For some reason, says educator Al Vernacchio, the metaphors for talking about sex in the US all come from baseball -- scoring, getting to first base, etc. The problem is, this frames sex as a competition, with a winner and a loser.

The easiest way to alienate young STEM students is to reduce scientific concepts to dry equations and bullet points on the pages of a textbook. Scientist and educator Ashwini Bhandiwad explains how cooking can teach children actionable lessons about scientific principles, allowing them to learn (and to fail) in an engaging, low stakes environment.

A skyrocketing demand for food means that agriculture has become the largest driver of climate change, biodiversity loss and environmental destruction. Jonathan Foley shows why we desperately need to begin "terraculture" -- farming for the whole planet.

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 fo...

Each year, the world loses enough food to feed half a billion people to fungi, the most destructive pathogens of plants. Mycologist and TED Fellow Mennat El Ghalid explains how a breakthrough in our understanding of the molecular signals fungi use to attack plants could disrupt this interaction -- and save our crops.
