Ukraine has announced a large-scale programme to build an 'army of robots', described by officials as a 'Manhattan Project for physical AI'. The initiative aims to develop autonomous ground and aerial systems at scale for battlefield use, drawing comparisons to the World War Two atomic research effort. The announcement has drawn international attention given Ukraine's ongoing war with Russia and the growing role of drones and robotics in modern combat.

Researchers have unveiled what is being described as the world's most accurate clock, a milestone in precision timekeeping. Details of the instrument's design and performance remain sparse in early coverage, but such clocks typically rely on optical atomic transitions to keep time with errors of less than a second over the age of the universe.

Military.com reports that fewer than ten American veterans who witnessed the aftermath of the atomic bombings of Hiroshima and Nagasaki remain alive, and their firsthand accounts are rapidly disappearing. As the last eyewitnesses of the only wartime use of nuclear weapons pass away, historians and families are racing to record their stories before this direct link to 1945 is lost.

Thales, Bull and the French Alternative Energies and Atomic Energy Commission (CEA) are working together on software for quantum computers intended for use by the French armed forces. The partnership highlights France's push to develop quantum technology for defence applications, and observers are sharing the news across French-language tech and science circles.

Physicists at a particle collider report a surprising result from experiments on primordial matter, the hot dense state thought to have filled the early universe. The finding, covered by Scientific American, is drawing attention from researchers and science enthusiasts, though details of what exactly was observed and its implications remain limited in the initial reports.

Theoretical physicists, encouraged by recent progress in understanding black holes, are now applying the same tools to entire universes. Writing for Quanta, physicist Matt von Hippel explains how what they are finding is leading researchers to question fundamental assumptions about physics and cosmology.

Scientific American's latest science roundup covers the rising energy demands of artificial intelligence, ongoing efforts to detect subatomic particles, and research into an amoeba that thrives at extreme temperatures. The episode ties together the environmental cost of the AI boom with fundamental physics and biology discoveries, offering a snapshot of current conversations across science news.

French technology group Thales, computer maker Bull and the Alternative Energies and Atomic Energy Commission (CEA) are working together on software for quantum computers intended for use by the French armed forces. The collaboration links France's leading defence electronics firm, its flagship computing company and its national nuclear research body around military applications of quantum technology.

Sebastian Hassinger, host of The New Quantum Era podcast, argues that neutral-atom platforms currently hold the lead among quantum computing qubit technologies. He points to the approach's combination of scalability, long coherence times and flexible connectivity as reasons it is outpacing rival architectures such as superconducting and trapped-ion systems, at least for now.

Researchers at the International Center for Nanoarchitectonics report guiding quantum vortices using atomic-scale rails, offering a new way to control vortex motion in quantum materials. The approach could inform future work on superconductors and quantum devices, though detailed results and independent reaction to the findings remain limited so far.

Chemists report that the beta-silicon effect enables direct hydrogen atom transfer (HAT) for enantioconvergent couplings of alpha-silyl alcohols. The finding means two different alcohol-derived fragments can be joined efficiently into a single enantioenriched product, a long-standing challenge in synthesis, with the silicon atom steering the reaction pathway. Researchers say the approach could simplify how complex chiral molecules, including potential drug candidates, are built from readily available alcohol starting materials.

Researchers report generating quasicrystalline patterns in water waves, bringing the geometry famously seen in solid materials into fluid dynamics. Work on quasicrystals earned the 2011 Nobel Prize in Chemistry, and reproducing their aperiodic order in waves rather than atomic lattices is a striking demonstration. Physicists are discussing what the finding reveals about wave interference and whether similar ordered-but-non-repeating structures could emerge in other fluid systems.

A spokesperson for Iran's Islamic Revolutionary Guard Corps has rejected allegations that Tehran is pursuing nuclear weapons, calling the claim 'the lie of the century'. The statement, carried by international outlets, reasserts Iran's long-standing position that its nuclear programme is peaceful amid ongoing international scrutiny and tensions over its atomic activities.

Russian watchmaker Konstantin Chaykin has created a new piece inspired by the Left and Right Twins, the robotic ballerina characters from the video game Atomic Heart. The project translates the game's retro-futuristic robot design into a horological object, drawing attention from both watch collectors and gaming fans interested in crossovers between the two worlds.

Japan's Defense Minister Shinjiro Koizumi is calling for an open national debate on nuclear issues, including the possibility of nuclear-powered submarines. Any move to discuss nuclear options marks a highly sensitive shift in Japan, the only country to have suffered atomic bombings, where postwar policy has long adhered to the three non-nuclear principles. The proposal is drawing attention to how far Tokyo's security debate may go amid regional tensions.
