The first whole genome analysis of an octopus reveals unique features that likely played a role in the evolution of traits such as large complex nervous systems and adaptive camouflage. An international team of scientists sequenced the genome of the California two-spot octopus—the first cephalopod ever to be fully sequenced—and mapped gene expression profiles in 12 different tissues. The findings are published online Aug. 12 in Nature.(more…)
Results Could Aid Future Efforts to Monitor Health
Bacteria are invisible to the naked eye, but they reside on nearly every surface humans encounter—including the skin. Uncovering the role these microorganisms play in human health is a major focus of research in skin microbiology, but little is known about the identity or function of skin bacteria in other mammals.
In a paper published in the open access journal PLOS ONE, researchers at Woods Hole Oceanographic Institution (WHOI) and colleagues identified a core skin bacterial community that humpback whales share across populations, which could point to a way to assess the overall health of these endangered marine mammals.
