The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.

Objective: The COVID-19 pandemic has offered a unique opportunity to test evolutionary hypotheses on the functionality of the behavioral immune system. The aim of the present study was to ascertain if a previous infection with COVID-19 was associated with increased levels of perceived infectability and germ aversion. Based on the calibration hypothesis, we predicted that the activation of the behavioral immune system was greater in those participants who had been infected compared to those who reported no previous COVID-19 infection.

These mechanisms offer a sort of psychological and behavioral prophylaxis against infection. The aim of this study was to assess the functionality of the behavioral immune system under conditions of strong ecological validity.

The synthesis of [Ga([12]crown-4)][GaCl] was achieved in one step from commercially available starting materials. Anion exchange was utilized to replace the reactive tetrachlorogallate anion for the perfluorophenylborate anion.
