What researchers actually found inside 100 South Australian rainwater tanks
The tests found bacterial DNA and occasional elevated metals, but a genetic signal, a living organism and a demonstrated illness are not the same finding.
technology
This prosthetic socket hides motion sensors beneath its carbon-fiber shell
A four-person study shows how protected sensors can be built into a socket—and why successful fabrication is not yet proof of better care.
world
The US proposed an AI incident channel with China. Six missing pieces will determine what it does
The September 20 talks produced an idea, not an operating crisis line—and the difference lies in its institutional details.
nature
A few milligrams of enamel became a thermometer for T. rex
Temperature-sensitive bonds in three fossil teeth produced an estimate of 36.3°C, while five crocodilian teeth helped test whether burial had rewritten the signal.
nature
Inch-long sand hoppers move 38 kilograms of beach per metre overnight
Researchers weighed fresh burrow mounds, then used hopper biomass to model a much larger—but carefully bounded—single-day estimate.
science
A tiny shift in iron’s X-rays reveals a stellar wind falling onto a pulsar
XRISM turned a displacement of only a few electronvolts into a measurement of otherwise invisible plasma racing toward a neutron star.

360-degree video catches AI scene models losing track
PersistBench uses a second view of the same moment to test whether dynamic-scene models preserve an object’s existence, motion and appearance after it leaves the frame.

science
Red blood cells adapt to low oxygen by rearranging what they already have
Experiments reveal an oxygen-sensitive switch around the membrane protein Band 3 that redirects existing cellular machinery without making anything new.
science
Study finds adults’ chosen task information outperformed random selection
An experiment suggests that useful knowledge accumulates more effectively when adults choose what to pass on, rather than merely sending along information.
science
What Hurricane Hunters see as a tilted cyclone lines up
Aircraft radar reveals four characteristics associated with vertical alignment, an important step in intensification—but not a guarantee or a validated forecast checklist.
science
Hiding some evolutionary clues helped AlphaFold 3 find missing protein shapes
A benchmark of 107 proteins found that selectively weakening AlphaFold 3’s evolutionary input sometimes exposed experimentally observed conformations that ordinary predictions missed.
technology
How a 44-gram drone feels its way past transparent walls
Two flexible whiskers turn gentle contact into an estimate of a surface’s forward distance, helping an experimental drone navigate when optical sensing becomes unreliable.
technology
A Gemini security test reached three real companies. The boundary failed first.
The alarming episode shows why AI-safety claims must be judged alongside network controls, target checks, monitoring and the evidence made public afterward.

How an archaeon fixes nitrogen at about 92°C
A deep-sea microbe’s unusually heat-stable nitrogenase gives researchers a near-atomic view of the metal clusters that help break nitrogen’s stubborn triple bond.
nature
How one giant cell launches—and brakes—a millisecond contraction
Three studies divide Spirostomum’s roughly half-length contraction into a calcium-linked signal, a modeled mechanical response and a proposed internal damping system.
science
VIPR reads DNA with a ‘match two, skip one’ code
A peer-reviewed structural study reveals an RNA-guided recognition system that deliberately leaves every third DNA letter unmatched.
science
A stiff film slows heat better than silicone
A layered material combines the rigidity of a solid with unusually poor heat conduction, challenging a familiar materials tradeoff without yet proving a practical coating.
technology
AI is helping build AI. It has not yet closed the loop.
New measurements show AI writing research code and running experiments, while the crucial work of choosing goals, validating durable gains and producing a better successor remains unproven.
nature
On Okinawa, plastic has seeped into the pores of coral rubble
Lab instruments showed that bright specks on dead coral fragments were polyethylene and polypropylene embedded in the skeleton—not loose litter resting on it.

Japan’s deposit, loan and mortgage rates are moving at different speeds
Savings accounts now pay noticeably more, but official data and current bank offers show that borrowing costs have also climbed—and the rate on the page may not be the rate a customer receives.
technology
This DNA computer gets answers by settling down
Programmed DNA strands compete for places on a scaffold until the mixture favours an arrangement that encodes the result.

At least 112,000 displaced within Yemen in two weeks as nearly 3,000 reach Djibouti
Separate snapshots show a rapid internal displacement crisis and a smaller cross-border movement, each measured across a different place and reporting window.

Trenton’s data-center fight is headed to voters after a 336-signature dispute
After Ohio’s highest court rejected the city council’s 820-signature threshold, the council certified a proposed ban on large data centers for a November 3 special election.

Nanyin returned to China with sounds shaped in Singapore
A Fujian musical tradition carried by migrants to Singapore is being presented in Shanghai alongside relationships it acquired there—including Indian classical music and dance.
technology
Your coding AI is more than its model name
A controlled study found that memory, planning and tool design can materially change the success and cost of an AI coding assistant while its underlying model stays fixed.
science
To read a burned scroll, scientists made one to sacrifice
A modern papyrus with known writing showed how lead-sensitive X-rays and virtual unrolling might identify ancient texts worth scanning—without touching their brittle layers.
nature
When does helping a young chimpanzee become a lesson?
Two remarkable encounters in Senegal show how scientists can identify teaching by its effects without pretending to know exactly what an animal intended.
nature
The cat was never missing. Science’s name for it was.
A tiny Bolivian wild cat shows how one familiar-looking animal can conceal an ancient lineage—and why correcting the family tree matters.
science
The antimatter was the lightest part of the shipment
Ninety-two antiprotons crossed CERN inside an 850-kilogram machine—and a tiny electrical signal showed that every one survived.
nature
A carnivorous plant turns microbial wandering into one-way traffic
Genlisea’s underground traps appear to rectify the restless motion of microbes, moving prey and debris uphill without an obvious pump.

Polonius lets Rust skip an allocation the borrow checker used to demand
A nightly-only borrow-checker upgrade accepts the natural borrowed-key lookup-or-insert pattern, avoiding owned-key construction on cache hits.
