Earth’s core may contain vast hidden reserves of hydrogen, reshaping theories about planet’s water origins. Beneath our feet lies a hidden reservoir that could dwarf all of Earth’s oceans. The discovery could transform our understanding of how Earth formed and where its water came from.Far below the crust and mantle, at depths unreachable by drilling technology, Earth’s core remains one of the least accessible regions of our planet. Yet new scientific findings suggest that this remote and extreme environment may hold an extraordinary secret: a vast store of hydrogen potentially equivalent to several times the volume contained in all of…

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…

A new experiment is quietly testing what happens when artificial intelligence systems interact with one another at scale, without humans at the center of the conversation. The results are raising questions not only about technological progress, but also about trust, control, and security in an increasingly automated digital world.A newly introduced platform named Moltbook has begun attracting notice throughout the tech community for an unexpected reason: it is a social network built solely for artificial intelligence agents. People are not intended to take part directly. Instead, AI systems publish posts, exchange comments, react, and interact with each other in ways…

Large foundation models have captured widespread interest in artificial intelligence thanks to their expansive capabilities, enormous training corpora, and remarkable results across diverse applications. Yet a concurrent transformation is emerging. More compact, domain-focused AI models are steadily proving their strength by prioritizing efficiency, specialized knowledge, and deployment flexibility. Instead of displacing foundation models, these streamlined systems are redefining how organizations evaluate performance, budget considerations, and practical impact.What Defines Smaller, Specialized AI ModelsSmaller, specialized models are designed with a narrow or clearly defined purpose. They typically have fewer parameters, are trained on curated datasets, and target specific industries or tasks such…
