Social contact gives young fish larger brains

Stockholm University
Peer-Reviewed Publication

Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. The findings suggest that live social interaction in real time may be important for brain development.

Five UJI researchers rank among the 300 most prominent women scientists in Spain

Universitat Jaume I
Grant and Award Announcement

Five researchers from the Universitat Jaume I of Castelló in the fields of psychology and chemistry have ranked among the top 300 Spanish and international women scientists working in Spain, according to a ranking based on public Google Scholar profiles and equivalent OpenAlex indicators.

The ranking, compiled by Isidro F. Aguillo at the Cybermetrics Lab of the Institute of Public Goods and Policies of the Spanish National Research Council (IPP-CSIC), aims to increase the visibility of women researchers through open-access platforms such as Google Scholar, ORCID and OpenAlex, which provide broader coverage than other bibliometric sources, including subscription-based databases. It also seeks to promote open infrastructures through the wider use of personal ORCID identifiers and institutional ROR identifiers.

The 2026 edition of the ranking includes a total of 12,110 researchers ranked according to the global impact of their research, 122 of whom belong to the public university of Castelló. The full ranking can be consulted in the author’s publication.

Disgust may contribute to improper waste disposal

University of Gothenburg
Peer-Reviewed Publication

A common explanation for why waste management sometimes fails is that carelessness breeds more carelessness. Now, research from the University of Gothenburg shows that dirty waste disposal rooms can evoke feelings of disgust that increase the risk of people disposing of their waste incorrectly.

Three Spanish universities promote RESINA, a project to mobilize the innovative potential of rural areas

Universitat Jaume I
Grant and Award Announcement

The interuniversity project Roots of Resilience: Rural Knowledge for a Sustainable Future (RESINA) has been launched with the aim of identifying, validating and transferring sustainable ways of living that emerge from the heart of rural Spain. Researchers from three universities (Universitat Jaume I of Castelló, the Public University of Navarre and the University of Cádiz) are leading an initiative that seeks to transform the prevailing narrative about rural areas, highlighting their value as key spaces for social innovation and collective resilience in the face of the major challenges of the 21st century: the ecological emergency, depopulation and social fragmentation.

Funded by the Ministry of Social Rights, Consumer Affairs and the 2030 Agenda, the project will focus on documenting practices based on neighbourly cooperation, agroecology, the social economy, mutual care and communal resource management that have enabled rural communities to sustain themselves under adverse conditions.

Conditional Medicaid expansion and mental health outcomes in Georgia

JAMA Network
Peer-Reviewed Publication

About The Study: In this difference-in-differences analysis of national surveillance data, Georgia’s Pathways to Coverage program was associated with worsening mental health among low-income adults. These findings suggest that conditioning Medicaid eligibility on work or community engagement requirements may create additional barriers to coverage and mental health care access, with potential implications for population health and equity.

We do not have a decider in our brain

Indiana University
Peer-Reviewed Publication

Decisions have long been defined as the intermediate stage between perceptions and actions with each stage of this linear causal sequence corresponding to a discrete brain function, from sensory to cognitive to motor. Indiana University cognitive neuroscientist Tom James challenges this view by arguing that in place of a discrete decision-making function in the brain that causes actions, a combination of sensory, sensorimotor, and motor processes lead to what he prefers to call ‘action selection.’

Got beef with beans? SFU study explains why shoppers don’t buy more plant‑based proteins

Simon Fraser University
Peer-Reviewed Publication

Incorporating more plant-based proteins could help people save on their grocery bill, but new research has found that it's not so simple when it comes to choices at the supermarket.

Simon Fraser University researchers peeked into more than 87,000 grocery carts in Canada and Finland to study how much price influenced the type of protein people bought: animal-based or plant-based. Researchers discovered that while the price had to be right, having a variety of options also played a role.
