‘People yearn for stability’: the Thames Water sewage plant at frontline of its crisis

It is a grey day in a wet week but one of Thames Water’s neglected plants is still coping. Wastewater is being pumped into the vast Maple Lodge sewage treatment centre in Rickmansworth, just off the M25, at a rate of about 3,000 litres a second, within capacity.The site manager points out the first-line screens that catch everything that will not pass through a 5mm filter. A “sheep” – a bundle of wet wipes, sanitary pads, cotton buds, condoms and indigestible bits of sweetcorn – is rotating at one edge. Credit cards and false teeth have been known to end up here

Police AI chief admits crime-fighting tech will have bias but vows to tackle it

A police chief has admitted artificial intelligence used to boost crime fighting will contain bias but pledged to combat the risks.Labour wants a dramatic expansion of police use of AI within England and Wales, with police chiefs also believing it could help keep law enforcement up to date with new criminal threats.Alex Murray told the Guardian that a new national police AI centre would recognise the risks of bias and minimise them.Bias in use of AI in policing could result in instances where algorithms – often trained on historical data reflecting past human prejudices – systematically produce unfair outcomes, such as overtargeting minority communities or misidentifying individuals based on race, gender, or socioeconomic status.Murray, the director of threat leadership with the National Crime Agency, and the national lead for AI, said: “Once you’ve recognised and minimised [bias], how do you train officers to deal with outputs to ensure that it is further minimised?“If you talk about live facial recognition or predictive policing, there will be bias, and you need to get in the data scientists and the data engineers to clean the data, to train the model appropriately, and then to test it

New datacentres risk doubling Great Britain’s electricity use, regulator says

The amount of power being sought by new datacentre projects in Great Britain would exceed the national current peak electricity consumption, according to an industry watchdog.Ofgem said about 140 proposed datacentre schemes, driven by use of artificial intelligence, could require 50 gigawatts of electricity – 5GW more than the country’s current peak demand.The figure was revealed in an Ofgem consultation on demand for new connections to the power grid. It pointed to a “surge in demand” for connection applications between November 2024 and June last year, with a significant number coming from datacentres. This has exceeded even the most ambitious forecasts

Australia v India: first women’s cricket one-day international – live

3rd over: Australia 0-17 (Healy 11, Litchfield 4) Healy batting out of her crease to Renuka, looking to cut down swing, and a drive back has a touch of leading edge about it, not far from the bowler’s outstretched hand. Stopped at mid off, though. Then beats the outside edge with one that doesn’t swing, as Healy drives. Then another leading edge! This one goes about 160 degrees around the clock face, skewing through a vacant slip. Healy gets a couple, then lifts a clunky pull shot over square leg for one, just up and other to dink it away

‘Resilience is the biggest lesson’: Raducanu is ready for revival after setbacks

Emma Raducanu has no immediate plans to appoint a new coach as she attempts to kickstart a frustrating season in the US next month. The British No 1 will play at Indian Wells and in the Miami Open in March without a full-time replacement for Francisco Roig – her ninth coach since she turned professional – with whom she parted company after her second-round exit at the Australian Open in January.“Right now I wouldn’t say I’m actively looking for a coach,” Raducanu says in Tokyo, where on Tuesday she was unveiled as a global brand ambassador for the Japanese clothes retailer Uniqlo after ending her association with Nike.“I think I had a great experience with Francis in terms of how we got on so well … the rapport was great. I think in the end, we just weren’t aligning on certain key aspects
