the body works to limit blood loss by reducing the amount of blood flowing to the wounded area. Proteins in blood, such as fibrin, work with the blood platelets already in place and plasma to form a protective covering called ascab. While your skin regenerates underneath the protective layer...
Sentinels often use their powerful, rock-plated wings to create a downdraft wingblast. These blasts are strong enough to knock dragons out off the air and slow down falling dragons enough for them not to die or break bones on impact with the ground. This ability can also be used by other...
Once a mother gives birth, the umbilical cord and remaining blood are often discarded. However, this blood also contains stem cells from the fetus. Umbilical cord blood can be harvested and the embryonic stem cells grown in culture. Unlike embryonic stem cells from earlier in development, fetal ...
At 18, Katie Stubblefield lost her face. At 21, she became the youngest person in the U.S. to undergo the still experimental surgery. Follow her incredible story.
While we’ve been made to think the only way to avoid cavities is to reduce sugar and brush our teeth, the research points to many more dietary causes. And dental interventions aren’t the only answer when it comes to trying to heal decay. Some time and patience, along with great oral...
This is a chronic (ongoing) condition that often begins in childhood. Your skin becomes very itchy, leading to scratching. Scratching leads to cracked, red, crusty skin that sometimes oozes a clear fluid. No one knows what causes eczema, but scientists do know that your genes, immune system...
Thus, it is no wonder that the Doctor is rarely excited to regenerate and often tries to delay the process as much as they can. In Season 4’s “Journey’s End”, the Tenth Doctor even managed to stop an already initiated regeneration process by shooting the concentrated energy into a bi...
These folks are also often overweight and sedentary. So does meat give you cancer? Or do you get it from being fat and lazy? The answer is almost certainly the latter, meaning that if you’re fit and work out regularly, a modest serving (about 4 ounces) a few times a week of beef...
own bone, synthetic bone, or donated bone to replace bone destroyed by your gum disease. Grafts serve as a platform for the regrowth of bone, which restores stability to your teeth. New technology, called tissue engineering, encourages your body to regenerate bone and tissue at a faster rate...
patient's bones. The donor bone marrow cells differentiate into blood cells that the patient needs. Often, the patient must take drugs to prevent his or her immune system from rejecting the new bone marrow. But this procedure uses existing hemopoietic stem cells. How would you use stem cell ...
