Zadkine Van Gogh

Ossip Zadkine has been a sculptor in cubists’ art tradition. He created famous sculptures of Vincent van Gogh after the death of the renowned painter and his friend. The Zadkine museum in Paris allows to get a great impression of these artworks. These sculptures reveal an interesting life course perspective on both artists sensitivity and transformation of their impressions of others or emotions more generally. The first study depicted below by Ossip Zadkine of van Gogh shows how he carefully studied the traits of van Gogh and his personality in order to better understand the evolution and death of the fellow artist. The emotional and broader psychological aspects of a character captured both artists. Doing justice to these inner feelings and society’s judgments about art and artists at their time of creation had strong impacts on both artists.

Air pollution dementia

A comprehensive review and update of evidence that indicates a link between air pollution and dementia has been published in “The Lancet” open access on 2025-7-25. Besides a genetic predisposition the environmental impact of our worsening air quality caused by fine dust particles and PM 2,5 and nitrogen dioxide NO2 has been found in several studies. This updated meta study should be an additional warning to take efforts to clean up our air more seriously. The diesel engines amongst other sources of air pollution have contributed a great deal to this evolution. Inner city inhabitants are at greater risks to suffer the consequences as they are more exposed to these pollutants and for longer durations. Clean air is a matter of brain health in advanced age and biodiversity as well.

Genetic diversity

Part of genetic diversity is the apparent fact that some partnerships have only girls or only women as descendants. This is the message of a study published in Science Advances by Wang et al. on 2025-7-18. The commonly assumed binomial distribution where each event has an equal chance of occurrence at each new point in time does not necessarily hold for this particular events. Therefore, the search for a genetic explanation has been going on for some years. Therefore, there might be a potential for an epigenetic explanation as well, as environmental conditions might co-determine the expression of genes in both parents. The research will surely continue and the sex and gender diversity offers still a lot of surprises. A sociologist’s perspective would tend to focus on later gender attributes and choices rather than sex at birth. The bio-psycho-social research agenda remains wide open.

Sedentary Lifestyle

There seems to exist a correlation between a more sedentary lifestyle and the level of industrialization. Industrialized countries have attempted to beat the running of time by faster modes of transport. From horses to cars, trains and airplanes. As a corollary of wanting to go faster the number steps walking has decreased compared to countries with less private or public means of transportation. The the time you spend sitting in transport the less we tend to walk or cycle. Obesity has become a dangerous consequence for large parts of those sedentary individuals and sedentary societies. The contribution by Paul Klotz in “Le Monde” from 2025-7-26 (p.24) highlights the bio-psycho-socio co-determination of the sedentary lifestyle. Societal developments to build entire cities more suited to car and train traffic has made walking the city a stressful task. Rebuilding our cities with a focus for a society on the move again is a challenge for more than one generation.

Electric Fun

The 60s, 70s and 80s have been fantastic precursors of the “All electric society” because of the electric music 🎶 industry that became a mass phenomenon. First of all the electric guitar allowed a wave of new music to take hold of a whole generation and probably keeps its adepts until today. E-pianos, keyboards, drum machines and synthesizers made music playing more accessible as well. You just need to plug in your instrument and you were able to produce an overwhelming sound. Other electric pleasures might include water pumps for water heaters and sprinklers. Electronic games and gadgets soon took over in children’s rooms. Of course, calculators as precursors of mobile phones and computers were another step in the progress towards the “All electric society”. Electronics are about to govern large parts of our lives and society. We better take a serious look at what we gain and what we might lose.

Just walk

The benefits of walking for several health outcomes is well known. The evidence is in favor of 7000 steps per day as a reasonable baseline. Some outcomes improve further if we walk even more steps, but not all. Probably, the effects of being accompanied while walking will enhance outcomes as well. Every summer the step threshold may be pushed a little bit further. Goal setting can help along to overcome eventual barriers to leave the home later in the evening. Nature rewards us with changing daylight and seasonal changes. We just have to get started to reap those health benefits.

Work time reduction

One of the major elements of social progress in the 20th century consisted in the reduction of work time. Reductions from 48 hours per week in the first half of the century were largely reduced to 40 hours per week or less in some industries with strong trade union representation. State regulations also pushed in this direction with positive implications for physical and mental health as well as wellbeing. Advances in longevity of employees may be attributable to this social progress agenda of the 20th century. In the 21st century we witness a new thrust of enterprises and employees striving to implement a 4 day work schedule by at the same time organizing a further reduction of work hours. The scientific evidence which is based on pre- and post trial assessments of workers satisfaction shows rather positive results (Fan, Schor, Kelly, Gu 2025). More studies are due to accompany this potential of further health and wellbeing effects of reduced work time and the reorganization of work time in enterprises.

Climate Awareness

The Musée d’Orsay has prepared a wonderful walk through its permanent exhibition of late 19th and early 20th century installations to reflect upon climate and climate change. Raising awareness about the treasures lost and those we are about to lose in the next few years. Impressionist painters have depicted landscapes, cities and monuments covered in snow, which the next generations will no longer be able to enjoy the same way. The roofs of Paris covered with snow has become a feature of a distant past. Additionally, the impression of the massive steam trains crossing metal bridges appear as the daunting future of technical progress. Mixed feelings of fascination and risk associated with those machines were captured by those painters’ eyes. Nowadays we are aware of the consequences of this technical progress for our planet. The walk through museum with a focus on climate related paintings is eye opening indeed. (Image: Extract of Éduard Veuillard, Le jardin des Tuileries, Musée d’Orsay, Paris)

Electrifying Jobs

The transition to the “all electric society” necessitates to prepare the labor force for the upcoming challenge. The knowledge about electricity and electric appliances constitutes the basics of the knowledge base of the future. This goes far beyond the basics of physics and electrical engineering. There many processes like sharing of electric infrastructure in households, cities, in and beyond countries that have to be delt with. Investment calculations and legal issues to address the different risks involved are another area to cover in the process to prepare society for the “all electric society”.
However, the skills of professions with more direct links to the fossil fuel based technologies have a role in the phasing out of the heavy reliance on fossil fuels. Reverse engineering of such engines and heating will need people still knowledgeable of the past, when younger generations set their focus primarily on professions with links to electricity. Even using a solar powered heat pump in a home requires pipes to the existing network of radiators, for example. This will most likely be a gradual shift of the job structure and occupational requirements over at least a decade, but the shift has started already. Some might argue we need a well functioning “transitional labour market”, labour market policies and social security system for this to happen smoothly.

Less but better

There are many examples where a new mantra for the 21st century emerges from recent scientific evidence: “Less, but better” (Lbb). In studies of nutrition and human dietary requirements, the importance to eat less has been demonstrated on a regular basis. And this is even more important than to do more exercise if weight loss is the target or the attempt to explain obesity across the globe (McGrosky et al. 2025). The case for eating less is strong. Eating better refers to the need to avoid unhealthy, toxic or cancerous food or the way to prepare food. “Less but better” could become the new mantra or “categorical imperative” if you like it more philosophical in tone. We, the people gain, and the planet will gain as well. It is an easy win-win case, albeit with some behavioral implications.
