Scientific Opinion on the safety and efficacy of Cibenza® EP150 (a preparation of Bacillus licheniformis (ATCC 53757) and its protease (EC 3.4.21.19)) as a feed additive for chickens for fattening, chickens reared for laying and minor avian species for fattening and to point of lay and ornamental birds

EFSA Journal, 2015
Cibenza® EP150 is a feed additive containing a protease produced by fermentation of a single strain of Bacillus licheniformis. The final preparation contains the enzyme, spores of the production organism and spent medium.

Environmental complexity: A buffer against stress in the domestic chick [PDF]

, 2019
Birds kept in commercial production systems can be exposed to multiple stressors from early life and this alters the development of different morphological, immunological and behavioural indicators.

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications

Advanced Robotics Research, EarlyView.
Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Influence of rearing environment on development of perching and dustbathing behaviour in laying hens [PDF]

, 2007
Studies have shown that perching and dustbathing behaviour in birds can be affected by how and when the behaviour develops. With the increasing trend away from cages and towards keeping laying hens in larger, more complex housing systems, it is important

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

Advanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

NIBV Induces Incomplete Autophagy via AMPK‐TFEB, Causing Kidney Injury in Chicks

Advanced Science, EarlyView.
This study reveals that NIBV can inhibit the nuclear translocation of TFEB by suppressing the expression of AMPK, leading to the blockade of autophagolysosomal functions, in turn increasing NIBV replication and triggering severe kidney injury in chicks.

A Testis‐Specific Aralkylamine N‐Acetyltransferase Regulates Dimorphic Sperm Function and Male Fertility in Moths

Advanced Science, EarlyView.
We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.
