Climate change is impacting the United States in very different ways depending on region, according to a study published in . PLOS climate. María Dolores Gadea Rivas, a researcher at Spain’s University of Zaragoza, and Jesús Gonzalo, a researcher at Spain’s Universidad Carlos III, found that patterns of global warming vary widely across countries, pointing to the need for region-specific responses. Climate change is a global problem, but its effects are not evenly distributed. The progress of global warming is determined by local conditions. This means that policies and adaptation strategies need to be tailored to specific regions. Compared to…
Recent research published in Journal of social and personal relationships provide evidence that youth who hold hostile sexist beliefs are more likely to engage in behaviors intended to undermine the social relationships of their peers. The findings suggest that challenging traditional gender norms among young people may not only reduce prejudice but also improve the way young people interact with each other. Scientists typically study aggressive behavior by focusing on predictors related to small social circles, such as family and school environments. This approach tends to overlook how broader societal beliefs, such as gender and power expectations, influence human interactions.…
Imagine star-shaped cells in your brain extending long, thin extensions to surround nearby neurons. These cells are called astrocytes. Scientists have long believed that astrocytes function primarily as caretakers, holding neurons together and keeping brain circuits running smoothly. Now, new research is challenging that idea. These widely distributed “support cells” appear to be as important as neurons when it comes to the formation and control of fear memories. “Astrocytes are intertwined between neurons in the brain, and it’s hard to imagine that they’re just there for housekeeping. We wanted to understand what astrocytes actually do, and how they shape neural…
LOS ANGELES — People may think that if they’ve been drinking a little during the week or month, then having a heavy drink every now and then on a Friday or Saturday won’t harm their liver. New research suggests not, according to a study from USC’s Keck Medicine published today. Clinical gastroenterology and hepatology. Researchers have found that people with metabolic dysfunction-associated fatty liver disease (MASLD), the nation’s most common liver disease that affects one in three adults, face a significantly higher risk of liver fibrosis, or harmful scarring of the liver, if they engage in episodic heavy drinking. Episodic…

A single dose of psilocybin can produce lasting changes in a person’s values in life, including increased appreciation for life and deeper self-acceptance. These lasting changes appear to be caused by certain acute effects of the drug, particularly the deep feelings of togetherness and euphoria. The results of this study were recently published in the Journal of Psychopharmacology. Psilocybin is an active chemical found in certain types of mushrooms. This is a classic psychedelic drug that temporarily alters human perception and mood. This chemical primarily works by binding to specific serotonin receptors in the brain. Serotonin is a chemical messenger…
A new study suggests that as stars age, they may be killing off the giant planets they orbit closest to. The study, led by astronomers from University College London and the University of Warwick, provides new evidence that these planets can be pulled inward and destroyed as their host stars evolve. Stars like our Sun will eventually run out of hydrogen fuel. When that happens, they begin to cool and expand, entering a stage known as a red giant. Scientists estimate that the Sun will reach this stage in about 5 billion years. The new discovery is Royal Astronomical Society…
New research published in Journal of social and personal relationships Parents and their adult children have been shown to often share similar preferences regarding the characteristics they look for in future spouses in younger generations. This study suggests that these shared values, particularly an emphasis on economic security, are strongly associated with the type of parenting children experience as they grow up. Choosing a life partner requires balancing personal romantic desires and family expectations, which tends to create tension between parents and children. According to evolutionary theory, adult children prefer traits associated with physical vitality and health, which are indicative…
A group of undergraduate students at the University of Chicago used data from the Sloan Digital Sky Survey (SDSS) to identify one of the oldest known stars in the universe. This star was not born in our galaxy. Instead, it formed in a nearby companion galaxy and later migrated to the Milky Way. The discovery was made by 10 students enrolled in the university’s Astrophysics Field Course, led by Professor Alex Gee, deputy project scientist at SDSS-V, and graduate teaching assistants Hilary Anderes and Pierre Thibodeau. How big data led to major discoveries SDSS is a global collaboration involving more…
Discovered in 2011, MXenes are a rapidly expanding family of ultrathin inorganic materials. They are made from a stack of transition metals combined with carbon or nitrogen, with atoms attached to their outer surfaces. These surface atoms are not just decorative. These play a central role in how the material behaves. “They have a strong influence on how electrons move through the material, how stable the material is, and how it interacts with light, heat, and the chemical environment,” explains Dr. Mahdi Ghorbani-Asl from the HZDR Ion Beam Physics and Materials Laboratory. Until now, most MXenes have been manufactured using…
