Urban scaling research reveals that social activities and wages grow faster than population size, while physical infrastructure needs expand at a slower pace. However, continuous expansion heavily disrupts surrounding environments by replacing permeable soils with concrete and asphalt. Satellite data from Bengaluru illustrates how declining vegetation leads to acute nighttime heat islands and severe stormwater challenges. Additionally, psychological factors like induced demand ensure that expanding roadways merely invites more traffic rather than resolving congestion.

Cities are usually discussed in the language of infrastructure, economics and politics. But I’ve often wondered whether we are looking at cities through too narrow a lens. Maybe it’s time to look at them through science. Not because science has all the answers to urban problems, but because it can help us understand why cities behave the way they do, why seemingly sensible interventions sometimes fail, and why the consequences of building a city extend far beyond the structures we put up.
A city is more than an assembly of buildings, roads and people. It is a complex system in which mathematics, physics, ecology and human behaviour constantly interact. Looking at a city through these four disciplines might tell us something that conventional measures of development often miss: whether the city we are building is actually working.
Consider what happens when a city doubles in population. It would be reasonable to expect that it would need twice as many roads, twice as much infrastructure and twice as many resources. But cities do not always follow such straightforward arithmetic.
Renowned cell biologist Dr Marta Shahbazi was traveling to collect an honor from the Spanish Society for Developmental Biology when her train was involved in a massive collision near Urda. The tragedy claimed at least 69 lives, marking one of the deadliest modern rail disasters in European history and prompting Spain to declare three days of national mourning. Her death represents a devastating blow to the international molecular biology research community.
Researchers Jonah Berger and Alixandra Barasch evaluated five studies alongside thousands of online profiles to examine how photo styles shape interpersonal impressions. Audiences consistently feel greater connection toward and interest in individuals shown in unposed shots because these moments signal natural authenticity rather than careful self-curation. This perceptual edge vanishes, however, when audiences discover that the subject knew they were being photographed.
Paleontologists analyzing specimens from Guizhou Province have identified *Gerrothorax maritimus*, a Late Triassic bottom-dweller adapted to overcome the fatal dehydration typical of modern amphibians in saltwater. The animal relied on thick bony armour and gills to manage internal salt balances while hunting on the seafloor. This discovery challenges long-held scientific assumptions regarding the ecological limits and evolutionary adaptability of ancient amphibians in open marine environments.
