Helen Lazear, Ph.D., associate professor of microbiology and immunology, and Qi Zhang, Ph.D., professor of biochemistry and biophysics, have discovered that a type of RNA in Zika virus ...

Researchers have shown, for the first time, how the genetic material of the Nipah virus replicates in infected cells. The ...

Mongolia has recorded 24 new cases of measles infection over the past 24 hours, bringing the national caseload to 51, ...

Endogenous retroviruses, ancient viruses embedded throughout mammalian genomes, might help RNA viruses permanently integrate into the genomes of their hosts ...

Viruses, then, may have existed before bacteria, archaea, or eukaryotes (Figure 4; Prangishvili et al. 2006). Most biologists now agree that the very first replicating molecules consisted of RNA ...

This is SARS-CoV-2, the virus that causes COVID-19. It's a type of RNA virus, some of which mutate practically every time they replicate. SARS-CoV-2 is actually one of the rare RNA viruses that ...

Periodically, the yearly flu transforms into a particularly virulent strain, like the Spanish flu that killed millions of people in 1918. How do these pandemic strains arise? Aa Aa Aa Although ...

It is a near sphere of protein (cross section shown) inside a fatty membrane that protects a twisting strand of RNA--a molecule that holds the virus's genetic code. Proteins called "S" form spikes ...

Maternal hepatitis C virus (HCV) RNA titer > 10⁶ International Units (IU)/mL and antepartum bleeding are key predictors of perinatal transmission, with the risk ranging from 1.5% to 28.5%. The ...
