University of Pittsburgh School of Medicine scientists are one step closer to developing a brain-computer interface, or BCI, that allows people with tetraplegia to restore their lost sense of touch. While exploring a digitally represented object through their artificially created sense of touch, users described the warm fur of a purring cat, the smooth [...]
Scientists have long known that bacteriophages, viruses that infect bacteria, live in our gut, but exactly what they do has remained elusive. Researchers developed a clever mouse model that can temporarily eliminate these phages without harming the bacteria, using a UTI treatment ingredient called acriflavine. Their experiments showed that without phages, gut bacteria become [...]
Background Wound healing is a complex physiological process that can be compromised by infection and impaired tissue regeneration. Conventional dressings, typically made from natural fibers such as cotton or linen, offer limited functionality. Nanofiber scaffolds, particularly those based on biocompatible polymers like PLA, provide high surface area and porosity, making them suitable for controlled [...]
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 [...]
