Roadways clogged by commercial vehicles and intense competition for affordable housing are imposing costs on prosperous cities and their most vulnerable residents.

Cities are the hubs of the emerging digital economy, attracting knowledge workers with higher pay and alluring lifestyles. One consequence of this concentrated prosperity is rising rents and a scramble for housing that places disadvantaged citizens in peril—as seen in the increasing rates of homelessness in cities such as Seattle. More people living in urban cores also means more commercial vehicles are needed to serve them, which is fueled by a surge in online deliveries. The resulting congestion is burdening cities with surprisingly high costs. The social stresses of the new growth should be on your radar.

A technique to manipulate electrons with light could bring quantum computing up to room temperature.

A team of researchers in Germany and at the University of Michigan have demonstrated how can shift electrons between two different , the classic 1 and 0, in a thin sheet of semiconductor.

“Ordinary electronics are in the range of gigahertz, one billion operations per second. This method is a million times faster,” said Mackillo Kira, U-M professor of electrical engineering and computer science.

A computer programme modelled on the human brain learnt to navigate a virtual maze and take shortcuts, outperforming a flesh-and-blood expert, its developers said Wednesday.

While artificial intelligence (AI) programmes have recently made great strides in imitating human brain processing—everything from recognising objects to playing complicated board games—spatial navigation has remained a challenge.

It requires the recalculation of one’s position, after each step taken, in relation to the starting point and destination—even when travelling a never-before-taken route.
