Chances are you know how many miles your car logs for each gallon or tankful of gas, but you probably have only a foggy idea of how much energy your house consumes, even though home energy expenditures often account for a larger share of the household budget. Strategies to close this information gap are the subject of a new...

Academic researchers have found that breathing motor vehicle emissions triggers a change in high-density lipoprotein (HDL) cholesterol, altering its cardiovascular protective qualities so that it actually contributes to clogged arteries. The finding, shown in mice, reveals how car emissions activate the early cell and tissue...

Death rates associated with patients with refractory angina, or chronic chest pain, are lower than previously considered; therefore, physicians should focus on relieving the chest pain symptoms and improving the quality of life in these patients according to an article published online this week in the European Heart Journal....

In the largest clinical trial to date to examine the efficacy of PARP inhibitor therapy in BRCA 1/2 carriers with diseases other than breast and ovarian cancer, the oral drug olaparib was found to be effective against advanced pancreatic and prostate cancers.
