Korean Studies at Goethe University receives € 700,000 to further develop its work / From 20 to 400 students in ten years
Korean Studies at Goethe University is one of what are known as “rare disciplines" (subjects with a small number of professors taught in only a few locations), so it is all the more impressive that it has now secured € 700,000 in third-party funding. The money is being invested in the project “Cultivating diversity: The global in Korea, Korea in the global" and should contribute to advancing teaching, research and regional collaboration in the field of Korean Studies.
FRANKFURT. Since 2010, there has been an area studies section at Goethe University dedicated to Korean Studies, hosted by the Institute of East Asian Philology. The number of students has risen from 20 at the outset to 400 today – and interest is continuing to grow, says Yonson Ahn, who, as the only professor for this subject, teaches Korean culture and society at the university. With the support of third-party funding, she can now better meet the growing demand for courses in this subject. The Academy of Korean Studies (AKS) has pledged around € 700,000 in funding for the next five years, which will be invested in research, teaching and outreach.
“I'm very pleased about this successful acquisition of third-party funds. Korean Studies is a rare discipline with considerable appeal. Thanks to Professor Ahn, Goethe University has made a name for itself in this field beyond geographical borders," says Professor Bernhard Brüne, Goethe University's vice president for research. The funds, provided by the South Korean Ministry of Education, are intended to boost Korean Studies abroad (from a Korean perspective – “Empowering Korean Studies through innovative education, research and regional cooperation in Germany"). Apart from Goethe University, the University of Oxford was the only other European beneficiary awarded funding in 2021. The Frankfurt research project deals with ethnic and cultural diversity in Korea and in Korean populations in other countries. The title is: “Cultivating diversity: The global in Korea, Korea in the global".
Funding approval was preceded by two successfully completed projects financed with third-party funds within the Seed Programme for Korean Studies, which each ran for three years – from 2015 to 2021. Their purpose too was research and the further development of the Korean Studies programme. Within the framework of the Korean Studies Promotion Programme of the AKS, Korean Studies at Goethe University has now qualified for the follow-up project “Core University Programme for Korean Studies", which will last five years – from June 2021 to May 2026.
In this project, Korean Studies in Frankfurt, headed by Professor Ahn, is working closely together with Korean Studies at the University of Hamburg under Professor Yvonne Schulz Zinda and Korean Studies at the University of Bonn under Junior Professor Nadeschda Bachem. The aim, in particular, is to establish a comprehensive cross-university network between the institutes in order to further develop teaching, support for early career researchers, public relations work and joint research projects, and in so doing also boost Korean Studies within the Interdisciplinary Centre for East Asian Studies (IZO) at Goethe University.
In the area of teaching, new seminars are to be designed and implemented within the framework of the project and digital teaching expanded. To support young students, the intention is to jointly supervise their master's theses and doctoral dissertations. In addition, there are plans to work together more closely with secondary school pupils. In order to make Korean Studies more visible, special attention will be given to public relations work. Low-threshold offers should facilitate access to topics in the field of Korean Studies.
A total of nine further researchers are working on a broad spectrum of interdisciplinary, transnational and intersectional topics in the framework of the project “Cultivating diversity: The global in Korea, Korea in the global" led by Yonson Ahn. Migration, gender, art and media, among others, are featured topics.
Goethe University remains Hessen's only university with a focus on area studies in Asian studies. After other Asia-related institutes were transferred to Frankfurt in 2008, the Interdisciplinary Centre for East Asian Studies (IZO) was established at the university. Since then, Korean Studies has grown in significance both qualitatively and quantitatively. Students can start the Korean Studies programme without any previous knowledge. Apart from the language itself, the programme also covers the country's politics, culture and literature. Professor Yonson Ahn attributes its great popularity to the success of Korean film and pop culture, such as the boy band BTS or the films Parasites and Minari, which have won Oscars as well as prizes in Cannes. Graduates definitely have good future prospects: Frankfurt is home to the second largest number of Korean expatriates in Europe, while a large number of Korean companies, a Korean trade agency (KOTRA) and a Korean consulate are located in the city.

Research team with Goethe University participation successfully proposes former quarry in Lower Saxony as Global Stratotype Section and Point
A team of scientists from Goethe University Frankfurt, the University of Warsaw, the State Authority for Mining, Energy and Geology (LBEG) in Hanover, and from other institutions world-wide, has found what researchers have been searching for worldwide for more than 20 years in Salzgitter-Salder: A geological formation that perfectly represents the transition from the Cretaceous Turonian to the Coniacian Age. The team has characterised the former limestone quarry so precisely that it is now considered a global reference point for the turn of the ages 89.4 million years ago. This was announced by the International Union of Geological Sciences, which awarded the stratotype profile the title "Global Stratotype Section and Point" (GSSP).
FRANKFURT/HANNOVER. The international team of geoscientists led by Prof. Silke Voigt from the Goethe University Frankfurt, Prof. Ireneusz Walaszczyk from the University of Warsaw and Dr André Bornemann from LBEG have thoroughly investigated 40 metres of the geological strata sequence in the former limestone quarry at Hasselberg. The researchers determined that this is only sequence in the transition between Turonian and Coniacian without gaps and it therefore represents a perfect rock sequence to serve geoscientists from all over the world as a reference for their research - a "Global Stratotype Section and Point (GSSP)" or, in the jargon of geosciences, a "golden nail".
Certain group of bivalve mollusks of the family Inoceramidae, first appeared in the Coniacian, and are found in large numbers in Salder. In Bed 46 of the quarry, the German-Polish scientific team found the oldest appearance of the Inoceramid species Cremnoceramus deformis erectus, which marks the time boundary. Careful studies also revealed other microfossils and a characteristic change in the ratio of the carbon isotopes 12C and 13C, a so-called negative anomaly in the carbon cycle.
"This means that variable geological sequences, such as marine shelf sediments in Mexico or the deep sea in the tropical Atlantic, can now be compared and classified in time," explains Prof. Silke Voigt. "This is important in order to be able to make an exact chronological classification even in the case of incomplete successions and ultimately to see, for example, what the climate was like at a certain time in the past in different places in the world."
Professor Ireneusz Walaszczyk says: "The sequence in Salzgitter-Salder prevails over other candidates, for example from the USA, India, Madagascar, New Zealand and Poland, because we have a perfect rock boundary sequence here over 40 metres, with a well-defined record of events which took place in this interval of geological time."
"The Zechstein Sea left behind massive salt layers in the North German Basin more than 250 million years ago," explains André Bornemann. "The rock layers deposited later exerted pressure on these salt layers, some of which bulged up into large salt domes, deforming younger layers in the process. Salder is located near such a salt dome, so that here the fossil-rich rock layers of the Cretaceous period are steeply upright, resulting in a wonderful profile that is very accessible for scientific investigations. That's why we at LBEG have designated this place as a geotope, and this is one of the most important geopoints of the Harz-Braunschweiger Land-Ostfalen UNESCO Global Geopark."
In the limestone quarry at Hasselberg near Salder in the north-east of the Salzgitter mountain range, limestone and marl used to be quarried for the cement industry and later for ore processing. Today, it is the location of a well-known biotope and geotope which is the property of the Stiftung Naturlandschaft (Natural Landscape Foundation) and established by the BUND regional association of Lower Saxony. While the care of the quarry site has been entrusted to the Salzgitter district group of BUND, the Harz-Braunschweiger Land-Ostfalen UNESCO Global Geopark looks after the geoscientific part of the quarry. The quarry is not freely accessible for nature conservation reasons, but guided walks are occasionally offered.
90 million years ago, in the second half of the Cretaceous, it was tropically warm on Earth: the ice-free poles ensured high sea levels, and Central Europe consisted of a cluster of islands. In the sea, ammonites developed a tremendous variety of forms, while dinosaurs reigned on land. The first flowering plants began to compete with horsetails and ferns. About 89.39 million years ago, the climate began to cool slightly, sea levels began sink, and a new period in Earth history, the Coniacian, replaced the Turonian.

Researchers at Goethe University find small molecules as binding partners for genomic RNA of the coronavirus
Certain regions of the SARS-CoV-2 genome might be a suitable target for future drugs. This is what researchers at Goethe University, together with their collaborators in the international COVID-19-NMR consortium, have now discovered. With the help of dedicated substance libraries, they have identified several small molecules that bind to certain areas of the SARS-CoV-2 genome that are almost never altered by mutations.
FRANKFURT. When SARS-CoV-2 infects a cell, it introduces its RNA into it and re-programmes it in such a way that the cell first produces viral proteins and then whole viral particles. In the search for active substances against SARS-CoV-2, researchers have so far mostly concentrated on the viral proteins and on blocking them, since this promises to prevent, or at least slow down, replication. But attacking the viral genome, a long RNA molecule, might also stop or slow down viral replication.
The scientists in the COVID-19-NMR consortium, which is coordinated by Professor Harald Schwalbe from the Institute of Organic Chemistry and Chemical Biology at Goethe University, have now completed an important first step in the development of such a new class of SARS-CoV-2 drugs. They have identified 15 short segments of the SARS-CoV-2 genome that are very similar in various coronaviruses and are known to perform essential regulatory functions. In the course of 2020 too, these segments were very rarely affected by mutations.
The researchers let a substance library of 768 small, chemically simple molecules interact with the 15 RNA segments and analysed the result by means of NMR spectroscopy. In NMR spectroscopy, molecules are first labelled with special types of atoms (stable isotopes) and then exposed to a strong magnetic field. The atomic nuclei are excited by means of a short radio frequency pulse and emit a frequency spectrum, with the help of which it is possible to determine the RNA and protein structure and how and where small molecules bind.
This enabled the research team led by Professor Schwalbe to identify 69 small molecules that bound to 13 of the 15 RNA segments. Professor Harald Schwalbe: “Three of the molecules even bind specifically to just one RNA segment. Through this, we were able to show that the SARS-CoV-2 RNA is highly suitable as a potential target structure for drugs. In view of the large number of SARS-CoV-2 mutations, such conservative RNA segments, like the ones we've identified, are particularly interesting for developing potential inhibitors. And since the viral RNA accounts for up to two thirds of all RNA in an infected cell, we should be able to disrupt viral replication on a considerable scale by using suitable molecules." Against this background, Schwalbe continues, the researchers have now already started follow-up trials with readily available substances that are chemically similar to the binding partners from the substance library.

Goethe University study on student learning outcomes during COVID-19-related school closures in spring 2020
How effectively do children and teenagers learn in remote classes from home? The issue has been the subject of intensive discussions, not only among experts. A systematic review from the Department of Educational Psychology at Goethe University provides a sobering answer for the spring of 2020. The situation seems to have later improved.
FRANKFURT. Despite diverse efforts to continue school operations as far possible with the help of remote learning and digital options during COVID-19-related schools closures, large deficits came about in the learning progress of many students. This was shown by a systematic review from Education Psychology at Goethe University. In the course of this systematic review, scientific databases were used to identify studies worldwide that examined the effect of COVID-19-related school closures on student achievement.
“We only included publications with appropriate research methods that allow evidence-based conclusions about the effect of COVID-19-related schools closures on student achievement, and that used testing instruments that are suitable for measuring student achievement," explains Professor Andreas Frey, who teaches Educational Psychology with a focus on consulting, measurement and evaluation at Goethe University, and is one of the authors of the study. This showed that, compared to pre-COVID-19 in-person teaching, average student achievement was significantly lower during school closures. “The average student achievement during the school closures in the spring of 2020 is best designated as stagnation, with a tendency toward losses comparable in size to the effect of summer vacation," says Frey. Observed losses in learning were particularly distinct for students from socio-economically disadvantaged homes. “The empirical evidence supports previous assumptions: The gap between rich and poor widened even more during the first COVID-19-related school closures," concludes Frey. However, there are also initial indications that the effects of the later school closures from winter 2020/21 onwards may not necessarily be as drastic. Online teaching has improved in many places, which seems to mitigate the negative effects.
The systematic review written by Svenja Hammerstein, Christoph König, Thomas Dreisörner and Andreas Frey is available as an open access preprint at https://psyarxiv.com/mcnvk/. The work is part of the project "Identifying and Reducing COVID-19-related Educational Disadvantages" (CoBi), which is funded by the Beisheim Foundation and the Goethe Coronavirus Fund. In the CoBi project, an online screening tool is being developed to identify particularly at-risk secondary school students, who are then supported by the MainKind counselling centre at Goethe University.

Screening of multiple gene mutations is also applicable for complex nervous and immune diseases
An extended application of the CRISPR-Cas technology has been made possible by Dr Manual Kaulich's team at Goethe University: the new 3Cs multiplex technique allows the effect of genetic changes in any two genes to be studied simultaneously in cell cultures. This can provide important clues for the development of therapies to treat cancer or diseases of the nervous and immune systems.
FRANKFURT. Cancer and many other diseases are based on genetic defects. The body can often compensate for the defect of one gene; it is only the combination of several genetic errors that leads to the clinical picture. The 3Cs multiplex technique based on CRISPR-Cas technology developed at Goethe University Frankfurt now offers a way to simulate millions of such combinations of genetic defects and study their effects in cell culture. These "gene scissors" make it possible to introduce, remove and switch off genes in a targeted manner. For this purpose, small snippets of genetic material ("single guide RNA") are used as "addresses" that guide the gene scissors to specific sections of the DNA, where the gene scissors then become active.
The scientists from the Institute of Biochemistry II at Goethe University have expanded the 3Cs technique that they developed and patented three years ago. 3Cs stands for covalently-closed circular-synthesised, because the RNA elements used for CRISPR-Cas are generated with the help of a circular synthesis and are thus distributed more uniformly. With a whole library of such RNA rings, any gene in a cell can be specifically addressed in order to change it or switch it off.
The new 3Cs multiplex technique now even allows the simultaneous manipulation of two genes in one cell. Dr. Manuel Kaulich explains: "We can produce 'address' RNA libraries for all conceivable two-gene combinations. This allows up to several million combinations to be tested simultaneously in one experiment."
Until now, the cost and effort of such experiments was very high; the research group's new technique reduces it, including costs, by a factor of ten. This is because the team can produce the address libraries very uniformly and in high quality thanks to the new 3Cs multiplex technique. "Due to the mediocre quality of the CRISPR-Cas libraries previously available, very large experiments always had to be carried out to statistically compensate for any errors that arose," says Kaulich.
Using the example of various genes involved in degradation processes, the research group demonstrated the potential of the new 3Cs multiplex technique: they examined almost 13,000 two-way combinations of genes that are responsible for recycling processes (autophagy) in the cell. With their help, the cell breaks down and recycles "worn-out" cell components. Disturbances in autophagy can trigger cell proliferation.
"Using the 3Cs multiplex technique, we were able to identify, for example, two genes involved in autophagy whose switching off leads to an uncontrolled growth of cells," explains Kaulich. "These are precisely the autophagy mutations that occur in every fifth patient with squamous cell carcinoma of the lung. In this way, we can search very efficiently in cell culture experiments for genes that play an important role in cancer, and also in diseases of the nervous and immune systems, and that are suitable as possible targets for therapies."
The Goethe University research group has applied for a patent for its developments through the university's technology transfer subsidiary Innovectis. The start-up company Vivlion GmbH, spun off from the Institute of Biochemistry II with the participation of Manuel Kaulich, is already offering the use of this technology on the market.
