Bangladeshi indigenous chicken varieties - Common Deshi, Hilly and Naked Neck are notable for their egg production, meat quality, extraordinary survivability and disease resistance. However, the potential to harness their unique genetic merits are being eroded by various factors, including crossbreeding. In-depth genomic studies have not been carried out on these breeds so far.

- The study investigates how the Lapland longspur, a wild arctic-breeding bird, reacts to extreme weather events and what coping strategies it employs.
- The researchers analyze gene expression changes using RNA-seq to see how environmental stressors like a cold spring and a severe storm impact the bird's stress response, reproductive behaviors, and metabolism.
- Key findings include the significant up-regulation of the FKBP5 gene in the hypothalamus, which contributes to understanding how the bird adapts to changing climates and provides resources for future genomic studies.
Recently, the development of composite materials from agricultural and forestry waste has become an attractive area of research. The use of bio-waste is beneficial for economic and environmental reasons, adapting it to cost effectiveness and environmental sustainability. In the presented study, the possibility of using hazelnut shell (HS) and hydrotalcite (HT) mineral filler was investigated.

- - The text discusses the severe impact of highly pathogenic avian influenza (HPAI) on poultry, leading to high mortality rates, decreased egg production, and economic losses for farmers, particularly highlighted by a 2015 outbreak in the U.S. with over 99% mortality.
- - Researchers conducted an analysis of genetic data from chickens that survived the HPAI outbreak and compared it with uninfected controls to identify genomic regions that may confer resistance to the virus.
- - They found significant associations with survival on multiple chromosomes but did not pinpoint a single genetic locus responsible for resistance; the study suggests that HPAI resistance involves various genes related to the host's cellular response to the virus.
Recently, the influence of the concept of environmental sustainability has increased, which includes environmentally friendly measures related to reducing the consumption of petrochemical fuels and converting post-production feedstocks into raw materials for the synthesis of polymeric materials, the addition of which would improve the performance of the final product. In this regard, the development of bio-based polyurethane foams can be carried out by, among other things, modifying polyurethane foams with vegetable or waste fillers. This paper investigates the possibility of using walnut shells (WS) and the mineral fillers vermiculite (V) and perlite (P) as a flame retardant to increase fire safety and thermal stability at higher temperatures.
