A few pieces of petrified wood from the same location in Oregon at Thomas Creek, with varying fluorescence under whatever kind of UV bulb I have in my lamp. Wild.

Excited state dynamics are essential for understanding fluorescence properties in molecules, impacting their application in technologies. Recent research at Shinshu University explores how molecular structure and geometry influence light emission in aggregation-induced emission molecules. The study reveals that changes in molecular shape affect emission behavior in both solution and solid states. These insights are crucial for advancing applications like organic light-emitting diodes and bioimaging, enabling innovations in material design and energy interactions. Light emission from molecules, particularly fluorescence, has fascinated scientists for over a century, revolutionizing areas like imaging, sensing, and display technologies. Recent advancements have brought attention to aggregation-induced emission (AIE) -- a unique phenomenon where molecules emit light more efficiently when in a solid or aggregated state. Studying the reaction dynamics underlying this phenomenon, is thus, important for understanding the molecular structural changes.

When exposed to UV light bodily fluids glow, this is because of flourescent chemicals laced in tap water to help make forensics easier.

Tasmania’s enigmatic Eastern quoll (Dasyurus viverrinus) is an outsized predator whose bite strength is amongst the strongest on earth. They also glow sometimes.

I believe this is the first biofluorescence documented in the species in a wild setting, or at the very least would be amongst the clearest imagery. What a surreal experience to have a small group of them hang out for hours.

Fluorescent nanomaterial could transform how we visualize fingerprints

Researchers created a fluorescent nanoparticle using a combination of materials (MCM-41, chitosan and dansylglycine) to examine latent fingerprints. These nanoparticles have special properties that make them adhere well to fingerprint residues, even old ones. The nanoparticles work on various surfaces, including metal, plastic, glass and complex objects such as polymer banknotes. They have the potential to be used directly at crime scenes without lab facilities, which is a significant advantage over some previous reagents. They produce high-quality fingerprint images, with the vast majority of those tested meeting the UK Home Office standards for a successful identification. This new method captures the finer details of a fingerprint, making it easier to identify individuals and is expected greatly to aid in forensic investigations. The research was published in a RSC Advances paper, highlighting that the new nanomaterial has proven to be a versatile and effective tool for visualizing fingerprint evidence. Small angle X-ray scattering (SAXS) techniques at Diamond provided useful data to validate these results.

Are there any frogs that glow in the dark?

Not to my knowledge, no. There are plenty of frogs that fluoresce under specific wavelengths of light, but no true phosphorescence that is implied by 'glow in the dark'.

Some more shortwave UV photos because they were easier to edit than the longwave ones (so much dust) and so I was able to finish editing them. Arranged in a rainbow because why not? The rest are here.

Gotta love how the counter in our less than a year old chem lab already has fluorescent stains lol
