But not by me. I've just come across another rather good website, 'The naked scientists': covers all the sciences, with podcasts, articles, science stories, experiments you can do at home (I want to try the chip packet fireworks some time) & question & discussion pages. I thought you might be interested in this one: RNA interference explained: a concise. interesting explanation of what RNA interference is, its significance, & how we can apply this knowledge.
This is a site I'll be dipping into on a regular basis :-)
