CPR: It's not always a lifesaver, but it plays one on TV
If you think that performing CPR on a person whose heart has stopped is a surefire way to save their life, you may be watching too much TV. The truth is more depressing than fiction, according to a new study. While medical dramas Grey's Anatomy and House show cardiopulmonary resuscitation saving a patient's life nearly 70 percent of the time, the real immediate survival rate is nearly half that -- around 37 percent.
New synthetic tumor environments make cancer research more realistic
Tumors are notoriously difficult to study in their natural habitat -- body tissues -- but a new synthetic tissue environment may give cancer researchers the next-best look at tumor growth and behavior. Researchers have now developed a new technique to create a cell habitat of hydrogels which can realistically and quickly recreate microenvironments found across biology.
