Science has shown us that alcohol use disorder is a chronic and relapsing disease, but talking about it in our culture is still complicated.
As with other animal species such as crayfish, drugs activate our brain's reward system to induce a false signal announcing the arrival of a great benefit for our survival.

In Lamarck's revolutionary work, only his failed attempt to elaborate a coherent theory of the evolutionary process has remained in popular teaching.

The year 2020 ended with a potential detection by the Breakthrough Listen project of an artificial signal coming from Proxima Centauri. But there was no indication of structure or modulation in the signal, no evidence that it carried any information.
Animal colourations and the patterns they generate provide some of the best examples of evolution by natural selection. One of the most studied aspects has been camouflage.
Maria Garcés-Sánchez, specialist in paediatrics and researcher in the Vaccines Area at FISABIO, explains why vaccinating children against COVID-19 is not a priority at the moment.
The vaccine protects us against severe forms of COVID-19, but does it prevent us from catching it or infecting others?
The author proposes to create the concept of «pre-scientific dissemination» to talk about scientific mysteries, enigmas, or hypotheses that could be confirmed or disproved by science.
The WHO published recommendations on how to name new infectious diseases to avoid stigmatising a country, community, or economic sector.
We have all inherited DNA sequences from forgotten ancient ancestors
An analysis of our historical relationship with viruses to understand the reactions to the present pandemic.
The number of species catalogued as fluorescent increases each day, and UV lights can help us to find some that are only active during the night, generating a wide range of creative resources to photograph them.
The street lights prevent us from gazing at their wonders and phenomena of the night sky.
If we were to use electrodes to extract energy from ourselves, we would collapse because we would have nothing left to keep our hearts beating.
