Scientists from the Max Planck Institute for Brain Research and the Okinawa Institute of Science and Technology studied camouflage in the common cuttlefish (Sepia officinalis) — a master of camouflage — as behavior moves toward matching the background in skin pattern space. Their observations suggest that the cuttlefish’s camouflage system is highly flexible and adaptable, … Read more

Understanding how complex eukaryotic cells arose from prokaryotic ancestors represents a major challenge in biology. The main point of contention in refining scenarios of eukaryogenesis revolves around the exact relationship between Archaea and eukaryotes. In the new research, scientists from the University of Texas at Austin and elsewhere have generated 63 new Asgard archaea genomes … Read more
