Researchers compared Bi-2212 and Nb3Al under identical room-temperature electron irradiation, revealing a significant difference in their responses to damage. Bi-2212 progressively lost its crystalline order and became fully amorphous, while Nb3Al retained its crystal structure even after a substantially longer exposure. The study prov...
A new study from the University of Bath warns that over-reliance on generative AI may weaken managers' ability to build moral insights, contextual understanding, and practical know-how. The research suggests that AI can strengthen managerial judgement when used as a tool for reflection, rather than a replacement for thinking.
A new study demonstrates TanSat-2's ability to distinguish between human carbon emissions and ecosystem carbon sinks. The satellite's observations of CO2 and chlorophyll fluorescence can simultaneously constrain net primary productivity and fossil fuel combustion emissions, leading to significant error reductions.

Researchers found that Miracinonyx trumani preyed almost exclusively on fish, challenging the long-held assumption that it was a fast-running prey-chaser like modern cheetahs. The species shared a common ancestor with modern cheetahs about 4.7 million years ago, but diverged from a common ancestor with pumas about 2.6 million years ago.
A new study by UC Santa Cruz scientists has discovered that the extinct North American cat, Miracinonyx trumani, was not a true cheetah but a highly adaptable relative of the puma that specialized in eating fish to survive in the Arctic. The species' unique genetic blueprints allowed it to thrive in extreme environments, but its low ge...
