Dutch astronomers photograph possible toddler planet by chance
A group of astronomers was actually examining the dust disc around the young double star CS Cha, when they saw a small dot on the edge of their images. It turned out to be a small planet of only a few million years young, which moves along with the double star. Whether it is a super-Jupiter in the making…

Report: Tracking down green spaces in The Hague in places you don't always want to be
Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

Together, plants and fungi could slow down climate change
A special relationship between plants and fungi, which plays an important role in carbon storage in soil, has the potential to slow down climate change. However, the amount of carbon stored in soil is decreasing as a result of human activity. This is what researchers say in a publication in Nature Communications.…
