Researchers in China and Switzerland have developed electronic blood vessels that can be actively tuned to address subtle changes in the body after implantation. The blood vessels—made of a metal-polymer conductor membrane that’s flexible and biodegradable—mimic natural blood vessels, were conductive in in vitro experiments, and were able to effectively replace key arteries in rabbits. The research, published October 1 in the journal Matter, could overcome the limitations of conventional tissue engineered blood vessels (TEBVs), which serve as passive scaffolds, by coordinating with other electronic devices to deliver genetic material, enable controlled drug release, and facilitate the formation of new endothelial blood vessel tissue.

“We take the natural blood vessel-mimicking structure and go beyond it by integrating more comprehensive electrical functions that are able to provide further treatments, such as gene therapy and electrical stimulation,” says lead

Do we need a smartphone with a sliding flexible screen?

Chinese manufacturer Xiaomi is working on a concept smartphone with a flexible screen that slides around the body of the device. At least, that looks to be the case from a patent application to the US Patent & Trademark Office (USPTO), which was registered in 2019, but only published and commented on a few days ago by the website WindowsUnited.

Millions of independent contractors are making money in the gig economy, but many don’t have access to financial credit services to help grow their personal microbusinesses.

Level wants to help. The Seattle startup partners with marketplace platforms such as Dolly and Keepe, which use Level to offer workers flexible credit options that are only paid back when they earn.

Level CEO and founder David Edelstein said the company is seeing traction amid the pandemic as both supply of workers and demand for on-demand services rises. Level is on track to extend more than $1 million in cash advances by the end of the year.

“We identified an opportunity to empower people in the rapidly growing on-demand economy to grow their microbusinesses, while addressing challenges faced by labor marketplaces seeking to grow their companies,” Edelstein said.

Level graduated from Techstars Seattle last year. Edelstein previously
