- 1Earth absorbing heat equal to four Hiroshima bombs every second●Climate is accumulating 4 Hiroshima atomic bombs worth of heat per second
A widely shared statistic states that the world's oceans and atmosphere are trapping heat at a rate equivalent to the energy of four Hiroshima atomic bombs every second. The figure illustrates the scale of global warming driven by greenhouse gas emissions, and is prompting discussion about the pace of climate change and the urgency of cutting emissions.
- 2Uranium cubes show Nazi Germany had no path to atomic bomb●Nazi Germany had no hope of making an atomic bomb, uranium cubes reveal
New analysis of surviving uranium cubes from Germany's wartime nuclear program indicates Nazi scientists were far from building an atomic bomb. The findings, reported by Science, suggest the German effort never came close to the critical mass of fissile material needed, reinforcing historians' view that the project lagged far behind the Manhattan Project.
- 3How bad AI doomerism science serves big business▼How the bad science of AI doomerism is good for big business
The Bulletin of the Atomic Scientists has published an essay arguing that alarmist claims about existential AI risk rest on poor science while conveniently benefiting major tech companies. The piece contends that doomer narratives can justify regulatory barriers that entrench incumbents and distract from concrete present-day harms. Readers are debating whether catastrophic AI warnings are sincere, mistaken, or useful cover for corporate interests.
- 4"Atomic Cannon" Experiment Could Challenge Einstein's Theory of Gravity●This “Atomic Cannon” Could Challenge Einstein’s Theory of Gravity
Scientists are promoting a proposed experiment, nicknamed the "atomic cannon," that would test gravity with unprecedented precision using atoms. If results deviate from predictions, it could reveal cracks in Einstein's general theory of relativity and point toward new physics. Coverage highlights the potential for a major shift in how physicists understand gravity.
- 5Bulletin of the Atomic Scientists calls AI doomerism bad science●Nuclear doomsday mag says, AI Doomerism is bad science
The Bulletin of the Atomic Scientists, the magazine behind the Doomsday Clock, argues that claims about artificial intelligence posing existential risks amount to bad science. The publication contends AI doomerism relies on speculation and analogies to nuclear weapons that do not hold up, and says the debate should be grounded in evidence rather than fear.

A research team in Hong Kong reports a quantum metrology advantage described as limitless, meaning measurement precision using quantum resources may improve beyond previously assumed bounds. The finding, highlighted by physics-focused media, could matter for ultra-precise sensing technologies such as atomic clocks and gravitational detectors. Details of the results and independent verification have not yet been widely reported.
- 7Hiroshima and Nagasaki lessons urged for AI governance●Hiroshima and Nagasaki disasters offer lesson for AI governance
Nikkei Asia argues that the atomic bombings of Hiroshima and Nagasaki hold a cautionary lesson for how the world governs artificial intelligence. The piece draws a parallel between humanity's delayed response to nuclear technology and the current race to manage AI risks, suggesting societies should build international safeguards before harm occurs rather than after.
