Recently, the research group led by Prof. YU Ziniu from the South China Sea Institute of Oceanology (SCSIO) of the Chinese Academy of Sciences sequenced the first complete Natuilus genome and unveiled the evolutionary features underlying the pinhole eye formation and biomineralization.
This study was published in Nature Ecology & Evolution on May 10.
Nautilus is the only surviving externally shelled cephalopod since the Palaeozoic. They have preserved many ancestral features despite a long evolutionary history, such as a chambered shell and pinhole eye.
The researchers sequenced the complete genome of N. pompilius, which is the most widespread species among nautiluses. The genome was 730.58 (Mb) in size and encoded 17,170 protein-coding genes, presenting a most compact, simple and slow-evolving genome when compared to other coleoid cephalopods.
Researchers have identified an entirely new group of microbes quietly living in hot springs, geothermal systems, and hydrothermal sediments around the world
They appear to play an important role in the global carbon cycle by helping to break down decaying plants without producing the greenhouse gas methane, the researchers report.
“Climate scientists should take these new microbes into account in their models to more accurately understand how they will impact climate change,” says Brett Baker, assistant professor at the University of Texas at Austin’s Marine Science Institute and lead author of the paper in

The tree of life just got a little bigger: A team of scientists from the U.S. and China has identified an entirely new group of microbes quietly living in hot springs, geothermal systems and hydrothermal sediments around the world. The microbes appear to be playing an important role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane. Climate scientists should take these new microbes into account in their models to more accurately understand how they will impact climate change, said Brett Baker, assistant professor at The University of Texas at Austin s Marine Science Institute who led the research published April 23 in
