The UK's Advanced Research and Invention Agency (ARIA) has chosen eight scientists who will each be given up to £50 million to allocate as they see fit, in the hopes that a high-risk, high-reward approach to research funding will deliver results that benefit UK society and fuel economic growth. ARIA is the brainchild of Dominic Cummings, an adviser to former UK prime minister Boris Johnson who has long wanted to shake up UK science funding. "A small group of people can make a huge breakthrough with little money but the right structure, the right ways of thinking," Cummings wrote in 2017. He was inspired by the US's Advanced Research Projects Agency (ARPA), which spurred computer science as a discipline and created a forerunner of the internet in the 1960s and 1970s. It did this, in the words of one of its leading scientists, by having "visions rather than goals" and because it "funded people, not projects".

Ukraine has reported downing more than two dozen Russian drones over the country's capital, Kyiv, as Russia's defence ministry announced the destruction of eight Ukrainian drones near the annexed Crimean peninsula. The extent of the damage from the rival attacks early on Sunday was not immediately clear. Kyiv Mayor Vitali Klitschko said that at least one person was wounded in the city's historic Podil neighbourhood and a fire broke out near one of its parks. Debris from downed drones fell on the Darnytskyi, Solomianskyi, Shevchenkivskyi, Sviatoshynskyi and Podil districts, Klitschko and the city's military administration said. In the Shevchenkivskyi district, debris sparked a fire in an apartment, which was quickly distinguished.

How do you find an elusive animal that most people have never even seen dead in a fish market? Matthew McDavitt, above, knows how.Melody Robbins This story was originally published by Hakai Magazine and is reproduced here as part of the Climate Desk collaboration. Peter Kyne sits down at his desk to write a eulogy for a fish he's never met. No scientist has seen signs of the critically endangered Rhynchobatus cooki, or clown wedgefish, since a dead one turned up at a fish market in 1996. Kyne, a conservation biologist at Charles Darwin University in Australia who studies wedgefish, has worked only with preserved specimens of the spotted sea creature. "This thing's dust," Kyne thinks, feeling defeated as he writes the somber news in a draft assessment of the global conservation status of wedgefish species for the International Union for Conservation of Nature. Wedgefish are a type of ray.

The paper considers the possibility of fine-tuning Llama 2 large language model (LLM) for the disinformation analysis and fake news detection. For fine-tuning, the PEFT/LoRA based approach was used. In the study, the model was fine-tuned for the following tasks: analysing a text on revealing disinformation and propaganda narratives, fact checking, fake news detection, manipulation analytics, extracting named entities with their sentiments. The obtained results show that the fine-tuned Llama 2 model can perform a deep analysis of texts and reveal complex styles and narratives. Extracted sentiments for named entities can be considered as predictive features in supervised machine learning models.

Parts of what could be a Russian drone fell on Romanian territory, Romania's Defence Minister Angel Tilvar says, two days after Ukraine said Russian drones had detonated on the NATO member's land. Romanian officials had earlier denied reports of drones falling on Romanian territory and said Russian attacks in neighbouring Ukraine did not cause a direct threat. Tilvar told local news channel Antena 3 CNN on Wednesday that parts of what was most likely a drone were discovered in the eastern Tulcea county, an area of the Danube that forms a natural border between Romania and war-torn Ukraine. "I confirm that in this area, pieces that may be of a drone were found," he said, adding that the pieces did not pose a threat. He said the area had not been evacuated because there was nothing to suggest that the parts were dangerous and said the pieces would be analysed to confirm their origin.

Almost six billion tonnes of sand and other sediment are extracted from the world's seas and oceans every year on average, according to the United Nations. The UN Environment Programme (UNEP) warned on Tuesday of the devastating toll on biodiversity and coastal communities, adding that the scale of dredging was growing, with dire consequences. "The scale of environmental impacts of shallow sea mining activities and dredging is alarming," said Pascal Peduzzi, who heads UNEP's analytics centre GRID-Geneva. He pointed to the effects on biodiversity, as well as on water turbidity, and noise effects on marine mammals. The UNEP launched a global data platform on sediment extraction in marine environments, Marine Sand Watch, which uses artificial intelligence to track and monitor dredging activities of sand, clay, silt, gravel and rock in the world's marine environment.

Geographical location is a crucial element of humanitarian response, outlining vulnerable populations, ongoing events, and available resources. Latest developments in Natural Language Processing may help in extracting vital information from the deluge of reports and documents produced by the humanitarian sector. However, the performance and biases of existing state-of-the-art information extraction tools are unknown. In this work, we develop annotated resources to fine-tune the popular Named Entity Recognition (NER) tools Spacy and roBERTa to perform geotagging of humanitarian texts. We then propose a geocoding method FeatureRank which links the candidate locations to the GeoNames database. We find that not only does the humanitarian-domain data improves the performance of the classifiers (up to F1 = 0.92), but it also alleviates some of the bias of the existing tools, which erroneously favor locations in the Western countries. Thus, we conclude that more resources from non-Western documents are necessary to ensure that off-the-shelf NER systems are suitable for the deployment in the humanitarian sector.

Russia launched a drone attack on Ukraine's Danube River port of Izmail, leading to widespread damage to infrastructure, according to the region's governor. The attack came hours ahead of talks between Russian President Vladimir Putin and his Turkish counterpart, Recep Tayyip Erdogan, which were expected to touch on ways to revive the Black Sea grain deal that Moscow abandoned in July. Ukraine and Romania disagreed over whether the attack on Izmail hit Romanian territory on the other side of the river. Foreign Minister Dmytro Kuleba said Ukraine had visual evidence of the incident. Romanian Foreign Minister Luminita Odobescu condemned the "cynical" Russian attack on Ukrainian infrastructure but said no Russian drones or debris had fallen on Romanian territory.

Debris rained from the Kyiv night sky as Russia launched air attacks on early Wednesday, killing at least two people in the Ukrainian capital, Mayor Vitali Klitschko wrote on the Telegram messaging app. Ukraine and Russia made their boldest drone and missile strikes in months on each other, with a strike in Kyiv killing two people while a strike on ships in the Black Sea and an airport near the border lasted for hours, according to local reports. "While the Russians have been retaliating brutally against Ukraine, Kyiv's incremental escalation has prevented a massive conventional (or nuclear attack) that would have obliterated Ukraine," Rebekah Koffler, president of Doctrine & Strategy Consulting and a former Defense Intelligence Agency officer, told Fox News Digital. "It's quite witty," she said. "Will this win the war for Ukraine? But it might gradually wear down the Russian people's morale."

Ukraine's forces advanced on the southern and eastern fronts during the 79th week of the country's war with Russia, reaching what experts believe to be the rear of Russia's first line of defence. But they also faced a Russian advance in the northeast that created a dilemma about where to field available troops. Ukrainian forces driving towards occupied Melitopol confirmed their recapture of Robotyne, an important Russian stronghold in western Zaporizhia, which they entered on August 20. Southern forces spokesman Oleksandr Shtupun said on August 28 that forces were busy demining the area, securing their positions and winning more territory southeast of the settlement. Geolocated footage placed them 5km (3.1 miles) southeast of Robotyne.
