Summer holidays in Spanish schools are amongst the longest in Europe, and every year the debate resurfaces as to whether their length is appropriate or excessive. Do they affect the knowledge and skills acquired? Could they have an impact on well-being? Do they affect all children equally? How could the summer months be improved for children and teenagers?

So far this year, up to 20 August, 262,000 hectares have been burnt in Spain, compared with the average of 105,600 hectares burnt between 2015 and 2024. Large-scale wildfires, exacerbated by climate change, are increasing both in frequency and in the area affected. But what happens in the forests after a fire? Can the woodland regenerate on its own? What criteria should be followed? We analyse, with the help of experts, how these ecosystems recover and what measures are taken to protect and restore them.

Every summer, algal blooms are common, from the Cantabrian Sea to the Mediterranean. Most play essential roles in aquatic ecosystems and have a high capacity to absorb CO₂. However, some can also cause problems, as is the case with the invasive alga Rugulopteryx okamurae, which has been spreading along the Spanish coastline for a decade.

Even though we know it is important to protect ourselves from the sun to reduce the risk of skin cancer, the incidence of melanoma is on the rise in Spain. Why? How common and dangerous is this form of cancer? How can it be treated? In this article, we address key questions about this disease, drawing on expert sources.

To fully experience the astronomical phenomenon of a total eclipse, you need to prepare in advance. The main concern is eye safety, but there are other health risks that can easily be avoided. We explain the main personal precautions to bear in mind.

Air conditioning in buildings is necessary to combat the high temperatures of summers, which are becoming increasingly long and hot; however, it is not without controversy due to its energy consumption and environmental impact. Today, the WHO is presenting its new guidance on health and heat action plans, in which it acknowledges that air conditioning is problematic, while also emphasizing the need for vulnerable populations to have access to these systems. In a recent briefing organized by SMC Spain, we analyzed its role in the fight against global warming.

We often see headlines claiming that new research has found a ‘cure’ for diseases. However, what are the real chances of this being true? How does the current stage of the research affect its ultimate outcome? Has it already been tested on humans, or only on laboratory animals? In this article, we explain why animals are used in biomedicine, the reasons why mice are the most commonly used, the steps and timeframes involved from when a treatment appears effective until it can be determined whether it works in people, the characteristics and limitations of various disease models, and how results should be communicated to inform the public without raising false hopes.

Decades ago, concerns began to be raised about the decline in honeybee populations. Although their situation has improved, the same cannot be said for other pollinating insects. Together, they enable the reproduction of nearly 90% of flowering plants and directly contribute to three out of every four crops that feed the world. We examine the causes of this decline, their current situation, and the measures being taken to protect them.

The European Union is close to passing legislation to facilitate the use of plants edited using CRISPR, a technology that makes it possible to modify the genome of living organisms with precision. The Council of Ministers of the EU is scheduled to deliberate on this legislation on 21 April, and in this article we explain what these techniques are, their potential benefits and risks, and how they will be regulated.
