EVERYONE LOSES TIME to COVID-19. Martin Fischer lost most of a month to masks.

“I’m not getting anything done other than this,” says Fischer, associate research professor in the department of chemistry. “The last three weeks have been this, 100 percent.” By “this” he meant media availabilities, Zoom interviews, and various other responses to his attempt to help out as masks spread through the culture.

It was the end of sophomore year in college, and I was looking for an interesting way to spend the summer and earn a little money. I stumbled across an ad for a summer job at the Ontario Science Center in Toronto that sounded fascinating—reconstructing the skeleton of a sixty-foot fin whale that had stranded the previous summer in Nova Scotia. I knew nothing about whales, but the concept of marine biology sounded pretty good to a kid who grew up in the middle of Canada.

BILL KAELIN LIKES A PUZZLE.

Not a crossword, not a Sudoku. You won’t find Kaelin playing Words With Friends, and Board Game Night was never a staple in the Kaelin household. A puzzle demands concentration. It demands focus; it requires you to pay attention to one thing at a time.

This issue’s long-planned cover story follows one researcher’s fixation on developing an AIDS vaccine. We could not have planned for what’s become a fresh global fixation, on the coronavirus first identified in Wuhan, China. By late January, it had disrupted university-supported travel to China and had rejiggered the academic calendar at Duke Kunshan University.

A graphic of number as if in computer code

My boys have dark brown curls and mischievous smiles. They speak with clarity and confidence. They move with boundless energy but also with unexpected grace. They enjoy playing with their lovies, reading with their daddy, and dancing with me, their mommy. They were born in St. Louis, but their great-grandparents were born in Africa, Asia, and Europe. They are six and eight. They represent the best of America. And I am scared for their future.

Billy Pizer, professor of public policy, economics, and environment, and his colleague Tim Profeta, director of the Nicholas Institute for Environmental Policy Solutions, wanted to find a hands-on way to engage students with the issue of emissions regulation. The Bass Connections energy-theme courses, in which graduate students and undergrads work together in small interdisciplinary groups, seemed the ideal setting in which to launch a new research project on the topic.

When David Shiffman ’07 applied to Duke in 2002, he wrote his application essay about the first time he swam with sharks. The then-landlocked Shiffman, who grew up in Pittsburgh, included an anecdote about consoling his father before his dive into the deep with an eleven-foot tiger shark—“Don’t worry, Dad; they don’t usually eat people.”

December 26 marks the tenth anniversary of one of the worst natural disasters of all time—the Indian Ocean tsunami, which devastated Indonesia’s Aceh province, killing some 160,000 people. Since 2005, Elizabeth Frankenberg, a professor of public policy, has led an Indonesia-based fieldwork project that has followed a group of 32,000 people (first interviewed, pre-tsunami, in 2004).

From the outside, W. Steven Burke’s elegantly understated Greek Revival home and adjoining buildings—all designed by him—in the heart of the historic district in Hillsborough, North Carolina, offer no hint at the worlds and wonders inside. But cross the threshold and suddenly you’re surrounded by hundreds and hundreds of small buildings that occupy nearly every surface.

It’s a mid-April morning in Highland Park, a neighborhood just north of Richmond, Virginia, where historic Queen Anne-style homes the color of popsicles give way to boarded-up buildings along a slight Main Street.

When I was diagnosed with breast cancer, at the age of thirty-five, I did not see my life pass before my eyes. I did not have black spots at the edge of my vision. Instead, I thought, “Oh, crap, what do I do now?”

Don Byrne enters the garden through one of four gates.

ON A MORNING in early 2006, Don Byrne walked through an overgrown field of grass. Alongside trudged his father, who, despite the early hour, carried a bottle of Jameson Irish whiskey. At the highest point on the land, the two men paused. It was here that they wanted to drill the well. In a makeshift christening, they sprinkled the land with liquor.

Having HIV testing close to one’s home makes in more likely that one will get tested. At the same time, HIV preferences vary greatly across individuals, according to new research conducted by Duke Global Health Institute faculty members. The findings could help inform how HIV-testing services are adapted and expanded across sub-Saharan Africa.

The old saying goes, “Yawns are contagious,” but have you considered the biology behind it? While previous studies have suggested a connection between contagious yawning and empathy, new research from the Duke Center for Human Genome Variation finds that contagious yawning may decrease with age and is not strongly related to variables like empathy, tiredness, and energy levels.

The study of the human body was intimately connected with art during the Renaissance era. From this visual culture emerged fugitive sheets, three-dimensional illustrations of human internal organs. Although widely disseminated from the 1530s until the late seventeenth century, fugitive sheets were typically printed as a single broad sheet rather than as part of a bound volume, explaining why so few exist today (hence the “fugitive” designation).

In the spring of 1961, Ida Stephens Owens graduated summa cum laude from North Carolina College—now North Carolina Central University— with a major in biology. Just a few months earlier, Duke University’s board of trustees voted to integrate its graduate and professional schools. Owens came to the attention of Daniel C. Tosteson, then chair of the physiology department, who was recruiting accomplished students from black colleges to pursue advanced degrees in the sciences.

“The rolling sand dunes and gentle waves of Emerald Isle are so picturesque that I almost forget why I am here: to conduct a necropsy on a stranded bottlenose dolphin,” wrote Samantha Emmert from the Duke Marine Lab in early 2014. Emmert spent her junior year researching an outbreak of morbillivirus epizootic, a measles-like virus that has ravaged dolphin populations along the Atlantic Coast since last summer.

Athletes who suffer from torn-cartilage injuries may soon be in luck. Mimicking the strength and suppleness of natural cartilage is tricky, but Duke researchers have developed a synthetic version that comes pretty close to the real thing.

Articular cartilage, the tissue between bones and joints, enables us to bend body parts like elbows, hips, and knees. But overuse or injury can lead to wear-and-tear on cartilage, making movement painful and difficult.

By the time you finish reading this story you will have learned the following things: Men can hear fertility status in a woman’s voice—and they like it; a big, deep “me Tarzan” voice seems to help not just men but women succeed in politics and business; the pitch and tone of a CEO’s voice in a conference call may give you information about stock performance; women have it even tougher than you knew; and there may be evolutionary value in this whole “vocal fry” trend (think Kardashian end-of-s

Fossils

November 19, 2013

There’s an eerie elegance to the old bones of the Palaeopropithecus sloth lemur. Perhaps 8,000 years ago, the (then-living) lemur hung upside down in Madagascar. Nowadays, its skeleton rests like a hidden treasure at Duke’s Division of Fossil Primates on Broad Street, among more than 25,000 other fossils of the earliest primates and animals.

Cloud-draped Marojejy National Park rises like a deep green island on a pastel sea of human disturbance. In each muddy quadrangle of rice paddy around the island’s feet, a single cow is staked out to graze and defecate. This rainforest preserve is a dwindling refuge of Madagascar’s native biodiversity, 80 percent of which exists nowhere else on Earth.

Women sunbathing on a beach

We’re all too familiar with the symptoms of prolonged exposure to UV rays. There’s the crimson skin, the itchiness, and of course, that overpowering feeling of lethargy. But what actually makes the skin hurt to the touch? A Duke researcher believes he has an answer for sunburned beachgoers: TRPV4.

Even Blake S. Wilson B.S.E.E. ’74 is in awe of the cochlear implant, and the electrical engineer is one of the core developers of the device. “Most of today’s implanted patients can understand everyday speech with hearing alone, without lip reading—many in noisy environments, some even on the telephone.

1. It really is a popularity contest: Rhesus macaques that have large, strong social networks tend to belong to families of similarly amiable macaques. Not only that, but playing nice with others tends to yield greater reproductive success. A corollary shows that the most aggressive monkeys have greater reproductive success—but so do the most passive monkeys. The loser? The monkey in the middle.

Birds do it. People do it. Now, Duke researchers are convinced that mice, too, can learn how to imitate songs to woo a mate. The surprising conclusion comes from a team of Duke neurobiologists who observed that male mice imitate the ultrasonic squeakings of other males. The researchers identified certain features in a mouse’s brain that are similar to the parts of the brain humans and birds use to learn vocalization, which suggests mice can pick up a tune.
