 Aspirin May Extend Lifespan for Cancer Patients: Colorectal cancer patients may benefit from aspirin therapy, according to a report published in the New England Journal of Medicine. The Dana-Farber Cancer Institute conducted a study of over 900 colorectal cancer patients. Researchers discovered that patients whose tumors had the gene PIK3CA were successful with aspirin therapy. 97 percent of these patients had survived five years after the diagnosis, compared to the 74 percent who did not take aspirin. Colorectal cancer is the second leading cause of cancer-related deaths in the United States, according to the Center for Disease Control and Prevention. This is the first time where doctors have a genetic marker to determine which colorectal cancers respond to a specific therapy.

New Use for Wine Leftovers: A new study suggests the leftover seeds and skins from winemaking are high in antioxidants and can be used to fortify other foods. Researchers discovered the pomace from pinot noir and merlot wines have the highest amount of antioxidant dietary fiber. To convert the pomace into a usable form, the researchers dry the pomace in an oven, then air dry it. This process is less expensive than freeze drying and can be used to dry large quantities of wine  processing byproducts. According to the researchers, pinot noir and merlot antioxidant dietary fibers can be incorporated into other foods for added health benefits.

Exercise Preserves Your Brain: We’re all aware of the benefits of exercise, but a new study says remaining physically active may prevent your brain from shrinking as you get older. Exercise protects your thinking and memory skills, something we definitely don’t want to lose as we age. Researchers at the University of Edinburgh followed over 600 people at the age of 70 and checked in three years later. The scientists found that those who exercised the most had less damage in the brain’s white matter, the foundation of the brain’s communication system. Doctors agree that exercise at any age is important to keep your brain healthy.
