Sharing the science of how your vision works, researcher Joshua Chu-Tan offers breakthrough insights on a lesser-known RNA that could change the treatment for this disease, preserving the gift of sight for longer and improving the quality of life for millions of people.

    • Tamberlane Arcadia

      February 12, 2022 at 4:48 pm

      TVs used to be radioactive. It’s a holdover belief from then. It’s perfectly safe to sit close to a modern tv.

    Longevity *_and_* quality are the answer. Within 200 years (2222), science and technology will beat all diseases. The only thing, however, getting in the way of us living 1000 years or more is entropy. ???? ☮ ???? ????

      Really? Do you get the last point from the conclusion? Did you know how to cure this disease? I wish he could provide more detailed resources and research data on its treatment and result !! How about you?

    Wow I’m blown away. That was amazing. I love how educational these short talks are & i love how science is always evolving, and i totally agree that quality is way more important than time. I always said I’d rather die at 60, knowing i had a quality lifestyle, than to live to 80 & suffer poor health. I’m so thankful for the micro RNA research, it’s going to be a huge game changer. Thanks for sharing TED.

It might be a great topic for PhD, and medical marketing authorities.

    This was absolutely what you would expect from a scientific talk, no beating around the bush and delivering clear speech with personification to get to a clear understanding.Just loved it

    My first eye disection was amazing ????
    The iris like a circle comb gliding on a pupil hockey puck….the inner lining of the human eye is dull, but a sheep has luminescent film (night vision)….I always thought we could alter eye disease with stem cell research, but Bush shut that down the same year ????

    • Internet Hobo

      February 13, 2022 at 11:31 am

      I had a similar experience dissecting a cow’s eye, the retina was surprisingly pretty. Shutting down stem cell research was a huge disappointment to numerous scientists, and thankfully finding another source took away a lot of stigma ???? (plus this technology sounds amazing!)

  33. Rezin 8

    Why I invested in a certain RNA shot company ???? 3 years now

    Something doesn’t make sense. You said in humans, 124 gets overwhelmed by disease and stops being produced. But in your test animals that have undergone retinal damage, the animals would still be producing normal amounts of 124 since they didn’t have any disease. How can you then take the results of your experiments on animals and expect them to translate to human eyes?

SpaceX’s S-1 Claims a TAM as Large as the Annual US GDP

The SpaceX S-1 dropped, and the $28 trillion TAM claim inside is somehow not even the wildest part. The Equity podcast team breaks down what’s in the filing, and whether any of this math connects to reality.

The SpaceX S-1 is finally here, and the story it tells goes way further than rockets. The filing runs to 36 pages of risk factors alone, and the numbers inside match the ambition: a $28 trillion total addressable market, a pay package tied to establishing a Mars colony, and a valuation target that would make it the largest IPO in American history.

On this episode of TechCrunch’s Equity podcast, Kirsten Korosec, Anthony Ha, and Sean O’Kane dig into the week’s biggest talent shakeups, acquisitions, and headlines — including what the filing actually says and whether any of this math connects to reality.
