A team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific world. Developed from a derivative of the immune system of bacteria, CRISPR enables double strands of nucleotides in deoxyribonucleic acid (DNA) to be cut. This makes it possible to specifically modify a targeted gene in plant, animal and human cells. Ultimately, CRISPR became a preferred method in the search for treatments for acquired or hereditary diseases.

Like the dengue and Zika viruses, Oropouche virus causes a febrile illness. There are recent indications that infections during pregnancy can cause damage to unborn babies. Researchers have now determined that the virus is much more widespread in Latin America than previously assumed. Their study also suggests that climatic conditions have a significant influence on the virus's spread.
