    "body_text": "Rutgers-led simulations add turbulence and frazil-ice formation to a long-debated route through Europa's ice shell. Water forced upward from the deep ocean would mix against cold fracture walls, supercool, and seed crystals that can block narrow cracks within hours. Wider fractures remain possible only under demanding conditions, so a shallow reservoir may have melted locally instead of sampling the ocean below. Europa Clipper and JUICE can test the shell's structure, but the model does not show that any reservoir exists.",
