Bacteria act in groups to accomplish feats that are impossible to achieve if a single bacterium acts alone. For example, pathogenic bacteria act collectively to synthesize toxins to attack the host and to encase themselves in a shield that protects them from the host immune system and allows them to resist antibiotic treatment. To do this, bacteria communicate with each other with chemical “words", count their numbers, and act in synchrony when they have sufficient cell numbers for success. The award winners have discovered the dictionary and syntax underlying bacterial communication, opening up new and unprecedented opportunities to fight bacterial infections.

FRANKFURT am MAIN. Two American scientists, Bonnie L. Bassler and Michael R. Silverman, receive the 2021 Paul Ehrlich and Ludwig Darmstaedter Prize, which is endowed with 120,000 €. Bassler is Professor at Princeton University and a Howard Hughes Medical Institute Investigator, Michael R. Silverman is Emeritus Professor of the Agouron Institute in La Jolla. The two researchers are honoured for their ground-breaking discoveries concerning bacterial "quorum sensing", which refers to sophisticated systems of cell-to-cell communication that bacteria use to coordinate group behaviours. The award ceremony in St. Paul's Church, which is traditionally held on March 14, Paul Ehrlich's birthday, has been postponed due to the Coronavirus pandemic. Instead, Bassler and Silverman will receive the award at the ceremony in 2022.

"Silverman and Bassler have shown that, as for multicellular organisms, collective behaviour is the rule among bacteria, rather than the exception," wrote the Scientific Council in substantiating its decision. "Bacteria talk to each other, they eavesdrop on other bacteria, and they may even join forces. But: This ubiquitous chitchat, whose molecular underpinnings were discovered by Bassler and Silverman, also represents a previously unappreciated Achilles' heel in combating harmful microbes. Instead of killing bacteria with antibiotics, substances may be developed that interfere with bacterial communication effectively reducing their collective fitness. The prize-winners' research thus has considerable relevance for medicine".

Bacteria are extremely communicative. They send and receive chemical messages to find out whether they are alone or if additional members of their or other species are present in the vicinal community. To take a census of cell numbers, bacteria produce and release chemical signal molecules that accumulate in step with increasing cell numbers. When a threshold level of the chemical signal is achieved, the bacteria detect its presence. In response to it, in unison, bacteria undertake behaviours that are only productive when carried out in synchrony by the group, but not when enacted by a single bacterium acting in isolation. This chemical communication process is called quorum sensing and it controls hundreds of collective activities across the bacterial kingdom.

In the 1980s, Silverman discovered the first quorum-sensing circuit in the bioluminescent marine bacterium Vibrio fischeri. He identified the genes and proteins enabling production and detection of the extracellular signal molecule. He defined how the components functioned to promote collective behaviour. In the case of Vibrio fischeri, group-wide behaviour is the production of blue-green bioluminescence. Today, we know that quorum sensing is the norm in the bacterial world. Indeed, there are thousands of bacterial species that possess genes nearly identical to those discovered by Silverman. In all of these cases, these components allow bacteria to engage in group behaviours.

In the early 1990s, Bonnie Bassler proved that bacteria were “multilingual" and that they conversed with multiple chemical signal molecules. One communication molecule that Bassler discovered and named autoinducer- 2 enables bacteria to communicate across species boundaries. She went on to demonstrate that bacteria use quorum-sensing-mediated communication to differentiate self from other, showing that a sophisticated trait thought to be the purview of higher organisms, in fact, evolved in bacteria billions of years ago. In recent years, Bassler has shown that quorum sensing transcends kingdom boundaries as viruses and host cells, including human cells, engage in this ubiquitous chit-chat. She and other researchers also demonstrated that pathogenic bacteria rely on quorum sensing to be virulent. Bassler developed anti-quorum-sensing strategies that, in animal models, halt infection from bacterial pathogens of global significance.

“The full significance of the discoveries of the two laureates for microbiology and medicine has only recently been recognized," says Professor Thomas Boehm, Director at the Max Planck Institute for Immunobiology and Epigenetic and Chairman of the Scientific Council. "Decades of meticulous and painstaking work, showed that essentially all bacteria master the art of cell-to-cell communication," says Boehm. "What began with work on Vibrio fischeri and Vibro harveyi led to a fundamental change in perspective in bacteriology, and now opens up new and unprecedented opportunities in dealing with antibiotic resistance".

The 2021 Paul Ehrlich and Ludwig Darmstaedter Prize for Young Researchers 

Elvira Mass receives prestigious award for her research on organ development in mice 

The course for organ health is set in the early embryo. This year's laureate has shown that specialized immune cells from the yolk sac accompany organ development and contribute to maintaining their health throughout life. For Elvira Mass, impaired function of these immune cells might cause many diseases.

Frankfurt am Main. Developmental biologist Professor Elvira Mass, Ph.D. from the Life and Medical Sciences Institute (LIMES) at the University of Bonn, receives the 2021 Paul Ehrlich and Ludwig Darmstaedter Prize for Young Researchers, which is endowed with €60,000. The award ceremony in Paulskirche, which is traditionally held on March 14th, Paul Ehrlich's birthday, has been canceled this year due to the coronavirus pandemic. Elvira Mass will be honored next year together with the award winners of 2022.

For organs to stay healthy and functional, they must be constantly surveilled for abnormalities. Until a few years ago, it was believed that this task is performed by immune cells originating from the bone marrow. In a series of elegant genetic labelling experiments, Mass has shown that these cells are mainly yolk sac-derived progenitor cells that migrate to the developing organs, where they immediately differentiate and self-maintain for a lifetime. The reason for their longevity is still a mystery. These immune cells are referred to as tissue-resident macrophages and belong to our innate immune system. Their primary job is to scavenge anything that does not belong to a healthy organ. However, they also produce a broad range of bioactive molecules and growth factors, ensuring that tissues are not only 'tidy' but grow, develop, and function.

"The special achievement of Elvira Mass is to have contributed to an important change in perspective when looking at the function of organs," writes the Scientific Council, chaired by Professor Thomas Boehm, Director at the Max Planck Institute for Immunobiology and Epigenetics in Freiburg, in substantiating its decision. “In order to understand how organs develop and what keeps them healthy, one no longer only looks at the bone marrow, but also at the yolk sac and thus at a completely different population of macrophages. This observation has important implications for medicine, because organ-specific defects might be associated with malfunctioning tissue-resident macrophages originally derived from the yolk sac".

Mass has provided evidence for the health-promoting function of resident macrophages in the mouse brain. Her attempt to manipulate microglia, as the brain-specific macrophages are called, were stimulated by the findings in patients suffering from a rare form of cancer called histiocytosis. This cancer arises from mutated macrophages, which multiply out of control. Many patients suffering from histiocytoses eventually develop neurodegenerative symptoms or behavioural deficits. Mass introduced the mutation typical for histiocytosis specifically into yolk sac-derived tissue-resident macrophages of mice and followed the development of the animals. She found that the mutated microglia cells no longer carried out their traditional tasks but instead attacked and eliminated neurons in their vicinity. Eventually, this led to paralysis demonstrating that mutated microglia can cause neurodegeneration in mice.

With funding recently awarded by the European Research Council, Mass will investigate which environmental factors change the epigenetic imprinting of the yolk sac-derived tissue-resident macrophages and how these changes affect the health of organs. To this end, she will, among other things, examine the influence of nanoplastics on macrophages. Particles that are smaller than 500 nanometers enter the embryo's blood via the placenta and could potentially damage the supporting function of the tissue-resident macrophages.

Short biography of Professor Dr. Elvira Mass
Elvira Mass (34) studied biology at the University of Bonn and did her Ph.D thesis at the Life and Medical Sciences Institute (LIMES) in Bonn. In 2014, she moved to Frederic Geissmann's laboratory at King's College in London and followed him a few months later to the Memorial Sloan-Kettering Cancer Center in New York. From there she returned to the LIMES Institute in 2017 as a group leader. In 2019, she became W2 Professor for "Integrated Immunology" at the University of Erlangen-Nuernberg. In 2020, she switched to a W2 / W3 professorship at the LIMES Institute. Mass has received several awards, including the Heinz Maier Leibnitz Prize in 2020, which is considered the most important award for young scientists in Germany.

Collaboration between Goethe University and the University of Oklahoma

Quantum wave in helium dimer filmed for the first time

For the first time, an international team of scientists from Goethe University and the University of Oklahoma has succeeded in filming quantum physical effects on a helium dimer as it breaks apart. The film shows the superposition of matter waves from two simultaneous events that occur with different probability: The survival and the disintegration of the helium dimer. This method might in future make it possible to track experimentally the formation and decay of quantum Efimov systems (Nature Physics, DOI 10.1038/s41567-020-01081-3).

FRANKFURT. Anyone entering the world of quantum physics must prepare themself for quite a few things unknown in the everyday world: Noble gases form compounds, atoms behave like particles and waves at the same time and events that in the macroscopic world exclude each other occur simultaneously.

In the world of quantum physics, Reinhard Dörner and his team are working with molecules which – in the sense of most textbooks – ought not to exist: Helium compounds with two atoms, known as helium dimers. Helium is called a noble gase precisely because it does not form any compounds. However, if the gas is cooled down to just 10 degrees above absolute zero (minus 273 °C) and then pumped through a small nozzle into a vacuum chamber, which makes it even colder, then – very rarely – such helium dimers form. These are unrivaledly the weakest bound stable molecules in the Universe, and the two atoms in the molecule are correspondingly extremely far apart from each other. While a chemical compound of two atoms commonly measures about 1 angstrom (0.1 nanometres), helium dimers on average measure 50 times as much, i.e. 52 angstrom.

The scientists in Frankfurt irradiated such helium dimers with an extremely powerful laser flash, which slightly twisted the bond between the two helium atoms. This was enough to make the two atoms fly apart. They then saw – for the very first time – the helium atom flying away as a wave and record it on film.

According to quantum physics, objects behave like a particle and a wave at the same time, something that is best known from light particles (photons), which on the one hand superimpose like waves where they can pile upor extinguish each other (interference), but on the other hand as “solar wind” can propel spacecraft via their solar sails, for example.

That the researchers were able to observe and film the helium atom flying away as a wave at all in their laser experiment was due to the fact that the helium atom only flew away with a certain probability: With 98 per cent probability it was still bound to its second helium partner, with 2 per cent probability it flew away. These two helium atom waves – Here it comes! Quantum physics! – superimpose and their interference could be measured.

The measurement of such “quantum waves” can be extended to quantum systems with several partners, such as the helium trimer composed of three helium atoms. The helium trimer is interesting because it can form what is referred to as an “exotic Efimov state”, says Maksim Kunitski, first author of the study: “Such three-particle systems were predicted by Russian theorist Vitaly Efimov in 1970 and first corroborated on caesium atoms. Five years ago, we discovered the Efimov state in the helium trimer. The laser pulse irradiation method we’ve now developed might allow us in future to observe the formation and decay of Efimov systems and thus better understand quantum physical systems that are difficult to access experimentally.”

Statement by the authors

Researchers at Goethe University Frankfurt had recently reported in an article and a press release on the influence of the active substance loperamide on cell death in brain tumour cells. As a result, the German Brain Tumour Centres have received numerous enquiries about the therapeutic use of loperamide in patients with brain tumour diseases.

It should be noted, however, that the underlying research is based solely on cell culture models. Under no circumstances can recommendations for the treatment of humans be derived from the results. In addition to intestinal sluggishness, loperamide can cause severe and life-threatening side effects, especially when used in higher doses or not as intended.

The authors of the research article and the focus of neuro-oncology at the University Cancer Center (UCT) therefore strongly advise against the use of loperamide in brain tumour patients (beyond the indication of diarrhoea).

In cell culture, loperamide, a drug commonly used against diarrhoea, proves effective against glioblastoma cells. A research team at Goethe University has now unravelled the drug's mechanisms  of action of cell death induction and – in doing so – has shown how this compound could help attack brain tumours that otherwise are difficult to treat.

FRANKFURT. The research group led by Dr Sjoerd van Wijk from the Institute of Experimental Cancer Research in Paediatrics at Goethe University already two years ago found evidence indicating that the anti-diarrhoea drug loperamide could be used to induce cell death in glioblastoma cell lines. They have now deciphered its mechanism of action and, in doing so, are opening new avenues for the development of novel treatment strategies.

When cells digest themselves

In certain types of tumour cells, administration of loperamide leads to a stress response in the endoplasmic reticulum (ER), the cell organelle responsible for key steps in protein synthesis in the body. The stress in the ER triggers its degradation, followed by self-destruction of the cells. This mechanism, known as autophagy-dependent cell death occurs when cells undergo hyperactivated autophagy. Normally, autophagy regulates normal metabolic processes and breaks down and recycles the valuable parts of damaged or superfluous cell components thus ensuring the cell’s survival, for example in the case of nutrient deficiency. In certain tumour cells, however, hyperactivation of autophagy destroys so much cell material that they are no longer capable of surviving.

“Our experiments with cell lines show that autophagy could support the treatment of glioblastoma brain tumours,” says van Wijk. Glioblastoma is a very aggressive and lethal type of cancer in children and adults that shows only a poor response to chemotherapy. New therapeutic approaches are therefore urgently required. The research group led by van Wijk has now identified an important factor that links the ER stress response with the degradation of the ER (reticulophagy):  The “Activating Transcription Factor” ATF4 is produced in increased amounts both during ER stress and under the influence of loperamide. It triggers the destruction of the ER membranes and thus of the ER.

Anti-diarrhoea drug triggers cell death in glioblastoma cells

“Conversely, if we block ATF4, far fewer cells in a tumour cell culture die after adding loperamide,” says van Wijk, describing the control results. In addition, the research group was able to detect ER debris in loperamide-treated cells under the electron microscope. “ER degradation, that is, reticulophagy, visibly contributes to the demise of glioblastoma cells,” says van Wijk. The team also showed that loperamide triggers only autophagy but not cell death in other cells, such as embryonic mouse fibroblasts. “Normally, loperamide, when taken as a remedy against diarrhoea, binds to particular binding sites in the intestine and is not taken up by the bowel and is therefore harmless”.

Mechanism of action also applicable to other diseases

The loperamide-induced death of glioblastoma cells could help in the development of new therapeutic approaches for the treatment of this severe form of cancer. “However, our findings also open up exciting new possibilities for the treatment of other diseases where ER degradation is disrupted, such as neurological disorders or dementia as well as other types of tumour,” says van Wijk. However, further studies are necessary before loperamide can actually be used in the treatment of glioblastoma or other diseases. In future studies it has to be explored, for example, how loperamide can be transported into the brain and cross the blood-brain barrier. Nanoparticles might be a feasible option. The research team in Frankfurt now wants to identify other substances that trigger reticulophagy and examine how the effect of loperamide can be increased and better understood.

The research group led by Sjoerd van Wijk is funded by the Frankfurt Foundation for Children with Cancer (Frankfurter Stiftung für krebskranke Kinder) and the Collaborative Research Centre 1177 “Molecular and Functional Characterisation of Selective Autophagy” funded by the German Research Foundation (Deutsche Forschungsgemeinschaft). The work is the result of collaboration with Dr Muriel Mari and Professor Fulvio Reggiori (University of Groningen, The Netherlands) and Professor Donat Kögel (Experimental Neurosurgery, Goethe University).

Researchers at universities in Frankfurt and Tübingen have developed and empirically evaluated a new teaching concept for teaching secondary physics.

Newly developed curriculum improves students’ understanding of electric circuits in schools

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Physics Education Researchers at the Goethe University and the University of Tübingen have developed and empirically evaluated a new, intuitive curriculum as part of a major comparative study. The result: not only do secondary school students gain a better conceptual understanding of electric circuits, but teachers also perceive the curriculum as a significant improvement in their teaching.

FRANKFURT / TÜBINGEN. Life without electricity is something that is no longer imaginable. Whether it be a smartphone, hair-dryer or a ceiling lamp – the technical accomplishments we hold dear all require electricity. Although every child at school learns that electricity can only flow in a closed electric circuit, what is actually the difference between current and voltage? Why is a plug socket a potential death-trap but a simple battery is not? And why does a lamp connected to a power strip not become dimmer when a second lamp is plugged in?

Research into physics education has revealed that even after the tenth grade many secondary school students are not capable of answering such fundamental questions about simple electric circuits despite their teachers' best efforts. Against this backdrop, Jan-Philipp Burde, who recently became a junior professor at the University of Tübingen, in the framework of his doctoral thesis supervised by Prof. Thomas Wilhelm at Goethe University, developed an innovative curriculum for simple electric circuits, which specifically builds upon the everyday experiences of the students. In contrast to the approaches taken to date, from the very outset the new curriculum aims to help students develop an intuitive understanding of voltage. In analogy to air pressure differences that cause an air stream (e.g. at an inflated air mattress), voltage is introduced as an “electric pressure difference" that causes an electric current. A comparative study with 790 school pupils at secondary schools in Frankfurt showed that the new curriculum led to a significantly improved understanding of electric circuits compared to traditional physics tuition. Moreover, the participating teachers also stated that using the new curriculum fundamentally improved their teaching.

The two researchers from Frankfurt and Tübingen have now published a detailed description of the theoretical considerations underlying the teaching concept in the renowned international journal “Physical Review Physics Education Research" in the framework of the “Focused Collection: Theory into Design". The German Society for Chemistry and Physics Education (GDCP) awarded its “GDCP-Nachwuchspreis", a prize presented each year for the best dissertation or post-doctoral thesis in chemistry and physics education in the German-speaking region, to Burde for his dissertation. As of the winter semester 2019/20 Burde was appointed to a junior professorship for Physics Education Research supported by the Vector Foundation at the University of Tübingen. On the basis of his work a cross-border consortium encompassing the Universities Tübingen, Frankfurt, Darmstadt, Dresden, Graz and Vienna has been constituted with the objective of making the subject of “simple electric circuits" more interesting and more comprehensible by embedding the topic in contexts from daily life.
