News from the Schwarz group
- As you might have seen above, we like to tweet on professional grounds. Follow @SchwarzUlrich
if you want to keep up-to-date with our interests and activities.
- In the academic year 2021/22, Ulrich Schwarz will be fellow of the Marsilius Kolleg, the center
for interdisciplinary studies of Heidelberg University. Together with Friedrich Frischknecht from Parasitology and Stefanie Gaenger from Global History, he will work
on the historical, biochemical and biophysical implications of fever diseases such as malaria and COVID-19.
- In the winter term 2021/22, we will offer lectures on stochastic dynamics (Ulrich Schwarz)
and non-equilibrium physics (Falko Ziebert) as well as an interdisciplinary seminar
on cell migration (Frischknecht, Schwarz, Selhuber-Unkel, Ziebert).

- On May 28 2021, Falko Ziebert from our group and Igor Kulic from Strasbourg have published a theory why
influenza virus can roll across glycan-coated surfaces by using the enzymatic activity of their surface receptors
(Physical Review Letters 126, 218101). This work has attracted considerably attention in different news outlets.
Here is a small collection: Physics (by Philip Ball),
science blog Laika und Freunde.
- The 7/2020 issue of the research magazine Ruperto Carola
is out on the subject of Maschine und Mensch. Here is the PDF of our text on Soft machines: what we can learn from biological cells

- Our lectures on Statistical Physics and Theoretical Biophysics both come
with scripts, which are especially useful if you consider to take the oral master exam on these lectures.
Check out more on our scripts website that has been
growing over the years into a (hopefully) helpful resource. For newcomers in our field we
recommend the up-to-date scripts on theoretical biophysics (our favorite),
statistical physics, stochastic dynamics and non-linear dynamics.
- For a general introduction into our work, we recommend the review by Ulrich Schwarz on the physics of cell adhesion
that appeared in the Physik Journal 7/2015 (in German). We also recommend the
youtube video of his talk on the physics of the cell by the DAI Heidelberg (in German) and our contribution to the 7/2020 issue of the research magazine Ruperto Carola
on Soft machines: what we can learn from biological cells (main text in German, but also a short version in English).

- Until Corona changed everything in early 2020, we maintained a list of upcoming conferences in our field.
Now this list has become an archive of
past conferences in soft matter and biophysics 2001-2020 (note that this was a private activity,
the collection is anecdotical and no claim to completeness is being made; conferences attended by
Ulrich Schwarz are marked in white color).

- In a broad collaboration between virology, cell biology, image processing, biophysics and mathematical biology
in the context of the collaborative research center 1129,
we were able to show that in the physiological environment of dense collagen gels,
HIV-1 spreads mainly by direct cell-cell contacts. The theory part included SIR-type kinetic modeling
of virus spread and a Cellular Potts Model for spatial spread in environments with obstacles. Read more in the corresponding
by Heidelberg University (German version).

- In order to predict the behaviour of single cells as well as of cell collective in structured
environments, we have developed a new version of the Cellular Potts Model that allows us to simulate
how cells dynamically position themselves on two-dimensional adhesive substrates. This work
was performed by Dr. Philipp Albert, financed by the EU-project MEHTRICS and published
in the high-ranking journal PLOS Computational Biology. Read more in the corresponding
