Marc Abrahams: A science award that makes you laugh, then think

Duration: 13:12

As founder of the Ig Nobel awards, Marc Abrahams explores the world’s most improbable research. In this thought-provoking (and occasionally side-splitting) talk, he tells stories of truly weird science — and makes the case that silliness is critical to boosting public interest in science.

Jeff Iliff: One more reason to get a good night’s sleep

Duration: 11:41

The brain uses a quarter of the body's entire energy supply, yet only accounts for about two percent of the body's mass. So how does this unique organ receive and, perhaps more importantly, rid itself of vital nutrients? New research suggests it has to do with sleep.

Laurel Braitman: Depressed dogs, cats with OCD — what animal madness means for us humans

Duration: 19:29

Behind those funny animal videos, sometimes, are oddly human-like problems. Laurel Braitman studies non-human animals who exhibit signs of mental health issues -- from compulsive bears to self-destructive rats to monkeys with unlikely friends. Braitman asks what we as humans can learn from watching animals cope with depression, sadness and other all-too-human problems.

Molly Stevens: A new way to grow bone

Duration: 14:52

What does it take to regrow bone in mass quantities? Typical bone regeneration — wherein bone is taken from a patient’s hip and grafted onto damaged bone elsewhere in the body — is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone’s innate ability to regenerate and produces vast quantities of bone tissue painlessly.

Fabian Oefner: Psychedelic science

Duration: 12:05

Swiss artist and photographer Fabian Oefner is on a mission to make eye-catching art from everyday science. In this charming talk, he shows off some recent psychedelic images, including photographs of crystals as they interact with soundwaves. And, in a live demo, he shows what really happens when you mix paint with magnetic liquid--or when you set fire to whiskey.

Stuart Firestein: The pursuit of ignorance

Duration: 18:33

What does real scientific work look like? As neuroscientist Stuart Firestein jokes: It looks a lot less like the scientific method and a lot more like "farting around … in the dark." In this witty talk, Firestein gets to the heart of science as it is really practiced and suggests that we should value what we don’t know — or “high-quality ignorance” — just as much as what we know.

Elizabeth Loftus: The fiction of memory

Duration: 17:36

Psychologist Elizabeth Loftus studies memories. More precisely, she studies false memories, when people either remember things that didn't happen or remember them differently from the way they really were. It's more common than you might think, and Loftus shares some startling stories and statistics, and raises some important ethical questions we should all remember to consider.

Andras Forgacs: Leather and meat without killing animals

Duration: 09:02

By 2050, it will take 100 billion land animals to provide the world's population with meat, dairy, eggs and leather goods. Maintaining this herd will take a huge, potentially unsustainable toll on the planet. What if there were a different way? In this eye-opening talk, tissue engineering advocate Andras Forgacs argues that biofabricating meat and leather is a civilized way to move past killing animals for hamburgers and handbags.

Marla Spivak: Why bees are disappearing

Duration: 15:57

Honeybees have thrived for 50 million years, each colony 40 to 50,000 individuals coordinated in amazing harmony. So why, seven years ago, did colonies start dying en masse? Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world’s crops. Could this incredible species be holding up a mirror for us?

Heather Barnett: What humans can learn from semi-intelligent slime

Duration: 12:11

Inspired by biological design and self-organizing systems, artist Heather Barnett co-creates with physarum polycephalum, a eukaryotic microorganism that lives in cool, moist areas. What can people learn from the semi-intelligent slime mold? Watch this talk to find out.
