    This is The Naked Scientists. Hello. Welcome to this week's Naked Scientists podcast, the program that brings you the biggest breakthroughs and talks to the major movers and shakers in the worlds of science, technology, and medicine. With me, Chris Smith. And coming up, can intestinal bacteria lead to Parkinson's disease? A new study shows consistent changes in the microbiome even ahead of the diagnosis. Also, two bouts of diarrhea and a cold every month. Infectious diseases doctors highlight the true cost of parenthood, and a breakthrough that might make lasers orders of magnitude more powerful. But what will we do with them? [outro music] Scientists in London have found that changes to microbes in the gut can identify people who are at greater risk of developing Parkinson's disease. The study, which has been published in Nature Medicine, profiled the microbiomes of people with Parkinson's, people at high genetic risk of developing Parkinson's, and members of the general public with some of the early signs that they might be developing the disease. It suggests that changes to gut microbes might cause or at least contribute to the disease becoming clinically manifest, possibly by altering
