Astronomers from Leiden Observatory have developed a new method to find distant quasars and better distinguish them from other objects that look like them, using machine learning techniques. The research result has been accepted for publication in the journal Astronomy & Astrophysics. It is the last…

Astronomers have used data from the European Gaia Space Telescope to discover 55 high-speed stars launched from the young star cluster R136 in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. This increases tenfold the number of known “runaway stars” in this region. The team of astronomers,…

It came as a shock to many people: one million plant and animal species are threatened to become extinct. But this number isn’t the most relevant aspect, argue Alexander van Oudenhoven, Koos Biesmeijer and three other experts in Dutch newspaper Trouw. ‘It is more important to realise that the fate of…

The discovery reaffirms that the conditions that spawned the Earth and Sun are not unique in the Universe. The results are published…

For the first time ever, Leiden biologists have found that the ‘nose’ of spirochetes – worm-shaped bacteria – have a two-fold symmetry. A remarkable discovery, as the ‘nose’ of every other bacterium has been found to have a six-fold symmetry. First author Alise Muok wrote a popular blog about the findings…

An international group of scientists has drawn up five ethical guidelines to ensure that this DNA research is better regulated. Leiden archaeologist Marie Soressi – one of the signatories - explains…

An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

The Hortus Botanicus is celebrating its 425-year anniversary this year. It’s the oldest botanical garden in the Netherlands, but how did it come into existence and what kind of research takes place there?

We need to dispel the arrogant and misguided idea that modern humans are superior to earlier human species. It is thanks in part to all our predecessors such as Neanderthals that we are who we are today. This is what Marie Soressi, Professor of Hominin Diversity Archaeology, will argue in her inaugural…

An international team led by Leiden astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarised light from an exoplanet. From this light they can deduct that a disk of dust and gas orbits the exoplanet. In this disk moons are possibly…

A flint tool covered with a tar-like substance has turned out to be a top scientific find. Research by a Dutch team of scientists showed the find to be a piece of birch tar that was extracted 50,000 years ago by Neanderthals using complex techniques. The tar was used as an adhesive to make it easier…

By adding their signature to the collaboration agreement on 31 May, Leiden University, TU Delft, space research institute SRON and NWO confirmed the move of SRON from Utrecht to South Holland. From 2021, the headquarters of the space research institute will be located on the Campus of Leiden Univ…

Over the years, many spectacular archaeological finds have been washed ashore on the Dutch coast. Among these a large assemblage of barbed points made of bone and antler from the Mesolithic (11,000-8000 BC). The species used by Mesolithic hunter-gatherers to manufacture their barbed points remained…
