Humans express four basic emotions, not six
Psychology and Neuroscience It has long been held that there are six universally recognized basic emotions that can be easily interpreted through facial expressions: happiness, sadness, fear, anger, surprise, and disgust. However, new research suggests th ...
A Be-type star with a black-hole companion
Earth and Planetary Science Scientists have discovered the first binary system ever known to consist of a black hole and a Be star. The scientists, who conducted a detailed analysis of the star’s spectrum, found that the star was accompanied by an object ...
Better gut bacteria can increase lifespan
Biochemistry, Genetics, and Molecular Biology In a new study, scientists managed to increase the lifespan of a genus of small flies by altering the symbiotic relationship between bacteria and the cells lining the intestine. The study explored age-related ...
New form of quantum matter discovered
Chemistry and Materials Science Researchers at the U.S. Department of Energy have discovered that sodium bismuthate can exist as a form of quantum matter called a 3D topological Dirac semimetal (3DTDS). This discovery of what is essentially a 3D version o ...
