Abstract: I will review the problems caused by light scalar fields in particular with respect to gravitational tests and consider a new type of screening mechanism which allows to evade them. This involves two fields, an axion-like field and a dilaton, for which I will also present new results on their cosmology and a link to early dark energy.
