Segments in this Video

Discussing Extinction (02:32)

FREE PREVIEW

The Pyrenean Ibex is the only species to have gone extinct—twice. Dara O'Briain introduces expert panelists on Science Club and outlines the topic of species loss.

Understanding Extinction (01:18)

Panelists show a trilobite fossil and explain the natural process of species loss.

Historical View of Extinction (03:50)

Learn how Biblical beliefs developed into an understanding of geological time through fossil evidence and evolutionary theory. Scientists discovered periods of mass extinction, including one occurring now.

Frog Killer (05:34)

Up to 99% of species have been lost during mass extinctions. Learn how the African clawed toad carries a fungus responsible for 40% of amphibians becoming endangered.

Habitat Loss (02:02)

Learn how increased global meat demand is responsible for species extinctions.

Lab Grown Beef (05:45)

At the University of Maastrict, researchers grow bovine muscle cells from stem cells. Learn how the process works and witness a scientific taste test.

Food Science Breakthrough (01:53)

Although in the proof of concept stage, scientists hope that lab cultured beef can be scaled up for industrial meat production.

Species Saving Ethics (01:58)

Alok Jha investigates whether Giant Pandas are worth the costs of keeping them alive. Learn about the endangered species' reproductive and eating habits.

Conservation Efficiency (01:27)

The London Zoological Society is attempting to prioritize endangered species by evolutionary distinction to maintain a wide gene pool.

Bee Decline (02:18)

Learn the importance of pollinators in food production and ecosystem function. Species extinction would have devastating effects, compared to pandas—but the conservation "poster child" helps spread awareness.

Conservation Debate (02:49)

Panelists argue for saving endangered species with key ecosystem functions, rather than charismatic mega fauna.

Human Extinction Threat (02:37)

Mark Steel visits Berlin to learn about an asteroid that could potentially hit Earth in 2036.

Near Earth Object Shield (02:27)

A physicist uses a billiards table to illustrate how space technology can deflect an asteroid from striking earth.

Reconstructing a Comet (05:06)

Learn the difference between asteroids, meteorites and comets. A scientist recreates a comet in the studio using carbon, dry ice, amino acids, and ethanol.

Genetic Arc Project (02:29)

Dr. Helen Czerski reports from New Orleans, where endangered species DNA is preserved and used to create embryos through IVF fertilization.

Resurrecting Extinct Species (03:23)

Learn how an African blackfooted wildcat embryo was implanted in a domestic cat, through interspecies surrogacy. Cloning by inserting DNA into embryos of other species is another method under study.

Resurrecting a Wooly Mammoth (01:43)

Panelists discuss the possibility of using DNA to bring extinct species back to life. O'Briain thanks guests on the show.

Description

Combining in-depth studio discussion with exploratory films and on-the-spot reports, Dara O Briain's Science Club takes a single subject each week and examines it from unexpected angles. In the third episode, comedian Mark Steel learns how to deflect an incoming asteroid, neuroscientist Tali Sharot tastes beef grown in the lab, Alok Jha examines whether it makes sense to conserve pandas, and Dr. Helen Czerski reports on experiments to bring back species from extinction. (50 minutes)
