Satellite observations reveal secrets of dry tropical forest greening

In dry tropical forests, vegetation takes up water at the end of the wet season and stores it during the driest season of the year. This large amount of stored water enables trees to flush new leaves about one month before the next rainy season. This surprising phenomenon has been revealed for the first time using satellite observations, mainly in the African region of Miombo (around four times the surface area of France), in a study coordinated by the University of Copenhagen and INRA in collaboration with the CEA, CNRS, CNES and Bordeaux Science Agro.

A new technique to encapsulate biomolecules

Scientists from INRA, CNRS and Université de Bordeaux have managed to develop a new technique that enables the production of microparticles that can spontaneously store biomolecules (colloidosomes). For the first time, they have designed such an encapsulation system in water, without using either solvent or oil. These findings open perspectives for the development of new types of capsules containing active substances, and more generally for the creation of artificial cells.
