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.

This paper describes a possibility to control of laser ablation using material functionality. As an example, a remarkable difference is shown in the laser ablation of a polystyrene film coated with a photovoltaic perylene/phthalocyanine bilayer when compared with a bare polystyrene film after irradiation at an intensity range of 109 ∼ 1010W/cm2 (λ=1064 nm, 1.1-ns FWHM). Without the bilayer coating, the laser pulse formed spiky structures in the polystyrene film as self-focusing traces of the laser pulse, while for the coated film, the uniform surface ablation trace without the spiky interior structures was observed. The phenomena in the presence of the organic photovoltaic coating material agree with the required ablation to achieve high-density compression of the fuel capsule for inertial fusion energy.
