Minims are letters that are made up of short, vertical pen strokes, such as 'm', 'i', 'n' and 'u'. In Gothic script, there is often little distinction between letters composed of minims. Assistant professor of medieval literature Krista Murchison has written an article in History Today on the hidden…

The discovery that eleven asteroids might collide with our Earth has become world news. The research of three Leiden astronomers has appeared on more than 190 news sites worldwide, from America to China. They developed and trained an artificial neural network for this discovery.

The transition from Middle to Upper Paleolithic is a major biological and cultural threshold in the construction of our common humanity. Technological and behavioral changes happened simultaneously to a major climatic cooling, forcing human populations to develop new strategies for the exploitation…

In 1925, two young physicists from Leiden University, George Uhlenbeck and Samuel Goudsmit, proposed a radical idea: spin. Their bold hypothesis quickly came to play a key role in physics and formed the basis for later breakthroughs in quantum mechanics. We are celebrating the anniversary of this discovery…

The METIS instrument that’s being built for ESO's future Extremely Large Telescope (ELT) in Northern Chile under the leadership of the Dutch Research School for Astronomy (NOVA) has reached an important milestone: the preliminary design has been approved.

Astronomers Professor Christoph Keller and Dr Frans Snik will be developing a commercial module for measuring fine particulates. They have been awarded an STW Demonstrator subsidy of 138,000 euros.

Professor Joanna Aizenberg (Harvard University) is the recipient of the 2017 Havinga Medal. She is awarded for her eminent and original contributions to the field of biologically inspired materials science.

The design for the METIS instrument for the Extremely Large Telescope (ELT) is final. The European Southern Observatory (ESO) has given the green light for production of all parts of the instrument. It is the first ELT instrument, designed and to be built under Dutch leadership, to formally pass the…

Four scientists from Leiden University have each been awarded a Starting Grant by the European Research Council (ERC). This grant, worth up to two million euros, gives researchers the opportunity to head up a research team for five years.

Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use special equipment to reveal what is taking place under the surface.

This is a recording of the book launch of Susanna Lindberg's
