  1. K-U ratio (Volcanology 🌋)

    The K/U Ratio is the ratio of a slightly volatile element, potassium, to a highly refractory element, uranium. It is a useful way to measure the presence of volatile elements on planetary surfaces. The K/U ratio helps explain the evolution of the planetary system and the origin of Earth's Moon.

  2. Refractory (planetary science) (Volcanology 🌋)

    In planetary science, any material that has a relatively high equilibrium condensation temperature is called refractory. The opposite of refractory is volatile. The refractory group includes elements and compounds like metals and silicates which make up the bulk of the mass of the terrestrial planets and ast...

    So pleased that this is out in published form
    @PLOSBiology

    The #evolutionary #origins of eukaryotic innate #immune systems have firmly crossed prokaryotic divide. Their study is fascinating, provides really interesting insights & avenues of future discovery

    Ed Culbertson & Tera Levin reveal origins of 3 families of #antiviral proteins: CD-NTases (incl #cGAS), #STINGs & #Viperins; each connecting #animal & #bacterial immunity
