Study Reveals Unexpected Links Between Spin Directions of Galaxies

An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links might suggest that the early universe could have been spinning, according to a Kansas State University study.

New Insights into Active Spinner Materials with Reconfigurable Structure and Tunable Functionalities

At the atomic level, a glass of water and a spoonful of crystalline salt couldn't look more different. Water atoms move around freely and randomly, while salt crystals are locked in place in a lattice.
