Crystal structure of Schistosoma mansoni cathepsin D1 in complex with a nanobody reveals the conformation of the propeptide‐bound state

Acta Crystallographica Section D, Volume 82, Issue 2, Page 140-150, February 2026.
Structural characterization of S. mansoni cathepsin D1 in complex with a nanobody reveals the conformation of the propeptide‐bound state and identifies a schistosome‐specific epitope.Schistosoma mansoni cathepsin D1 (SmCD1) has been shown to be an essential enzyme for helminth metabolism due to its role in haemoglobin degradation: a key amino‐acid ...

Inferring bird migration from bone isotopes and histology: A fossil‐friendly methodological framework

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 531-553, February 2026.
Abstract Bird seasonal migration is a remarkable biogeographic phenomenon, yet its deep‐time origin(s) and evolutionary history remain poorly understood, with the bird fossil record largely overlooked. This study explores the predictability of bird migratory behaviour from the oxygen isotope composition of their bone apatite phosphate (δ18Op), a ...

Southern Ocean Sulfate Aerosol Sources Quantified From Sulfur Isotopes in Antarctic Ice Cores

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Southern Ocean has emerged as a key region for constraining aerosol‐climate interactions due to its relatively low anthropogenic influence. Sulfate is an important aerosol over the Southern Ocean, and models suggest dimethyl sulfide (DMS) is the largest source of sulfate during summer.

Mössbauer Spectroscopy on Antimony Borosulfates Reveals Weak Coordination Behavior

Angewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
The weakly coordinated trivalent antimony atoms show record‐breaking low chemical Mössbauer shifts, and in combination with several monovalent cations including silver, nitrosonium, thallium cations a rich crystal chemistry of closely related but different crystal structures. Sb(NH4)[B(SO4)2]4 showed a non‐linear SHG response comparable to that of KDP.
