Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Methane Emission from Rice Fields: Necessity for Molecular Approach for Mitigation

Rice Science
Anthropogenic methane emissions are a leading cause of the increase in global average temperatures, often referred to as global warming. Flooded soils play a significant role in methane production, where the anaerobic conditions promote the production of

Methane: A Neglected Greenhouse Gas [PDF]

Methane is a greenhouse gas that gets far less public attention than carbon dioxide. This is entirely unwarranted. Being 25 times more potent than carbon dioxide in trapping heat in the atmosphere, methane accounts for about one-sixth of all ...

Divergent Responses of Bacterial Communities to Permafrost Degradation and Their Associations With Carbon Across Vertical Profiles

Advanced Science, EarlyView.
Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

Advanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

Mitigating methane emissions in rice (Oryza sativa) farming systems: a breeding and management roadmap for low-emission genotypes in Sub-Saharan Africa

Discover Agriculture
Rice cultivation is a significant source of methane emissions in the agriculture sector in Sub-Saharan Africa (SSA). In Africa, rice is grown in flooded conditions, which promote the release of methane by methanogens that use organic exudates from the ...
