A strike on Kyiv set a building on fire, with footage showing people escaping the blaze as smoke filled the structure. The incident comes amid ongoing Russian attacks on the Ukrainian capital, which have repeatedly hit residential and urban areas, forcing residents to evacuate buildings during air raids.
- 5AI Data Centers' Waste Heat Becomes Urban ProblemβAI Data Centers Release Heat, Posing New Problem for Cities | As facilities to power artificial intelligence grow larger
As artificial intelligence data centers grow larger and increasingly cluster together in cities, they release significant amounts of hot air into surrounding neighborhoods, creating a new environmental and planning challenge. The waste heat adds to urban heat island effects, raising questions about where these facilities should be built and how cities will manage the extra warmth as AI infrastructure expands.
- 6Higher Pollution Levels Linked to Slower Marathon Race TimesβHigher Pollution Levels Linked to Slower Race Times Across Six World Marathon Majors
A new study reports that higher air pollution levels are associated with slower finishing times across the six World Marathon Majors, including Boston, London, Berlin, Chicago, New York and Tokyo. The findings suggest poor air quality measurably affects elite and amateur runners' performance on race day, adding an environmental dimension to debates over race scheduling and urban air standards.
- 7Students build electric car that filters pollution while drivingβStudents develop electric car that captures particulate matter while driving
A team of students has developed an electric car capable of capturing particulate matter from the air as it drives, according to a report carried by Tech Xplore. The project combines electric mobility with active air filtration, potentially allowing vehicles to reduce urban pollution rather than merely produce less of it. Details about the team, the university involved and how the capture technology works have not been disclosed in the available reporting.
- 8Arrest made after Sacramento shooting near Urban Air kills oneβSuspect arrested after Sacramento shooting outside Urban Air left 1 woman dead, 1 injured
Police have arrested a suspect in a shooting outside an Urban Air trampoline park in Sacramento that left one woman dead and another person injured. The arrest came shortly after the attack, which drew a large police response to the popular family entertainment venue. Authorities have not yet released details on a possible motive or the identity of the suspect.
- 9Study maps climate actions that protect urban healthβΌSystematic overview of climate actions for health in cities
A systematic overview published in Nature reviews climate actions taken by cities and assesses their effects on public health. The work compiles existing research on measures such as emissions reduction and urban adaptation, aiming to give policymakers a clearer picture of which interventions deliver health benefits. It arrives as city governments face growing pressure to protect residents from heat, air pollution and other climate-related risks.

An art history class has been examining Berlin as a city where public monuments, memorials and street art function as an open-air museum. The course treats the German capital's urban landscape itself as the exhibit, covering how history is marked in public space. Details about the institution, the instructor and student response were not available, so the scope of the programme remains limited to this description.
- 11Wingless Prototype Aircraft Completes First Hover and Short FlightβWingless Prototype Aircraft Achieves First Hover and Short Flight
A wingless prototype aircraft has carried out its first hover and a short flight, a milestone in alternative aircraft design. The aircraft relies on engines and control systems rather than conventional wings for lift. Observers are weighing what the test means for future aviation, from urban air mobility to new military designs, while others question how far the concept can be scaled.
