Science Daily is a science news aggregator, not a primary source; the original study is likely peer-reviewed, but the highlight does not provide a direct link or DOI. The provenance tier is aggregated/secondary with no primary cited, so the claim's solidity is moderate—credible but not independently verifiable from this item alone.
