Scientific theories are tested every time someone makes an observation or conducts an experiment, so it is misleading to think of science as an edifice, built on foundations. Rather, scientific knowledge is more like a web. The difference couldn’t be more crucial. A tall edifice can collapse – if the foundations upon which it was built turn out to be shaky. But a web can be torn in several parts without causing the collapse of the whole. The damaged threads can be patiently replaced and re-connected with the rest – and the whole web can become stronger, and more intricate. (Massimo Pigliucci)

1 | Feedback in Online tests

7 minutes
In Episode 36, Adam Rich called in regarding how we can provide feedback to students taking online tests. I responded that I encourage students to get the correct response from their study buddies—or from me. After the episode aired, Krista Rompolski pointed out that this could be a challenge in very large courses. What do y'all think? Tell us. Really.

2 | The Anatomical Compass

6.5 minutes
Although you and I are comfortable in orienting ourselves to anatomical directions when looking at diagrams, photographs, and specimens in anatomy, our beginning student often are not. The simple process of adding an "anatomical rosette" reflecting the anatomical directions in each encountered diagram can  help students develop the skill of understanding anatomical perspective.

4 | Reserve Hematopoiesis

3 minutes
Hematopoietic stem cells  (HSCs) may have a "back-up system" that helps out after damage to the working population. These "reserve" HSCs (rHSCs) may step up when the primed HSCs (pHSCs) cannot keep up with the demand for hematopoiesis.
  • Scientists have identified a bone marrow backup system (summary article)
  • N-Cadherin-Expressing Bone and Marrow Stromal Progenitor Cells Maintain Reserve Hematopoietic Stem Cells
    (report by Zhao, et al. in Cell Reports)

12 minutes
The "last best story" is what I tell my students I'm providing to them. That approach emphasizes the evolving nature of scientific understanding. In this episode, I mention two stories that are evolving right now.
