There are certain unnamed Cravers who, we're told, can sit and stare for hours on end at fake stars and planets projected on the wall. And yet there are others who actually enjoy viewing the heavens in reality outside (gasp). For those brave souls, there are several handheld scopes and personal planeteriums that can help navigate the night sky, including some in alien form.
There's no end to scams on the Internet, and it can be hard for anyone to tell the difference between a legitimate and fake Web address. (Can you pick the bogus URL between "www.express.ebay.com" and "www.ebaysale.nl"?)
That's why computer scientists at Carnegie Mellon University developed a cutesy online game to teach people how to spot a so-called phishing scam before giving up personal information like bank account passwords to a rogue operator. The 15-minute game, called Anti-Phishing Phil, features a little fish named Phil that must discern between good … Read more
Like its diminutive avian namesake, Boeing's A160T Hummingbird is a whiz at hovering. And it turns out the prototype aircraft can also hoist a hefty load.
The unmanned helicopter this week flew for eight hours--its longest flight to date--and as high as 5,000 feet while burdened with a 1,000-pound payload. The test flight goes a long way toward proving the Hummingbird fit for use in military operations, where it could ferry supplies, sensors or weapons to the battlefield, perform surveillance and target acquisition, or even rescue pilots who've been shot down.
Over time, Boeing wants to … Read more
Richard Garriott, a game developer known for creating the multiplayer online game Ultima, will be the sixth private citizen to take a ride on a Russian Soyuz rocket to the International Space Station in October 2008. And in a way, he will follow in his father's footsteps, but without the NASA credentials. Garriott's dad is former NASA astronaut Owen Garriott, who flew to the first U.S. space station Skylab in the '70s.
Garriott will fly with Vienna, Va.-based Space Adventures, a space tourism company that offers flights to ISS for between $25 million and $30 million. … Read more
If you live in Kansas, the Japanese obsession with earthquake-detection devices might seem a bit insane. But we can guarantee they'll be of interest to anyone from California or other parts of the world where fault lines run free.
Usually, the gadgets we've seen claim to give some kind of early warning--and are therefore of dubious value. The unpronounceable "GraGraph," however, seems more realistic: It supposedly indicates the Richter-scale strength of a temblor as it's occurring in real time, according to SCI FI Tech. That's something people might actually buy, as evidenced by … Read more
Medical instrument sterilization is a hot, dirty, expensive business involving chemicals, ozone-depleting aerosols and hazardous waste, but a new plasma technology promises to change the way we kill germs.
Atmospheric Glow Technologies of Knoxville, Tenn., is building a portable medical device called the Steriglow Sterilization System that it says will produce no waste or heat and costs much less to operate than existing technologies.
The process takes plasma, the same stuff found in flat-screen TVs, and creates "short-lived reactive chemical species from air" that neutralizes all biocontaminants. Viruses, bacteria, fungi--it kills them all. It's so effective that … Read more
Researchers at Rensselaer Polytechnic Institute have come up with a way to detect potential structural problems with fighter planes while in flight, and in some cases repair them.
The technique, which is still experimental, involves applying an epoxy later infused with a wire grid and carbon nanotubes onto a wing or other structure. The epoxy is similar to the materials currently used to make fighter plane components. The wire grid and the nanotubes function as a communication network. Mechanics (or a computer) will shoot an electrical charge through the structure and measure how long it takes an electrical charge to … Read more
You've probably seen or heard of the industrial robots that build cars, and the various humanoid robots like Honda's Asimo. Most of these are made in Japan. But let's face it, there's only so much these can do. An industrial robot is bolted down, and only knows one or two simple tasks. Asimo is small and weak, and famously collapsed once while trying to climb stairs.
As we know from sci-fi movies, real robots are the size of a man and can do things--dangerous things. Real robots are suitable for building robot armies. For that, we … Read more
A bug in Excel 2007 reported earlier this week may be ugly, but it's only skin deep, Microsoft said late Tuesday.
With the bug, results that should have been shown as 65,535 showed instead as 100,000, and a related problem cropped up with 65,536, Microsoft's David Gainer said in a blog posting. But the problem affected how Excel showed the number, not in what the spreadsheet software actually "knows."
"This is an issue in a function that puts numbers in cells, so the values in Excel's memory are actually correct," … Read more
Believe it or not, one of the most popular items ever featured on Crave was a hand dryer. Not just any old washroom appliance, mind you, but the Dyson Airblade--a supposedly state-of-the-art contraption from the U.K. that "strips water droplets off your mitts in 6 to 12 seconds" with air traveling at 400 miles per hour. (See NYC Craver Rich DeMuro test it out in this video and judge for yourself.)
