Columbia and UC Berkeley researchers report in Nature that microplastics spontaneously generate reactive oxygen species in the water around them. The finding offers a chemical route to the tissue damage associated with microplastics, though the authors hedge on harm to people.

Animated films give female animals, monsters and robots about a quarter of nonhuman screen time
UC Berkeley researchers found female characters get about 25% of nonhuman screen time across 224 animated films, against close to half for human characters. On this measure the human share is near parity and the remaining imbalance sits among nonhumans.

Researchers propose a superfluid helium gyrometer to catch Earth's frame-dragging in a laboratory
UC Berkeley, Austrian Academy of Sciences and Caltech researchers propose a superfluid helium gyrometer to detect Earth's frame-dragging in a lab. The case rests on a new thermal-noise analysis, since random phases can swamp the signal.

buildConfirmed2 publishers Sakana AI and UC Berkeley's MASS method reached a 69.9% win rate against its Qwen3.6-27B base model after two rounds of self-training. The same model ranks its own runs, and its evaluator sometimes passes flawed steps into the next training set.

buildOne report1 publisher Berkeley statisticians find METR's time-horizon axis nearly flat between 2 and 30 minutes
Berkeley statisticians Nguyen and Fithian refit METR's time-horizon data and found AI task difficulty barely changes between 2 and 30 minutes of human time. Equal 10x steps on the plot therefore mean unequal capability gains, depending on where on the axis they fall.

Berkeley undergraduate proposes three isolated, quenched dwarf galaxies as backsplash candidates
Julian Shapiro, a UC Berkeley undergraduate, reports in The Astrophysical Journal three isolated dwarf galaxies that have stopped forming stars. He argues a large neighbor stripped them and threw them outward, but whether they are truly isolated still rests on distance estimates awaiting follow-up.

Eastern Sierra survey finds unhealthy pinyon stands where Paiute and Washoe members had flagged decline
UC Berkeley-led researchers found three Eastern Sierra areas with a high share of unhealthy pinyon-juniper trees, all where tribal members had seen decline. The match shows tribal reports pointed to the right stands, a guide for managers deciding where to monitor and thin.

OpenAI's claimed proof of a famous math problem starts a fight over authorship and standards
OpenAI said on September 8 that its models had solved one of mathematics' most famous problems, setting off a dispute over authorship and proof standards. The fight now turns on whether proofs that mathematicians can barely read can be checked and credited at all.

UC Berkeley researchers found chimpanzees stole pineapple in 61% of trials with friends and 70% with nonfriends. Friendship trimmed theft without stopping it, and the team argues both parties' emotional reactions show chimps expect better treatment from friends.

UC Berkeley turns 7 million pages of local ordinances into one free searchable database
UC Berkeley researchers turned roughly 7 million pages of local law from all 50 states into a free, searchable database. Comparing codes across towns becomes a search, run on text that an AI pipeline read and sorted.

Most Americans in a Berkeley experiment chose candidates and policies by one factor or a quick tally
UC Berkeley's Kirk Bansak and Nidhi Banavar report in PNAS that most of nearly 3,800 participants skipped weighing every attribute of political choices. Because every attribute was on screen, the result concerns how people use information they already hold.

Argon dating of Vesuvius sanidine lands within eight years of the eruption Pliny recorded
Berkeley and Padua researchers dated eight Vesuvius sanidine samples to 1,938 years, give or take 13, against the 1,946 years that Pliny's account implies. The same historical date helped make potassium-40's half-life, the constant under every argon-argon age, twice as precise.

Food executives fear pooled safety data could be used against them, Cornell interviews show
Cornell researchers who interviewed 27 food industry leaders found that trust, more than technology, keeps companies from pooling safety data for AI. The evidence is what executives told interviewers, so whether removing those barriers would free up the data is still an open question.

Trace lead in ink makes writing stand out in X-ray scans of papyrus burned on purpose
Douglas Seiler's team found lead-bearing ink absorbed up to 25 times more X-rays than charred papyrus, in test scrolls they wrote and burned themselves. How much that helps at Herculaneum depends on how many of the library's scrolls used lead ink, and nobody has counted yet.

Product managers still deliver stories, argues a former LinkedIn PM writing for a16z
An ex-LinkedIn product manager writing for a16z demotes the 120-page spec the author once wrote and names the story as a PM's most important output. AI changes how teams code, the author writes, but the story still has to survive being retold without the PM in the room.

Argon-argon dating of Vesuvius sanidine lands eight years from Pliny's eruption date
Berkeley and Padua geochronologists dated eight crystals from Vesuvius to 1,938 years, plus or minus 13, against a recorded age of 1,946 years. The same eruption date let them measure potassium-40's decay twice as precisely. Carbon-14 and uranium-lead results can now be checked against that constant.

Cooling minerals pull CO2 into Mojave soils every night, Berkeley researchers find
UC Berkeley researchers say Mojave soil minerals adsorb CO2 at night and release it by day, moving 1 to 3 gigatons of carbon a year if scaled globally. Part of the soil exchange long credited to microbes may be physical, though the global figure rests on Mojave soils alone.
