Unlike animals, plants do not possess an adaptive immune system with antibodies or T cells to fight viral infections. Instead ...

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 ...

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 ...

The active ingredients have a broad spectrum effect; a series of RNA molecules support the plant's immune system in combating the virus. In laboratory experiments, 80 to 100% of the treated plants ...

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 ...

Arcturus Therapeutics Holdings Inc. (the "Company", "Arcturus", Nasdaq: ARCT), a commercial messenger RNA medicine company ...

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 ...

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 ...

Researchers have unveiled innovative, label-free ratiometric fluorosensor designed for the selective and sensitive detection of enteroviral RNA. The research promises to deliver even more advanced and ...

A federally funded project aims to determine how West Nile virus cycles through mosquitoes and the animals they bite.

New RNA-based active agents reliably protect plants against the Cucumber mosaic virus (CMV), the most common virus in agriculture and horticulture. They were developed by researchers at the Martin ...
