    1. The Third-Generation normalized the process of dialogue. Bar-On and his team developed a paradigm for how to work through the Holocaust through knowledge, understanding, emotions, attitude, and behavior. What they discovered is that for the Third-Generation, the Holocaust either has no relevance, which they call “under generalization” or “over generalization,” where everything is seen through the prism of the Holocaust. A more normalized reaction to a Shoah family background is the “partial relevance,” an “in-between” and more balanced perspective.
    2. The Third-Generation in America (or “3Gs,” as they are known) have only recently started to become a visible group, but not with the same intensity as the Second-Generation. Age-wise, they span the gamut from newborns to forty-year-olds. Among them, those in their twenties and thirties are grappling with identity formation, with establishing intimate relations, and with having children.
    3. From the psychological research the only significant finding is that grandchildren of survivors as a group, are higher achievers than their peers. In 2002 Ellisa Ganz found that Third-Generation individuals are twice as likely to choose an occupation in the helping professions. Ganz also found, however, that those 3Gs who are in therapy are in treatment for longer periods than a comparative group.
    4. Yoslow observed that the Third-Generation has a deep affection for humanity, which is a transformation of the post-Holocaust trauma. This process is the ability to transform the emotional effects of the Holocaust by letting go, and thus increases the quest for meaning in ones life and concern for social issues.
    5. Today, Third-Generation individuals whose professional lives have been shaped by their grandparent’s ordeals are found in the creative arts, in helping professions, human rights work and in Jewish studies and communal work. The Third-Generation members are no different from those in the Second-Generation, who gravitated towards the creative arts in order to remember the barbarity committed against the Jews living in German-occupied countries and , the Jewish life that was destroyed, and to raise consciousness about present-day racism, human-rights violations, and genocides.

    1. Despite the fact that some environmentally induced changes are heritable, these effects are not stable [30Becker C. Weigel D. Epigenetic variation: origin and transgenerational inheritance.Curr. Opin. Plant Biol. 2012; 15: 562-567Crossref PubMed Scopus (62) Google Scholar]. Specifically, it has been shown that in large populations of Arabidopsis most ‘epi-mutations’ are labile — after only a few generations, these base-pair methylations revert to their original state. Hence, epigenetic modifications in plants are of very limited significance for evolutionary processes. Accordingly, neo-Lamarckian (including Lysenkoist) concepts have been experimentally refuted by these trans-generational epigenetic analyses [30Becker C. Weigel D. Epigenetic variation: origin and transgenerational inheritance.Curr. Opin. Plant Biol. 2012; 15: 562-567Crossref PubMed Scopus (62) Google Scholar].

      Just one citation and that to an opinion article? Interesting...

    1. while those that had been moved to 25 degrees had largely lost the methylation tags. Importantly, they still maintained this reduced histone methylation when moved back to the cooler temperature, suggesting that it is playing an important role in locking the memory into the transgenes.

      Could it be that the genetic background (or importantly surrounding environment or cross talk among cells) in the first generation that were exposed to 25 C temp might have changed, and conditioned subsequent generations?

      After 14 generations, secondary changes in the propoagated genetic makeup (including cross talk) could have reverted phenotype and reset histone marks to repress gene expression.

      See if how often c.elegans mutate or show CN changes, i.e., background vs stress induced by temp changes?

    2. Worms are very short-lived, so perhaps they are transmitting memories of past conditions to help their descendants predict what their environment might be like in the future,

      ? as long as cost, e.g., energy consumption for propagating such beneficial features is not higher than needed for one's survival.
