 Hum: the smallest city in the world In the northwest of Croatia is located Hum, a town with only 25 inhabitants. According to Guinness World Records, Hum is the smallest city in the world. It is unusual for an urban center with such a small population and land area to be considered a city. In most countries of the world this would never be accepted, but in Croatian territory it is a curious reality. Hum's origins date back to the 11th century, and both the architecture and layout of the city have evolved little since then. It was originally built as a medieval castle with the intention of future urban development. And to some extent, this happened only within the city walls. From medieval castle to Croatian city. Today, a person on foot can walk through the entire city in less than an hour. Although urban development came out of the castle walls, it is just a parking lot and a souvenir store.

 We're worrying about the wrong volcanoes, study finds A new study identifies several clusters of relatively small volcanoes that, if they were to erupt, would devastate critical infrastructure and the global economy. The most powerful volcanoes, needless to say, inflict a lot of damage and consequently attract much of our concern. But as new research published in Nature Communications points out, giant eruptions are relatively rare, while smaller eruptions occur more frequently. And because small volcanoes are capable of disrupting things like aviation, commerce and communications, they pose significant risks to modern civilization. "It's time to change the way we look at extreme volcanic risk," explains Lara Mani, lead author of the paper and a researcher at the Centre for the Study of Existential Risk at the University of Cambridge, in a press release. "We need to stop thinking in terms of colossal eruptions that destroy the world, as depicted in Hollywood mov...
