How we can eliminate child sexual abuse material from the internet Social entrepreneur Julie Cordua works on a problem that isn't easy to talk about: the sexual abuse of children in images and videos on the internet. At Thorn, she's building technology to connect the dots between the tech industry, law enforcement and government -- so we can swiftly end the viral distribution of abuse material and rescue children faster.

The salt from industrial uses like this often ends up in freshwater rivers, making their water undrinkable and contributing to a growing global crisis. How can we better protect these precious natural resources? Physical organic chemist Tina Arrowood shares a three-step plan to keep salt out of rivers -- and create a circular salt economy that turns industrial byproducts into valuable resources. | A love story for the coral reef crisis Over the course of dozens of scuba diving trips, marine biologist Ayana Elizabeth Johnson fell in love -- with a fish. In this ode to parrotfish, she shares five reasons why these creatures are simply amazing (from their ability to poop white sand to make colorful "wardrobe changes") and shows why they need our protection from the destruction of coral reefs. | |
