Science news today spans both the deep past and a high-stakes technological future. In a deal likely to reverberate across the Middle East, the U.S. and Saudi Arabia have reportedly agreed on a civil nuclear partnership that would bring American reactor technology to the kingdom and potentially allow local uranium enrichment, a provision sure to face congressional and nonproliferation scrutiny. In the corporate technology sphere, Amazon is cutting jobs in its AGI research arm, framing the move not as a retreat from artificial intelligence but as a sharper focus on projects with clearer customer impact. Citadel Securities, meanwhile, is expanding in Europe with a new Amsterdam office, underscoring how global finance continues to reposition itself around key regional hubs. And from Australia comes a reminder of science’s longer view: archaeologists say Cloggs Cave preserves evidence of grass-burning rituals practiced by the GunaiKurnai people for some 25,000 years.
