MIT's robo-fish swims like the real thing
00:23 October 9, 2009 PDT
What is it with scientists and robotic animals? Did they not have pets as children? This year alone, we’ve seen robot ferrets, penguins, dogs, locusts, moles and bats. And now, scientists at MIT have come up with a robotic fish. Although we’ve seen mechanical fish before, this one is different in a very significant way – the robofish truly mimics the natural swimming action of real fish, flexing mechanical muscles to propel itself through the water.

Pentagon looking for someone to pick up the trash in space
18:05 October 8, 2009 PDT
The Soviet Union launched the very first earth-orbiting satellite in 1957, and the world looked on in awe as Sputnik flashed through the sky. Fifty years later, you’d be lucky to see anything. The U.S. Space Surveillance Network says there are almost 20,000 man-made objects in orbit, ninety-four percent of which are non-functional debris. And that’s not counting the hundreds of thousands of bits of junk too small to track. Little wonder the Defense Advanced Research Projects Agency (DARPA) has put out a call for someone – anyone – to come up with a way to effectively remove orbital debris. Read More
British Steam team achieves dream: smashes two world speed records
02:39 September 15, 2009 PDT
Last month, we reported that the British Steam Car had its sights set on several long-standing world records – and we’re happy to report that they’ve smashed not one, but two in the last week of August at Edwards Air Force Base in California. On Tuesday, August 25, they broke the world’s longest-standing speed record with a 139.843mph measured mile and then, the next day, clobbered the record for a measured kilometer with a speed of 148.308mph.

Boeing Airborne Laser ‘shoots down’ first missile
20:19 August 23, 2009 PDT
On August 10, Boeing and the U.S. Missile Defense Agency were finally able to demonstrate that the US$1.1 billion Airborne Laser (ABL) program actually works. The ABL aircraft, a modified Boeing 747-400, took off from Edwards Air Force Base and located, tracked and fired on a target missile. Although a surrogate high-energy laser was used – rather than the megawatt-class laser that will ultimately arm it – instrumentation on the target verified the hit. Read More
Wireless pacemaker talks to cardiac specialist via Internet
23:53 August 19, 2009 PDT
The world’s very first fully implanted pacemaker, in 1958, lasted three hours before the batteries failed. It was replaced by one that lasted two days. Ultimately, Arne Larsson – surgical guinea pig – went on to receive 26 different pacemakers over the next 43 years. Now, a New York woman has become the first person in the world to receive a pacemaker that allows completely wireless monitoring, transmitting clinical data to her doctor each day via the Internet. And, if anything ever goes wrong, the doctor is alerted instantly. Read More
SanDisk slotRadio – a thousand songs for 10¢ each, player included
19:22 August 18, 2009 PDT
As flash memory card capacity increases exponentially and prices fall equally fast, manufacturers are looking for new ways to innovate. SanDisk, one of the world’s biggest makers of memory products, has partnered with the Billboard charts in order to compete with music players like the iPod. The SanDisk slotRadio is a small, stylish player that comes bundled with a micro SD flash card pre-loaded with 1000 chart-topping songs for just USD$99.99. It’s certainly great value, but the big drawback is the music won’t play on anything else. Read More
Full steam ahead! British Steam Car hits 131mph
21:18 August 16, 2009 PDT
There’s something endearingly quixotic – and awfully English – about the British Steam Car Challenge. The team has spent the last ten years trying to successfully marry Victorian-age transport with modern technology in an effort break a 100-year-old steam land speed record. And, on Friday August 7 at Edwards Air Force base in California, they finally beat that world record speed with a run of 131mph – but because the FIA wasn’t present, it’s not yet official. Read More
Video games finally pay off: Air Force needs more virtual flyers than real pilots
02:39 August 14, 2009 PDT
There was once a great Far Side cartoon that had ‘hopeful parents’ imagining a newspaper full of Help Wanted ads for skilled video game players. Well, it looks like Gary Larson might have been more prescient than he imagined. The US Air Force has just revealed that, this year, it will train more ‘pilots’ to remotely operate unmanned aircraft than pilots to fly fighters and bombers. Read More
Nature can still surprise us: more than 350 new species found in Himalayas
16:53 August 13, 2009 PDT
You’d think there’d be nothing new in the world to discover, but Mother Nature still has a few surprises up her sleeve. According to a new report from the World Wildlife Fund (WWF), scientists have discovered 353 new species in the eastern Himalayas over the past decade. They include a ‘flying frog’ that glides using long webbed feet, fossil evidence of a 100 million-year-old gecko, and the world’s shortest deer which, when fully grown, stands just 20 inches tall.

Painting brain tumors with nanoparticles may help defeat cancer
22:52 August 12, 2009 PDT
Nanotechnology is preoccupying science to the point where it's starting to seem unremarkable. But a group of researchers from the University of Washington has released findings that could profoundly improve the chances of surviving brain cancer. The team has developed a fluorescent nanoparticle that is capable of penetrating – for the first time – the blood-brain barrier without damaging it. The fluoro nanoparticle targets tumors using a derivative of scorpion venom and enables precise imaging of the size and location of cancerous growths. When the particles meet the tumor, they light up like Christmas. Read More
Diesel used as gasoline 'spark plug' improves economy and emissions
23:18 August 11, 2009 PDT
The two engine technologies tend to be regarded as completely separate, so we rarely contemplate how gasoline and diesel can work together. But, in a series of tests conducted at the University of Wisconsin, scientists have used an engine’s fuel injection to produce the optimal diesel-gas mix for any given moment. The results are impressive: an average 20% greater fuel efficiency; combustion temperatures reduced by up to 40%; and effortless meeting of the stringent EPA 2010 emission regulations. Plus, the researchers believe that if their findings were implemented into every gasoline and diesel engine in the US, the savings could be as great as 4 million barrels of oil daily. Read More
Harnessing blowflies to teach robots how to see
19:24 August 11, 2009 PDT
One of the biggest challenges facing robotics is teaching machines to perceive surroundings and make sense of what they see. Attempting to duplicate the complexity of human perception is next to impossible, so researchers at Cognition for Technical Systems (CoTeSys) in Munich are, instead, studying how blowflies process images using a 'flight simulator'. Despite having a brain the size of a pinhead, a fly can process and interpret 100 discrete images per second – four times better than humans. Read More
Is this the world’s best ship design? The Austal 102 trimaran
22:30 August 6, 2009 PDT
Shipbuilder Austal first came to Gizmag’s attention in 2005 with the launch of the world’s largest aluminum vessel, the 127 meter Benchijigua Express. The company then started building Littoral Combat Ships (LCS) for the US Navy, based on the same trimaran design. And, now, Austal is launching an even more refined version that improves sea-keeping, passenger comfort and fuel efficiency. This week, Tony Armstrong, Austal’s head of R&D, spoke exclusively to Gizmag about potentially building 20% of the US Navy fleet, how they reduced fuel consumption by a quarter, what sick bags can tell you, and much more.

MIT tackles challenge of electric car that recharges in ten minutes flat
00:53 August 6, 2009 PDT
Sometimes in science, it helps to set the bar high. That seems to be the attitude of the MIT Electric Vehicle Team (EVT). By their reckoning, one of the biggest impediments to the average driver adopting an electric vehicle is recharge times. So, having converted a Porsche 914 to electric, their next project is to produce a prototype family car that will achieve 0-60mph in under nine seconds, have a range of 200 miles, and fully recharge in under 11 minutes.

From AAA to D: the one-size-fits-all rechargeable battery concept
16:52 August 3, 2009 PDT
People think deeply about everything, even batteries. Comedian Demetri Martin, for example, decided the reason there’s no B-Battery is because it’d sound like you had a stutter asking for one. A group of Korean designers, on the other hand, has decided what the world really needs is a rechargeable nickel hydroxide battery that, thanks to a memory foam casing, can squeeze down to fit any size from AAA to D.

U.S. vehicle fuel efficiency has increased only 3 mpg in 80 years
23:50 August 2, 2009 PDT
Gizmag is always on the lookout for alternative means of powering vehicles and saving precious fossil fuels. But, in truth, the vast majority of us still drive exclusively petrol-powered cars. And the even sadder truth, outlined in a new research from the University of Michigan, is that the average fuel efficiency of a US vehicle has improved only three miles per gallon since the days of the Ford Model T.

New barcode system could see the end of ugly stripes
20:03 August 2, 2009 PDT
I remember encountering the ugly black-and-white stripes of a barcode for the first time – defacing the front of my favorite magazine. Of course, Mad found a way of dealing with the UPC code by making jokes at its expense. But now, some ground-breaking work at MIT could see the visual blight of barcodes replaced altogether by Bokodes, tiny tenth-of-an-inch optical data tags that can hold thousands of times more information and be read by the camera on your mobile phone.

Virgin Galactic mothership debuts at AirVenture
07:38 July 29, 2009 PDT
If Richard Branson turns up somewhere, you can be fairly certain there’ll be a photo opportunity attached. But Branson’s appearance on Monday at EAA Airventure, the world’s largest private air show, was much more than a PR stunt. It also marked the first public flight of Virgin Galactic’s “Mothership” Eve, and signaled space tourism is now closer than ever. Read More
Smart concept for public transport solar ‘bike’ - but can the public be trusted?
23:05 July 28, 2009 PDT
Young German industrial designer, Tobias Bexten, has come up with a nifty little idea for city transport. The STEM is a compact electric three-wheeler, powered by a lithium-ion battery, that would be available for pick-up and return at a city-wide infrastructure of rental stations. But, if a popular Parisian bike rental scheme is anything to go by, Tobias could expect to see half his bikes stolen, and the rest vandalized, hung from lamp posts and tossed in rivers. Read More
New ion engine could reach Mars in 39 days
18:41 July 28, 2009 PDT
Last week, as the world celebrated the first lunar landing, Apollo 11 astronauts Buzz Aldrin and Michael Collins both called for NASA to make Mars its next goal. But the chemical propulsion system that took them to the moon would take six months, at least, to get a man to Mars and cost hundreds of billions of dollars. However, a new ion plasma rocket being developed by another former astronaut, Franklin Chang-Diaz, could potentially reach Mars in just 39 days using a fraction of the fuel. Read More
Powerbocking: jump like a kangaroo, run like a gazelle & stride like a giant
06:46 July 27, 2009 PDT
They’re enough to fulfill anyone’s dreams of bionic powers: jump six feet in the air (and over cars, if you’re in the mood), run at 25 miles an hour or more, and stride nine feet at a time. But, instead of costing Six Million Dollars, you can invest in a pair of “powerbocks” for just a couple of hundred. A cross between stilts and a pogo stick that harnesses energy in the same way as a trampoline, a set of Powerbocks will not only make you part of a sport that can help you lose weight, build strength and reduce cholesterol, but you’ll also be drawn into a craze that’s swept the world from Korea to Canada.

South African bank arms ATMs with pepper spray, blinds employees
23:24 July 26, 2009 PDT
Who’d want to work for a bank in South Africa? If violent attacks on ATMs weren’t enough – more than 500 were bombed last year – then the ATMs themselves start turning on you. In a desperate attempt to stem the growing tide of crime, Absa Bank fitted pepper spray to 11 cash machines in Western Cape, a popular tourist area. But, so far, the spray has only prevented three maintenance workers from doing their jobs. Read More
New software ensures no-one will ever read over your shoulder again
19:14 July 23, 2009 PDT
We need a name to describe that sensation you often get, in an office or out in public, that someone’s looking at your computer screen from behind you. Screen-dropping? Shoulder-surfing? Whatever it’s called, it’s annoying – and a potential security threat. Baltimore company Oculis, has developed a program that tracks an authorized reader's eyes to show only them the correct text. Anyone else looking at the screen will see only gobbledygook Read More
Physicists find way to hide buildings from earthquakes
23:41 July 21, 2009 PDT
According to the U.S. Geological Survey, there are 500,000 detectable earthquakes every year, of which 100,000 will be felt and about 100 will cause damage. Engineers now use seismic vibration control technology - and base isolation in particular – to make buildings more earthquake-proof. But what about existing structures? Researchers from the University of Liverpool have now developed a means of effectively making buildings “invisible” to the destructive path of a quake. Read More
K-box turns anything flat into a giant speaker
18:57 July 21, 2009 PDT
As personal music players like the iPod become ubiquitous, there’s another developing trend that’s even more insidious: the desire to share that music with everyone else. Miini speakers are flooding the market at the moment, but a new product called the Kerchoonz K-box promises to make even more noise. A compact, mobile-phone sized device, the K-box turns any flat surface – wall, table, window, ceiling – into a giant speaker. Read More
