(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.
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. Mugabe’s two most-likely successors — his wife, Grace Mugabe, and Vice President Emmerson Mnangagwa — had been jockeying […]
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.
On Oct. 1, the hashtag #Catalanreferendum took you to the world’s most popular conversation on Twitter. For more than 12 hours, Catalonia’s independence referendum became a trending topic worldwide. As would be expected, links, posts and articles from two Spanish media companies were the most virally distributed in the digital conversation. More surprisingly, the Russian […]

(Stellenbosch University) Here's some advice for landowners wanting to remove pine trees in the hope of seeing fynbos plants on their properties again: do so before the trees have grown there for more than 30 years. The longer they wait,...Show More Summary
The desired mood of your Thanksgiving meal should determine what type of alcohol you serve: red wine for a sleepy, relaxed atmosphere or spirits for a sexy, confident air. That's the conclusion of a new survey analyzing how different types of alcohol make people feel. The reasons behind the feelings...
As if you need any further reasons to attend TetZooCon, here's one more. A couple of years ago I ran into a fellow in the post-TZC-pub with a folder full of his own dinosaur drawings. Natee and I had a look, and were suitably impressed;...Show More Summary
Per the currently accepted narrative, the first bullet to hit John F. Kennedy on Nov. 22, 1963, wasn't the one that fatally injured him. It was Lee Harvey Oswald's second shot to the head that ended the president's life, and some are now saying a medical problem Kennedy suffered from...
Just as the tobacco industry aimed to quash evidence of health risks linked to smoking, a new paper claims the Sugar Research Foundation decades ago suppressed research on the sugar's negative effects. The assertion comes via University of California at San Francisco researchers who reviewed internal sugar industry documents, per...

For the first time ever, astronomers have studied a 400-meter-long "monolith-like" asteroid that has entered the Solar System from interstellar space. Observations from ESO’s Very Large Telescope in Chile and other observatories around the world show that this unique object...
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
