From the Editor: Changes at LiveScience

COLUMNISTS: We've recently added two new columnists to our stable of writers who get beyond the news and events of the day to debunk myths and explore more deeply how science, medicine, culture, history and the media all impact and relate to everyday life. You'll find them all on the home page today.

VIDEO NAVIGATION: During the past four years, our video team has produced and compiled a rich array of video ranging from short clips fresh out of the world's laboratories to longer news and feature presentations. These now have a home on our home page and in the new video section.

TOPIC PAGES: Beyond our basic sections (e.g. Space, Animals, Environment and so on), there is a wealth of news, features, imagery and video on topics as varied as dinosaurs, lousy weather and the science of sex. We've begun to sort and collect these stories into "topic pages," and soon we'll post a complete list of all of them.

POLLS: LiveScience is about science, but it is for you. As always, we invite your participation. The Community is becoming more lively each week, with insightful and often highly opinionated comments helping to flesh out the true meaning and impact of everything we cover. That in mind, polls are now being included with select stories, so that even those of you who don't wish to speak out by commenting can have a voice on complex and often controversial topics. (Oh, and you can find all of our stories that include polls, or are about polls and surveys, on this topic page.)

We've got more additions and improvements planned for 2009, so please let us know how you think we're doing. You can comment below, or click on any of our bylines at the tops of stories to email us directly. — RRB
