Dogs share our homes, streets, routines and even many environmental exposures, yet their lives unfold much faster than ours. A puppy can move from rapid physical development to adulthood within a few years, while many dogs enter their senior stage long before their owners do. This difference makes canine aging one of the most interesting subjects in modern pet science. For dog owners in the United States, Europe, the Middle East and Asia, the basic biological process is similar, but the environment surrounding a dog can be very different. Food, veterinary care, exercise, housing, climate, social interaction and access to preventive medicine can all influence a dog's quality of life. Modern veterinary research also shows that the old idea of simply multiplying a dog's age by seven is not scientifically accurate. Dogs develop particularly quickly during their first years, and aging varies considerably according to body size and breed. Why Dogs Do Not Really Age Seven Years ...

Tokelau ocean exploration has entered a new scientific phase. National Geographic Pristine Seas has begun a major expedition to study the lagoons, coral reefs, open ocean and deep-sea environments surrounding Tokelau in the Pacific Ocean. The four-week research mission is designed to create a comprehensive baseline of the territory's marine environment and provide information that can support future ocean conservation and management. The expedition began in September 2026 at the invitation of the Tokelau government and in partnership with Tokelau's Ministry of Climate, Ocean & Resilience. Scientists, local experts, educators and filmmakers are working together to document marine biodiversity from shallow reefs to deep underwater environments. According to National Geographic , the research will examine nearshore reefs, offshore waters and deep-sea habitats around Tokelau's three atolls. The resulting information is expected to help support the territory's futur...

Archaeologists working in the mountains of northeastern Uzbekistan have uncovered remarkably small stone projectile points that could add an important chapter to the story of early Homo sapiens in Central Asia. The artifacts were found at the Obi-Rakhmat rock shelter in the Tian Shan region, at an altitude of roughly 1,250 meters. Researchers studying the site's oldest archaeological layers argue that some of these tiny triangular points are compatible with arrow-like projectile technology and may date to around 80,000 years ago. The discovery is attracting attention because it potentially pushes evidence for sophisticated projectile technology in Central Asia much farther back than traditionally recognized. A September 17, 2026 report by Popular Mechanics highlighted the finding as evidence that may change how scientists understand the movements of Homo sapiens across Eurasia. The underlying research was published in PLOS ONE in August 2025 under the title "Arrow heads ...

Caffeine is one of the most widely consumed psychoactive substances in the world. Coffee, tea, cola, chocolate, energy drinks, supplements and some medicines can all contain it. Yet the experience can be remarkably different from one person to another. One individual may feel more alert and focused after caffeine, while another may notice very little change. For someone else, the same substance can be associated with nervousness, a racing heartbeat or difficulty sleeping. Recent reporting by the BBC has highlighted an important question: why does caffeine affect people so differently? The answer is not simply how much coffee someone drinks. Researchers point to a combination of genetics, brain chemistry, habitual exposure, lifestyle, medications and individual physiology. Research has identified several genes involved in caffeine metabolism and response, including CYP1A2 and ADORA2A . A systematic review examined multiple studies involving more than 1.8 million people and found e...

Marine ecology and animal behavior studies have long debated the emotional capacities of large aquatic mammals. While toothed whales and dolphins, known scientifically as odontocetes, have frequently been observed exhibiting post-mortem attentive behaviors—such as carrying or pushing dead offspring—documented evidence among baleen whales has remained extremely scarce. That paradigm shifted dramatically following a groundbreaking observation captured off the coast of Australia. This exceptional event offers unprecedented insights into marine mammal psychology, maternal attachment, and the profound emotional depth of oceanic giants. The Discovery off the Queensland Coast In July 2025, an extraordinary natural event unfolded approximately one kilometer off the southern Gold Coast of Queensland, Australia. Andrew Mulville, a rescue boat captain and staff member working with the Sea World Foundation, noticed two adult humpback whales behaving in an unusual manner. Initially appearing as...
