Transgenerational Epigenetic Inheritance: Twists and turns in the story of learned avoidance

Evidence that learned avoidance of a pathogenic bacterium can be transmitted to future generations in C. elegans is growing.

➤ 科學辯論中的表觀遺傳遺傳:線蟲的學習經驗能否跨越世代?
https://elifesciences.org/articles/109427
研究探討線蟲(C. elegans)透過表觀遺傳機制,將從對病原菌學習到的迴避經驗傳承給後代的能力。過去的研究發現,線蟲能將迴避特定病原菌 P. aeruginosa 的經驗傳遞到至少四代。然而,近期有研究對此提出質疑,認為此現象僅限於第一代。最新發表於 eLife 的研究,則成功重現了學習性迴避可延續至第二代的結果,並指出實驗條件的差異,特別是是否使用碘化鈉(sodium azide)來固定線蟲,可能是導致先前研究結果不一致的關鍵。研究同時提及 P11 小分子 RNA 在此遺傳過程中可能扮演的角色。

Position Paper

Scientific opposition to Japan’s planned release of over 1.3 million tons of radioactively contaminated water from the #FukushimaDaiIchi #NuclearPowerPlant
disaster into the #PacificOcean.

December 2022

“The National Association of Marine Laboratories (#NAML), an organization of more than
100 member laboratories, opposes Japan’s plans to begin releasing over 1.3 million tons of radioactively contaminated water from the Fukushima-Daiichi Nuclear Power Plant into the Pacific Ocean commencing in 2023. This opposition is based on the fact that there is a lack of adequate and accurate scientific data supporting Japan’s assertion of safety.

"Furthermore, there is an abundance of data demonstrating serious concerns about releasing radioactively contaminated water.

“The Pacific Ocean is the largest continuous body of water on our planet, containing the greatest biomass of organisms of ecological, economic, and cultural value, including 70 percent of the world’s #fisheries. The health of all the world’s #OceanEcosystems is in documented decline due
to a variety of stressors, including climate change, over-exploitation of resources, and pollution.

"The proposed release of this #contaminated water is a #transboundary and #transgenerational issue of concern for the health of marine ecosystems and those whose lives and livelihoods depend on them. We are concerned about the absence of critical data on the radionuclide content of each tank, the Advanced Liquid Processing System, which is used to remove radionuclides, and the assumption that upon the release of the contaminated wastewater,
‘dilution is the solution to pollution.’

“The underlying rationale of #dilution ignores the reality of biological processes of #OrganicBinding,
#bioaccumulation, and #bioconcentration, as well as accumulation in local seafloor sediments. Many of the radionuclides contained in the accumulated waste cooling water have half-lives ranging from decades to centuries, and their deleterious effects range from #DNADamage and
#cellular stress to elevated #cancer risks in people who eat affected marine organisms, such as clams, oysters, crabs, lobster, shrimp, and fish.

"Additionally, the effectiveness of the Advanced Liquid Processing System in almost completely removing the over 60 different #radionuclides present in the affected wastewater—some of which have an affinity to target specific tissues, glands, organs, and metabolic pathways in #LivingOrganisms, including people—remains a
serious concern due to the absence of critical data.

"The supporting data provided by the Tokyo Electric Power Company and the #JapaneseGovernment are insufficient and, in some cases, incorrect, with flaws in sampling protocols, statistical design, sample analyses, and assumptions, which in turn lead to flaws in the
conclusion of safety and prevent a more thorough evaluation of better alternative approaches to disposal. A full range of approaches to addressing the problem of safely containing, storing, and disposing of the radioactive waste have not been adequately explored, and alternatives to ocean dumping should be examined in greater detail and with extensive scientific rigor.

“NAML calls on the Government of #Japan and International Atomic Energy Agency (#IAEA) scientists to more fully and adequately consider the options recommended by the #PacificIslandsForum’s Expert Panel. We believe public policy decisions, regulations, and actions must keep pace with and make use of relevant advancements in our scientific understanding of the #environment and human health. In this case, we believe policy makers have not fully availed themselves of the available science and should do so before making any final decisions on releasing this contaminated water into the Pacific. NAML members are unified in our concern about use of the oceans as a dumping ground for radioactively contaminated water and other #pollutants because such actions can negatively affect the long-term health and sustainability of
our planet.

“We urge the Government of Japan to stop pursuing their planned and precedent-setting release of the radioactively contaminated water into the Pacific Ocean and to work with the broader scientific community to pursue other approaches [like #ClosedLoop systems or binding radionuclides in concerete] that protect #OceanLife; human health; and
those communities who depend on ecologically, economically, and culturally valuable marine
resources. “

IMHO, the #Karen archetype is the wife of the plantation owner.

A walk thru #American #history will get you gum and shit on your shoes.

This is an opportunity for the memory of the Jefferson-Hemings affair to scrape the shit off.

Karens have to decide.

This is older than law enforcement.

This is #transgenerational #culture.

If Karens can accept Vance’s kids. Then they can go the extra step, and accept Kamala.

I get that emotional and psychological boundaries are critical and necessary.

Also, the world exists, society is made of people, and they use words.

Those words will cross path with your visual field.

Emotional regulation / emotional intelligence is a form of transgenerational wealth.

If you do not build it up, you cannot pay it forward.

Who will do the emotional labor, if you cannot?
