Deep down in the seafloor anaerobic microbes consume large amounts of methane, a potent greenhouse gas when it enters […]

A train of short proton bunches travels through the plasma field, forming a wave on which electrons can be accelerated. Credit: AWAKE Important milestone for next-generation acceleration experiment. The future of particle acceleration has begun. Awake is a promising concept for a completely new method with which particles can be […]

Superconductivity is a complete loss of electrical resistance. Superconductors are not merely very good metals: it is a fundamentally different electronic state. In normal metals, electrons move individually, and they collide with defects and vibrations in the lattice. In superconductors, electrons are bound together by an attractive force, which allows […]
