The Food and Drug Administration has proposed creating a new category of over-the-counter hearing aids that could be purchased without a test, prescription or fitting. Approximately 37 million Americans suffer from some degree of hearing loss. It can cost as much as $5,000 to go through the testing and processes to acquire a pair of doctor-ordered hearing aids.
The FDA's thinking is that increased competition will lower costs and other barriers to acquiring basic hearing aids, which are not typically covered by Medicare or other insurers.
'Alzheimer's Brain' Without Dementia
In approximately one-third of cases, patients with high levels of amyloid plaque or tau neurofibrillary tangles, both clinical criteria for diagnosing Alzheimer's disease, have no outward symptoms of dementia.
New research suggests a possible answer: a family of proteins that act as a master regulator in the brain, preventing neurons from firing out of control. Scientists boosted the activity of these proteins in mice bred to have neurodegenerative disease and report being able to save the animals' cognitive function.

While sleeping, you're still burning calories. The rate of burn depends on body weight, the amount of time you're asleep and your body temperature. On average, people burn about .42 calories an hour per pound of body weight while asleep. So for a rough hourly estimate, multiply your weight in pounds by .42.
