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.

Heat transfer to liquid lithium in the presence of a transverse magnetic field and a gravity field was analyzed in a square cross-section duct. The duct had conducting vanadium walls. Magnetohydrodynamic equations in three dimensions in the Cartesian coordinate system were solved. First, the Nusselt number was calculated with no magnetic field and a gravity field. Second, the Nusselt number was calculated for the case of a transverse magnetic field acting on the fluid. Third, the Nusselt number was calculated for the case of a transverse magnetic field and a gravity field acting on the fluid. Only one face of the channel was heated. It was found that the Nusselt number is not sensitive to application of a gravity field and is sensitive to application of a transverse magnetic field and it decreases when a transverse magnetic field is applied. It is observed that when the intensity of the transverse magnetic field reaches 0.11 T, further reduction in the value of the Nusselt number almost stops.
