As you get older, your eyes worsen and become susceptible to a disease called age-related macular degeneration — the leading cause of blindness, with no cure in sight. 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.

Type 2 as well can cause this problem and I don’t want to go blind so sugar is off my diet. My eyesight is bad enough now.

I need a TED talk on why we aren’t supposed to sit close to the TV

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. 💕 ☮ 🌎 🌌

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.

For everyone who is thinking its just “WE ARE WORKING ON IT” you might not be awar how valuable this video is in the Medical and science department, How it’s an invitation for every reserch students to work on the same and to on day actually make it happen. 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 😔

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!)

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?
