3D imaging reveals secret fibers that connect tendons to bone
The Achilles tendon is a powerful body part connecting calf muscle to heel bone, enabling springing leaps and hurdles that make sports stars seem superhuman. But exactly how it connects to the bone hasn't been fully understood -- until now. Researchers from multiple disciplines took a microscopic look and found an extremely thin tissue layer that enables the tendon's great expansive strength.
NASA, GM working on a 'Robo-Glove' to assist astronauts and autoworkers alike
We've seen power assist technology designed to help people walk, bike or just tote luggage around, and now we've for the Human Grasp Assist aka Robo-Glove. Under development from GM and NASA, the project takes inspiration from technology designed to give Robonaut 2 a hand capable of using tools designed for humans to embed actuators in the top of the glove that provide additional grip for the hands of meatbags. Once its pressure sensors detect the wearer is picking up a tool the synthetic tendons retract, holding them there until the sensor gives the signal to release. Current prototypes still weigh about two pounds and run off of a belt-mounted lithium-ion battery, although we still find the idea preferable to humanoid replacement like the impervious-to-baseball-bats DLR Hand System. By reducing the amount of force factory workers need to hold a tool from 15 to 20 pounds to just 5 to 10 pounds its expected to cut down the risk of repetitive motion injuries -- we'll wait for the fourth generation model to see what they can do for bloggers or Lee Evans. Until then, check after the break for a press release and quick demonstration video.
Encrypted Text: When your DPS doesn't matter
Every week, WoW Insider brings you Encrypted Text for assassination, combat and subtlety rogues. Chase Christian will be your guide to the world of shadows every Wednesday. Feel free to email me with any questions or article suggestions you'd like to see covered here. Rogues are all about DPS. You've heard my spiel about us being the only pure melee class, which makes DPS the only thing we bring to the table. SportsCenter can claim that Tim Tebow is a great quarterback, in spite of his shortcomings, because of his "intangible" benefits. Rogues don't have that luxury. If you parse poorly, then you get labeled as a bad rogue. I was in the Raid Finder last week, and a warrior from another server tried calling me out for using Cloak of Shadows to stay in during Morchok's Black Blood phase. "Hey, that rogue didn't run out, that's not fair," he complained in raid chat. The last time I checked, all is fair in love, war, and the DPS meters. However, there is one higher calling than DPS, and that is the success of your raid or party. Even though it's against our nature, we occasionally have to sacrifice some of our personal DPS in order to benefit the raid.
