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.How are health anxiety and cyberchondria defined?Health anxiety can span from brief, manageable concern to ongoing, overwhelming preoccupation that interferes with daily functioning. When online activity transforms the search for reassurance into…

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.What makes proper names specialProper names are labels with low semantic redundancy. Unlike the word “dog,” which connects to traits, actions, and contexts, a name like “Sarah” has few intrinsic clues linking it to meaning.…

A safer path forward for lithium-ion batteriesBold innovation in battery chemistry is reshaping how safety and performance can coexist. A new electrolyte design developed by researchers in Hong Kong offers a promising way to reduce fire risks without disrupting how today’s lithium-ion batteries are made.Lithium-ion batteries have quietly evolved into essential components of everyday technology, energizing smartphones, laptops, electric vehicles, e-bikes, medical devices and a vast range of tools that define modern living. Although known for strong performance and dependable operation, these batteries also possess an intrinsic hazard that has grown more apparent as their adoption has widened. Fires associated…

Whole-person health represents a practical approach to care that views individuals as interconnected beings instead of a set of separate symptoms, combining clinical treatment with consideration for mental, social, economic, behavioral and environmental influences on health, and in practice moves systems away from sporadic, disease-centered visits toward ongoing, tailored collaborations that ease suffering, enhance outcomes and reduce unnecessary costs.Core components of whole-person healthPhysical health: evidence-based prevention, chronic disease management, function and mobility, and attention to sleep, nutrition and exercise.Mental and behavioral health: routine screening and accessible treatment for depression, anxiety, substance use, trauma and stress-related conditions.Social determinants of health: food…

Artificial intelligence shifted from a hopeful breakthrough to an urgent global flashpoint in 2025, rapidly transforming economies, politics and everyday life far faster than most expected, turning a burst of tech acceleration into a worldwide debate over power, productivity and accountability.How AI reshaped the global landscape in 2025 and what lies aheadThe year 2025 will be remembered as the point when artificial intelligence shifted from being viewed as a distant disruptor to becoming an unavoidable force shaping everyday reality, marking a decisive move from experimentation toward broad systemic influence as governments, companies and citizens were compelled to examine not only…

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 evidence showsMultiple 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 supervised…

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…

A study suggests that a volcanic eruption might have set off the Black DeathNew research proposes that a massive volcanic eruption in the mid-14th century may have set off a chain of events leading to the Black Death, one of the deadliest pandemics in human history. By combining climate data from tree rings, ice cores, and historical records, scientists are shedding new light on how environmental and societal factors intersected to create a perfect storm 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…
