Repetitive negative thinking mediates relationship between self-esteem and burnout in students, study finds When people are highly stressed for prolonged periods of time, they can sometimes experience a state known as burnout, characterized by pronounced emotional, mental and physical exhaustion. The stressors leading to burnout could be personal, such as family conflicts or the end of a relationship, as well as academic or professional, such as studying a lot for exams or working long hours while taking very few breaks or vacations. /news/2025-10-repetitive-negative-relationship-esteem-burnout.html Social Sciences Education Sun, 05 Oct 2025 09:00:01 EDT news678703984 Gap-controlled infrared method enables analysis of molecular interfaces A novel spectroscopic method developed at Institute of Science Tokyo, Japan, enables highly sensitive analysis of molecules at material interfaces, using a combination of conventional ATR-IR, precise gap-control and advanced data processing.
