Leiden biotech startup Azafaros has successfully completed a funding round, raising 25 million euros of investments for developing treatments of rare metabolic disorders. The company holds exclusive license to a library of novel patented compounds discovered by experts from Leiden University.

Global warming, deforestation, nature conservation. All major environmental challenges that call for major measures. To see what the effects of these measures are, observation data from the Earth is used. Researchers at LIACS receive €90,000 from the European Space Agency (ESA). With this they are investigating…

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.

We have to do all we can to stop climate change. But: the Earth is more resilient than we thought. That is the surprising conclusion of an international team of ecologists and mathematicians, which included Leiden mathematician Arjen Doelman. The team discovered that ecosystems can still avoid tipping…

A circular economy in which all resources are reused is a prerequisite for a sustainable world. As EU president, the Netherlands can give a firm impetus to this economic shift. This is the message of Leiden Professor of Industrial Ecology, Arnold Tukker, in his inaugural lecture on 26 February.

Science is typically a patchwork of research contributions without much coordination. Especially in clinical trials, the follow-up studies that we do fail to be the most promising.

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.
