Nausea, neurologic pain and hair loss: some of the severe side effects of chemotherapy. Not necessary, biochemist Liyan Zhang showed. Together with Leiden biologists and others, she achieved great results with a drug that is only active in combination with light. Zhang will defend her PhD on 4 July.

The night side of exoplanet WASP-43b, to the surprise of astronomers, does not appear to contain methane. It is likely that extreme winds do not allow enough time for methane to form in detectable amounts. This is the conclusion of an international team of scientists, with Leiden and Amsterdam contributions,…

An international team of astronomers including Leiden professor Ewine van Dishoeck has observed the benzene molecule (C6H6) in a planet-forming disk around a young star for the first time. The observations tell us more about the forming of planets in this disc, like our own Earth. The scientists publish…

Researchers from Leiden University analysed almost 30 years of communication on astrobiology. News articles proved most speculative, especially via quotes from scientists. Especially exoplanet research is often accompanied by high expectations about extraterrestrial life, they write in PLOS One.

To what extent does exoplanet Proxima b resemble our Earth? And is there some form of life present? Astronomers hope to find answers to these questions with the new European Extremely Large Telescope (ELT). An NWO research grant of €18 million will allow a Dutch consortium to continue building instruments…

The two instruments of ESA's space telescope Euclid have taken their first test images. The first images indicate that the space telescope will achieve the scientific goals for which it was designed - and possibly much more. Euclid will create a 3D map of a third of the sky, allowing scientists to study…

For the first time, an international group of astronomers have seen the heat glow of two ice giant planets colliding. They could also observe the resultant dust cloud move in front of the parent star several years later. Led by Leiden astronomer Matthew Kenworthy, they monitored the star's brightness…
