News at a glance: Trump turmoil, New Zealand's funding overhaul, and an AI expert tripped by AI

Following through on his vows to shake up the U.S. government, President Donald Trump's new administration quickly issued a flurry of executive orders and other decisions, some with big implications for research and global health, sowing worry and confusion among many scientists. The White House this week proposed--and 2 days later rescinded--an unprecedented order to freeze huge chunks of federal spending, including research grants. The 27 January budget memo directed political appointees at every agency to decide whether the funds "conform with administrative priorities" as spelled out in a slew of executive orders Trump has issued since taking office. Despite withdrawing the memo, the White House said agencies must still comply with the executive orders, which ban support for programs that include promoting "Marxist equity, transgenderism, and Green New Deal social engineering policies." A federal judge had already temporarily halted implementation of the memo, which generated a public outcry.
