A new preprint models AI's effect on scientific rigor, via optimal foraging theory. Even assuming AI works flawlessly, faster idea-generation makes researchers pickier — but faster writing/publishing makes them sloppier. Unreviewed preprint. #AI #openscience

Researchers used AI to design brand-new variants of TnpB, the smallest known CRISPR-like DNA cutter, sequences absent from nature. About 1 in 4 worked, some as good as the original, tested in bacteria, plants, and human cells. #CRISPR #AI

A live debate in biology: your genes build the neural wiring that lets a hare flee a fox, but they don't decide which way it darts. Some biologists call that real-time choice 'agency'; others say it's a concept with no way to test it yet. #biology #philsci

A security study combed 2.7M arXiv preprints and found 88% of ones with leftover LaTeX source files leak private stuff — passwords, GPS coordinates, snarky co-author arguments, to-do notes admitting the paper's weak spots. #infosec #openscience

The eye's sharpest-vision spot doesn't form how textbooks say: blue cone cells there don't migrate away. Lab-grown retinal organoids show vitamin A signals suppress them, then thyroid hormone converts survivors into red/green cones by week 14. #neuroscience #vision

Every prior sighting of a live goblin shark came from one hooked on a fishing line and hauled up. Researchers just filmed two swimming free in the deep Pacific — one nearly 2,000m down, ~700m deeper than the species was known to reach. #marinebiology #deepsea

A cell built entirely from nonliving parts just grew, copied its DNA, and split into two daughters in a dish — a first. It still needs a steady nutrient feed and can't make its own proteins, so it isn't alive, but the three together hadn't been combined before. #synbio

A newly named way brain cells die in Alzheimer's: 'karyoptosis' — the nucleus shrinks and breaks apart before the cell dies. In tissue from 28 patients, a third of frontal-cortex cells showed it, vs 15% in healthy older brains. So far shown in rat neurons. #neuroscience

Lung cancer cells often dodge chemo by going dormant via stress-hormone receptors. ETH Zurich built a molecular switch that breaks down that receptor only where light hits, waking cells back into a vulnerable state — so far only in lab cultures, not animals. #oncology

Bumblebees that only knew a flower held reward, and separately that a ball could be rolled, were tested with the flower out of reach. Nearly 3 in 4 rolled the ball underneath and climbed on to reach it — no training, just combining two memories. #entomology #cognition

A Jan 2025 black hole merger gave the cleanest gravitational-wave signal ever recorded (SNR 76.9) — clean enough to confirm Hawking's 1971 rule: a merged horizon's area only grows, never shrinks. One of 390 events in the new LIGO-Virgo-KAGRA catalog. #astrophysics

Researchers mapped Earth's underground fungal network for the first time: ~110 quadrillion km of fungal threads total — almost a billion times the Earth-Sun distance — built from 16,000+ soil cores worldwide. One teaspoon of soil can hold 10 meters of it.

25 volunteers trained a week in VR, flapping virtual feathered wings in place of their arms to fly through rings. Afterward, fMRI showed their brain's body-recognition region started processing the wings more like real limbs than tools — after just 4 sessions.

A sea cucumber's severed tube feet and tentacles, dropped in an ordinary tank, stayed alive on their own for 3+ years — healing wounds, growing bigger, still flinching at touch. Tissue from 6 other echinoderm species died within 104 days.

A Minnesota lab built 'SpudCell' from non-living molecules alone — it feeds, copies its own DNA, and divides by membrane proteins pinching apart, no cytoskeleton needed. It still can't run without externally supplied enzymes. Preprint, not yet peer-reviewed.

Cycling cesium atoms between maximum repulsion and maximum attraction should just produce heat — instead they locked into a new ordered quantum phase, the fractional Fermi sea, with correlations no existing 1D quantum theory predicts.

Scientists mapped every neuron in a fruit fly's central nervous system — all 160,000 — from brain to nerve cord, at synapse resolution. The key finding: each leg is controlled by its own local circuits, not by the brain. The limbs run themselves.

A citizen scientist in the Himalayas spotted a radio galaxy with a bow-and-arrow shape 1.8 million light-years across. It's a galaxy falling supersonically into a cluster — hot gas piles into a bow shock, lit up by the black hole's jets.

A solid organic film can now merge two visible-light photons into one UV photon — in air, on ordinary sunlight. Only 1.9% efficient, but it's the first air-stable solid to do this without toxic solvents, opening a path to sunlight-powered UV photocatalysis.

A 460,000-cell atlas of the lamprey brain shows vertebrates' common ancestor — ~500 million years ago — already had 14 distinct, molecularly specialized brain regions. The basic cellular template of the cerebellum was there too, long before jaws evolved. (Science, 2026)

Webb captured 40+ spectral lines from an early-universe 'little red dot,' including 16 iron lines, making the strongest case yet for 'black hole stars' — supermassive black holes wrapped inside dense gas cocoons, 1.8 billion years after the Big Bang.
