Hi all, and welcome! On this site, devoted to sharing the excitement and meaning of science, you’ll find a blog (posts begin below) and reference articles (accessible from the menus above.) The site is being upgraded, so you’ll see some ongoing changes; if you notice technical problems, please let me know. Thanks, and enjoy!
Don’t forget to leave (polite) comments, and keep an eye out for days when I take direct questions from readers. Oh, and for the moment you can follow me on Twitter and Facebook.
