We have wondered what a complex archaeal cell might look like ever since 2014. It’s been a long road (and the journey is far from over), but it’s a good time to pause for breath and look. These Asgard archaeal cells are a surprise! And that is the joy of being a cell biologist.

As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed.

piRNAs are essential for transposon silencing in the animal germline. But how do hosts trap transposon sequences in genomic loci that help establish a piRNA response? Looking at a natural transposon invasion, Baptiste Rafanel and Kirsten Senti made some remarkable observations.
