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…

A newly identified subsurface freshwater system beneath the Great Salt Lake is becoming more apparent thanks to a study that used airborne electromagnetic (AEM) surveys to map the geological formations beneath Farmington Bay and Antelope Island along the southeastern edge of the lake. Researchers at the University of Utah analyzed the data and found that fresh water filled the sediments beneath the salty lake’s surface, reaching a depth of 3 to 4 kilometers, or about 10,000 to 13,000 feet. The helicopter survey was carried out last year after scientists observed freshwater gushing under pressure on parts of Farmington Bay’s exposed…

MADISON, Wis. (AP) – A year ago, federal environmental regulators told West Virginia officials that a plan to remove sulfur and smog from the air above a state conservation area wasn’t good enough because more than a dozen coal-fired power plants didn’t analyze whether they needed better pollution controls. Six months later, the Environmental Protection Agency is now under the firm control of President Donald Trumpcongratulated the same plan, saying that as long as visibility hits the predicted benchmarks, no evaluation of the technology is necessary. Conservationists say West Virginia’s reversal is just one example of how the Trump administration…

In various types of military conflicts, people with conservative political views are more likely to accept unintended civilian deaths than those with liberal views. This ideological divide is consistent whether the war is against a real adversary, a strategic partner, or a completely fictitious state. The results of this study were recently published in the European Journal of Social Psychology. Public opinion plays a major role in how governments wage war and respond to international conflicts. Tolerance for civilian casualties can have implications for diplomacy, military strategy, and humanitarian aid. The researchers wanted to understand what causes the deep political…

Analysis of research data on the cognitive development of the adolescent brain shows that children who are accepted by their parents and more resilient to trauma tend to have accelerated cortical thinning, a marker of brain development. In contrast, children exposed to domestic abuse tended to have slower brain microstructure development. The paper was published in psychiatry. As children grow, the cerebral cortex undergoes significant structural and physiological changes to support increasingly complex thoughts and behaviors. During early childhood**,**, the brain generates a large number of synaptic connections between neurons. This is a process known as synaptogenesis. This overproduction makes…

Recent research is writing research journal suggest that the written language of people with schizophrenia provides evidence about their unique symptom profile. This study shows that analyzing how these people summarize their stories can reveal distinct patterns in their writing, depending on whether they experience primarily positive or negative symptoms. These findings highlight the potential of using writing tasks to monitor clinical changes and tailor therapeutic interventions to patients with schizophrenia. Schizophrenia is a severe mental health condition that affects how you think, feel, and behave. This condition tends to fall into two main symptom categories. Positive symptoms include an…

Replacing animal fat with vegetable oil is associated with a lower risk of developing dementia in older adults. Based on a long-term analysis of dietary habits, researchers found that the specific types of fats a person consumes were correlated with later cognitive health. The study was published in The American Journal of Clinical Nutrition. Dementia is a progressive neurological disease characterized by a decline in memory, thinking, and reasoning abilities. The global number of people with dementia is expected to rise sharply in the coming decades, making identifying ways to prevent or delay the onset of dementia a top public…
