Cambridge, Massachusetts - Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.

Austin, Texas - Scientists have discovered a new way to manipulate how cells function, a finding that might help advance an experimental approach to improving public health: DNA vaccines, which could be more efficient, less expensive and easier to store than traditional vaccines.

Baltimore, Maryland - Those who possess a low sense of purpose in life are more likely to die or have heart attacks or strokes.

Dallas, Texas - Going home from the hospital doesn’t mean leaving behind the healthcare and technology that can help in heart disease and stroke recovery, thanks to a new American Heart Association initiative. Connected Heart Health™ extends research-proven care beyond the healthcare setting by giving people information and resources to better manage their care themselves.

Baltimore, Maryland - People with poor physical fitness in their 40s may have lower brain volumes by the time they hit 60, an indicator of accelerated brain aging, according to new research presented at the American Heart Association EPI/Lifestyle 2015 meeting.

Atlanta, Georgia - A new American Cancer Society study finds that the use of adjuvant systemic therapy for localized gastrointestinal stromal tumors (GISTs ) has significantly increased over time and that patients treated with the therapy have better survival than those treated with surgery alone. The study, which appears early online in the American Journal of Clinical Oncology, also finds that older patients and minorities are less likely to receive adjuvant therapy for GISTs.
