Magnetically-directed nanoparticles could help heal broken bones

By - November 24, 2014 1 Picture
When a bone is severely broken in the human body, or a bone-fused prosthesis is implanted, a bone graft is also often required to ensure a solid mechanical repair. However, a graft that removes bone from another area of the body can be a painful and invasive procedure, and the mechanical stimulation required for continued bone regeneration in post-operative therapy becomes problematic if a patient is severely immobilized. To address these problems, researchers have discovered that coating magnetic nanoparticles with proteins and then directing them magnetically to the site of the injury can help stimulate stem cells to regenerate bone.

Swearing proven to have a 'pain-lessening effect'

By - July 27, 2009 1 Picture
Swearing has been around for centuries and is an almost universal human linguistic phenomenon. Now researchers have determined that swearing can have a ‘pain-lessening effect.’ Swearing taps into emotional brain centers and appears to arise in the right brain, whereas most language production occurs in the left cerebral hemisphere of the brain. The research shows one potential reason why swearing developed and why it persists. Read More
