In the holiday rush, there were some fun science stories I was unable to get to other than the 2022 breakthrough of the year celebrating the ongoing JWST expedition. Now that we're back from celebrating with friends and family, let's check out some of what we missed!

As human beings with trillions of cells, each of which has their associated millions of copies of myriad proteins and other biological molecules, it’s something of a miracle that enough of the molecules bump together at the right times to keep us alive and functional. In addition to our own cells, we also coexist with microscopic neighbors, including various beneficial bacteria, while fending off pathogens like disease-causing bacteria, viruses, protozoans, and fungi. We often consider the bacteria and viruses in most human diseases, which invoke our immune systems to fight them to keep us healthy, but it also makes sense that the fungi can affect us as well, a topic in cancer research that is gaining attention.

When I taught high school biology, a favorite part of the curriculum was cellular structures and functions. I set up an activity suggested by other experienced biology teachers that was based on the “Cell City,” a learning analogy where students would create an artwork of a city with the mitochondrion as a power plant and a vacuole as a lake. (Figure 1) I wish I saved their very creative projects, but I distinctly remember one group used the Chicago Transit Authority’s elevated train system map to represent the endoplasmic reticulum (ER), a very clever use of the analogy and a nod to city pride. It was also the first time these students really thought about vesicular transport, although they didn't fully understand its importance.
