Countries with More Cats Report Higher Happiness, Scientists Say | Sci.News (opens the original)
Read excerpt
New research led by the University of Chicago found that nations with more domestic cats tended to report higher levels of happiness, while greater exposure to Toxoplasma gondii, a neuroparasite associated with cats, was linked to lower scores. The study authors caution that the findings show associations, not cause and effect. Borráz-León et al. found that national happiness was positively associated with cat density and some socioeconomic factors. Image credit: Sci.News / Makieni777 / Rise-a-m
Sugar Molecule Made by Gut Bacterium Can Shrink Visceral Fat in Mice | Sci.News (opens the original)
Read excerpt
Clostridium immunis, a human gut bacterium, secretes a large sugar molecule that can shrink visceral fat and curb weight gain in mice, according to a paper published in the journal Cell Host & Microbe. Yee Tan et al. discovered a human commensal bacterium, Clostridium immunis, which prevents and treats obesity in mice by secreting a phosphocholine-modified exopolysaccharide (EPS). Image credit: Yee Tan et al., doi: 10.1016/j.chom.2026.08.018. “The global obesity epidemic continues to worsen, wit
Bats Originated in Europe, Genetic and Fossil Evidence Suggests | Sci.News (opens the original)
Read excerpt
Bats make up more than one fifth of all living mammal species, yet where and when they first took to the air has been debated for decades. An analysis of 103 bat genomes points to the European continent as the birthplace of the only mammals capable of powered flight, overturning earlier theories that favored Africa, Asia or North America. The findings come from the Bat1K consortium, an international effort to sequence the genomes of all living bat species. The first phase of the Bat1K project: 1
New Species of Tiger Cat Identified in Bolivia | Sci.News (opens the original)
Read excerpt
Scientists have demonstrated that the South American tiger cat complex Leopardus tigrinus consists of five genetically distinct species, including one entirely new to science. Leopardus tilcayo. Image credit: Paola Nogales-Ascarrunz. The Leopardus tigrinus species complex is a group of small, spotted felines found across Central and South America and known variously as tiger cats, little spotted cats, or tigrinas. Their subtle physical differences have made them notoriously difficult to classify
