New method for counting tumor-fighting cells to predict ovarian cancer

One way to predict survival of many types of cancer is by counting the number of tumor-attacking immune cells that have migrated into the tumor in an effort to eradicate it - a sign of the body's immune response to the cancer. However, quantifying these armies of immune cells has been difficult - until now.

White House advances positive messages to defend health law, urges Americans to enroll

President Obama on Tuesday embarked on the difficult task of persuading Americans to reconsider his landmark health-care law after its botched launch, imploring people to sign up as part of a major push to publicize the benefits of the Affordable Care Act. Republicans immediately lampooned the effort - coming more than three years after passage of the law and two months after its disastrous rollout - and conservative activists vowed to wage a counterassault publicizing the law's downsides (Goldfarb and Eilperin, 12/3).

Tongue twisters can open windows into the brain's speech-planning processes

Tongue twisters are not just fun to say; it turns out that these sound-related slip-ups can also open windows into the brain's speech-planning processes. A team from the Massachusetts Institute of Technology (MIT) will report new insights gleaned from a comparison of two types of tongue twisters at the 166th meeting of the Acoustical Society of America (ASA), held Dec. 2-6, 2013, in San Francisco, Calif
