TL;DR: The initial increase of O2 in the atmosphere, its delayed build-up in the ocean, its increase to near-modern levels in the sea and air two billion years later, and its cause-and-effect relationship with life are among the most compelling stories in Earth’s history.

TL;DR: In vivo, BHB or a ketogenic diet attenuates caspase-1 activation and IL-1β secretion in mouse models of NLRP3-mediated diseases such as Muckle–Wells syndrome, familial cold autoinflammatory syndrome and urate crystal–induced peritonitis and the findings suggest that the anti-inflammatory effects of caloric restriction or ketogenic diets may be linked to BHB-mediated inhibition of theNLRP3 inflammasome.

TL;DR: In this article, it was shown that occurrences of BIF, GIF, Pherozoic ironstones, and exhalites surrounding VMS systems are linked to diverse environmental changes.

TL;DR: In this article, a suite of Proterozoic sediments from China, Australia, and North America, interpreted in the context of data from similar depositional environments from Phanerozoic time, were used to find evidence for inhibited oxidation of chromium at Earth's surface in the mid-Proteozoic (1.8 to 0.8 billion years ago).

TL;DR: Evidence for inhibited oxidation of Cr at Earth’s surface in the mid-Proterozoic is found, suggesting that atmospheric O2 levels were at most 0.1% of present atmospheric levels.
