Exoskeletons are valuable for several reasons — they can help military personnel carry a heavier load, and they can be used all in the name of fun. But this one might be the best use of all: A 22-year-old paraplegic college graduate, paralyzed since a 2007 car crash, used an exoskeleton to walk across the stage Saturday to receive his diploma.
NASA's youngest space shuttle left Earth for the last time Monday, carrying a physics experiment and spare parts to the International Space Station. It was a bittersweet moment for shuttle followers who watched the shuttle's picture-perfect liftoff with the knowledge that there's only one of these left.
Commander Mark Kelly had some poignant words in the moments before ignition.
The slightest whisper of warmth induces miscalculations in the world’s most precise atomic clock, researchers say. Accounting for this effect can make future clocks even more precise, eventually leading to atomic clocks that lose only one second every 32 billion years — about two and a half times the age of the universe itself.
One cell is all it takes to rebuild a complete, functioning flatworm, researchers have learned. The animals possess a special type of cell throughout their bodies, which shares some qualities with human embryonic stem cells. If scientists can find out how this special cell works, they could someday study ways to use the cells for human tissue regeneration.
The findings are the first time pluripotent stem cells have been found in an adult animal, according to researchers at MIT and the Howard Hughes Medical Institute.
Diamonds are the hardest solid materials we know, and the ghostly space-age materials known as aerogels are the least dense. Looking for a challenge, scientists at Lawrence Livermore National Laboratory decided to combine these substances and turn out a spongy, translucent version of a girl’s best friend.
Our current president is a proud nerd, appearing on shows like Mythbusters, collecting comic books in his youth and dropping references to dilithium crystals (really). But the most prominent Republican to challenge him so far is also a science dork, judging from his Amazon book reviews.
The robotics engineers at DLR, the German Aerospace Center, have a history of violent behavior with their mechanical creations — earlier this year, we saw them smash a robot's hand with a hammer, and last year we watched brave engineers give a robot a knife and let themselves be stabbed.
Foodies want to know everything about their animal-based dishes these days — where the meat came from, what it ate, what its name was. OK, maybe not that last part. But there is a big difference between industrial cattle farms and grass-fed meat — both in price and in nutritional considerations.
Labs-on-a-chip are useful tools for diagnosing diseases, but most can only pick out one or two sickness signatures amid an array of symptoms. The X Prize Foundation, responsible for innovation challenges in anything from spacecraft to oil spills, wants an all-purpose mobile device that can diagnose a patient better than a doctor. A tricorder!
