Plant Architectures that Reflect Universal Network Design Principles

It might seem like a tomato plant and a subway system don’t have much in common, but both, it turns out, are networks that strive to make similar tradeoffs between cost and performance. High-resolution laser scanning reveals plant architectures that reflect universal network design principles. Using 3D laser scans of growing plants, …

Light emitting transistor using carbon nanotubes

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University (Germany) and the University of St Andrews (Scotland) used light-emitting and extremely stable transistors to reach strong light-matter coupling and create exciton-polaritons. These particles may pave the way for new light sources, so-called …
