At inference time, these models are computationally intensive, especially with volumetric data.

This Philips Norelco is already a champion of versatility matched with low cost--a Swiss army knife of beard, head, burns, and eyebrow guards with a nose trimmer to boot. The trimmer is high-rpm, but still quiet. The guardless blade shaves closer than most, and the shaving foil is even better. The battery lasts more than five hours. Its metal chassis offers comforting durability and heft. And unlike Philips' 9000 series, it can trim while plugged into the wall. The only real drawback is all those guards are difficult to sort and keep track of.

In essence, these tools exploit the stability and spherical symmetry of Gaussian distributions.

Artificial intelligence (AI) has been used to find two previously undiscovered possible cave entrances on the Moon, which could support human survival on future space missions. Daniel Le Corre, a PhD researcher at the University of Kent, surveyed less than 0.3% of the lunar surface before finding the two pits. The South Marius Hills Pit, which the university said was previously overlooked by researchers, is in an area thought to be rich in lava tubes, while the Bel'kovich A Pit is close to the Moon's north pole and more likely to be a source of water. The pits were detected using an AI model that was trained to scan publicly available Nasa images and identify pits based on their distinctive shape. The AI model is named Essa, which is short for entrances to sub-surface areas and a nod to the Cornish name of Mr Le Corre's hometown, Saltash.

Unscrupulous foreign firms are using AI-generated images and false back stories to pose as family-run UK businesses to lure in shoppers. Customers say they feel completely ripped off after believing they were buying from independent boutiques in England but were delivered cheap clothes and jewellery, mass-shipped from warehouses in east Asia. Among the websites is C'est La Vie, a shop purporting to be run by couple Eileen and Patrick for 29 years and based in Birmingham's historic Jewellery Quarter - but with a returns address in China. Consumer guide Which? said the growing use of AI tools was making it possible for fraudsters to mislead the public on an unprecedented scale. Another website appearing to use AI-generated images is Mabel & Daisy, a seemingly quintessential, mother and daughter-owned clothing firm, which claims to be based in Bristol but has an address in Hong Kong.

Can Ukraine restore its pre-war borders? Why are Tomahawk missiles for Ukraine a'red line' for Russia? Is Russia testing NATO with aerial incursions in Europe? Russian President Vladimir Putin said his forces have captured almost 5,000 square kilometres (1,930sq miles) of Ukrainian territory so far this year, and Moscow retains the strategic initiative on the battlefield. Russian troops have captured the Ukrainian villages of Novovasylivka in the southeastern Zaporizhia region and Fedorivka in the eastern Donetsk region, Russia's defence ministry said.

Despite representing nearly one-third of the world's languages, African languages remain critically underserved by modern NLP technologies, with 88\% classified as severely underrepresented or completely ignored in computational linguistics. We present the African Languages Lab (All Lab), a comprehensive research initiative that addresses this technological gap through systematic data collection, model development, and capacity building. Our contributions include: (1) a quality-controlled data collection pipeline, yielding the largest validated African multi-modal speech and text dataset spanning 40 languages with 19 billion tokens of monolingual text and 12,628 hours of aligned speech data; (2) extensive experimental validation demonstrating that our dataset, combined with fine-tuning, achieves substantial improvements over baseline models, averaging +23.69 ChrF++, +0.33 COMET, and +15.34 BLEU points across 31 evaluated languages; and (3) a structured research program that has successfully mentored fifteen early-career researchers, establishing sustainable local capacity. Our comparative evaluation against Google Translate reveals competitive performance in several languages while identifying areas that require continued development.
