"PhD students tend to choose a lab based on the topic, but a creative and supportive environment is more important. If everyone in the lab is miserable, you will probably be miserable there too; and if they are happy and thriving, you'll also likely feel good about yourself there."

1. Johann Gregor Mendel: Born to be a scientist?
   Eva Matalova: ”Johann Gregor Mendel, born 200 years ago, was supposed to be a farmer, intended to be a teacher, became a priest, turned to being a researcher, and later became a world famous scientist associated with genetics. Here, we look into his life through his own words.”

The newsletter now has a dedicated homepage where we post the cover artwork for each issue. We encourage submissions that coincide with the release of a recent paper from your group.

Caption: In our recent paper, we experimentally measured the frequency-dependent interactions between a gefitinib-resistant non–small cell lung cancer population and its sensitive ancestor via the evolutionary game assay. We showed that cost of resistance is insufficient to accurately predict competitive exclusion and that frequency-dependent growth rate measurements are required. Furthermore, using simulations, we demonstrated that incorporating ecological growth effects can influence the predicted extinction time. Together, our results highlight the potential importance of frequency-dependent growth rate data for understanding competing populations, both in the laboratory and as we translate adaptive therapy regimens to the clinic.
