Cardiac arrest detection

The number 1 cause of death is cardiac arrest in the modern world. Hence, the interest in the detection of cardiac arrest could save many lives. For assistance to arrive and intervene in time an alert needs to be issued as soon as possible. With early detection by nearby persons and skilled intervention the survival chances are about 50% of cases. The “silent” at home cardiac arrest is an important health and survival issue. The availability of wrist bands and watches which can issue alerts in combination with smartphones has risen considerably in recent years. Therefore, the improvement of reliable algorithms which interpret these data can realistically save lives as the delays can potentially be shortened for professional helpers to arrive. The study by Edgar et al. (2026) tested such a device and were able to show the very low number of false alarms issued by this device (about 1 out of 40). Extrapolated to millions of cases the challenge to a health care system is steep. However, we have to deal with such socio-economic issues of digital devices in medicine in the coming years more often.

Fuel fertilizer food

The state of world affairs can be summarized in relation to these 3 factors. Fuel, fertilizer and food are the subjects of the hotly debated or even contested resources. From a United Nations perspective the progress in human and economic development hinges on these 3 key issues. The logical order of the Fuel, fertilizer food triad starts with the costs of fuels or energy more generally and leads to the production and distribution of fertilizer across energythe world. This chain of supply determines the quantity of food available to feed the world. Russia‘s war on Ukraine territory has made this logical sequence obvious again. Millions of people were suffering due to the fuel, fertilizer and food shortages due to excessive price hikes. If we add speculatove rent seeking to this we have a scenario where the global South is suffering due to political contests and wars in the North including the Middle East. The current governance structure of the United Nations is largely unable to address this triad adequately. Fair processes of decision-making, control and implementation are crucial in this respect to ensure that all regions independent of economic spending power at sufficiently represented at the international negotiations about fundamental resources. Minimum levels of provision are necessary, even if not sufficient, conditions for our humanitarian responsibilities.  

Inclusive design

In aging societies inclusive design is not an option but a must have. This is neither a short term fix nor a renovation without costs. Adapting a home to a wheelchair use is an expert job as you have to think about issues you have not experienced yourself before in most cases. Door thresholds and openings, better have sliding doors as much as possible, have to be considered early. Bathroom adaptation in size and height, toilet space and lighting switches all should be planned ahead. There exists a DIN Norm 18040 which specifies measures precisely. In the age of AI-vibe coding some home appliances could be programmed to follow a person’s voice commands as well. For the time being in 2026-7 this is a nice to have option. but early installations of “intelligent digital devices” beyond a washing machine or microwave can get you quite far in the near future. Inclusive design could open doors and switch on lights simply by talking to your smartphone.

Water pleasures

Maybe some of us associate water pleasures with the splendid fountains in the castle of Versailles (France). Our daily concerns, however, are much more about making cities more resilient and able to cope with water scarcity. According to a study by Krueger et al. (2025) the user perspective and behavioral challenges that go along with saving water by end users has been neglected for years. Water management in cities is part of the infrastructure package that has to be managed efficiently. Aging water distribution infrastructure is just as much a problem on the supply side of water as consumption has its (increasing) price on the users side. Rainwater capture, re-use and recycling are promising alternatives to simply providing more water. Pollution is, of course, another hazard that needs our attention. In the meantime we may think of water pleasures for all including the animal world.

Berlin moves it

Yes, we like to move it. Investment in infrastructure follows a long-term economic rationale. In urban areas space is a scarce and, therefore, an expensive resource. In order to use the current space for mobility more efficiently, the use of a longer tram or train is an effective way to increase capacities. Rather than to increase the frequency, which is no longer possible without safety risks, a longer vehicle allows to bring more, and more diverse, passengers on board (kinderwagen and wheelchairs included).
It is a long-term objective to make urban areas liveable for all ages. Tramways which allow a low or, better, no barrier to entry is a necessary condition in this respect. The new “Urbanliner” in Berlin (image below) offers such essentials of access and urban mobility. A single tram is 50m long with 88 seats and 215 standing persons in larger corridors. 300 tram passengers can be compared to about 12 average length cars with at best 15-20 passengers.
A consensus of “how best to move it” in cities pays off in the long-term. Planning has to start about a decade before delivery and needs to survive political cycles going back and forth.

Learning locations

We tend to associate schools as the primary learning locations. However, there is a multitude of additional locations that offer excellent learning locations like museums, libraries, churches, enterprises or various associations. Some of these learning locations have better equipped learning facilities and environments than many schools. It is about time to reckon with this and advocate stronger links between the often disconnected worlds of learning. Teacher training focuses on schools, curricula and teaching methods, but the systematic combination of all these „external“ learning locations with the full-time schooling world could stimulate so much more learning. Maybe, even the social selectivity of education could be reduced through the motivation and different entry points into learning by a diversity of learning locations. Lifewide and lifelong learning are likely to be motivated at an early age. (Image: Stabi West-Berlin 2026-7)

Water in Parks

In 2026-7 and a 3rd hear wave approaching, the real luxury consists in water in inner cities. As a source of refreshment and cooling when temperatures rise, water provides a natural source to cool down nearby people, buildings as well as any trees. The wisdom of a hundred years ago appears again as a major solution as global warming progresses. Evaporation of water is cooling. Some simple facts deserve to be repeated over and over again as urban planning seems to have forgotten such simple physics. We have think about a lot of green and blue spots again in our cities to achieve the much needed cooling effects. (Image: Viktoria-Luise Platz, Berlin 2026-7)

All the lonely people

This line of a song by “The Beatles” dates back to 1966. “Ah, look at all the lonely people” is a kind of puzzled outcry to reckon with the loneliness even in busy and charitable places. 60 years later in 2026 we have whole ministries in some countries to deal with loneliness. It is not a niche problem. Tackling the problem needs to go beyond raising awareness. Loneliness occurs at all stages of the life course: children, adolescents, young adult, migrants, employees, single parents, care giving people, even within couples, seniors and very old persons. It is not restricted to urban or rural areas, but changes from one to another phase in a person’s life course carry the risk to encounter loneliness. It may well be only a temporary phase before new relationships can be established or previous contacts revived. There is a role to reach out to people who might be lonely for all of us. Public policies should be scrutinised on all levels whether they manage to break barriers or raise new ones for persons to feel lonely. In Berlin, the local level in each district is taking measures to facilitate informal meeting points open to all ages and walks of life. The “Wüstenrot foundation” sponsors many initiatives where public policies are short of funds. Projects enhance networks of people and organisations eager to assist “all these lonely people”, wherever they all come from.  (Image: Conference on loneliness at Berlin city hall Schöneberg 2026)

The next big challenge in medicine and public health seems to be the multiple long-term conditions. Many people do not suffer from just one medical condition, but several ones at the same time. Diabetes is one such condition which frequently comes along in combination with other conditions. The definition of Multiple long-term conditions comprises 2 and more conditions like cardiovascular, metabolic, respiratory or cancer, to name just a few of the more common ones. Our health and care systems are little prepared for adequate treatments as this involves a coordinated intervention and poly-pharmaceutical therapy. Changes in a single condition have repercussions in the condition and treatment. This makes adequate treatment a resourceful process with limited knowledge about the multiple interactions and intervening parameters. Add, for example, depression to any of the above mentioned conditions and the behavioral assumptions of correctly taking prescribed medication becomes a major issue for patients. The challenge for aging societies and societies with more people suffering from early onset of obesity and diabetes increases in the coming decades. There are several teams that address these challenges in research which gives hope to all those suffering already from Multiple long-term conditions.

Climateflation

Central banks have started to deal with the impact of climate change or inflation, short “climateflation”. New and additional inflationary pressures originate in climate change and global warming and they necessitate a closer scrutiny. Heat waves, like 2026-6 in Europe, or earlier ones have created an upward pressure on prices. Loss of agricultural production can be severe due to weather extremes which occur more often and with greater intensity. Such extended hot and dry climates reduce the production of crops and spikes in prices that only reluctantly return to average levels shall cause price inflation (climateflation). These are the short term impacts.
The medium run impacts alter price relations and valuations of in sectors like housing and infrastructure. Badly isolated stocks of housing, schools or hospitals depreciate valuations and the heavy investments needed for isolation of roofs, walls and widows as well as heat pumps to produce cooling shall be in very high demand, which makes price increases more likely across the construction sector. As we expect new devices to be “AI-intelligent”, “mem-flation” will be pushed up as well. These factors can give a push to some economies which are producers of the products in high demand and able to expand production rapidly as well. Just importing higher numbers of air-conditioning systems from other countries shall worsen trade balances.
The major challenge, however, remains our inaction to stop global warming to avoid additional economic and human losses related to climateflation.
