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.

Why do eclipses occur? Is the Earth’s shadow responsible for the phases of the Moon? Is the Moon full during a solar eclipse? These are by no means obvious questions, yet they are extremely useful in teaching astronomy for identifying the obstacles we encounter when thinking about celestial mechanics, regardless of age or educational background. Here are several suggestions for untangling the most common misconceptions and understanding the cosmic dance of the stars as seen from Earth.

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.

Premature births, babies born with birth defects, bad luck, satellite and telecommunications failures… Eclipses are attributed with a wide variety of consequences that have no scientific basis and are largely rooted in cultural traditions and deep-seated misconceptions. With the help of expert sources, in this article we explain why some people believe in them, what the main risks are and how to counter them. 

How much homework do teachers assign? If children spend more time doing homework, do they get better grades? What should homework be like in order to be useful? There are conflicting opinions on this subject, as well as a great deal of academic research. In this article, we present evidence to unravel some of the controversies –with a focus on primary education, which is usually completed between the ages of six and twelve.
