Switching DNA functions on and off with light

DNA is the basis of life on earth. The function of DNA is to store all the genetic information an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell. Biochemists ...

Physicists couple key components of quantum technologies

Quantum effects are genuinely found in the world of nanostructures and allow a wide variety of new technological applications. For example, a quantum computer could in the future solve problems, which conventional computers ...

Studying cosmic expansion using methods from many-body physics

It is almost always assumed in cosmological calculations that there is a even distribution of matter in the universe. This is because the calculations would be much too complicated if the position of every single star were ...
