Effect on the body of zero G | Measuring mental health services | Genetic analysis and cerebral palsy

With humans set to spend more time in spacer, one of the physical things to overcome will be gravity, and it's very important for how our bodies work. We hear frequent stories of mental health issues, but there is more investment in services, so are services effective or overwhelmed? An estimated 34,000 people in Australia have cerebral palsy. The cause can be a mystery but looking at a child's genes may supply information for parents and treatment teams.  Hosts: Dr Norman Swan Tegan Taylor
