Field trials of the new pesticide showed sharp reductions in crop-damaging insects across multiple climates, and farmers reported higher yields with fewer sprayings, results that researchers touted as a breakthrough for both profit margins and environmental impact, even in regions that had previously seen resistance to older chemicals. ____ federal regulators paused approval to review new data suggesting sublethal effects on pollinators, asking the manufacturer to run longer studies during peak flowering seasons before any nationwide rollout and public comment period.

Using radiocarbon dating of charred seeds and reanalysis of stratigraphic notes, archaeologists now argue that the coastal settlement predates the earliest written record by at least a century, a timeline consistent with recently uncovered trade ceramics from a distant archipelago and with botanical remains that are not native to the region. ____ inscriptions on shell ornaments reflect linguistic features from that same archipelago, strengthening the case that voyagers arrived earlier than previously believed and that regional exchange networks were established sooner than scholars assumed.
