Nobel week: light-switched neurons, IceCube’s neutrinos, mirror-image molecules
The physiology or medicine prize honoured optogenetics, the control of neurons with light, a field Ars traces back to light-seeking algae. Physics went to Francis Halzen of the University of Wisconsin-Madison, who led development of the IceCube Neutrino Observatory. Chemistry rewarded work on how life’s ‘handed’, mirror-image organic molecules can emerge.

AI and mathematics: a flood of preprints and a race to beat the machine
OpenAI used an unreleased model to tackle hundreds of high-profile problems and posted around 700 maths preprints, prompting an angry response from mathematicians, according to Nature. Quanta described a field facing the shift with grief and anger, and told how three computer scientists rushed to publish a Unique Games milestone in the shadow of a rumoured AI proof. Science reported an AI that found solutions hiding in plain sight for problems in 22 scientific fields.
Nuclear clocks tick for the first time
Two Nature papers report working optical clocks based on the thorium-229 nuclear transition. In one, a team at TU Wien locked a continuous-wave laser to the 148-nanometre transition in thorium nuclei embedded in a calcium fluoride crystal, compared it with an ytterbium-ion clock, and used it to constrain models of ultralight dark matter. Nature’s commentary calls such clocks promising as a next-generation time standard.
Spaceflight: Crew-12 home, a Martian-moon heist, a UAE asteroid probe
NASA’s SpaceX Crew-12 splashed down off California on 8 October after 237 days in space and more than 100 million miles. Science previewed Japan’s mission to bring home pieces of a Martian moon, with NASA briefing on its contributions on 15 October. The UAE completed the Arab world’s first solo space probe, bound for an asteroid, and NASA released a trove of Moon data from Artemis II.
Margaret Hamilton, who wrote Apollo’s code, has died
Margaret Hamilton, whose code saved the Apollo 11 Moon landing, has died. Ars notes she also coined the term “software engineering” and founded two software companies, and the NYT recalled her work before computer science became a boys’ club.
Deep human past: Neanderthal tools in Spanish stone, an older Homo erectus
Neanderthal wooden tools from Spain survived as casts after dissolved rock precipitated around them before the wood decayed. Eighteen hominin fossils from Drimolen Cave in South Africa include a Homo erectus skull fragment dated to about two million years ago, roughly 200,000 years earlier than long thought for the region. Nature papers traced vanishing gut microbes that travelled with prehistoric humans, and a Jurassic mammaliaform suggesting suckling emerged in a common ancestor of mammals.
Building a mammal, cell by cell
Two teams mapped the development of mammal embryos cell by cell, Science reported. Nature described how gene-editing tools let researchers trace a single fertilised mouse egg to a late-stage embryo, alongside a paper on human heart development and its disruption in trisomy 21.
Earth in flux: a hole in Antarctic sea ice, Kīlauea’s fountains, a quiet Atlantic
An unprecedented opening the size of Portugal stayed ice-free in Antarctic winter sea ice, helped by atmospheric rivers. Before Kīlauea’s lava fountains began, the ground was rising by half a metre a day, and Ars and Phys.org explained how summit swelling helps forecast eruptions. An exceptionally quiet Atlantic season finally looked set to produce a hurricane, and Nature linked Australia’s worsening fires to colonial suppression of Indigenous burning.

US science policy: a $100,000 charge, NIH squeezes, a bigger Genesis Mission
A proposed US rule would charge international students $100,000 to do post-graduate work, which policy specialists say would choke off a STEM talent pipeline. NIH ended its fiscal year with a boost for early-career researchers but fewer new awards overall, and revived a network for emerging diseases with restrictions that baffle scientists. The Energy Department expanded its AI-focused Genesis Mission with larger grants, and US crop genome sequencing got $180 million.
Also this week
Nature unpacked unverified rumours around the death of a Siberian lab technician and what Russia won’t say about a plague scare. A common gut microbe secretes a molecule that lowers cholesterol production in mice. Modelling suggests the Solar System’s planetary orbits could destabilise within a billion years once the Sun starts shedding mass, and physicists entangled a suspended glass bead with light.
