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 [...]
Growing numbers of West Nile virus infection cases, fueled by climate change, are sparking fears among citizens and healthcare providers in Europe. A Clinical Insight in the European Journal of Internal Medicine, published by Elsevier, aims to raise awareness and equip medical professionals with the knowledge needed to recognize and manage this emerging disease to [...]
Researchers report a materials breakthrough enabling a new wave of nanodrug applications, from delivery to diagnostics and gene editing, with global impact. (Nanowerk News) An Australian research team has achieved an advanced materials breakthrough that opens the door to a new generation of nanodrug applications. From drug delivery, to diagnostics, to gene editing and [...]
Imagine tossing aside your reading glasses and regaining crisp, youthful vision with just a few drops a day. New research suggests that specially formulated eye drops can significantly improve near vision in people with presbyopia — age-related difficulty focusing on close objects. Patients reported sharper sight within an hour, sustained improvements for up to [...]
Researchers from Trinity College Dublin have discovered that electrically stimulating 'macrophages' – one of the immune system's key players – can 'reprogramme' them in such a way to reduce inflammation and encourage faster, more effective healing in disease and injury. This breakthrough uncovers a potentially powerful new therapeutic option, with further work ongoing to [...]
When Alex Sprackland caught Covid-19 in March 2020, he thought he’d be back to normal in no time. Yet, five years on, the 34-year-old still grapples with the severe, life-limiting effects of the infection. ‘I was diagnosed with long Covid seven months after my initial illness – my life has never been the same,’ Alex, from [...]
Researchers at Trinity Biomedical Sciences Institute (TBSI) have found that nanoplastics, which are even smaller than microplastics, impair energy metabolism in brain cells. The results were reported in the Journal of Hazardous Materials: Plastics. In addition to providing fresh insight into learning and memory problems, their discoveries may help better understand neurodegenerative diseases, which are characterized by [...]
