In a first for United States Army doctors, Burrage received an ear transplant that was grown from her own tissue inside her own body. A team, led by Lieutenant Colonel Owen Johnson III, the chief of plastic and reconstructive surgery at William Beaumont Army Medical Center in El Paso, Texas, harvested cartilage from Burrage’s ribs, carved it into the shape of an ear, and implanted it under the skin in her arm. There, it developed blood vessels, which Johnson says will allow Burrage to regain feeling in the ear once it’s healed. In an announcement released on Monday, Johnson called the operation a success.

According to new calculations, we may have a little less time to prepare for a star on course to kiss the edges of our Solar System.

Yep. Dwarf star Gliese 710, which we’ve known about for some time, could now arrive in 1.29 million years, instead of the previously calculated 1.36 million years.

Gliese 710 is what is classified as a rogue star — one that has gone roaming across the galaxy, free of the gravitational chains that normally hold stars in position.

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.
