How hydrogels could repair intestinal injuries

Hydrogels have already shown promise creating soft robotics and regrowing skull bones. New research suggests the water-based material could also help deliver stem cell treatment to repair damages caused by gastrointestinal diseases. Hydrogels have been permeating medtech recently – with researcheres using them for tasks as varied as gluing detached retinas back together to stopping bleeding. Now,

8 ways 3D printing is making surgery remarkable

3D printing is already making a difference in healthcare: It enables models of organs to train surgeons and educate patients –and improve surgical outcomes.

Here’s how vagus nerve stimulation is getting better

Georgia Institute of Technology researchers have reported success targeting vagus nerve stimulation – providing hope for people with a host of inflammatory diseases including rheumatoid arthritis, irritable bowel syndrome and Crohn’s disease. Researchers implanted a pacemaker-like device into rats and showed that it could electrically stimulate the vagus nerve while simultaneously preventing unwanted nerve activity.
