An interview with Dr. Michael McIntosh, who discovered the drug Prialt while working as an undergraduate in Dr. Olivera's lab.
What medical secrets do venomous snails hold? How can listening in on bacterial conversations help develop new antibiotics? In four presentations, Dr. Bonnie L. Bassler and Dr. Baldomero M. Olivera reveal how a deeper understanding of nature and biodiversity informs their research into new...
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 ten-minute Q&A session, Dr. Olivera answers questions on cone snail behavior, venoms, and biodiversity.
Explore principles of taxonomy by sorting seashells according to their morphological characteristics and constructing an evolutionary tree.
Explore the biology of the symbiotic relationship between the Hawaiian Bobtail squid and bioluminescent bacteria Vibrio fischeri.
Understand how quorum sensing works by reasoning through experiments involving genetically-engineered bioluminescent bacteria.
Construct evolutionary trees by sorting seashells. To accompany the lecture series Exploring Biodiversity: The Search for New Medicines and the Sorting Seashells Click and Learn interactive.
A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It details the importance of foraminifera, known as "forams" for short, in discovering significant changes in Earth's past.
A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It shows the different organisms and metabolic diversity that results in a miniature model called a Winogradsky column.
The poster from the 2011 Holiday Lectures on Science, Bones, Stones and Genes: The Origin of Modern Humans. It provides a unique look at the classic "tree of life" and features a timeline of various hominid fossils and their stone tool usage.
The poster from the 2010 Holiday Lectures, Viral Outbreak: The Science of Emerging Disease, illustrating the size, geometry, and different classifications of viruses.
The following classroom-ready resources complement The Origin of Species: The Beak of the Finch. By following four decades of research on the finches of the Galápagos islands, the film illustrates how geography and ecology can drive the evolution of new species.
The following classroom-ready resources complement The Origin of Species: Lizards in an Evolutionary Tree. Research on the anole lizards is enriching our understanding of evolutionary processes, such as adaptation by natural selection, convergent evolution, and the formation of new...
The golden birdwing provided a striking clue to the natural origin of species.
This classroom experiment supports the film The Origin of Species: The Beak of the Finch. Students collect and analyze data to learn why even slight variations in beak size can make the difference between life and death.
Infant lemurs hitch a ride through the forest by holding on to their mother’s tummy or riding piggyback.
The bill of the buff-tailed sicklebill hummingbird is perfectly shaped to collect nectar from deep within the Centropogon flower.
The Lizard Evolution Virtual Lab was developed by a team of scientists, educators, graphic artists, and film makers to explore the evolution of the anole lizards in the Caribbean.
Set against the restoration of war-torn Gorongosa National Park in Mozambique, The Guide tells the story of a young man from the local community who discovers a passion for science after meeting world-renowned biologist E.O. Wilson.
Are we witnessing a sixth mass extinction? What factors threaten ecosystems on land and in the sea? What are researchers doing to try to conserve biodiversity and ecosystems?
