DURHAM, N.C. – Special diets, exercise programs, supplements and vitamins -- everywhere we look there is something supposed to help us live longer. Maybe those work: human average life expectancy has gone from a meager 40-ish years to a whopping 70-something since 1850. Does this mean we are slowing down death?
A new study comparing data from nine human populations and 30 populations of non-human primates says that we are probably not cheating the reaper. The researchers say the increase in human life expectancy is more… read more about Sweeping Analysis Concludes There’s No Cheating Old Age »
Biology. A discipline full of wonder, discovery, fancy equipment, gorgeous field sites, charismatic organisms, and jargon. Lots of jargon.
So much jargon that it is sometimes hard to decipher who studies what. Enter BioGist, Duke Biology’s new podcast, which gives you just the gist of what our amazing faculty study, how they study it, and why. It also gives you a little glimpse of how cool they are when they are not hard at work (yes, faculty have real lives outside of work).
BioGist is made by undergrads for undergrads… read more about BioGist, our new Podcast! »

What do choirs, orchestras, bands, dancers, and athletes all have in common?
If you answered they are all performers in their respective fields, you’d be correct. And what do performers do before they go on stage or take the field?
They warm up, to help ensure that when it’s their time to shine, they perform at their best.
Duke University researchers have discovered that birds do the same thing in the early morning, just as the sun is shining.
By studying the trill rate… read more about Why Birds Sing Loudly in the Morning »
DURHAM, N.C. -- With mosquito season upon us, people are stocking up on repellents to prevent itchy bites. Bug repellents are important because they don’t just protect against the buzzing, blood-sucking little pests -- they also safeguard against the diseases they carry, which kill some 700,000 people worldwide each year.
Surprisingly, despite widespread use, no one understood exactly how most mosquito repellents keep the insects away. Now researchers are starting to uncover the first pieces of the puzzle.
A new study has… read more about How One of the Oldest Natural Insecticides Keeps Mosquitoes Away »
DURHAM, N.C. – Mantis shrimp don’t need baby food. They start their life as ferocious predators who know how to throw a lethal punch.
A new study appearing April 29 in the Journal of Experimental Biology shows that larvae of the Philippine mantis shrimp (Gonodactylaceus falcatus) already display the ultra-fast movements for which these animals are known, even when they are smaller than a short grain of rice.
Their ultra-fast punching appendages measure less than 1 mm, and develop right when the larva exhausts its yolk… read more about Baby Mantis Shrimp Don’t Pull Their Punches »

DURHAM, N.C. -- Female baboons may not have bills to pay or deadlines to meet, but their lives are extremely challenging. They face food and water scarcity and must be constantly attuned to predators, illnesses and parasites, all while raising infants and maintaining their social status.
A new study appearing April 21 in Science Advances shows that female baboons with high life-long levels of glucocorticoids, the hormones involved in the ‘fight or flight’ response, have a greater risk of dying than those with lower levels… read more about Stress and Death in Female Baboons -- as Measured by Hormones in Poop »
DURHAM, N.C. -- When marine biologist Eleanor Caves of the University of Exeter thinks back to her first scuba dives, one of the first things she recalls noticing is that colors seem off underwater. The vivid reds, oranges, purples and yellows she was used to seeing in the sunlit waters near the surface look increasingly dim and drab with depth, and before long the whole ocean loses most of its rainbow leaving nothing but shades of blue.
“The thing that always got me about diving was what happens to people's faces and lips… read more about Warming Seas Might Also Look Less Colorful to Some Fish. Here’s Why it Matters. »
DURHAM, N.C. -- Some guys have it all: the muscle, the power, the high social status, the accelerated aging.
But wait. Faster aging? Who wants that? For male baboons, it’s the price they pay to be at the top.
New research appearing April 6 in eLife by Jenny Tung, associate professor of evolutionary anthropology and biology at Duke University, and her colleagues shows that male baboons that climb the social ladder age faster than males with lower social standing. If a male drops in social status, his estimated rate of… read more about A Male Baboon’s Dominance Gives Him Babies, but Costs Him Years »
DURHAM, N.C. -- Emily Ury remembers the first time she saw them. She was heading east from Columbia, North Carolina, on the flat, low-lying stretch of U.S. Highway 64 toward the Outer Banks. Sticking out of the marsh on one side of the road were not one but hundreds dead trees and stumps, the relic of a once-healthy forest that had been overrun by the inland creep of seawater.
“I was like, ‘Whoa.’ No leaves; no branches. The trees were literally just trunks. As far as the eye could see,” said Ury, who recently earned a… read more about Mapping North Carolina’s Ghost Forests From 430 Miles Up »
You can blame the Boy Scouts for Dr. William Morris’ career. That wouldn’t be such an unusual origin story for an ecologist. What is unusual are the lengths to which Morris takes his passion for the great outdoors. Studying nature wasn’t enough: he wanted to study nature in extreme environments.
Morris’ research focuses on understanding how plants and the insects that eat and pollinate them respond to climate change. His work takes him to some of the most severe environments on Earth, including the 10,000-foot peaks of… read more about Professor Bill Morris Named a Fellow of the Ecological Society of America »

DURHAM, N.C. -- If you binged on high-calorie snacks and then spent the winter crashed on the couch in a months-long food coma, you’d likely wake up worse for wear. Unless you happen to be a fat-tailed dwarf lemur.
This squirrel-sized primate lives in the forests of Madagascar, where it spends up to seven months each year mostly motionless and chilling, using the minimum energy necessary to withstand the winter. While zonked, it lives off of fat stored in its tail.
Animals that hibernate in the wild rarely do so in zoos… read more about An Unusual Creature Is Coming Out of Winter’s Slumber, and Here’s Why Scientists Are Excited »
Dr. Paul Manos was interviewed by the North Carolina journal The News and Observer, to talk about the future of oak trees in light of climate change. The research Triangle area, composed of Durham, Raleigh, and Chapel Hill, is home to several species of oak, such as red oak, water oaks, darlington oaks, and overcup oak. Raleigh itself is known as The City of Oaks. Dr. Manos studies the evolution of morphological characteristics and the phylogenetic relationships of several species of hard wood families, including oaks.… read more about Prof. Paul Manos Interviewed by The News and Observer »
Duke pilot testing effectiveness of campus wastewater sampling to detect SARS-CoV-2, and comparing it to nasal swabs
Using established methods for screening human sewage for the presence of SARS-CoV-2, the virus that causes COVID-19, Duke University is piloting a study to compare what can be learned from sewage with what can be learned from a rigorous nasal swab testing program.
The university has been testing wastewater from three residence halls for the virus and comparing that data to what is being learned from swab… read more about Comparing the Swab to the Sewer »
DURHAM, N.C. – As a next step in Duke University’s exhaustive, campus-wide testing program during the COVID pandemic, the university is employing a genome sequencing core facility in downtown Durham to identify the specific strains of the SARS-CoV-2 virus that have been found on the campus and in the Duke Health system.
So far, the gene sequencing effort has turned up two ‘variant’ forms of the virus, the California variant (B.1.427/B.1.429), which showed up in campus and health system samples after the holiday break, and… read more about Duke Starts Sequencing COVID Genes, Finds Two Known Variants »
