Luminous poisoning? Go on, do what I tell you.

The GlowintheDark Flashlight!

(Sachiko) Hotaru.

Harry's really slow to catch on.

Turn it on turn it off.

But the pay off is really enormous.

The reason that Vibrio fischeri is doing that comes from the biology.

You must steel yourself for a shock, Mr. Bigelow. Well go on, Doctor, what is it you're trying to tell me?

What's the trouble here?

What's the yield?

Thermosalinographs, fluorometer, carbon analyzer...

So in this example, the transmittance of number 1 would be the amount that got through over the amount that you put in.

Now bright, now dimmed, was the moonlight pale,

The yield. Come on.

We're trying to preserve nerves we can't see where they are.

Tell them to prepare a stomach wash for luminous poisoning.

Interestingly enough, that corresponds to the riot of omega matter to the omega of variance in unknown at large.

And for that reason, we cover the LED with a phosphor cap.

So dark matter will stay.

Well, the GlowintheDark Flashlight, that was mine.

This bacterium has the special property that it makes light, so it makes bioluminescence,

The one thing we need to do is we have to replace these inefficient incandescent light bulbs, florescent lights, with this new technology of LED,

So let me switch colors just to ease the monotony.

I must replace that fluorescent lamp.

A firefly?

Hotaru?

And so when the people who defined it said, well you know, what we care about is how much is transmitted versus how much went in.

And this is what I think is the magic of fluorescence.

But one of the most popular ones involves green fluorescent protein.

Hotarubi!

Hotarubi!

Hotarubi...

However, we've discovered that there's actually no straightforward mechanism to develop a molecule for one time use.

And this little piece was shown just for the spring session.

Uh, when I started farming,

And now, boom, the tumor labels itself and it gets fluorescent.

Since August 2012, harmful phosphors have been found in the instant noodle package cups from every famous brand sold in China's supermarkets.

That's a third of the U.S. population.

Why Hotarubi?

look. So, a diffuse term is fine.

It's just a faster way of saying

700 rads per shot. (Laughter)
