Muscle recovery possible in elderly mice
Biochemistry, Genetics, and Molecular Biology Over time, stem cells in damage-repairing muscle tissues struggle to regenerate. In a new study, scientists have identified a process by which the older muscle stem cell populations can be rejuvenated to funct ...
Wolves are considerably better imitators than dogs, says new study
Plant and Animal Science It is widely believed that domestication influenced the abilities of dogs to form close relationships with humans. However, the effects of domestication on the interactions between the animals have not received much attention. Alt ...
Circumbinary planets must have formed far from their current location
Earth and Planetary Science In a new study, researchers have concluded that the majority of circumbinary planets must have formed much further away from the central binary stars and then migrated to their current location. The researchers arrived at this ...

Psychology and Neuroscience Exposure to blue light during the day directly and immediately improves alertness and performance, says a new study. Researchers from Brigham and Women's Hospital (BWH) compared the effects of exposure to blue light with e ...
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 ...
‘Ionic’ liquid salts can bypass skin and treat skin infections better
Pharmacology, Toxicology, and Pharmaceutics Samir Mitragotri, a chemical engineer at the University of California, Santa Barbara, and his team demonstrated the use of ionic liquid salts in liquid form in treating skin infections. by killing bacteria and a ...
