The Merck Manual, a New York Times best seller that has sold more than 4 million copies worldwide, is one of those medical tomes you don't typically find in a layperson's home library. It's big, heavy, not terribly exciting, and like most physicians' desk references, not the cheapest book around.

Not to be outdone by the competition, Merck & Co. released a new edition Thursday, called The Merck Manual Home Health Handbook (3rd edition). Because the book is still big, heavy, not terribly exciting, and not terribly cheap, Merck has released its contents as an iPhone app as well (home edition: $9.99; professional edition: $29.99), thereby solving its problems of size, weight, cost, and yes, even excitement, as the app has way more going on than its old-fashioned counterpart.… Read more

If we're honest, most of us are either snorers or sleeping next to one.

On a recent camping trip, I woke up in the middle of the night thinking we had a bear grunting just outside our tent; heart racing, I turned on my head lamp to investigate. Turns out my husband, who rarely snores, sounds like a bear when he does. I tossed and turned for an hour until finally shaking him awake to shut him up.

For couples dealing with this kind of sleep disruption on a regular basis, it's probably not a stretch to say … Read more

This week the Annals of Improbable Research hosted its 19th First Annual Ig Nobel Prize Ceremony. As CNET News' Elinor Mills wrote, this year was no less ignoble than the previous 18, with such delightful discoveries as applications for panda poo and observations from a lifetime of knuckle cracking.

Except for one award: the gas mask bra, which, while ridiculous and hilarious at face value, has far more going on below the, er, neckline.

Elena Bodnar, who lives in Chicago, got her start as a scientist in Ukraine, when she witnessed the devastating effects of the Chernobyl nuclear plant disaster … Read more

Every year, some 16,000 babies in the U.S. experience loss of vision due to retinopathy of prematurity (RoP), with 400 to 600 becoming legally blind, according to the National Eye Institute. When babies are born prematurely, their retinal blood vessels don't always develop fully, and the abnormal vessels are more prone to leaking and contracting. If that causes the retina to detach, babies can lose some or all vision.

A new handheld device, developed in part by biomedical engineers at Duke University Medical Center, uses something called spectral domain optical coherence tomography (SD OCT) to create a 3D image of the back of the eye.

Duke Eye Center ophthalmologist Cynthia Toth compares the process to inspecting fish from the side of an aquarium instead of through an ocean's murky surface; the 3D high-resolution map reveals the retina's layers in intricate detail "at almost the cellular level," she says.… Read more

For The Wall Street Journal's ninth annual technology innovation awards, editor Michael Totty reviewed nearly 500 entries and, with a team of judges, weighed which of the top 180 were the most groundbreaking and which were most likely to prove useful during economic hardship. The top two awards both went to medical technologies, besting energy-efficient next-generation LEDs and paper-thin flexible speakers. Affordable health tech seems to have impressed the judges as its own sort of innovation.

The gold award went to the Ibis T5000, a sensor developed by Abbott Laboratories and its Ibis Biosciences unit that can quickly detect … Read more

A 67-year-old man who has suffered from Parkinson's disease since his early 40s has become the first person in the world to be implanted with the Brio neurostimulator, which St. Jude Medical says has just earned CE Mark approval (CE stands for Conformite Europeenne).

Weighing in at just 1 ounce and measuring a mere 10 millimeters thick, the Brio is the smallest, longest-lasting rechargeable deep brain stimulator (DBS) that aims to treat the symptoms of Parkinson's in the world, according to its creator. One battery is supposed to survive a decade of recharging.

"Deep brain stimulation therapy … Read more

Breath might be tested to measure more than sobriety if researchers at the Russell Berrie Nanotechnology Institute in Haifa, Israel, have anything to say. They've developed a sensor made from gold nanoparticles that is able to distinguish between the breath of those with lung cancer from those without.

The sensing technology, according to lead author Hossam Haick, does not require the exhalation to be pre-treated in any way; the resulting breath test is simple, affordable, and portable. (In existing tests, preconcentration of the biomarkers is required to improve detection.)

"We demonstrated that our device has a potential not … Read more

Somewhere between one-third and one-half of all Americans take their medication at the wrong time, or at the wrong dosage, or simply forget altogether, according to a New England Healthcare Institute study released earlier this month (PDF).

MedMinder Systems to the rescue. The wisely named Newton, Mass.-based start-up is one of several companies working to develop the ultimate smart pillbox. Approximately the size of a textbook, "Maya" (the wisdom behind the box's nickname remains elusive) holds 28 small plastic cups that can be designated separately for different pill types and detailed regimens.

When a pill is … Read more

That ubiquitous symbol of the medical profession, the stethoscope, is finally undergoing a 21st century tech makeover. The next time you drop by the doctor's, his acoustic listening implement may well sport Bluetooth connectivity and an LCD panel.

3M Health Care has announced the Littmann Electronic Stethoscope, which packs features most headphone users would be familiar with, such as noise cancellation and greater sound clarity.

With the souped-up hearing, the Littman then transmits lung, heart, and body sounds wirelessly to the bundled Zargis StethAssist program for further analysis, as well as to keep a record on file. Which is … Read more
