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 [...]
Researchers have identified over 4,000 nanomedical clinical trials in progress now, highlighting rapid growth in the field and the need for a standardized lexicon to support clinical translation and collaboration. Nanotechnology is the science of materials at the nanoscale, where matter behaves differently than it does at larger scales. The unique properties at this size [...]
A new approach for cancer treatment involves the use of microalgal-derived nanoparticles. A recent review in Frontiers in Bioengineering and Biotechnology examines their potential as a sustainable and biocompatible solution. Promise and Limitations Nanoparticles (NPs), defined as particles of between one and 100 nanometers, possess unique physical, chemical, and biological properties that are not observed in bulk [...]
US Scenario Modeling Hub, a collaborative modeling effort of 17 academic research institutions, reports a universal COVID-19 vaccination recommendation could avert thousands more US hospitalizations and deaths than a high-risk-only strategy. COVID-19 remains a substantial current public health concern in the US, with higher in-hospital mortality than seasonal influenza during fall-winter 2023–2024. The Advisory [...]
