At excitation by laser 405 nm of confocal microscope the surface of fruit containing secretory cells has
fluoresced in yellow (Figures 2(a) and 2(b)).
Juveniles represented the smallest sample (one of three specimens of this age category exhibited fluorescence), and slightly more than half of the subadult specimens
fluoresced. Adults, comprising nearly two-thirds of the total sample, exhibited a significantly greater frequency of fluorescence than the pooled number of individuals representing younger age categories.
For example a + + indicates that a colony
fluoresced with a blue halo and was identified as E.
In the first DNA form, when the dye molecules were far apart, they
fluoresced green.
"All the areas that
fluoresced were display feathers that were waggled or fluffed up or showed off in courtship," she says.
The tumors that received the ultrasound
fluoresced twice as brightly as the tumors that weren't exposed to ultrasound, Kruskal reports.
Enough francium was trapped that a video camera could capture the light given off by the atoms as they
fluoresced (see image).
