Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio‐Hybrid Robots

Advanced Science, Volume 13, Issue 15, 13 March 2026.
Crustacean exoskeletons, repurposed from food waste, are engineered into sustainable bending actuators combining biotic structure with synthetic control. The augmented exoskeletons achieve rapid and robust motion with lightweight body and can be used as part of robotic manipulators, grippers and swimmers.

Lake Hańcza – a new site for signal crayfish (Pacifastacus leniusculus Dana) occurrence in Poland

Archives of Polish Fisheries, 2018
Crayfish catches were conducted using traps in Lake Hańcza, which is the deepest lake in Poland. Two crayfish populations were found to co-exist in the lake: spiny-cheek crayfish (Orconectes limosus Raf.) and signal crayfish (Pacifastacus leniusculus ...

The gut microbiome promotes the growth performance of black soldier fly larvae by detoxifying uric acid

iMetaOmics, Volume 3, Issue 1, March 2026.
This study demonstrates the detrimental effects of exogenous uric acid (UA) on the growth of black soldier fly (BSF) larvae, highlighting the role of gut microbiota in UA degradation. We isolated UA‐degrading bacterial strains associated with BSF, including Enterococcus faecalis AHAU24.

Characterisation of the Noble Crayfish Immune Response to Oomycete-Derived Immunostimulants

Fish & Shellfish Immunology
The invasive oomycete pathogen Aphanomyces astaci significantly threatens native European crayfish populations, prompting investigations towards the effects of protective immunostimulation on the immune response of the vulnerable noble crayfish (Astacus astacus).
