A new study published in PNAS reveals a causal link between dopamine and the reward responses in humans when listening to music. Researchers found that dopamine manipulation led to opposite effects on musical pleasure and motivation, with levodopa increasing hedonic experience and risperidone reducing both.
A study by University of Barcelona researchers found that the green turtle reintroduction program in Cayman Islands has successfully recovered the species' population, with a high genetic diversity. The program's success is attributed to careful management and monitoring, ensuring the long-term survival of the species.
A recent study reveals that permafrost temperatures have risen globally, with continuous permafrost warming by 0.39°C and discontinuous permafrost by 0.20°C between 2007 and 2016. This increase in permafrost temperature has severe consequences, including the release of carbon dioxide and methane, which speed up global warming.
A new study suggests that snoek species may recolonize the Beagle Channel and Southern Western Atlantic, negatively impacting hake populations and regional economies. Researchers analyzed ancient zooarcgaeological remains to reconstruct trophic networks in the region.
Patients with type 1 diabetes exhibit altered brain connectivity patterns compared to healthy individuals, according to a new study published in PLOS ONE. The research, led by the University of Barcelona, employed fMRI techniques to investigate brain activity during working memory tasks.
A new study published in the Biodiversity Data Journal reveals a total of 20,539 samples of different Iberian spider species, with 11 new species discovered. The research highlights the lack of knowledge on Iberian spiders and emphasizes the need for standardized protocols and wider taxonomical data to protect their conservation.
A new study has detected bacteria from humans in Antarctic and Subantarctic marine birds, revealing the fragility of polar ecosystems. The research highlights the risk of massive deaths and extinctions of local fauna populations due to pathogens introduced by human activity.
Salinization affects biodiversity and water ecosystem functioning directly, but more baseline information is needed to predict its effects. The main causes of salinization in Spain include mining, agriculture, and regime changes in precipitations.
Researchers identified conserved genes involved in regeneration across species, including flies, mice, and zebra fish. They also discovered new types of regulatory elements that can be activated to boost organ regeneration.
Researchers analyzed severe influenza cases in Catalan hospitals to study vaccination effectiveness in reducing ICU admissions and deaths. Vaccination showed 23% effectiveness overall, with 44% for those over 65.
A study analyzing over 50,000 genomes identified 12 specific DNA fragments related to ADHD vulnerability, highlighting a polygenic hereditary basis and functional relevance. The research also reveals genetic overlaps with major depression, obesity, and other conditions.
Researchers from Tohoku University and the University of Barcelona have developed an in vitro neural circuit model that reproduces complex brain-like functions. The study reveals the importance of modular organization for maximizing flexibility in neural circuits, as well as the potential of biophysical models to understand collective ...
Researchers from the University of Barcelona used chironomid subfossils to reconstruct Holocene temperatures in the Iberian Peninsula, showing a rise in temperatures during the Holocene Climate Optimum and a decline after its onset. The study provides a promising tool for understanding climate evolution and natural changes.
Researchers have developed a non-invasive method to detect metallic stents and their potential structural failures through microwave spectrometry. The technique showed promise in detecting stent fractures and restenosis, highlighting the potential for new approaches to cardiovascular disease treatment.
Researchers found that diatom algae blooms produce biotoxins affecting Oikopleura dioica zooplankton development, causing 'golf ball' phenotype and lethal anomalies. The study suggests a potential biomarker for zooplankton response to stress caused by diatoms.
A study by University of Barcelona researchers finds that global warming will increase burned areas due to fires in Mediterranean Europe, with a 40% rise at 1.5°C warming and 100% at 3°C. This calls for rethinking current management strategies and developing climate-fire models to prevent and reduce fire impact.
Researchers develop new theory to explain how tumors spread, revealing competition between forces that shape their growth. The 'active wetting' model suggests tumors behave like active drops, with cells creating forces and moving on their own.
The Gaia satellite has detected substructures in the Milky Way's star disk, indicating a 300-million-year-old gravitational disturbance caused by the Sagittarius Dwarf galaxy. Researchers used precise data to analyze shapes and twisting patterns, leading to new findings on galactic archaeology
A scientific study has found that sleep apnea can favor lung cancer growth in young individuals, suggesting that age may play a role in the disease's aggressiveness. The research team hopes to identify and prove physiopathological consequences of sleep apnea to develop personalized medicine strategies.
Researchers analyzed ecological features and DNA sequencing data to reconstruct the tree of life of aquatic macroinvertebrates in Europe. They found that oldest lineages have higher functional diversity than younger ones, which is influenced by their ability to colonize new habitats.
A new study identifies a disease affecting the starfish Odontaster validus, one of the most common species on the Antarctic sea floor. The disease has afflicted up to 10% of the population, causing tissue damage and altering the natural balance in marine ecosystems.
An international study highlights key questions for a more sustainable environmental future in Europe, focusing on the impact of chemical products on biodiversity, natural ecosystems, and human health. The study aims to inform policy decisions and research priorities to mitigate these risks.
Researchers have identified 40 genes related to aggressive behavior in humans and mice, shedding light on the genetic basis of aggression. The study suggests a shared genetic base between aggressiveness in children and adults and Attention Deficit Hyperactivity Disorder (ADHD), as well as with major depression.
A new study led by Francisco Ramírez from the University of Barcelona identifies key areas to protect 20% of sea bird populations in Patagonia. The research uses a multidisciplinary approach to define marine areas of interest in conservation, considering ocean currents and coastal ecosystems.
