Are hotel managers becoming obsolete in the age of AI?

A recent study by the University of Surrey suggests that hotel managers may need to adapt to AI-driven system management, shifting their focus from controlling to coaching staff. Effective communication, emotional intelligence, and creativity are key strategies for managers to navigate this transformation.

Good karma for me, bad karma for you

A study by the American Psychological Association reveals that people tend to believe they've earned good things through karmic merit, while bad events in others are due to punishment. The research shows how supernatural beliefs like karma help people make sense of their experiences and feel good about themselves.

Origins of common lung cancer that affects smokers discovered

A recent study has identified the 'cell of origin' of lung squamous cell carcinoma (LUSC), a second most common type of lung cancer among smokers. The research found that basal cells expressing the gene Krt5 become dominant in the trachea and eventually invade large areas of the lung, forming tumors.
