Arrowheads reveal the presence of a mysterious army in Europe’s oldest battle гей член Today, the lush, green valley surrounding the Tollense River in northeast Germany appears to be a serene place to appreciate nature. But to archaeologists, the Tollense Valley is considered Europe’s oldest battlefield. An amateur archaeologist first spotted a bone sticking out of the riverbank in 1996. A series of ongoing site excavations since 2008 has shown that the thousands of bones and hundreds of weapons preserved by the valley’s undisturbed environment were part of a large-scale battle 3,250 years ago. The biggest mysteries that researchers aim to uncover are why the battle occurred and who fought in it. These are questions that they are now one step closer to answering. ozens of bronze and flint arrowheads recovered from the Tollense Valley are revealing details about the able-bodied warriors who fought in the Bronze Age battle. The research team analyzed and compared the arrowheads, some of which were still embedded in the remains of the fallen. While many of these weapons were locally produced, some bearing different shapes came from a region that now includes modern Bavaria and Moravia. The outliers’ presence suggests that a southern army clashed with local tribes in the valley, and researchers suspect the conflict began at a key landmark along the river. Back to the future Scientists are harnessing the power of artificial intelligence to detect hidden archaeological sites buried below the sand of the sprawling Rub‘ al-Khali desert. The desert spans 250,000 square miles (650,000 square kilometers) on the Arabian Peninsula, and its name translates to “the Empty Quarter” in English. To unravel the secrets of the desolate terrain, researchers are combining machine learning with a satellite imagery tech

Hong Kong plans to install thousands of surveillance cameras. Critics say it’s more proof the city is moving closer to China юрист по таможенным вопросам Glance up while strolling through parts of downtown Hong Kong and, chances are, you’ll notice the glassy black lens of a surveillance camera trained on the city’s crowded streets. And that sight will become more common in the coming years, as the city’s police pursue an ambitious campaign to install thousands of cameras to elevate their surveillance capabilities. Though it consistently ranks among the world’s safest big cities, police in the Asian financial hub say the new cameras are needed to fight crime – and have raised the possibility of equipping them with powerful facial recognition and artificial intelligence tools. That’s sparked alarm among some experts who see it as taking Hong Kong one step closer to the pervasive surveillance systems of mainland China, warning of the technology’s repressive potential. Hong Kong police had previously set a target of installing 2,000 new surveillance cameras this year, and potentially more than that each subsequent year. The force plans to eventually introduce facial recognition to these cameras, security chief Chris Tang told local media in July – adding that police could use AI in the future to track down suspects. In a statement to CNN, the Hong Kong Police Force said it was studying how police in other countries use surveillance cameras, including how they use AI. But it’s not clear how many of the new cameras may have facial recognition capabilities, or whether there’s a timeline for when the tech will be introduced. Tang and the Hong Kong police have repeatedly pointed to other jurisdictions, including Western democracies, that also make wide use of surveillance cameras for law enforcement. For instance, Singapore has 90,000 cameras and the United Kingdom has m
