Publication in PRL!

Our research article on stability of pattern formation in systems with dynamic source regions appeared last week in Physical Review Letters, The work is based on novel analytical framework developed by Maciej Majka. We showed that gene expression patterns can form stable domains with well-defined overlap region, yet without external feedback these domains can still shift. Thanks to analytical description we were able to provide stability conditions for all possible two-gene regulatory network motifs. This work has possible implications for fruit fly pattern specification, limb formation and spinal cord development.

Tomasz at Brainhack in Krakow

Tomasz hacked on the human brain’s diffusion MRI connectome in the first Brainhack held in Krakow between 21-23 October. It was a great opportunity to approach a new type of problem, explore a sizeable dataset with a variety of network analysis techniques and also to bring together the computational neuroscience community in Krakow!

Off-science discussion panel

Today we hold a second mtg in a series of discussion panels on non-scientific aspects of doing science. Together with Kasia Dziedzic-Kocurek we will moderate the discussion on how to keep work-life balance in academia and outside of it. We meet in Konfitura restaurant nearby campus at 17:30. The event poster has the list of invited panel attendees and further details.

Poster award

The poster by Maciej Majka on stability of gene expression patterns presented at international conference Diffusion Fundamentals IX received an award. In justification, the organizers highlighted that the creative application of physics research methods to problems of biological nature was highly appreciated.

DPG2022 in Regensburg

Last week Maciej Majka presented results on the stability of gene expression domains at the DPG Condensed Matter Section conference in Regensburg. The conference was great opportunity to attend broad range of Biophysics and Condensed Matter talks and network with other researchers!

Preprint on arXiv!

The latest results of Maciej’s project on how stable gene expression patterns are formed in systems with dynamic source regions are now available on-line at . Using a reaction-diffusion model with step-function production term, we identify phase transition between low-precision indeterminate patterning and the phase in which a well-defined contact zone between two domains is formed.
