1. Researchers at JILA have developed an atomic clock more precise than any previous one, capable of detecting gravity effects at the microscopic scale. 2. The clock uses a cold gas of strontium atoms trapped in an optical lattice for high precision measurements. 3. This new clock could redefine the official second and enable new applications in navigation and mineral detection.

1. Researchers at JILA have developed an atomic clock that can detect gravity effects at the microscopic scale. 2. The clock uses visible light waves for more precise timekeeping, potentially losing only one second every 30 billion years. 3. This new clock design allows detection of relativistic effects on timekeeping at the submillimeter scale, bridging the gap between quantum mechanics and general relativity.
