A new review reveals how plant- and microbe-derived nanoparticles can power next-gen water disinfection, delivering cleaner, safer water without the environmental cost of traditional treatments. A recent review published in Nanomaterials highlights the potential of green-synthesized nanomaterials (GSNMs) in advancing safer and more sustainable water disinfection methods. The article explores how these materials are produced, how they act against [...]

Damage to the brainstem - the brain's 'control center' - is behind long-lasting physical and psychiatric effects of severe Covid-19 infection, a study suggests. Using ultra-high-resolution scanners that can see the living brain in fine detail, researchers from the Universities of Cambridge and Oxford were able to observe the damaging effects Covid-19 can have [...]

Researchers at National Jewish Health have shown that subtle increases in lung scarring, detected by an artificial intelligence-based tool on CT scans taken one year apart, are associated with disease progression and survival in patients with fibrotic interstitial lung disease. The findings, recently published in the American Journal of Respiratory and Critical Care Medicine, suggest that [...]

Researchers suggest that examining the inner workings of cells more closely could help physicians detect diseases earlier and more accurately match patients with effective therapies. Researchers at McGill University have created an artificial intelligence tool capable of uncovering disease markers that were previously hidden within individual cells. The study, published in Nature Communications, describes how this new system, called [...]

Mass General Brigham’s HPV-DeepSeek test enables much earlier cancer detection through a blood sample, creating a new opportunity for screening HPV-related head and neck cancers. Human papillomavirus (HPV) is responsible for about 70% of head and neck cancers in the United States, making it the most common type of cancer linked to the virus. Rates [...]

The symptoms come on quickly—acute fever, followed by debilitating joint pain that can last for months. Though rarely fatal, the chikungunya virus, a mosquito-borne illness, can be particularly severe for high-risk individuals, including newborns and older adults. While the virus is common in tropical and subtropical regions, including Asia, Africa and South America, public health officials have [...]

Summary: A groundbreaking study reveals how obesity may drive Alzheimer’s disease through tiny messengers called extracellular vesicles released from fat tissue. These vesicles carry lipids that alter how quickly amyloid-β plaques form, a hallmark of Alzheimer’s. Because they can cross the blood-brain barrier, they act as a direct communication line between body fat and the [...]

Scientists reveal that short-term ozone inhalation doesn’t just harm the lungs; it reshapes the microbes in your mouth, with men facing the greatest risks. Ozone is a toxic environmental pollutant with wide-ranging effects on the body. A new study in Environment & Health investigates the impact of ozone on the oral microbiome and lung function. Introduction Ozone is [...]

Even though many years have passed since the start of the COVID-19 pandemic, the effects of infection with SARS-CoV-2 are not completely understood. This is especially true for Long COVID, a chronic condition that can develop after COVID-19 that causes a variety of lasting symptoms. Among the most common and debilitating of these is [...]

Scientists have, for the first time, directly visualised the protein clusters in the brain believed to trigger Parkinson's disease, bringing them one step closer to potential treatments.  Parkinson's is a progressive incurable neurological disorder that affects the brain, but also the body more widely, and blights the lives of millions. Patients typically suffer progressive [...]
