Federal and state funding of € 9.2 million for a long-term academy project at Goethe University and Friedrich Schiller University Jena
Approximately 40,000 letters from Martin Buber's correspondence with his contemporaries exist, but to this day, they have hardly been accessible. A funding commitment from the federal and state governments should now change this: an academy project for the digitalisation and annotation of this valuable estate will be funded with almost € 400,000 per year.
art, theology – Martin Buber, one of the most influential thinkers of the
modern German-Jewish intellectual world was in active exchange with the
representatives and institutions in almost every area of intellectual life.
More than 40,000 letters that were written by or to him have been handed down –
particularly in the philosopher's estate in Jerusalem, but also scattered
throughout archives around the world. Making this research treasure accessible
– that is the goal of the new academy project that Professor Christian Wiese, scholar
in the field of Jewish Studies and holder of the Martin-Buber-Chair in Jewish
Religious Philosophy at Goethe University, can now tackle thanks to the funds awarded
by the federal and state governments. All the letters are to be digitalised as
facsimile, and a large portion will also be transcribed, translated and
annotated. The project is designed for 24 years and will be funded with € 9.2
million, of which half will come from the Federal Ministry of Education and
Research and half from the Hessian Ministry of Higher Education, Research and
the Arts. Professor Martin Leiner (Friedrich Schiller University Jena),
Professor Abigail Gillman (Boston University) and the National Library of Israel
are cooperation partners.
“This is wonderful news." Professor Birgitta Wolff, President of Goethe University, is delighted about the grant. “With this academy project, Christian Wiese is setting new standards and planting the seed for a work that fits the time in every way," Wolff remarks, adding that the project is an important contribution to internationalisation in the digital humanities. “It is in fact quite special. There is nothing like it in other countries," says Professor Christian Wiese, who in 2019 concluded one of the last volumes of the edition of Martin Buber's published writings. The edition of the letters opens additional perspectives into Buber's life and work and his many interests – but also into intellectual life overall in the decades between the first World War and Buber's death in 1965. “Where, if not in Frankfurt, should this project have its home?" observes Wiese.
“The correspondence of Buber, who lived in Heppenheim and taught in Frankfurt, can contribute important new insights to the history of the twentieth century. Especially in our polarised time, we can learn a lot from the philosopher's approach, which always relied on dialogue and understanding. Christian Wiese's academy project is for this reason also an exceptional one in Hessen's research landscape in the humanities. I am very happy that we can co-fund this project and wish it great success," says Hessen's minister for Higher Education, Research and the Arts Angela Dorn.
Martin Buber (1868 – 1965) worked at the University of Frankfurt am Main from 1924 to 1933 – first as lecturer and later as honorary professor for Jewish religious teachings and ethics. He resigned from the professorship in 1933 after Hitler took power in anticipation of having his professorship revoked. He subsequently worked on setting up the Central Office for Jewish Adult Education with the Reichsvertretung of German Jews until it was forced to give up its work. Buber emigrated to Israel in 1938 before the November pogrom. Throughout his entire life, Martin Buber was in contact with personalities from all areas of intellectual life, including many writers such as Margarete Susman, Hermann Hesse, Arnold Zweig, Thomas Mann and Franz Kafka. Here, he did not shy away from controversial discussions. “The letters are a fascinating mirror of the time and reveal the intellectual network in which Buber was involved," says Christian Wiese. Perhaps a quarter of the letters were written by Martin Buber; the rest were written to him. But Martin Buber's personality and thought are reflected in these as well.
As part of the project, the letters, which are primarily located in Europe, Israel and the USA, are now to be collected and grouped according to thematic modules that stretch over several years, and made digitally accessible in close collaboration with the Academy of Sciences and Literature in Mainz. Depending on the content, transcripts and – where necessary – translations from the Hebrew along with annotations will be added. The academy project provides for three editorial positions and a doctoral scholarship. Annual conferences are planned, as well as intensive cooperation with researchers in Israel and the USA. The positions will be advertised soon so that work can start in the spring.
“Martin Buber and his work are more relevant than ever,“ says Professor Wiese with conviction. “He is one of the most important dialogic thinkers of the twentieth century, and his texts are relevant wherever intercultural or interreligious dialogue takes place. At the same time, they possess great meaning for issues of political ethics."

Research cooperation between Goethe University, University of Kent and the Hannover Medical School
In order for the SARS-CoV2 virus to enter host cells, its “spike" protein has to be cleaved by the cell's own enzymes - proteases. The protease inhibitor aprotinin can prevent cell infection, as scientists at Goethe University, the University of Kent and the Hannover Medical School have now discovered. An aprotinin aerosol is already approved in Russia for the treatment of influenza and could readily be tested for the treatment of COVID-19.
surface of the SARS-CoV-2 virus is studded with spike proteins. The virus needs
these in order to dock onto proteins (ACE2 receptors) on the surface of the
host cell. Before this docking is possible, parts of the spike protein have to
be cleaved by the host cell's enzymes – proteases.
In cell culture experiments with various cell types, the international scientific team led by Professor Jindrich Cinatl, Institute for Medical Virology at the University Hospital Frankfurt, Professor Martin Michaelis, and Dr Mark Wass (both University of Kent) demonstrated that the protease inhibitor aprotinin can inhibit virus replication by preventing SARS-CoV2 entry into host cells. Moreover, aprotinin appears to compensate for a SARS-CoV2-induced reduction of endogenous protease inhibitors in virus-infected cells.
Influenza viruses require host cell proteases for cell entry in a similar way as coronaviruses. Hence, an aprotinin aerosol is already approved in Russia for the treatment of influenza.
Professor Jindrich Cinatl said: “Our findings show that aprotinin is effective against SARS-CoV2 in concentrations that can be achieved in patients. In aprotinin we have a drug candidate for the treatment of COVID-19 that is already approved for other indications and could readily be tested in patients."

Scientists at Goethe University within the international consortium COVID19-NMR refine previous 2D models
Chemists at the University of Göttingen and Goethe University Frankfurt characterise key compound for catalytic nitrogen atom transfer
Catalysts with a metal-nitrogen bond can transfer nitrogen to organic molecules. In this process short-lived molecular species are formed, whose properties critically determine the course of the reaction and product formation. The key compound in a catalytic nitrogen-atom transfer reaction has now been analysed in detail by chemists at the University of Göttingen and Goethe University Frankfurt. The detailed understanding of this reaction will allow for the design of catalysts tailored for specific reactions.
FRANKFURT. The development of new drugs or innovative molecular materials with new properties requires specific modification of molecules. Selectivity control in these chemical transformations is one of the main goals of catalysis. This is particularly true for complex molecules with multiple reactive sites in order to avoid unnecessary waste for improved sustainability. The selective insertion of individual nitrogen atoms into carbon-hydrogen bonds of target molecules is, for instance, a particularly interesting goal of chemical synthesis. In the past, these kinds of nitrogen transfer reactions were postulated based on quantum-chemical computer simulations for molecular metal complexes with individual nitrogen atoms bound to the metal. These highly reactive intermediates have, however, previously escaped experimental observation. A closely entangled combination of experimental and theoretical studies is thus indispensable for detailed analysis of these metallonitrene key intermediates and, ultimately, the exploitation of catalytic nitrogen-atom transfer reactions.
Chemists in the groups of Professor Sven Schneider, University of Göttingen, and Professor Max Holthausen, Goethe University Frankfurt, in collaboration with the groups of Professor Joris van Slagern, University of Stuttgart and Professor Bas de Bruin, University of Amsterdam, have now been able for the first time to directly observe such a metallonitrene, measure it spectroscopically and provide a comprehensive quantum-chemical characterization. To this end, a platinum azide complex was transformed photochemically into a metallonitrene and examined both magnetometrically and using photo-crystallography. Together with theoretical modelling, the researchers have now provided a detailed report on a very reactive metallonitrene diradical with a single metal-nitrogen bond. The group was furthermore able to show how the unusual electronic structure of the platinum metallonitrene allows the targeted insertion of the nitrogen atom into, for example, C–H bonds of other molecules.
Professor Max Holthausen explains: “The findings of our work significantly extend the basic understanding of chemical bonding and reactivity of such metal complexes, providing the basis for a rational synthesis planning.” Professor Sven Schneider says: “These insertion reactions allow the use of metallonitrenes for the selective synthesis of organic nitrogen compounds through catalyst nitrogen atom transfer. This work therefore contributes to the development of novel ‘green’ syntheses of nitrogen compounds.”
The research was funded by the Deutsche Forschungsgemeinschaft and the European Research Council.

Synthetic vesicles are mini-laboratories for customised molecules
Cells of higher organisms use cell organelles to separate metabolic processes from each other. This is how cell respiration takes place in the mitochondria, the cell's power plants. They can be compared to sealed laboratory rooms in the large factory of the cell. A research team at Goethe University has now succeeded in creating artificial cell organelles and using them for their own devised biochemical reactions.
have been attempting to “reprogram" natural cell organelles for other processes
for some time – with mixed results, since the “laboratory equipment" is
specialised on the function of organelles. Dr Joanna Tripp, early career
researcher at the Institute for Molecular Biosciences has now developed a new
method to produce artificial organelles in living yeast cells (ACS Synthetic
To this end, she used the ramified system of tubes and bubbles in the endoplasmic reticulum (ER) that surrounds the nucleus. Cells continually tie off bubbles, or vesicles, from this membrane system in order to transport substances to the cell membrane. In plants, these vesicles may also be used for the storage of proteins in seeds. These storage proteins are equipped with an “address label" – the Zera sequence – which guides them to the ER and which ensures that storage proteins are “packaged" there in the vesicle. Joanna Tripp has now used the “address label" Zera to produce targeted vesicles in yeast cells and introduce several enzymes of a biochemical metabolic pathway.
This represents a milestone from a biotechnical perspective. Yeast cells, the “pets" of synthetic biology not only produce numerous useful natural substances, but can also be genetically changed to produce industrially interesting molecules on a grand scale, such as biofuels or anti-malaria medicine.
In addition to the desired products, however, undesirable by-products or toxic intermediates often occur as well. Furthermore, the product can be lost due to leaks in the cell, or reactions can be too slow. Synthetic cell organelles offer remedies, with only the desired enzymes (with “address labels") encountering each other, so that they work together more effectively without disrupting the rest of the cell, or being disrupted themselves.
“We used the Zera sequence to introduce a three-stage, synthetic metabolic pathway into vesicles," Joanna Tripp explains. “We have thus created a reaction space containing exactly what we want. We were able to demonstrate that the metabolic pathway in the vesicles functions in isolation to the rest of the cell."
The biotechnologist selected an industrially relevant molecule for this process: muconic acid, which is further processed industrially to adipic acid. This is an intermediate for nylon and other synthetic materials. Muconic acid is currently won from raw oil. A future large-scale production using yeast cells would be significantly more environment-friendly and sustainable. Although a portion of the intermediate protocatechuic acid is lost because the vesicle membrane is porous, Joanna Tripp views this as a solvable problem.
Professor Eckhard Boles, Head of the Department of Physiology and Genetics of Lower Eukaryotes observes: “This is a revolutionary new method of synthetic biology. With the novel artificial organelles, we now have the option of generating various processes in the cell anew, or to optimise them." The method is not limited to yeast cells, but can be utilised for eukaryotic cells in general. It can also be applied to other issues, e.g. for reactions that have previously not been able to take place in living cells because they may require enzymes that would disrupt the cell metabolic process.
