Welcome to Part 2 of ‘How to Fix the Art World.’ If you are just now tuning in, here’s a link to  Part 1 , and here’s a little background: Back in August my staff and I embarked on an epic project: we wanted to know what inhabitants of the art world think is wrong with it and how they would fix it.

Because some of our respondents wanted to speak about what’s right with the art world, we are posting a portion of the many responses in these days before the Thanksgiving holiday. We hope you will read them with the same great interest, an...

These regions are the origin of solar activity which controls space weather and causes beautiful phenomena such as aurora but in some cases also damage to satellites or power grids. Solar active regions are thought to be the result of magnetic flux concentrations - bundles of magnetic field lines - rising from deep in the solar interior and penetrating the surface. A team consisting of researchers from the Max Planck Institute for Solar System Research (MPS), The University of Göttingen, NorthWest Research Associates, and the High Altitude Observatory of the National Center for Atmospheric Research has now shown tha...
