An international team of researchers led by Leiden University (the Netherlands) has mapped nine gigantic collisions of galaxy clusters. The collisions took place seven billion years ago and could be observed because they accelerate particles to high speeds. It is the first time that collisions of such…

Sander Blok has won the third edition of the annual LION Image Award. He created a colorful image of gold nanoparticles with a low-energy electron microscope.

There have been indications for decades that there is a link between increased iron levels in the brain and Alzheimer’s disease. Leiden physicists find this connection as well, thereby now making a distinction between different forms of iron. They identify specific iron forms that increase in Alzheimer’s…

Cosmologists have many possible models for the Universe, of which only one can be true. A new flowchart will eliminate some of them when two specific Universe features are accurately measured. Publication in Physical Review D on 7 November.

An important discovery makes it possible to communicate complex information among multiple people without the message being cracked. The communication can also relate to complex information.

The compulsory reading list is infamous among secondary school students, and for all the wrong reasons. This prompted the Faculty of Humanities and the Onderwijsnetwerk Zuid-Holland (South Holland Education Network) to launch the Alternative Reading List Award, in search of books that motivate young…

Our solar system probably evolved in the same way as most of the other planetary systems around us. This has been shown by German-Austrian-Dutch research on more than 870 planet-forming disks in the Orion cloud A. The five researchers, including three from the Leiden Observatory, published their findings…
