GLP-1 drugs such as semaglutide (Ozempic, Wigovy, Libersus), which are commonly prescribed for diabetes and obesity, may also be associated with improved mental health, according to a new study. The study found that people using these drugs had fewer psychiatric visits and less time off from work due to mental health problems. This large-scale analysis was conducted by researchers from the University of Eastern Finland, Karolinska Institutet in Stockholm, and Griffith University in Australia. Obesity and diabetes are both associated with an increased risk of mental health problems. At the same time, people with mental disorders are more likely to…

New research published in translational psychiatry Researchers suggest that miniature brain models produced in the lab can reveal different patterns of electrical activity in different types of autism. By analyzing brain tissue grown from patients’ urine samples, the scientists provided evidence that these models can accurately distinguish between neurotypical people and people with various autism profiles. These discoveries tend to provide new ways to understand the biological causes of autism and test individualized treatments. Autism is a neurodevelopmental condition characterized by differences in social communication and restricted and repetitive behaviors. Although some cases are associated with a specific genetic mutation…

Researchers at the University of Konstanz have identified a completely new type of sliding friction. In this case, resistance to movement occurs even without physical contact, but instead from the collective action of the magnetic elements. Their findings show that friction does not always increase steadily with load, as described by Amonton’s law (one of the oldest and most widely accepted rules of thumb in physics), but can reach distinct peaks when the magnetic order in the system is disrupted. For more than 300 years, Amonton’s law has directly related friction to the amount of force pushing two surfaces together.…

A simple hand stencil found on the wall of an Indonesian cave has been confirmed to be the oldest known rock art on Earth. This is at least 15,000 years older than previous discoveries in the same region. An international research team led by Griffith University, Indonesia’s National Research and Innovation Agency (BRIN) and Southern Cross University has determined that the Sulawesi paintings are at least 67,800 years old. Researchers say the breakthrough will help them understand when and how humans first arrived in Australia. The people who created Sulawesi’s art likely had close ties to Australia’s indigenous ancestors. Ancient…

New research published in Computer reports on human behavior It suggests that efforts to make artificial intelligence more inclusive may introduce new and unanticipated biases. The scientists found that common artificial intelligence models tend to over-attribute stereotypically masculine behaviors to female characters and judge violence against women to be significantly more unpleasant than violence against men. These findings provide evidence that programming models to be sensitive to gender equality can inadvertently lead to extreme ethical contradictions. Scientists launched this study to better understand how artificial intelligence systems handle gender and morality after initial training. During development, these models undergo a…

A team of astronomers led by Carnegie has discovered the clearest evidence yet for the presence of atmospheres on rocky planets outside our solar system. Using NASA’s James Webb Space Telescope (JWST), researchers have identified signs of gas around an unusual target: an ancient, extremely hot super-Earth whose surface is likely covered in lava. The survey results are Astrophysics Journal Letter. The planet, known as TOI-561 b, has about twice the mass of Earth, but is dramatically different in almost every other way. It is extremely close to its star, orbiting at only 1/40th the distance from the Sun to…

New interdisciplinary research presented at nature Tracing over 2,000 years of population history in Argentina’s Uspallata Valley (UV), an important southern tip of ancient Andean agriculture. This research provides new insights into how agriculture reshaped society and how people coped with long-term hardship. By combining ancient human and pathogen DNA with isotopic data, archaeology, and paleoclimate records, and working closely with Hualpe indigenous communities, the research team revealed how local hunter-gatherers adopted agriculture, how subsequent maize-based societies faced sustained stress, and how strong family bonds helped people endure precarious conditions. One long-standing question is whether agriculture spread primarily through migrant…

In a surprising stroke of luck, NASA’s Hubble Space Telescope observed a comet in the process of breaking up. The probability of witnessing such an event at exactly the right moment is very low. The research results were published in a magazine Icarus. Comet K1, officially known as C/2025 K1 (ATLAS) (not to be confused with interstellar comet 3I/ATLAS), was not the intended focus of Hubble’s observations. “Sometimes the best science happens by chance,” says study co-author John Noonan, a research professor in the physics department at Auburn University in Alabama. “This comet was observed because after we won the…

Researchers at the University of São Paulo’s Center for Agriculture and Nuclear Energy (CENA-USP) have identified multiple types of antibiotics in the Piracicaba River, a major waterway in the Brazilian state of São Paulo. Their discovery is environmental science europeindicating that these substances are not only present in water, but also accumulate in fish. The research team also found that common aquatic plants in the area Salvinia auriculatacould help reduce this contamination. This study was led by Patricia Alexandre Evangelista with support from FAPESP. The study combined several approaches, including environmental monitoring, studying how pollutants accumulate in organisms, analyzing genetic…
