A couple years ago, a team of researchers from the University of Utah managed to create a wireless network made from standard home automation devices to “see” through walls.
Now, the engineers are using the same technology to monitor breathing in patients with sleep apnea, post surgery, and babies at risk for SIDS. The system consists of Read more »

Researchers at the University of Utah and IsoForensics, Inc. in Salt Lake City have demonstrated that water can potentially be used as a tracer to determine the travel habits of individuals.
Because of the natural geographic variability in the hydrogen and oxygen isotope content of water, proteins within hair should contain evidence of these ratios and therefore act as signatures as to where someone has traveled. The current study has shown that the geographic source of tap water, bottled water, beer, and soda can be distinguished simply by measuring the isotope ratio of the water within these drinks.
In our opinion if the technology pans out for real-world use, IsoForensics has a bright future with dictatorship governments, security and intelligence services, armed forces, and maybe even some legitimate forensic causes such as war-crime investigations or even anthropology studies.

It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
Book Review: Is Empathy Learned By Faking It Till It’s Real?
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
The Spirit Of The Place: Samuel Shem’s New Book May Depress You
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
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…
