Forgetting someone’s name at an inconvenient moment is something almost everyone experiences. Proper names behave unlike ordinary words: they tend to vanish even when familiar nouns and general knowledge stay within reach. Explaining this phenomenon involves examining how the brain stores and retrieves names, how attention and emotion influence their encoding, and how factors such as age, stress, and linguistic background reshape the way retrieval functions.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…

Health anxiety—worrying excessively about having or developing a serious illness—is common at varying degrees. For many people the internet, social media, and symptom-checking apps are primary sources of health information. While accessible information can empower patients, it can also amplify and maintain anxiety. This article explains how and why information often makes health anxiety worse, illustrates with examples and data-based patterns, and offers practical strategies for individuals and clinicians.What is health anxiety and cyberchondria?Health anxiety ranges from occasional worry to persistent, distressing preoccupation that disrupts life. When internet use turns reassurance-seeking into a driver of anxiety, clinicians often use the…

Value-based care shifts the focus of health systems from the volume of services delivered to the outcomes that matter to patients. The central premise is simple: pay for value, not for volume. That reframing affects clinical decisions, payments, measurement, and patient engagement, and it can reduce unnecessary interventions while improving quality, equity, and affordability.The meaning behind value-driven careValue-based care seeks to optimize health outcomes for every dollar invested by:Measuring outcomes: emphasizing clinical results, functional abilities, patient-reported measures (PROMs), and overall experience instead of tallying visits or procedures.Aligning payment: implementing incentives that promote prevention, coordinated care, and demonstrable results, including shared…

Whole-person health is a practical orientation to care that treats people as integrated beings rather than a collection of isolated symptoms. It blends medical treatment with attention to mental, social, economic, behavioral and environmental drivers of health. In practice, whole-person health shifts systems from episodic, disease-focused encounters toward continuous, personalized partnerships that reduce suffering, improve outcomes and lower avoidable costs.Core components of whole-person healthPhysical health: science-backed prevention, comprehensive chronic disease management, support for mobility and physical functioning, along with careful focus on sleep, diet and regular physical activity.Mental and behavioral health: consistent screening and readily available treatment for depression, anxiety,…

Strong evidence supports exercise as a clinically meaningful intervention for depressive symptoms across ages and settings. The benefit is not uniform for every person or every protocol, so understanding the dose — frequency, intensity, time, type — and how to individualize it is essential for achieving reliable mood improvement.What the available evidence revealsMultiple randomized trials and meta-analyses indicate that exercise delivers a modest yet meaningful antidepressant effect, with pooled standardized mean differences typically ranging from about -0.3 to -0.6, reflecting symptom relief that many individuals find clinically significant.Benefits appear across both aerobic and resistance training approaches, as well as in…

Artificial intelligence moved from promise to pressure point in 2025, reshaping economies, politics and daily life at a speed few anticipated. What began as a technological acceleration has become a global reckoning about power, productivity and responsibility.How AI transformed the world in 2025 and what the future may bringThe year 2025 will be remembered as the moment artificial intelligence stopped being perceived as a future disruptor and became an unavoidable present force. While previous years introduced powerful tools and eye-catching breakthroughs, this period marked the transition from experimentation to systemic impact. Governments, businesses and citizens alike were forced to confront…

Astronomers capture new images of interstellar comet 3I/ATLAS approaching EarthFresh observations of comet 3I/ATLAS reveal its unusual structure and dynamic tails as it nears its closest approach to Earth later this month. The interstellar visitor, which originated beyond our solar system, has sparked intense interest among scientists since its discovery in July 2025.Comet 3I/ATLAS is only the third interstellar object ever detected traveling through our solar system, making every observation crucial for understanding its trajectory, composition, and behavior. Both the Hubble Space Telescope and the European Space Agency’s Jupiter Icy Moons Explorer (Juice) mission have captured detailed images of the…

Bolivia’s Carreras Pampas reveals unprecedented dinosaur trackwaysMore than 16,000 fossilized footprints discovered in Bolivia offer a vivid window into the movements of theropod dinosaurs over 100 million years ago. These tracks, preserved along an ancient shoreline, provide rare insights into how these predators navigated their environment during the late Cretaceous period.The Carreras Pampas site, located within Bolivia’s Torotoro National Park, has yielded a remarkable concentration of theropod footprints, with scientists recently identifying 16,600 impressions. This surpasses any previously documented tracksite in terms of sheer volume. The preserved tracks span roughly 80,570 square feet (7,485 square meters) and include both isolated…
