For Rafael Lozano-Hemmer, the relationship between art and technology in the 21st century is nothing unusual. His works, which border on theatrical and performance art and make use of projections, sensors and communication networks, deal with this dichotomy and appeal directly to the observer in search of the answer to the question: How much does technology tell us about ourselves?

As the world population closes in on 8 billion, the old "buy, use, throw away" paradigm of the linear economy no longer makes any sense and is driving us towards an uncertain future. Realisation of this has led to the emergence of eco-design, a production perspective that consists of integrating environmental protection criteria into every phase: from conception to development, from transport to recycling.

The outbreak of the COVID-19 pandemic led to record approval time for COVID-19 vaccines: less than a year. Since that year of lockdown, the World Health Organisation has approved several vaccines for diseases that, like COVID-19, have affected large numbers of people around the world, e.g. Ebola, polio, malaria, papillomavirus, and is in the process of approving a vaccine against monkeypox (Mpox). In view of its importance let's find out a little more about the history of this medical breakthrough that has saved millions of lives since it was discovered and will continue to do so in the future.

Climate change is a reality and threatens the future of the Earth. This can cause psychological impacts on some people, a phenomenon which is known as eco-anxiety. Below, we review what it is, what causes it, what its symptoms are and what we can do to avoid it while taking care of the planet.

The availability, access and consumption of nutritionally adequate food are the three pillars on which the concept of food security is based. Climate change, water scarcity and soil depletion are some of the threats that threaten it globally, which have now been joined by the socioeconomic effects of the COVID-19 pandemic.

The Food and Agriculture Organization of the United Nations (FAO) asserts that urban vegetable gardens can be much more ecological and efficient than traditional ones, producing as much as 20 kg of food per year per square metre. We explain to you what this domestic horticulture involves and how to set up a vegetable garden at home.
