And the cool thing about fluorescence is that it's not only bright, it actually can shine through tissue.

A lush, fresh lipped blond, skin glowing gold, sprawls there, resplendent.

Her diamond is sparkling under the light.

It's got light organs on its belly that are flashing, fin lights.

The light that the fluorescence emits can go through tissue.

A light bulb gives light.

We make things glow.

And by night, artificial light in each one emanates and comes out to the outside.

(c) Photo neutron interrogation photo induced neutron emission occurs when the energy of an incoming photon (X ray or gamma ray) is above a certain threshold and atoms of low atomic weight undergo photonuclear reactions that emit neutrons.

And there are brittle stars that produce bands of light that dance along their arms.

This is a Christmas tree of a fish everything on this fish lights up, it's not just that lure.

With the sub's lights switched off, it is possible to see their bioluminescence the light produced when they collide with the mesh.

This is going to be a glowing source first, which is like bioluminescent bacteria.

And it would be self illuminated, because now the Sun's gone, we have no other source of light so let's make our little Earth self illuminated.

In the deep, dark ocean, many sea creatures make their own light for hunting, mating and self defense. Bioluminescence expert Edith Widder was one of the first to film this glimmering world. At TED2011, she brings some of her glowing friends onstage, and shows more astonishing footage of glowing undersea life.

There are starfish that can make light.

The moon doesn't have light of its own.

What was actually interesting to us was not that the bacteria made light, but when the bacteria made light.

I CALL TO witness the sun and his early morning splendour,

By oath of the sun and its light

By the sun and his morning brightness

By the sun and his morning bright ness,

And by the sun and its brightness

By the sun and its radiance.

By the sun and its heat and brightness,

By the sun and his brightness,

By the sun and her forenoon splendour,

By the sun and its midmorning,

By the sun and its brightness

By the sun and its noon time brightness,

I swear by the sun and its brilliance,

By the sun and its rising brightness

By the Sun and his (glorious) splendour

What Comes After Lee Kuan Yew?

They flash, and sparkle, and glow with their own living light.

This bacterium has the special property that it makes light, so it makes bioluminescence, like fireflies make light.

Aggregation induced luminescence is an original concept firstly proposed by Chinese scientists and opens up a new area of luminescent materials.

And when it starts flashing, it's just going to be one of the LEDs that's flashing very fast.

This is actually a light emitter.

We can use LEDs.

These blocks represent LEDs.

When it's alone it doesn't make any light.

Now, every LED that is made these days gives blue light.

So that light was made by a bioluminescent dinoflagellate, a single celled alga.

Some 80 to 90 percent of undersea creatures make light and we know very little about how or why. Bioluminescence expert Edith Widder explores this glowing, sparkling, luminous world, sharing glorious images and insight into the unseen depths of the ocean.
