Emergency medicine for our climate fever | Kelly Wanser

TED Talks Science and Medicine ·

2019/08/28

As we recklessly warm the planet by pumping greenhouse gases into the atmosphere, some industrial emissions also produce particles that reflect sunshine back into space, putting a check on global warming that we're only starting to understand. Climate activist Kelly Wanser asks: Can we engineer ways to harness this effect and further reduce warming? Learn more about the promises and risks of "cloud brightening" -- and how it could help restore our climate to health.

We're not doing frontline exploratory science in a huge portion of the world -- the places governments deem too hostile or disputed. What might we be missing because we're not looking? In this fearless, unexpectedly funny talk, paleoanthropologist Ella Al-Shamahi takes us on an expedition to the Yemeni island of Socotra -- one of the most biodiverse places on earth -- and makes the case for scientists to explore the unstable regions that could be home to incredible discoveries.

Grief and love in the animal kingdom | Barbara J. King

TED Talks Science and Medicine ·

2019/07/08

From mourning orcas to distressed elephants, biological anthropologist Barbara J. King has witnessed grief and love across the animal kingdom. In this eye-opening talk, she explains the evidence behind her belief that many animals experience complex emotions, and suggests ways all of us can treat them more ethically -- including every time we eat. "Animals don't grieve exactly like we do, but this doesn't mean that their grief isn't real," she says. "It is real, and it's searing, and we can

These bacteria eat plastic | Morgan Vague

TED Talks Science and Medicine ·

2019/05/28

Humans produce 300 million tons of new plastic each year -- yet, despite our best efforts, less than 10 percent of it ends up being recycled. Is there a better way to deal with all this waste? Morgan Vague describes her research with microbiologist Jay Mellies on bacteria that have evolved the unexpected ability to eat plastic -- and how they could help us solve our growing pollution problem.

TED Talks Science and Medicine ·

2019/05/02

Plants are amazing machines -- for millions of years, they've taken carbon dioxide out of the air and stored it underground, keeping a crucial check on the global climate. Plant geneticist Joanne Chory is working to amplify this special ability: with her colleagues at the Salk Plant Molecular and Cellular Biology Laboratory, she's creating plants that can store more carbon, deeper underground, for hundreds of years. Learn more about how these supercharged plants could help slow climate
