Attractive internuclear force drives the collective behavior of nuclear arrays in Drosophila embryos.

PLoS Computational Biology, 2021
The collective behavior of the nuclear array in Drosophila embryos during nuclear cycle (NC) 11 to NC14 is crucial in controlling cell size, establishing developmental patterns, and coordinating morphogenesis.

Repulsive black holes and higher-derivatives

Journal of High Energy Physics, 2022
In two-derivative theories of gravity coupled to matter, charged black holes are self-attractive at large distances, with the force vanishing at zero temperature.

The role of attractive forces in viscous liquids [PDF]

The Journal of Chemical Physics, 2011
We present evidence from computer simulation that the slowdown of relaxation of a standard Lennard-Jones glass-forming liquid and that of its reduction to a model with truncated pair potentials without attractive tails are quantitatively and qualitatively different in the viscous regime.

Opposites Attract: A Theorem about the Casimir Force [PDF]

Physical Review Letters, 2006
We consider the Casimir interaction between (non-magnetic) dielectric bodies or conductors. Our main result is a proof that the Casimir force between two bodies related by reflection is always attractive, independent of the exact form of the bodies or dielectric properties.
