebrates found to date.

The Lilliputian lizard is near the lower limits of size in vertebrate animals. Learning about how these creatures live can put some constraints on animal morphology - if your species has eyes, a backbone and a brain, there's likely a limit to how little you can get. A different group of field biologists just announced the world's smallest frog, and they claim it is the smallest vertebrate in the world, knocking a tiny Indonesian fish off the pedestal of puniness.

The chameleons are related to other Madagascan lizards, but DNA analysis showed they have enough genetic differences to count as distinct species, according to the researchers who found them, led by Frank Glaw of the Zoological State Collection of Munich. The animals live in leafy undergrowth in Madagascan forests.

Tiny and camouflaged - how did they find these guys? Most of the lizards were collected at night, when they typically climb up into the underbrush to roost. The field biologists used torches and headlamps to spot the sleeping lizards, according to their paper.

The paper appears in the open-access journal PLoS One.

PopSci's top picks of Toy Fair 2012 (or why you need an iPhone to have any fun anymore)

As one commenter for last year's annual Toy Fair wrap-up pointed out, there was once a time when Lincoln Logs were considered a cutting-edge toy. It was never so clear as it is now, though, that the heyday of the analog toy has long-since passed. 2012 shall be the year of the app-enabled toy.

Half of the playthings that caught our attention require an iOS or Android device to do, well, anything. But, in adapting an already-powerful handset as the brains behind anything from a toy gun to a board game, today's crop of high-tech toys are able to become more capable and more immersive than anything that's come before.

That said, special props go to the three toys in our list that require no batteries at all.

CleanSpace One, Chasing Down a Cubesat EPFL

The growing space junk problem in various orbits around the Earth gets plenty of ink these days, particularly when the ISS has to fire its thrusters to dodge a piece of a satellite, or when a defunct satellite smashes into a perfectly good, multimillion dollar piece of orbital communications hardware. Gathering up and disposing or all that fast-moving refuse makes for a difficult problem, but over at EPFL in Switzerland a team of researchers is developing a new kind of micro-sat that could help clean up low Earth orbit, starting by disposing of Switzerland's own leftover space debris.

CleanSpace One is a project aimed at building a prototype for a family of satellites that would chase down and capture small pieces of orbital debris. NASA is currently tracking some 16,000 pieces of junk larger than about four inches diameter, but the agency estimates there are many more times that ripping around the planet at orbital speeds (call it 17,500 miles per hour).

Each one is a disaster waiting to happen; orbital debris threatens satellites, spacecraft, and astronauts moving within and through its orbit, potentially costing lots of money or even human lives. All kinds of proposals for dealing with the problem--everything from trash collecting satellites to ground based lasers that would zap orbital debris from the sky--have been put forward, but so far nothing has gained traction. EPFL (that's the École Polytechnique Fédérale de Lausanne) hopes to change that.

CleanSpace One would not be a massive trash-collecting satellite, but a tiny trash-chaser designed to destroy exactly one piece of debris. The first target will be one of two small Swiss picosatellites launched in 2009 and 2010 that are still in orbit up there though their scientific missions are done. CleanSpace One would track down one of the satellites in its orbit, latch onto it with some kind of gripper, and drag it back into Earth's atmosphere where both would burn up on re-entry.

Simply doing so would require some key technology pieces, both of which EPFL is working to develop in-house, possibly employing a new brand of super-compact space motor currently in the lab there. It will also require some kind of gripping mechanism that can secure the targeted piece of debris and drag it downward.

Of course, at 10 million Swiss francs (that's about $10.8 million) it seems like an expensive way to capture small pieces of orbital trash. But the idea is to develop a suite of technologies and then a family of satellites designed purely to clean up orbit. Economies of scale and putting many of these small debris chaser on a single launch could drastically drive the cost of deployment down. Get a full rundown of the problem and the EPFL program below.

Video: Coffee-Filled Robot Paw Learns How to Throw

Throwing Darts John Amend, Cornell University

Our favorite grippy robot fist, the balloon filled with coffee grounds, has graduated from grabbing to throwing. Its developers at Cornell University and the University of Chicago have taught it how to hurl objects, from mini basketballs to darts.

Robotic hands that resemble our own can be elegant and useful, but they are expensive and tricky to make, which is why the Cornell/Chicago team developed the balloon fist instead. The Kinetic Object grippiNg Arm, or KONA, which we christened it when it was announced, conforms to the shape of whatever object you want it to pick up. The balloon presses down and deforms to fit the shape of the object, and then a vacuum removes the air from the balloon, solidifying its grip.

Its creators taught it to throw by reversing that process - rapidly re-filling the balloon with air. You might think this would cause a clumsy fumble as the carefully gripped object comes loose. You would be wrong.

While the game of darts is impressive, the shooting capability isn't accurate enough - at least not yet - for KONA to go to work in, say, a factory. But it could be a new way to give a robot more range, like sorting objects, doing laundry. throwing away garbage or flicking helpless toy soldiers off a table.

This new ability was apparently an accident, by the way. According to the Creative Machines Lab at Cornell, the engineers were working with the gripper and running into problems with repeated gripping tasks, because the balloon would sometimes get stuck in its vacuum-packed state. They reversed the air pressure to move things along and found a surprising performance increase.

The gripper team is publishing a paper on their robot in the IEEE journal Transactions on Robotics.

The Contestants From left: Mattel Fijit Friend "Willa", Tosy DiscoRobo, BeatBots MyKeepon Dan Bracaglia (3)
So they think they can dance? Three robots bust a move to try to win your vote, and be crowned Best Robotic Dancer

We may still be a long way from fully-functioning robot maids or dog-walkers, but there's one thing consumer robot-makers have figured out: how to make 'em dance. This year, three music-responsive 'bots will be on sale, leaving us to wonder: who's got the best moves? So we gathered up the three contestants and blasted some "Robot Rock." We'll leave it to you to decide who rocks out the best.

The Contestants:

BeatBots MyKeepon (yellow corner) He trained to dance at Carnegie Mellon University, and is most famed for his rendition of Spoon's "I Turn My Camera On." MyKeepon prefers to dance perched atop his own black podium as he bops. In his free time, he works as a therapeutic tool for children with autism.

Mattel Fijit Friend Willa (purple corner) Representing her entire Fijit Friend team, of which there are four, Willa moves, twirls and headbangs to any music you like -- all without the benefit of arms or legs. If you can't pick a song, she offers to sing her own, though we wouldn't recommend it.

Tosy DiscoRobo (blue corner) DiscoRobo traveled from Vietnam to compete in the dance-off, confident he could best his competitors with his own brand of pop-and-lock moves -- not to mention articulating arms, moving legs, and wheels. We'll just have to see...

More Drones are Coming to U.S. Airspace U.S. Department of Homeland Security
First responders will be cleared to operate small drones in U.S. airspace in just three months

Just a week after Congress finally passed an FAA spending bill requiring the aviation regulator to expedite the integration of unmanned aerial systems (UAS) into the national airspace, President Obama has already signed it into law. What does that mean? The bill requires full integration of UAS into the national regulatory framework by Sept. 30, 2015, but you'll start seeing drones in the sky sooner than that. Small UAS (under 55 pounds) must be cleared to fly by mid-2014. And emergency first responders will be able to pilot very small UAS (4.4 pounds or less) within just 90 days.
