Rethinking the 2H fingerprint of carbohydrates: a novel proxy for plant metabolism and performance The intricate architecture of plant metabolic networks and the dynamic fluxes of elements through these networks are fundamental determinants of how carbon (C) is partitioned among growth, reproducti...

Our new Tansley Review reveals hydrogen isotopes in plant carbohydrates aren't just climate indicators - they're powerful tools for understanding how plants actually function and perform metabolically.

Job offer: The Research Group Dendrosciences uses tree rings to investigate and understand environmental impacts on tree growth and to reconstruct past environmental changes at scales ranging from minutes to millennia and from cells to ecosystems around the globe. From 1 November 2025, we offer a 4-year position as a PhD in Palaeoecology 100% (f/m/d) As part of the Signatures of Global Late Glacial Climate Change in Tree-Ring Records (SiGnaL) project — co-led by the Dendrosciences group at WSL and the Laboratory of Ion Beam Physics (LIP) at ETH Zurich — you will contribute to understanding the nature and drivers of abrupt climate changes that occurred during the Late Glacial period, approximately 11 - 15 kyrs BP. Your work will focus on the collection, measurement, and integration of fossil wood and tree-ring material from various global sites. Through a multi-proxy approach — combining radiocarbon dating, stable isotope ratios, and quantitative wood anatomy — you will help to date and synchronize records across regions and reconstruct regional to global climate dynamics. This work will support the project's goal of improving our understanding of the Late Glacial climate system and enhancing the global radiocarbon calibration curve. You will be part of an enthusiastic and ambitious team that includes leading researchers in dendro-chronology, palaeoclimate research, and radiocarbon dating, along with two other PhD students and technicians. The position is based at WSL within the Dendrosciences group, a globally recognised centre for tree-ring science. Collaboration with international researchers from related institutions is also expected. Among the three PhD students involved in the project, you will have a special emphasis on wood anatomy and on the climatic interpretation of the tree-ring proxies.

As women in academia, having children can feel impossible. Talking about it makes us feel less alone The struggle is “balancing their careers not just with motherhood, but with what comes before: relationships and planning for a family,” these postdocs write

"The academic structure … makes planning for a family feel like an impossible luxury."

In this #ScienceWorkingLife, two postdocs share how, as women in academia, having children can feel impossible—and how talking about it makes them feel less alone. scim.ag/3F60VMt #InternationalWomensDay
