Underwater power cables make lobsters bad swimmers

Lobster larvae exposed to the electromagnetic field of underwater power cables can't swim as well, a new study published in Journal of Marine Science and Engineering shows. They're also three times more likely to be deformed ...

Quantum physics sets a speed limit to electronics

How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits. The quantum-mechanical processes that enable the generation of electric ...
