A patch to help patients heal after heart attack

High blood pressure in middle age is linked to memory problems
In the past, research into the relationship between blood pressure and cognitive impairment has yielded a wide range of results—some studies found that low blood pressure was linked with memory and processing problems, others that high blood pressure was associated with these risks, and others found no correlation at all. In an attempt

Low-carb diets linked to vascular disease
Ever wonder how all that fat and protein in a low-carb diet could be good for you, even though you’re losing weight? A new study today in the journal Proceedings of the National Academy of Sciences suggests that, well, in fact, it isn’t.

It has long been common perception that people tend to meander in orbits when disoriented, and in fact, scientists

Prevention: How much can doctors and nurses really change your lifestyle choices?
A couple weeks ago I wrote about whether prevention can really cut health-care costs. Given America’s troubling chronic-disease rates, however, a more pertinent question might be this: Can health-care workers actually implement prevention on behalf of their patients?
