Under UV light, scorpions glow a vivid blue-green, and it's fluorescence, not bioluminiscence. Compounds in their cuticle turn invisible UV into visible light, even in fossils.

"Before his death, James composed a message that Professor Ryan Lister and James’s team plan to encode within an intron of a fluorescent reporter gene... Each time that chromosome produces fluorescence, the plant will quite literally have read out James’s message."
Brilliant 💚

I am deeply saddened by the news that James Lloyd has passed away far too soon. He was a wonderful colleague, person, and scientist. I will always remember him fondly.

Fluorescent Glow Reveals Hidden Glaze on Chauvet Cave’s Ancient Art | Sci.News
Some of the oldest drawings known to humanity, made roughly 37,000 years ago in France’s Chauvet Cave, are covered by a thin, translucent film of calcite that cannot be seen with the naked eye.

The blue jolly ranchers are so brightly fluorescent that their red fluorescence even shows up in ordinary sunlight.

the dust covering mars is even more dangerous than I thought was possible lol
Human exploration of Mars requires a thorough characterization of surface hazards before crews arrive. Using in situ X-ray fluorescence data from the Perseverance rover, we provide direct characterization of fine (≲2.5 µm) and ultrafine (≲0.1 µm) Martian dust fractions. These respirable particles are small enough to penetrate deep into pulmonary alveoli, bypass the blood–brain barrier, and threaten vital organs. We show that this toxic, reactive dust persistently adheres to spacesuit- and habitat-analogous materials via electrostatic and mechanical sorting. These findings deliver an empirical foundation essential for defining crew safety standards, planetary protection protocols, and environmental control designs well ahead of human surface deployment. Abstract Surface dust poses a fundamental challenge to extraterrestrial human exploration, a reality demonstrated by the operational hazards encountered during Apollo lunar missions. On Mars, this challenge is compounded by regional and global dust cycles that coat sensitive hardware. While previous Mars missions have constrained the bulk geochemistry of coarser particulates (≳3 µm), the properties of the fine (≲2.5 µm) and ultrafine (≲0.1 µm) fractions remain largely uncharacterized. This knowledge gap is critical as these respirable particles, defined by their ability to bypass upper respiratory defenses, possess the mobility to penetrate deep into the alveolar regions of biological systems, presenting a systemic toxicity risk to future crews. Here, we report on direct examination of these fine and ultrafine Martian dust fractions using X-ray fluorescence through the analysis and modeling of data acquired by the Perseverance rover. We observe particulates measuring as small as 100 to 200 nm on spacesuit samples and calibration targets. Compositionally, this dust is a phosphorus-, iron-, and sulfur-enriched mafic silicate accumulating on materials analogous to the planned external layers of potential crew systems. O…

Hi #chemsky! I am looking for books on fluorescence with an emphasis in porphyrinoids, or molecular photochemistry with an emphasis in photodynamic processes, singlet oxygen. Can anyone recommend somewhat recent books related to those topics?
Thank you very much!

I figured since I was already putting up black lights, and Bulk Barn had them on sale, I should do the thing. I don't think any kids noticed the fluorescence, but maybe it made them easier to find when they fumbled the catch from the candy chute.

In Situ Ultraviolet Fluorescence Spectroscopy for the Characterization of Translucent Calcite Coatings over Prehistoric Cave Art 🏺🧪

Ultraviolet fluorescence from the Horses panel. (A) Visible and (B) UVF imaging. (C) Spectroscopic data visualization: each diagram represents a measurement point of UVF spectroscopy. The radii of the half-disks are proportional to the normalized magnitudes of the concretion and limestone components. Corresponding normalized spectra are plotted for three measurements, highlighting the relative attenuation of the second peak (red arrow).
