Public research university in San Diego, part of the University of California system, noted for engineering, physics, and public health research.
A study with UC San Diego co-authors scanned 114 adults with chronic back pain after a provoked flare and saw default mode network activity rise. An outside neuroscientist praised the design but said lingering pain or anxiety could also explain the signal.
Reality
UC San Diego-led researchers report perovskite solar cells and LEDs at around 24% to 26% efficiency, grown with a temporary liquid phase. In the one durability result the report describes, the solar cells kept most of their efficiency through eight weeks of simulated sunlight.
Reality
UC San Diego and Toyota researchers built a fluorine-free battery binder that dissolves in water, so electrode coatings come off their foils with a soak. For a cell maker, the first payoff is on the production line, where water replaces toxic solvents.
Reality
Michael Perry's UC San Diego lab found the genetic switch behind the butterfly's ninth light-detecting cell per eye unit and rebuilt it in fruit flies. The flies' brains wired the extra cell to spare neurons they would normally discard, so the change to the eye was enough on its own.
Reality
People in a Wharton-led study set the smallest worthwhile gift about 70% above what recipients would accept, so many holding only a small sum gave nothing. For anyone running a giving drive, the authors' field test shows a lower ask brings in more contributors while pulling gifts down toward the amount asked.
Reality
Of 37 artificial structures placed in Kane'ohe Bay, Scripps-led trials found coral larvae settled most on those nearest a speaker playing healthy-reef sound. The result puts sound beside living coatings and 3D-printed surfaces as a restoration tool, so far tested in a single Hawaiian bay.
Reality
Connor Dalby, who had tried 12 or 13 anti-seizure drugs, took unassisted steps about four months after starting a drug built for his SCN2A mutation. His case, now in Nature Medicine, is a single patient, so how often made-to-order drugs like his work is still unknown.
Reality
Merriam-Webster added at least six AI and computing terms, including 'agentic' and 'vibe coding', to its online dictionary in September. The entries show that specialist AI terms now circulate in mainstream print, but the dictionary's method cannot tell how many general readers understand them.
Reality
UC San Diego physicists compared eight Planck polarization maps against each other and recovered the same 0.37-degree twist as the standard analysis. The agreement gives cosmologists a second way to ask whether the rotation is in the sky or in the instrument, though the authors stress it does not confirm the twist is real.
Reality
UC San Diego and Inria researchers forged a 1024-bit RSA signature through an HSM in 1,380 core-years, against at least 500,000 to factor the key. The attack only works with raw, unpadded signing access, so how exposed a custodian is depends on how its HSM is configured.
Reality
UC San Diego and INRIA researchers forged RSA signatures on a 1,024-bit key inside a hardware security module after about 4 billion signing requests. The key stayed inside the device throughout, so for custodians the exposure is in signing settings, starting with the FIPS mode the researchers switched off.
Reality
Academic researchers hijacked the link between two Boeing 737 flight computers with a coin-sized board. The constraint was never budget or code. It was who can reach the nose bay.
Reality
A UC San Diego lab measured expression across about 500,000 initiator variants and fit a model to the result. The prevalence headline is the least useful part of it.
Reality
UC San Diego and Inria researchers report an attack, not yet peer reviewed, that cuts textbook RSA-2048 from 2^112 to 2^90 operations. It needs billions of queries against a raw RSA private key, so unmonitored HSMs and key-management services are the first place to look.
Reality
UC San Diego physicists cross-checked eight Planck polarization maps and found their relative calibration matches the standard analysis. The test cancels any rotation all detectors share, so the hinted 0.37-degree twist still needs an absolute angle reference.
Reality
A UC San Diego team imaged thousands of neurons in transparent 12-millimetre fish watching computer-generated schools, and found midbrain cells that treat a partner's sudden absence much as they treat a partner's flight.
Reality
High-harmonic X-ray sources normally emit only at integer multiples of their driving laser. A TU Wien and UC San Diego method detunes the driver instead, filling in the frequencies between two neighbouring harmonics.
Reality
UC San Diego researchers treated cancer cells with 25 mitochondria-perturbing compounds, collected 40,000 single-cell 4D movies, and trained a model that sorted the drugs by mechanism with the labels withheld.
Reality
A five-year, $3.3 million project led at Worcester Polytechnic Institute will test whether the biology that builds sea sponge skeletons can break silicon-rich industrial waste apart gently enough to free the minerals inside.
Reality
For years, dog cognition mostly asked owners what their dogs were like. Rossano's soundboard project and two newer studies measure the dogs instead, though the published account is short on samples and controls.
