Forgetting a person’s name at an awkward moment is nearly universal. Proper names feel different from other words: they slip away while common nouns and facts remain accessible. Understanding why this happens requires looking at how names are stored and retrieved in the brain, how attention and emotion affect encoding, and how age, stress, and language experience change retrieval dynamics.Why proper names stand outProper names function as identifiers that carry minimal semantic cues. In contrast with a term like “dog,” which naturally evokes qualities, behaviors, and situational associations, a name such as “Sarah” offers almost no built‑in hints about its…

A study suggests that a volcanic eruption might have set off the Black DeathRecent studies suggest that a colossal volcanic eruption during the mid-14th century might have triggered a series of events culminating in the Black Death, one of the most lethal pandemics in human history. By integrating climate data from tree rings, ice cores, and historical documents, researchers are illuminating how environmental and societal elements converged to form an ideal scenario for the plague.Researchers have long studied the Black Death, which ravaged Europe between 1347 and 1351, claiming the lives of at least 25 million people—roughly half of the…
