Urea In Astronaut Pee Could Be Used To Build Moon Bases

science20.com – I'm not all that excited about manned missions in space because it is a struggle for NASA to even build a space telescope without going 13 years over budget, but it's worth doing basic research on how an outpost on Luna might be built.It will require a lot of multi-purposing, and re-purposing.

Engineers test a powered 'ankle exoskeleton' to make running easier

engadget.com – Ankle exoskeletons could help you run longer and faster and even serve as a new mode of transportation, according to a team of Stanford University engineers. The engineers tested a motorized exoskeleton rig that attaches around the ankle and foot and found that it made running 15 percent easier. They explained that when the exoskeleton's motor is switched on, it reduces the energy cost of running and allows the user to run longer than they're usually capable of. The device can also boost a...
