Researchers develop method to grow artificial cyborg tissues with embedded nanoscale sensors

Posted: 26 Aug 2012 04:59 PM PDT

A multi-institutional research team has developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks—which mark the first time that electronics and tissue have been truly merged in 3D—allow direct tissue sensing and potentially stimulation, a potential boon for development of engineered tissues that incorporate capabilities for monitoring and stimulation, and of devices for screening new drugs.

Origami Inspires Research Into Materials That Self-Assemble When Exposed To Light

A multi-university research team led by North Carolina State University will be developing methods to create two-dimensional (2-D) materials capable of folding themselves into three-dimensional (3-D) objects when exposed to light. The effort, which is funded by a grant from the National Science Foundation (NSF), is inspired by origami and has a broad range of potential applications.

Vitamin B12 deficiency: tracking the genetic cause

Posted: 26 Aug 2012 04:29 PM PDT

Vitamin B12 is essential to human health. However, some people have inherited conditions that leave them unable to process vitamin B12. As a result they are prone to serious health problems, including developmental delay, psychosis, stroke and dementia. An international research team recently discovered a new genetic disease related to vitamin B12 deficiency by identifying a gene that is vital to the transport of vitamin into the cells of the body. This discovery will help doctors better diagnose this rare genetic disorder and open the door to new treatments.
