[…] In the body, the shapes of many collagen-containing tissues, including corneas, are held in place by attractions of oppositely charged components. These tissues contain a lot of water, so applying an electric potential to them lowers the tissue’s pH, making it more acidic. By altering the pH, the rigid attractions within the tissue are Read more about Forget LASIK: Safer, cheaper vision correction could be coming soon[…]

An experimental mRNA vaccine boosted the tumor-fighting effects of immunotherapy in a mouse-model study, bringing researchers one step closer to their goal of developing a universal vaccine to “wake up” the immune system against cancer. Published recently in Nature Biomedical Engineering, the University of Florida study showed that like a one-two punch, pairing the test vaccine Read more about A new mRNA cancer vaccine just wiped out tumors in mice[…]

Researchers at Columbia Engineering have built a cancer therapy that makes bacteria and viruses work as a team. In a study published recently in Nature Biomedical Engineering, the Synthetic Biological Systems Lab shows how their system hides a virus inside a tumor-seeking bacterium, smuggles it past the immune system, and unleashes it inside cancerous tumors. The Read more about Trojan horse bacteria sneak cancer-killing viruses into tumors[…]

Nearly a quarter of people over the age of 40 experience painful osteoarthritis, making it a leading cause of disability in adults. Osteoarthritis degrades joint-cushioning cartilage, and there is currently no way of reversing this damage: the only option is to manage pain with medication, and eventually, joint replacement. Researchers from the University of Utah, Read more about One small walking adjustment could delay knee surgery for years[…]

[…] on the cutting edge of this field, neuroscientists have more recently developed brain implants that can turn neural signals directly into whole words. These brain-computer interfaces (BCIs) largely require users to physically attempt to speak, however—and that can be a slow and tiring process. But now a new development in neural prosthetics changes that, Read more about New Brain Device Is First to Read Out Inner Speech[…]

Keratin-based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin’s structural adaptability and mineral ions-binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a promising, sustainable platform for functional enamel regeneration, offering a clinically translatable approach for repairing demineralized dental enamel Read more about Hair based toothpased could fix your tooth enamel[…]
