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The new 3-D model could eliminate risky trial-and-error as surgeons implant electrodes — a change akin to trading an outdated paper road atlas for a real-time GPS.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.
A section of embryonic mouse brain has been stained to show different subtypes of developing neurons. Red marks neurons born early in development and yellow are more recent; cell nuclei are blue. A team led by Debra Silver in Molecular Genetics and Microbiology has found that mice having only one good copy of the gene Rbm8a have fewer neural progenitor cells and thus fewer neurons and are born with smaller brains, demonstrating that Rbmb8a is crucial to healthy brain development.
The combination of an old malaria drug, chloroquine, and an experimental drug, D4476, has been found to interrupt the normal functions of cancer cells, stained blue. David Virshup and Jit Kong Cheong, from Duke-NUS Graduate Medical School in Singapore, wanted to interfere with the cancer cell's known reliance on autophagy, a form of self-destruction. The cells ended up with their surfaces clogged with digestive vacuoles (red), that effectively prevent them from obtaining nutrition.
The colored dots and swirls of "dust" in this tornado-shaped diagram represent thousands of chemical compounds grouped by their physical and chemical similarities in a new technique called "materials cartography," by Stefano Curtarolo, a professor of material sciences and physics and PhD student Corey Oses.
