Engineered biofilms: a case for harnessing microbial communities to support long‑duration missions An international study published in npj Biofilms and Microbiomes argues biofilms—microbial communities usually targeted for removal—should be engineered, not eliminated, aboard spacecraft. Researchers outline how managed biofilms could protect crew health, support crop systems and reshape microbiome management for Moon and Mars missions.

Rubin Observatory to pair with neutrino alerts and rapidly boost core-collapse supernova discoveries The Milky Way hasn't seen a directly observed core-collapse supernova in roughly a millennium, despite expectations of one to two per century. The Vera Rubin Observatory, leveraging its wide-fast-deep survey and real-time neutrino detector alerts, should rapidly identify far more supernovae, enabling prompt multi-messenger follow-up.

JWST 'Little Red Dots' flagged as candidate nurseries for direct-collapse supermassive black holes JWST has detected compact sources dubbed 'Little Red Dots' that researchers say may be the first direct observational evidence of direct-collapse supermassive black hole formation. If confirmed, these objects would pinpoint the birth sites of the universe's most massive black holes and reshape early-galaxy assembly models.
