Nanoantennas combined with phosphor plates enable increased photoluminescence
White LEDs may soon be dethroned as the world's go-to light source by an alternative with a much better sense of direction.

A team of researchers from Tsinghua University, working with a colleague from Jilin University, has developed a new 3D nanoprinting technique that uses semiconducting quantum dots. In their paper published in the journal ...
How animals are able to interpret natural light sources to adjust their physiology and behavior is poorly understood. The labs of Kristin Tessmar-Raible (Max Perutz Labs Vienna, Alfred Wegener Institut, University of Oldenburg) ...

For signals barely larger than the noise in a system, measurement is generally a trade-off between speed and precision. Averaging over several measurements reduces the influence of noise but takes (a lot of) time. That could ...
