Can we feed ourselves without devouring the planet? | George Monbiot
TED Talks Science and Medicine
by TED, George Monbiot
2d 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
2w 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

A virus-resistant organism -- and what it could mean for the future | Jason W. Chin
TED Talks Science and Medicine
by TED, Jason W. Chin
2M ago
What if we could use the power of DNA to create a sustainable, circular economy? In a talk about breakthrough science, synthetic biologist Jason W. Chin describes his team's work rewriting the genetic blueprint of cells to create a virus-resistant organism -- the largest synthetic genome ever made and a first step towards reimagining what life can become. Learn more about how this advancement could lay the groundwork for the sustainable factories of the future, capable of producing plastics, antibiotics and more ..read more

How green hydrogen could end the fossil fuel era | Vaitea Cowan
TED Talks Science and Medicine
by TED, Vaitea Cowan
3M 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

A giant Jurassic sea dragon, unearthed | Dean R. Lomax
TED Talks Science and Medicine
by TED, Dean R. Lomax
4M ago
Among the dinosaurs, giant sea dragons roamed the ancient ocean. Millions of years later, paleontologist Dean R. Lomax and his team freed the remains of one of these colossal creatures from the Earth. Settle in to learn about the once-in-a-lifetime discovery of the 10-meter-long Rutland ichthyosaur: the largest and most complete ichthyosaur ever unearthed in Britain and one of the greatest finds in the country's paleontological history ..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
5M 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

The future of fashion -- made from mushrooms | Dan Widmaier
TED Talks Science and Medicine
by TED, Dan Widmaier
6M ago
Your closet is likely full of all kinds of materials -- leather, cotton, nylon and polyester, to name a few -- that contribute to fashion's sustainability crisis. Biomaterials investigator Dan Widmaier explains how we could look to nature for sustainable replacements for these much-used materials and introduces a leather alternative made from mushrooms that looks great and doesn't harm the environment. "We can make fashion sustainable, and we're going to do it with science," Widmaier says ..read more

The search for the invisible matter that shapes the universe | Chanda Prescod-Weinstein
TED Talks Science and Medicine
by TED, Chanda Prescod-Weinstein
6M ago
The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can't actually see -- like dark energy and dark matter -- and therefore don't fully understand. Theoretical physicist Chanda Prescod-Weinstein takes us inside the search for this cosmos-shaping invisible matter and explains how, with the help of a new generation of telescopes, we could be closer to demystifying it than ever before. "The universe is more queer and fantastical than it looks to the naked eye," she says. (If you want to hear more from Prescod-Weinstein, check out her episode ..read more
