...we show that panspermia is not exclusively relegated to solar-system sized scales, and the entire Milky Way could potentially be exchanging biotic components across vast distances.
Harvard astrophysicists observe that objects like comets, asteroids or even planets can be spun away from the galactic center at velocities sufficient to reach the intergalactic medium. Considering the likely distribution of numerous variables in a fashion reminding us of the Drake equation, they firmly conclude, panspermia is viable on galactic scales.

Elegant and precise genetic programs guide the forces that allow seemingly identical starting cells to develop into highly specialized entities.... This comment comes, in a special issue of Science, in the introduction to eight articles about newly observed systems essential for controlling metazoan development. These systems utilize, for example, chromatin plasticity (illustration from Yadav et al.), dynamic DNA methylation, developmental enhancers guided by chromosome topology, and "sequence-dependent stochastic switching at regulatory loci".
Chromatin plasticity
Standard darwinism, by its logic, must eventually account for the origins of these systems, but no such accounts are yet even suggested. (To our surprise, a browser search for the case-insensitive string "darwin" found no matches in any of the nine related articles.) Meanwhile, elegant and precise genetic programs controlling development would further exemplify the robust software management that genomes require in cosmic ancestry.

Cyanobacteria thrive in the deep continental subsurface without light or oxygen. They could probably do as well in similar places on other planets or moons. So say sixteen astro- and molecular biologists after finding cyanobacteria-dominated communities deep in southwestern Spain, in rock formations analogous to ones on Mars. ...their unequivocal presence in samples from this and other studies ...increases their relevance in early life and astrobiological scenarios.
