The recognition that there may be more, so-called allosteric binding sites on a given receptor has also fueled our synthetic efforts. Over the last few years we have focused on many drug targets (adenosine A1, A2A and A3 receptors, the mGlu2 receptor and a classic ‘anti-target’, the hERG channel) to…

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…

A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar…

Many hot, rocky planets outside of our own solar system started out as large, gaseous Neptunes. This is what astronomers at Leiden University contend in a recent online publication.

In a full lecture hall C1 the Faculty of Science started off the new academic year on Tuesday 5 September. The theme of the meeting was, just as it had been at the university's opening the day before, sustainability.

On Monday 9 May Mercury will pass between the Earth and the Sun. This rare event can be followed in the Leiden Observatory. The Observatory's new solar telescope produces a very clear image and offers a unique opportunity to observe Mercury at the highest magnification possible in the Netherlands.
