Researchers discover unique way snakes replace their teeth kingscollegelon NatureComms

were taken with a NanoZoomer 2.0HT digital slide scanner at the Faculty of Health and Medical Sciences of the University of Adelaide and visualized in the free software NDP view v.2 . was scanned using a Skyscan 1176 μCT scanner at the Department of Earth Sciences of the University of Alberta . The main acquisition settings were set to 885 ms for exposure, 100 kV for voltage, 100 μA for current, and 7.84 μm for resolution .

sp. , were used to illustrate different patterns of tooth replacement and verify the presence of internal tooth resorption. Both of these specimens had been scanned at Adelaide Microscopy using a Skyscan 1076 μCT scanner. The settings used in the scan ofwere: 550 ms for exposure, 70 kV for voltage, 200 µA for current, and 18.00 µm for resolution . The acquisition settings used forwere: 1770 ms for exposure, 85 kV for voltage, 118 µA for current, and 17.00 µm for resolution .

We have included movies of the reconstructed μCT slices through pairs of resorbing and non-resorbing teeth of

Coupling nitrate capture with ammonia production through bifunctional redox-electrodes - Nature CommunicationsCoupling nitrate capture with ammonia production through bifunctional redox-electrodes - Nature CommunicationsCoupling nitrate capture with conversion to ammonium is attractive because it combines pollutant remediation and chemical production. Here, the authors design a bifunctional redox-electrode to achieve the reactive separation of nitrate to ammonium in a single electrochemical cell.
