A form of algae with a property of luminescence.

Where's the switch?

I ran into a lamppost.

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

So we're coming up with these beautiful fluorescent dyes, and you saw one on the first page in this podcast.

So that's the beauty of having a tumor that's labeled with fluorescent molecules.

(this was back before ideas came in compact fluorescent)

Four Parties proposed projects targeting improved efficiency of lighting.

So that's essentially the computational equivalent of two light switches.

Trees, cracks in the sidewalk, lampposts. I'm going mad.

Ship's beeper will as usual sound 10 times after lights dim.

This is powered by wind. All of the lights are daylight bulbs.

And when we made a solution of this, tagged with the fluorescence and injected in the body of a mouse, their nerves literally glowed.

I think the end of the story of the whaleship Essex offers an illuminating, if tragic, example.

And back in 1880, it would have been 15 minutes to earn that amount of light on the average wage.

And think of things in your life that are binary, one of them is light switches.

And when we made a solution of this, tagged with the fluorescence and injected in the body of a mouse, their nerves literally glowed.

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

But this is like looking for one s lost keys under the lamppost because the light is better there.

They ushered me down a narrow set of stairs that led to this dirty, dimly fluorescent lit basement.

During 1996 1998, China implemented the Green Lighting Program and 267 million high efficiency products were marketed.

Back in 1950, you would have had to work for eight seconds on the average wage to acquire that much light.

I count the steps and the lampposts and all those things that visually impaired people have a tendency to have a lot of meetings with.

I've come across some other just, kind of, curious relationships of bollards on the street that have different interpretations, but these things amuse me.

Can we engage people more in the lighting projects that we create, so they really want to connect with it, like here?

In the 1970s, emissions of chlorofluorocarbons (CFCs) in industrial applications were linked to destruction of the ozone layer.

I used to be like that, shaking hands with lamp posts because I didn't wanna be called four eyes.

While other materials can be used, most models use a fluorescence based substrate because it is very easy to detect, even at the single molecule limit.

Light from the electric streetlamps lay pale here and there on the ceiling and on the higher parts of the furniture, but underneath around Gregor it was dark.

How long do you actually have to work to earn an hour of reading light if you're on the average wage in Britain today?

What needs to happen now is further development of our technology along with development of the instrumentation that allows us to see this sort of fluorescence in the operating room.

I won't go into this very much, but our technology, besides being able to tag tumor and metastatic lymph nodes with fluorescence, we can also use the same smart three part molecule to tag gadolinium onto the system so you can do this noninvasively.

I've come across some other just, kind of, curious relationships of bollards on the street that have different interpretations, but these things amuse me.

For instance, when electricity was privatized, the Minister of Commerce, Science and Technology exempted the Light and Power Company from the application of the FCA.

Consequently, the combination of labels which can be used depends on the wavelength of the lamp(s) or laser(s) used to excite the fluorochromes and on the detectors available.

This is a face scanning sphere, with 156 white LEDs all around that allow us to photograph her in a series of very controlled illumination conditions.

The green fluorescent protein (GFP) is a protein composed of 238 amino acid residues (26.9 kDa) that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range.

110. The Montreal Protocol called for the phase out of ozone depleting substances (ODS) such as CFCs and halons by the year 2000, with developing countries allowed a ten year grace period.

Nevertheless, the increased trend toward the use of hydrocarbons, ammonia, carbon dioxide and low global warming potential fluorocarbons had been noted in various applications, as had been the increasing trend to use secondary loop systems to reduce refrigerant charge and emissions.

The active line would then be run through a main isolating switch in the fuse box and then split into one or more circuits to feed lighting and appliances inside the house.

(g) Fluorescence assessment of the effect of radiation on the fluorescent properties of yeast cells in space and study of the possibility of using yeast cells as biological sensors to detect DNA deterioration caused by radiation.

Meanwhile, in the short term, low energy lighting and efficient industrial motors may sound obvious, but we are nowhere near using them as extensively as we could.

But the result is that the MDGs may divert attention from the mechanisms that produce underdevelopment rather like the drunken man searching for his keys under the lone streetlamp because the light is better there.

Infosys is redesigning every aspect of how it provides lighting, cooling, water, and transportation to their more than 100,000 employees, and aiming to reduce costs ten fold in the process.

Experimental observation In experimental biophysics, the activity of molecular motors is observed with many different experimental approaches, among them Fluorescent methods fluorescence resonance energy transfer (FRET), fluorescence correlation spectroscopy (FCS), total internal reflection fluorescence (TIRF).
