Since its launch in 2004, LiveScience has aimed to be the most comprehensive, reliable and engaging source of science news. With renewed commitment, we've been investing heavily in recent months to improve the quantity and quality of our coverage.

And today we've cleaned up the site's design to better showcase this content.

Over the past year, we hired additional reporters and support staff and expanded our coverage of science news more than threefold. In 2010, as part of our growing TechMediaNetwork, we launched several sites whose content feeds into LiveScience: OurAmazingPlanet, MyHealthNewsDaily, TechNewsDaily and Life's Little Mysteries. Another sister site, SPACE.com, continues to provide most of LiveScience's astronomy coverage.

The team behind all these sites works together in our Manhattan newsroom, coordinating breaking news coverage and in-depth features on an extensive range of science, health and technology topics.

In the new design, you'll find articles from each of our major sections on the homepage, where you'll also find direct access to our image galleries, countdowns and infographics. And we've introduced two new features: Image of the Day and Wallpapers.

Feel free to reach out to us directly — let us know how we're doing now and in the future:
