Au fost prezentate primele ceasuri nucleare ultraprecise. De ce contează pentru GPS, bănci și rețelele electrice

Scientists have introduced functional nuclear clocks, marking a significant advancement in precise time measurement systems crucial for digital infrastructure. Developed using the radioactive element thorium, these clocks matched the performance of current atomic clocks in rigorous physics experiments. Researchers from China and Europe aim to enhance their practical applications, addressing vulnerabilities in electronic systems that support communications and power plants. Nuclear clocks promise remarkable performance with lower energy consumption and greater robustness. They are less susceptible to electromagnetic disturbances and could revolutionize navigation and precise measurements. However, challenges remain, including stability issues and the rarity of thorium-229, which is also vital for cancer therapy.
