"Scientists use gravity lensing measurements to determine mass of galaxy clusters. Anja von der Linden, an astrophysicist at the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University in California, is using the Subaru telescope and the Canada-France-Hawaii telescope, both on Mauna Kea in Hawaii. The results are 40% higher than the measurements done by the Planck collaboration.

I guess there goes Douglas Adams' theory that the missing mass was in the packing material of the scientists' equipment."

  All very true but there's a reason that, despite a lack of direct evidence, "dark matter" is usually considered part of a incomplete theory rather then just a placeholder. Alternate theories like MoND http://en.wikipedia.org/wiki/Modified_Newtonian_Dy namics [wikipedia.org] can't explain nearly as much, as well, as dark matter.
