Internal brain timers linked with motivation and behavior
Time can be measured in many ways: a watch, a sundial, or the body’s natural circadian rhythms. But what about the sexual behavior of a fruit fly? “If you ask a bunch of scientists whether animals can keep time, many would say they cannot, that things happen over time—but time itself is not measured,” says ...

Unlocking a treatment for diffuse intrinsic pontine glioma
Diffuse intrinsic pontine glioma (DIPG) is a highly aggressive and one of the most difficult-to-treat childhood tumors. It’s the second most common malignant brain tumor, as well as the leading cause of brain tumor death among children. “It’s essentially 100 percent fatal,” says Katherine Warren, MD, clinical director for Pediatric Neuro-Oncology at Dana-Farber/Boston Children’s Cancer and ...

Low enrollment stymies completion of rare disease clinical trials
Rare diseases are anything but rare when taken together. In the United States alone, they affect nearly 30 million people. Yet clinical trials for rare diseases are frequently incomplete or go unpublished in the medical literature, finds a study published today in the journal PLOS Medicine. Analyzing 659 trials, researchers at Boston Children’s Hospital found ... Read More about Low enrollment stymies completion of rare disease clinical trials
‘Face blindness’ may represent a failed brain network — and could shed light on autism
People with prosopagnosia, or “face blindness,” have trouble recognizing faces — even those of close friends and family members. While some people can compensate by using clothing and other cues, face blindness often creates serious social problems. It often becomes apparent in early childhood, but, rarely, people can acquire face blindness later in life after ...

Healing hearts under a watchful eye
Cardiac surgery is performed using visual landmarks inside the heart. There are specialized conduction tissues that run underneath the surface, which are important for the heart’s rhythmic beating. Cardiac surgeons operate with these landmarks in mind to avoid injury to conduction tissue, but locating these tissues can be challenging. Fiberoptic confocal microscopy technology inside the ...

Diet trials often amend their outcome measures as they go
Ever wonder why science can’t settle simple diet-related questions? In part it’s because most clinical trials involving diet, even those published in good journals, lack the rigor of most drug trials. They’re often small, of short duration, and unable to rigorously control subjects’ adherence to the test diets. Moreover, a study published today in JAMA ...

Boosting host immune defenses to treat tuberculosis
Current treatment regimens for Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, are long, complex, and hard for people to sustain. Moreover, the bacteria often develop drug resistance, and many people harbor multi-drug-resistant strains. In 2018 alone, nearly 1.5 million people died from tuberculosis worldwide. Now, a study in iScience suggests a new approach that ... Read More about Boosting host immune defenses to treat tuberculosis
Unlocking antibody diversity: chromatin loops, V(D)J recombination, and class switching
A new study from the laboratory of Frederick Alt, PhD, of the Program in Cellular and Molecular Medicine (PCMM) at Boston Children’s Hospital reveals yet another way in which chromatin regulation — changing the configuration of our DNA and its packaging — enables our immune systems to produce its wide-ranging arsenal of antibodies. In September in the ... Read More about Unlocking antibody diversity: chromatin loops, V(D)J recombination, and class switching
CHIP-ing away at health and medicine for 25 years: A look back
In 1994, when CHIP was formed, the dotcom boom was just dawning. iPhones and social media (except for the earliest versions) were more than a decade away. Bill Clinton was president. Isaac Kohane, MD, PhD, had just completed a fellowship in endocrinology at Boston Children’s Hospital under the mentorship of Joseph Majzoub, MD. He wanted ...

Two neuroscience rock stars elected to the National Academy of Medicine
Beth Stevens, PhD, and Elizabeth Engle, MD, are the latest Boston Children’s Hospital researchers to be elected to the prestigious National Academy of Medicine. Their election, together with Daphne Haas-Kogan, MD, brings Boston Children’s total number of current NAM members to 22. Both scientists hail from the F.M. Kirby Neurobiology Center at Boston Children’s and are ... Read More about Two neuroscience rock stars elected to the National Academy of Medicine
