Public research university in Riverside, California, part of the University of California system, known for research across sciences and engineering.
Counties that once had a sundown town show higher implicit and explicit racial bias in a UC Riverside preprint of more than 1.3 million white participants. The authors do not claim the towns caused the difference.

Rocks from South Africa point to an ocean phosphorus loop that helped hold oxygen high about 2.3 billion years ago, researchers report in Nature Communications. The case rests on a method that separates usable phosphorus from locked-up phosphorus in old rock.
Reality
UC Riverside simulations find an Earth-mass planet could orbit stably in the habitable zone of 70 Ophiuchi's larger star, about 5 parsecs away. A stable orbit is the first test a habitable world must pass, so the result tells planet hunters where in this pair to look.
Reality
UC Riverside's Andrey Bekker and colleagues tie oxygen's persistence after the Great Oxidation Event 2.3 billion years ago to recycled phosphorus. If that loop held oxygen up for long stretches, something besides scarce oxygen may have slowed the rise of complex life.
Reality
A woman buried face down in a Henan cemetery had her nasal bones cut back to half the bridge and lived, and the team that found her among 300 burials argues the grave itself points to punishment.
Reality
Stephen Kane checked his tidal code against the measured Earth-Moon system, then ran Venus with moons of half to ten lunar masses, and most of those runs ended with the moon on the surface. Whether Venus ever had one remains open.
Reality
The insect growth regulator blocks the new exoskeleton a molting termite cannot do without. UC Riverside measured mortality in laboratory feeding tests, and the release summary reports the same figure as colonies killed.
Reality
Stephen Kane let hypothetical moons evolve around a Venus that turns once every 243 Earth days, and in most runs they spiralled inward and hit the planet. He says Venus needed no catastrophe to end up moonless.

A UC Riverside team matched 141 fires that reached American cities since 1984 against income, tenure and climate data, and found exposure concentrated in owner-occupied suburbs that also recovered their vegetation fastest.
Reality
Arctic ice drifts and spreads in ways wind-driven models get wrong. A UC Riverside-led team reports that floe-on-floe collisions, with one weakly constraining fitted parameter, reproduce three of those measured discrepancies at once.
Reality
The Environmental Protection Network says 17 of those actions name AI or data centers outright, and the remedy it proposes is a voluntary pledge for the White House to sign. The health figures it cites come from academic modelling.
Reality
The fight over data center water is argued in milliliters per query, while the most cited US projection says the deciding variables are which plant fills the power contract and which basin the campus sits in.
Reality
Gareth Funning and Axel Periollat map where subduction faults are locked rather than when they will break, and their algorithm marked the Kamchatka segment that later failed, working from what one author calls a relatively limited data set.
Reality
UC Riverside chemists tracked Criegee intermediates as ozone attacked isoprene, replacing inference from leftover products with measured kinetics. The rate constants themselves are not yet public.
Reality
UC Riverside watched Argentine ant colonies through glass after dosing them with two common bait chemicals. Each one produces a different, misleading visual signal.
Reality
Both fatalities disclosed so far came out of China's investigator-initiated trial route, the lightest-touch pathway in the field. US lawmakers were pushing to copy parts of it in June.
Reality
A Guardian investigation puts numbers on a gap every buyer of cloud capacity should assume exists: announced gigawatts and installed accelerators are not the same asset.
