The University of California, Santa Cruz is a public research university known for strengths in astronomy, astrophysics, and marine and environmental sciences.
UC Santa Cruz researchers say the peptide P3, long thought harmless, can form clumps faster than amyloid beta and may damage brain cells. The claim comes from a commentary that highlights research, so P3's role in Alzheimer's disease is still a hypothesis.
Reality
UC Santa Cruz researchers used copepod alarm chemicals to forecast toxic mussels seven weeks ahead, against one week for models tracking the toxin itself. That long warning covered 22% of high-toxin events at a single Monterey Bay wharf, about one in five.
Reality
UC Santa Cruz and UCLA researchers found that new US mosques were 16% to 18% more likely than nearby new churches to face opposition, in a study of 107 pairs. The authors say parking complaints often mask anti-Muslim prejudice, an inference the paired design supports but cannot prove on its own.
Reality
Claudie Beaulieu's team fit statistical models at every grid point of 55 years of surface temperature data and found warming speedups arriving in separate regional waves, the most recent in midlatitudes such as southeast China.
Reality
A preprint led by UC Santa Cruz graduate student C. Evan Davis modelled Earth-like planets around M dwarfs of two ages. The star's ultraviolet output alone changed how much methane the atmospheres held by up to a factor of ten.
Reality
Stefano Profumo ran twelve dark matter scenarios through the Barbieri-Giudice sensitivity test in Physical Review D. A popular particle model tied to a Higgs resonance came out among the most fine-tuned of the set.
Reality
Three Yukon fossils and one from Wyoming place Miracinonyx trumani beside the puma rather than the cheetah. Nitrogen isotopes put the northern animals near the top of a fish food chain far above the old known range.

A Science Advances study traced surviving juveniles back to individual nests using ear-bone chemistry. Its own authors warn against the obvious operational use of the finding.
