From the editor:

One of my favorite quotes on creativity is “Every act of act of imagination is the discovery of likenesses between two things which were thought unlike.” (J. Bronowski) Much of the progress of modern day science is not necessarily new, as much as it is combining two existing concepts in a novel manner.

Our recent Cancer Research paper is no exception: we provide empirical evidence for antifragility in cancer. I stumbled upon the idea of antifragility in early 2018 when a (non-academic) friend told me that my explanation of Adaptive Therapy reminded him of a book he read by Nassim Taleb called Antifragile. Thus, the act of imagination was born, by observing the likeness between antifragility and adaptive therapy. The paper applies antifragility to targeted therapy by considering treatment schedules with a range of ‘dose volatility’ to define whether tumors are fragile (or antifragile) to induced volatility. Interestingly— the reviewers also suggested connecting our antifragility idea to existing ideas in adaptive (evolutionary) therapy, so we rewrote the Introduction in the final version. I hope you enjoy it, along with the other articles in this edition.

Enjoy,

The newsletter now has a dedicated homepage where we post the cover artwork for each issue, curated by Maximilian Strobl, Veronika Hofmann, Yifan Chen, and Sarah Groves. We encourage submissions that coincide with the release of a recent paper from your group. This week’s artwork:

Based on the paper: Trajectory Landscapes for Therapeutic Strategy Design in Agent-Based Tumor Microenvironment Models published in IEEE Control Systems Letters

Artists: Eric Cramer (LinkedIn), Laura Heiser (LinkedIn), Young Hwan Chang (LinkedIn)

Caption: The tumor microenvironment is an ecosystem whose state evolves over time, and that evolution traces a path across a landscape of possibilities. This map renders one such trajectory landscape: each colored basin is a metastable configuration our agent-based simulations settle into. The streamlines trace how the multicellular system as a whole meanders amongst them – doubling back on itself, changing direction, and eventually making its way towards immune control, exhaustion, or unchecked tumor growth. The compass rose marks key orientations – Initiation, Control, Exhaustion, and Escape – that the system can resolve toward. In our recent arXiv preprint (arXiv:2603.18333), this landscape becomes the substrate for state-aware therapy design via a switched Markov State Model, assessing where a tumor is and where it is poised to go next. A companion bioRxiv preprint (doi:10.64898/2026.03.26.714521) projects real multiplex tumor images from clinical trials onto the same landscape, linking spatial phenotypes to patient survival. Adobe Firefly was used to generate the stylized map, with refining and editing in Inkscape.
