Upgrading ALICE: What's in store for the next two years?

With massive red doors weighing 350 tonnes each, it takes more than uttering "open sesame" to open the ALICE detector. Behind the doors lie the inner workings of a unique detector built to study the conditions of matter moments ...

X-ray photoelectron spectroscopy of hydrogen and helium

For the first time scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it's impossible to obtain X-ray photoelectron spectroscopy (XPS) spectra ...

Innovative method enables new view into Earth's interior

An innovative X-ray method enables new high-pressure investigations of samples under deep mantle conditions. The technique, which was developed by a team led by Georg Spiekermann from DESY, the German Research Centre for ...

Life on the edge in the quantum world

Quantum physics sets the laws that dominate the universe at a small scale. The ability to harness quantum phenomena could lead to machines like quantum computers, which are predicted to perform certain calculations much faster ...

A laser system built on principles of supersymmetry

A team of researchers from the University of Central Florida and Michigan Technological University has developed a laser system concept built on the principles of supersymmetry. In their paper published in the journal Science, ...

Sound and light trapped by disorder

Sound and light are crucial for our life and are essential in many energy, communication and information technologies. Their interaction allows many fundamental observations in physics, from the detection of cosmic gravitational ...

Scientists discover new type of magnet

A team of scientists has discovered the first robust example of a new type of magnet—one that holds promise for enhancing the performance of data storage technologies.

Scientists simulate a black hole in a water tank

Certain phenomena that occur in black holes but cannot be directly observed in astronomic investigations can be studied by means of a laboratory simulation. This is possible due to a peculiar analogy between processes that ...

Discovering new particles using black holes

Some theories that go beyond the Standard Model of particle physics predict the existence of new ultralight particles, with masses far below the lightest known particles in nature. These particles have such very weak interactions ...
