Real-time water-level monitoring across many locations is vital for flood response, infrastructure management, and environmental forecasting. Yet many sensing methods rely on fixed instruments - acoustic, radar, camera, or pressure probes - that are costly to install and maintain and are vulnerable during extreme events. We propose a passive, low-cost water-level tracking scheme that uses only LTE downlink power metrics reported by commodity receivers. The method extracts per-antenna RSRP, RSSI, and RSRQ, applies a continuous wavelet transform (CWT) to the RSRP to isolate the semidiurnal tide component, and forms a summed-coefficient signature that simultaneously marks high/low tide (tide-turn times) and tracks the tide-rate (flow speed) over time. These wavelet features guide a lightweight neural network that learns water-level changes over time from a short training segment. Beyond a single serving base station, we also show a multi-base-station cooperative mode: independent CWTs are computed per carrier and fused by a robust median to produce one tide-band feature that improves stability and resilience to local disturbances. Experiments over a 420 m river path under line-of-sight conditions achieve root-mean-square and mean-absolute errors of 0.8 cm and 0.5 cm, respectively. Under a non-line-of-sight setting with vegetation and vessel traffic, the same model transfers successfully after brief fine-tuning, reaching 1.7 cm RMSE and 0.8 cm MAE. Unlike CSI-based methods, the approach needs no array calibration and runs on standard hardware, making wide deployment practical. When signals from multiple base stations are available, fusion further improves robustness.
Prediction of Herd Life in Dairy Cows Using Multi-Head Attention Transformers
Dairy farmers should decide to keep or cull a cow based on an objective assessment of her likely performance in the herd. For this purpose, farmers need to identify more resilient cows, which can cope better with farm conditions and complete more lactations. This decision-making process is inherently complex, with significant environmental and economic implications. In this study, we develop an AI-driven model to predict cow longevity using historical multivariate time-series data recorded from birth. Leveraging advanced AI techniques, specifically Multi-Head Attention Transformers, we analysed approximately 780,000 records from 19,000 unique cows across 7 farms in Australia. The results demonstrate that our model achieves an overall determination coefficient of 83% in predicting herd life across the studied farms, highlighting its potential for practical application in dairy herd management.
Australia's beloved weather website got a makeover - and infuriated users
Australia's beloved weather website got a makeover - and infuriated users It was an unseasonably warm spring day in Sydney on 22 October, with a forecast of 39C (99F) - a real scorcher. The day before, the state of New South Wales had reported its hottest day in over a century, a high of 44.8C in the outback town of Bourke. But little did the team at the national Bureau of Meteorology foresee that they, in particular, would soon be feeling the heat. Affectionately known by Australians as the Bom, the agency's long-awaited website redesign went live that morning, more than a decade after the last update. Within hours, the Bom was flooded with a deluge of complaints.
The 12 best science fiction books of 2025
From drowned worlds to virtual utopias via deep space, wild ideas abound in Emily H. Wilson's picks for her favourite sci-fi reads of the year So: what were the best works of science fiction published this year? I will start with two new books that aren't actually new, but have only just been published in English. First up is Ice by Jacek Dukaj, originally published to great acclaim in Poland all the way back in 2007. It is an alternative history set in Europe in the early 1920s. A terrible winter grips the land, and the cause of it may be something very alien.
ChatGPT firm blames boy's suicide on 'misuse' of its technology
Adam Raine's family say the version of ChatGPT he used had'clear safety issues'. Adam Raine's family say the version of ChatGPT he used had'clear safety issues'. ChatGPT firm blames boy's suicide on'misuse' of its technology The maker of ChatGPT has said the suicide of a 16-year-old was down to his "misuse" of its system and was "not caused" by the chatbot. The comments came in OpenAI's response to a lawsuit filed against the San Francisco company and its chief executive, Sam Altman, by the family of California teenager Adam Raine. Raine killed himself in April after extensive conversations and "months of encouragement from ChatGPT", the family's lawyer has said.

Nvidia plays down Google chip threat concerns
Nvidia has claimed it is a generation ahead of rivals in the artificial intelligence (AI) industry amid growing suggestions a rival may emerge to threaten to its market dominance - and multi-trillion dollar valuation. Shares in the chip giant fell on Tuesday, following a report Meta planned to spend billions on AI chips developed by Google to power its data centres. In a statement on X, Nvidia, the world's most valuable company, said it was the only platform which runs every AI model and does it everywhere computing is done. In response, Google said it was committed to supporting both its own and Nvidia's chips. Nvidia's chips have become a critical part of powering the data centres behind many of the most popular AI tools, such as ChatGPT.
Computer maker HP to cut up to 6,000 jobs by 2028 as it turns to AI
HP has announced a lower-than-expected profit outlook for the coming year. HP has announced a lower-than-expected profit outlook for the coming year. Up to 6,000 jobs are to go at HP worldwide in the next three years as the US computer and printer maker increasingly adopts AI to speed up product development. Announcing a lower-than-expected profit outlook for the coming year, HP said it would cut between 4,000 and 6,000 jobs by the end of October 2028. It has about 56,000 employees.
Warner Music signs deal with AI song generator Suno after settling lawsuit
Warner acts such as Coldplay can choose to opt in to their music being used by Suno to create AI music. Warner acts such as Coldplay can choose to opt in to their music being used by Suno to create AI music. Warner, the world's third-largest music company and home to acts including Coldplay, Charli XCX and Ed Sheeran, is the first of the major record labels to partner officially with the company. As part of their agreement, users will be allowed to create AI-generated songs on Suno via simple text prompts using the voices, names and likenesses of the Warner acts who choose to opt in to the service. Robert Kyncl, the chief executive of Warner Music Group, said the deal showed that artificial intelligence could be "pro-artist" when it is licensed to "reflect the value of music".
Warner settles lawsuit with AI music firm and launches joint venture
Warner Music Group (WMG) will begin an artificial intelligence (AI) music venture with technology start-up Suno - a year after it sued the firm in a landmark case. As part of the settlement agreement struck between the two firms, Warner will let users create AI-generated music on Suno using the voices, names and likeness of artists who opt-in to the programme. The record label, which represents artists like Dua Lipa, Coldplay and Ed Sheeran, was among several music giants like Sony Music that sued Suno and a similar platform called Udio. AI-generated content has been controversial, with many artists voicing concerns that it could undermine human songwriters. Starting next year, Suno will roll out new advanced and licensed models to its generative-AI music platform, which allows users to create music based on simple descriptions, said Warner in a statement .
