Neuroengineers have created a tiny surgical implant that can electrically stimulate the brain and nervous system without using a battery or wired power supply.

Researchers are working on an entirely new way to detect blood clots, especially in pediatric patients.

Focused ultrasound, the researchers hope, could revolutionize treatment for conditions from Alzheimer's to epilepsy to brain tumors -- and even help repair the devastating damage caused by stroke.

Marking a major milestone on the path to meeting the objectives of the NIH BRAIN initiative, researchers advance high-density electroencephalography (EEG) as the future paradigm for dynamic functional neuroimaging.

Researchers have used an ultrasound technique they pioneered a decade ago -- electromechanical wave imaging (EWI) -- to accurately localize atrial and ventricular cardiac arrhythmias in adult patients in a double-blinded clinical study. They evaluated the accuracy of EWI for localization of various arrhythmias in all four chambers of the heart prior to catheter ablation: the results showed that EWI correctly predicted 96% of arrhythmia locations as compared with 71% for 12-lead ECGs.

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and 'second generation' approaches are needed. Now, a team of engineers may have a way to predict which mutations will occur in people, creating an easier path to create effective pharmaceuticals.

Biological engineers have created a multitissue model that lets them study the relationships between different organs and the immune system on a microfluidic chip seeded with human cells. With this 'organs-on-a-chip' model, they could explore the role of immune cells in ulcerative colitis and other inflammatory diseases.

With the help of photolithography and programmable DNA, researchers have created a new technique that can rapidly 'print' two-dimensional arrays of cells and proteins that mimic a wide variety of cellular environments in the body. This technique could help scientists develop a better understanding of the complex cell-to-cell messaging that dictates a cell's final fate.

Ranu Jung designs neural engineering projects that drive the process of transforming basic discoveries into clinical applications. In this interview she explains how collaborative projects can at once advance the understanding of the brain and the development of medical devices.
