Is everything in the universe made up of vibrating one-dimensional strings? For the first time, scientists think they can concretely test string theory, the mind-blowing “theory of everything” that has dominated physics for the past two decades. It turns out that string theory predicts the behavior of entangled quantum particles, which can be tested in a lab — therefore testing string theory.
A new nano-scale wiretap device could tell researchers about the inner workings of cells, according to a new Harvard study.
It involves a transistor that can take electrical readings, embedded inside a membrane that fits inconspicuously inside an individual living cell. The tiny probe, which is smaller than many viruses, is the first semiconductor device to take measurements of the inside of a cell.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
