A new home

Welcome to my all-new BBC page. Here you'll be able to read my comments on science and the environment, view tweets and listen to my radio features for the Today programme.

It's an exciting change which I hope will make it easier for you to follow me and engage with BBC stories, whether in text, audio or video.

As ever, I welcome your feedback, especially about this the new format. And don't forget to add this page to your bookmarks and RSS feed.
