How a conductive form of ice is formed at several thousand degrees and millions of times atmospheric pressure. Not all ice is the same. The solid form of water comes in more than a dozen different – sometimes more, sometimes less crystalline – structures, depending on the conditions of pressure and temperature in the environment. Superionic ice is a special crystalline form, half solid, half liquid — and electrically conductive. Its existence has been predicted on the basis of various models and has already been observed on several occasions under — very extreme — laboratory conditions...

Strike-slip faulting, the type of motion common to California’s well-known San Andreas Fault, was reported recently to possibly occur on Titan, Saturn’s largest moon. New research, led by planetary scientists from the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology (SOEST), suggests this tectonic motion may be active on Titan, deforming the icy surface.

On multiple ocean worlds, for example Jupiter’s Europa and Saturn’s Enceladus, expressions of strike-slip faulting are well documented...

The latest research has implications for understanding sensory disorders and building better prosthetics and robots that can fine-tune their movements based on what they touch. Researchers have discovered how neurons in a small area of the mammalian brain help filter distracting or disruptive signals — specifically from the hands — to coordinate dexterous movements. Their results may hold lessons in how the brain filters other sensory information as well.
