Nearly three and a half million Ukrainians have fled their country; half of them are children. Ensuring their physical well-being is a priority, but we cannot forget the effect that war can have on children's mental health.

The publications in which scientific results are made public, known as papers in the jargon, are sometimes newsworthy, that is, what they report can be narrated to a wider - non-scientific - audience as journalistic news. But in the paper-news transition the message is formatted very differently.

Scientific studies are regularly published in various scientific journals. Science journalists who have contacted the journal and registered have prior access to them under an embargo that they undertake to respect. This is an advantageous system, but it is not without its critics.

Not all studies are revolutionary and not all researchers are free of conflicts of interest. This Decalogue of common mistakes aims to help you write about science with rigour and, above all, putting the public first.

Thousands of scientists around the world have spent decades studying the Earth's climate and how its evolution is affecting life on the planet, including human life. Their work is channelled through the UN's Intergovernmental Panel on Climate Change (IPCC), whose regular reports are an unprecedented effort to reach consensus on what has been learned and communicate it in a way that is useful for decision-making. We offer a quick update on the climate crisis.

"At present, it is not possible to know exactly when and how a volcano may erupt," explains the National Geological Institute (IGN). In other words: it pays to be prepared. Even if you are a journalist. These resources make it easier.

The monographs of the International Agency for Research on Cancer (IARC) cause controversy in the public debate when they analyze topics such as meat and cell phone radiation. Interpreting their work rigorously is not easy: in this guide we try to help contextualize their studies.

Journalists are not the only generators of information content, but they certainly are the ones who are trained to select, channel, and amplify truthful information and combat misinformation. In crisis situations, where scientific evidence guides decision-making, science communication to society takes on an almost strategic role. Here are some key points for scientists talking to journalists at such times.

Every day, all over the world, hundreds of press releases about scientific studies travel from the communication offices of research centres to the computers of journalists. Their mission is to attract the attention of their recipients and eventually get their stories published by the media. Here are some tips on this process.
