For 400 million years, a leading hypothesis claims, Earth was an “RNA World,” meaning that life must’ve first replicated from RNA before the arrival of proteins and DNA. Unfortunately, scientists have ...

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 ...

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life. Scientists ...

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 ...

Researchers show how LGP2 binds viral RNA ends, moves along the strand, and helps MDA5 form filaments that amplify antiviral signaling. The findings clarify an early defense step and may inform ...
