Swarms of cyborg insects controlled remotely via electrical implants can now operate underwater, thanks to tiny diving suits supplying them with oxygen - which could one day enable them to explore Mars. Hirotaka Sato at Nanyang Technological University in Singapore and his colleagues first demonstrated in 2021 that Madagascar hissing cockroaches () could be remotely controlled with electrodes embedded in sensory organs known as cerci. In 2024, they demonstrated that a swarm of 20 of these cyborg insects could coordinate. The aim was to develop biological robots equipped with infrared sensors that could be released in large numbers after natural disasters to search for survivors. Cockroaches represent a ready-made platform for such applications with a working fuel source, efficient locomotion and in-built reflexes to dodge obstacles - capabilities that engineers still struggle to replicate mechanically at such a small scale.

'Digging with a needle': Generals stall peace as Sudan's el-Obeid burns As drone attacks rain down on el-Obeid and the Rapid Support Forces (RSF) tighten their months-long siege, the capital of North Kordofan has emerged as the latest flashpoint in Sudan's grinding war of attrition. Despite mounting international alarm and renewed US diplomatic pressure aimed at securing a nationwide truce, Sudan's warring generals remain deeply entrenched. Both the Sudanese Armed Forces (SAF) and the RSF appear locked in a pursuit of outright military victory, largely sustained by a continuous flow of foreign weapons. Through the lens of the escalating crisis in el-Obeid, a grim reality is unfolding: Civilian suffering is increasingly weaponised amid polarised domestic narratives, while geopolitical manoeuvring repeatedly stalls any viable path to peace. El-Obeid holds immense strategic value.

Seattle’s World Cup Pride Match went on despite objections from Iran and Egypt’s soccer federations, becoming a celebration of free expression, inclusion, and the global game.

Game Theory: Why did Africa boycott the 1966 World Cup? Game Theory Why did Africa boycott the 1966 World Cup? A record 10 African teams are competing at the 2026 World Cup. But 60 years ago, not one African nation played in the 1966 World Cup. Al Jazeera's Samantha Johnson looks at the 1966 boycott that helped reshape the tournament for generations to come. Why are World Cup tickets so expensive?

Who will control Africa's AI infrastructure, and at what cost? In April, African Union ministers gathered in Tangier, Morocco, to discuss artificial intelligence at a moment when governments across the continent are racing to develop AI strategies, attract investment and expand digital infrastructure. Beneath the enthusiasm, however, sits a more fundamental question. As foreign technology companies invest in data centres, cloud services and AI systems across Africa, how much control will African countries ultimately have over the infrastructure on which those technologies depend? The debate reflects a broader shift in how policymakers are thinking about AI.

AI-assisted interviews promise to reduce respondent burden in surveys by allowing respondents to describe experiences naturally while an AI system noisily maps those accounts into structured survey variables. That mapping is a measurement process that is fallible, versioned, adaptive, and potentially behaves differently across subgroups. This paper proposes Adaptive Matrix Validation (AMV), a design in which each respondent completes an AI-assisted interview, which is then mapped into tabular data by the AI. Respondents are also asked a small, randomized set of structured questions, which are used for statistical adjustment. The estimator first calibrates the mapped values using validation answers from other respondents, then corrects the remaining error with the validation answers observed for the target respondent. The paper develops estimators for item means, subgroup estimates, and regression coefficients when outcomes, predictors, or both are mapped from interviews. It also gives planning formulas the number of validation questions required and the sample size. A design-calibration simulation, an American Time Use Survey emulation, and a CHAMPS verbal-autopsy narrative study show when sparse validation can improve precision and when it cannot
