  • New evidences confirm the economic shellfish Mya arenaria as a species complex

    The soft-shell clam is a commercially important fishery resource that occurs in boreal and temperate environments in the Northern Hemisphere. Whether the soft-shell clam is a single species of Mya arenaria Linneaus, 1758 with a circumboreal range or a cryptic species complex also comprising M. japonica Jay, 1857 distributed exclusively in the northwest Pacific has long been debated by malacologists and paleontologists based on subtle differences in shell morphology. Researchers from IOCAS (Institute of Oceanology, Chinese Academy of Sciences), National...

  • Topographic Beta Spiral and Onshore Intrusion of the Kuroshio Current

    The water and material exchange between global ocean and marginal sea is attracting immense research interest because it significantly influences the coastal hydrodynamic environment and ecosystem. Because of the steep topography associated with shelf break and strong nonlinearity of currents, the interaction between continental shore and circulation in the open ocean remains a great challenge. We first report the topographic beta spiral inferred from observations, which is generated by strong upwelling induced when strong western boundary current runs onto steep...

  • Unusual structural features of the dUTPase of white spot syndrome virus provide a unique opportunity for antiviral development

    White spot syndrome virus (WSSV) is a serious pathogen in shrimp aquaculture, causing $1 billion economic loss every year since its emergence more than 20 years ago. It is a large DNA virus and the sole member of the genus Whispovirus and the family Nimaviridae. So far, its replication mechanism is not understood and no effective treatment is available. WSSV genome encodes more than 180 proteins and most of them have unclear functions. Interestingly, a rather complete thymidylate biosynthesis pathway...

  • China Realizes Real-time Transmission of Deep-Sea Data in 3000 meters Depth

    The research vessel “Kexue” has embarked its expedition in the Western Pacific since 26th November, 2017. Chinese scientists announced recently that they had upgraded 8 sets of subsurface moorings to achieve “live transmission” of deep-sea data over the upper 1000 meters depth, and had realized real-time transmission of temperature, salinity, and three-dimensional velocity in 3000 meters depth, a new record. Last year, they set out to overcome well-known difficulties in the long-term transmission of real-time data from subsurface moorings, and...
