Gain‐of‐Function Engineering of the NifEN Scaffold Into a Self‐Assembling Nitrogenase
From scaffold to enzyme: Systematic engineering of the cofactor maturation scaffold NifEN reconstructs the P→M electron relay along with cofactor coordination and proton gating at the S2B site, converting NifEN into a functional nitrogenase capable of ATP‐dependent N2 reduction both in vitro and in vivo.

A digital twin framework is presented for modular soft continuum arms built from fiber‐reinforced pneumatic actuators. Cosserat rod models describe individual actuators, while virtual assemblies are formed through serial and parallel networks, preserving actuator‐level architecture and arm deformation.

We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Improving access to new technologies: An experiment with Kenyan input sellers
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Abstract Lessons Learned Osimertinib has confirmed effectiveness in this real‐world population of patients with EGFR‐mutant advanced non‐small cell lung cancer. Thromboembolic events occur more frequently than previously reported, suggesting a thrombotic diathesis that requires further investigation. Patients with at least three metastatic sites, brain

Discovery of the Cyclic Form of MRI pH‐Sensor Z‐OMPD Enables >5% 13C Hyperpolarization by SABRE
With “c‐OMPD”, we discovered a previously unknown 5‐membered lactol structure that arises from the homoaldol condensation of the central metabolite pyruvic acid. We demonstrate that the cyclization equilibrium is of crucial importance for OMPD's function as MRI‐based pH sensor and achieve for the first time 13C polarization levels (>5%) by SABRE in the
