What does it feel like to be part of a study which might have its funding cut? Marty Reiswig has a rare genetic mutation that means he will get Alzheimer’s disease in his forties or fifties. For fifteen years he’s been part of medical studies into his condition, but now, with the NIH announcing funding cuts, he’s worried the studies will stop.

Also on the program, would you do CPR on another bystander? A new study finds that speed of response – not how trained you are – is what’s important. So how can we get more people doing this live-saving measure? And MRI imaging indicates that babies might actually be encoding memories. So why can’t we remember what it was like to be that young?
