US Navy drone flies two days straight using liquid hydrogen tank
Author: Stefanie Jenkins
As the US military discovers just how useful drones can be, it’s eager to keep them flying as long as can be, and the US Office of Naval Research now has a drone that can fly for two whole days. The Ion Tiger, an experimental surveillance plane that uses a hydrogen fuel cell as its power source, flew for a record 26 hours using pressurized hydrogen back in 2009, but late last month it managed a full 48 hours and one minute thanks to a new cryogenic storage tank filled with liquid hydrogen. That’s not the only way to keep lightweight aircraft flying for lengthy periods, as laser beams and solar panels have recently shown, but the hydrogen could allow planes to fly further afield and at more flexible hours of the day than the other…

How can you copy and paste Strings in Java using the Robot class?
Author: Jenny Zhao
Question by infinite zero: How can you copy and paste Strings in Java using the Robot class?
The Java Robot class has functions to type individual letters, but say you wanted a whole string to be written. How would you do that?
Best answer:
Answer by Patrick
my best solution is to iterate through the String and use the Robot class per character.
The code that comes to mind is:
String str = “whatever”
for(int i = 0; i < str.length(); i++)
{
robot.keyPress(str.charAt(i));
robot.keyRelease(str.charAt(i));
}
I bet there is a slightly better way to make the loop, but it escapes my mind at the moment... like:
for (char c : str.toCharArray())
{
robot.keyPress(c);
robot.keyRelease(c);
}
This one, gets the char array, and uses a modified for loop to iterate the characters. Same idea, but better code. How does that work?

Teensy: Stop Motion Made Using Single Atoms As Pixels
Author: Brian McKinnell
This is a short stop motion video from IBM that they produced using SINGLE ATOMS as individual pixels. Do you understand how small an atom is? No? Well think of a bouncy ball. Now think of a SUPER F \*\*\* ING TEENY bouncy ball. That’s how small an atom is provided you imagined a bouncy ball small enough. The atoms in the video have actually been multiplied 100-million times. The pubic hair I plucked and looked at under a microscope in 10th grade biology course? I think that was 50x. My laboratory partner informed on me too which is exactly why she got SHOCK DISSECTED FROG COMPONENTS in her knapsack the following semester. Do not tinker science, Stephanie!
Arrived the jump for the short in addition to a making-of video if you’re really into science and not simply fabricating it due to the fact that science is supposed to be so cool right now. You know who you are.

Dances with atoms: IBM researchers create a short film using only microscopic particles
Author: Stefanie Jenkins
A group of IBM researchers took a break from studying atomic data storage to work on something a bit more lighthearted: a stop motion movie made entirely out of atoms. The film, aptly named A Boy and His Atom, was created by arranging atoms with a scanning tunneling microscope and then capturing the arrangement as an image, magnified to over 100 million times its actual size. The final result is a brief 242 frames that show a charming story of a boy dancing and playing with an atom. Before its debut today, IBM even had the Guinness World Records verify the short as the “world’s smallest movie.”
IBM is accompanying the film with a series of short videos explaining the technology that was involved in creating it. In the videos, the team…

No Comments »Extreme closeup! IBM makes ‘world’s smallest movie’ using atoms (video)
Author: Ian Simpson
After taking a few shadowy pictures for the scientific world’s paparazzi, the atom is now ready for its closeup. Today, a team of IBM scientists are bypassing the big screen to unveil what they call the “world’s smallest movie.” This atomic motion picture was created with the help of a two-ton IBM-made microscope that operates at a bone-chilling negative 268 degrees Celsius. This hardware was used to control a probe that pulled and arranged atoms for stop-motion shots used in the 242-frame film. A playful spin on microcomputing, the short was made by the same team of IBM eggheads who recently developed the world’s smallest magnetic bit. Now that the atom’s gone Hollywood, what’s next, a molecular entourage?

‘Eve Online’ developer builds a virtual reality space dogfighting simulation using Oculus Rift
Author: Stefanie Jenkins
If you had any question whether the Oculus Rift virtual reality headset would lead to desirable new games, just ask any of the 1,500 people who attended FanFest 2013 in Iceland this year. There, Eve Online developer CCP showed off “EVR,” a proof-of-concept game, which stuffs players into the virtual cockpits of a 360-degree turn-and-burn multiplayer space dogfighting simulation that appears to be set in the Eve Online universe. If reports from the conference are any indication, attendees who tried the game were extremely impressed.
It looks something like this, if you can imagine this trailer inside the wraparound 3D view of a virtual reality headset:
Presently, the demo uses a standard gamepad to fly around and fire weapons, but the…

No Comments »Run, walk, and jump with the Oculus Rift using Virtuix’s 360-degree treadmill
Author: Angela Stephens
Joysticks could be a thing of the past: Virtuix will soon debut an omni-directional treadmill that can track gamers as they run, walk, and jump in every direction. The device — aptly dubbed the Omni — can be used on its own to replace traditional video game movement controls, or it can be used alongside other virtual reality hardware, including the Oculus Rift, for a more encompassing VR experience. The company has shown off support for games including Crysis Warhead, Team Fortress 2, and Skyrim in a series of YouTube videos, but we’re told that the device will work with all PC games when it’s released.
Virtuix is aiming to launch a Kickstarter campaign for the Omni around the end of May or the beginning of June, and it’s targeting…

Instead of using live animals for entertainment purposes?
Author: Jamie Colby
Question by ☆Bombastic☆: Instead of using live animals for entertainment purposes?
Will we ever be able to use robotics instead?
Most of you know that in the real world bears don’t ride bicycles, tigers don’t have to jump through flaming hoops, elephants don’t do head stands, and shamu doesn’t live in his own personal pool the size of a football field.
I love animals, I love watching them perform – but I am also distrubed by the images I see of the trainers beating them into submission so they perform.
Will we ever be able to go to an animal show that used robotics instead of live, captive animals?
Best answer:
Answer by Young Einstein
I am sure that someday we will be able, but it just won’t be the same. You see, training animals to do things is actually human natur, the way the caveman trained their dogs or wolves to be their friends and aid them in hunting, fishing, etc. So, we do train animals to perform things not because we are cruel and greedy that way, but because it is just in outr nature to do so.
Sincerely,
Young Einstein

Farmer Discovers The Rock He’s Been Using As A Ham Press The Last 30 Years Is Actually A $5-Million Meteorite
Author: Janet Odell
Spanish farmer Faustino Asensio Lopez discovered an unusual 220-lb iron rock while inspecting his fields in 1980. So what did he do? What anybody else would, used it as a ham press to smash meat for the next 30 years. Space hams, bro.
Then in 2011 he saw a TV program about meteor showers in Spain, and wondered if his ham press might have actually come from space.
Now after extensive analysis by geologists, it has been determined that Lopez’s ham press is actually a pre-historic metallic meteorite, with a value somewhere north of $ 5 million.
I wonder if Faustino was happy to discover he was rich, or pissed because he could have been rich 30 years ago. Because I would have been the latter. What can I say, I’m a half glass empty kind of guy. But to my credit, I am double-fisting.
Thanks to Mitch and Pau, who would have used it as a doorstop.
