Contact Lenses That Darken In Bright Light

Researchers have been trying to coat contact lenses with light sensitive dyes to have them turn dark during bright lighting conditions. Glasses with this property have existed for decades, but the same coating methods are not applicable to contacts.

Technology Review reports on work by the Institute for Bioengineering and Nanotechnology (IBN) in Singapore to use the entire volume of the lens to contain the dye: Read more »

MD Seniority Determined By Pocket Content?

Long, long ago, when I was a medical student, we joked that you could tell how senior a physician was by how much junk was in their lab coat pockets.  As students, we tended to carry around big bags full of every medical gadget we could think of, plus a few reference texts.  The attendings were slim and graceful in their long white coats with empty pockets.

When I became an intern and moved into the hospital full-time, all that crap became just too much to lug around.  I ditched the bag, and my short white coat (with interior pockets, thank god) became loaded down with tons of stuff: reflex hammers, pocket reference guides, photocopied research papers for reading, patient lists, a procedure log, a PDA with epocrates, a bit of a snack maybe, and more.  The coat weighed at least ten pounds fully loaded.  As a junior resident, I pared it down to the few references and gadgets I actually used frequently, and the coat got a lot lighter.  With each succeeding year I have lightened the load somewhat, down to the absolute essentials.  I shed the white coat years and years ago.  Now the only things I bring with me to the hospital are:


Three items.  It’s very liberating.  Of course, I have epocrates and more on every computer workstation, so the references are there in the ER for me, but still, it’s something of a victory over inanimate junk and my own packrat tendencies that I can go to work with only three things in my pockets.

The downside is that if I happen to forget any one of these three sacred totems, it totally ruins my whole day.

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…
