The fantastically weird world of photosynthetic sea slugs | Michael Middlebrooks
TED Talks Science and Medicine
by TED, Michael Middlebrooks
1y ago
Meet the fantastically colorful and astonishingly adaptable sea slugs that found a way to photosynthesize (or create energy from sunlight) like plants. Diving deep into these often overlooked creatures, invertebrate zoologist Michael Middlebrooks introduces the solar-powered slugs that lost their shells -- but gained the ability to directly harness the power of the sun ..read more

Where does your sense of self come from? A scientific look | Anil Ananthaswamy
TED Talks Science and Medicine
by TED, Anil Ananthaswamy
1y ago
Our memories and bodies give us clues about who we are, but what happens when this guidance shifts? In this mind-bending talk, science writer Anil Ananthaswamy shares how the experiences of "altered selves" -- resulting from schizophrenia, Alzheimer's, foreign limb syndrome or other conditions -- shed light on the constructed nature of identity. He breaks down where our sense of self comes from and invites us to challenge our assumptions about who we are, with the aim of building a better you and a better world ..read more

Can we feed ourselves without devouring the planet? | George Monbiot
TED Talks Science and Medicine
by TED, George Monbiot
1y ago
Farming is the worst thing humanity has ever done to the planet, says journalist George Monbiot. What's more: the global food system could be heading toward collapse. Detailing the technological solutions we need to radically reshape food production -- from lab-grown, protein-rich foods to crops that don't require plowing -- Monbiot shares a future-focused vision of how humanity could feed itself without destroying the planet ..read more

How to harness the ancient partnership between forests and fungi | Colin Averill
TED Talks Science and Medicine
by TED, Colin Averill
1y ago
If we want to better understand the environment and combat climate change, we need to look deep underground, where diverse microscopic fungal networks mingle with tree roots to form symbiotic partnerships, says microbiologist Colin Averill. As we learn more about which of these fungi are most beneficial to forest health, we can reintroduce them into the soil -- potentially enhancing the growth and resilience of carbon-trapping trees and plants. Hear more about the emerging science aiming to supercharge forest ecosystems, one handful of soil at a time ..read more

How green hydrogen could end the fossil fuel era | Vaitea Cowan
TED Talks Science and Medicine
by TED, Vaitea Cowan
1y ago
As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team's work mass producing electrolyzers -- devices that separate water into its molecular components: hydrogen and oxygen -- and shows how they could help make green, carbon-free fuel affordable and accessible for everyone. "This is how we end the fossil fuel era," Cowan says ..read more

How we're reverse engineering the human brain in the lab | Sergiu P. Pasca
TED Talks Science and Medicine
by TED, Sergiu P. Pasca
1y ago
Neuroscientist Sergiu P. Pasca has made it his life's work to understand how the human brain builds itself -- and what makes it susceptible to disease. In a mind-blowing talk laden with breakthrough science, he shows how his team figured out how to grow "organoids" and what they call brain "assembloids" -- self-organizing clumps of neural tissue derived from stem cells that have shown the ability to form circuits -- and explains how these miniature parts of the nervous system are bringing us closer to demystifying the brain ..read more
