Very new to this but everyday they create and curate new engaging content. Available on both iOS/Android. You can follow subjects that interest you. Lots on natural sciences.

edX is a one-stop-shop for anything. They have tons of courses about the natural sciences too - MIT & Rice University both offer some bio courses, after a quick perusal. Worth checking out! 👨‍🏫

Khan Academy is a great go-to when you need a short explanation of a specific subject. They cover basically everything, from economics, to biology, to chemistry. Mostly aimed a high school/college demographic though!
