According to a study published in the journal JAMA Health Forum, the use of the benzodiazepine lorazepam by the character Victoria Ratliff in the series The White Lotus was associated in the United States with an increase in Google searches for this medication, including queries about how to obtain it online. The series generated 1.6 million more searches than usual over a 12-week period. Although the study reflects searches for information and not actual consumption, the abuse of anti-anxiety drugs is a fact: illegal sales of benzodiazepines have increased in the United States, and Spain leads the rankings in terms of consumption.

A team at Google DeepMind has developed AlphaProof, an artificial intelligence system that learns to find formal proofs by training on millions of self-formulated problems. According to the authors, the system “substantially improves upon previous-generation results on historical problems from mathematical competitions.” Specifically, in the 2024 International Mathematical Olympiad (IMO) for secondary school students, “this performance, achieved after several days of computation, resulted in a score equivalent to that of a silver medalist, marking the first time an AI system has achieved medal-level performance.” The results are published in the journal Nature.

In women suffering from post-traumatic stress disorder (PTSD) after experiencing sexual assault, the connectivity between two areas of the brain within the fronto-limbic system is altered, according to a study presented at the European College of Neuropsychopharmacology conference held in Amsterdam (Netherlands). The study, led by a researcher at Hospital Clínic in Barcelona, compared brain images of 40 women with PTSD following a recent sexual assault and 45 control cases. In 22 of these 40 women, communication between the amygdala—which helps process emotions such as fear—and the prefrontal cortex—which helps regulate those emotions—had almost completely disappeared.

Until now, perceived well-being followed a U-shaped curve depending on age, declining – due to worry, stress or depression – until people reached middle age, around 50, and then rebounding into old age. With malaise, the U is inverted and we talk about the ‘unhappiness curve’, shaped like a hump. Now, research published in PLOS One with data from the US and the UK claims that this age-related malaise is declining and that there is no longer such a hump. The reason for the change is said to be the deterioration of mental health among young people, especially those under 25. The study also includes data from 44 countries between 2020 and 2025, including Spain, and confirms that the malaise no longer takes the form of a hump, but decreases with age.

Research estimates that 15.6 million people born between 2008 and 2017 worldwide will develop gastric cancer at some point in their lives if current trends continue. In Spain, there would be 58,641 cases, or 1.24% of people in this age group. The team used data on gastric cancer from 185 countries in 2022 combined with mortality projections based on United Nations demographic data. The estimates, published in the journal Nature Medicine, show that 76% of cases could be attributed to Helicobacter pylori, a common bacterium found in the stomach.

A study evaluating the mathematical and linguistic performance of first- and second-year primary school students in France—more than 2.6 million children between 2018 and 2022—shows that the gender gap in mathematics appears within a few months of starting primary school. This gap increases with years of schooling, not with age, adds the research published in Nature.

The number of adolescents with anxiety problems seems to be increasing, especially in developed countries. An opinion article published in the journal Science proposes that maternal stress, quality of care and environmental conditions in the early years, together with current social and technological changes, may contribute to explaining this trend. 

The report Participation of women scientists as expert sources in the media: motivations and obstacles, carried out by FECYT's SMC España with the Gureiker research group (UPV/EHU) analyses the data from a survey, a pioneer in Spain, on the factors that influence the media participation of scientists as expert voices. All the people contacted as information sources by the SMC Spain team were surveyed over a three-month period, starting in March 2024. Of the sources consulted, 43.91% were women and 56.09% were men. However, of the total number of people who accepted SMC's proposals and appeared as sources, 37.66% were women and 62.34% were men. The greater media exposure of male scientists benefits them for future interventions. In terms of barriers that prevent researchers from speaking in the media, lack of time due to family responsibilities affects female scientists (22.95 % of respondents) more than male scientists (10 %).  

An artificial intelligence (AI) model led by the company Meta is capable of translating speech and text, including direct speech-to-speech translations, from up to 101 languages in some cases. According to the research team, this model - called SEAMLESSM4T - can pave the way for fast universal translations ‘with resources to be made publicly available for non-commercial use’. The work is published in the journal Nature.

The report 'Experiences of researchers who interact with the media and social networks in Spain', carried out by FECYT’s Science Media Centre Spain (SMC) in collaboration with the research group Gureiker, from the University of the Basque Country, analyses data from a survey, the first of its kind in Spain, on the relationship with the media and social networks of the expert sources contacted by the SMC Spain from March 2022 to July 2024. The results show that scientists have a positive or very positive perception of their participation in the media (83.12%). However, 51.05% of respondents admit to having suffered an attack after communicating science. Women receive significantly more attacks than men: 56.86% of female scientists report attacks compared to 46.21% of male scientists. The social network X (formerly Twitter) is the most common avenue for this type of attack.
