- ScienceDaily · Aparato digestivoEn inglésScientists discover how gut bacteria “train” the intestine to fight inflammationA compound made when gut bacteria break down dietary fiber may do more than briefly calm inflammation—it could leave a lasting protective “memory” in the gut. Northwestern Medicine researchers found that butyrate can reprogram intestinal lining cells so they continue encouraging anti-inflammatory immune responses even after the compound is gone. In mice, this effect boosted production of the immu…

- ScienceDaily · MicrobiotaEn inglésWhy South Africa’s leopards shrank to half their normal sizeA hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after being isolated for roughly 20,000 years. Surprisingly, despite their small population, they have retained much of their…
- ScienceDaily · MicrobiotaEn inglésOne tiny mutation may explain how bat viruses become human threatsScientists found that one tiny genetic change can completely alter how a coronavirus behaves in different species. Comparing SARS-CoV-2 with a closely related bat-only virus, they showed that a single amino-acid difference affects whether the immune system fights back or gets suppressed. This may help explain how some animal viruses make the leap to humans and become far more dangerous.
