The Prime Minister, Pedro Sánchez, announced on Tuesday from Dubai that Spain will ban children under the age of 16 from accessing social media and will adopt other measures to increase control over digital platforms and ensure that their executives are held accountable for violations. Sánchez made this announcement in his speech to the plenary session of the World Government Summit and announced that next week the government will approve a series of measures, including this ban.

A US research team has devised a method that uses a browser extension to alter the algorithm of X (formerly Twitter) to study its impact on user behaviour. In a 10-day experiment with 1,256 volunteers during the 2024 US presidential campaign, they used the method to vary the content expressing anti-democratic attitudes and partisan hostility. According to the authors, the results—published in Science—provide causal evidence that greater or lesser exposure to this type of content alters polarisation in the same way. Their conclusions contradict previous research published in the same journal, which found no such relationship on Facebook or Instagram. In that case, the study was conducted in collaboration with and funded by Meta.

A study published in Scientific Reports concludes that adults who use Instagram very frequently overestimate their ‘addictive’ use, which complicates self-control and increases feelings of guilt. According to the research, excessive use, in most cases, is not an addiction but a habit. The study was conducted on more than 1,000 Americans and suggests that the fact that many think they have an ‘addiction’ may be related to the media's frequent use of this term when talking about social media. 

Avoiding social media for a week can reduce symptoms of anxiety, depression, and insomnia, according to a study published in JAMA Network Open. The study measured the mental health of a group of 373 people aged 18 to 24 in the US before and after a week without using Facebook, Instagram, Snapchat, TikTok, or X. The authors caution that the durability of these results and their associations with behaviour require further research.

A study by the University of Cádiz has identified six factors that drive polarization around health-related issues, for example during crises such as the COVID-19 pandemic: political ideology, misinformation, social media dynamics, trust in institutions and professionals, risk perception, and socioeconomic factors. This review, published in Science Advances, brings together the conclusions of 90 previous studies and analyzes how these determinants exacerbate health inequalities and influence compliance with public health measures.

A team has analysed data from a survey of more than 3,000 teenagers aged 11-19 in the UK. Their findings show that those with mental health problems spend an average of 50 minutes more per day on social media than those who do not suffer from them. According to the authors, who publish the results in the journal Nature Human Behaviour, further research is needed to know if this is a causal relationship.

Power shortages left millions of people in the Iberian peninsula and parts of southern France without electricity on Monday. The situation was exacerbated by the failure of telecommunications, which were vulnerable to the power failure.

Around half of the 100 most popular videos on TikTok about Attention Deficit Hyperactivity Disorder (ADHD) contain statements that diverge from the scientific literature of reference, according to a study published in PLOS ONE. In addition, the research shows that there are discrepancies between young people and mental health professionals about the educational value of the content about ADHD on this social network.

According to a study published in Science, social media content containing misinformation provokes more moral outrage than content containing accurate information, and this outrage facilitates the spread of misinformation. In addition, the results also showed that people are more likely to share this outrage-provoking misinformation without reading it first. 

A meta-analysis by the University of Valencia has studied the links between leisure reading habits on digital devices and the reading comprehension of students of different ages. The research - which is based on 25 studies published between 2000 and 2022 involving some 470,000 students from different countries - concludes that in the early stages (primary and 1st and 2nd ESO in the Spanish case) there were small negative relationships between digital leisure reading and reading comprehension, while in later stages (3rd and 4th ESO, baccalaureate and university) the relationship became slightly positive. The research is published in Review of Educational Research.
