Taxonomy and palaeoecology of the Mesozoic family Duotaxidae Mikhalevich (Foraminifera)

Papers in Palaeontology, Volume 11, Issue 5, September/October 2025.
Abstract This paper addresses the long‐standing taxonomic issue of the supra‐species classification of Mesozoic taxa with an agglutinated wall originally included in the genus Tetrataxis, the type species of which, Tetrataxis conica, ranges into the Palaeozoic and has a different wall texture.

New developments in biotechnology applied to animals: An assessment of the adequacy and sufficiency of current EFSA guidance for animal risk assessment

EFSA Journal, Volume 23, Issue 8, August 2025.
Abstract EFSA was requested by the European Commission to provide a scientific opinion on new developments in biotechnology, including new genomic techniques, as applied to animals for food, feed and other agricultural uses. A horizon‐scanning exercise identified a variety of animals obtained with new genomic techniques, with the potential to reach the

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 ...

Texture tomography with high angular resolution utilizing sparsity

Journal of Applied Crystallography, Volume 58, Issue 2, Page 484-494, April 2025.
This article reports non‐destructive 3D texture mapping of a wide range of polycrystalline materials using synchrotron X‐rays and utilizing the sparsity of the reconstructed texture.We demonstrate an approach to the reconstruction of scanning probe X‐ray diffraction tomography data with anisotropic polycrystalline samples.
