AA << show that the axial magma chamber inflates/deflates in response to tidal stresses, producing Coulomb stresses on the faults that are opposite in sign to those produced by the tides. When the magma chamber’s bulk modulus is sufficiently low, the phase of tidal triggering is inverted. >>

<< Charged polymers are ubiquitous in biological systems because electrostatic interactions can drive complicated structure formation and respond to environmental parameters such as ionic strength and pH.  In these systems, function emerges from sophisticated molecular design; for example, intrinsically disordered proteins leverage specific sequences of monomeric charges to control the formation and function of intracellular compartments known as membraneless organelles. >>

<< The original article published in Nature stated that the galaxy (NGC1052-DF2) is at a distance of some 64 million light years from the Earth. However, this new research has revealed that the real distance is much less, around 42 million light years. (..) Thanks to these new results, the parameters of the galaxy inferred from its distance have become "normal," and fit the observed trends traced by galaxies with similar characteristics. >>
