Researchers have demonstrated a novel vaccine delivery method in an animal model, using dental floss to introduce the vaccine via the tissue between the teeth and gums. The testing found that the new technique stimulates the production of antibodies in mucosal surfaces, such as the lining of the nose and lungs. https://phys.org/news/2025-07-future-vaccines-dental-floss.html Bio & Medicine Mon, 28 Jul 2025 12:40:06 EDT news672924615 Chronic stress can lead to increased blood pressure and cardiovascular disease, decreased immune function, depression, and anxiety. Unfortunately, the tools we use to monitor stress are often imprecise or expensive, relying on self-reporting questionnaires and psychiatric evaluations. https://phys.org/news/2025-05-dental-floss-stress.html Biochemistry Mon, 26 May 2025 08:49:50 EDT news667468185 A shapeshifting robotic microswarm may one day act as a toothbrush, rinse, and dental floss in one. The technology, developed by a multidisciplinary team at the University of Pennsylvania, is poised to offer a new and automated way to perform the mundane but critical daily tasks of brushing and flossing. It's a system that could be particularly valuable for those who lack the manual dexterity to clean their teeth effectively themselves. https://phys.org/news/2022-07-shapeshifting-microrobots-floss-teeth.html Bio & Medicine Tue, 05 Jul 2022 17:09:21 EDT news576259647 Fungi, with the exception of shitake and certain other mushrooms, tend to be something we associate with moldy bread or dank-smelling mildew. But they really deserve more respect. Fungi have fantastic capabilities and can be grown, under certain circumstances, in almost any shape and be totally biodegradable. And, if this weren't enough, they might have the potential to replace plastics one day. The secret is in the mycelia. https://phys.org/news/2013-03-fungi-plastics.html Materials Science Tue, 12 Mar 2013 18:02:36 EDT news282330148
