A Naked Engine For Cleaner Flights

Popular Science - March 20, 2010 - 5:15am

A jet engine shelved in the '80s could improve airplane fuel economy today

In 1983, engineers at General Electric experimented with an "unducted fan" engine. Without the external casing, airflow through the blades increased, delivering more power for the same amount of fuel. The thing was loud, but the company pressed on because the trick could reduce fuel consumption by as much as 26 percent. Then fuel prices dropped, gas guzzling became acceptable, and GE mothballed the project. Now that airlines are again conscious of fuel costs and carbon, the idea is back, and new tech is making it feasible. Read more »

Video: F-35 Performs Its First Fully Vertical Landing

Popular Science - March 20, 2010 - 3:47am

After cost overruns, a series of delays, and almost a decade of hype, the F-35 Lighting finally performed a vertical landing for the first time. Yesterday at 1 P.M., after descending from a 150-foot-high hover, the test plane touched down on the tarmac at the Patuxent River Naval Air Station. This is a significant step forward for the F-35, as its vertical takeoff and landing capability are crucial to the fighter's role as a replacement for the aging Harrier jet.

The test began with a short runway takeoff at 93 miles per hour, after which the pilot swung around, positioned the plane over the runway, and lowered it down. The test pilot, a former Royal Air Force aviator with experience piloting VSTOL planes, said he found landing the F-35 vertically far easier than landing older planes, like the Harrier, the same way.

A Mariner's Tool Could Help Astronauts Navigate Alien Worlds

Popular Science - March 20, 2010 - 2:16am

Like GPS for marstronauts

It will probably take another decade to perfect the sophisticated rocket and life-support technology needed to put a human on Mars. But once we're there, NASA may use centuries-old technology to keep us from getting lost during a stroll.

Apollo crews never left sight of their capsule, but explorers will be expected to roam farther on the Red Planet. Mars, however, like the moon, lacks a strong magnetic field to point a compass needle north. This conundrum inspired Richard Speck, the founder of space-tech company Micro-Space, to design a camera system that tracks celestial bodies for personal navigation cues. It uses the same principle as the sextant, the sun-mapping tool invented in 1731 for sailors to plot their course. Read more »

Most Flawless Diamonds Ever Are Meant for Lasers, Not Rings

Popular Science - March 19, 2010 - 8:45am

Scientists need the diamonds to build the next generation of X-ray lasers

Powerful X-ray lasers may allow scientists to image tiny drug molecules or even precisely target cancer cells, but the lasers require extremely high-quality mirrors to function well. Now researchers have created a nearly-flawless diamond that can do the job, according to Discovery News.

One X-ray laser already exists in an underground facility at the Stanford Linear Accelerator Laboratory, where it spans several football fields in length. A backlog of experiments in biology, physics and chemistry has already formed, which led to the need for more X-ray lasers.

Most lasers use silicon mirrors to bounce light wavelengths back and forth, but silicon can't reflect powerful X-rays. That's where diamond mirrors entered the picture. Read more »

From Malaysian Architects, a Parallel Prison World in the Sky

Popular Science - March 19, 2010 - 7:19am

The designers were inspired by the idea of prisoner rehabilitation

Prisoners pose an age-old dilemma for societies: try to keep them separated from the good citizenry while possibly easing some of the black sheep back into the fold. Now Malaysian architecture students have hit upon the solution of a sky prison city that allows prisoners to work in farms and factories to contribute to the host city below, CNET reports.

Convicted criminals, prison employees, and cargo would shuttle back and forth to the great big prison in the sky on pods that travel on the prison's supporting structural legs. Different pod types include a heavy lift cargo pod, a medevac pod, and an armored riot control pod that drops police on lines, commando-style. Read more »

Australian Study Finds Possible Treatment to Make Smoking Healthier for Lungs

GM Turning Car Windshields into Augmented-Reality Navigation Displays

Popular Science - March 19, 2010 - 3:44am

Still doesn't excuse driving one-handed while texting

Distracted drivers may soon get some warnings from their windshield displays about road hazards such as children playing in the street or vehicles in the driver's blind spot. General Motors has teamed up with university researchers to bring the concept to market around 2016, the New York Times reports.

The enhanced vision system would monitor a driver's eye and head movements via sensors located both inside and outside the vehicle. The display would then overlay enhanced views of the road on top of the actual scene visible through the windshield. GM hopes that the augmented reality (AR) windshield display can allow drivers to view GPS directions without looking away from the road, and cope with difficult driving conditions in fog or at night.

Rescue Workers Can Prevent Brain Damage with Icy Nasal Spray

Popular Science - March 19, 2010 - 1:50am

After cardiac arrest, lowering someone's body temperature can prevent life-threatening brain damage. It's so critical that New York City requires ambulances to take some patients up to 20 minutes out of the way to hospitals with cooling equipment. EMTs could improve patients' chances further using RhinoChill, a new portable nose spray that cools the brain on the scene.

In the past decade, doctors learned to safely induce hypothermia to slow brain cells' metabolism, preventing the buildup of toxic molecules that can cause lasting damage. Many hospitals insert a refrigerated tube into a major vein, a technique too dangerous to attempt in the field.

To take the treatment on the road, medical company BeneChill left the refrigerator behind. The key is a fast-evaporating liquid that, squirted up the nose, cools the brain. Read more »

DARPA Wants Roving 'Smart Cameras' That Understand What They See

Popular Science - March 18, 2010 - 8:16am

The problem with surveillance cameras is that they can see but they can't think, which means there always has to be a human on the other end making cognitive sense of what's right in front of the camera. But if we meshed machine vision with visual intelligence, DARPA argues in a solicitation for its new "Mind's Eye" program, we could remove the human element from myriad tasks.

In essense, DARPA wants a smart camera that not only sees what's in front of it, but thinks about what's going on and even what might happen next. Read more »

Shortage of Rare Earth Minerals May Cripple U.S. High-Tech, Scientists Warn Congress

Popular Science - March 18, 2010 - 6:47am

On the sunnier side, rare earths could power a future generation of clean tech

All those hybrid and electric cars, wind turbines and similar clean tech innovations may count for nothing if the U.S. cannot secure a supply of rare earth minerals. Ditto for other advanced telecommunications or defense technologies, scientists told a U.S. House subcommittee.

China has supplied 91 percent of U.S. consumption of rare earths between 2005 and 2008, and continues to represent the world's largest rare earth exporter. But the Chinese have warned that their own domestic industry appetite for rare earths may eventually force them to stop exporting -- an action that would leave the U.S. high-tech industries crippled without other readily available supplies.

MIT Cybersecurity System Can Keep Servers Functioning Even During Attack

Popular Science - March 18, 2010 - 3:58am

One of the major problems with current cybersecurity measures is that while systems can detect the erratic behavior that heralds an incoming attack, there often isn't a whole lot those systems can do once the attack is underway short of pulling the servers offline, resulting in lost revenues and credibility for Web sites and a loss of key services for users. A new MIT system aims to change that by keeping servers and applications running even as it contains an incoming cyberattack.

The system works by observing programs as they normally run and memorizing those ranges of behavior. During an attack, the system simply locks the programs within those behavioral ranges; that is, if a program usually stores data at either location X or location Y, those are the only two places it will be allowed to store data once the security system detects that an attack is underway.

NASA and U.S. Navy Pledge to Save Silicon Valley's Massive Airship Hangar

Popular Science - March 18, 2010 - 2:28am

The landmark Hangar One needs a giant new Teflon skin to replace its toxic siding, but funding is an issue

Hangar One's behemoth structure once housed airships such as the doomed U.S.S. Macon, and is so large that clouds can supposedly form and rain inside it. Now NASA and the U.S. Navy have promised to replace the hangar's toxic siding with a new Teflon-covered fiberglass fabric skin, The Register reports.

But that can only happen if NASA can somehow scrape together $15 million to $40 million for the job -- the Navy has only taken responsibility for removing the old siding. The U.S. space agency is considering turning to private development funds to restore the hangar, according to the Mountain View Voice. Read more »

Humans Could Regenerate Tissue Like Newts Do By Switching Off a Single Gene

Popular Science - March 17, 2010 - 8:15am

Scientists have long been stymied by human regenerative healing -- that is, wholesale regrowth of, say, a severed limb -- an ability inherent in some species but lost on humans. But new research suggests the ability to regenerate isn't based on something newts and flatworms have that we don't; rather, it's something we do have that's keeping us from regenerating tissues. Researchers think a gene called p21 may control regenerative healing, and that by switching it off, humans could perform our own regeneration.

The new research suggests that the potential to heal without scarring -- or possibly even to regrow a limb, albeit in a limited manner -- may lie dormant in human cells, kept in check by the p21 gene. A group of lab mice engineered to lack p21 were able to regenerate surgically removed tissue to the point that no evidence of the surgery remained. Holes punched in their ears -- a standard procedure for tagging lab animals -- also healed perfectly, leaving behind no traces of scar tissue or previous damage. Read more »

In 2020, Take a High-Speed Train from Beijing to London

Popular Science - March 17, 2010 - 6:44am

Chinese rail passengers already zip between cities on trains traveling three times faster than the average train in the States, and a 217-mph line linking Wuhan and Guangzhou will soon be the fastest train on Earth. But not content with screaming-fast trains linking cities within its borders, China now plans to extend its high-speed network all the way to London with a rail line that will fly through 17 countries at speeds reaching 200 miles per hour.

The project calls for the construction of three lines, hopefully by 2020: the first will link London's King's Cross Station to Beijing and take approximately two days to traverse the entire stretch (it will then continue on down to Singapore). A second line will connect China with Southeast Asian nations like Vietnam, Thailand and Malaysia. The third line will link Germany and Russia, crossing Siberia to terminate, of course, in China.

Bacteria on Your Hands Could Become New Forensic Fingerprint

Popular Science - March 17, 2010 - 2:58am

The cats over at CSI might just have another forensic tool to supplement their super-sleek glass and steel science lab: the bacteria on our hands. A group of researchers at University of Colorado Boulder have conducted a proof-of-concept study in which they were able to accurately identify people using samples of bacteria collected from their computer keyboards and mouses.

As it turns out, even the most obsessive-compulsive among us carry about 150 species of bacteria around on our hands, and those bacteria in turn carry a genome unique to that person. Those bacteria could potentially become a damning forensic tool at crime scenes, allowing investigators to gather DNA information unique to a perpetrator even without recovering any of that person's actual DNA.

New Understanding of Natural Silk's Mysteries Could Lead to Stronger, Lighter Materials

Natural silk, as we all know, has a strength that manmade materials have long struggled to match. In a discovery that sounds more like an ancient Chinese proverb than a materials science breakthrough, MIT researchers have discovered that silk gets its strength from its weakness. Or, more specifically, its many weaknesses. Silk gets its extraordinary durability and ductility from an unusual arrangement of hydrogen bonds that are inherently very weak but that work together to create a strong, flexible structure.

Better Meds: Scientists Identify Key Genetic Components for Morphine Synthesis

Popular Science - March 16, 2010 - 7:16am

How poppies do their thing

Morphine is potent, effective and in many cases the only pleasant aspect accompanying a visit to the surgeon. But the opium from which it is derived is the base ingredient for heroin and a politically problematic cash crop in places like Afghanistan. Now researchers working to unravel the morphine synthesis process have figured out two of the final, critical steps in that chain reaction, which could lead to better production methods and cheaper opiates like codeine and oxycodone -- not that we have any clear idea what these fantastic, euphoria-inducing painkillers do inside the body.

The breakthrough centers on a couple of key enzymes that kick off the chemical reactions that convert the chemical precursors thebaine and codeine into morphine. The University of Calgary researchers identified the enzymes as well as the genes that encode them with their unique catalyzing capability, then used that information to verify their work through experimentation.

The experiment transmitted 10 Mbps through a person

Human skin is apparently a very energy-efficient conduit for transmitting data. A recent experiment achieved a rate of 10 megabits per second, which may put my Internet connection to shame. The experiment used small, flexible electrodes and took place at Korea University in Seoul, New Scientist reports.

The finding may lead to a new generation of medical devices that can monitor blood sugar or electrical activity in the heart. Such devices cut energy needs for a monitoring network by about 90 percent compared to wireless devices running on batteries.

South Korean researchers placed electrodes about 12 inches (30 centimeters) apart on a person's arm, and found that the low-frequency electromagnetic waves travel easily through the skin without any outside interference. Read more »

A bright idea coming out of Germany's Fraunhofer Institute could change the way we connect to the Internet in the future, as well as drive the nascent market for interior LED lighting. Researchers there have found a way to encode a visible-frequency wireless signal in the light coming from lamps and fixtures, turning the light that surrounds us into a high-speed broadband source.

That's not to say there's anything particularly wrong with radio-frequency wi-fi, but its limited bandwidth restricts it to a certain spectrum within an already crowded field of signals. It also leaks through walls -- a benefit for signal pirates but a detriment for those who want a signal that is both secure and free of interference. Read more »

They don't exactly look like the saviors of our energy economy, but that's exactly what some researchers think they could be. Gribbles -- tiny crustacean pests with a knack for digesting wood -- have long been considered a marine parasite for the destruction they cause to wooden hulls and piers. But the enzymes gribbles use in to break wood fibers down into sugars could make them the next biofuels breakthrough.

Essentially, gribbles are blessed with a digestive process unparalleled (to our knowledge) by other wood-consuming insects and animals. Their digestive enzymes can break down woody cellulose and even lignin -- the normally indigestible part of woody plants -- creating sugars that are more or less ideal for fermenting into alcohol-based fuels.

As a few of the comments on the post and on Make suggest, a particle counter, though spendy, would be key to gauging success and pinpointing issues with the cleanroom. Without some quantification, it is impossible to meaningfully measure the performance of the clean room. This shouldn't take anything away from the clean room build, but hopefully it will inspire a DIY particle counter solution from our readers. Anyone? Read more »

Space Station Experiment Tests How Biofuel Crop Grows in Zero G

Popular Science - March 9, 2010 - 8:37am

Can space farms provide biofuels for a greener Earth?

Future biofuels from space could be go for launch, if a space station experiment shows that microgravity can favorably affect the growth of Jatropha curcas plant cells. Jatropha can produce high-quality oil that represents one of the more promising possibilities for a source of alternative energy.

The National Lab Pathfinder-Cells 3 experiment launched aboard the space shuttle Endeavour's mission in February. The plant cells will endure the microgravity environment inside their flasks containing nutrients and vitamins, until they return to Earth aboard the space shuttle Discovery mission slated for April.

Heat-Channeling Carbon Nanotubes Produce 100 Times More Energy than Li-ion Batteries

Popular Science - March 9, 2010 - 5:44am

"Thermopower waves" could be a brand-new way to produce electricity

Johnny Cash can't have known about carbon nanotubes when he sang about that burning ring of fire, but MIT scientists have shown how the tiny tubes can channel a ring of heat that creates electrical current -- about 100 times as much energy per unit of weight when compared with a lithium-ion (Li-ion) battery.

The new experiments involved nanotubes, or submicroscopic structures just a few billionths of a meter in diameter, that can conduct both electricity and heat. Engineers coated the nanotubes with reactive fuel that produces heat by decomposing, and then ignited it with laser beams or high-voltage sparks. Read more »

Video: Boeing 747 Withstands Simulated What-If Underwear Bomber Blast

Popular Science - March 9, 2010 - 4:14am

The bomb blast was meant to gauge what might have happened if the Flight 253 suicide bomber succeeded

An explosion aboard Flight 253 on Christmas Day would not have crippled the Boeing 747, according to a recent test that simulated the success of would-be bomber Umar Abdulmutallab. Only the bomber and passenger next to him would have died, the BBC reports.

The test plane didn't quite get away without a scratch, but it only lost some rivets and suffered an outward dent. The flight controls and fuel tanks appeared safe post-blast to Captain J Joseph, an air accident investigator, and John Wyatt, an international terrorism and explosives adviser to the United Nations.

U.S. Cybersecurity Czar Says "There is No Cyberwar"

Popular Science - March 6, 2010 - 7:58am

Howard Schmidt wants U.S. cybersecurity efforts to refocus on education, information sharing, and better defense systems

Obama's new cybersecurity czar doesn't much like the term "cyberwar," calling it a "terrible metaphor" and a "terrible concept." But just in case his dislike of the term didn't get through, Howard Schmidt flat-out stated that "there is no cyberwar" during a Wired interview at the RSA Security Conference in San Francisco.

Schmidt noted that the real cybersecurity threats are online crime and espionage. His words seem to stand in contradiction to a statement last week by Michael McConnell, former director of national intelligence, who told Congress that the U.S. was already in the midst of losing a cyberwar. Schmidt seemed more than willing to downplay McConnell's Cold War mentality. Read more »

New Brain Scan Quantifies The Formerly Subjective Feeling of Pain

Popular Science - March 5, 2010 - 4:39am

The seemingly subjective nature of pain always proves problematic for doctors, who have to use a woefully imprecise chart to gauge a patient's suffering. But by using a new interpretation of fMRI scans, doctors at the University of Oxford have found a way to measure the brain's pain response in a quantitative way. Aside from providing a more precise tool for doctors, this technology may also enable doctors to measure pain in people with locked-in syndrome, people in vegetative states, pre-verbal children, animals, and fetuses.

Your cellphone does not in itself cause cancer. But in the daily sea of radiation we all travel, there may be subtler dangers at work, and science is only just beginning to understand how they can come to affect people like Per Segerbäck so intensely

Per Segerbäck lives in a modest cottage in a nature reserve some 75 miles northeast of Stockholm. Wolves, moose and brown bears roam freely past his front door. He keeps limited human company, because human technology makes him physically ill. How ill? On a walk last summer, he ran into one of his few neighbors, a man who lives in a cottage about 100 yards away. During their chat, the man's cellphone rang, and Segerbäck, 54, was overcome by nausea. Within seconds, he was unconscious. Read more »

An Implantable Glucose Sensor Could Help Diabetics Stay Healthy

Popular Science - March 4, 2010 - 3:35am

Nurses usually pluck splinters from people's flesh, not put them in. But a new rice-size implantable glucose sensor that monitors blood sugar all day might mean less pain for diabetics.

A nurse would inject the sensor, called Glucowizzard, in a patient's wrist and fit him with a wristband that powers the chip's photovoltaic cells by flashing light pulses through the skin. The chip works like conventional monitors: An enzyme reacts with glucose in the blood and frees electrons in proportion to sugar levels. The chip senses the electrons and beams data to the bracelet, which pings the user if sugar levels are extreme. Running continuously, it could detect problems that might be missed by current finger-prick monitors, which are typically used only five times day. Read more »

The mismanagement of human waste is a serious health problem for the 2.6 billion people who don't have regular access to toilets. In fact, in the slums of Kenya, waste management is so haphazard that residents dispose of feces-filled plastic bags by simply flinging the bags away without concern about where they land.

One Quarter of Germans Would Embrace an Implantable Microchip

Popular Science - March 3, 2010 - 6:15am

Privacy-loving Americans have roundly rejected the idea of implanting microchips within their bodies, but one in four Germans is enthusiastic about the idea of having a chip implanted as long as there are tangible benefits involved. Those benefits don't even have to be of the life-and-death nature; some said they would implant a chip simply to make a shopping experience more enjoyable.

A poll released Monday in anticipation of Europe's CeBIT trade show indicated that 23 percent of Germans are open to the idea of implantable microchips. The largest contingent (16%) said they would do it to help emergency services respond to them more quickly and effectively in case of an accident.

Another 5% would do it for mere convenience, to make everyday tasks like shopping go more smoothly. Purchasing goods simply by carrying them past sensors on the way out of the store? Seems feasible enough, though the opportunities for fraud and theft would likely discourage such a scheme. Read more »

VTOL Drone Would Land, Refuel and Take Off By Itself

Popular Science - March 2, 2010 - 4:15am

No really, you can let go

Drones can do just about everything autonomously these days, but most systems still require human assistance to land, refuel and take off again. Now, an aerospace startup, Aerovel, hopes to change that with its hover-capable Flexrotor drone that will come with its own automated docking station. No human ground support needed, The Register reports.

The notion comes from Tad McGeer, a Silicon Valley entrepreneur who created the small ScanEagle drone for fishermen and U.S. Navy SEALS. ScanEagle relied upon a pneumatic catapult launcher and "SkyHook" recovery pole, but the Flexrotor would do away with either requirement.

Instead, McGeer envisions his new drone using VTOL (vertical takeoff and landing) abilities. Tiny wingtip thrusters would do the same job as a helicopter's tail rotor and counteract the torque of the drone's main propeller in hover-mode. Read more »

A plastic skin impregnated with printed sensors could be wrapped around an airplane wing, for instance

Microelectromechanical devices (MEMS) have the potential to enable a wide range of nanomachines. Unfortunately, MEMS suffer from the critical drawbacks of an expensive manufacturing process, a high rigidity that restricts their use, and a limited pool of suitable materials for construction. Now, it seems that MIT scientists have accidentally solved all those problems by stamping gold MEMS into a sheet of plastic.

Video: A Silent Rotor Blade Paves the Way for Super-Stealth Choppers

Popular Science - February 27, 2010 - 8:33am

For all the government conspiracy militia nuts out there, I've got some good news and some bad news. The good news is that there is no such thing as silent, stealth black helicopters. The bad news is that, thanks to Eurocopter's noise-canceling Blue Edge rotor blades, there soon will be.

The extremely loud noise made by helicopter blades results primarily from the blades chopping through eddies in their own wakes, a phenomenon known as blade-vortex interaction. By changing the shape of the rotor blades, Eurocopter manages to pair down the blade-vortex interaction so thoroughly that the sound only reaches the whisper volume of 3 or 4 decibels.

With cuts in the manned space program and the impending retirement of the Space Shuttle, NASA will soon face the need to repair satellites without the ability to send any astronauts to do it. Fortunately, they're already working on the solution: robots.

Over the next seven months, NASA will finish installing the Dextre robot on the International Space Station (ISS). Once fully affixed to the ISS, Dextre, which previously helped astronauts repair the Hubble Space Telescope, will practice refueling satellites.

Once complete, Dextre will remove insulation from the outside of the ISS, disconnect safety wires, and eventually dock with and pump fuel through fuel ports on the ISS. The ISS fuel ports resemble the ports on most satellites, so Dextre's operators can test different configurations for problems and efficiency. Read more »

New Answer to 80-Year-Old Question Makes Computer Modeling 100,000 Times Faster

Popular Science - February 27, 2010 - 2:31am

Fermi would approve

A new formula allows computers to simulate how new materials behave up to 100,000 times faster than previously possible, and could drastically speed up innovation relating to electronic devices and energy-efficient cars. Princeton engineers came up with the model based on an 80-year-old quantum physics puzzle.

Llewellyn Hilleth Thomas and Nobel laureate Enrico Fermi first theorized in 1927 that they could calculate the energy of electrons in motion based on how electrons are distributed in a material. Knowing that kinetic energy of electrons in a material helps researchers understand the structure and properties of new materials, as well as how they might respond to physical stress.

But the Thomas-Fermi equation was based on a theoretical gas with electrons distributed evenly, and so it could not work for imperfect real materials. Read more »

Dubbed Recognizr, the app essentially works like this: the user points the camera at a person across the room. Face recognition software creates a 3-D model of the person's mug and sends it across a server where it's matched with an identity in the database. A cloud server conducts the facial recognition since and sends back the subject's name as well as links to any social networking sites the person has provided access to. Read more »

Hover-Chair Brings Senior Citizen Air Hockey One Step Closer To Reality

Popular Science - February 24, 2010 - 2:44am

Never at a loss for creative ways to make aging look like more fun than it is, the Japanese are developing an approach to senior mobility that's far more like a hovercraft than the mis-named Hoveround. Researchers there have engineered a chair that floats on a cushion of air, gently cruising above the floor like a puck on an air hockey table.

The prototype, designed by Tsunesuke Furuta and colleagues at Japan's Kobe Gakuin University, can be fitted with a performance-style car seat as well as a zabuton -- that's a Japanese-style floor cushion -- and reportedly can corner with ease while transporting a 330-pound payload.

The research team at Kobe Gakuin is looking for a commercial partner to help develop their hover-chair. In the meantime, you can see it in action below. Read more »

Acoustic Metamaterials Could Make Ultra-Thin, Ultra-Effective Noise-Cancelling Panels

Popular Science - February 24, 2010 - 1:18am

Hong Kong researchers have combined simple latex with some plastic buttons to create metamaterial panels that can stop sound waves very effectively, according to New Scientist. The reflected sound waves include low-frequency bass sounds that typically manage to sneak through the walls.

Thick pieces of certain materials, such as the commonly used foam, can typically absorb or reflect sounds, but creating a thin soundproofing material that can block low-frequency sounds has proven extremely difficult. For instance, a thin latex membrane by itself cannot resonate at the right frequency to either absorb or reflect the bass rumble of a jet taking off. Read more »

Obama Pledges $475 Million to Rescue Great Lakes

Top threats include toxic contamination, loss of wildlife habitat and invasive species

Pollution and ravenous Asian carp may threaten the U.S. Great Lakes, but the Obama administration has now put forth a four-year, $475-million rescue plan that would clean up the huge lake ecosystem and institute a "zero tolerance policy" against future incursions by invasive species, AP reports.

The Great Lakes supply drinking water to more than 30 million people, and also support regional shipping, outdoor recreation, tourism and manufacturing. This latest effort goes toward fulfilling a campaign pledge by President Obama to spend $5 billion over a decade on rescuing the lakes, and will launch under the aegis of the Environmental Protection Agency.

Scorpion Venom Could Make a Safe Alternative to Morphine

Popular Science - February 23, 2010 - 4:41am

Scorpion venom and intense pain generally go hand in hand, but a group of researchers at Tel Aviv University are rethinking that relationship, using a better understanding of the peptide toxins found in scorpions' pain-inducing payloads to create a breed of non-addictive, side effect-free painkillers.

Pain is communicated to the brain via a certain type of sodium channel embedded in our nervous and muscular systems. Understanding the way these sodium channels convey the sensation of pain from certain parts of the body to the brain is key to manipulating these signals to reduce or eliminate feelings of pain. Figure out how to manipulate those mechanisms, and we could be on the way to a much less painful future. Read more »

Future Electric Cars Could Earn Money for Owners While Sitting Still

Popular Science - February 20, 2010 - 8:58am

Cars could shed their image as energy hogs and become mobile storage points for the electric grid, if engineers backed by the National Science Foundation get their way. Hybrid electric vehicles might even feed unused electricity back into the grid and earn money for their owners, not unlike how some homeowners who create renewable energy can sell back electricity to utility companies.

The concept of vehicle-to-grid (V2G) integration would do away with simply considering hybrid electric cars as energy consumers that require stations or places to plug into the electric grid and recharge their batteries.

"Cars sit most of the time," said Jeff Stein, a mechanical engineer at the University of Michigan who leads the NSF-funded effort. "What if it could work for you while it sits there?" Read more »

Ultrasound Beams Could Destroy Stroke-Causing Blood Clots in the Brain

Popular Science - February 18, 2010 - 10:09am

Physicians usually rely on surgery or drugs to bust blood clots in the brain that might otherwise cause a stroke, but sound waves might provide a third noninvasive choice. U.S. researchers have begun testing an Israeli ultrasound device to see whether it may prove accurate enough to break up a clot without causing collateral damage in the brain, Technology Review reports.

Strokes represent the third most common cause of death in the U.S., and occur when a blood clot prevents blood from reaching the brain. Only drugs or surgical intervention can remove the clots in time to prevent serious brain damage or death, but fewer than 10 percent of patients usually fit the requirements to undergo those procedures.

Dumping all our nuclear waste in a volcano does seem like a neat solution for destroying the roughly 29,000 tons of spent uranium fuel rods stockpiled around the world. But there's a critical standard that a volcano would have to meet to properly dispose of the stuff, explains Charlotte Rowe, a volcano geophysicist at Los Alamos National Laboratory. And that standard is heat. The lava would have to not only melt the fuel rods but also strip the uranium of its radioactivity. Read more »

Science fiction writers may have to rethink how their starship crews survive travel near or beyond the speed of light. Even the occasional hydrogen atom floating in the interstellar void would become a lethal radiation beam that would kill human crews in mere seconds and destroy a spacecraft's electronics, New Scientist reports.

Just a few stray wisps of hydrogen gas -- fewer than two hydrogen atoms per cubic centimeter on average -- would translate into 7 teraelectron volts for a starship crew traveling at 99.999998 percent of the speed of light. That's as much fun for humans as standing in front of the proton beam created by the Large Hadron Collider, according to William Edelstein, a physicist at Johns Hopkins University. Read more »

Breakthrough Danish Enzymes to Lower Biofuel Price Point To Petroleum Levels

Coming Soon: A Radiant Cooker That Can Deep-Fry Foods Without Oil

Popular Science - February 17, 2010 - 4:59am

An oil-free deep fryer, which its inventor hopes could hit the market later this year, could let health-conscious consumers have their donuts and eat them, too.

Call it an infrared-wave, radiant fryer, or miracle oven -- it makes french fries with half the fat, no engineered chemicals like Olestra, and the same crispy, oily goodness we all know and love.

The radiant fryer, developed at Purdue University by food scientist Kevin Keener, is meant for foods with just a little bit of oil on them already, like the par-cooked chicken nuggets, hash browns and french fries you'd find at a fast-food restaurant. And that's the target, Keener said.

"You can dial in (a heat level) for a certain product. That would allow a restaurateur to provide on-demand products," he said. "You'd pay your money, and within two minutes, your order is coming out of the fryer hot onto the bun and they are putting it on your plate." Read more »

This could be the year that baseball-stat freaks finally crack the "Derek Jeter enigma." A panel of coaches has awarded the New York Yankees' shortstop four of the past six Gold Glove awards for fielding excellence. That drives statisticians nuts, because nearly every statistical model ranks Jeter's defense below average.

Photoluminescent nanofibers emit light efficiently

For those who want to start saving the planet at home, lighting presents a vexing paradox. While incandescent bulbs are wildly inefficient, compact fluorescent bulbs contain hazardous chemicals. With funding from the Department of Energy, RTI International claims to have solved the problem with the invention of nanofiber bulbs more efficient than regular lights, and more environmentally sound than fluorescent bulbs.

The nanofibers themselves have diameters smaller than a human hair, and emit warm, white light when in contact with an electric current. More important from an energy usage perspective, the nanofiber lights put out 55 lumens of light per watt. That makes them five times more efficient than a traditional light bulb. Read more »

The difficulty of supplying remote outposts across rugged terrain has contributed to many of the deadliest moments in the Afghan War, by preventing the delivery of weapons and ammo to engaged soldiers, forcing supplies to travel over dangerous roads, or turning helicopters into vulnerable targets. Last June, the Marines put out a call for a helicopter UAV to solve those problems. Now, with a successful demonstration at Utah's Dugway Proving Grounds, the Marines might have found their robocopter.

In the demonstration, a modified K-MAX helicopter moved 3,000 pounds across 600 miles, in under six hours.

New Armored Wall System Assembles Like Legos, Could Replace Sandbags in Afghanistan

Popular Science - February 9, 2010 - 9:00am

Attention recruits. Those of you landing in Afghanistan in coming months may not have to engage in the sandbag stacking and trench digging usually associated with lowly grunt-dom. An $800,000 investment in an armored wall system known as McCurdy's Armor could have Marines rapidly erecting 6.5-foot-tall mortar-, RPG- and bullet proof fortresses in less than an hour, saving the days it can take to fortify an area by conventional means and making forward-operating units more nimble.

Named for Ryan S. McCurdy-a Marine killed in Iraq in 2006 while hauling a wounded comrade to safety-the system is designed to offer troops increased protection and mobility when setting up outposts in hostile areas. The walls can be ferried into place in panels that are easily stackable in a truck or trailer. Once in position, four Marines can assemble a single panel in less than ten minutes without any special tools or additional equipment.

By Stimulating Stem Cells, Bioactive Nanogel Regenerates Cartilage in Joints

Popular Science - February 9, 2010 - 7:24am

The body is a resilient biological structure, but there's one thing medical science, an increasing number of Baby Boomers, and the majority of professional athletes will all tell you: Take care of your joints, because once you burn up the cartilage you started with, you're not getting any more. But a breakthrough by Northwestern University scientists will now allow adult joints to naturally grow new cartilage for the very first time.

Unlike bone, muscle and other tissues in the body, cartilage that is damaged or worn away over time does not regenerate itself. The cartilage you have when you reach adulthood has to last you for life; if it doesn't, you can suffer debilitating joint pain or even osteoarthiritis, which is neither pleasant nor effectively treatable.

Popular Science - February 9, 2010 - 3:43am

Come on, you apes! You wanna live forever?

Humanity's search for the secrets to immortality has inspired Ray Kurzweil's Singularity vision and DARPA's hunt for ageless synthetic beings. Now scientists have discovered a single gene that appears to control how quickly individuals will biologically age, The Telegraph reports. The discovery could not only encourage people to adopt healthier lifestyles earlier, but may eventually help people live longer if scientists can figure out how to manipulate the gene. Read more »

Gray Matter: Batteries Out of Thin Air

Popular Science - February 9, 2010 - 2:20am

A little oxygen is all a zinc-air battery needs to become a powerhouse

A battery that runs on air? Why, that's almost as good as a car that runs on water! Those cars are fantasy, but batteries that run on air are actually quite common, especially among older people. Tiny zinc-air batteries are widely used in hearing aids, where they have replaced toxic mercury-based batteries in providing a small but steady stream of power. They supply more energy for their size than any other battery, because they draw some of their power straight from the air.

All batteries generate power with two chemical reactions: one that produces electrons at the anode (negative terminal) and one that absorbs them at the cathode (positive terminal). This creates a circulation of electrons-an electrical current-from the anode to the cathode. Most batteries contain all the chemicals needed for both reactions. Read more »

IBM Demonstrates 100GHz Graphene-Based Transistors

Popular Science - February 6, 2010 - 9:11am

A glimpse of the post-silicon age; how does Graphene Valley sound to you?

Silicon Valley may want to update its name, because IBM has created graphene transistors that blow away the silicon competition. The transistor prototypes were made from sheets of carbon just one atom thick that could switch on and off at 100 billion times per second. The 100-gigahertz speed is about 10 times faster than any silicon equivalents, Technology Review reports.

The transistor creation is supposedly compatible with existing semiconductor manufacturing, and so experts anticipate a scaling-up process that could put transistors into high-performance imaging devices, radar and communication gadgets within the next few years. Graphene-based computer processors might take another decade at least. Read more »

Which Organs Can I Live Without, and How Much Cash Can I Get for Them?

Popular Science - February 6, 2010 - 7:04am

First, a disclaimer: Selling your organs is illegal in the United States. It's also very dangerous. Handing off an organ is risky enough when done in a top hospital, even more so if you're doing it for cash in a back alley. No, really: Don't do this. OK? OK. Read more »

Gene Therapy Is Inevitable Next Frontier for Sports Doping

Popular Science - February 6, 2010 - 3:31am

Dreams of Olympic glory could make athletes risk their lives on an experimental procedure

Steroids seem so last-decade, now that gene therapy has caught the eye of athletes looking for a competitive edge. But scientists warn that gene therapy still represents a high-risk, experimental practice even within medicine, and that athletes could endanger their lives by giving it a try.

Gene therapy has shown promise in a few treatments by helping swap out defective genes or changing the degree to which genes turn on and off. For instance, it has helped establish some immune system function in so-called "bubble children." But researchers have become extra cautious with gene therapy ever since the death of 18-year-old Jesse Gelsinger during a 1999 research trial. Read more »
