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?

Aris Venetikidis Making sense of maps
Map designer Aris Venetikidis is fascinated by the maps we draw in our minds as we move around a city — less like street maps, more like schematics or wiring diagrams, abstract images of relationships between places. How can we learn from these mental maps to make better real ones? As a test case, he remakes the notorious Dublin bus map. (Filmed at TEDxDublin)
