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 reshaped the global landscape in 2025 and what lies aheadThe 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 not…

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 report a small-to-moderate antidepressant effect of exercise. Pooled estimates commonly fall in the standardized mean difference range of about -0.3 to -0.6, indicating clinically relevant symptom reduction for many people.Effects are seen for both aerobic and resistance training, and across supervised and home-based programs.…

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…

Unprecedented dinosaur trackways unveiled in Bolivia’s Carreras PampasOver 16,000 fossilized footprints unearthed in Bolivia present a vivid glimpse into the movements of theropod dinosaurs from over 100 million years ago. These tracks, preserved along an ancient shoreline, offer rare insights into how these predators navigated their environment during the late Cretaceous period.The Carreras Pampas site, situated within Bolivia’s Torotoro National Park, has revealed an extraordinary concentration of theropod footprints, with scientists recently identifying 16,600 impressions. This number exceeds any previously recorded tracksite in terms of sheer volume. The preserved tracks cover approximately 80,570 square feet (7,485 square meters) and include…

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 extensively examined the Black Death, which devastated Europe from 1347 to 1351, resulting in the deaths of at least 25 million…

NASA is preparing to launch twin spacecraft on a novel, winding journey to Mars, aiming to unlock the secrets behind the planet’s lost atmosphere.The endeavor, christened EscaPADE—an acronym for Escape and Plasma Acceleration Dynamics Explorers—is designed to execute a novel orbital path to investigate the process by which Mars progressively shed its atmosphere eons ago. This initiative, led by the University of California, Berkeley, and backed by aerospace firms Advanced Space and Rocket Lab, signifies an audacious venture in economical planetary investigation. Diverging from conventional Mars missions that utilize direct routes within narrow launch periods, EscaPADE will employ an innovative…

NASA could be on the verge of a significant overhaul as billionaire Jared Isaacman, President Donald Trump's contentious choice for administrator, presents an ambitious blueprint for the organization.Project Athena: an ambitious roadmapIsaacman, whose nomination to head NASA has been a recurring event, having been put forward, then retracted, and subsequently re-proposed, has released a 62-page report named Project Athena outlining his vision for the agency. Although certain parts are now deemed obsolete, the blueprint indicates extensive transformations, ranging from internal restructuring to bold objectives for deep-space missions. Isaacman has stressed that this document was conceived as an initial framework, designed…

Carl Linnaeus, frequently hailed as the "pioneer of contemporary taxonomy," is a name inextricably linked with the transformative reorganization of the biological disciplines. His unwavering commitment to categorization and naming conventions not only fundamentally altered the way living organisms were structured but also established the crucial groundwork for systematic biology, impacting botanical, zoological, and ecological research for hundreds of years.The Genesis of Contemporary TaxonomyBefore Linnaeus, the categorization of life forms was based on intricate descriptions and variable terminology, frequently causing ambiguity and misunderstanding among academics. The common method for describing a plant or animal involved extensive Latin expressions outlining its…

Hypatia of Alexandria, who lived from approximately 360 to 415 CE, is recognized as one of the most extraordinary individuals in the annals of ancient intellectualism. A distinguished mathematician and philosopher, she was instrumental in safeguarding, interpreting, and furthering mathematical concepts during the era of late antiquity. Her accomplishments extend beyond mere biographical interest; they signify crucial contributions to the development of mathematics amidst a period of profound societal, religious, and political upheaval.Historical Context and Intellectual EnvironmentUnderstanding Hypatia’s contributions requires situating her within the intellectual vibrancy of Alexandria, then a renowned center for learning, home to the legendary Library of…

James Clerk Maxwell is recognized as a pivotal figure in physics, largely due to his groundbreaking efforts in electromagnetism. The influence of his theoretical and empirical discoveries has spread throughout contemporary science and technology, driving progress from radio communication to the intricacies of quantum field theory. A detailed review of his primary achievements offers deep insight into how Maxwell redefined the scientific understanding of electricity and magnetism.The Foundations: Unifying Electricity and MagnetismBefore Maxwell, electricity and magnetism were primarily studied as separate occurrences, each governed by its own principles. Groundbreaking figures like Michael Faraday, André-Marie Ampère, and Carl Friedrich Gauss had…
