Whales in the vicinity of the city of Auckland, New Zealand consume large amounts of microplastics every day. A team of international researchers reached this conclusion after carefully examining whale poop. The team included Thijs Bosker, Associate Professor in Environmental Sciences at Leiden University…

The LUF International Study Fund (LISF) will make changes to its allocation process following an investigation into diversity in its grants policy. This investigation, which was carried out for the LISF by, among others, former committee member Mariska Kret and master’s student Marjolijn Wijnen, has…

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star at which planet formation has finished, while the same-aged companion star still has a planet-forming disk. The researchers…
