Scientists have developed the most accurate atomic clock ever built, according to a newly published report. The clock advances precision timekeeping, which underpins GPS navigation, telecommunications and tests of fundamental physics. Researchers say such devices lose tiny fractions of a second over billions of years, pushing the limits of measurement science and potentially prompting a redefinition of the second itself.

Bill Gates appeared on CNN's Fareed Zakaria GPS to discuss what should be done about artificial intelligence right now. He set out his view on how governments and the tech industry should respond to the rapid rise of AI, adding his voice to the growing debate among business leaders and policymakers over regulation, safety and the technology's economic impact.

Analysis of solar-driven disasters is drawing attention to the risk that space weather poses to electricity grids and digital infrastructure. Strong solar flares and geomagnetic storms could damage transformers, knock out satellite communications, GPS and internet systems, with recovery potentially taking months. The discussion highlights how modern economies remain deeply exposed to events originating on the Sun and calls for better forecasting and grid hardening.

Galileo, the European Union's satellite navigation system and alternative to American GPS, has demonstrated its first cryptographically authenticated position fix while under active spoofing attacks. The achievement means receivers could verify that a location signal genuinely comes from the satellite constellation rather than an imposter. It matters because GPS spoofing is a growing threat to aviation, shipping and critical infrastructure, and Galileo's OSNMA-style encryption offers a defence other systems lack.
- 5Fighting GPS Spoofing With Galileo's Encrypted Signals●Defeating Satellite Spoofing With Galileo’s Encryption
Galileo, the European Union's satellite navigation system, offers an encrypted signal that can help receivers detect and defeat spoofing attacks, in which fake GPS signals trick devices into reporting false positions or times. Attention is turning to how this authentication capability can be used to protect navigation systems against growing jamming and spoofing threats.
