CPR: It's not always a lifesaver, but it plays one on TV

Science News Daily - August 28, 2015 - 12:52pm
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

Science News Daily - August 28, 2015 - 12:52pm
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.

Important steps toward developing a blood test to catch pancreatic cancer early

Science News Daily - August 28, 2015 - 9:23am
Pancreatic cancer is the fourth most common cause of cancer-related death in the United States and has a 5-year survival rate of only 6 percent, which is the lowest rate of all types of cancer.  This low survival rate is partially attributed to the difficulty in detecting pancreatic cancer at an early stage.

New embryo image processing technology could assist in IVF implantation success rates

Science News Daily - August 28, 2015 - 9:23am
Biologists and engineers have developed a new non-invasive image processing technique to visualize embryo formation. Researchers were able to see, for the first time, the movement of all of the cells in living mammalian embryos as they develop under the microscope. This breakthrough has important implications for IVF treatments and pre-implantation genetic diagnosis. In the future, this approach could help with embryo selection to improve IVF success rates.

Lack of folic acid enrichment in Europe causes mortality among fetuses

Science News Daily - August 28, 2015 - 9:22am
A new international study shows that 5,000 fetuses in Europe annually are affected by spina bifida and other severe defects on the central nervous system. Seventy percent of these pregnancies are terminated, while increased mortality and serious diseases affect the children who are born. At least half of the cases can be avoided by adding folic acid to staple foods as is already being done in 70 non-European countries.
