Seventy-five years ago, on 18–19 September 1941, the Earth experienced a great magnetic storm, one of the most intense ever recorded. It arrived at a poignant moment in history, when…

Magnetic Chips Can Boost Computer Efficiency

In a breakthrough for energy-efficient computing, engineers at the University of California-Berkeley have shown for the first time that magnetic chips can operate with the lowest fundamental level of energy dissipation possible under the laws of thermodynamics. The findings mean that dramatic reductions in power consumption are possible as much as one-millionth the amount of…

Some Guy Made A Thor’s Hammer That Only He Can Lift

Turns out you don’t need to step out of a Marvel comic to have superhero strength. You just need a bit of engineering know-how. As you can see in the viral video above, Allen Pan–whose Twitter page identifies him as a Los Angeles-based engineer and “imagination man”– built a Thor’s Hammer that only he can lift. Pan…
