A study by Matthias S. Keil found that the brain extracts key information for facial identification primarily from the eyes, while the mouth and nose are secondary. The analysis suggests that faces are responsible for the brain's resolution preference, with a optimum resolution of around 30x30 pixels.
A study by Spanish chemists has detected up to 15 fragrance allergens in baby bathwater, including benzyl salicylate and hydroxycitronellal. The researchers found extremely high concentrations of these substances, exceeding 100ppm, raising concerns about their impact on children's health.
A recent study reviews economic arguments for tobacco control policies, finding that taxes can justify interventions due to market failures. However, the study concludes that a society with smokers is not necessarily economically ineffective, and that measures like taxes and restrictions on consumption may increase net welfare gains if...
Scientists have identified a distinct new species of insect, Tyrrhenoleuctra antoninoi, living on the Balearic Islands. The study reveals genetic differences between this population and others found in the Western Mediterranean region.
Researchers analyze dental wear of herbivorous animals hunted by Homo heidelbergensis to determine vegetation and way of life. The study confirms differing mobility patterns among hominid groups, with some sites showing high and low occupation periods.
Researchers confirm that Mars' surface minerals influence its soil temperature measurements using infrared spectroscopy, with significant increases and falls in reflectance values. This study has implications for NASA's Mars Science Laboratory mission, allowing for more accurate interpretation of data from the soil temperature sensor.
A team of researchers has developed an environmentally-friendly lubricating grease based on ricin oil and cellulose derivatives, providing a 100% biodegradable alternative to traditional industrial lubricants. The new formula offers improved environmental performance and is easier to process than conventional greases.
A study published in Ecology Letters reveals that plants' circadian clocks can improve climate change scenarios by accurately predicting CO2 levels and photosynthesis. The internal clock enables plants to adapt to their environment, surviving and reproducing more efficiently.
A study in Spain found a 17% increase in maternal deaths since 1996, with the highest death rates among foreign women and those aged 35-44. The risk of death rose exponentially with maternal age, highlighting the need for epidemiological monitoring and studying causes to prevent deaths.
Researchers have successfully developed echolocation in humans, allowing blind individuals to identify objects and navigate their surroundings. The technique involves producing specific tongue clicks to detect echoes, with results showing potential for practical applications beyond aiding the visually impaired.
Researchers used a demographic and economic model to evaluate the effect of immigration on the Spanish pensions system, finding that immigrant contributions will exceed native-born contributions by 2055. The study predicts a more pronounced increase in fertility rates among migrants, leading to a decline in pension loads.
A recent study published in The Journal of Headache and Pain found that smoking more than five cigarettes a day increases the frequency of migraine attacks. The research involved 361 medicine students who were aware of their migraine status and reported higher prevalence of smokers among those with migraines.
Researchers from Rovira i Virgili University find that using mud from waste water treatment plants as an alternative fuel reduces CO2 emissions by 140,000 tonnes between 2003 and 2006. This sustainable solution enables cement factories to power their operations without harming human health.
Researchers have identified the largest carnivorous dinosaur tooth in Spain, measuring 9.83cm, and attributed it to the Allosauroidea clade. The tooth's features provide key information about its former owner, a large predatory theropod that likely belonged to the same group as Turiasaurus riodevensis.
Researchers propose effective autonomy of schools to design educational programs tailored to socio-cultural contexts and involve families in managing schools. The study highlights the need for collective consciousness and political will to enact changes in the current organizational structure.
A new study reveals that our brains detect expressions of happiness and surprise faster than those of sadness or fear. The right hemisphere performs better in processing emotions, particularly happy and surprised faces.
Research confirms the transfer of zinc, cadmium, and copper from water to fish tissues in Huelva estuary. The study found positive correlations between metal levels in water and fish tissues, highlighting the impact of pollution on commercially important species.
A study on rural tourists' profile in Spanish villages with limited inhabitants highlights the importance of emotional and cognitive aspects of travel. Key factors influencing traveler behavior include historical-cultural wealth, cleanliness, and welcome from local residents.
Research at Spanish airports reveals poor efficiency levels, mainly caused by excessive decentralization of services, leading to missed opportunities for cost savings and increased production. The study suggests concentrating airport operations in a single site to achieve economies of scale.
The study reveals that human impacts, such as dams and agriculture, are the main cause of sediment accumulation in Catalan rivers. Global warming also exacerbates the problem by reducing river discharge.
A new technique has been developed to evaluate basketball players' performance, using mathematical models that consider multiple factors such as points scored, rebounds, assists, and relative importance. The results show that certain players excel in specific positions, highlighting the need for more nuanced evaluation methods.
The study analyzed fossil remains of small vertebrates in the El Mirón cave, revealing seven periods of cooling and warming in the region's climate. The findings suggest that forest-dwelling rodents flourished during warmer periods, while cold-adapted species survived and migrated to northern Europe.
A new study by researchers at the University of Murcia found that men who consume more fruits and vegetables have better semen quality. The study, which analyzed data from 61 men, showed that higher antioxidant intake is associated with improved sperm concentration parameters.
Researchers have developed an AI-powered music system called Inmamusys that generates emotive and original music in real-time. The system is designed to eliminate repetitive canned music in public places, providing a pleasant musical environment for everyone.
Researchers developed a statistical model to measure extreme wave heights, revealing seasonal variations in different locations. The study's findings have vital importance for coastal management, marine construction, and understanding biological processes.
A recent study published in Sexually Transmitted Diseases found that Spanish prostitutes are least likely to use condoms with their clients. The study, which surveyed 400 female sex workers, revealed that 95.5% of sex workers use condoms during vaginal sex with clients, but only 12.4% do so with their regular partners.
A new method uses laser ablation and multicollector ICP-MS to detect small variations in sulphur isotopes in hair, which can be linked to a person's geographical movements. The technique has been tested on volunteers with different diets and origins, showing promise for tracking international criminals.
