Plus: who wants to build ICE's massive detention centersFebruary 23, 2026 This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. Inside Chicago’s surveillance panopticon Chicago has tens of thousands of surveillance cameras—up to 45,000, by some estimates. That’s among the highest numbers per capita in the US.

Her doctor couldn’t diagnose the cause but said a good, supportive bra could help. A professor of biomechanics, Wakefield-Scurr thought she could do a little research and find a science-backed option. Two decades later, she’s still looking.Wakefield-Scurr now leads an 18-person team at the Research Group in Breast Health at the University of Portsmouth in the UK. And as more women take up high-impact sports, the need to understand what makes a good bra grows, she says her lab can’t keep up with demand.
