A new non-hormonal drug has been approved to treat menopausal hot flushes. It works by regulating the body's cooling signals and is now available on the NHS in England for those who cannot use hormone replacement therapy.

Before delving into the evidence with resident GP Dr Margaret McCartney, James finds out what it feels like to have a hot flush.

Also this week, James chats to Dr Manjula Meda, a microbiologist who is spearheading a radical new project. She has found that water systems in hospitals may be a breeding ground for antimicrobial resistance, and is tackling this by removing the sinks from wards. Is it effective and safe?

Finally, we all do it, but we don't like discussing it... Farting. James speaks to the University of Maryland's Professor Brantley Hall, who has developed a 'fart detector' that can measure emissions to get a better understanding of gut health. And James gets the chance to attach one to his pants for three days. For science, of course.
