Since the groundbreaking discovery in 1911 of a zero-resistance state at 4 K – an outcome then dubbed the "impossible result" – the realm of superconductivity has captivated researchers worldwide. One of the primary aspirations since has been to elevate critical temperatures to ambient conditions, a milestone that would revolutionize energy transport, diagnostics, and information technologies, among other sectors. Recent studies have reported achieving this objective under both extreme pressures and even at standard atmospheric conditions. This colloquium provides a comprehensive overview of the present advancements in superconductivity, including findings from our dedicated research endeavors.
