A study by University of Arizona researcher Caleb Warren found that people perceive those who smile as more genuine and likable. In contrast, being inexpressive can make someone appear cold rather than cool. The researchers tested this theory using advertisements featuring various endorsers, including James Dean.
A new study led by University of Arizona cognitive scientist Aneta Kielar found that people with primary progressive aphasia, a rare dementia, can recruit intact areas of the brain to decipher sentences. This brain compensation offers hope for developing targeted treatments for PPA.
Research finds that young adults' own financial behaviors have the most impact on their well-being, followed by their romantic partners' behaviors. Parents' financial expectations had the least impact, but still influence young adults' objective financial knowledge. The study suggests that even in non-marital relationships, a partner's...
Researchers used tree-ring records to analyze Mongolia's 2,060-year climate history. The study found that future droughts are likely no worse than those of the past, with increased precipitation offsetting the effects of higher temperatures on semi-arid regions.
Researchers found that frequent use of first-person singular pronouns may indicate a tendency towards negative emotionality, rather than depression alone. High levels of 'I-talk' were linked to anxiety and other negative emotions, suggesting it could be a broader risk factor for mental health concerns.
Research finds that women report higher levels of incivility from other women than men do, particularly if they defy gender norms by being more assertive. The study suggests companies should re-evaluate their cultures and address this issue to create a positive work environment.
A study found that seeing more exercise-related posts from friends can make people concerned about their own weight and body image. However, for some individuals, these posts can also motivate them to exercise and feel better about it.
A team of archaeologists uses LiDAR technology to map a significantly larger area of Ceibal in Guatemala, uncovering over 15,000 ancient Maya architectural remains. The resulting map covers 470 square kilometers and provides a detailed timeline of growth and change at the site.
Researchers found that the northern Galápagos Islands have been warming by almost 0.4 degrees F per decade, with temperatures increasing overall by about 1.1 degrees F since the 1970s. This finding is significant because it suggests that the region's reefs are more vulnerable to climate change than previously thought.
Researchers found that prescribed fire reduced bird species diversity, while mastication led to a 50% decrease in bird species and 60% reduction in total numbers of birds. The study suggests that current fire management practices harm wildlife and increase fire risk.
New research from the University of Arizona contradicts the Toba catastrophe hypothesis by showing no significant negative impact on vegetation growing in East Africa after the 74,000-year-old volcanic eruption. The study found some die-off of mountain plants just after the eruption, but no massive die-off of vegetation at all elevations.
Researchers at the University of Arizona used a novel technique to observe electrons moving through crystals, shedding light on the unique properties of transition metal dichalcogenides. The study revealed that electrons move differently within and across layers, with implications for future processing technologies.

Researchers projected that record-breaking temperature jumps and accompanying extreme weather events will become more frequent unless greenhouse gas emissions decline.
A new study by researchers at the University of Arizona found that people with high levels of biospheric concern are more likely to experience stress and depression due to climate change. Those who show concern for the environment, animals, and plants tend to have a planetary outlook and think about bigger picture issues.
Researchers found that increased fluctuations in the jet stream's path since the 1960s coincide with more extreme weather events, including heat waves, droughts, wildfires, and flooding. The study used tree ring data to reconstruct historical changes in the North Atlantic jet stream prior to the 20th century.
Researchers found that language learners prefer word orders with shorter dependencies, which are easier to process, suggesting a causal link between human cognition and language structure. This discovery provides new insights into the role of human information processing in shaping linguistic universals.
A new study projects that groundwater recharge will increase in the northern US and decrease in the south as climate change takes hold. The research used global climate models and found varying effects across different hydro-climatic regions, highlighting the need for better management and policy.
A new study from the University of Arizona finds that people with poor social skills are at greater risk for mental and physical health issues due to increased stress and loneliness. Social skills training has shown to be effective in improving these skills.
Researchers at the University of Arizona found that even with perfect natural selection, aging would still occur due to cancer cells cheating the system. Slowing down one type of cell can lead to an increase in another problematic cell type, making it mathematically impossible to halt aging.
A team of scientists at the University of Arizona has discovered that a newly evolved yeast protein can fold into a compact three-dimensional structure, contrary to the long-held assumption that such proteins are incomplete and 'works-in-progress',
A team of University of Arizona researchers has discovered that a previously thought to be small turquoise mine was actually a significant source of the mineral, producing 25% more turquoise than previously estimated. The study uses both archaeology and geochemistry to gain a complete picture of operations at the mine.
