1. Background and purpose of the study Aircraft emit nanoparticles (<50 nm Note 1 in diameter) into the atmosphere, from the ground to the upper troposphere. Studies in Europe, the U.S., and Japan have reported high concentrations of particles in and around airports Ref 1, and there is worldwide concern regarding the effects on human health. The atmospheric heating effects by contrails generated from aircraft exhaust particles are also known, and research is being conducted to assess their potential impacts on climate. Particle number emissions from turbofan jet engines, which...

Cheshire Police has become the first force in the UK to use artificial intelligence (AI) as a tool during stalking investigations. The force hopes the technology will identify suspects' patterns of behaviours at a much earlier stage. Det Ch Insp Danielle Knox, who leads its stalking unit, said that while AI would never "replace the human element", it would instead "enhance" what officers currently do.

When Finnish engineer Ari Kurvi takes a hot shower or turns up the thermostat in his apartment, he’s tapping into waste heat generated by a 75-megawatt data center 5 kilometers away. As its computer servers churn through terabytes of digital information to support video calls, car navigation systems and web searches, an elaborate system of pipes and pumps harvests the cast-off energy and feeds it to homes in the town of Mantsala in southern Finland. Since it began operation about a decade ago, the data center has provided heat for...

Sony Group Corp. forecast an outlook that missed estimates despite solid sales of its games, movies and music buoying its quarterly results, and it announced a ¥250 billion ($1.7 billion) share buyback.

For the full year to March, Sony said it expects an operating profit of ¥1.28 trillion. Analysts on average expected an operating profit of ¥1.5 trillion. That was after the company calculated US tariffs to cost it some ¥100 billion.

The group behind the popular RattleCam livestreams, which showcase hundreds of rattlesnakes in California and Colorado, are expanding east.

The California livestream, which debuted in 2021, is expected to resume sometime this summer.
