Abstract: Aspects of the present disclosure are directed to a method for providing differentiated access in a media subscription platform. The method may comprise: maintaining a data store that associates subscribers with subscription tiers and stores a permission policy defining allowed subscriber interactions with media items supplied by creators. The method comprises receiving, from a client device of a premium tier subscriber, a request relating to a referenced media item. The method comprises determining, from the permission policy, at least one content-interaction mode permitted for the subscriber with respect to the referenced media item. The method comprises generating, by an AI model selected based on the content-interaction mode and permission policy, modified content, supplemental content, or generative content.

Abstract: Aspects of the present disclosure are directed to a system having at least one processor and memory instructions executable by the at least one processor to maintain a data store that associates subscribers with subscription tiers and stores a permission policy defining allowed subscriber interactions with media items supplied by creators. The instructions further cause the system to receive, from a client device of a premium tier subscriber, a request relating to a referenced media item. The instructions further cause the system to determine, from the permission policy, at least one content-interaction mode permitted for the subscriber with respect to the referenced media item. The instructions further cause the system to generate, by an AI model selected based on the content-interaction mode and permission policy, modified content, supplemental content, or generative content. The system may generate interactive visualizations that respond to one or more aspects of the referenced media item.

Abstract: Provided are compositions and methods for treating bacterial infections. It is demonstrated herein that bacteria cell wall materials stimulate germination of spores of Gram-positive bacteria, and that such activity requires Ser/Thr kinase PrkC. By modulating one or both, spores (which can be antibiotic resistant) can be stimulated or inhibited from germination, which can be exploited in various methods of therapeutic treatment. Also provided is a method of modulating germination of a spore of a Gram-positive bacterium. Also provided is a method of decontaminating an environment.
