Material Could Enable Cheap Phase-changing Robots

July 15, 2014 7:00 am | by MIT, Helen Knight Videos Comments

In the movie “Terminator 2: Judgment Day,” the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now, a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.

Saturday Marks First ‘Supermoon’ of Summer

July 11, 2014 12:45 pm | by NASA Videos Comments

The full moon on Saturday will appear to be unusually big. In fact, it will be a "supermoon." The moon follows an elliptical path around Earth with one side— perigee— about 50,000 km closer than the other— apogee. Full moons that occur on the perigee side of the moon's orbit seem 14 percent bigger and 30 percent brighter than regular full moons.

Video Brings Arachnid Back from the Dead

July 11, 2014 7:00 am | by The Univ. of Manchester Videos Comments

A stunning video based on fossils of a 410-million-year-old arachnid– one of the first predators on land– recreates the animal walking. Scientists used the fossils– thin slices of rock showing the animal’s cross-section– to work out the range of motion in the limbs of this ancient, extinct early relative of spiders.
