Life today exists as cells, which are sacs packed with DNA, RNA, proteins and other molecules. But when life arose roughly four billion years ago, cells were far simpler. Some scientists have ...

Billions of our cells die every day to make way for the growth of new ones. Most of these goners are cleaned up by phagocytes—mobile immune cells that migrate where needed to engulf problematic ...

For years, Amanda Smith and her husband were jolted awake at night by a buzz-buzz-beep — an alarm warning that her blood sugar was too high or too low. She would reach for juice boxes stored in ...

With research still ongoing, using stem cell hair transplants as a way to regenerate hair growth looks promising. The procedure, however, is not yet FDA approved. A stem cell hair transplant is ...

According to many experts, we may soon find ourselves using fuel cells to generate electrical power for all sorts of objects we use every day. A fuel cell is a device that uses a source of fuel ...

From the first in-car phones of the 1940s to the best smartphones of today, the evolution of cell phones is nothing short of remarkable. To that end, let’s look at the history of cell phones.
