Biological processes work hard during our sleep. Our immune system in particular benefits a great deal from undisturbed sleep. This is the simplest summary of the study by Kabrita et al. (2024).
We can study the temporal expression pattern of major histocompatibility complex MHC class I for example in mice. 2 groups of sleep-restricted versus normal mice reveal the biological impact of sleep restriction. In comparison to the control group sleep restriction in mice produced a bimodal pattern of Splenocytes with higher protein levels during the resting period. Such an increased protein expression during resting periods indicates a “preparedness for a potential infection”. Sleep recovery, even if short compared to the longer sleep restriction, allows to return to the baseline of protein levels. The good message is that at least mice seem to recover rather quickly from sleep deprivation with their immune response system.
The biology of repeated phases of longer sleep deprivation could inform us on the implications of sleep deprivation on aging processes. The biological responses in single event sleep deprivation seem to show a fast recovery pattern. Probably it is worth studying the same recovery process of groups of young versus aged mice.
Anecdotal evidence from myself indicates that recovery after sleep deprivation in older humans is no longer as fast as at younger ages. Behavioural responses might be less sleep deprivation (less fun) or longer recovery periods (stay in bed longer). The behavioural response of humans appears to be an obvious one. Instead of either or, we tend to go for both at the same time.

Korallenriff
Kinder verstehen direkt, dass es sich lohnt, Korallenriffe zu erhalten. Plastikmüll in den Meeren gefährdet die Korallenriffe und die bunte Vielfalt an Fischen, die darin leben. Ein kleines Theaterstück dazu von Kathrin Brunner begeistert Kinder, weil es sie erleben lässt, wie einfach Lösungen aussehen können. Den großen Leuten zeigen, wie traurig die Welt aussieht ohne die farbenfrohe Pracht der bunten Fische, wird sie schon zu Veränderungen bringen. Das Theaterstück und Buch dazu wurde am 16.3.2024 im FEZ in Berlin aufgeführt. Das Figurenspiel mit überleitendem Refrain, das vom Publikum gleichsam der Promenade in den „Bildern einer Ausstellung“ (Mussorgsky) mitgesungen haben, bildete jeweils eine gelungene emotionale Überleitung und Aufmerksamkeitspause. Wir wünschen uns noch viele kleine und große Besuchende für diese Aufführungen. Die Kinder werden es uns schon lehren, den blauen Planeten noch zu retten.
Family Music Days
Kids are queens, kings and princesses as well as princes at the family music days in Berlin at the FEZ. Kids can enjoy the full spectrum of musical experiences from just listening to playing themselves, if they feel like it or dare to risk a sound. Just making noise is okay, too. Building your very own version of a musical instrument is a great learning experience for the young. To make music it doesn’t always have to be an expensive instrument. Your own imagination assisted by persons with patience and passion creates marvelous sound experiences. Initiating kids to the endless worlds of sound is having lasting effects on them. Great to see a concert hall full of young enthusiasts. Learning is so much fun, if taught in accessible and inclusive ways. Professional instructors joined by many volunteers make the world go round for kids. Wish you we here. Let’s spread the message.
Need of War
It seems like a horrific idea to talk about the need of war. We might have deemed it outdated to read about the terrible love of war or about the strategy of war. However, the time of war is back in Europe and Eastern Europe feels the real threat and Ukraine the bombs hailing from Russia. Why does Putin love war? The love of war is largely driven by domestic issues. Staying in power for unliked authoritarian leaders is easiest if they indulge in external conflicts. Dictators love war because it makes it easier for them to sustain leadership through brutal force within the country due to a proclaimed external threat or even outright engagement in war. Democratically elected leaders know that they will leave office eventually in a peaceful way (exceptions like Trump are rare). Dictators use any force or terror necessary to stay in power. The love of war is part of this.
Hence, the need of war goes without questioning, if a country in decline or at risk of decline tries to uphold an inefficient, belligerent regime. Beyond rational reasons, such regimes will abuse ideation about national pride, the national interest and anything pertaining to some supposed myths of nationhood to justify its need of war. The dictators have all failed eventually as resistance against this need of useless war is found out by enemies either within or externally. But thousands or millions of victims will suffer. The pressure against the need of war has to rise internally from opposition as well as from alliances of democracies that do not need war to motivate their people to achieve the best they are able to deliver.
Therefore, the defence of democratic rule is, at the same time, a fight against the need of war by some doomed regimes. After winning the war comes the difficult task of winning peace. This means to create a state of affairs and a state of mind that can do without the need of war. If the external threat diminishes the internal threats might rise and have to be contained as well. Lots of challenges, even for mature democracies. (Image: Berlin 2022-10)
AI and S/he
There was hope that artificial intelligence (AI) would be a better version of us. Well, so far that seems to have failed. Let us take gender bias as a pervasive feature even in modern societies, let alone the societies in medieval or industrial age. AI tends to uphold gender biases and might even reinforce them. Why? A recent paper by Kotek, Dockum, Sun (2023) explains the sources for this bias in straightforward terms. AI is based on Large Language Models. These LLMs are trained using big detailed data sets. Through the training on true observed data like detailed data on occupation by gender as observed in the U.S. in 2023, the models tend to have a status quo bias.
This means they abstract from a dynamic evolution of occupations and the potential evolution of gender stereotypes over years. Even deriving growing or decreasing trends of gender dominance in a specific occupation the models have little ground for reasonable or adequate assessment of these trends. Just like thousands of social scientists before them. Projections into the future or assuming a legal obligation of equal representation of gender might still not be in line with human perception of such trends.
Representing women in equal shares among soldiers, 50% of men as secretaries in offices appears rather utopian in 2024, but any share in-between is probably arbitrary and differs widely between countries. Even bigger data sets may account for this in some future day. For the time being these models based on “true” data sets will have a bias towards the status quo, however unsatisfactory this might be.
Now let us just develop on this research finding. Gender bias is only one source of bias among many other forms of bias or discriminatory practices. Ethnicity, age or various abilities complicate the underlying “ground truth” (term used in paper) represented in occupation data sets. The authors identify 4 major shortcoming concerning gender bias in AI based on LLMs: (1) The pronouns s/he were picked even more often than in Bureau of Labor Statistics occupational gender representations; (2) female stereotypes were more amplified than male ones; (3) ambiguity of gender attribution was not flagged as an issue; (4) when found out to be inaccurate LLMs returned “authoritative” responses, which were “often inaccurate”.
These findings have the merit to provide a testing framework for gender bias of AI. Many other biases or potential biases have to be investigated in a similarly rigorous fashion before AI will give us an authoritarian answer, no I am free of any bias in responding to your request. Full stop. 
Magritte Symbol
“People always search for symbols in my works. There are none.” For those familiar with the work of Magritte, they know that he means precisely the opposite of what he is stating there. He applies well-known symbols like the white pigeon representing peace in his paintings to represent and make us think about peace. The image becomes surreal in the sense that we go beyond the real world of violence and war to lift our attention to the other surreal version of the world as it currently appears to us.
In times of war, it is more difficult to image a peaceful world and yet, this is the time we need to believe in the possibility of peace beyond the reality of aggression. In 1966 Magritte has painted “L’oiseau de ciel”, the year the peace movements became more than a surreal dream across the world. It remains a challenge to think beyond the cold war at the time and the hot war initiated by Russia in Ukraine. Surrealism helps us to think beyond the real state of affairs.
In Magritte’s own biography the “dove of peace” occurs towards the end of his own life. Whereas at the onset of his career as painter he dealt with depression and suicide in his family, towards the end of his career he moves beyond the autobiographical topics. Globally valid symbols gain the upper hand. The life course seems to have come full circle.
Symbol
What is it that makes an object a symbol? Probably, it is the widely shared perception of the meaning of a symbol that turns an object into a symbol. The etymology of the word symbol refers back to the Greek word σύμβολον. The earliest philosophical refer back to the Greek philosopher Aristoteles who deals with symbols when he writes about interpretations. Written words have become powerful symbols in the ancient world. We still have them all around us today. The interpretations of the words as symbols, however, may change considerably over time. Some symbols keep their designation and significance over centuries. Maps are well known to contain lots of symbols for roads, railways, tunnels or height. We learn about these symbols and interpret them in a specific societal context. Science is making ample use of symbols, e.g. chemistry. Different cultures define and apply their own symbols. Colonialism has been a form to impose symbols upon other societies. Throughout history symbols of power have changed as well. Each of those topics is an interesting field of application in itself. Young generations create their own symbols to establish a specific cultural identity or subculture. Urban spaces have been invaded by graffiti that tend to spread symbols as messages or symbols for their own sake.
Sociology has taken up the challenge to identify “status symbols” of groups of society. Possession of gold and silver have long ago been symbols of being rich. Maybe, even today such easily visible symbols play a role in how a person’s role is perceived in societies. Not only for priests etc. dresses have been applied as a symbol. Modern fashion is full of symbols as well. Interpretation of the meaning or even no meaning is an act of becoming conscious of the world around you. From the seriousness of symbols, we have come to the playing around with symbols as expressions of ourselves.
No matter whether we use the word, like water, we all know the chemical symbol H20. An image or art work using the symbol in whatever form will be decoded by us accordingly. However, the meaning we attach to water depends on the environment as well as specific context we (or the artists) are using it in. Cross-cultural competences consist in the awareness that symbols grow out of contexts and need to be interpreted accordingly. It needs a lot of openness, willingness to learn about differences and careful consideration in our everyday world to handle symbols. Doing culture is doing symbols.(Image of art work by Anderegg, Andi taken in 2016)
Biographies
The biographies of painters, composers or artists in general can be reconstructed by use of their major works. The biography of René Magritte by Eric Rinckhout (2017) has chosen this way of a retrospective in images and explanatory texts. The biography is built around 50 major images starting with the first one by Magritte at the age of 28. “Les réveries du promeneur” (see below) deal with the confrontation of Magritte with death, suicide and the difficulty to find rational answers to all those questions of why this happens and what becomes of people who experience such a tragedy.
His own childhood was affected by such an event concerning his own mother who suffered from depression. Coping with the evolution of psychic illness over years and the absence of a supportive father have posed a steep challenge for the young person. Creation of art became a coping strategy as well as a relief for those who manage to eventually cross the bridge into their own life leaving behind the bad experiences. J.J. Rousseau was an influence on Magritte as well.
Finding your own destiny and your own style is a process. This process evolves over years. The chronological sequence of 50 images allows to follow the path taken. Thereby, it becomes possible to open up the personal learning and working trajectory of the artist. In retrospective perspective it seems often logical that one style or period of painting follows on from another one. However, in the forward living of the creative life many choices are heavily contingent on other circumstances. Influences of friends, exhibitions, reading, cinema, private or financial situations may determine the creative choices simultaneously or one at a time.
The chronological path of images writes a biography of a special kind. It allows to think in sequences just like in a sequence analysis as sociological methodology. Description, reconstruction, analysis, causality remain a challenge in our attempts to learn and understand more about biographies or the construction and reconstruction of life courses. 
Corruption Watch
There is a persistent need to watch carefully whether corruption is involved in political as well as economic deals. Transparency Watch is doing a great job in reporting on corruption cases. In democracy we can talk openly about corruption but in authoritarian regimes it is life-threatening for yourself to talk and report on corruption. The case in Europe around the network of Eva Kaili continues to make headlines due to the ruthless abuse of rules the European Parliament. (Link to Le Soir, image below, 2024) The close monitoring of activities and lobbying of powerful industrial interests targeted on parliamentary candidates and officials will continue to be essential for the survival of democracy. The organization „Abgeordnetenwatch.de“ is doing just this. Investigative journalism needs to complement the work of NGOs in this field. Thanks to these efforts it has become much harder to cover up corruption. Only if the risk to be found out is a credible threat corruption can be contained. Let us watch out carefully and probably with the assistance of AI to uncover early any attempts of corruption.
Schachnovelle
Die Schachnovelle von Stefan Zweig gehört seit langem zu den Klassikern der deutschsprachigen Literatur. Zuletzt hat Jean-Philippe Toussaint in seinem autobiografischen Roman « L’échiquier » dieses Werk nochmals gewürdigt. Die psychische Belastung der fortgeschritten Schachspielenden macht spannende Lektüre. Bei Stefan Zweig ermöglicht das kognitive Training mittels Schachspielen die Bewahrung vor dem drohenden Wahnsinn durch Isolationsfolter. Gedankliche Fokussierung auf das Schachspiel und Spielen gegen sich selbst im Gedankenexperiment werden Rettung und Flucht in virtuelle Welten. Dennoch hinterlässt die Intensität der Erfahrung Spuren. Absorption ins Game, heute als Gaming meist verharmlost, lässt sich in vielen anderen Lebenssituationen wiederfinden. Es kann zur Sucht werden und Personen komplett absorbieren. Alleine Rauskommen oder vom Trip runter kommen ist schwer. Glück haben diejenigen, die professionelle Hilfe suchen und bekommen können.
