Evolution of transgenerational immunity in invertebrates [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2016 Over a decade ago, the discovery of transgenerational immunity in invertebrates shifted existing paradigms on the lack of sophistication of their immune system. Nonetheless, the prevalence of this trait and the ecological factors driving its evolution in invertebrates remain poorly understood.

H3K9me3 is required for inheritance of small RNAs that target a unique subset of newly evolved genes
eLife, 2019 In Caenorhabditis elegans, RNA interference (RNAi) responses can transmit across generations via small RNAs. RNAi inheritance is associated with Histone-3-Lysine-9 tri-methylation (H3K9me3) of the targeted genes.

Poultry Science, 2021 : The impact of transgenerational effects on growth performance and immunity has not yet been studied extensively within the poultry husbandry sector. An important factor is the impact of the hens on the physical well-being and fitness to the environment

Advanced Science, EarlyView.Metabolic adaption presents a vital survival strategy for E. multilocularis. This study identifies EmPDK as a central metabolic regulator governing glucose metabolic reprogramming. Oxidative stress activates EmHIF1α to induce EmPDK expression. Mechanistic characterization reveals this ROS/EmHIF1α/EmPDK axis drives glycolytic reprogramming to sustain ...

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Indelible Race Memories and Subliminal Epigenetics in Octavia Butler’s Kindred [PDF]
Intersections, 2018 Octavia E. Butler’s Kindred highlights complexities beyond those related to a tale of time-travel and a painful slave narrative. It allows us to reimagine definitions of “race memory” and “trauma” along the lines of genetic ancestry that is explored ...

Challenges, 2018 Intrauterine and early life has been accepted as important susceptibility windows for environmental exposure and disease later in life. Emerging evidence suggests that exposure before conception may also influence health in future generations.

Australian Journal of Social Issues, EarlyView.ABSTRACT In 2021, a desktop review was conducted of published references to First Nations peoples' approaches to conflict and its management in Australia (Project Stage One), culminating in a report published in 2024. This article focuses on Project Stage Two, a complex, innovative research undertaking building on the findings of Stage One, and being ...
