Fermilab contributes to the local economy in more ways than most people realize, according to Fermilab business manager David Carlson. The lab most obviously contributes through employment and procurement, which Carlson called the lab's "near-term impact." It employs over 2,000 people (not including subcontractors). Employees earn a combined salary of $145 million, and they contribute to the local economy whenever they spend money in the towns near the lab: buying houses, cars, even groceries.
Regarding procurement, Carlson explained, "Federal government policy is to encourage businesses within certain socio-economic categories to grow and thrive, and because Universities Research Association, Inc. (URA) is a prime government contractor, we carry out those policies." Procurement funds in 2005 included over $48 million to small businesses and $13 million to woman-owned businesses. Over $60 million went to Illinois firms. Even more important may be the long-term economic impact, which hinges on
"We're constantly pushing industry to the edge of what they can do," Carlson added. "The superconducting niobium-titanium wire we requested for the Tevatron paved the way for the wire in the magnets in many of the world's MRI machines today."

Chicago Sun-Times, February 10, 2006: U.S. seeks bids on managing Fermilab, Argonne West suburban Fermilab, the world leader in subatomic physics, is about to get new management as it faces a critical crossroads. Since it began in 1967, Fermilab has been managed by a consortium of universities for the federal government, which pays the bills.
But now the U.S. Energy Department is putting out to bid the management contracts of Fermilab and other federal labs. |

Institute of Physics, February 10, 2006: Theorists claim dark energy does not exist Most cosmologists believe that the universe is dominated by "dark energy" - a mysterious form of energy that could explain why the universe is expanding and accelerating at the same time. Now, however, theoretical physicists have studied a new model of gravity that can, they claim, account for the acceleration of the universe without any need for dark energy. Their model relies instead on modifications to the way that gravity behaves at ultra-large cosmological distances (Phys. Rev. Lett. 96 041103). The acceleration of the universe is driven by something that has repulsive rather than attractive gravitational interactions. Although this so-called "dark energy" is thought to account for around two-thirds of the universe, no one knows what it is made of. Possible explanations for dark energy include a "cosmological constant" - first introduced by Einstein - or something known as quintessence. However, such explanations are plagued with theoretical and phenomenological problems and scientists would like to find an alternative to dark energy as the source of the universe's acceleration.
Olga Mena and José Santiago at Fermilab and Jochen Weller of University College London have now calculated that the acceleration of the universe can be explained without the need for dark energy. What they have done is to modify the laws of gravity in such a way that they look relatively unchanged at short distances but get modified only at distances on the order of the current size of the observable universe - the only place where the effects of the acceleration are apparent. At these distances the curvature of space is so small that the universe appears flat.
