Richard Preston The mysterious lives of giant trees
Science writer Richard Preston talks about some of the most enormous living beings on the planet, the giant trees of the US Pacific Northwest. Growing from a tiny seed, they support vast ecosystems — and are still, largely, a mystery.
Rachel Sussman The world's oldest living things
Rachel Sussman shows photographs of the world's oldest continuously living organisms — from 2,000-year-old brain coral off Tobago's coast to an "underground forest" in South Africa that has lived since before the dawn of agriculture.
Jonathan Drori The beautiful tricks of flowers
In this visually dazzling talk, Jonathan Drori shows the extraordinary ways flowering plants — over a quarter million species — have evolved to attract insects to spread their pollen: growing 'landing-strips' to guide the insects in, shining in ultraviolet, building elaborate traps, and even mimicking other insects in heat.
Suzanne Simard How trees talk to each other
"A forest is much more than what you see," says ecologist Suzanne Simard. Her 30 years of research in Canadian forests have led to an astounding discovery — trees talk, often and over vast distances.

Antonio Donato Nobre The magic of the Amazon: A river that flows invisibly all around us
The Amazon River is like a heart, pumping water from the seas through it, and up into the atmosphere through 600 billion trees, which act like lungs. Clouds form, rain falls and the forest thrives. In a lyrical talk, Antonio Donato Nobre talks us through the interconnected systems of this region, and how they provide environmental services to the entire world. A parable for the extraordinary symphony that is nature.
Jill Farrant How we can make crops survive without water
As the world's population grows and the effects of climate change come into sharper relief, we'll have to feed more people using less arable land. Molecular biologist Jill Farrant studies a rare phenomenon that may help: "resurrection plants" — super-resilient plants that seemingly come back from the dead. Could they hold promise for growing food in our coming hotter, drier world?
Michael Pollan A plant's-eye view
What if human consciousness isn't the end-all and be-all of Darwinism? What if we are all just pawns in corn's clever strategy game to rule the Earth? Author Michael Pollan asks us to see the world from a plant's-eye view.
