Archaeologists rarely identify a settlement from one object. They combine buildings, hearths, tools, food remains, activity areas, and patterns of rebuilding to understand a site.

New research led by University of the Witwatersrand and University of Southern California paleoanthropologists sheds more light on one of the most debated transitions in human evolution: when our ancestors stopped regularly climbing trees and committed fully to walking on two legs.

These tiny instabilities could play an outsized role in energizing the Sun’s corona.Two new reports revealed shifting AI usage trends across the UK, with workers spending heavily on generative AI (genAI) tools and consumers increasingly turning to the technology to access news.
A study by Deloitte found UK workers spend an estimated £958 million of their own money annually on genAI to do their jobs. Of the 25,000 UK workers surveyed, 63% knowingly used genAI for their jobs and 17% paid for at least one tool themselves. Almost a quarter claimed to use genAI every day.
The findings suggested AI adoption is moving ahead of formal workplace policies, raising concerns over training and employer oversight. Nearly a third said they used the technology without their employer’s knowledge, while 65% said their organisation lacked convincing leadership on how AI should be used.
Around half of workplace genAI users said they had received no formal training on using the technology safely and effectively.
Workers said genAI saved them an average of 70 minutes a week, yet 23% reported a stigma around deploying it. In addition, 64% of weekly users were concerned managers would think the technology could do their jobs.
The survey found workplace usage remained relatively focused on routine daily tasks, with 43% claiming to deploy the technology to search for information or draft emails and 31% stating it helped them generate summaries.
“The challenge is no longer getting people to use genAI, it’s how businesses meet this growing demand in a way that is secure, responsible and creates lasting value,” noted Hayley McKelvey, chief AI officer at Deloitte UK.
AI news
A survey by Ofcom revealed AI is also becoming a prominent route into news. The UK watchdog found one in five adults used AI services to keep up with the news, while 21% of UK adults had used an AI app or service to access news during the previous month. ChatGPT was the most popular AI service for news, reaching 13% of adults.
Online intermediaries, including social media, search engines, news aggregators and AI tools were used by 73% of adults to access news, compared with 57% who went directly to publishers’ websites and apps.
Despite the shift towards digital intermediaries, around 56% of adults said they were less trusting of an AI-written news story than one written by a human.
Ian Macrae, director of market intelligence at Ofcom, said the shift meant public service media “must continue to evolve their distribution strategies to continue to meet audiences where they are”.

An ethereal and magnificent display of gas and dust stretches across the cosmos in a spectacular new image captured by NASA's James Webb Space Telescope.
Glowing wisps of translucent gas and dust paint a striking image of the star-forming region IC 348 in this new JWST snapshot. In the image, you can see IC 348, a region found about 1,000 light-years away.
In this vast expanse of gas and dust, cold molecular hydrogen gas collapses to create new stars. And this image has no shortage of suns, with twinkling stars speckling the entire cosmic landscape, diffraction spikes and all.
But while this is a star-forming region, objects are found here as well. This image was captured as part of a scientific search for brown dwarfs, which are objects that form like stars but aren't massive enough to kickstart hydrogen fusion in their cores.
Brown dwarfs are one of the great mysteries of our universe. Not as massive as the least massive stars, but more massive than the biggest planets, brown dwarfs are strange objects stuck in the middle.
Brown dwarfs do emit some light and heat, which helps scientists to find them, though doing so can be tricky, as they're much cooler than stars and not that bright (at least in visible light). However, despite being dim, they give off infrared radiation, allowing them to be spotted by infrared instruments aboard space telescopes like JWST.
This incredible new image is part of an observing program that aims to use JWST to find and study the smallest brown dwarfs. In 2022, researchers looking at IC 348 found brown dwarfs just a few times more massive than Jupiter, so they were on the very small end. Researchers hope to find even smaller brown dwarfs to help them better understand how these strange objects form and vary across space.
