Most of the time in the global health research field, a long time has to pass before we see any tangible outcomes in people’s daily lives and health. Years can easily go by between the start of a research project, the fieldwork, the sampling, processing of samples, analyzing the data, writing and publishing until you see the real public health payoff.
A $20 million grant from the Bill & Melinda Gates Foundation will help the Duke Global Health Institute (DGHI) educate a new generation of leaders and experts, and build research capacity from Durham to Delhi to address critical global health challenges.
DURHAM, NC - Looking around at a 20th high school reunion, you might notice something puzzling about your classmates. Although they were all born within months of each other, these 38-year-olds appear to be aging at different rates.
Indeed they are, say the leaders of a large long-term human health study in New Zealand that has sought clues to the aging process in young adults.
SINGAPORE, 3 July 2015 – One more piece and we are done! A research team led by the Duke-NUS Graduate Medical School Singapore (Duke-NUS) has found the second-to-last piece of the puzzle needed to potentially cure or treat dengue. This is welcome news as the dengue virus infects about 400 million people worldwide annually, and there is currently no licensed vaccine available to treat it.
DURHAM, N.C. – Researchers at Duke University School of Medicine and Brigham and Women’s Hospital, Harvard Medical School have identified a mechanism that explains why some mutations can be disease-causing in one genome but benign in another.
This composite image from the lab of Scott Soderling in Cell Biology shows both the behavior and structure of a protein called WRP that occurs almost exclusively in neurons. Tagged green, the protein homes in on slender, red-labeled dendrites on the receiving end of a neuron. A computer-rendered model at the center of the image shows the structure of the portion of WRP that binds to the surface of the dendrite.
For the past 17 years, neurosurgeons have implanted electrodes into the brains of persons with Parkinson’s disease to deliver a constant barrage of electric impulses. For many patients, the treatment known as Deep Brain Stimulation (DBS) immediately relieves the motor impairment caused by the disease.
Unfortunately, nobody really knows why.
An international team of scientists led by Duke University researchers has uncovered key structural differences in the brains of parrots that may explain the birds' unparalleled ability to imitate sounds and human speech.
Reported June 24 in Plos One, these brain structures had gone unrecognized in studies published over the last 34 years. The results also may lend insight into the neural mechanisms of human speech.
The saying "what doesn't kill you makes you stronger" may not hold up to scientific scrutiny.
After the plains of southern Kenya experienced a severe drought in 2009 that took a terrible toll on wildlife, researchers looked at how 50 wild baboons coped with the drought, and whether the conditions they faced in infancy played a role.
The semi-arid savanna of southern Kenya usually receives an average of 14 inches of rain a year--akin to much of Nebraska or Kansas--but in 2009 it fell to five inches, less than the Mojave Desert.
DURHAM, N.C. – Scientists at Duke Medicine have produced a 3-D map of the human brain stem at an unprecedented level of detail using MRI technology.
In a study to be published June 3 in Human Brain Mapping, the researchers unveil an ultra high-resolution brain stem model that could better guide brain surgeons treating conditions such as tremors and Parkinson’s disease with deep brain stimulation (DBS).
The new 3-D model could eliminate risky trial-and-error as surgeons implant electrodes — a change akin to trading an outdated paper road atlas for a real-time GPS.
