The problem with pollution is, it is killing you softly from inside. It is almost impossible to escape air pollution as it is pervasive in cities, but also in the countryside where you do not expect it that much. This is the result of the study by Kuzma et al. (2024) published in “The Lancet Regional Health Europe”. Based on a data set of 8 million persons from Eastern Poland the effects of air pollution on myocardial infarction incidence was analysed. The use of the “European Union’s Earth Observation Programme” contributed data on air pollutants like PMs, BaP (benzo(a)pyrene), SO2 and NO2 concentrations. The multi-level data of 5 voivodeships, 101 counties, and 709 communities in Poland allows to differentiate the effects of damage to the heart tissue on cardiovascular disease. The other well-known factors are arterial hypertension, diabetes, obesity, chronic kidney disease, hyperlipidaemia, and smoking as most of us know already. The effects of BaP (benzo(a)pyrene) is shown for rural areas despite the lower observed traffic density in these areas. The killing occurs softly from within our bodies by just breathing in and out, and in and out continuously. The disease burden in these regions is observed with “recorded 63,154 hospitalizations and 5921 in-hospital deaths (9.4%) due to STEMI; and 76,543 hospitalizations and 4079 (5%) in-hospital deaths due to NSTEMI”. In short, the need to reduce air pollution further is an urgent demand that saves lives eventually.

Weight Stigma
The fashion industry has for a long time produced images of mostly women and men that did not correspond to the normal weight distribution of people. Skinny models were present across all media. The so-called social media of today amplify this trend further. The “Barbie hype” has reinforced the idea of low weight as a socially desirable norm. In scientific research the term coined for this phenomenon is “internalized weight stigma” (IWS). A study shows (Highes et al. 2024) it affects more women than men and more people who are described as socioeconomically disadvantaged adults. Pressure to lose weight originates from multiple sources and social media platforms have given rise to bullying. A major outcome of IWS is eating disorders as eating is often wrongly associated to be the only cause of higher weight. It is not. Many other factors contribute to the actual weight of a person. Even the overuse of the body mass index (BMI) as short hand version to define overweight or obesity is misleading for persons with strong muscles. Just fixing on one parameter of body shape or weight tends to reinforce weight stigma. “Keep walking” and a regular healthy diet, this avoids to internalize a weight stigma. Exercise is fun, the more you do it in a group, the easier it is to get going regularly. We ought to keep trying and eventually it will become a routine.

Screening Paradoxon
In the field of public health the screening paradoxon is a well-known feature of large scale programs to check for and contain the large increases in cancer among populations. A recent medical study underscores the necessity to curtail the screening paradox in Europe. The screening paradoxon is defined as “the underuse of screening by those with unhealthy lifestyles and high risks”. The opposite cases, “the overuse of screening by those with healthy lifestyles and low risks” only cause a problem for the costs of the health system as those unlikely of attaining a form of cancer make extensive use of screening. In terms of social inequality we have to be concerned about both ends of these distributions. The publicly available screening programs are skewed towards the higher educated with risk awareness as well as healthy life styles. More of them participate in screening. The other distribution of actual risks and detection of cancer is skewed towards the other end of the risk distribution. The 2 probability distributions overlap to an extent that is most likely co-determined by cultural factors like general attitudes towards prevention.
With the increase in cancer rates generally and due to demographic aging of societies, we shall need to target our resources devoted to health more precisely rather than spending too much on screening of people with very low risks. Increasing the duration between screenings might not impede detection rates of those with healthy lifestyles, but could allow to devote more resources to those people who are hard to reach by screening programs so far. Evaluations of such programs are necessary to judge the need for more targeted programs.(Image own representation inspired by Ola et al. 2024)

Photos Exhibit
Our usual expectation of an exhibition of photography is to look at photos at a wall. Sometimes there is more it. The Exhibition Space at the “Haus am Kleistpark” features Michael Schäfer who attempts to go a bit beyond these traditional forms. In the works of photo cubes on water surfaces “2021_57”, or a dice floating on the waves of oceans, the video representation of his photographs takes the assembled images beyond their flat 2D surface. However, the 2D representation is at the origin, then transformed into a 3D dice, which then is animated as a 4D format. Moving beyond the flat screen image takes photography into the 21st century.
His work “Les acteurs 1-26” from 2007 is shown at the entry hall of the exhibition. It shows pupils of a class at an elite school who deem themselves in leadership roles in the near future. Is it acting? Is it projection into a future role they are likely to take on. They represent stereotypes, of course, but some are pretty convincing in these roles already. Some others still seem to reflect on what they are doing there. Even acting these roles, they are aware of the meaning of social rank and class in society. Without having read the sociologist Bourdieu, all are aware of the fine, little elements of distinction as they have evolved over time. We could teach an interesting sociology class in this exhibition. 
Time Perception
There are many different angles from which to look at time. Of course, we all do it several times a day or during boring meetings. The study by Ma, Cameron and Wiener (2024) highlights the bi-directional link of perceived time and memorability. Visual stimuli alter our perception of time. Watching a video we all make the experience that the perceived length of the time spent watching varies according to content and maybe only the cutting technique applied to shorten the perceived length. Similarly it has been demonstrated that looking for longer at an image and grasp the meaning or implicit story we tend to remember the image for longer. In courts it is a usual procedure to question the memory capacity of persons and the sources of bias. The study by Ma et al. demonstrates the impact of the size of the scene, how cluttered it is and aspects of memorability in visual perception. Our memories are co-determined by these factors. The other direction of causality i.e. that memorability determines the time perception seems equally at work. This apparent undetermined element, so far, calls for additional care when analyzing recall from memory. Memory is not only selective in terms of content, it also is subject to the impact of all sorts of visual stimuli.
Time can be many things. For humans it is everything but exact. In science we measure time with ever more exactitude and try to standardize time on the moon now. In addition to exact time, humans have perceived time and subjective versions and even concepts of time. About time to take time more seriously. 
Hospital Bias
Asking people about differences between private and public hospitals, you are most likely getting answers that the private hospitals deliver superior patient outcomes. Whereas private hospitals seem to have a positive stigma attached to them, public hospitals commonly have a negative stigma. Scientific evaluations are helpful to set the record straight again. The study published in “The Lancet Regional Health” in 2024 shows that in the simple descriptive statistics on several patient outcome indicators, this is what the data showed between 2026 and 2019. However, a more precise statistical analysis reveals that there is also a selective admission to the private and public hospitals in England. Using so-called instrumental variables approaches that account for the selection process between admission to the 2 types of hospitals (private versus public) most of the differences between the hospital types disappear. The underlying mechanism is a sorting of different patients into the private or public hospitals. Put in easy words, for a routine intervention people tend to chose the private hospital, but the more rare and difficult operations were more likely admitted to public hospitals. The number of co-morbidities (heart disease) is also of importance as they might negatively affect patient outcomes. Jumping to conclusions and reinforcing stigma about public or private provision of services hinders progress and an equitable provision of services.
The analysis of a potential selection bias can reveal the “creaming” effect of private provision of (health) services. Just caring for the “easy” or routine cases and avoiding the more difficult and costly cases has economic advantages, but for society as a whole the costs overall remain the same. A good public service in health is a definite asset.

Digital Estonia
The progress of Estonia in going digital is quite advanced. The electronic identity card which allows data to be linked to health data and accounts or banking gives an impression of how far-reaching digitalization may go. Great steps have been taken to guide the population on the way to move towards the digital (only) world. Learning and coaching of a huge amount need to take place so that people do not abandon or get lost on the path towards “everything digital”. For the so-called digital natives, who have grown up with the sound of their smartphone at the bedside all the time, this move feels “natural”. Some experienced or silver workers got on track, if they were accompanied in suitable forms. The 65+ population might find it harder to adapt to the permanent use of digital devices for not only getting around in your city, but also to do your tax declaration, pay your dues and vote in elections.
Digitalization is not a goal in itself. It has advantages to reach communities in remote places or islands, but it might alienate older persons that have no other person around to assist them in the digital only world. An easy way to get some social science data to inform the debate is to refer to Eurostat and the surveys with information about the “overall life satisfaction” of people (EU-SILC). Checking for some major countries of the EU and neighbours of Estonia with less digitalization the differences are rather small. In terms of overall life satisfaction (16+ years old) Estonia has been catching up to the EU-average mainly between 2013 and 2021. Since then, stagnation at the EU-average is what the data tell. A quick testing of the hypothesis that the older persons (65+) might not see the past evolution as rosy is reflected in the EU-data as well. Good pensions seem to drive the “happiness” of older persons in the EU more than good digitalization. Eventually the two features of a society will have to go hand in hand to improve life satisfaction to higher levels.

Schachliteratur
Es gibt sie noch, die Personen, die Schachbücher lesen und kaufen. In vielen Sprachen existiert die Niche der heimlichen Strategen. „Teaching old dogs new tricks“ oder ist es eher „teaching young dogs old tricks“. Das ist eine empirische Frage. Nicht nur Zeitungen für sogenannte BildungsbürgerInnen haben noch kleine Spalten zumeist mit Schachproblemen. Manchmal findet sich Schachspielen sogar als Schulfach. Lesestoff zum Schachspiel findet sich reichlich. Schach in der Literatur ist jedoch verschieden von der Schachliteratur, die sich mit Strategien und Tempi befasst.
Das Lesen von Schachliteratur mit Meisterpartien hervorragender Spielenden ist vergleichbar dem Lesen einer Partitur einer Symphonie oder Oper. Das Kino spielt sich dabei überwiegend im Kopf ab. Gelegentliche unvermittelte Gesten oder Ah-laute sollten den Spielenden ihrer Verzückung wegen entschuldigt werden. Vielleicht sollten die Schulen diese Kulturtechniken mehr vermitteln. Macron‘s Vorschlag Theaterspielen mehr in den Schulen zu vermitteln erscheint in diesem Vergleich als ein Entgegenkommen an die „Generation der sich ständig selbst inszenierenden“. Mehr Spielen ist aber schon mal ein wegweisender Vorschlag.

Causal Benefit Model
In the field of medicine we move more and more towards precision medicine. Previously, the term of personalized medicine was used which suggested to a certain degree that a personalization might be feasible. The budget constraints have forced us to change the term to avoid unrealistic, untenable promises. In the field of cardiology scientific advances advocate to shift from a risk-based model of treatment to a causal benefit model. (Kohli-Lynch et al. 2024 Link). Long-term benefits of a treatment are more promising, if the treatment addresses the causal mechanisms at work. It is wide spread practice to deal with general risk profiles as guidelines as the precision medicine based on a causal benefit model is far more laborious since to search the causal mechanism at work requires additional testing of hypotheses. This becomes immediately clear if genetic causes enter into consideration. Nevertheless, medical research advances more and more in this direction. Genetic testing has been shown to be useful in analyzing and treating issues like sudden cardiac arrest (in survivors). We are somehow aware that genetics may play a role here, but we shall need a lot of additional studies to make the causal benefit model a feasible option for widespread applications. Targeting research in this field will offer new avenues for precision medicine in the 2020s.

Series Evaluation
The monitoring of TV series is a serious science. The evaluation of so-called binch viewing has redrawn attention to the field of media studies again. We observe a bit across Europe, following the US experience, the change of TV productions into series that may run over several years. The successful format of a TV series draws advertising to the relatively constant audience. Most series have a particular age group as their target group. Viewing behavior determines time slots allocated. Each group has its own prime time. The publisher of books had their successes with similar series of for example children’s picture books or cartoons. Asterix, Martine and similar book series have basically applied the same “serial” mechanism before. Popular success creates its own dynamics. Therefore the evaluation of such serial productions should stay on our research agenda of the social sciences as well.
In a radio discussion “France Culture” has juxtaposed the 2 currents of series evaluation in a concise way. One current of assessment holds the view that rather than high versus low culture, the debate should take popular culture seriously. It augments the set of experiences as the characters in a TV series live through a kind of “experimental setting” each time anew. The variety of experiences is catching popular attention as they are beyond the scope of the spectator’s usual life settings and thereby a learning opportunity. This highlights the value of the content in the evaluation. This requires a thorough scrutiny of that content to evaluate an emancipatory value of viewing it (Sandra Lauglier, 2023).
An opposing view is defended by Bertrand Cochard (2024) with reference to the conflict about one’ use of free time available to us and how we spend it. His criticism takes issue with the amount of time “lost” by viewers of series. Time is not spent twice. The loss of time alone or side by side rather than spending it with other persons or physically active constitutes a major risk to the social fabric of society.The jury is still out on the issue. We likely see the start of a series of entries on this topic as well.
