IANAL... The reason you can get a huge settlement in the talc case but not in this case is because people are purchasing the talc and so it is a product liability issue.
In the research case people are basing their care and procedures off another person's research. There is no direct payment from the person receiving the care to the researcher and so it is difficult to draw a direct line from Person A says X to Person B gets injured.
