Although the snooze button may seem like a gift from the Almighty on Monday mornings, sleep experts agree that hitting the snooze button contributes to a tired morning and doesn't help you feel more rested.
Researchers have developed a wireless device the width of a human hair that can be implanted in the brain and activated by remote control to deliver drugs. The device contains microfluid channels and microscale pumps, but is as soft as a brain tissue and can function for a long time without causing inflammation or neural damage.
A typical person contains only about 37 trillion human cells. In other words, bacteria might outnumber human cells in an average person by roughly three to one.
Don't worry about being less than human, though. Bacterial cells are very small. All of these bugs make up only between 1 and 3 percent of your body weight.
