Donald Trump has spent much of his second term at war with science and scientists. He is cutting staff at institutions such as the Environmental Protection Agency (EPA) by a third, and has cancelled or frozen up to 8,000 federal research grants. This hasn’t just hurt individual research programmes, it has damaged America’s credibility as a reliable partner in the scientific community. It is not surprising that many researchers – one poll last year by the journal Nature gave the number of 75% – say they are considering leaving the US entirely.
在微信所主导的社交领域上，抖音显然从未放弃过布局。2024年3月，抖音推出“合养精灵”功能：只要与好友连续互发消息3天，双方即可点亮“火花”标识；连续互发6天，则可以邀请对方共同养一只“小火人”。随着互动天数的增加，火花数值与小火人等级同步提升；一旦超过24小时未产生互动，火花与小火人便会变为灰色，若在规定时间内未恢复互动，甚至会彻底消失。
