Conventionally, social researchers analyse media messages by reading text and coding it. This is time consuming and restricts many studies to small samples. Nowadays very large amounts of text are

Communication is key in the field of health. Including communication tools such as Instagram in youth health fieldwork poses a number of challenges, but also has the potential for social health research.

The present article reviews the role of the media in the dissemination of tobacco-related information and the evolution in tobacco control policies that the approach has caused.

Reviewing public communications emitted during health crises in the last thirty years is useful for verifying that there are a number of repeated mistakes: for example, untrained spokespeople with poor

Rare diseases (RDs) are those that affect fewer than five people in every 10,000. There are around 7,000 RDs, they are difficult to diagnose and very few have a treatment.

We are becoming more vulnerable. The feeling of general uncertainty comes from the fact that we live through several crises at the same time. In a world dominated by consumerism

The Preamble of the Constitution of the World Health Organization reminds us that «Informed opinion and active cooperation on the part of the public are of the utmost importance in

Good communication is fundamental in the promotion and maintenance of individual and collective health. Despite the vast amount of information we can currently access, misconceptions still persist in fundamental topics

L'única manera d'explicar l'estrany cas del guaiac és recórrer a la campanya de publicitat que va promoure la família Fugger per a fomentar-ne l'ús.

We have created a globalized society, but it is not only human populations that are increasingly interconnected. The movement of invasive species and disease vectors along our expanding routes of

Documentary text on how chromosomal inversions in natural populations of the species Drosophila subobscura are good indicators of climate change and can help us to study how organisms adapt to it.

Valerie Jane Morris Goodall won the XXVII Premi Internacional Catalunya this year. It is a perfect occasion to summarise a very long story. In 1958, Jane Goodall travelled to Kenya

It is clear that there are not only five dwarf planets, but probably many more, possibly thousands.

What do you see in the picture accompanying this article? The answer will probably be: «two dalmatian dogs, sitting and looking at the front». But they are nothing but black spots over a white background.

The work of economists, which is so important, is ascribed to the field of human decisions. These are emotional and, therefore, irreducible to the scientific method.

Urey and Miller recognized that the overall chemical processes that take place on the surface of the Earth involved three general components: energy, the atmosphere, and the oceans.

Titan’s atmosphere hosts a complex organic chemistry in the solar system starting with nitrogen and methane and leading to the formation of hydrocarbons and nitriles, including prebiotic molecules.

The concept of an RNA world is a hypothesis firmly rooted in empirical data and is part of a long and complex scientific perspective that goes back more than fifty years to the discovery of the central role RNA.

Carbonaceous chondrite meteorites are carbon-containing fragments of primitive asteroids that have offered the only samples available to date giving insights into chemical evolution in laboratory analyses. Their study has revealed that abundant organic chemistry came to be in the Solar System ahead of terrestrial life and, by the input of these meteorites and comets, might have aided in the origin of our planet’s biochemistry.

The question of the origin of life cannot be explained by appealing exclusively to Darwinian evolutionary mechanisms, as many experts tend to assume, but requires a profound change in perspective.

The cenancestor is defined as the last common ancestor of every currently living being. Its nature has been inferred from the identification of homologous genes between archaea, bacteria, and eukaryotic lineages. These inferences indicate that the cenancestor had a relatively modern protein translation system, similar in complexity to that of a current cell. However, the key enzymes for the replication of genetic material and for cell membrane biosynthesis are not homologous in bacteria, archaea, and eukaryotes. Here, we briefly review the history of the concept of the last universal common ancestor and the different hypotheses proposed for its biology.

«The question of the origin of life is one of the fundamental problems of science.» Few would disagree with this statement by the Russian biochemist Alexander I. Oparin, pioneer in

The expected effects of global environmental change over the coming decades may worsen the situation for many currently endangered Valencian plants, even leading to the localised extinction of some species
