The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The ancient monkey, known as Victoriapithecus, first made headlines in 1997 when its 15 million-year-old skull was discovered on an island in Kenya’s Lake Victoria. Now, thanks to X-ray imaging, researchers have peered inside its cranial cavity and created a three-dimensional computer model of what the animal’s brain looked like.
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.
The achievement gap between white children and those of color in our nation’s schools has profound repercussions for families and communities. But consider as well what it means to us collectively:
DURHAM, N.C. -- As investigators look into the massive data breach at the federal Office of Personnel Management, most chief financial officers around the world say their companies also have been hacked, new research finds. The problem is worse at small and medium-size firms because they dedicate fewer resources to preventing data breaches.
These are some of the findings from the latest Duke University/CFO Magazine Global Business Outlook Survey, which ended today.
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The new 3-D model could eliminate risky trial-and-error as surgeons implant electrodes — a change akin to trading an outdated paper road atlas for a real-time GPS.

A startup company based on technology invented at Duke University is working to make blood glucose measurement as easy as exhalation—and end the need to draw blood.
The idea is the brainchild of Ryan McCormick, a recent PhD graduate from Duke’s Department of Computer and Electrical Engineering (ECE), who spent the past five years working on the underlying technology as his thesis.
In the past 15 years, metamaterials have brought breakthroughs like invisibility cloaks, acoustic cloaks, miniaturized flat antennas, and you-don’t-have-to-stop-anymore airport security screenings. During Spring term 2015, Sir John Pendry of Imperial College London visited co-founder of the field David R.
In the mid-2000s, Pinar Yoldas spent three years at UCLA pursuing an M.F.A. in design and media arts. While there, her typical trek to campus was an hour-long bike ride from East Hollywood to Westwood along Santa Monica Boulevard.
“Every time I did this, I was literally inhaling the smog,” says Yoldas, a Ph.D. candidate in art, art history, and visual studies at Duke. “I kept thinking about this and ways to protect myself, and being angry at car drivers.”
The "fight or flight" response blamed for some of our modern ills was a great thing, back in the day.
This automatic physiological response to stress pumps the hormone cortisol through your veins, rapidly shutting down your immune system and redirecting resources to your muscles and brain to give you the extra energy to fight or outrun the unseen threat.
It surely enabled our ancestors to hunt their dinners without becoming dinner themselves.
