By Paul Mozur and Adam Satariano, The New York Times Company KYIV, Ukraine — In the nearly three years since Russia’s invasion of Ukraine, the messaging app Telegram has been a lifeline for millions of Ukrainians. It provides information about coming attacks and helps communities organize food, medical aid and other support. But what has been a salvation has increasingly turned into a major source of concern.

BUDAPEST, Hungary — Moving in a dense cloud, like throngs of people walking across a crowded public square, 100 drones maneuver through the night sky in Hungary’s capital, the result of over a decade of research and experimentation that scientists believe could change the future of unmanned flight. The behavior of the swarm, made up of autonomous drones that make their own real-time decisions on collision avoidance and trajectory planning without pre-programming or centralized control, is guided by research the Hungarian scientists performed on the collective movements of creatures from the natural world. “It’s very rare that you see some technology and you say it’s beautiful,” said Boldizsár Balázs, one of the researchers working on the project.

Protect public art from vandals. Keep it indoors. Having a public art program in Denver which uses a developer’s tax to fund artists to create works of art in public spaces around the city is a great thing. Having those same works of art defaced by gangs who “mark” them with their “signs” is horrible. So until these gangs can be prevented from doing their thing, we should not be placing new public art works in places where they are sure to be defaced. That, unfortunately, means in our public parks, particularly along Denver’s wonderful Cherry Creek hike and bike trail. Murals on walls along this trail have been ravaged from Confluence Park to Colorado Boulevard, especially the huge mural across the creek from Cherry Creek Mall. Yet the Denver Arts & Venues agency continues to offer the Public Arts Program a free pass to commission new murals and other works of art on its property, as if gang markings would not inevitably follow. There are plenty of indoor locations in our city where public art works will be safe.
