Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

The proton reactions in host metals like palladium, nickel, or titanium generate elements up to a proton number Z = 82 (lead), where the generation probability follows a kind of Boltzmann distribution. This is very similar to the standard abundance distribution of the elements in the universe for heavy elements. The analogy leads to a relation to the magic numbers of the nuclear shell model, to its alternative (more general) foundation on the Bagge series contrary to the spin model of Jensen and Goeppert-Mayer, and to new large magic numbers in agreement with Greiner et al.'s results on superheavy elements.
