A huge shiny aluminium object stands in the middle of the Polderlab in Oud Ade. Are the researchers trying to make contact with extraterrestrial life? Certainly not; they are using the ’Moon landers’ to measure whether innovative forms of agriculture reduce greenhouse gas emissions. Fleur van Duin works…

It's now possible to measure how many plastic particles there are in our food. Chinese scientists and Leiden professor Willie Peijnenburg applied their new method to lettuce and wheat. Their results were published January 20 in Nature Nanotechnology.

More severe droughts that will also last longer: this will primarily be a problem for irrigated croplands, as discovered by environmental scientist Qi Chen. Mixed forests with a variety of plant species will be the least vulnerable. Chen compared the effects of drought on different ecosystems across…

In supermarkets, consumers are drowning in a sea of sustainability labels. Confusing for them, but also farmers can't see the forest for the trees. Obtaining these labels demands an enormous amount of time and effort. Berent Baris is investigating ways to simplify this process, benefiting both farmers…

On 9 September, in the presence of King Willem Alexander, Secretary of State Sander Dekker presented the Spinoza Prize to four researchers, including two researchers from Leiden: archaeologist Corinne Hofman and physicist Dirk Bouwmeester.

Imagine that you need to travel, but you don’t have a car and you’re dead broke. What do you do? Hitchhiking, of course! Leiden biologists found that certain bacteria use this very same tactic: their spores hop on motile bacteria and use them as a taxi, ensuring they reach the right environment to f…

Local residents, scientists and students are investigating riverbanks in Leiden for the 'Bank Plants' citizen science project. Which plant species are found where? And how can the municipality of Leiden improve its riverbank management to ensure optimal biodiversity?

With a single sample of water or soil, researches can analyse the DNA of everything that is living in that environment. During her research, PhD candidate Beilun Zhao discovered a way to analyse not only the kind of species, but also the age of the species in a water sample. The method showed its first…

She has had the idea for seven years, but now environmental scientist and conservation biologist Kat Stewart finally gets to work on it. She has been awarded a Vidi grant by NWO to find out how DNA from water can be used to shed light on invasive species and their impact on native populations.

Soil that is too wet, or too dry. Or with a lot or few nutrients. Due to climate change, the differences are becoming bigger, and plants must increasingly be able to adapt to survive. How do you make plants more stress-resistant? For this purpose, researchers from Leiden, along with other universities,…

The world is becoming clogged with plastic, with tiny plastic particles found everywhere, from the oceans’ depths to the mountain tops, soil, plants, animals and even inside us. The question is: what harm, if any, are they causing? In a new article on The Conversation, environmental scientists Meiru…
