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

open access: yesPapers 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

open access: yesEFSA 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

open access: yesEnvironmental 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 ...

Re‐evaluation of acesulfame K (E 950) as food additive

open access: yesEFSA Journal, Volume 23, Issue 4, April 2025.
Abstract The present opinion deals with the re‐evaluation of acesulfame K (E 950) as a food additive. Acesulfame K (E 950) is the chemically manufactured compound 6‐methyl‐1,2,3‐oxathiazin‐4(3H)‐one‐2,2‐dioxide potassium salt. It is authorised for use in the European Union (EU) in accordance with Regulation (EC) No 1333/2008.

Screening and Antioxidant Activities Evaluation of Peptides From Abalone (Haliotis discus hannai Ino)

open access: yesFood Science &Nutrition, Volume 13, Issue 2, February 2025.
This study focused on Haliotis discus hannai Ino and used virtual enzymatic hydrolysis technology to establish a peptide library. By focusing on the Keap1–Nrf2 antioxidative pathway and using molecular docking technology, we screened for abalone‐derived antioxidant peptides with strong Keap1 binding ability and validated their antioxidative activities ...

Life Course Considerations in Environmental Health: Developmental Neurotoxicity of Domoic Acid at Doses Below Acute Effect Levels in Adult Humans

open access: yesBirth Defects Research, Volume 116, Issue 12, December 2024.
ABSTRACT Background Current US federal action levels for domoic acid (DA) in seafood are based on acute toxicity observed in exposed adult humans. Life course considerations have not been incorporated. The potential for developmental neurotoxicity (DNT) at permissible DA levels has previously been noted, but not methodically assessed.
