Remaining vertical: a feat of perception for plants

Contrary to what happens in humans, plants use gravitational perception to distinguish their angle of inclination while not being destabilised by weight and acceleration forces. In a study that has just been published in Scientific Reports, researchers from INRA, CNRS and the Université Blaise Pascal demonstrated that while plants sway considerably in the wind, they do not experience such movement as a loss in vertical positioning. This research opens the door to promising applications in agricultural sciences and biomimetics, such as for the development of miniaturised position sensors.

Cutting down on salt, fat and sugar in diets

Cheese, chorizo, dry sausages, muffins, madeleines, custards and pizza sauce: for four years, these foods have been getting a makeover with the INRA-coordinated European project TeRiFiQ. Scientists and industry players have managed to significantly cut back on their salt, sugar and fat content without compromising their nutritional and sensorial qualities or jeopardising consumer acceptability. The final report of the project is now available online on the European Commission’s website: http://url.inra.fr/2emJxoD
