A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the host proteins that the ...

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body’s defense ...

Viruses are entirely dependent on their hosts to reproduce. They ransack living cells for parts and energy and hijack the host's cellular machinery to make new copies of themselves. Herpes simplex ...

For the first time, scientists have been able to watch the flu virus live as it infects human airway cells. They developed a ...

New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn a deadly pathogen into a harmless bug or supercharge a relatively benign ...
