Earthquake-resistant bed can withstand 65 tons of falling debris

By Bridget Borgobello

Following the lead of the Earthquake-proof school desk, Wood Luck is an earthquake resistant bed that can withstand up to 65 short tons (59 metric tonnes) of falling debris. Designed by Shinko Industries, the bed has been built to give users some “good luck” protection during an earthquake. And with the ability to withstand 65 tons of tumbling detritus, it may just become a lifesaving piece of furniture during an emergency situation.

Make this Electrostatic Motor From Scrap


   Here is an electrostatic motor that' s easily built for a science project. The rotor was constructed by laminating a strip of aluminum foil between layers of plastic packaging tape and rolling it into a tube. The tube was mounted on an axle using cardboard end caps w/flat washers at the centers as bearings. Stationary electrodes or stators were made from a ring of nails suspended co-axially w/respect to the rotor and energized w/negative, high voltage DC. A framework made from drinking straws, tape and plastic covers of tin cans maintained the stators in proper alignment around the rotor.

Mind-reading exoskeleton could help rehabilitate stroke victims

A collaboration between Rice University, the University of Houston and TIRR Memorial Hermann Hospital has led to MAHI-EXO II, a sophisticated exoskeleton that could help stroke victims regain movement in the arms by reading the patients' intended actions and nudging them along when needed. The robot wraps the arm from the fingertips to the elbow and uses a non-invasive EEG interface to anticipate gestures and help patients build up strength and accuracy over time.
When the subject thinks about performing an action, an electrode-studded cap reads the electrical impulses from the motor cortex of the brain and then outputs them to the artificial limb, initiating motion with a simple thought.
