Some companies are "stuck in neutral" in their approach to artificial intelligence, according to Microsoft's UK boss, who said a significant number of private and public sector organisations lack any formal AI strategy. A Microsoft survey of nearly 1,500 UK senior leaders across public and private sectors, as well as 1,440 employees, found that more than half of executives feel their organisation has no official AI plan. Roughly the same proportion report a growing gap in productivity – a measure of economic efficiency – between employees who use AI and those who do not. "Some organisations appear to be stuck in neutral, caught in the experimentation phase, rather than in the deployment [of AI]," said Darren Hardman, the tech company's UK chief executive. Microsoft, the biggest financial backer of the ChatGPT developer, OpenAI, has been pushing AI's deployment in the workplace through autonomous AI agents – tools that can carry out tasks without human intervention.

In a warming world, migratory birds face many existential threats. Scientists rely on a combination of methods to track the timing and location of their migrations, but each has shortcomings. And there's another problem: Most birds migrate at night, when it's more difficult to identify them visually and while most birders are in bed. For over a century, acoustic monitoring has hovered tantalizingly out of reach as a method that would solve ornithologists' woes. Now, finally, machine-learning tools are unlocking a treasure trove of acoustic data for ecologists.
