Dark Energy in the Lab?

For many years astronomers have known about dark matter - matter that is out there but we can't see it - because of the rotation of galaxies. Although more trendy people might say it is due to MOND (fiddling about with gravity). In the last few years, observations of the Cosmic Microwave Background (CMB) by instruments such as Boomerang, MAXIMA and WMAP, have shown that dark matter makes up less than 25% of the Universe. The rest - about three quarters - is in the form of dark energy which we have even less of a clue about.

The Institute of Physic's PhysicsWeb reports on an astro-ph paper by Beck and Mackey.They basically say that dark energy could be related to the energy of the vacuum and suggest that this could be tested in the lab in the future.
