Researchers from Austria and the United States have identified a group of giant viruses — Klosneuviruses — that harbor components of many other viruses and proteins, and their analyses suggest that Klosneuviruses acquired the various components in an evolutionarily recent time frame, likely from, and as an adaptation to, their hosts. A paper describing this discovery was published in the April 7 issue of the journal Science. Transmission...

Showcase of the different types of changes identified in high-resolution images of 67P/Churyumov–Gerasimenko during more than two years of monitoring by ESA’s Rosetta spacecraft. The approximate locations of each feature are marked on the central context images. Dates of when the ‘before’ and ‘after’ images were taken are also indicated. Note that the orientation and resolution between image pairs may vary, therefore in each image set arrows point to the location of the changes, for guidance.
