Frontiers of Science

What if a painting were a hidden map of the heavens? In recent years, scientists have begun to treat famous canvases as puzzles to be solved with telescopes and software. Consider Vincent van Gogh’s The Starry Night: its swirling stars and glowing crescent moon might look like pure imagination, but astronomers and art historians discovered that the sky in the painting closely matches the real night sky on June 19, 1889. In fact, Venus appears in exactly the position Van Gogh painted it. Likewise, Johannes Vermeer’s View of Delft is more than a cityscape; researchers measured the angles of sunlit patches and shadows in the painting and found they align with the Sun’s position on a clear Dutch morning around 8 a.m. on September 3 or 4, 1659. It’s as if these masterpieces are cosmic records. In this article, the author plays detective with science and art, using celestial clues – star charts, sun positions, historical maps – to decode the hidden details of Van Gogh’s and Vermeer’s worlds. What emerges is a story of wonder: art created in the real light of the sky, waiting for modern "astronomers as sleuths" to unlock its secrets.

An Antarctic expedition is among the most dangerous and adventurous journeys in the world. Modern technology has made these expeditions more feasible, but the spirit of adventure and harsh realities remain. Such exploration required sacrifices, including the loss of lives and failed attempts. This raises key questions: why are humans so drawn to these perilous journeys? How has exploration turned into a scientific and strategic goal to access this remote, icy continent? This article discusses Antarctica’s discovery, the global interest it sparked, and the Antarctic Treaty—a milestone in international cooperation. It traces human engagement from the Heroic Age to the present, highlighting efforts by both developed and developing nations to protect and study this unique environment, particularly India’s growing scientific and environmental role.

DeepSeek’s rapid ascent in artificial intelligence (AI) has disrupted the sector, challenging industry norms and intensifying global competition. This analysis by the Editorial Board highlights the company’s breakthroughs, notably its cost-effective, high-performance AI model "R1" and open-source large language models (LLMs) "DeepSeek-V3" and "DeepSeek-R1".

In our relentless quest to understand the Universe, we often overlook the most intricate and profound object we have: the human brain. Weighing just 1.5 kilograms, this soft, wet tissue is a marvel of complexity, capable of solving problems, creating art, and exploring the depths of existence. Throughout history, we have sought to unravel the mysteries of thought and reasoning, constantly drawing parallels between our minds and the advanced technologies of our time. From clockwork mechanisms to modern computers, these analogies reflect our evolving understanding of intelligence and cognition. Written by one of the leading experts on AI, this article takes a journey through the lens of chess—a game long considered a benchmark for intelligence—tracing the development of Artificial Intelligence over the past 75 years. As we examine how machines have learned to play this strategic game, we will uncover the challenges and breakthroughs that have shaped the AI field, revealing the deep connection between our understanding of the mind and the machines we create.
