Comparing Paleointensity Recording Efficiencies of Detrital and Biogenic Magnetite by Deposition Experiments With Synthetic Sediments

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Marine sediments contain magnetic mineral particles of detrital, biogenic and authigenic origin that record changes in the direction and intensity of the geomagnetic field over geological time. Previous studies have demonstrated that the recording efficiencies of detrital and biogenic magnetite differ.

The Study of Microbial Physiology Under Microoxic Conditions Is Critical but Neglected

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Microbial physiology is mainly studied under aerobic or anaerobic/anoxic conditions, neglecting microbial behaviours in diverse microoxic conditions. The current article revisits the definition of microoxia in light of recent developments in oxygen‐sensing technology and emphasises the need to understand microbial physiology and growth behaviours of ...

Surface expression of protein A on magnetosomes and capture of pathogenic bacteria by magnetosome/ antibody complexes

Frontiers in Microbiology, 2014
Magnetosomes are membrane-enclosed magnetite nanocrystals synthesized by magnetotactic bacteria (MTB). They display chemical purity, narrow size ranges, and species-specific crystal morphologies.

Unveiling Structural Heterogeneity and Evolutionary Adaptations of Heteromultimeric Bacterioferritin Nanocages

Advanced Science, Volume 12, Issue 20, May 29, 2025.
This study explores the structural heterogeneity and evolutionary adaptations of heteromultimeric bacterioferritins. Hetero‐Bfrs, evolved from either a homo‐Bfr or Ftn by gene duplications, differ from homo‐Bfrs substantially in the mechanisms underpinning iron oxidation and reduction despite high similarity in overall structure.

Engineered Living Energy Materials

Interdisciplinary Materials, Volume 4, Issue 3, Page 412-455, May 2025.
Engineered living energy materials (ELEMs) are nascent research frontier for enabling sustainable energy conversion and storage. These materials exhibit unique characteristics such as self‐regeneration, biodegradability, environmental response, and evolutionary adaptability. This paper overviews different energy conversion bio‐modules, summarizes their
