SciTechDaily offers the best intelligent, informed science and technology coverage and analysis you can find on a daily basis, sourcing a huge range of great writers and excellent research institutes. It was founded in 1998 by Vicki Hyde, a friend of Denis Dutton (of Arts & Letters Daily fame) and was essentially a sister site to ALDaily.com. The idea was to link to the most thought-provoking, well researched online items in the world of science and technology. (Originally, this site was known as SciTech Daily Review, but it was simplified to SciTechDaily in 2011. The address has always remained SciTechDaily.com.)
