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.

Experimental data showing generation of 4He from a Pd sheet-D2 gas system observed by E. Botta et al. are analyzed by the trapped neutron catalyzed fusion (TNCF) model. The proposed mechanism of 4He generation is not the direct d-d reaction but the reactions between the trapped neutron and a Pd isotope, n-46APd reactions, with a supplemental assumption, decrease of threshold energies for (n,) reactions of 46APd in solids. The arbitrary parameter nn, the density of the trapped neutron, of the model is determined to be ~1012 cm-3, which is consistent with values determined in analyses of data in various events in the cold fusion phenomenon.
