Microbiologist Bonnie Bassler wins Royal Society’s Copley Medal

Microbiologist Bonnie Bassler has been awarded the 2026 Royal Society’s Copley Medal, the world’s oldest and most prestigious scientific prize.

Bassler, a professor at Princeton University, is celebrated for her revolutionary discovery of "quorum sensing."

Her research fundamentally changed our understanding of microbiology by proving that bacteria are not solitary, antisocial organisms.

Instead, she demonstrated that they communicate using chemical signals to coordinate collective behavior, much like a multicellular society.

This discovery is not just theoretically significant; it has paved the way for new medical strategies.

By "jamming" these bacterial communication signals, scientists are developing novel treatments to combat drug-resistant pathogens, offering a promising alternative to traditional antibiotics.

Beyond her scientific accolades, Bassler is a staunch advocate for diversity in STEM.

This latest honor confirms her place among the most influential scientists of our time, bridging the gap between fundamental biological inquiry and vital breakthroughs for human health.
