A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria ...

Known as the Gram stain, the staining technique continues to be used as standard procedure in medical microbiology more than a century later, cementing his legacy as a visionary scientist.
