Stubble mulching and minimum tillage with barley

open access: yes, 1993
In the Colombian Tibaitatá CNI (2500 m.a.s.l., 14°C an bimodal rainfall) was carried out a soil management as an alternative for minimizing environmental constraints for barley or wheat production in a medial isomesic Dystric Haplustand, Some progress has been obtained by adoption of minimum tillage with or without straw in the arable layer, to ...

Ultrafast Multilevel Switching and Synaptic Behavior in a Planar Quantum Topological Memristor

open access: yesAdvanced Science, EarlyView.
Dry‐transferred Bi2Te3 layers enable a planar quantum topological memristor framework. In‐plane topological surface states facilitate ultrafast & low‐power operations. Coexisting analog and digital modes support current‐controlled multilevel states. PQTM exhibits 105 s retention, 103 cycles endurance, and reproducibility across 24 devices.

How to produce more biomass for direct seeding mulched based cropping system in sub-saharian Africa ? Example in North Cameroun [PDF]

open access: yes, 2010
In North Cameroon, from 2001 to 2006, more than 250 farmers tried direct seeding mulchbased cropping systems (DMC) in their fields. DMC systems were based on farmer traditional rotation i.e. cereal//cotton.

MicrobeDiscover: A Knowledge Graph–Enabled AI Framework for Identifying Microbes for Inorganic Nanomaterial Biosynthesis

open access: yesAdvanced Science, EarlyView.
Microbial synthesis of nanomaterials (NMs) is eco‐friendly, but the screening of microorganisms is limited by inefficient traditional methods (currently only involving∽400 microorganisms/90 NMs). We propose AI framework MicrobeDiscover, integrating a knowledge graph of microbe‐NM interactions.

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair

open access: yesAdvanced Science, EarlyView.
This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

Making Sustainable Agriculture Real in CAP 2020: The Role of Conservation Agriculture [PDF]

open access: yes, 2012
Europe is about to redefine its Common Agriculture Policy (CAP) for the near future. The question is whether this redefinition is more a fine-tuning of the existing CAP or whether thorough changes can be expected. Looking back to the last revision of CAP

Understanding Glioblastoma Dynamics Using 3D Organoids and Engineered Extracellular Matrix

open access: yesAdvanced Science, EarlyView.
A modular in vitro glioblastoma multiforme (GBM) model combining patient‐derived glioma stem‐like cells (GSC) organoid with an engineered extracellular matrix (eECM) and endothelial co‐culture enhances differentiation and GBM associated gene expression.
