In the midst of controversy proclaiming WiFi as the harbinger of brain tumors, it’s nice to hear that wireless might actually be doing us some good. The same technology that lets you jabber into your Bluetooth earpiece can also let your doctor know you’re having a heart attack.

Every year, 935 million packs of gum are chewed by 28 million Britons, leaving millions of sticky, inconvenient lumps in their wake. The globs can only be removed with high pressure steam hoses, expensive freezing machines, or corrosive, environmentally unfriendly chemicals, costing taxpayers £150 ($300) million per year. The desperate state of affairs has attracted millions of dollars of research into non-stick chewing gum, but the country wants a quicker solution.

Robots may not only be cleaning your house and providing you with love and companionship in the coming years—they may also be performing your surgery. A team of engineers at Duke University have completed a set of feasibility tests that they call the “first concrete steps” toward making robot surgery a fully, er, operational process.

No, it’s not the second coming of the Flying Spaghetti Monster—but it’s just as awesome. AirJelly, a remote-controlled helium balloon, was built by engineers at the Swiss Materials Science & Technology Development (EMPA) in Dübendorf, who were inspired by the jellyfish’s endurance through evolutionary time.

Researchers at the department of Applied Physics of the Hebrew University of Jerusalem can smell a lie from a mile away. Or, at least, they can detect changes in levels of perspiration from about 10 inches away, using millions of tiny antennae that cover our bodies—sweat glands.

Sweat glands, it turns out, are shaped like tiny coils. Physicist Yuri Feldman had been spending a bit too much time in the applied physics lab, and when he saw the shape he thought of helical antennae in wireless communication systems. This gave them an interesting idea: The ducts might be able to send out an electromagnetic signal, enabling remote sweat detection.

There are some things that most people think should never be made out of wood—things that produce extreme heat through a combustion process, say, or things that could collide with an oncoming semi at 190 mph while carrying human cargo. But you never know unless you try—so a group of industrial design grad students at North Carolina State are taking on the absurdly ambitious, and very cool, task of building a high-powered, high-speed automobile out of wood, held together mostly by glue.

The specs are impressive—over 600 hp, top speed of 190 mph, zero to 60 in just over three seconds, 2,500 pounds, and 20 mpg—but it’s all pretty hypothetical at the moment (as are, I assume, the Lambo-style doors). But the aptly named “Splinter” isn’t just a bunch of two-by-fours nailed together. The students are using the project to explore the potential of wood as a building material, so pretty much every part contains wood composites, like plywood. The car also contains a fair amount of glass and metal—including the shocks and a Cadillac Northstar sourced V-8 combustion engine.

When life gives you 20 million pigs’ worth of urine, make pig-piss-flavored cigarettes. Or, if you’re not a smoker, use the pig pee to make plastic dinnerware and fuel your car, or smooth it over your body for soft, supple hair and skin. Agroplast, a Denmark-based company, hopes to use its country’s surfeit of pig waste—the cause of contaminated ground water, dying plants, noxious air, and pissed-off neighbors—to make useful household products, from plastics to hair conditioner.

• The hottest country code on teh Internets [sic]: .su—as in, the Soviet Union. Which, in case you somehow forgot, doesn’t exist anymore.

• Big prizes are spurring a new age in (and at least one blog about) space exploration. Now PETA hopes to do the same with a $1 million prize to the first mad scientists who can “produce commercially viable quantities of in vitro meat at competitive prices by 2012,” thereby sparing real animals from becoming meat. Note the stipulation about “commercially viable,” you home molecular gastronomists.

Michael Arrington at TechCrunch reports that an American journalism student has been “saved” from jail in Egypt by using Twitter, the trendy “micro-blogging” site that lets people send micro-meaningful text messages to all their ostensible friends. UC Berkeley graduate student James Karl Buck found himself in hot water when Egyptian police arrested him, on no charge, while he was photographing a demonstration. Buck wasted no time in text messaging the word “Arrested” to his Twitter network of 48 people.

Steve Freeman, a visiting professor at the University of Pennsylvania, compared the vulnerabilities of the two in his book, with some pretty alarming results. Among the problems he found:

–Unpredictable voting machine software is kept secret, while gambling software must be kept on file with the state.

–State inspectors randomly inspect gambling machines to ensure their software and computer chips haven’t been tinkered with. Voting machines don’t need to be checked, and no one knows what’s in them anyways.

–Slot machine manufacturers are subjected to background checks, while no one knows whether voting machine programmers have been convicted of, say, fraud (video).

–Gambling equipment is tested and certified by third parties, while voting machines are certified by companies of the manufacturer’s choosing (and payroll).

–In case of dispute, gamblers have access to round-the-clock investigators who can analyze machines. Disgruntled voters can (sometimes) file a complaint that may or may not be investigated. (more…)

I think it’s reasonable to assume that ever since the dawn of humankind, people have yearned to control lightning. (No, Halle Berry did not create this idea for her role in X-Men.) The first approach—rain dances, spells, and the like—proved marginally effective, at best, but there wasn’t much of an alternative. In the ’70s, scientists found out that if they launched rockets carrying long metal wires into thunderstorms, the wires would sometimes provide enough conductance to coax a lightning strike, much like Ben Franklin’s (probably apocryphal) kite string. But around the same time, they also thought it would be much, much cooler to use a laser to bring about lightning. Most things are cooler when accomplished by lasers, as any scientist can tell you.

A group of European researchers working at South Baldy Peak have finally realized this longstanding goal by successfully bringing about lightning by zapping lasers into thunderclouds in a recent experiment. The ultrashort laser bursts (only around a hundred femtoseconds) ionize some of the molecules in the air, forming a plasma, and these channels of plasma act can guide lightning strikes like the wires on a rocket.

• Are stars secretly zombie cannibals? A new study suggests that “dead” stars may consume their healthy neighbors, thus creating a large and mysterious cloud of antimatter in the center of the galaxy. Look for George Romero’s take, coming soon to a theater near you.

• A Bosnian man claims his home has been targeted by aliens, after the house was hit by meteorites five times. But before you write him off, consider this: Experts at Belgrade University have confirmed that the rocks are genuine. (more…)

On Sunday at New York’s Javits Center, hundreds of teens gathered to compete in the finals of the FIRST Robotics Competition regionals. The winners will go on to the National Competition in Atlanta—for the rest, this competition was the end of the assembly line.

On the track, the competition was fierce and students eyed each others’ handiwork warily. But behind the scenes in the pit, where goggle-clad kids wielded screwdrivers and tinkered with their machines, the students shared their knowledge with each other, with experienced groups often lending a hand to first-timers. The Capri-Sun flowed freely.

Robots burned rubber in the ring today at the Javit’s Center for the regional championship of FIRST (An acronym DISCOVER can get behind: “For Inspiration and Recognition of Science and Technology”). Keep checking in on Discoblog for a full recap of the event. For now, here is a recap in photos of the innovation, competition, and robotic mayhem that took place today among high schoolers and engineers showing off their circuitry skills.

There are three objects in this game: 1) Be quick—the more laps, the more points 2) Knock down balls. 3) Pick the balls back up and place them on top of the bars or shoot them over.

Over one thousand high school students scurry around 64 robots along about the floor of the Javits Center in New York City. They are here to compete in the NYC regional contest to prove they have what it takes to put together the fittest, most agile, robot to rule them all. In this year’s competition the students, with the help of their teachers and outside engineers, designed robots that will fight—well, let’s say “compete”—to move on to the nationals (and get a shot at scholarship money) in a game of Overdrive.

The goal is simple: two teams of three robots each race around a 1500-square foot track, earning points for successfully completing each lap. On top of this teams can get points for manipulating huge red and blue balls that sit atop a 6-ft-plus scaffold in the middle of the track. The robots get 6 points for bringing the balls down and 8 points if they can hoist them back up.

The last time you were in an airport, did you feel your heart rate jump at the sight of vigilant German Shepherds sniffing your bags? While your suitcase may have been entirely contraband-free, the idea that smells, often uncontrollable and undetectable to the human nose, can reveal secrets about you is enough to make even a seasoned traveler nervous.

Use of odor detection by law enforcement is on the rise, as defense attorney and surveillance expert Amber Marks writes in the Guardian. For police forces worldwide, smells are being increasingly relied on to detect drugs, weapons, and stolen goods. A smell alone, in the U.K. at least, can even be considered sufficient evidence to convict someone of a crime. Meanwhile, the technology of smell detection is rushing to meet tightened security needs: canine trainers are teaching dogs to sniff out emotions such as guilt and fear, while electronic noses can now be programmed to identify the “odor signature” of different races or ethnic groups.

If you feel immobilized by the latest bump in gas prices, just follow these five simple steps:

1. scour through the rotting dregs of your kitchen’s garbage cans, collect all animal and plant products (the fouler the better)
2. toss a few billion garbage-loving bacteria into the decaying sludge
3. give the microbes a few days to breed and ferment
4. discard gelatinous muck, save all gases emitted
5. enjoy your environmentally friendly energy!

Last Friday night between 10:15 and 10:30 pm, six airplanes flying into Sydney Airport were victims of the city’s first coordinated laser attack, in which some miscreants shined lasers at the folks operating the flying tin cans carrying lots of people. The potentially dangerous maneuver provoked the government to consider banning laser pointers or classifying them as illegal weapons. (Shining laser beams at aircraft is already punishable by two years’ jail time and fines of up to $30,000.)
