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) ...
