Precede this with the name of your company or organization, e.g. Xacti.drives.science, and you have a superb main web address or campaign slogan that is direct, descriptive and positive. This would work well for science equipment or supply companies, scientific software, scientific publishers, etc. It is registered until July 8, 2018, and renews at standard .science rates. Why not make this useful domain expression yours today, and then put it to good use!
