Fertility is a priority for many young women with breast cancer, yet new research has found many have little knowledge about fertility issues, leading to confusion and conflict around planning for a family.

Young black athletes with sickle cell trait might be susceptible to sudden death
The sickle cell trait could be a cause -- albeit rare -- of sudden death in young African-American competitive athletes, most commonly during football training, according to a scientific poster that will be presented at the American College of Cardiology Scientific Sessions, April 1-3, in New Orleans.

Scientists at the Dana Farber Cancer Institute have identified a mutation in the DDR2 gene that may indicate which patients with squamous cell lung cancer will respond to dasatinib.

Self-cooling observed in graphene electronics
With the first observation of thermoelectric effects at graphene contacts, University of Illinois researchers found that graphene transistors have a nanoscale cooling effect that reduces their temperature.

New strategy for stimulating neurogenesis may lead to drugs to improve cognition and mood
Researchers at Columbia University Medical Center have developed a new way to stimulate neuron production in the adult mouse brain, demonstrating that neurons acquired in the brain's hippocampus during adulthood improve certain cognitive functions.

New evidence from cardiac researchers at the Intermountain Medical Center Heart Institute in Utah demonstrates that routine periodic fasting is also good for your health, and your heart.

Hypothermia proves successful in younger cardiac patients too
Young adult patients with genetic heart diseases, such as hypertrophic cardiomyopathy (HCM), substantially benefitted from therapeutic hypothermia, which could further extend the role for this treatment strategy in new patient populations, according to a scientific presentation at the American College of Cardiology (ACC) Scientific Sessions in New Orleans, April 1-3.

Researchers at the Hebrew University of Jerusalem have achieved a breakthrough in the field of nanoscience by successfully altering nanocrystal properties with impurity atoms -- a process called doping -- thereby opening the way for the manufacture of improved semiconductor nanocrystals.

Vitamin D levels linked with health of blood vessels
A lack of vitamin D, even in generally healthy people, is linked with stiffer arteries and an inability of blood vessels to relax, researchers have found.
