... Because of the low conductivity, the magnetic coupling is weak and depends critically on density, temperature, ionisation rate and charged species. ... Implications When the Hall regime dominates near the midplane and ambipolar diffusion is dominant closer to the surface, a thicker layer of the disc is unstable to MRI perturbations and modes grow faster than under the ambipolar diffusion approximation. ... Right panel: For weak coupling, Hall limit perturbations grow until vA/cs ~ 2.9. ...

These close-up images, taken by an electron microscope, reveal tiny one-cell organisms called halophiles and methanogens. In a two-year laboratory study, scientists subjected these organisms to increasingly lower temperatures to determine the coldest temperatures at which the microbes could survive and reproduce. The study shows the microbes could survive at below-freezing temperatures and are within the temperature range on present-day Mars. ... Maryland Astrobiology Consortium/NASA/STScI ...
