Imaging mass spectrometry of isotopically-resolved intact proteins on a trapped ion-mobility quadrupole time-of-flight mass spectrometer

, 2023
In this work, we demonstrate rapid, high spatial, and high spectral resolution imaging of intact proteins by matrix-assisted laser desorption/ionization (MALDI) imaging mass spectrometry (IMS) on a hybrid quadrupole-reflectron time-of-flight (qTOF) mass ...

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated
