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.…

Mathematical model predicts drug concentration in the brain
Do medicines arrive in the right amount at the right spot in our brain? By making a model that depicts our brain in small 'brain blocks', Esmée Vendel tries to find an answer to this question. Her new, mathematical model predicts the concentration of medicines in the brain over time and space. Vendel…
