Mapping informal settlements is crucial for addressing challenges related to urban planning, public health, and infrastructure in rapidly growing cities. Geospatial machine learning has emerged as a key tool for detecting and mapping these areas from remote sensing data. However, existing approaches often treat spatial units independently, neglecting the relational structure of the urban fabric. We propose a graph-based framework that explicitly incorporates local geographical context into the classification process. Each spatial unit (cell) is embedded in a graph structure along with its adjacent neighbors, and a lightweight Graph Convolutional Network (GCN) is trained to classify whether the central cell belongs to an informal settlement. Experiments are conducted on a case study in Rio de Janeiro using spatial cross-validation across five distinct zones, ensuring robustness and generaliz-ability across heterogeneous urban landscapes. Our method outperforms standard baselines, improving Kappa coefficient by 17 points over individual cell classification. We also show that graph-based modeling surpasses simple feature concatenation of neighboring cells, demonstrating the benefit of encoding spatial structure for urban scene understanding.

Danish PM calls for strong answer from EU leaders to Russia's hybrid attacks EU leaders have met in Copenhagen under pressure to boost European defence after a series of Russian incursions into EU airspace, and days after drones targeted Danish airports. Danish Prime Minister Mette Frederiksen told reporters that from a European perspective there is only one country... willing to threaten us and that is Russia, and therefore we need a very strong answer back. The incursions have become most acute for countries on the EU's eastern flank such as Poland and Estonia. A number of member states have already backed plans for a multi-layered drone wall to quickly detect, then track and destroy Russian drones. We meet at a time when Russia have intensified their attacks in Ukraine, where we have seen Russian airspace violations and unwanted drone activity in several European countries, Frederiksen told a news conference after the talks had concluded.

The White House announced a $50 million investment in artificial intelligence research to predict cancer progression and minimize treatment side effects in children.

The Interior Department tests AI-controlled lawnmowers on the National Mall as part of the Trump administration's effort to save taxpayer dollars and boost efficiency.

President Trump has announced a 20-point peace plan to end the war in Gaza, showing various lines of Israeli troop withdrawal should President Trump's plan go ahead. BBC Verify has analysed this map alongside the latest satellite imagery and the Israeli military's control of Gaza. Prime Minister Starmer says the move will revive the hope of peace but Israel says it is nothing but a reward for jihadist Hamas. BBC Verify's Merlyn Thomas looks at the latest Israeli strikes on buildings in Gaza City city over the weekend. BBC Verify analyses footage of the suspected drone attacks and images of a device found after the incident.

Yoav Litvin is an Israeli-American doctor of psychology/neuroscience, a writer and photographer. On September 17, the late-night talk show host Jimmy Kimmel was suspended after remarks he made about the death of right-wing activist Charlie Kirk. Days later, he was reinstated following liberal upheaval. In his first appearance back on air, Kimmel read US President Donald Trump's post on Truth Social: "I can't believe ABC fake news gave Jimmy Kimmel his job back." Without missing a beat, Kimmel responded, "You can't believe they gave me my job back. I can't believe we gave you your job back!"

The Stream Why does misinformation spread faster than truth? We examine how online misinformation spreads and the efforts to stop it. From bots pushing ready-made talking points, to AI generating information that isn't always reliable, to pages distorting images and bending facts - online misinformation is everywhere. So how can people tell what's real? And is it even possible to build immunity against misinformation in today's digital world?

An entire family - a married couple and their two young sons - have been killed in an overnight Russian drone attack in Ukraine's north-eastern Sumy region, local officials have said. Regional head Oleh Hryhorov said a residential building was hit in the village of Chernechchyna. The bodies of the two children, aged four and six, and their parents were later recovered from the wreckage. Ukraine's air force said its units shot down 46 out of 65 Russian drones across the country - but there were 19 direct hits in six locations. Russia's military has not commented.

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? At least 4 killed in major Russian drone, missile attack on Ukraine's Kyiv Russia's President Vladimir Putin said his forces are prevailing in what he described as a "righteous battle" in Ukraine . "Our fighters and commanders go on the attack, and the entire country, all of Russia, is waging this righteous battle and working hard," he said.

Japan's Kioxia sees AI driving strong memory growth for years Kioxia has been aggressively investing in its main chip factories as it aims to close the gap to rivals Samsung and SK Hynix. Kioxia anticipates demand for NAND storage will grow by roughly 20% each year as AI data center operators keep scaling up. The Tokyo-based memory maker is confident that the market will sustain that rapid clip of expansion and is making investment decisions on a monthly basis to ensure its new plant is up to the task of filling the demand, Executive Vice President Tomoharu Watanabe said. Kioxia's specialty is in NAND flash memory, which is used everywhere from smartphones and laptops to the fast-access sections of data center operations. Demand is strong, especially from hyperscalers who need chips for generative AI purposes," Watanabe said on Tuesday. We're also hearing from customers who need to replace data center servers they installed five to six years ago, as well as some saying they can't get enough hard drives."
