In 2011, there were 230,480 new breast cancer cases and 39,520 deaths attributed to the disease, according to the American Cancer Society. Many women get diagnosed with breast cancer after symptoms appear, while others may find something suspicious during a mammogram or screening exam. A new bra in development aims to predict if a woman is developing abnormal breast tissue earlier and more accurately than existing methods can.
People who consistently get too little sleep face bigger concerns than daytime fatigue and crankiness. Over the long term, sleep deprivation also increases the risk of serious health problems including obesity and type II diabetes. Scientists have come up with a number of plausible explanations for this increased risk. Various studies have shown, for instance, that how much we sleep can affect blood sugar levels, hormones that control appetite, and even the brain’s perception of high-calorie foods. A small new study, published Monday in the Annals of Internal Medicine, adds a key piece to the puzzle by drilling down to the cellular level: Sleep deprivation, the study found, impairs the ability of fat cells to respond to insulin, a hormone that regulates metabolism and is involved in diabetes.
