Crystal structure and functional characterization of an Asp49 phospholipase A2 from the bushmaster (Lachesis muta)

open access: yesActa Crystallographica Section F, Volume 82, Issue 5, Page 150-159, May 2026.
The crystal structure of an Asp49 phospholipase A2 from L. muta is reported, revealing a tetrameric assembly, catalytic conservation and a polarized electrostatic surface potentially linked to membrane targeting.Snake‐venom phospholipases A2 (PLA2s) are small, structurally conserved enzymes that contribute significantly to the pathophysiology of ...

COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1617-1627, May 2026.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

open access: yesArchaeometry, Volume 68, Issue S2, Page S104-S129, May 2026.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

Things at Work: How Things Contribute to Performing Work

open access: yesJournal of Management Studies, Volume 63, Issue 3, Page 1155-1191, May 2026.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.

Snake-like robot using LiDAR

open access: yes, 2020
Denne rapporten er en fortsettelse av et mekatronikk-prosjekt som ble laget for et teoretisk redningsoppdrag etter f.eks. jordskjelv. Målet med prosjektet er å gjøre roboten mindre avhengig av stabile omgivelser. For å løse dette ble det tatt i bruk ROS for å få implementert kartlegging og navigering.
