PBS NewsHour reports on scientists developing new ways to control mosquito populations as rising global temperatures expand the habitats where the insects and the diseases they carry can spread. The segment examines research approaches to targeting mosquitoes as warming climate conditions push the public health threat into previously unaffected regions.

Seoul has been identified as the leading city for so-called 'forever renters' — residents expected to rent for life rather than buy — as global housing costs continue to climb sharply. The report highlights how surging property prices in major cities are pushing homeownership out of reach for many, with Seoul singled out as the most extreme example of a rental-trapped population.

A new study questions the widely held idea that climate change is driving a boom in global squid populations.
