A debate is on over the benefits of taking aspirin for those without a history of prior cardiovascular disease. The current thinking advocates using low-dose aspirin, for primary prevention, in certain high risk groups: those with advanced age, diabetes, high cholesterol, high blood pressure and smoking.

Besides the hundreds of millions that will be paid by the NFL to former, injured players, there's a different public-health initiative involving football that's also worthy of attention.

18% attrition is a waste of our teaching resources and creates unwarranted stress for our physicians in training.

As if the starfish itself wasn't beautiful enough, now we have new research from Stanford University's School of Engineering revealing the beauty and wonderous efficiency of how this fascinating, five-pointed creature survives and grows in the sea.

Pandas are picky creatures. Now, it appears that pandas have yet another quirk: minimum area requirements. A new study published in Scientific Reports shows that they prefer about 115 square kilometers (44 square miles) of space. Even though smaller areas of habitat are available, pandas are less likely to live there.
