A team of researchers have created a 'liver on a chip,' a model of liver tissue that replicates the metabolic variations found throughout the organ and more accurately reflects the distinctive patterns of liver damage caused by exposure to environmental toxins, including pharmaceutical overdose.

With over two-thirds of US adults owning a smartphone, and the rise in miniaturized sensors that are used for remote health monitoring, mobile health (mHealth) is beginning to experience a boom. While the technology has the potential to expand access to services, and improve personal wellness and public health, such benefits may not be fully realized unless greater privacy and security measures are implemented.

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have created a new type of tissue chip that can better represent human tissues compared with current chips, and can be more widely used for drug testing. By engineering the chips as a silk gel, the researchers circumvented many of the problems with existing devices. The new chip also has the potential to someday be an implantable treatment itself.
Scientists have, for the first time, been able to tell apart features distanced only 5 nanometers from each other to achieve the so far highest resolution in optical microscopy. The technology, also called 'discrete molecular imaging', enhances the team's DNA nanotechnology-powered super-resolution microscopy platform with an integrated set of new imaging methods.

A new procedure that combines video-assisted surgery with real-time image guidance is helping surgeons remove lung nodules while preserving healthy tissue. The procedure was developed and is being tested at the NIBIB-funded Advanced Multimodality Image Guided Operating Suite (AMIGO). Read the article at www.rsna.org/news
Dr. Gordana Vunjak-Novakovic and her colleagues have managed to create living bone from stem cells. First, they made a CT scan to create a 3-D image of each pig’s jaw. From cow bone, they sculpted a “scaffold” — a three-dimensional copy of the pig bone. Read more at New York Times.
