Une machine à remonter le temps vers l’état le plus stable
Le logiciel open source GEMS permet de calculer la chimie de systèmes complexes. Un nouveau consortium national garantit désormais son développement à long terme.
Pourquoi les cellules réagissent de manière «anormale» avec l’âge
Des scientifiques du PSI ont élucidé la raison pour laquelle les cellules de notre organisme, quand elles vieillissent, réagissent différemment des cellules jeunes. Leurs recherches sur des cellules cutanées humaines ont montré que la structure dans laquelle est empaqueté le patrimoine génétique à l’intérieur du noyau cellulaire, appelée chromatine, joue un rôle central dans ce phénomène.
Imaging electrical switching of ultraefficient memory devices
SLS illuminates how electrical switching in layered materials works
Hypotenseur commutable à la lumière
De l’arrêt à l’activation: des scientifiques du PSI ont observé comment l’effet d’un médicament contre l’hypertension artérielle pouvait être activé et désactivé en exposant ce dernier à la lumière.
