Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

New conjugates of amiridine and salicylimine/amine with an N‐acylalkylene spacer were synthesized. N‐acylation of amiridine conjugates leads to a decrease in their protonation, resulting in a substantial reduction in anticholinesterase activity and relative inability to block Aβ42 self‐aggregation compared to previously studied analogs with an N ...

How to Predict the Phase Shift of “Warm Arctic–Cold Eurasia” Pattern Between Early and Late Winter?
Abstract The “Warm Arctic−Cold Eurasia” (WACE) pattern frequently undergoes distinct phase reversals between early and late winter, posing significant challenges for climate prediction. Current state‐of‐the‐art real‐time prediction models exhibit limited skill in forecasting WACE reversals, and the main reason is poor representation of key atmospheric ...
