Influenza A virus (IAV) possesses a segmented, negative-sense RNA genome comprising eight distinct viral RNA (vRNA) segments. These segments form ribonucleoprotein (RNP) complexes that are selectively ...

For decades, scientists have recognized that human immunodeficiency virus (HIV) is a formidable viral pathogen. After years of probing work and extensive experimentation, a Yale research team has ...

A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells ...

Bacteriophages, or phages for short, are viruses that infect bacteria. Using phages therapeutically could be very useful in fighting antibiotic-resistant pathogens, but the molecular interactions ...

There is currently no cure for HIV, but medications can help people with the disease manage their symptoms. HIV can still develop into AIDS years after infection, however, even with disease management ...

Researchers at Cima Universidad de Navarra have discovered that a ribonucleic acid that does not contain information to make proteins (long non-coding RNA) plays a crucial role in signalling and ...

The cold season is in full swing, throats are scratchy and noses are running. We feel ill and hope it is not the flu. The ...

Orthohantaviruses, such as the Puumala virus, are widespread in Europe, causing flu-like illnesses and severe kidney damage in those infected. It is increasingly considered a zoonotic threat.

RNA molecules carry instructions from DNA for making proteins that carry out much of the work of living cells. Knowing where these molecules are located in complex tissues is a critical part of ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
