Dreaming is a nearly universal human experience, with most individuals drifting into several dreams each night, although what they see, how vivid it feels, and what they later remember can differ greatly. Researchers investigate dreams to explore how the brain handles memory, emotion, creativity, and overall activity. Although no single, definitive explanation clarifies why dreaming occurs, a growing body of evidence from neurobiology, psychology, evolutionary perspectives, and clinical research suggests a multifaceted set of purposes and underlying processes.What happens in the brain during dreamingDreams are most vivid during rapid eye movement (REM) sleep, although dreams also occur in non-REM sleep.…

Earth’s core might harbor immense concealed stores of hydrogen, a possibility that could overturn long‑standing ideas about the planet’s water origins, with a hidden cache beneath the surface potentially surpassing the volume of all existing oceans.This finding may radically shift current views of Earth’s formation and the true source of its water.Deep beneath the crust and mantle, at depths far beyond the reach of any drilling technology, Earth’s core stands as one of the planet’s most inaccessible realms; however, emerging research indicates that this hidden, extreme environment might conceal a remarkable secret: an immense reserve of hydrogen that could surpass…

Therapeutic cancer vaccines mark a transition from simple prevention to active intervention: rather than stopping infection or the emergence of disease, they are designed to teach the patient’s immune system to identify and eliminate tumor cells already present. During the last ten years, progress in immunology, genomic sequencing, and delivery platforms has pushed therapeutic vaccines beyond early concepts and small pilot studies, moving them toward practical approvals and large randomized trials. This article outlines the fundamental principles, details major modalities with representative examples, reviews clinical evidence and existing hurdles, and points to the directions the field is poised to take.What…

Large foundation models have dominated public attention in artificial intelligence due to their broad capabilities, massive training datasets, and impressive performance across many tasks. However, a parallel shift is underway. Smaller, specialized AI models are increasingly competitive by focusing on efficiency, domain expertise, and practical deployment advantages. Rather than replacing foundation models, these compact systems are reshaping how organizations think about performance, cost, and real-world impact.What Characterizes Compact, Purpose-Built AI ModelsCompact, purpose-built models are created to address tightly defined objectives. They generally incorporate fewer parameters, draw on carefully curated training datasets, and concentrate on specific sectors or functions, spanning medical…

The 2026 Consumer Electronics Show in Las Vegas was shaped by breakthroughs in AI, humanoid robotics, and cutting‑edge devices redefining modern innovation. From large-scale robotic systems to next‑generation wearables, the event provided a glimpse into a swiftly shifting technology scene and the strategic commitments companies are placing on artificial intelligence.This year, CES showcased more than just gadgets—it highlighted how AI is transforming industries, products, and the very way we interact with technology. Companies from around the globe brought their latest innovations, ranging from humanoid robots capable of factory tasks to AI-powered home appliances, smart jewelry, and next-generation chips. While some…

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.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. That sparsity produces several predictable effects:Weak…

Value-based care redirects health systems from counting how many services are provided to concentrating on the outcomes that genuinely matter to patients, built on a straightforward idea: compensation should reward value rather than volume, a shift that influences clinical choices, payment structures, evaluation methods, and patient involvement while helping curb unnecessary procedures and enhance quality, equity, and affordability.What value-based care meansValue-based care aims to maximize health outcomes per dollar spent by:Measuring outcomes: clinical results, functional status, patient-reported outcomes (PROMs), and experience rather than counting visits or procedures.Aligning payment: incentives that reward prevention, coordination, and outcomes (shared savings, bundled payments, capitation,…

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: 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, substance…

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…
