Spinal cord injury research triggering an immune system response. Animal studies with injection of bone marrow stem cells have shown improvement in motor function; however not so in a human trial a year post-injury. More trials are underway. Adipose and umbilical tissue stem cells need further study before human trials can be performed, but two Korean studies were begun to investigate adipose cells in SCI patients. Transplantation of tissues such as olfactory ensheathing cells from the olfactory bulbs has been shown to produce beneficial effects in spinal cord injured rats. Trials have also begun to show success when olfactory ensheathing cells are transplanted into
Collaborative human interpreter Lenssen's blog . Collaborative human interpreter The collaborative human interpreter (CHI) is a proposed software interface for human-based computation (first proposed as a programming language on the blog Google Blogoscoped, but implementable via an API in virtually any programming language) specially designed for collecting and making use of human intelligence in a computer program. One typical usage is implementing impossible-to-automate functions. For example, it is currently difficult for a computer to differentiate between images of men, women and non-humans. However, this is easy for people. A programmer using CHI could write a code fragment along these lines: Code for the
