Low-cost retinal scanner could help prevent blindness worldwide
This post was originally published on this siteBiomedical engineers have developed a low-cost, portable optical coherence tomography (OCT) scanner that promises to bring the vision-saving technology to underserved regions throughout the United States and abroad. Thanks to a redesigned, 3D-printed spectrometer, the scanner is 15 times lighter and smaller than current commercial systems and is made from parts costing less than a tenth the retail price of commercial systems — all without sacrificing imaging quality.
An improved vaccine for bacterial meningitis and bloodstream infections
This post was originally published on this siteResearchers have now developed a new vaccine, a native outer membrane vesicle (NOMV) vaccine, for meningitis and bloodstream infections caused by ‘meningococcal group B’ bacteria.

Artificial DNA can control release of active ingredients from drugs
This post was originally published on this siteA drug with three active ingredients that are released in sequence at specific times: What was once a pharmacologist’s dream is now much closer to reality. With a combination of hydrogels and artificial DNA, nanoparticles can be released in sequence under conditions similar to those in the human body.
