There are widely publicized videos of plastic pollution trapping and harming some of our most beloved coastal creatures. What is less well known is the hidden but far-reaching impact of this sinking debris. A new study shows for the first time that plastic pollution is actively accumulating in the world’s most remote and extreme ecosystems: deep-sea hydrothermal vents. Researchers found that more than 90% of deep-sea snails and mussels living in vents more than 2,000 meters (6,600 feet) below the ocean’s surface are contaminated with microplastics. Much of this contamination comes from polymers such as polystyrene, which are widely used…

Published in Nicotine and tobacco researchThis study analyzed repeated cross-sectional survey data from 9,996 participants aged 16 years and older who reported current smoking. They found that while most smokers (76.9%) reported purchasing cigarettes only from legal sources, in 2025 23.1% reported purchasing cigarettes from an illegal source at least once in the past six months, up from 12.2% in 2023. Our findings suggest that more smokers are turning to illicit tobacco sources compared to 2023. This may partly reflect the economic pressures many have faced in recent years as people look for ways to reduce the cost…

Recent research published in Affective Disorders Journal Studies suggest that adults with attention-deficit/hyperactivity disorder and who struggle with emotional regulation are more likely to experience symptoms of insomnia. The findings provide evidence that lack of access to effective emotional coping strategies plays a major role in these sleep disorders, especially among young adults. This highlights the importance of addressing mental health when treating sleep problems in ADHD patients. Attention-deficit/hyperactivity disorder, commonly known as ADHD, is a condition characterized by differences in attention, concentration, and behavior. Adults with this condition often experience difficulty regulating their emotions in daily life. This means…

An international team led by Hiroshima University researchers has developed a new method to detect subtle early changes in collagen in human skin, before any visible signs of damage appear. This study ACS nano July 16, 2026 It has been revealed that the molecular organization and supramolecular chirality, or structural handedness, of dermal collagen breaks down before the visible fiber network actually thins or fragments. Collagen is a hierarchical substance that forms a highly organized network that supports the structure and mechanical strength of the skin. Traditional imaging techniques can easily identify visible degradation, such as fiber thinning or loss…

Astronomers have found strong evidence that TOI-5882, a sun-like star about 1,300 light-years from Earth, may have devoured one of its own planets. A research team led by University of Michigan astronomer Brooke Cotten has discovered important clues to the star’s chemical composition. TOI-5882 contains far more lithium than researchers typically expect to find in stars of this type. “You’re what you eat, right?” said Cotten, a graduate student researcher in UM’s astronomy department and lead author of the new report. astrophysical journal. “We know that planetary material contains much more lithium than stars. So when a star eats a…

Cambridge researchers have shown how commonly used sweeteners slow the growth of certain gut bacteria. One sweetener in particular, isosteviol, when combined with the antidepressant duloxetine, can significantly impair two important gut bacteria involved in regulating blood sugar levels and gut health, and can affect the body’s immune response. Scientists say more research is needed to understand the actual health effects of this laboratory study. This laboratory study is one of the first to evaluate the direct effects of sweeteners on gut bacteria, particularly when combined with other substances. Sweeteners are widely used in a variety of foods and beverages,…

case report of Chinese Neurosurgical Journal describe a new salvage surgical approach for refractory multiple sclerosis-associated trigeminal neuralgia. In one patient who failed medical, percutaneous, and radiosurgical treatments, a procedure combining internal neurolysis (neurocombing) with targeted glycerol delivery to the proximal trigeminal nerve was performed. Patients experienced immediate pain relief, with no recurrence for 43 months on the treated side, preserved sensation, and reduced drug use. Multiple sclerosis-related trigeminal neuralgia (MS-TN) is one of the most painful neurological complications experienced by people with multiple sclerosis. Compared to classic trigeminal neuralgia, MS-TN is often more difficult to treat, more likely to…

Migraines, digestive problems, anxiety, and depression can be part of endometriosis, but they are often interpreted as separate diseases. In a study led by the Institut Saint-Pau (IR Saint-Pau), human reproduction identified different symptom patterns in more than 22,000 women, reinforcing the idea that the disease extends far beyond traditional gynecological symptoms. For many years, endometriosis has been classified primarily based on the location and extent of lesions observed during surgery and imaging tests. However, these systems only partially describe patients’ real-life experiences and do not adequately account for the large variation in symptoms associated with the disease. Additionally, a…

The World Health Organization (WHO) today published updated guidelines on reducing the risk of cognitive decline and dementia, providing countries with evidence-based recommendations to help prevent or delay the onset of dementia across the life course. Dementia is a condition caused by a brain disease that affects memory, thinking, and functional ability. More than 57 million people worldwide have dementia, and nearly 10 million new cases are diagnosed each year. Alzheimer’s disease is the most common form of dementia and is estimated to account for 60-70% of cases. There is no cure for dementia, but up to 45% of the…
