As well as all the extra features, Dr Noemi Eiser concludes her feature on COPD, Mollie Jackson answers your questions on oxygen concentrators and stomach problems, Ian Jarrold looks back at the most notable research grants of the last 25 years and Danielle Smreczak brings you another stretching exercise to do at home.
