Paleomagnetic evidence for a nebular magnetic field from calcium-aluminum-rich inclusions

The initial stage of planet formation is expected to take place in a nascent protoplanetary disk (PPD) accreting onto the protostar embedded in an infalling envelope. This stage is likely accompanied by the formation of high-condensation temperature solids resembling calcium-alum...

Thermal bottlenecks constrain early-life survival of native fish in regulated rivers

Climate change is reshaping thermal regimes worldwide, threatening species whose early development depends on narrow temperature ranges. Yet directly linking warming to reproductive failure in wild populations remains intractable, particularly in aquatic ecosystems. We developed...
