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 [...]
A new study from the Hebrew University of Jerusalem published in the Proceedings of the National Academy of Sciences sheds light on one of life's greatest mysteries: why biology is based on a very specific set of amino acids, and in particular, why nature selected alpha amino acids as the foundation for proteins. The research, led [...]
To explore possible treatments for various diseases, either animal models or human cell cultures are usually used first; however, animal models do not always mimic human diseases well, and cultures are far removed from tissue complexity. Advances in 3D printing, together with knowledge of biomaterials, are making it possible to recreate complex 3D [...]
Researchers discovered that people who don’t drink enough water react with sharper cortisol spikes during stressful events, explaining why poor hydration is tied to long-term health risks. A recent study in the Journal of Applied Physiology examined the impact of hydration status and habitual fluid intake on saliva cortisol reactivity to psychosocial stress. Suboptimal hydration and [...]
