Discovery of chromosome-capping activator could aid cancer research

Researchers at Princeton University discovered a new activator protein Est1 that plays a key role in telomere capping. This finding contradicts existing theories and may offer a new target for cancer treatment. Est1 works by sweeping in with precise timing to activate the telomere-building process.

Obesity might play part in increasing breast cancer rates among Hispanics

A study by researchers at the University of Southern California found that obesity and weight gain in Hispanic women are associated with a nearly two-fold increased risk of breast cancer. The risk was elevated regardless of menopausal status, and particularly among those who gained substantial weight after age 18.

Cooking sweet corn boosts disease-fighting nutrients

Research at Cornell University found that cooking sweet corn increases its antioxidant activity by up to 53% and ferulic acid content by 900%. This boost is due to the release of bound ferulic acid during high-temperature cooking.
