Conserving and restoring art can be pretty tricky. Thankfully, scientists have been learning how to restore artwork in some pretty cool ways that are effective, safe, and a little weird, to be honest.

Lasers are incredible narrow beams of light we can use to do everything from cutting metal to operating on people's eyeballs. But even though we came up with the idea on our own, humans didn’t actually make the first lasers.

Swallowing pills to get medication is a quick, painless and often not entirely effective way of treating disease. A potentially better way? Lasers. In this passionate talk, TED Fellow Patience Mthunzi explains her idea to use lasers to...

In 1948, Spanish ophthalmologist Jose Ignacio Barraquer Moner was fed up with glasses. He wanted a solution for blurry vision that fixed the eye itself, without relying on external aids. The surgery he eventually devised was called...

After Hubble and Webb, what's the future of space telescopes? Two ideas in planning stages right now involve the space-age versions of umbrellas and glitter.

Quantum mechanics is weird and seems a bit...complicated. But understanding it can help us to understand the universe.

Hank tells us about some developments that are being made in the dramatic area of laser tractor beams.

Sci-fi technology is often more fiction than science, but it turns out there are actually some real-world labs that are working on developing force fields!
