    1. For completing tasks such as reading instructions, submit-ting an assignment, and posting to the discussion board,a chronological layout was more efficient. Figures 7 and 8are an example of individual participant’s gaze plot for eachgroup while completing the second task of reading the assign-ment instructions. The visualizations show that when giventhe instruction to complete a task by week or module, thechronological layout was more compelling at guiding partici-pant’s visual attention to the weekly modules on the naviga-tion menu. Not to mention, those in the Chronological groupcommitted fewer mistakes than participants in the Functionalgroup for all instructional activities, with the exception oflocating grades.What was les

    2. Functional group completed the prescribed tasks fasterthan the participants in the Chronological group. In particu-lar, the completion time was faster in the Functional group forstudents to locate the syllabus, look up their grades, and findthe help link. With the precise name of the link to the coursesyllabus directly at the top of the main navigation area, it wasextremely easy for participants to find correctly without delay.Similarly, looking up grades and finding the help link wasstraight-forward in the functional layout.

Thecalamity of the unexpected surrender, the “bleeding borders” re-drawn in the postwar settlement at Versailles, and the overwhelm-ing chaos of the inflation in the early 1920s were collective experi-ences that made the suffering of the nation more comprehensible.During the Weimar years, the people’s community denoted the be-leaguered condition Germans shared, while expressing the politicalunity necessary for national renewal.

The state of permanent emer-gency declared by the National Socialists helps explain the tremen-dous efforts that they and their followers made to reconstruct thecollective body and the satisfaction they took in images of unityand solidarity.

    11. Germans converted to National Socialism out of fear and for thesake of appearances. Indeed, each diary refers to concentrationcamps, arrests, and other violence. Moreover, pressure to conformto Nazi expectations persisted, a fact that Karl’s father tried topoint out. Like Friedrich Kassler, Germans also converted becausethey were persuaded finally that Nazism represented a “new direc-tion,” which offered opportunities and to which citizens simply hadto adapt. In addition, there were countless people who mistrustedthe Nazis, misunderstood their racial precepts, and resented theirhostility to the churches, but nonetheless endorsed the “nationalrevolution” of January 1933 and the political reconciliation it ap-peared to achieve. In some ways, Erich Ebermayer falls into thiscategory. Finally, Germans converted because they were genuinelyattracted to the social and political vision of National Socialism andparticularly to the promise of the people’s community.

    1. Review coordinated by Life Science Editors

      Reviewed by: Dr. Helen Pickersgill, Life Science Editors

      Potential Conflicts of Interest: None

      Impact Point: Transcription factors may mediate the release of specific genes in extracellular vesicles that could be taken up by other cells and directly influence their behaviour.

      Background: Extracellular vesicles (EVs) are nanoscale, membrane-bound vesicles containing proteins, nucleic acids and lipids that are released by most cell types. Originally thought of as a cell waste disposal mechanism, they have since been rebranded as a means of intercellular communication, both short and long range, (like a cellular postal service), and can, for example, modify gene expression and function in recipient cells via the transfer of specific RNAs (DOI: 10.1038/s41580-020-0251-y). One interesting function for EVs was the recent discovery that antigen presenting cells (APCs) could donate telomeres via EVs to recipient T cells and rescue them from senescence (DOI: 10.1038/s41556-022-00991-z).

      Given EVs contain a wide variety of cargos derived from the secreting cells, which have been extensively profiled (e.g., DOI: 10.1016/j.cell.2020.07.009) they are particularly interesting as sources of biomarkers for diagnosing diseases such as cancer (e.g., DOI: 10.1038/s12276-019-0219-1). We might also be able to use them as stable delivery mechanisms for controlling cell behaviour or targeting therapeutics/diagnostics.

      We know quite a bit about how RNAs and proteins are selected for secretion by EVs (mediated by the autophagy protein LC3: e.g., DOIs: 10.1080/15548627.2020.1756557; 10.1038/s41556-019-0450-y). But little is known about DNA. DNA presents a particular challenge as it is packed up into the nucleus. This is also particularly important to understand in the context of horizontal gene transfer, i.e., passing functional genes between cells.

      Main question: How does a cell ‘select’ specific DNA cargo from the nucleus and enable it to be released by EVs?

      The advance: They discover that a transcription factor (FOXM1) plays a central role in mediating DNA release in EVs.

      Results: • FOXM1 and LC3 (autophagy protein) colocalize and interact in cultured cells (coIP endogenous and exogenous, EMSA, immunostaining and identify an FOXM1-binding domain mutant). • FOXM1, LC3 and DNA colocalise in the cytoplasm in cultured cells, which increases upon starvation-induced autophagy (immunofluorescence). • FOXM1 and LC3 are found in EVs released from cultured cells (Western blot). • 15,544 DNA identified in EVs released from cultured cells (evDNA sequencing), of which 25 overlapped with DNA loci binding FOXM1 (ChIP). • FOXM1-bound nuclear DNA is transported to the cytoplasm upon induction of autophagy and is released in EVs in cultured cells (knock-in tagged chromatin with CRISPR-cas9, IF and PCR). This is dependent on FOXM1 (knock-out in cultured cells).

      Significance: Transcription factors display strong DNA binding specificity and so are ideal candidates for directing specific genes into EVs for potential transfer to recipient cells.

      Remaining questions/points: Care needs to be taken with regard to purification of EVs. Are the FOXM1-DNAs in the EVs functional in recipient cells? Is the DNA being actively ‘selected’ for an intercellular signalling purpose or is this just random degradation? Is it all FOXM1 bound DNA that has the potential to be trafficked to EVs or just a subset? Do other transcription factors have the same function or is it specific to this protein/family? Does this mechanism occur in other contexts (e.g., in vivo, under disease conditions).

    1. We should think about the number of simultaneous connections (peak and average) and the message rate/payload size. I think, the threshold to start thinking about AnyCable (instead of just Action Cable) is somewhere between 500 and 1000 connections on average or 5k-10k during peak hours.
      • number of simultaneous connections (peak and average)

      • the message rate/payload size.

    1. Rather than write new tooling we decided to take advantage of tooling we had in place for our unit tests. Our unit tests already used FactoryBot, a test data generation library, for building up test datasets for a variety of test scenarios. Plus, we had already built up a nice suite of helpers that we coud re-use. By using tools and libraries already a part of the backend technology’s ecosystem we were able to spend less time building additional tooling. We had less code to maintain because of this and more time to work on solving our customer’s pain points.
    2. The problem domain and the data involved in this project was complicated enough. We decided that not having to worry about unknowns with the frontend end-to-end testing stack helped mitigate risk. This isn’t to say you should always going with the tool you know, but in this instance we felt it was the right choice.
    3. This particular project team came in with a lot of experience using testing tools like RSpec and Capybara. This included integrating with additional tools like Selenium WebDriver, Chrome and Chromedriver, data generation libraries like FactoryBot, and task runners like Rake. We had less experience doing end-to-end testing with Protractor even though it too uses Selenium WebDriver (a tool we’re very comfortable with).
    4. There are times to stretch individually and as a team, but there are also times to take advantage of what you already know.

      A truly enjoyable read about specific environmental factors and their effect on learning in adult zebra fish. Although the study was done on fish, it is known that this particular contaminant effects humans as well in many ways, including in intelligence. The fact that this contaminant was found to effect learning and memory in adult fish reminds us to consider multiple aspects when constructing educational environments. Physical location and learning environment can greatly impact adult learning outcomes and is rarely talked about in adult learning theory papers. 10/10 for interest, 1/10 for relevance to this class.

    1. Disappointingly, a recent meta-analysis failed to demonstrate any value for autologous platelet-rich plasma in the treatment of chronic wounds
    2. This approach allows treatment with patient-specific factors at an apparently physiologic ratio of growth factor concentrations.
    3. Autologous growth factors are harvested from the patient’s own platelets, yielding an unpredictable combination and concentration of factors, which are then applied to the wound.
    4. Fibroblasts stimulated by growth factors can produce type I collagen and glycosaminoglycans (e.g., chondroitin sulfates), which adhere to the wound surface to permit epithelial cell migration, as well as adhesive ligands (e.g., the matrix protein fibronectin), which promote cell adhesion.
