Finding Treasure in “Junk” DNA
A vast consortium of researchers has created a view of the human genome that extends well beyond our genes. In a related study, a systematic analysis linked regulatory regions to disease.
Comparing Treatments for Lacunar Stroke
Aspirin combined with clopidogrel is no better than aspirin alone for preventing stroke in people with a history of lacunar strokes, according to a new study. The combination also carries a greater risk of gastrointestinal bleeding.
MRI Shows Promise for Heart Procedures
An experimental MRI method may be as safe and swift as standard X-ray procedures for guiding surgical interventions in the heart. The finding might one day offer a radiation-free alternative to X-rays for some heart procedures.

Calorie Restriction May Not Extend Life
In a 23-year study, scientists found that significantly cutting calories didn't extend the lives of rhesus monkeys. The result differs from previous work that linked calorie restriction to longer life in primates.
Study Suggests New Approaches to Burkitt Lymphoma
A new study revealed insights into how Burkitt lymphoma differs from other lymphomas. The researchers identified several cancer-related genes and pathways that could serve as targets for future treatments.
New Brain Cleaning System Discovered
Scientists have discovered a system that drains waste products from the brain. The finding may reveal new ways to treat neurodegenerative disorders like Alzheimer's disease.

After Cancer Diagnosis, Breast Density May Not Matter
Women with breasts that look dense on a mammogram have a higher risk of developing breast cancer. But a new study found that most of these women, once diagnosed, aren't at greater risk of dying than patients with less dense breasts.
Genetic Switch Involved in Depression
The activity of a single gene sets in motion some of the brain changes seen in depression, a new study revealed. The finding suggests a promising target for potential therapies.
Genome Sequencing Tracks Bacterial Outbreak
Staff used genome sequencing to track a deadly outbreak of antibiotic-resistant bacteria at NIH's Clinical Center. The approach can be used to control similar outbreaks in the future.
