morto writes: "The Strong Goldbach conjecture dates back to 1742. It states that every even integer greater than four can be written as the sum of two prime numbers. Since then, no one has been able to prove the conjecture....Additionally, the conjecture has been verified to be true for all even integers up to 4.10^18. In this paper, we prove that the conjecture is true for all even integers greater than 362."

Harvard's Whitesides Research Group is working on a soft-bodied solution and has produced a squishy three-legged bot that can jump 30 times its height using the power of internal explosions. Embedded pneumatic networks in the robot – channels that course like veins throughout the robot's elastomer body – were fed a mixture of oxygen and methane which – when ignited with an electrical spark – results in an explosion that sends the robot flying into the air. By actuating all three legs simultaneously the team succeeded in getting the robot to leap more than 30 times its height.
