Making molecules dance to our tune reveals what drives their first movements
Bringing ultrafast physics to structural biology has revealed the dance of molecular -coherence- in unprecedented clarity. How molecules change when they react to stimuli such as light is fundamental in biology, for example during photosynthesis. Scientists have been working to unravel the workings of these changes in several fields, and by combining two of these, researchers have paved the way for a new era in understanding the reactions of protein molecules fundamental for life.

Can rainbows monitor the environment?
New nanotechnology may make it easier to identify the chemical composition of impurities and their geometrical shape in samples of air, liquid and live tissue. Using conventional testing techniques, it can be challenging - sometimes impossible - to detect harmful contaminants such as nano-plastics, air pollutants and microbes in living organisms and natural materials.
