A groundbreaking brain imaging study from Wake Forest University School of Medicine confirms a vital step toward new Alzheimer’s disease treatments: Intranasal insulin, delivered via a simple nasal spray, safely and effectively reaches key memory regions of the brain in older adults. The study also revealed that people with early cognitive decline absorb it differently.

Although lithium is highly effective in treating bipolar disorder, the chemical has a narrow therapeutic window—too high a dose can be toxic to patients, causing kidney damage, thyroid damage, or even death, while too low a dose renders the treatment ineffective.

Flossing your teeth at least once a day is an essential part of any oral health routine. But it might also one day protect other parts of the body as scientists have created a novel, needle-free vaccine approach using a specialized type of floss.
