Human bodies are not quite as dark as they look. A growing body of research suggests that living tissue constantly releases an ultraweak glow, a stream of photons that appears to switch off when life ...

Chemists have discovered a way to use visible light to synthesize a class of compounds particularly well suited for use in pharmaceuticals. The class of compounds, called azetidines, had been ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...
