Possible link between Earth’s rotation rate and oxygenation

چکیده

Abstract The biotic and abiotic controls on major shifts in atmospheric oxygen the persistence of low-oxygen periods over a majority Earth’s history remain under debate. Explanations stepwise pattern oxygenation have mostly neglected effect changing diel illumination dynamics linked to daylength, which has increased through geological time due rotational deceleration caused by tidal friction. Here we used microsensor measurements dynamic modelling interfacial solute fluxes cyanobacterial mats investigate daylength Precambrian benthic ecosystems. Simulated increases across historical range boosted export, even when gross photosynthetic production remained constant. This fundamental relationship between net productivity emerges from interaction diffusive mass transfer dynamics, is amplified metabolic regulation microbial behaviour. We found that resultant daylength-driven surplus organic carbon burial could shaped increase occurred during Great Neoproterozoic Oxidation Events. Our suggested mechanism, links coinciding via enhanced productivity, reveals possible contribution planetary mechanics evolution biology geochemistry.

A Possible Link Between Pyriproxyfen and Microcephaly

The Zika virus has been the primary suspect in the large increase in incidence of microcephaly in 2015-6 in Brazil. While evidence for Zika being the cause of some of the cases is strong, its role as the primary cause of the large number of cases in Brazil has not been confirmed. Recently, the disparity between the incidences in different geographic locations has led to questions about the viru...

a possible link between mineralogy of loess deposits and high incidence rate of esophageal cancer in golestan province of iran

loess and loess-like deposits cover large areas of golestan province of iran, a well-known region in the world for its high incidence rate of esophageal cancer (ec). despite numerous published works on the possible contributing factors for the observed high incidence rate, very little attention has been given so far to a possible link between the mineralogy of loess deposits in the region and e...

The link between mental rotation ability and basic numerical representations

Mental rotation and number representation have both been studied widely, but although mental rotation has been linked to higher-level mathematical skills, to date it has not been shown whether mental rotation ability is linked to the most basic mental representation and processing of numbers. To investigate the possible connection between mental rotation abilities and numerical representation, ...

A possible link between insulin glargine and malignancy: the facts

official mouthpiece of the European Association for the Study of Diabetes (EASD), sounded the alarm in a press release regarding a possible association between the use of insulin glargine and an increased risk for the development of certain malignancies compared to human insulin and other insulin analogs. 1 The evidence for such an increased risk is based on a single study recently conducted in...
