The air is full of DNA — here’s what scientists are using it for

When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at HZDR have now observed this ionization process in more detail than ever before. To do so, they combined two state-of-the-art lasers: the X-ray free-electron laser and the high-intensity optical laser ReLaX at the HED-HiBEF experiment station at the European XFEL in Schenefeld, near Hamburg. Their f

In a new paper published in the British Journal of Sociology of Education, University of Sheffield researchers argue that the modern university experience is increasingly defined by stifling targets and material pressures.
