Research Finds Success In Small, Cheap And Strong Test For HIV And Syphilis

Researchers from Columbia University have developed a “lab on a chip” HIV and syphilis test, and are now reporting the first results from tests in the field conducted in Rwanda. The mChip, as it is called, is the size of a credit card and replicates all steps of an ELISA test, at a lower total material cost and within 20 minutes. After application of a blood sample, the chip is inserted into a $100 battery-powered handheld analyzer. It needs only 1 μl of unprocessed whole blood and does not require any user interpretation of the signal, providing a clear-cut yes or no result.

Clearly marking the shift away from abstinence-only policies, the CDC called for better, more honest and open, sex education including how to use a condom, limiting the number of sexual partners, and avoiding people who have had multiple sex partners.

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…
