Researchers conduct chemical study of an old, metal-rich globular cluster

(Phys.org)—Chilean researchers have presented a chemical study of the old, metal-rich globular cluster NGC 5927. The new research determines abundances of 22 elements in seven giant stars of the cluster. The findings are available in a paper published November 8 on the arXiv pre-print repository.

Without Mugabe, is democracy coming to Zimbabwe? Probably not.

On Tuesday, after 37 years of authoritarian rule, Robert Mugabe resigned as president of Zimbabwe. That stunning move — celebrated by lawmakers cheering and citizens dancing in the streets — came after a dizzying series of events.

Uncovering the origins of galaxies' halos

Using the Subaru Telescope atop Maunakea, researchers have identified 11 dwarf galaxies and two star-containing halos in the outer region of a large spiral galaxy 25 million light-years away from Earth. The findings, published in The Astrophysical Journal, provide new insight into how these 'tidal stellar streams' form around galaxies.

Why did Russian social media swarm the digital conversation about Catalan independence?

Hidden properties of solids

Berry curvature may not be the most well-known scientific concept, but to many physicists, its direct measurement is something akin to a holy grail. A powerful unifying principle in several branches of classical and quantum physics, Berry curvature is a strange and elusive quantum mechanical property of solids. Show More Summary
