As life expectancy grows, men still lagging. Duke Today, Nov. 21, 2016. Babies born in the longest-lived countries today can expect to live, on average, at least to their 80th birthday, and some will even manage to pass 100. But despite big gains in life expectancy males still lag behind females, and not just in humans but across the primate family tree.

Underfed worms program their babies to cope with famine. Duke Today, Oct. 27, 2016. Worms whose mothers didn’t get enough to eat during pregnancy cope better with famine, finds a new study of the tiny nematode Caenorhabditis elegans. The findings are consistent with a decades-old idea for humans, namely that pregnant women who don’t get enough to eat produce babies with “thrifty” metabolisms that are good at rationing nutrients and storing fat.
‘Mean girl’ meerkats can make twice as much testosterone as males. Duke Today, Oct. 20, 2016. Testosterone. It’s often lauded as the hormone that makes males bigger, bolder, stronger. Now researchers have identified one group of animals, the meerkats of Africa, in which females can produce even more testosterone than males — the only animals known to have such a pattern. Female meerkats with high levels of testosterone-related hormones are more likely to be leaders, but they also pay a price for being macho, according to two new studies.

Artificial intelligence meets big data. Duke Today, Oct. 11, 2016. Duke professor Cynthia Rudin is training computers to find patterns in crime, medical and other data that humans miss.
Apes understand that some things are all in your head. Duke Today, Oct. 6, 2016. We all know that the way someone sees the world, and the way it really is, aren’t always the same. This ability to recognize that someone’s beliefs may differ from reality has long been seen as unique to humans. But new research on chimpanzees, bonobos and orangutans suggests our primate relatives may also be able to tell when something is just in your head.

Fact-checking Senate campaign ads just got easier. Duke Today, Sept. 29, 2016. If you live in one of the battleground states in this year’s races for U.S. Senate, you have probably been inundated with political ads, many of which talk about a candidate’s willingness to toe the party line or vote across the aisle. Now, analyzing such claims for accuracy is about to get easier, thanks to a new website that lets visitors fact-check claims about congressional voting records against the data behind them.
Lemur poop could pinpoint poaching hotspots. Duke Research Blog, Sept. 22, 2016. DNA detective works aims to map the illegal pet lemur trade in Madagascar.
Analog DNA circuit does math in a test tube. Duke Today, Aug. 23, 2016. Duke University researchers have created strands of synthetic DNA that, when mixed together in a test tube in the right concentrations, form an analog circuit that can add, subtract and multiply as the molecules form and break bonds. While most DNA circuits are digital, their device performs calculations in an analog fashion by measuring the varying concentrations of specific DNA molecules directly, without requiring special circuitry to convert them to zeroes and ones first.

In the ocean, clever camouflage beats super sight. Duke Today, Aug. 23, 2016. Some fish blend seamlessly into their watery surroundings with help from their silvery reflective skin. Researchers have long assumed that squid, shrimp and other ocean animals could see through this disguise, thanks to an ability to detect a property of light — called polarization — that humans can’t see. But a new study finds that not even polarization vision helps animals spot silvery fish from afar. Picked up by Cosmos.
Is Durham’s revival pricing some longtime residents out? Duke Research Blog, Aug. 17, 2016. Durham real estate and businesses are booming. A student mapping project aims to identify the neighborhoods at risk of pricing longtime residents out. Picked up by the Durham Herald-Sun.
Of butterfly wings and caterpillar brains. Duke Today, August 8, 2016. To most people, the spectacular diversity of butterfly wing patterns is a chaotic riot of color, dots and squiggles. But to biologist Fred Nijhout, they’re variations on the same basic theme
Breakneck bite. 1,100 words, Aug. 1, 2016. The jaws of trap-jaw ants can generate forces hundreds of times their body weight and snap shut at speeds reaching 145 miles per hour — over 2,000 times faster than the blink of an eye. Duke biologists are using 3-D X-ray imaging to peer inside the insects’ heads and study the internal structures that power their impressive mandibles.
Of heartbeats, bones and brushstrokes. Duke Today, Aug. 1, 2016. It takes a well-trained eye to spot an irregular heartbeat in the peaks and valleys of an electrocardiogram. The same goes for identifying an extinct ape from a single fossilized tooth, or telling an original van Gogh from a fake. But in recent years, applied mathematician Ingrid Daubechies has been training computers to churn through ECG tracings, high-resolution scans of fossils, paintings and other complex digital data and work things out automatically.
Lemur DNA paints a picture of Madagascar’s forested past. Duke Today, July 18, 2016. While there’s no question that human activities such as logging and slash-and-burn agriculture have dramatically altered Madagascar’s forests since the first settlers arrived about 2000 years ago, just how much of the island was forested before people got there remains a matter of debate. Now, a DNA study of tree-dwelling mouse lemurs suggests that humans did not arrive to find the island as blanketed by forests as frequently assumed.

Disentangling the plant microbiome. Duke Today, July 12, 2016. With the human population expected to climb from 7.4 billion to more than 11 billion people by 2100, some scientists hope that manipulating the microbial communities in, on and around plants, the plant microbiome, could open up new ways to meet the growing demand for food. But breeding a better microbiome may be easier in some plant tissues and growing conditions than others, finds a study led by researchers at Duke University.
Taking math beyond the blackboard. Duke Research blog, July 6, 2016. Mix together 80 or so scientists and engineers from industry and academia with bottomless coffee, and stir for a week. That was the recipe for the 32nd annual Mathematical Problems in Industry Workshop held this summer at Duke.
Video privacy software lets you select what others can see. Duke Today, June 28, 2016. Camera-equipped smartphones, laptops and other devices make it possible to share ideas and images with anyone, anywhere, often in real-time. But in our cameras-everywhere culture, the risks of accidentally leaking sensitive information are growing. Computer scientists at Duke University have developed software that helps prevent inadvertent disclosure of trade secrets and other restricted information within a camera’s field of view by letting users specify what others can see.

Moving beyond race-based drugs. Duke Today, May 26, 2016. Prescribing certain medications on the basis of a patient’s race has long come under fire from those uneasy with using race as a surrogate for biology when treating disease. But there are multiple challenges to overcome before we can move beyond race-based treatment decisions, experts say.
Hijacked cell division helped fuel rise of fungi. Duke Today, May 10, 2016. The more than 90,000 known species of fungi may owe their abilities to spread and even cause disease to an ancient virus that hijacked their cell division machinery, researchers report. Over a billion years ago, a viral protein invaded the fungal genome, generating a family of proteins that now play key roles in fungal growth. The research could point to new antifungals that inhibit cell division in fungi but not in their plant or animal hosts.
Duke claims another top 10 finish in North America’s most prestigious math competition. Duke Research Blog, April 25, 2016. The Blue Devils may have lost in the Sweet 16 during March Madness 2016, but a Duke team crushed more than 500 other schools in the NCAA tournament of the math world, known by mathletes as the Putnam, claiming a top ten finish for the 22nd time since 1990.
Lemurs mix smelly secretions to make richer, longer-lasting scents. Duke Today, April 19, 2016. Humans aren’t alone in their ability to mix perfumes and colognes. Lemurs, too, get more out of their smelly secretions by combining fragrances from different scent glands to create richer, longer-lasting scents, finds a study led by Duke University.

Rough childhoods have ripple effects for wild baboons. Duke Today, April 19, 2016. Numerous studies show that childhood trauma can have far-reaching effects on adult health; new research finds the same is true for wild baboons. Baboons that experience multiple misfortunes in early life grow up to live shorter adult lives, researchers report. The results show that early adversity can have long-term negative effects even in the absence of factors commonly evoked to explain similar patterns in humans, such as smoking, drinking or medical care.

Why bearcats smell like buttered popcorn. Duke Today, April 13, 2016. The bearcat. The binturong. Whatever you call this shy, shaggy-haired creature from Southeast Asia, many people who have met one notice the same thing: it smells like a movie theater snack bar. Most describe it as hot buttered popcorn. And for good reason — the chemical compound that gives freshly made popcorn its mouthwatering smell is also the major aroma emitted by binturong pee, finds a new study.

Why testing lemur color vision is harder than it looks. Duke Research Blog, March 18, 2016. Elphaba the aye-aye is not an early riser. A nocturnal primate with oversized ears, bulging eyes and long, bony fingers, she looks like the bushy-tailed love child of a bat and an opossum. Elphaba is one of 14 aye-ayes at the Duke Lemur Center in Durham, North Carolina, where researchers have been trying to figure out if these rare lemurs can tell certain colors apart, particularly at night when aye-ayes are most active. But as their experiments show, testing an aye-aye’s eyesight is easier said than done.
