Plasticspotters
De Grachtwacht doet onderzoek naar stadsnatuur en de impact van plastic op de natuur. Met onze clean-ups verzamelen we niet alleen afval, maar ook data. Zo proberen we de bron van het afval te achterhalen en de kraan aan wal dicht te draaien. Zo komt er structureel minder plastic in de gracht!

Towards a single-molecule FRET study of Frauenfelder's nonexponential rebinding of CO in myoglobin
Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

Withstanding the cold: energy feedback in simulations of galaxies that include a cold interstellar medium
Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Monitoring drought and salinity stress in agriculture by remote sensing for a sustainable future
Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…
