President Trump has reaffirmed ICE's arrest policy after guidance that left immigration agents alarmed and confused. The episode raised questions about how enforcement priorities are being communicated within the agency and whether operations on the ground are being affected. Officials say the policy stands, but the internal miscommunication has drawn attention to morale and clarity among agents carrying out arrests.

NPR has published a guide explaining the different factions within the AI safety debate, aiming to help readers navigate an increasingly confusing and polarised discussion. The piece breaks down the competing camps and their positions on how artificial intelligence should be regulated and developed, reflecting growing public interest in understanding the argument between those worried about AI risks and those pushing for rapid progress.

Mexico and Brazil are both pushing back against the Trump administration's military approach in South America, declining to endorse or join US-led pressure tactics in the region. The two largest Latin American economies are framing their refusal as a defense of sovereignty and regional autonomy, setting up a notable rift between Washington and its southern neighbors.

A US lawmaker says the commercialization of fusion energy will 'change everything,' arguing that bringing the technology to market would transform the global energy landscape. The comments add to growing political and industry momentum around fusion, which promises abundant carbon-free power but remains years away from widespread commercial deployment.

Radio-Canada reports on new research suggesting the brain may have evolved from the fusion of two ancestral organs. The idea, tied to studies of embryonic cells, challenges the classic view of how the brain developed over evolutionary time and is drawing attention among French-speaking science and neuroscience audiences discussing its implications for biology and evolution.

A new report from the Genesis Mission examines how artificial intelligence is being applied to fusion energy research and biological design. The analysis covers AI's potential to accelerate scientific discovery in these fields, including modeling complex plasma behavior and engineering biological systems. The report is drawing attention from readers following the broader push to apply advanced computing and AI to national science and energy priorities.

Minnesota election officials held a public discussion addressing how court rulings and litigation are affecting election administration in the state. Election leaders sought to clear up confusion among voters about what the courts have decided and how those decisions affect voting procedures. The segment, covered by regional outlets, reflects ongoing public concern over election rules and legal challenges ahead of voting.

A new episode of the business series Europe's Foundry says an unnamed startup has just taken the lead in the global race to develop fusion energy. The claim positions the company ahead of better-known fusion players, though no specific company, funding amount or technical milestone is given in the headline.

A detailed technical guide to functional ultrasound imaging, a neuroimaging method that measures brain activity with high sensitivity using ultrasound waves, has been published on neuroai.science. The walkthrough covers building and understanding fUSI systems from first principles, drawing attention from researchers interested in accessible, lower-cost alternatives to fMRI for studying brain function.

Formula 1's first Friday running of the 2026 season has left paddock observers struggling to read the true competitive picture, with The Race analysing what can actually be concluded from the most confusing practice day of the new campaign. Under the brand-new engine and aerodynamic rules, times and form appear unreliable, leaving teams and fans uncertain about the real pecking order.

The International Council on Clean Transportation has released the HDV-DIFFUSE model, a tool for modelling how electric trucks will diffuse through the heavy-duty vehicle fleets of the EU27 plus three additional European countries. The model is intended to help researchers and policymakers project e-truck uptake and inform decarbonisation planning for road freight across Europe.

Reports are highlighting that Europe is moving ahead with plans to build what is described as the first real fusion power plant, a facility designed to generate electricity from nuclear fusion rather than just experimental energy gains. The project is drawing attention because fusion promises abundant clean power, and Europe's efforts are being framed as a potential milestone in bringing the technology from laboratories toward the grid.

Reports are circulating about a possible fusion of the space activities of Airbus, Thales and Leonardo, a move being described as creating a European space monopoly. The discussion, tied to aerospace industry orders and consolidation, references a La Tribune report on defense and space, with observers weighing what a combined European champion would mean for the sector.

A study published in Frontiers examines how cardiovascular fitness relates to sustained attention in older adults, using a diffusion decision model to separate effects on processing speed from decision-making quality. The modeling approach offers a finer-grained look at how fitness may support cognitive performance in aging, beyond simple reaction-time measures.

F-Droid, the largest open-source app store for Android, has officially announced it will not comply with Google's requirements, rejecting integration with the company's ecosystem. The move is being covered as a notable act of resistance from the alternative app distribution community, highlighting ongoing friction between independent Android platforms and Google's control over the operating system.

Formula 1's 2026 season produced a baffling Friday practice session, and The Race has analysed what it actually revealed about the new regulations and car performance. With entirely new engine rules and aerodynamics for 2026, teams appear to be struggling to read the data, leaving fans and pundits debating which teams are genuinely quick and which are sandbagging or simply lost.

Singapore's Tan See Leng said nuclear fusion could create economic opportunities for the country, pointing to its potential as a future clean energy source. The remarks come as governments worldwide weigh investment in fusion technology, and observers are discussing what role Singapore could play in the emerging sector given its limited land and energy resources.

Mass spectrometry, a technique for identifying gases and isotopes by their mass, is playing a growing role in nuclear fusion research. According to AZoQuantum, scientists use it to monitor plasma conditions, detect fuel impurities, and measure tritium levels in fusion experiments, helping improve reactor performance and move practical fusion energy closer to reality.

The Pennsylvania Department of Environmental Protection is inviting public comments on an air quality permit for TECfusions Keystone LLC's planned New Kensington data center in Westmoreland County. The permit would cover operation of natural gas boilers and backup generators at the facility. The comment period gives residents and advocacy groups a chance to weigh in on emissions from the site before the state issues its final decision.
