Just came across #FPbase, a community-driven database for #fluorescent #proteins and #spectral properties 🌈. Very useful for selecting reporters, comparing #excitation/ #emission #spectra, planning multi-color #imaging 🔬, and avoiding spectral overlap.

I really need to go to this creek tomorrow or Sunday…

An early 20th century uranium glass plate glowing under UV illumination. It's only slightly radioactive: 180 CPM from my 1987 Soviet G-M tube, where background is under 30 CPM.
Le documentaire "La Vie en Fluo", sur @artefr est non seulement magnifique visuellement mais aussi extrêmement intéressant pour apporter un éclairage (hoho) nouveau sur un nombre très important de comportements animaux.
Sur terre, sous l’eau ou dans les cieux, nombreux sont les animaux et les plantes à avoir développé des couleurs chatoyantes, invisibles pour l’œil humain : la fluorescence. Mais à quoi leur sert cette particularité ? C’est un champ d’études passionnant, encore peu défriché par la science, qu’explore ce documentaire aux images de toute beauté.

Most cup fungi don't fluoresce a lot, but ultraviolet light reveals unusual chemistry in this unknown Helotiales from Monteverde, Costa Rica.

Abstract For the first time, FISH was used to map 5S and 45S rDNA sequences in two species of the genus Iris L. Ten major 45S rDNA sites were detected on chromosomes and interphase nuclei of Iris pumila L. and six sites in Iris pseudopumila Tineo; 12 loci 5S rDNA were found in I. pumila, while only two were in I. pseudopumila. A high level of aneuploidy (60–80%) was revealed in I. pumila plants, which is probably associated with the hybrid origin of the species. Given the obtained results, it is quite probable that I. pseudopumila may be one of the parental forms of the allotetraploid I. pumila. The obtained data are the basis for further evolutionary studies of this species. The evolutionary changes of diploid ancestral forms following the formation of allopolyploids and the importance of ribosomal DNA sequences in detecting these changes are discussed.
