Diamonds deliver best nanomedicine
NORTHWESTERN (US)—Gene therapy holds promise in treating a myriad of diseases, including cancer, heart disease, and diabetes. Developing a scalable system for delivering genes to cells both efficiently and safely, however, has been a challenge. (more…)

Blame the metal, not the nanotubes
Metal catalysts used to create carbon nanotubes can block a key signaling pathway in neurons. Experiments show the metal particles tend to plug cellular pores normally reserved for calcium ions. (Credit: Lorin Jakubek/Brown University)

Black patients seen, not heard
“There are several possible reasons why [black patients] may talk less to their physicians. They might not trust the physician or feel that they are ‘disconnected’ from their doctors, for whatever reasons,” says lead author Crystal Wiley Cené.

Nanoalerts from healthy cells signal cancer
Vadim Backman, the study’s senior author, says nanoscale changes in both cancer cells and normal cells far away from the tumor site “are general phenomena in carcinogenesis and occur early in the process.”

Hands-on relief from carpal tunnel syndrome
In a five-minute test, a doctor uses pegs to isolate a patient’s individual fingers. A loop is fitted around the finger, and when the patient moves it, the amount of force generated is measured. “PRIME gets the peak force,” says co-developer Shuai Xu, allowing the doctor to create a patient-specific file.

Detector spots respiratory infections much earlier
Vanderbilt University researchers David Wright (right) and Frederick Haselton (left) have developed a new detection method that can catch respiratory infections at a very early stage. The system “could easily be packaged in a disposable device about the size of a ballpoint pen,” says Haselton. (Credit Steve Green/Vanderbilt university)

Engineered silicone reborn as medical cure
UC IRVINE (US)—What’s the connection between solar cells and urinary tract disorders? Research by Frank Shi. His team at the University of California, Irvine developed a specially formulated silicone for use in optical electronics. New findings suggest the substance could play a double role, revolutionizing treatment of urinary tract diseases. (more…)
