Current Biology 2021 May 17;S0960-9822(21)00614-X. doi: https://doi.org/10.1016/j.cub.2021.04.067The North Atlantic right whale (Narwhale, NARW) is a medium-sized toothed whale that lives year-round in the Arctic waters around Greenland, Canada, and Russia. It possesses a large ‘tusk’ from a protruding canine tooth. NARW born in recent years have experienced stunted growth, and...

To read the full abstract: Development 2017;144:3879-3893Regenerative medicine techniques are being widely investigated for organs without regenerative capacity, such as lung. Whether pluripotent stem cell derived thyroid organoids will be used in the future as a regenerative medicine approach to treat hypothyroidism is unclear. In the context of an easily available, very cheap and non-in...

Brief Summary:Heterozygous, de novo variants in KIF5B are identified in 4 individuals with osteogenesis imperfecta. Studies of these KIF5B variants in C. elegans and cell models reveal the disease-causing mechanism. KIF5B seems important for intracellular trafficking and mTOR signaling to maintain skeletal homeostasis.Several years after the description of the last new osteogenesis imperfecta (OI)-related gene, the authors repo...
