As antimicrobial resistance increases globally, infections with resistant bacteria pose a major public health threat. In a new study in Nature Catalysis, a team of researchers led by Adrian Bunzel from the Bioprocess Laboratory at D-BSSE and Christopher Frohlich from the Arctic University of Norway revealed a novel mechanism for how resistances can emerge alarmingly fast. The discovery may help create antibiotics that are less prone to resistance and guide personalized health care.
A leap forward for computer simulations of cellular tissues

Right from the early developmental stages to fully grown adults, brain cells continuously rely on mechanical cues to migrate to the correct locations in the body, form connections with other neurons or other cell types and communicate with them in a unique language of electrical impulses. In a new study, researchers from the Biophysics group of Daniel Müller and the Bio Engineering Lab of Andreas Hierlemann reveal how neurons sense the magnitude and temporal features of physical forces.
Understanding the pathology of neurodegenerative diseases
External
Neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal lobar dementia (FTLD) are difficult to study in vivo. A study led by the University of Zurich in collaboration with the Lab of Andreas Hierlemann, now identifies potential targets that may cause these diseases and their progression. The scientists developed a novel human-derived in vitro cell-culture model and methods for testing that the cells are functional, paving the way for new therapies.

Improving the environmental footprint of the textile industry: Bio-indigo for eco-conscious blue jeans
External
Only indigo gives denim its distinct blue colour. The dye is globally produced in quantities of up to 80,000 tonnes per year. However, its chemical production relies on fossil fuels, and some of the by-products are extremely toxic. After three years of research, scientists in Sven Panke's Bioprocess Lab have successfully developed a fermentation process for the synthesis of bio-indigo from renewable feedstock. The quality of this dye allows for direct application in industrial fibre staining.

Organisms and tissues develop through rounds of cell division, differentiation and death. Sophie Seidel and Tanja Stadler from the Computational Evolution group devised a new computational tool that quantifies these developmental processes from genetic footprints in single cells. Their work may contribute to a deeper understanding of development of model organisms and tissues, which in turn, can advance our insights into human development.

On the current list of Highly Cited Researchers, 21 have a connection to ETH Zurich. Tanja Stadler, Professor of Computational Evolution at D-BSSE, and three other ETH researchers appear on this list for the first time.
Universal structures for maximally robust biomolecular networks
External
To preserve their internal states, living systems often need to fully adapt to disturbances from their environment. This robust perfect adaptation (RPA) is ubiquitous in biology. In PNAS, Ankit Gupta and Mustafa Khammash from the Control Theory and Systems Biology lab characterise the universal internal network structures that control maximal RPA. Understanding these mechanisms is essential for a deeper understanding of biological regulation and for designing novel synthetic regulatory circuits.
Swiss public health measures associated with reduced SARS-CoV-2 transmission
External
In a new study in Science Translational Medicine, members of Tanja Stadler's group analysed thousands of SARS-CoV-2 genome sequences to reconstruct likely paths of viral transmission into and within Switzerland. Their results show that changes in transmission patterns can be associated with major public health measures. This large-scale analysis was enabled by a national genome sequencing effort initiated by Tanja's group as well as efforts from a broad collaboration of Swiss COVID researchers.

- Awards
With the Dandelion Entrepreneurship Award, the ETH Entrepreneur Club and ETH AI Center recognise faculty members who “encourage talented people to take a leap into the market”. Nominated by ETH students, PhDs and Post- Docs, Andreas Hierlemann receives the prize in 2022 in the D-BSSE. Well deserved: since 2008, the spinoff companies Zurich Instruments, InSphero, Shift Cryptosecurity, Validity Labs, and Maxwell Biosystems originated from his Bio Engineering lab. Congratulations, Andreas!

On 22 November, the Bioprocess lab is opening its doors, introducing the public to the great potentials of synthetic biology. This one-hour lab visit will be held in German, registration is required!
“We are in the process of building a Micro-and-Nano-Technology Hub here in Basel”
External
The Cleanroom is one of the core scientific facilities at D-BSSE. Once the Cleanroom has moved into BSS, the department’s new home, its size will have tripled, providing large-enough spaces and instruments to users from academic and industrial partners who fabricate devices at micro- and nanometre scales. Interview with Andreas Hierlemann, Liaison person for the Cleanroom Facility.
Last-resort antibiotics prepare E. coli membranes for disruption
External
Polymyxins are considered last-resort antibiotics which are still effective against multi-drug resistant pathogens. In a study published by Nature Communications, Selen Manioglu and colleagues from the Biophysics group and the Biozentrum, University of Basel, now describe their mechanistic effect at the molecular level. Using atomic force microscopy imaging, the results show that Polymyxins bond to membrane lipids and the newly formed crystalline structure weakens the membrane until it bursts.
Mapping human brain development
External
Researchers from the group of Barbara Treutlein are growing human brain-like tissue from stem cells and are then mapping the cell types that occur in different brain regions and the genes that regulate their development.
Testing drugs for cardiotoxic properties
External
Pharmaceutical compounds may have cardiotoxic properties, triggering potentially life-threatening arrhythmias. To investigate the effects of drugs on heart muscle cells derived from human stem cells, researchers around Andreas Hierlemann developed an electrophysiological technique for high-density microelectrode arrays, which enables to record intracellular-like signals. This technique may be routinely used in in vitro platforms for cardiotoxicity screening.
Engineering T-cell receptors for cancer immunotherapy
External
A study published by the Synthetic Immunology group of Sai Reddy presents a novel experimental and computational platform for engineering T-cell receptors. This work was led by Rodrigo Vazquez-Lombardi during his time as a postdoc at D-BSSE and became the foundational technology for the spinoff company Engimmune Therapeutics. Rodrigo has transitioned to the Chief Scientific Officer of Engimmune, which is applying the platform for engineering T cell receptors for cancer immunotherapy.
