Venomous carniverous cone snails are a rich source of molecules for scientific research and potential drug development.
Bacteria are capable of communicating and coordinating their activities with a molecular signaling system called quorum sensing.
Cone snails have evolved many different toxins for different uses. Total molecular biodiversity may number in the millions.
The quorum sensing system is a target for a new class of drugs that interfere with virulence without killing bacteria.
A discussion on biodiversity, endangered habitats, and how best to preserve the Earth's ecosystems, presented by the lecturers along with Dr. E.O. Wilson and Dr. Eric Chivian.
In this 13-minute Q&A session, Dr. Bonnie Bassler answers questions on quorum sensing and other topics related to bacteria.
In this ten-minute Q&A session, Dr. Olivera answers questions on cone snail behavior, venoms, and biodiversity.
