Lunar activity from recent gas release

Article Abstract:

A study reports that patches of the lunar regolith in the Ina structure were removed recently and that the preservation state of relief, the number of superimposed small craters, and the freshness of the regolith together has indicated that features within this structure must be as young as 10 Myr. It is proposed that these features result from recent, episodic out-gassing from deep within the Moon, which might have contributed to the radiogenic gases detected during past lunar missions.

Prolonged KREEP magmatism on the Moon indicated by the youngest dated lunar igneous rock

Article Abstract:

Primordial solidification of the Moon resulted in the formation of a variety of rock types that subsequently melted and mixed to produce the compositional diversity observed in the lunar sample suite. The initial rocks to crystallize from this Moon-wide molten layer contained olivine and pyroxene and were compositionally less evolved than the plagioclase-rich rocks that followed.

Antibiotic-mediated antagonism leads to a bacterial game of rock-paper-scissors in vivo

Article Abstract:

The colicin production promotes strain diversity, in a spatially structured, non- transitive interaction, as in the classic non-transitive model rock-paper-scissors. The narrow-spectrum antibiotics produced by Escherichia coli and its close relatives, are called colicins.
