Lining the shelves of American supermarkets are food products with chemicals linked to health concerns. To a great extent, the FDA allows food companies to determine for themselves whether their ingredients and additives are safe. Companies don't have to tell the FDA about those decisions, and they don't have to list all ingredients on [...]
The number of lives lost around the world due to infections that are resistant to the medications intended to treat them could increase nearly 70% by 2050, a new study projects, further showing the burden of theongoing superbug crisis. Cumulatively, from 2025 to 2050, the world could see more than 39 million deaths that [...]
Nanomaterials are no longer just small—they are becoming smart. Across fields like medicine, electronics, energy, and materials science, researchers are now programming nanomaterials to behave in intentional, responsive ways. These advanced materials are designed to detect specific stimuli, such as heat, pH changes, or light, and react with precise functions, like releasing a drug, [...]
Higher levels of micronanoplastics were found in carotid artery plaque, especially in people with stroke symptoms, suggesting a potential new risk factor. People with plaque buildup in the arteries of their neck have been found to carry higher concentrations of tiny plastic particles within those blood vessels compared to individuals with healthy arteries. This [...]
Researchers at the University of Minnesota have completed a first-in-human clinical trial testing a CRISPR/Cas9 gene-editing technique to help the immune system fight advanced gastrointestinal (GI) cancers. The results, recently published in The Lancet Oncology, show encouraging signs of the safety and potential effectiveness of the treatment. "Despite many advances in understanding the genomic drivers and other [...]
Graphic abstract of the development of VEDIC and VFIC systems for high efficiency intracellular protein delivery in vitro and in vivo. Credit: Nature Communications (2025). DOI: 10.1038/s41467-025-59377-y. https://www.nature.com/articles/s41467-025-59377-y Researchers at Karolinska Institutet have developed a technique that enables efficient delivery of therapeutic proteins and RNA to cells. The method, published in Nature Communications, shows promising results in animal studies [...]
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 [...]
