For decades our attention has been focused on how learning works. However, at the beginning of 2025 it might be more important to shift our focus of learning research on “not learning”. Recent research on learning includes the study of “social learning” of mice (Winiarski et al. 2025) and the related brain mechanisms that are involved in social learning like the prelimbic cortex.
For our human societies we also rely to a great deal on social learning. In mice, however, the disruption of the prelimbic cortex causes mice to no longer seek “social information related to rewards” from other mice. In Eco-HAB cages these mice follow their scent capabilities to “sort” their information seeking from for example higher “social status animals”. This tested reward seeking behavior allows clues to how learning works. The intervention to disrupt the synaptic plasticity in a later phase of the experiment reveals less social learning from the network social information and fewer contributions to the social network.
Only intact neural plasticity in the prelimbic cortex ensures the maintaining of the social structure. Of course it is highly questionable, whether these results based on animal experiments tell us anything about social structure and social learning in other mammals, but there might be reasons to search for explanations of “no social learning” in humans as well. 
Wellness Sickness
There appears to be some kind of a relationship between the 2 conepts of wellness and sickness. Some would argue that the more sick you are, the more you seek wellness. Sickness seems to be the precursor of wellness for many people. Wellbeing or happiness are even higher order concepts which are only indirectly related to wellness. In an almost 600 pages science and fiction novel, Nathan Hill (Link) constructs his plot based on the psychological research on the placebo effect. With a sufficient aura around a pseudo-medication administered in a wellness clinic, the clients or some figure near the 50% random positive effects are treated with at least no negative side effects. On page 152 we find the more explicit description of how to induce a placebo effect in participants. Context, expectations, faith, symbols, metaphors and story are all ingredients for a placebo effect to work. Sometmes without knowing we receive a treatment in our childhood or throughout the life course that we work on using placebo effects to overcome them. The novel by Hill (2024) is a well researched psychological as well as sociological fiction including a bibliography, which reminds us „If you cling too hard to what you want to see, you miss what’s really there.“ (p. 496). 
Review Year
It is a nice common practice to wish „A happy New Year“ to people at the beginning of another calendar year. It is also a good practice to review the last twelve months yourself or with friends. We spend,however, much less time to listen to friendly or enemy fire as a kind of evaluation of what were the successes and failures of last year. In monarchies in the middle ages a clown or a fool was allowed to present criticisms with funny packaging. Nowadays, comedians have taken over this important role to review experiences and policies that worked or went awfully wrong. All media join in in this tradition and summarize what happened before the next busy months take over. Yes, it is important to devote time to this procedure. There is a risk that it becomes „the same procedure as every year“, but it is never to late to learn from failures or simple mistakes. Failed last year, fail better next year. 
Investment Disinvestment
Asume we live in a world of fixed amounts of investments. The option to invest in a new project or product will automatically reduce the amount of investment in another product. The investment decision, therefore, is subject to opportunity costs. A recent study by Naci et al. (2025) applies this rationale to the investment in new drugs compared to financing other traditional treatments. The results for the U.K between 2000 and 2020 revealed that the „quality-adjusted life-years (QALYs)“ is not in favor of the investment in new drugs. The relatively small numbers of beneficiaries of the new drugs is compared to the many other persons who could have benefited from the less costly previous treatment. Investment in one new drug causes disinvestment in other ones. The overall balance for the UK turned out to be negative. Particularly the disinvestment in prevention of diseases appears to have very detrimental effects in view of the results based on this study. Preventative measures are relatively cheap compared to the estimated 20.000 pounds for one additional quality adjusted year of life for a new drug. The message is: choose your health investments wisely to avoid ever rising health costs and health insurance. (Image: rest room Belgium) 
Animal Longevity
- From time to time it is interesting to study animals from many species to maybe learn from them about longevity. Roberto Salguero-Gómez (LINK) developed a sociality continuum and compared 152 species across 13 taxonomic classes. The study reiterates and generalizes the many studies of single species and finds that „more social species live longer, have more generation time and longer reproductive windows“. Social structures amongst animals of the same species influence survival and reproduction as basic demographic processes. These processes determine to a large extent the size of animal populations. Sociality appears to be a major contributor to longevity compared across species. These processes determine the survival of rather solitary species like panda bears (running higher risks of extinction) compared to populations of bees with rather hierarchical predefined social structures. The spotted hyenas developed cooperative hunting and communal care which allows for effective survival compared to other species. Sociality is specific to species and therefore largely determined by genetic factors. Nature rather than nurture is at work. However, species where reproduction occurs later allow for learning curves of sociality. In other words even within species there is scope to improve longevity through sociality. Migration patterns or experience with migration might be yet another determinant of survival or longevity as climate change poses new challenges to many species.
No tobacco Sweden
Sweden is the forerunner as country with the lowest number of smokers across Europe and probably even the world with only 5% of the population 16 years and older. The success of these public health policies is due to banning smoking not only form pubs and restaurants, but also outside in the surroundings of public spaces like schools, playgrounds, train stations and sports facilities. These policies work quite well and the effects of discouraging smoking in public is reduced to a minimum rather than the normal encounter.
Health of the other persons and children passing through these areas is not the only goal. A new estimate of lost days or years due to smoking based on a study from England shows that “each cigarette smoked reduces the smoker’s life by about 20 minutes (17 for men, 22 for women, LINK to study). Of course, there is a huge variance and other work and life conditions that play an important role as well, but the broad average estimate is a nice way of talking about statistics. The basis of the estimate is for those who stop smoking and not those reducing their tobacco intake by some percentage or replacement product.
In the Belgian football stadium (image below 2024) in Brussels the No tobacco sign is well placed to make parents of children and youth understand the challenge ahead. Good resolutions are assisted by gentle regular reminders as well. 
More Battles
In 2025 we continue with the same battles as in the previous year. However, the way armies fight military battles has evolved. New types of weapons like drones have entered the stage. These precision weapons (Horowitz, 2024) have the advantage to be not only less costly than other heavy mass and costly artillery, they can also be guided in swarms to their targets. A further advantage is the steering of drones needs differently qualified persons rather than advancing with heavy armored vehicles on battlefields. Upskilling of defense forces is an important side effect. Jamming technology of radio frequencies was applied before, nowadays this has turned into a crucial defense strategy to intercept and derail drones and rockets off their intended targets.
Other than heavy weight arms, even laser beams enter the arsenal of weapons, if targets are sufficiently static in nature. These high-energy beams are still more in the research and testing realm rather than used on the battle field, but it becomes clear that research capacities play and played an important role throughout military history. The next generation of robots, not only in production processes, but more those walking on the battlefields is likely to change wars to less manned interventions. The technological innovations shall further move the spiral of new generations of weapons forward. Fewer soldiers, but more robots in the air, at sea and on the ground might increase the risks of “restrained”, less costly, but longer duration conflicts across the globe.
I always thought of robots as rescue robots to save lives. The flip side of the coin, however, is destruction before rescue as well. Technology can be put to both purposes. It is us who decide, which one takes the upper hand. 
EU Georgia
It is a moving image to see a hundred demonstrators at „Unter den Linden“ in Berlin just next to the Russian Embassy. The Georgian flag and Georgian people actively seek the association with the European Union and the values it stands for. Irrespective of a large majority of the people of Georgia‘s wish to become part of the EU they have to fight hard to be heard. Next to the Ukranian protests in Berlin it becomes very evident that these two nations fight for living standards and values which are so „self-evident“ for us European citizens that it is all to easy to forget about our neighbors who have to endure hardships with uncertain outcomes. The experience of having lived together under one roof with people from other countries allows to realize that we have so much more in common than what separates us. Our house and home of the EU has much to offer, more than we tend to believe in our daily routine. 
Happy Year
- Happy Past Year? Happy New Year! Happiness is the driving force behind most endeavors for all people beyond the needs of subsistence. Even if many believe that money makes the world go round, the thrive for happiness is soon overriding the comparatively simple pleasures money can buy. A Bistro in Berlin in the middle of a park has the entry reception entitled „zum Glück“. An excellent wish for the New Year and a chance to review the „glückliche Momente“, the happy moments of last year.
Career Criminals
From a life course perspective it is not easy to define a colloquial term like career criminal. A person who has been convicted for a single crime and has served his/her sentence should be allowed full integration into society. Even a repeated offender should not be stigmatized or labeled as career criminal. However, this is exactly what the NS-state did (traveling exhibition across Germany and Austria: „Die Verleugneten“). These persons were subject to targeted charges for criminal offenses they „might“ commit eventually. The term „community alien“ or „asocial“ were also used to refer to persons that did not fit into the dominant Nazi doctrine of „Volk“. It took 75 years until these persons could receive a recognition and a recompense for their unfounded discrimination and incarceration. In concentration camps the so-called asocial or career criminals were at the highest risk of further prosecution and death. Great that the stumbling Stones include these victims as well, as a way to remember these crimes against humanity. Beware of definitions of social groups which are based on totalitarian ideologies. 
Zerreissprobe
The term „Zerreissprobe“ has been chosen by the curator team of the Neue Nationalgalerie In Berlin for the Retrospective of „Art between politics and society“ in the years 1945-2000. In this time period after the 2nd World War until the other „fin du siècle“ the politics of creating a new world order, the cold war and the liberalization of societies had profound impacts on art as well. The positioning of art in the dynamic context and conflicts of these decades is quite well reflected in the title of the exhibition. The English title „extreme tension“ suggests somehow that these years were rather extreme compared to ?, probably today? Although on the territory of Ukraine we witness a hot war rather than a cold war initiated by Putin‘s Russian imperial illusions. The cited work of Günter Brus „Zerreissprobe“ is translated as „stress test“. And maybe, this translation characterizes the post war period even better as these years are a forerunner of what happened after 2000. We continue to be put to tests in politics and societal developments. Accomplishments from the last century are put to crude tests again. Solidarity of people and nations are under pressure to demonstrate their reliability under extreme tension or stress. Art throughout the 5 decades of the last century was a precursor of stress tests for politicians and challenged society in its basic understandings. The comments on the notice board next to the exhibition show the themes of tension in the 2020s. Tensions in families and partnerships, often more extreme around christmas trees, have taken center stage for younger visitors of the exhibition. Sociological research has observed such trends and coined this societal phenomenon „individualization“. Art embedded in society seems to be part of that evolution as well. Art movements are less visible as collective movements. Artists appear more individualistic or ideosyncratic nowadays, just less inclined to be part of a defining larger group. If artists are no longer avantgarde but rather followers of societal trends, the whole „raison d‘être“ of art changes as well. We are likely to witness yet another „ Zerreissprobe“. Cuts to art and culture budgets constitute an additional „ Zerreissprobe“ in the original sense of the word and of art between politics and society in 2024/2025. 
Films of Stills
The exhibition of multimedia artist Nan Goldin at the Neue Nationalgalerie (New National Gallery) in Berlin presents a retrospective of her work using slideshows of stills including soundtracks (Image below). The topics and narratives range from autobiographical work on own traumatic experiences to works entitled „memory lost“. The sequences of stills are a form to deal with trauma through art like overcoming the suicide of a family member. Drug or sexual dependency enter the stills and it becomes clear that stillness is part of the coping mechanism she employs. It is hard to watch, sit still and endure the films of stills. However, there is a kind of therapeutic experience to be gained in coping with trauma through art. The installation in several tents increases the reclusive atmosphere and entering the still rooms invites is, somehow including a warning of what kind of chilling experience we are up to throughout the exhibition. The almost therapeutic experience needs to be handled with care and a visit with friends or family is highly recommended in my view. Community and communication are key to coping with these experiences and even still images contribute to building resilience. 
Cumulative Mandates
Since 2010 and with 18 volumes the documentation of perpetrators assistants free riders during the Nazi rule in Germany has been valuable and reliable source of information (Kugelberg Verlag). The book series defines the perpetrators as the persons excuting crimes themselves or were in command of those who committed the crimes or gave orders to do so. It is not surprising to find evidence of many crimes, but rather that it took such a long time until the documents were published and the descendants were confronted with the facts and the difficult heritage. There are still many who undertake all efforts to deny the facts or try to minimize the guilt of perpetrators. With the real dangers of new right-wing extremism on the rise across Europe and even beyond, it becomes more important to uncover the strategies and biographies of the perpetrators. Certainly the members of the SS were executives and in command of atrocities, so-called NSDAP party officials were also mostly convinced followers of Nazi doctrines and instrumental in the implementation of crimes. Additionally, several professions (line soldiers or medical doctors) were key in the process to ensure the power of the totalitarian regime until the final days. Some persons were cumulating roles and became thereby inescapable spiders in a web of control and crimes. The lessons for today consist in hindering excessive cumulation of mandates, political, professional, military and in other work or civil society related functions. Distribution of power is one form to safeguard the survival of democratic structures. 
Conducter Careers
The careers of conductors during the 1930s and 1940s have been propelled by joining the NSDAP on Germany. Even if not too outspoken as conductors on Nazi discriminatory policies many openings arose only due to banning Jewish conductors and musicians from performing in public. The acceptance of vacancies due to such restrictions advanced the careers of Karl Böhm as well as Herbert von Karajan. A theatre play Böhm at the Deutsches Theater in Berlin takes up this topic and puts the professional career in perspective of an anti-humanist leadership style. Karajan has also come into critic, because of his role in selecting musicians who were conform to the prevailing Nazi-antisemitism. It is important to work on these biographies and their implications for hundreds of lives of other musicians. Many careers have been destroyed due to these two prominent conductors ready to do almost anything to advance their careers. It puts their interpretation of music in a different light knowing about their instrumentalist approach to music, their own careers and the disrespectful Nazi doctrines.

Victim Perpetrator
Research on the Shoa and the Nazi crimes has a clear cut separation into millions of victims and millions of perpetrators. There is only a very small group of persons who risked their lives in their attributed or chosen role of perpetrators and saved lives. Most of those persons received recognition later, some decades later. The vast majority of persons were oblivious to their prior roles and some even tried to defend them themselves through a variant of victim blaming in recurrent attempts to reduce their guilt. Another frequent excuse is to recur to a perpetrator’s own experience as a victim of abuse or tough childhood. In a static perspective this might work, but the learning and reflection ability of humans apply to all persons irrespective of age, if they show the willingness to do so. victimization is powerful tool to justify a role as perpetrator later on. Criminal courts assisted by psychologists statements accept guilt reduction. After all those considerations the basic classification into victim or perpetrator remains a valid differentiation, only very few cases allow for a more nuanced assessment of the case.

Nazi Doctors
The role of medical doctors during the Nazi domination in Germany has been revisited by the professional organization of statutory medical doctors (Kassenärztliche Bundesvereinigung KBV) in collaboration with the Center for Research on Antisemitism (ZfA TU Berlin). The exhibition entitled „Systemic Disorder“ first shown in the main entrance hall in front of a conference room offers a thorough review of the role of medical doctors throughout the Nazi period. Politically undesirable physicians were rapidly banned from the profession and promotions given to NSDAP party members. The totalitarian approach transformed the whole apparatus of the medical profession into a politically streamlined organization ready to commit crimes like forced euthanasia or selecting „insane“ persons for special medical treatments in other institutions. Selection of forced laborers for firms or declaring them unfit for work, which in many cases sent those persons to concentration camps, was part of the streamlined medical doctors. It took decades after the „Wehrmachtsausstellung“ in Hamburg that another profession has done its homework. Great to know that this important exhibition, documentation and catalog is traveling now across Germany for at least a year. It is another milestone in coming to understand how presumably intelligent people were part of a highly efficient selection and killing machine during the Nazi domination in Germany.

Question Tomorrow
« Tomorrow is the question ». This is the imprint on the 8 table tennis tables in the Martin Gropius Bau 2024. As part of the Contemporary art exhibition by the artist Rirkrit Tiravanija, the tables are very busy throughout the day and invite people to meet, play and greet. If tomorrow is the question, today is the answer. Is it? Maybe the answer is the day after tomorrow? Time appears to be the answer and the question. Such questions touch on basic philosophical questions about our relationship to and concept of time. Future orientation or even the belief in life after death touch upon basic religious beliefs. Intergenerational transmission is useless if there is no tomorrow or concept of tomorrow. Sustainability is most relevant if we are convinced there will be a tomorrow. Fatalists or warmongers rate today so much more than tomorrow that everything is subordinated to the urgency of now. Not easy to strike the right balance between „for now“ and „for tomorrow“. Simple financial discounting of benefits which accrue only tomorrow do not solve the urgency issue of behavioral concerns. My personal discounted value of ice cream tomorrow might be superior to ice cream now, but it is based on the tacit assumption that the shop still exists tomorrow or any other time in the future. The exhibition invites people not only to play table tennis but also to discuss the question of tomorrow across language barriers and across tables and cultures. 
Sociology in Art
Sociologists study and teach a lot about social capital. James Coleman and Pierre Bourdieu each have coined social capital as a major foundation of societies. Therefore, the exhibition of the artist Rirkrit Tiravanija “happiness is not always fun” in the Martin Gropius Bau (Image below) is interesting beyond a justification art for art’s sake.
What does Tiravanija tell us about happiness and social capital we did not know before? The artist went to a Chicago based art school, hence, it is likely that he has been confronted with the concept of “social capital” by Chicago sociologist James Coleman. The Berlin exhibition of Tiravanija can be walked along and experienced through the lens of the creation of social capital as a form of art. Art raises awareness to the importance of social capital for the ways we live together and form communities. The Berlin exhibition, meeting place or play ground is worth multiple visits as the participatory experience changes each time. In each of the rooms we reflect on our cultural practices like sports, music, printing or cooking as forms to create community. Each time we take home a little bit of social capital as well. “Happiness is not always fun”, but for sure You’ll have many happy moments throughout the visit of the exhibition. The guided tour by curator Yasmil Raymond (2024-12-19) added yet another little bit of spice to the exhibits. For a few moments we felt like a strong link between Chicago and Berlin, just like those sociologists in Berlin who studied and continue to study James Colemen’s foundations of social theory.
Reconciliation
European history is a long history of atrocities committed against humanity. The Documentation Centre for Displacement, Expulsion, Reconciliation in Berlin (Image below) captures this history in a comprehensive manner. We are quickly overwhelmed by this weight of history and the implications this has for the understanding of the people on the globe. This relatively new learning centre has, beyond the memorable permanent and temporary exhibitions, a room of silence to recover from the hard work of remembrance, always in view of reconciliation.
The library allows personal search and research of migration documents and biographies. All centuries have their history of displacements, but the Nazi terror surpassed all prior records and forced millions into displacement or death. We are still working on this heritage and the enlightenment of how these atrocities could take place. Full consciousness of the terror and horror of the 30s and 40s is necessary to guard against the many attempts to falsify historical events or discard the sorrow of millions of people and their families.
Reconciliation remains a continuous challenge. A large part of diplomacy has to deal with reconciliation beyond concerns of daily affairs. It is not just a matter for head of states and days-off during a year. Stillness helps to deal with the challenge, especially if it is very difficult to find adequate words. 
Air Concept
Well yes, this is the latest fart in design and architecture. The Berlin International University of Applied Sciences composed an exhibition on “Air Architectures” which takes air seriously. The international group of 7th semester students took Air Architecture seriously and developed their ideas in the context of a curated exhibition. Nice semester project.
Air is a fundamental precondition for humans to (co-)exist. The biology of air (breathing) or the chemistry of air (fine particle matter) have been studied extensively. The physics of air flows in cities receive more attention as well in architecture. Interior design has yet a lot to contribute in the age of heat pumps and air conditioning.
Let’s think architecture from the perspective of air and air flow. Depending on our cultural background we might have very different associations with air. Indian or Chinese practices like yoga or Tai Chi teach us to take air more seriously than Western practices. Most architecture in cold countries of the northern hemisphere aim to keep air to the outside of buildings. Yet, the percentage of humidity of air is a serious concern of architecture as well. Air flow and quality then becomes a key issue of construction and architecture, somehow through the back door.
Maybe in approaching architecture we might think first of what is or has been the architect’s concept of air or aerodynamics. 100 years after the death of Gustave Eiffel and the Olympic Games in Paris, we still gain from thinking about air (not only air pollution) and its dynamics. Looking forward to the next generation of air architects.

Chinny Trait
In evolutionary biology there is still a discussion about the functional explanation of why humanoids developed a chin. A recent paper by Meyer-Rochow adds a new functional explanation for the evolution of the chin to the literature. Across cultures and sufficiently distant populations of humans, similar patterns of the use of the chin have been observed. In comparison to other species under the superfamily “Hominoidea”, our bites are only of minor strength and apes, Orang Utans have not developed a chin quite like us, homo sapiens. Origins of the chin as “weapon” in fighting and broader social selectivity remain hypotheses without sufficient proof of evidence.
In addition to the functional explanations of easier “mastication” or formation of words, chins might serve as an additional part of the body to hold items to the chest. This function, of holding tools or stuff could have been an advantage for our ancestors and became a favoured trait. During the pandemic our chins became a supporting or hindering reason in the struggle to wear masks for extended periods of time (see image below).
Nowadays, we ask ourselves about the social selectivity into becoming a violin player with this important function of the jaw and chin to hold the instrument. A rival hypothesis is, of course, that holding things with our mouth, like needles or screws, in sewing or handicrafts could eventually make the chin disappear. The bipedalism of hominids, freed our hands for other tasks and the evolution of a chin could similarly reinforce the efficient use of our hands.
Novel use cases for the chin, like holding your smartphone while typing on a keyboard or while opening doors, might enhance the chinny trait of hominids.
Over hundred of thousands of years the interaction of the bio->psycho->social (BPS) spheres of life may have interesting traits for us down (or up) the evolutionary line.

Kids Space
Political claims to reserve more space for kids in cities have a tough time. Kindergardens or child care in general are scarce and the lobby for kids is often limited in time and extent, since it is the parents that usually are the ones to advocate while their children are small. Jointly parents and children of young age experience the tough atmosphere to find, preserve or extend the space for kids.
The Gropius Bau in Berlin has opened up an exhibition space reserved to children 3+ as part of an art project “BauBau” designed by Kertin Brätsch 2024. A colorful room and installations as “loose parts” are the starting point to delve into a real/fantastic world were kids reign. There are a few so-called “playworkers”, who accompany the endeavours, if need be. At the end of the day the room was still in pretty good shape I would say assuming that “children set the tone and decide what happens in this place”. Safe and supportive environments for children are scarce and parents are always challenges in their attention to watch out for risks of all sorts in public city spaces.
Even if the “play space” is free of charge, it takes parents or kindergarden managers to reserve the space.
An early experience of a museum from the inside is likely to have lasting effects on children and the parents. They might have fond memories of a museum as an exciting space also for them. It constitutes a nice continuation of the outdoor “radical playground” project during summer 2024.
Korea relieved
On Saturday 14th of December 2024 the Parliament of Korea voted with 204 out of 300 votes, the required 2/3 majority of the parliament to dismiss the president. The declaration of martial law has been the most serious attack on democracy in Korea since its founding in 1987. It is the 3rd impeachment of a Korean president in this short time of democratic life cycle. After impeachment the constitutional court has to confirm the impeachment also with 6 out of 9 judges in favor of impeachment. In 2017 the judges confirmed the impeachment of a president due to corruption charges, but in 2004 another president was reinstated after illegal campaigning charges were retracted. Democratic procedures hinge on checks and balances in the constitutional set up of a state. Nominations, votes of confirmation of judges are important safeguards against illegal martial laws to restrict or even abandon democracy. Pressure from the street, the people at large, is another safety net of democracy. It should not be the last resort for democracy’s survival as it is likely to come at high costs of human lives. 
Health Tech
Health technology assessment (HTA) is an interesting scientific field. The new digital opportunities allow people to participate in medical and medication trials in their homes or even in bed. Their health data and the administration of medication is also encouraged and sometimes supported through digital devices. The pharma and health industries have many devices ready to go. The differences to the traditional forms of medical trials, however, is an issue as we want to compare the results from both kinds of trials. Participants of trials, might prefer or struggle with these novel kinds of study designs. In any case the results will be impacted in several forms (Study Link). In the best of all worlds for the researcher the effects will cancel out each other, but is rather unlikely. Some participants will reach more positive effects with the use of digital tools, whereas others are challenged and might even abandon during the trial. Monitoring during the study (for example through digital inhalors) is another advantage of such distributed trials. Rather than taking adherence to a trial medication for granted, digital tools allow a more precise monitoring of subgroups as well. Data and effort invested in the trial is preserved through the easier access to person’s information, assuming continuous readiness to stay on in the trial.
Our own smartphones are still underexploited in terms of health monitoring and use in research designs. The possibilities to link data to other external data sources shall further advance the research potentials in many interesting ways. Data protection and data security become even more important with the ever smarter phones and connected devices.
Health data
2025 will be a crucial year for health data across the EU. Germany introduced the electronic patient card, which can store basic information to then access data in the health insurance cloud for medical doctors, hospitals and other related health services. Potentially this is a great step ahead as some tests do not have to be repeated if they had been completed recently before already.
In pseudomised form, research may draw samples from such databases to enhance our science based understanding of disease. The evaluation of public health interventions becomes easier and medium and long term efficiency of measures can be assessed in many instances.
The Belgian research using health data has met to discuss the potential and limitations to link health data to other data sources to allow more complete and more complex analyses of health and disease processes. Another extensive data source sits on our smartphone. Collection of steps walked, sleep patterns or heart beats give valuable insights into a person’s own contribution and care about personal health. Although data are frequently incomplete, researchers are used to estimate missing data on the basis of existing or comparable person’s data. The basis for improving health for all are quite promising, data handling and linking them will be a challenge to the competence of all stakeholders and everyone involved in better health. It will be stressful before it becomes a routine. 
String Quartets
There is a plural form of Quartet. Philip Glass has composed a piece for 3 string quartets. Thanks to the Kronos Quartet performing and celebrating in Brussels, modern compositions are continuously added to the repertoire written for and performed by string quartets. Contrary to received wisdom the tradition of string quartets is still alive and kicking. At Bozar (Brussels) the marathon performance of 27 quartets, not all at once, but spread over a day and several locations, afforded a great free-of-charge opportunity to wipe off the dust from the sometimes rather introverted form of string quartets. Despite the high share of young musicians who performed well at the occasion, the afternoon focused more on new compositions. Concerning the audience, however, there is still an older age bias in listeners, more the standard Bozar clientele so far.
The afternoon reminded me on listening CDs entitled: “I don’t like classic music, but this one I do”. Many people came for art exhibitions at Bozar, but then (re-)discovered on the sideline the atmosphere of chamber music at this occasion. Closing the age and social gap in classical music is quite a challenge. It is surely more like a marathon than just a few sprints here and there. The new format at Bozar in cooperation with the Kronos Fifty for the Future Marathon will sooner or later find extended audiences beyond the happy few this time. I would recommend listening to string quartet music more often until the “Transcranial direct current stimulation (tDCS)” will be the new hype. 
Sociolegal Circularity
At times legal systems feel like going round in circles. Legal procedures move from one stage to the next and they may get referred back to the previous instance to resolve a particular issue or restart the procedure. This has good reasons with the aim of “doing justice”. Sociolegal circularity, however, begins before the, right at the beginning and negotiation of legislation on which all legal systems are based in democracies, that is. Hence, the legal definition of waste, recycling as part of the circular economy and society is rather crucial.
Circularity is a complex sociolegal issue as the example of PFAS in plastics demonstrate. In economic theory the existence of externalities invites profit seeking of the kind like: “the sea in large part is owned by us all and there is no price attached to the (ab)use of it. Dumb PFAS into the sea, because the costs of cleaning up will be shared by all of us”. In order to limit the extent of this economic logic, we have to rely on sociolegal processes. The precise definition of property rights and liabilities beyond the PFAS issue have to be well-defined. It is an intergenerational topic as well, not only in view of deferred payments.
Parliaments have to be rather competent to look through all the complex issues of producing and recycling of materials to make sound provisions in law including future generations. Going round in circles in parliament is yet another element of necessary condition of circularity in a rather broad sense.
The air we breathe and the water we drink have become part of this “economic externality”, which is a very internal, inside of our body kind of sociolegal affair. Who is responsible for the bad air we breathe and the contaminated water we drink? Air and water have for a long time become marketable products. The more your local water is polluted, the more we are forced to buy water. The more the air in inner cities is filled with fine dust particles, the more medical doctors, hospitals and rehabilitation facilities we need to construct.
For GDP calculations these are win-win-win situations, although they make us all worse off. Society and politics are in charge to define and redefine (yes, circles again) the legal basis with a lot of precision and scientific detail. Sociolegal circularity is key. You just have to turn it in the right direction.

Socioeconomic Circularity
Some sectors of the economy receive a lot of attention, for example sectors selling fancy cars. Other sectors, like the ones regrouped under the name of circular economy, receive much less attention and show up little in headlines. In fact, the circular economy is a great example of this. There are thousands of waste and rubbish collection, sorting and recycling centers, several hundreds of waste-to-energy plants, composting sites across the European Union. Of course, there is also a European Federation of the sector (FEAD). On the last FEAD conference in Brussels 2024 it became clear that Europe is finally waking up to the challenge of recycling costly raw materials.
The narrative concerning the sector needs to change further: what used to be subsumed as costly nuisance is in fact a potential profit center for companies and society at large. We do no longer want to import lots of raw materials from countries with dubious social and environmental records as part of our supply chains for raw materials. Time to act. This, however, is a rather complex socioeconomic challenge of circularity. The price mechanisms are not fully functional in most Member States, let alone across the EU. Additionally, the social practice to recycle varies greatly between countries. Distributional issues matter as well. It is rather obvious that dumping waste from one region/country in another one has huge implications (nuclear waste), but if one country values waste more than another one, due to innovative recycling techniques, the matter takes a marketable turn. Regulation should carefully distinguish categories of materials as we do for hazardous materials in production, consumption and for health and safety purposes of employees.
Metal, battery, cement, plastic and wood recycling pose challenges, but also opportunities to improve the European material import/export balance sheets. However, first in the circle of circularity is the use of materials. There we are clear that “less is better”. Less input of raw materials, most of which we import in the EU, reduces our dependence on other countries. This is the tricky social question of circularity. Mainstreaming of more conscious use and reuse of resources is a huge social issue, which we tend to relegate to a task for the education system. The awareness that supposed waste is also a valuable resource is spreading and the growth of the sector a business and employment opportunity for many. Circularity is the new sexy sector of the 21st century.
What have you recycled today? and myself? Well, scientific online publications. Now think of ChatGPT and the AI gold mines of 2024. There is lots of value in recycling.

Book Annotation
For most people book annotations are considered a nuisance. However, most pupils or students mark their so-called textbooks, which contain many images nowadays anyway. A good mindmap, summary of text, highlighting or critical comments may be part of their day-to-day working with a book. Some editors facilitate this using broad margins and more space between lines. Working through a text can take multiple forms and books have allowed over centuries different kinds of their usage.
There is yet another underexplored usage of books. On printed volumes annotations of previous readers may serve as a guide to a script of places, thoughts or material of particular importance. I have always found annotated copies of other readers interesting in their own right. Reading an annotated copy felt like reading another person’s mind, thought or learning process.
A modern view of books as a tool of communication might extend this perspective to study annotations of several readers on the same copy. Just like we comment today in word processing on texts from collaborators or students. Books are a means of communicating with other people or machines (AI) usually with the aim of spreading ideas, content, horror or pleasure.
Therefore, I am always happy to find annotated versions of a book, especially of prominent authors. It sometimes feels like reading a “partition”, a transcript of music which contains the comments or fingering of the reader or the performing musician. The BNF has a lot of such special copies in its archives, usually found in the donations of persons or prominent authors and their families to the archives. This can be put together to make an interesting exhibition of the process of thinking and writing and of special treasures – annotated books.

Book Value
What is the value of a book? For the author of a book each book s/he has written or sweated the value of the accomplishment is pretty high. From the publisher’s perspective a book is an investment and sometimes a very risky one. The book store makes choices and takes the risk to devote time and effort to select the bestselling books or the best one suited to the local or passing audiences. Next in line are librarians who either stock everything published in a specific language or country (legal deposit) or select from the offer according to perceived interests of their subscribers. On the way to their audience many mistakes may occur. Books miss their targets or librarians go wild in their efforts to guard or discard books. In any case, many books do not find their audience. Some sit on shelves for years and will never be touched by anybody. Other ones pass from one hand to the other rapidly with long waiting lists.
Even if many conservationists don’t like it, it is the use of books that honors books and authors. Pocket books play a specific role in this link of readers and writer. Use rather than conservation, is the prime role of these lighter versions of books. They also have to endure heavy weather, scratches and folding of persons focused on content rather than precious form.
Last but not least in line comes the market for recycled books. Re-use of read or unread books has increased over years and some readers are happy to discover a discarded book from a previous owner (public or private). The value of a book lies in most cases in the eye of the reader. This then makes it an object of competitive marketing and continuous auctioneering.
