3D printed human ears, muscle and bone

The Verge reports on advances in 3d bioprinting that takes us a step closer to viable and durable structures – including ears, muscle and bone – that can be used to aid recovery from injury or illness. From the article:

“For the first time, scientists have produced 3D-printed structures made of living cells that are big enough and strong enough to replace human tissues.”

“A bioprinter, described today in Nature Biotechnology, was used to make ear, bone, and muscle structures out of plastic-like materials and living cells… a feat that has not been easy to accomplish in the past — and the structures were stable enough to be successfully implanted in rodents, the researchers report. If the technology works in humans the way it has in animals, doctors may soon find themselves using bioprinters to produce replacement cartilage and bone for people who have been injured, using a patient’s own cells.”

3-d printed turbine freezes seawater to make it drinkable – via FastCoExist

The new approach could also be significantly (up to 8 times) cheaper than existing desalination plants, most of which rely on heat to remove salt from seawater.

The device and app can be used in the field in developing nations and isolated rural areas at lower costs than traditional equipment (or where testing equipment rarely reaches) to test a range of eye functions and conditions.

3D-printed iPhone Attachment Tests For Blood-borne Parasite

The Verge reports on the development of an iPhone attachment that can help identify the presence of disease-causing parasites in the blood.

The attachment – called Cellscope Loa – uses a 3D-printed microscope base, an app and the video camera on the iPhone to identify the presence of the Loa loa parasite and reduce the testing time from over 24 hours to minutes.
