Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1116-1131, July 2026.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Osmium Isotope and Highly Siderophile Element Constraints on the Cretaceous/Paleogene Boundary in Western Pacific Pelagic Clay

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Cretaceous/Paleogene (K/Pg) Chicxulub impact produced globally synchronous enrichments of highly siderophile elements (HSEs) and a pronounced decline in marine osmium isotope ratios (187Os/188Os), forming a key geochemical marker of the boundary.

Leaf Size in Conifers: Global Associations With Climate and Evolutionary History

Global Change Biology, Volume 32, Issue 7, July 2026.
Global patterns in leaf size are linked to climatic trade‐offs, so we explore these relationships in a major group of plants, the conifers. Using contemporary phylogenetic methods, we show that conifers display a strong pattern of evolutionary conservatism in the association of leaf size with climate, and highlight that these relationships are driven ...

Zinc Isotopes Reveal Cross‐Border Transport of Coal Combustion Pollutants Across the Himalayas During the Summer Monsoon

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Himalayas form a major atmospheric barrier between South Asia and Tibetan Plateau, yet cross‐barrier transport of anthropogenic metals remains poorly constrained. We use moss δ66Zn along a 750–4,100 m a.s.l. south‐north transect in Motuo to trace pollution sources and transport processes. On the southern slope, trace metals (Zn, Pb, As, Ni,

Harnessing Acoustic Cavitation Energy for the Selective Degradation of Impurities in Glucose Syrup

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
The energy released during the implosion of acoustic cavitation bubbles can be harnessed and selectively transferred to a target solute, enabling its specific decomposition without degrading other solutes present in the solution. This proof of concept was demonstrated in the degradation of impurities present in trace amount in glucose syrup.
