Kary Mullis won the Nobel Prize in Chemistry for developing a way to copy a strand of DNA. (His technique, called PCR, jump-started the 1990s' biorevolution.) He's known for his wide-ranging interests -- and strong opinions.
Barry Schuler's multimedia firm Medior built key interactive technologies for AOL, helping millions connect to the Internet through a simple, accessible interface. Now, through venture capital (and wine appreciation), he wants to do the same for genomics.
Jack Horner and his dig teams have discovered the first evidence of parental care in dinosaurs, extensive nesting grounds, evidence of dinosaur herds, and the world’s first dinosaur embryos. He's now exploring how to build a dinosaur.
Dr. Gregory Stock's levelheaded look at the hotpoints where tech and ethics connect (or short circuit) have made him a popular guest on TV and radio. He directs the Program on Science, Technology, and Society at UCLA.
Surely not the only science career based on a museum tour epiphany, Paul Sereno's is almost certainly the most triumphant. He's dug up dinosaurs on five continents -- and discovered the world's largest crocodile, the (extinct) 40-foot Sarchosuchus.
Richard Preston wrote The Hot Zone, a classic look at the Ebola virus and the scientists who fight it. His wide-ranging curiosity about science and people has led him to cover a dizzying list of topics, with a lapidary attention to detail and an ear for the human voice.
It's relatively easy to imagine a new medicine -- the hard part is testing it, and that can delay promising new cures for years. In this well-explained talk, Geraldine Hamilton shows how her lab creates organs and body parts on a chip, simple structures with all the pieces essential to testing new medications -- perhaps even custom cures made fo...
Plants behave in some oddly intelligent ways: fighting predators, maximizing food opportunities ... But can we think of them as actually having a form of intelligence of their own? Italian botanist Stefano Mancuso presents intriguing evidence.
Have you confused a bee with a wasp, or an ant with a termite? Are all bugs the same to you? Zoologist Melinda Babits aims to change your mind. Babits' insightful research on insect behavior suggests that bugs are creatures with distinct personalities — and that studying their conduct might teach us a thing or two about human interaction.
As a collector of pinball machines, neuroscientist and psychologist Daniel Krawczyk has received his share of the sideways glances. In this eye-opening talk, however, he argues that collecting is a hardwired human behavior as a potent mix of neurobiology and social psychology.
In 2018, biomolecular archaeologist Ian Barnes' team at the Natural History Museum in London ascertained that Cheddar Man—the oldest near-complete human skeleton discovered in the British Isles—had dark skin and light eyes. Their findings challenged the views that many groups had long held about Britain's racial heritage. In this talk, Barnes de...
How do we search for alien life if it's nothing like the life that we know? Christoph Adami shows how he uses his research into artificial life -- self-replicating computer programs -- to find a signature, a "biomarker," that is free of our preconceptions of what life is.
Biologist Sara Lewis has spent the past 20 years getting to the bottom of the magic and wonder of fireflies. In this charming talk, she tells us how and why the beetles produce their silent sparks, what happens when two fireflies have sex, and why one group of females is known as the firefly vampire. (It's not pretty.) Find out more astonishing ...
