Nanomaterials are materials with at least one dimension smaller than 100 nanometres (about 100,000 times thinner than a human hair). Because of their tiny size, they have unique properties that can be useful in many industries.1 However, without proper regulation, nanomaterials could pose risks to human health and the environment. A clear and consistent [...]
Virginia Tech researchers discovered six new rodent carriers of hantavirus and identified U.S. hotspots, highlighting the virus’s adaptability and the impact of climate and ecology on its spread. Hantavirus recently drew public attention following reports that it was the cause of death for Betsy Arakawa, wife of actor Gene Hackman. Despite the headlines, the virus [...]
Researchers have estimated approximately 8% of Americas have ever experienced long COVID, or lasting symptoms, following an acute COVID-19 infection. Now two recent international studies suggest that the percentage is much higher among healthcare workers and dental professionals. 40% prevalence in health workers globally In the first study, published in BMJ Public Health, authors conducted a [...]
Melting Arctic ice increases human and animal interactions, raising the risk of infectious disease spread. Researchers urge early intervention and surveillance. Climate change is opening new pathways for the spread of infectious diseases such as brucellosis, tularemia, and E. coli in the Arctic, according to a broad international team of scientists with expertise in [...]
Researchers at Cold Spring Harbor Laboratory have found that blocking the FGFR2 and EGFR genes can stop early-stage pancreatic cancer from progressing, offering a promising path toward prevention. Pancreatic cancer is expected to become the second-leading cause of cancer-related deaths by 2030. One of the main challenges is that it’s often diagnosed at an [...]
Blocking the PROX1 protein allowed KAIST researchers to regenerate damaged retinas and restore vision in mice. Vision is one of the most important human senses, yet more than 300 million people around the world are at risk of losing it due to various retinal diseases. Although recent treatments have helped slow the progression of these conditions, [...]
Researchers from Tokyo Metropolitan University have found that the motion of unlabeled cells can be used to tell whether they are cancerous or healthy. They observed malignant fibrosarcoma cells and healthy fibroblasts on a dish and found that tracking and analysis of their paths can be used to [...]
After more than five decades of mystery, scientists have finally unveiled the detailed structure and function of a long-theorized molecular machine in our mitochondria — the mitochondrial pyruvate carrier. This microscopic gatekeeper controls how cells fuel themselves by transporting pyruvate, a key energy source, across mitochondrial membranes. Now visualized using cryo-electron microscopy, the carrier’s [...]
Researchers have uncovered the 3D structure of RBP3, a key protein in vision, revealing how it transports retinoids and fatty acids and how its dysfunction may lead to retinal diseases. Proteins play a critical role in the human body, acting as essential structural and functional components of cells, tissues, and organs. They are involved [...]
Nanoplastics are typically defined as plastic particles smaller than 1000 nanometers. These particles are increasingly being detected in human tissues: they can bypass biological barriers, accumulate in organs, and may influence health in ways researchers are only beginning to understand.1 This article outlines five key evidence-based findings on how nanoplastics interact with the human [...]
