This undated handout picture released by Cell Press on March 6, 2026 shows a Vesicular Stomatitis Virus (VSV) (elongated particle) and a rodent deltavirus. Microbes still hold surprises. Researchers have just discovered how tiny viruses slip inside other viruses to penetrate and infect a cell. 'Deltaviruses are transmitted via a viral Trojan horse,' according to a study published on March 6, 2026 in Cell, one of the most prestigious biology journals, led by researchers from the CNRS.
