Creepy Two-Legged Robot Walks Like a Human

It's not going to win any foot races, but a new robot being developed for the U.S. Army still has a leg (or two) up on its competition. The "Petman" prototype is a bipedal robot that simulates human walking (video after the break) more realistically than any other robot we've seen. According to Wired, the robot, which is being developed by Boston Dynamics, will be used to test how protective clothing responds during chemical warfare. It walks with a heel-to-toe motion at 3.2 mph and can maintain balance if pushed or bumped. Plus, the robot simulates human environmental and physiological factors -- like temperature, humidity, and "sweating" -- to provide even more realistic testing conditions.

There's a slew of walking robots out there, but "Petman" stands out in the crowd. It's hard to pinpoint what's most amazing -- the 'bot's balance or the walking motion. Just as long as the Army is really using "Petman" to test clothing, and creating a plethora of robot super soldiers. [From: Wired]

Thumbnail-Sized Chip Holds Equivalent of 20 HD DVDs


Engineers at North Carolina State University have created a computer chip that holds one terabyte -- or 1,000 gigabytes -- of data and is no larger than a fingernail. For perspective, that means you could store 20 high-definition DVDs or 250 million pages of text on this tiny chip. According to Computer World, this modern marvel is made possible by a process called selective doping, in which engineers add an impurity to a material in order to change its properties. In this case, it results in a drastic reduction in size.

Not only does this breakthrough affect data storage, but it has implications for 'green' technology, too. For example, engineers could use selective doping to build ceramic engines that could withstand higher temperatures. That possible outcome, lead engineer Jagdish "Jay" Narayan says, could lead to better fuel efficiency. Doping could also better solar energy by improving the thermal conductivity of the materials used.

Disney's 'Sum of All Thrills' Ride Lets Kids Use Math Skills


Thanks to those imagineers at Walt Disney World, you no longer have to be an engineer to design a theme park ride, or be a nerd to have fun doing math. A new interactive feature, developed by Disney and military contractor Raytheon, and called Sum of All Thrills, opened yesterday at Disney's Epcot park. Both of the parties involved hope it'll teach kids that engineering and math can be fun and useful.

According to The New York Times, visitors to the exhibit use a touchscreen to design a roller coaster, bobsled, or jet ride. While you add head-spinning corkscrews and stomach-churning drops via onscreen tools like rulers and dials, mathematical formulas for velocity and acceleration appear on the screen. When your dream ride is complete, you can even hop into a robotic simulator to experience your custom creation.

NASA Creating Meals for Mars Mission to Last Five Years

Eating five-year-old food doesn't sound too appetizing to us. But to the astronauts that NASA will eventually send to Mars, it'll taste as good as any five-star restaurant's fare. Well, maybe not that good, but it will be the sole sustenance for that group of men and women during their grueling trip into outer space.

According to the Los Angeles Times, NASA will need to pack enough food to feed six people every day for three years. That's about 6,750 breakfasts, lunches, snacks, and dinners. The toughest part is making sure the food doesn't spoil. NASA engineers are searching for different preservation methods and menus for the trip, which would last years. Their plan will most likely involve sending food to Mars ahead of the astronauts.

Nerds Program Videogame Bots to Wage Nuclear War

What happens when you take one large group of nerds, throw them in a convention, and tell them to cut loose? Well, we'll give you a hint: it doesn't involve boatloads of booze, loud music, or a conga line.

The Institute of Electrical and Electronics Engineers challenged the attendants of its convention to create a big, bad bot to ultimately win a one-on-one tournament in DEFCON -- a strategy game that Fidgit calls a "thermonuclear chess match." Essentially, the programmers try to convince judges that the artificial intelligence is a person playing the game.The person whose AI bot racks up the most kills wins $500 and a legion of nerdy fans.

Web Sites Every Science Geek Should Know

If you've ever had a question about hierarchical multiple regression or parametric graphs and didn't know where to turn, we've got a bookmark-worthy Web page just for you. Mary Spiro of The Examiner has compiled the 'Top 20 Web Sites Every Scientist (or Engineer) Ought to Know,' a list intended for science geeks, engineer brainiacs, or just curious nerds-to-be.

The list has a little bit for everyone, including a free statistics calculator, a database of over 750,000 science acronyms and their meanings, lists of thousands of current scientific press releases, as well as lighthearted entries such as ScienceHumor.org. You'll also find sites that can help the budding scientist receive grants or figure out if their latest invention infringes on someone else's patent.

The list is outstanding, but is sadly missing two of our favorite science-related sites. The MadSci Network gives students and the scientifically curious a "collective cranium of scientists providing answers" to their questions. And, even though it may not provide any groundbreaking theories or equations, DorkYearbook.com traces the evolution of technology and trendy geek couture through a huge and hilarious database of pictures.

Spiro does say the list is "by no means comprehensive," so use the comments section below to let us know where you get your daily science fix. [From: Examiner.com]

Heart Beats Outside Body With Help of Machine


Featuring a setup made of pipes and rods running in and out of a still-beating heart, a lab at North Carolina State University (NCSU) could be mistaken for that of a mad scientist. Researchers there have recently created a computer-controlled machine that can keep a heart beating outside the body, according to NCSU's Web site.

Researchers said they plan to use the machine (designed by NCSU mechanical engineering students) in conjunction with internal cameras so that they might be able to determine the best way to repair heart valves. Don't worry; researchers aren't using human hearts just yet. A local pork processing facility donates pig hearts for the betterment of medicine and science.

We hope this engineering marvel will help lead to some truly amazing medical breakthroughs. That said, we can't help feeling a little odd while watching the video. After all, the closest we have come to seeing a heart beat outside a body was when we watched 'Indiana Jones and the Temple of Doom.' [From: NCSU, via Neatorama]
