Disease Detected In Exhaled Breath?

A new sensor developed at Stony Brook University may become a clinically useful tool for detecting disease biomarkers in breath. The nanoprobe-based technology is currently able to detect acetone, but should be modifiable to spot other compounds.

From the study abstract:

This paper describes a sensor nanotechnology suitable for non-invasive monitoring of a signaling gas, such as acetone, in exhaled breath. This is a nanomedicine tool comprised of a selective acetone nanoprobe working on the principle of ferroelectric poling sensing, and a microelectronics circuit for comparing the actual sensor signal to a predetermined threshold value, displaying the result using LED signals. This on/off type non-invasive diagnostics platform technology is based on nanotechnology, gives a fast response, it is simple to operate and inexpensive to manufacture, and may truly revolutionize personalized medicine.

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
