Addressing the rapidly growing user base around GraphQL, The Linux Foundation has launched the GraphQL Foundation to build a vendor-neutral community around the query language for APIs (application programming interfaces).
The startup Precise Bio says it can replace donated eyes with 3D-printed corneas
Heres a futuristic problem that may not have occurred to you: If self-driving cars really catch on and the number of traffic fatalities plunges, so will the number of organs available for transplant. Currently, about 20 percent of donated organs come from people who die in car accidents.
Luckily, theres a futuristic solution: 3D-printed organs. This technology is far from ready for the clinic, as researchers are still trying to figure out how to print out complex tissue structures with blood vessels and nerves. But for one early indicator of progress in this field, look to the eye.
Precise Bio, a North Carolina-based startup founded by several professors at the renowned Wake Forest Institute for Regenerative Medicine, is working on bioprinting tissues for a variety of medical applications. The company just announced that its first products will be for the eyestarting with a human cornea suitable for transplantation. We plan to put our printers in eye banks, says Precise Bio CEO Aryeh Batt.
Bioprinters are a specialized type of 3D printers. Instead of putting down layers of plastic or metal to gradually build a structure, they put down layers of cells and biocompatible materials to build tissue.Photo: Precise Bio Precise Bio's bioprinter uses a technique called laser-induced forward transfer to propel droplets of bioinks onto a Petri dish or slide.
In an exclusive interview with IEEE Spectrum, Batt says that his company is aiming high, and wants to eventually overhaul the whole organ transplant system. Physicians can use tissues that are printed, not taken from donors, he says. The companys bioprinters could fabricate tissues with consistent specs, or they could print custom tissues to meet a patients needs. Its a manufacturing process, says Batt. Either way, it would be a departure from todays morbid luck-of-the-draw system.
Bioprinting is a hot area of research, wit...
