Star-eating black hole could power cosmic particle accelerator
Briefly

An unusual microquasar has been identified as potentially producing high-energy γ-rays, suggesting it could act as a natural particle-accelerator or PeVatron, which may clarify cosmic ray origins.
The development of a 'smart' insulin molecule that adjusts its activity based on blood glucose levels offers new hope for diabetes management, reducing risks associated with hypoglycemia.
