Regular exercise may benefit your heart in ways that scientists are only beginning to understand. In addition to improving cardiovascular health, new research suggests that moderate aerobic exercise reshapes the nerves that regulate the heart. The findings could ultimately help doctors develop more precise treatments for common heart conditions. Researchers at the University of Bristol, UK, have discovered for the first time that regular aerobic training causes different changes in the nerves that control the heart on the left and right sides of the body. This study autonomic neuroscienceone day revealed significant laterality differences that may improve treatment strategies for…

New research from Yale School of Medicine (YSM) suggests that the eye processes visual information in a much more intimate way than scientists thought. The discovery challenges long-held ideas about how visual signals travel across the retina and may help explain how we detect faint objects and see in the dark. Our visual system quickly analyzes various features of a scene, such as color, contrast, movement, and shape. This process, known as parallel visual processing, allows the brain to interpret complex images almost instantly by sending different types of information along separate paths. Researchers have long believed that these pathways…

Plastic debris in the ocean. Image credit: Wiki Commons. In the middle of the North Pacific Ocean, thousands of miles from the nearest continent, sea anemones, hydroroids, crustaceans and other coastal animals live off discarded fishing nets, plastic boxes and bottles. Plastic and marine life usually make a scary combination. But researchers have documented something more complicated here. These animals breed and form communities with organisms that have evolved to live in the open ocean. The Great Pacific Garbage Patch has provided the durable surface needed for fortuitous ecosystems to take root beyond any coastline on Earth, according to a…

President Donald Trump signed an order Monday to reduce the size of two huge national monuments in Utah, a move likely to reignite conflict with conservationists and public lands advocates. “Fairness has been restored,” Trump said at a signing ceremony in the Oval Office, watched by Utah’s congressional delegation and Republican Gov. Spencer Cox. The move mirrors monument cuts made by President Trump during his first term in office and later reversed by former President Joe Biden. But the order signed Monday would cut even more land from protected monuments in the Utah desert. In 2017, President Trump reduced the…

A recent small study analyzes how the hallucinogen LSD reshapes brain activity. The study shows that the substance promotes widespread neural synchronization while blurring the boundaries between sensory perception and abstract thinking. Through computer modeling and brain scans, researchers found that LSD can alter the balance of excitation and inhibition in certain brain circuits, potentially disengaging the mind from deep-seated patterns. The research results were published in PLOS Computational Biology. Psychedelics are making a comeback in psychiatric research. Clinical trials suggest these substances may help treat conditions such as depression, anxiety, and addiction. Mental health disorders often involve rigid and…

A new study by researchers at LSU’s Pennington Biomedical Research Center, FMOL Health | Our Lady of the Lake Regional Medical Center and Metamol Institute, demonstrates that metabolic and bariatric surgery can be safely and effectively delivered to adolescents and young adults with severe obesity, showing promise for weight loss and improvements in obesity-related health outcomes. Published in bariatric surgery”Metabolic and Bariatric Surgery Outcomes in South Louisiana Adolescents and Young Adults” examined the outcomes of 76 patients ages 10 to 25 who underwent bariatric surgery between January 2020 and March 2025 through the Louisiana-based Metamor Institute Bariatric Surgery Program. Researchers…

Like other teens, many teens on the autism spectrum are looking to improve their social skills. They want new friends, fun with people with similar interests, and even romantic relationships. Adolescence is a moment of opportunity for these children. They want to build friendships. ” Dr. Daniel Abrams, Clinical Associate Professor of Psychiatry and Behavioral Sciences, Stanford University However, it is difficult for autistic teens to spread their social wings. A new study led by Stanford Medicine was published on July 13th. Proceedings of the National Academy of Sciencessheds light on key factors in how the brains of…

A study examining the personality traits of three major language models and their relationship to cooperativeness found that agreeableness was a key factor promoting cooperation. Other personality traits had limited effects. The paper is scientific report. Large-scale language models (LLMs) are artificial intelligence systems trained on very large collections of text to predict and generate language. These models can summarize, translate, answer questions, write code, and generate various types of text. Their outputs depend on training data, system instructions, user prompts, and the context of the conversation. In recent years, more companies and individuals have started using LLM as a…

Xanthan gum can be found almost everywhere. This food additive has thickening, stabilizing and gelling properties and is one of the most widely used additives in the food industry to adjust the consistency of ice cream, yogurt, cakes, sauces and gluten-free pasta. It is also used to prepare drinks for people with dysphagia or difficulty swallowing. However, a study conducted at Brazil’s Federal University of São Paulo (UNIFESP) has raised an important red flag by demonstrating that in experimental models, chronic intake of xanthan gum causes inflammation in the colon, induces changes in the gut microbiome, and leads to loss…

Chemists at the University of Houston are using breakthrough imaging techniques to reveal how copper imbalances in the body contribute to neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, and ALS. Although the root causes of these incurable diseases remain largely unknown and existing drugs only manage symptoms, researchers have long linked copper imbalances within neurons to severe neurological disorders. Tai Yen Chen, an associate professor of chemistry at the University of California, hopes to pinpoint malfunctioning cellular pathways, providing the foundational knowledge needed to develop future treatments and guide therapeutic strategies. Over the past decade, Chen’s lab has secured…
