Synthesis of USP Grade [2,3,7‐13C3]‐Nicotinamide for Human Pharmacokinetic Studies

Journal of Labelled Compounds and Radiopharmaceuticals, Volume 69, Issue 12, October 2026.
We prepared a 17.8‐g quantity of [2,3,7‐13C3]‐nicotinamide in five synthetic steps, with a 42% overall yield, and purified it to > 99% homogeneity, meeting USP standards for oral pharmaceutical dosing. This material is intended for tracking the movement and metabolism of nicotinamide through the human body.

A recipe for recovery: diet as a decisive tool in species conservation

Oikos, Volume 2026, Issue 10, October 2026.
Animals consume foods in specific quantities and ratios to meet a multi‐dimensional nutrient target that maximizes their fitness. Attempts to reach this target in an ever‐changing nutritional landscape often influence animal foraging behavior, habitat choice, and food‐web interactions. Consequently, understanding the nutritional ecology of a species is

A Late Cretaceous‐Eocene Geomagnetic Polarity Time Scale (MM26) That Combines Marine Magnetic Anomaly Records, Radioisotopic Dates, and Astrochronology

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Geomagnetic Polarity Time Scale (GPTS) is essential to date geological events in stratigraphic sequences and to reconstruct plate motions. The first GPTSs were based on the record of magnetic anomalies created by seafloor spreading, calibrated by a few radioisotopic dates.

3D Architecture of Kodiak Butte as Evidence of Fluvial or Shoal‐Water Environments in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Functional trait modules link climatic niche geometry to projected range change in global butterflies

Functional Ecology, Volume 40, Issue 10, Page 3225-3242, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming is redistributing insects, but species‐level projections alone rarely show which functional strategies are most exposed or how traits are linked to climatic niche structure.

Integrating local habitat structure and landscape heterogeneity is essential to conserve multitaxonomic biodiversity in European primary forests

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.
Our results demonstrate that the drivers of primary forest biodiversity are largely context‐dependent; therefore, conservation strategies based on single biodiversity indicators or individual structural targets are likely to be ineffective. To mitigate the impacts of habitat loss and conserve the full spectrum of primary forest biodiversity, management
