TL;DR: The salinity measured in the sediment pore water of Lake Van (Turkey) allows straightforward reconstruction of two major transgressions and a major regression that occurred during the last 250 ka, which indicates major lake-level changes in the past.

TL;DR: In this paper, an astronomicall y calibrated stratigraphy is generated for Site 882 over the last 4 m.y.y based on fine tuning of GRAPE (gamma-ray attenuation porosity evaluator) density oscillations in the orbital precession band.

TL;DR: In this paper, the nitrogen isotope (δ15N) records of bulk sediment and foraminifera test-bound (FB) nitrogen extending back to the last ice age from the oligotrophic Gulf of Mexico (GOM) were presented.

TL;DR: For instance, the long lag time has always puzzled scientists: Why did Antarctica become covered by massive ice sheets 34 million years ago, while the Arctic Ocean acquired its ice cap only about 3 million year ago? And why didn't both poles freeze at the same time? The answer to the paradox lies in the complex interplay among the continents, oceans, and atmosphere as discussed by the authors.

TL;DR: A simple, easy-to-use spreadsheet model is presented to estimate the infection risk for different indoor environments, constrained by published data on human aerosol emissions, SARS-CoV-2 viral loads, infective dose and other parameters, and suggests that aerosols from highly infective subjects can effectively transmit COVID-19 in indoor environments.
