Researchers create faster and cheaper way to print tiny metal structures with light      (via sciencedaily.com)     Original source 

Researchers have developed a light-based means of printing nano-sized metal structures that is 480 times faster and 35 times cheaper than the current conventional method. It is a scalable solution that could transform a scientific field long reliant on technologies that are prohibitively expensive and slow. Their method is called superluminescent light projection (SLP).

Our surprising magnetic galaxy      (via sciencedaily.com)     Original source 

A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from the galactic average by a high degree. The findings suggest magnetic fields strongly impact star-forming regions which means they played a part in the creation of our own solar system.
