Ancient altercations between musk turtles and alligator gar recorded in Florida's fossil record

Ancient altercations between musk turtles and alligator gar recorded in Florida's fossil record Lisa Lock Scientific Editor Robert Egan Associate Editor Sometime between 5.5 and 5.6 million years ago, two shell crushers squared off in the languid currents of an ancient Florida river. The fossils they left behind, discovered by paleontologists at the Florida Museum of Natural History, reveal the identity of the combatants and the outcome of their encounter. In one corner, weighing in up to...

Australian Aboriginals cared for a dingo's grave for decades

A thousand years ago, the ancestors of today's Barkindji people carefully buried a dingo (or garli, in the Barkindji language) in a mound of shells. Archaeologists recently studied the burial in what's now New South Wales, Australia. They found that the Barkindji ancestors had buried the dingo with the same care and ceremony as any beloved human member of the community and looked after the grave for centuries.

Stanley Cup Final player rankings: Hart, Andersen,...

The 2026 Stanley Cup Final has arrived, and it represents the central tension of the 2026 playoffs. On the one hand, it's not a surprise to see the Carolina Hurricanes skating for Lord Stanley's Cup because they were the East's best team by record all season. Then again, this team had a long history of falling short of the Final before this year -- a trend the Hurricanes finally defied.

Nonparametric LLM Evaluation from Preference Data

arXiv:2601.21816v2 Announce Type: replace Abstract: Evaluating the performance of large language models (LLMs) from human preference data is crucial for obtaining LLM leaderboards. However, many existing approaches either rely on restrictive parametric assumptions or lack valid uncertainty quantification when flexible machine learning methods are used.

Whole-genome duplication shaped cell-type evolution in the vertebrate brain

Abstract The complex brains of vertebrates have more cell types than those of their closest relatives. Whole-genome duplications (WGDs) occurred during early vertebrate evolution1, but it is unclear whether the duplicated genes (ohnologues) facilitated cell-type evolution. Here using brain single-cell transcriptomes from five chordates—human2, mouse3, lizard4, lamprey5 and amphioxus—we report that many cell-type families with conserved core transcription factors in vertebrates do not show...
