AM fungi have been associated with land plants for a long time, but itβs fair to say their lineage had an equally long evolutionary prehistory. So mysterious!

Two studies place the split between AM fungi and other fungi between ~800 million and 1 billion years ago, far earlier than the oldest fossil evidence of AM symbiosis (~400-450 Mya), and the first land plants (~475 Mya).
Every year or so, the position of AM fungi in the Fungal Tree of Life seems to shift. It happened again in 2025-2026: AM fungi were reported as sister to Mucoromycotina, then as sister to Dikarya + Entorrhizomycota. One consistent takeaway, though, is the timing...
Wow! Here's some solid evidence that arbuscular mycorrhizal fungi use small RNAs to regulate plant gene expression. Congratulations to the teams of @carogutj.bsky.social and Arne Weiberg

Hron, @dalibormiklik.bsky.social @hpaces.bsky.social et al. demonstrate that avian dot microchromosomes harbor widespread gene attrition; retained dot chromosomes genes exhibit a new form of dynamic genetic instability - sequence stuttering.

A sedge. It may look unassuming but its genome has several unusual features.
Why do the chromosomes of cyperids (sedges & rushes) split and fuse so regularly on evolutionary timescales?
Is it because they have so many centromeres?
Our new preprint, the first major paper of my PhD, addresses this question. π§΅β¬οΈ 1/12

In applying AI to material science, biology, etc, capitalism is trying to shed science.
The point is to substitute the engineering of a machine that can generate what science has hitherto done, but without having people know things. Knowledge ultimately residing in private property is the dream.
