Phys.org / Krill buildup could slow fin whale filter-feeding unless baleen stays 15% clear

Usually there's safety in numbers, but it doesn't always work that way. Fin whales (Balaenoptera physalus) filter-feed on immense shoals of krill, engulfing colossal mouthfuls of water containing up to 144 kg of the crustaceans. ...

Medical Xpress / Medical AI may look less biased on paper but not in practice, new study finds

Large language models (LLMs) are only as good as the data they learn from. If their training data contains social biases, the models may unintentionally repeat those biases in their responses. As their use increases with ...
