    "body_text": "UC Davis and Berkeley Lab researchers fired deuterium ions into palladium and titanium foils prepared by different loading methods. Below 2.5 kiloelectronvolts, some samples showed fusion rates vastly above the bare-reaction expectation, forming an unexpected plateau that depended on the material environment. Electrons and defects may partly screen repulsion, but the mechanism is unresolved. The experiment concerns low-energy reaction physics and possible neutron sources, not a demonstrated power reactor.",
