I’m an NIH whistleblower. The scientific community cannot afford to avoid politics β€œScientists are often encouraged to avoid politics. But this advice is outdated, if it was ever correct in the first place,” writes Jenna Norton, NIH whistleblower.

A heads down approach will not save science. We need to speak up, live our values, and demand integrity.

Historic oil painting RCS 15 from the church with signs of biodeterioration on both sides. (A) Front side of the painting, (B–D) Back, (E–G) Stratigraphy of the painting under UV light. (E), the ground layer, the paint layer, and the surface of the varnish (F), and the ground layer and the paint layer (G), all with visible penetration of dark septate hyphae. Light and Scanning electron microscopy (SEM) (K–M) images show conidiogenous structures of Aspergillus on the back and massive growth on the front side of the painting.

RIP the mold? Or the library?

Xerophilic fungi like Aspergillus thrive at very low moisture and slowly consume paintings and paperβ€”maybe by switching on enzyme genes that digest cellulose, glues, and binders.

The two male Lions "Torn Ear" and "Dark Mane" look intensely at each other, sizing each other up. Lean and muscular, these males are in their prime and each weigh in at nearly 1000 stoats (220kg/485 lbs) #StoatsAsMeasurement. Their manes are also appropriately fluffy. #2026MMM

You can use your sniffer to detect this process of ~biodeterioration~ in a library or bookstore: the by-product volatile organic compounds have a particular musty smell. Don't sniff too long, though; mold growth can make health conditions like asthma much worse. #2026MMM

Our other combatant is the second most dangerous threat to libraries worldwide...MOLD! (Jaddaoui, Ghazal, and Bennett 2023) Molds are a type of structure certain fungi make and are *primo* at breaking down organic matter from plants and animals. #NotMyLeatherBoundBooks #BOOKCARNAGE #2026MMM
