Ok what is the most death metal biology term?
Cytokine storm?
Programmed death 1?
Executioner caspase?
Other?

The double splitscreen shot from 1:13-1:42 is one of the most insane shots created during the photochemical era.
You’ve got a real woman fondling Maroon and Valiant at both ends of the shot, with the woman’s body hidden by splitscreens that run along the edges of the fluted columns in the BG…

Photochemical Formation of Trifluoroacetic Acid: Mechanistic Insights into a Fluoxetine-Related Aryl-CF3 Compound
Trifluoroacetic acid (TFA) is a ubiquitous environmental contaminant; however, its sources are poorly constrained. One understudied source is from the photochemical reactions of aromatic compounds con...

Is this a camera?*

Having some INSTAX fun today 😃
Being very serious about cinematography and photography we could hardly ignore the world’s most popular photochemical product today.
While I miss my sturdy Nikon it’s a great fun to (Li)Play with.
[*yes 👍]

Zinc Redox Catalysis in the Photochemical Borylation of Fluorocarbons. New @chemrxiv.org preprint from @upwinder.bsky.social and the team. chemrxiv.org/doi/full/10....
We show how photoredox catalysis can bypass Kasha’s rule, enabling reactions from higher excited states.
This work, led by the exceptional @bjoernpfund.bsky.social, offers new insights into photochemical reactivity.

Airglow and auroras are distinct photochemical events. While solar wind triggers auroras, airglow stems from chemiluminescence as atoms release energy. This overlap reveals the ionosphere’s complex dynamics. #Astrophysics #NASA #AtmosphericScience #Airglow #Astronomy
