Well-preserved fossils reveal an extreme morphological specialization of fly larvae, and broaden our understanding of the diversity of ectoparasitism in Mesozoic insects.

A missing link between the AP complexes and COPI sheds light on the evolution of vesicle coat proteins and trafficking pathways in the earliest eukaryotes.

Co-evolving residue pairs in the different components of a protein complex almost always make contact across the protein–protein interface, thus providing powerful restraints for the modeling of protein complexes.

Pair-rule genes in the wasp Nasonia function as in Drosophila in patterning anterior segments, and similar to ancestral insects in patterning posterior segments, illustrating a mixed-mode transition state between short and long germ embryogenesis.
Experiments on E. coli show that multiple mechanisms contribute to extreme resistance to ionizing radiation in bacteria, with mutations to three genes for DNA repair having a prominent role in one evolved population.
