This depiction of viral threats confronting both bacteria and people, and the protein and cellular defenses arrayed against them, illustrates how human immunity traces part of its antiviral arsenal to ancient microbial predecessors. This shared defensive heritage is already suggesting novel tools for molecular biology and new approaches to medicine.

“Time is our teacher.”

At Yale College Class Day, celebrated author Min Jin Lee ’90 urged the Class of 2026 to think deeply about time, uncertainty, and the choices ahead.

Speaking to a jubilant crowd on Old Campus, Lee drew on the wisdom of the ancient Greeks as graduates celebrated one of Yale College’s most beloved traditions, a ceremony that dates back to the 19th century.

CryoEM revealed a striking structure. VIPR wraps around DNA as a protein filament, holding the guide RNA and both DNA strands together in a triplex core.

[rcsb pdb 💉🧬💻🔬💊🌱🧠🦠 @buildmodels]

A strand of RNA has been discovered to perform two key reactions required for self-replication. The molecule offers a clue towards understanding the origin of life, namely how non-living chemistry on prebiotic Earth started to self-replicate and evolve.

Congrats to Pujuan, Hyunbin, and Carlo (and the whole Gao lab)!!🥳🧬🎉

[News from Science @NewsfromScience]

For decades, biology textbooks have enshrined a simple rule: DNA is made by copying a template. After one enzyme unzips a DNA double helix into separate strands, another called a polymerase builds a complementary sequence, base by base, for each strand. Presto: two copies of the original DNA.

But new research into how bacteria defend themselves from viruses now shows this synthesis rule isn’t absolute.

Now, a team describes a bacterial enzyme that synthesizes DNA without a nucleic acid template, using its own structure as a guide.
