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. Burkitt lymphoma cells. Image courtesy of Wellcome Photo Library.

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. Calorie restriction research has a long history. In the 1930s, investigators observed that some lab rodents lived […]

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 with breast cancer, aren’t at greater risk of dying than patients with less dense breasts. Mammograms use X-rays […]

Genetic Switch Involved in Depression The activity of a single gene sets in motion some of the brain changes seen in depression, according to a new study. The finding suggests a promising target for potential therapies. Raising expression of the Gata1 gene decreases the number of neuron connections (right) compared to controls (left).

Genome Sequencing Tracks Bacterial Outbreak Last year, a deadly outbreak of antibiotic-resistant bacteria kept NIH’s Clinical Center in a state of high alert. NIH staff used genome sequencing to track the microbes’ spread, an approach that can be used to help control similar outbreaks in the future. Klebsiella pneumoniae.

Implanted Heart Cells Stifle Irregular Rhythms Heart cells derived from human stem cells can protect injured guinea pig hearts against abnormal rhythms, a new study showed. Similar heart cell transplants might one day hold promise for treating damaged human hearts. Scientists showed that transplanted human heart cells (green) could beat in sync with neighboring guinea […]

Antibodies Protect Against Range of Flu Viruses Scientists have isolated antibodies that protect mice against a variety of lethal influenza B viruses. One of them also guards against influenza A viruses. The accomplishment points the way toward universal approaches to combat all influenza A and B viruses. The flu is a contagious respiratory illness caused […]

Retinal Device Restores Sight in Mice Researchers have developed a new prosthetic technique that can restore vision to blind mice. The approach could potentially be further developed to improve sight in blind people. More than 20 million people worldwide have vision loss or blindness because of retinal degenerative diseases such as age-related macular degeneration and […]
Household Molds Linked to Childhood Asthma Three specific species of mold were more common in the homes of babies who later developed asthma. The finding highlights the importance of preventing water damage and mold growth in households with infants.
