Cooperative human signals to honeyguides form local dialects

open access: yesPeople and Nature, Volume 8, Issue 3, Page 682-694, March 2026.
Abstract Human language enables the exchange of complex information and precise instructions for collaborative planning and action. It rapidly evolves through social learning, generating diverse cultural communication signals used not only with other humans, but also with domesticated animals bred or trained to respond.

Superbasic Anionic Calcium Alkyl Complexes: Templated Twofold Deprotonation of Benzene

open access: yesAngewandte Chemie, Volume 137, Issue 48, November 24, 2025.
A family of molecular anionic calcium alkyl complexes is described. Compared with their neutral analogues, these anionic systems show markedly higher basicity, exemplified by the templated twofold deprotonation of benzene to give an inverse‐crown areneide complex.

Effects of Dissolution Regimes on Flow Channelization and Solute Transport in 3D Fracture Networks: Insights From Graph‐Based Reactive Transport Modeling

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract We investigate how mineral dissolution reshapes flow pathways and solute transport in three‐dimensional discrete fracture networks using a computationally efficient graph‐based reactive transport model. The DFNs are inspired by field‐site observations of fractured carbonate and represent realistic connectivity and structural heterogeneity ...

A Growth‐Coupled Evolutionary Strategy Enhances Heme Biosynthesis in Saccharomyces cerevisiae

open access: yesBiotechnology Journal, Volume 21, Issue 1, January 2026.
Graphical Abstract and Lay Summary Introducing a plasmid with a heme‐responsive promoter connected to a growth‐promoting gene into Saccharomyces cerevisiae created a positive feedback loop between intracellular heme levels and cell growth. After 100 h of adaptive evolution, the plasmid was removed, resulting in a mutant strain that exhibited an ...
