Researchers from North Carolina State University and Duke University have developed nanoscale “patches” that can be used to sensitize targeted cell receptors, making them more responsive to signals that control cell activity. The finding holds promise for promoting healing and facilitating tissue engineering research. Read more at North Carolina State.
Researchers have long wondered what allows stem cells to persist for decades, when their progeny last for days, weeks or months before they need to be replaced. Now, a study from the University of Pennsylvania has uncovered one of the mechanisms that allow these stem cells to keep dividing in perpetuity. Read more at University of Pennsylvania.

Body piercings have been used to control wheelchairs and computers in a move scientists believe could transform the way people interact with the world after paralysis. Read more at BBCNews.com
Under a contract awarded by the National Institute of Biomedical Imaging and Bioengineering, the developers of two advanced medical terminologies have begun work to harmonize and unify terms for radiology procedures. Creating standardized radiology procedure names will improve the quality, consistency and interoperability of radiology test results in electronic medical record systems and health information exchange.

Researchers at the California Institute of Technology (Caltech) have demonstrated a method for using a lab-on-a-chip device and a cell phone to determine a concentration of molecules, such as HIV RNA molecules, in a sample. This digital approach can consistently provide accurate quantitative information despite changes in timing, temperature, and lighting conditions, a capability not previously possible using traditional measurements.

Triple-Negative breast cancer is difficult to treat because its cells are armed with molecular pumps that remove anti-cancer drugs. Former NIBIB grantee Paula Hammond, a chemical engineer at MIT, is using triple-layered chemical bombs a few billionths of a metre across to first sabotage the pumps and then deliver a poisonous payload when the cells are thus unprotected.
