Sustainability of cattle bacteria tripled since 2000

The continued increase in the use of antibiotics for livestock has significantly increased resistance to pathogenic bacteria, according to a study conducted in Princeton, ETH Zurich and the Free University of Brussels. Researchers found that, especially in low- and middle-income countries, resistance to pathogenic bacteria in animals to antibiotics almost tripled between 2000 and 2018. […]

Flies can become genetically modified to become poisonous to predators

Using the CRISPR technique, a group of researchers from the University of California at Berkeley genetically modified some specimens of fruit flies (Drosophila melanogaster) so that they could obtain a significant advantage over its predators, one of those advantages that are usually acquired after thousands of years of evolution. The researcher Noah Whiteman, together with […]
