As the warning label on every pack of cigarettes tells us, smoking is harmful. It’s the leading preventable cause of death, disease and disability. And yet, nearly 15 percent of adults in the United States still smoke.  “Most indicate they want to quit,” said Jeff Stein, an addiction researcher and assistant professor with Virginia Tech’s Fralin Biomedical Research Institute at VTC. “But knowing that smoking affects your health isn’t enough to motivate people. The future is just too abstract and often doesn’t feel real.” If ...

UNIVERSITY PARK, Pa. — Artificial intelligence (AI) is increasingly used to analyze medical images, materials data and scientific measurements, but many systems struggle when real-world data do not match ideal conditions. Measurements collected from different instruments, experiments or simulations often vary widely in resolution, noise and reliability. Traditional machine-learning models typically assume those differences are negligible — an assumption that can limit accuracy and trustworthiness. To address this issue, Penn State researchers have developed a new artificial intelligence framework with potential implications for fields ranging from Alzheimer’s disease ...

Boulder, Colo., USA: Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was walking through the Dadès Valley in the Central High Atlas Mountains of Morocco when she saw something that literally stopped her in her tracks. Martindale and her colleagues, including Stéphane Bodin of Aarhus University, were trekking through the rocky valley to study the ecology of the ancient reef systems that once sat below sea level there. To get to the reefs, they first had to traverse through layers and layers of turbidites—deposits made by thick submarine ...

BATON ROUGE, La. – Pennington Biomedical researchers recently investigated the systems of the body that regulate weight, exploring whether our bodies defend an established weight target or if our bodies operate within a broader range of tolerance before biological mechanisms are activated. The paper, titled “Body weight regulation models in humans: insights for testing their validity,” which was recently published in Nature Reviews Endocrinology, examined competing body weight regulation models and analyzed how energy intake and expenditure interact ...

Large language models (LLM) can generate treatment recommendations for straightforward cases of hepatocellular carcinoma (HCC) that align with clinical guidelines but fall short in more complex cases, according to a new study by Ji Won Han from The Catholic University of Korea and colleagues publishing January 13th in the open-access journal PLOS Medicine. Choosing the most appropriate treatment for patients with liver cancer is complicated. While international treatment guidelines provide recommendations, clinicians must tailor their treatment choice based on cancer stage and liver function as well as other factors such as comorbidities. To assess whether LLMs can provide treatment ...

In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth. Phil Huss of the University of Wisconsin-Madison, U.S.A., and colleagues present these findings January 13th in the open-access journal PLOS Biology. Interactions between phages—viruses that infect bacteria—and their hosts play an integral role in microbial ecosystems. Often described as being in an ...

(Santa Barbara, Calif.) — Clouds, smoke and fog may darken the skies, but sediment, algae blooms and organic matter can turn day into night on the seafloor. That’s why an international team of scientists have created the first framework to identify and compare these marine blackouts. The study, published in Communications Earth & Environment, introduces the concept of a marine darkwave: a short-term but intense episode of underwater darkness that can severely impact kelp forests, seagrass beds and other light-dependent ...

Dopamine in the brain influences movement, learning, motivation and sleep. In humans, problems with dopamine are linked to conditions like Parkinson’s disease, depression and sleep disorders. While scientists know a great deal about how dopamine works in the brain, they know less about how the body controls dopamine levels. Understanding this could help treat diseases where dopamine is disrupted. In a new study published in iScience, researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Institute at Texas Children’s Hospital (Duncan NRI) worked with the laboratory fruit fly to find new genes involved in regulating dopamine ...

A landmark international study that pooled brain scans and memory tests from thousands of adults has shed new light on how structural brain changes are tied to memory decline as people age. The findings — based on more than 10,000 MRI scans and over 13,000 memory assessments from 3,700 cognitively healthy adults across 13 studies — show that the connection between shrinking brain tissue and declining memory is nonlinear, stronger in older adults, and not solely driven by known Alzheimer’s-associated genes like ...

Many people are optimistic about ammonia’s potential as an energy source and carrier of hydrogen, and though large-scale adoption would require major changes to the way it is currently manufactured, ammonia does have a number of advantages. For one thing, ammonia is energy-dense and carbon-free. It is also already produced at scale and shipped around the world, primarily for use in fertilizer. Though current manufacturing processes give ammonia an enormous carbon footprint, cleaner ways to make ammonia do exist. A better understanding of how to guide the ammonia fuel industry’s continued development ...

A new study led by researchers at UTHealth Houston investigated both gene expression and regulation at single cell levels to reveal disruptions in gene function in three brain regions of patients with sporadic early onset Alzheimer’s disease. The findings were published in Science Advances. Only about 5% to 10% of patients with Alzheimer’s disease are younger than 65. Of those patients, 10% have mutations in the APP, PSEN1, and PSEN2 genes, which are associated with Alzheimer’s disease. The other 90% of these cases are classified as sporadic early onset Alzheimer’s, a rare and aggressive form of the ...

Increases to the minimum wage may do more than bolster household income, reduce inequality and enhance worker well-being: They may also help make pregnancies safer, according to new research from Rutgers University. A study published online ahead of the Fe in the American Journal of Preventive Medicine finds that state-level increases in the minimum wage are associated with lower rates of hypertensive disorders of pregnancy, a leading cause of maternal mortality in the United States. The study, led by Slawa Rokicki, an assistant professor at the Rutgers School of Public Health, ...
