What people are saying
The discussions reflect a strong fascination with selenomelanin's promising ability to block radiation, especially in space-related contexts, as exemplified by phrases like 'extreme radiation shielding' and 'space radiation for astronauts.' The tone varies from enthusiastic admiration to speculative interest, with words like 'fascinating,' 'game changer,' and 'super sunscreen' highlighting the perceived significance and innovative potential of the research, which collectively contribute to the high impact perception.
Most posts express support for the potential applications and significance of selenomelanin, highlighting its radiation shielding properties and potential for space exploration or medical use.
Posts show high curiosity, with multiple mentions of space, space radiation, and advanced materials, indicating strong engagement with the scientific novelty.
Several discussions cite specific research details, experiments, or implications, demonstrating a moderate depth of engagement beyond surface-level reactions.
Many posts suggest the research could have substantial influence, especially regarding space exploration and protection against radiation, emphasizing its transformative potential.
Abstract in brief
- Melanins are diverse biopolymers found in various organisms that serve as pigments and protect against radiation, with five main types known: eumelanin, neuromelanin, pyomelanin, allomelanin, and pheomelanin.
- Recent studies suggest that pheomelanin may absorb X-rays better than eumelanin, leading to the hypothesis that a selenium-enriched melanin (selenomelanin) could provide superior radiation protection due to selenium's higher atomic number.
- Research introduces selenomelanin as a structural mimic of pheomelanin, showing it effectively prevents damage to human skin cells from X-ray exposure, indicating it could be a new, naturally occurring type of melanin.

@robinhanson One possibility mentioned in https://t.co/oz85uPjUTM is that melanin also works by quenching free radicals rather than catching radiation. Slightly contradicted by the radiation measurements, but there could well be a double effect.
