恐龙粪便中发现保存最完好的白垩纪鸟类羽毛

科学家在蒙大拿州地狱溪组发现的一块恐龙粪化石中，发现了保存异常完好的晚白垩世鸟类羽毛。这些羽毛被描述为该时代保存最完好的羽毛，为了解鸟类进化和白垩纪-古近纪灭绝事件提供了关键见解。研究表明，像反鸟类这样的水鸟的羽毛可能对保暖效果不佳，这导致它们比幸存下来并成为现代鸟类祖先的新鸟类灭绝。 AI

本文如何被排名

Signal score: 4 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 该集群报道了一篇详细介绍化石鸟类羽毛发现的科学论文。[lever_c_demoted from research: ic=1 ai=0.1]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: paper, other; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: Low; Off-topic or adjacent — cluster remains reachable but doesn't surface in AI-industry rankings.
Story freshness: Breaking (< 6h); Fresh story with cross-source coverage still developing. Ranking may shift as more sources report.

科学家发现水星收缩速度远超我们想象

The planet’s radius may have shrunk by between four and six miles since it was formed due to global cooling, a contraction that is up to 30 percent larger than previously estimated.
