Thoughts From An Optimist

Writer: 

For a guy who spends his time studying climate change, facing down the future of an Earth warming at an astonishing rate, under the management of a population that commonly resists even admitting its problems, Drew Shindell seems surprisingly optimistic.

Shindell, Nicholas Professor of earth science, has drawn recent attention as a coordinating lead author for the Intergovernmental Panel on Climate Change “Special Report on Global Warming of 1.5°C,” released this past fall. The report addressed the terrifying climate challenge humanity faces as it moves into an uncertain future.

New Energy Fuels Bass Connections

Writer: 

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.

Everything About Every Lemur

Writer: 

Nearly 4,200 members of the more than forty species of prosimians—lemurs, lorises, bush babies, and tarsiers—have lived at the Duke Lemur Center since 1966, and the center has been recording data on them. Much of that information was in handwritten logbooks until 2012, when DLC primatologist Sarah Zehr worked with software developers to create a historical record and a living database that includes information like body mass at multiple ages, ancestry, reproduction, longevity, and mortality, as well as a bank of blood, DNA, urine, skin, and organ-tissue samples.

A Dictionary For Your Ears

Writer: 

The foothills are alive...with the sounds of creaky wooden porches, husky train whistles, and tobacco plants being scythed. These sounds are stored in the Sonic Dictionary, a digital archive of acoustics hosted by the Audiovisualities lab at Duke’s Franklin Humanities Institute. It’s a kind of “Wikipedia of sound,” according to English doctoral student Mary Caton Lingold, who conceived the project.

More to Give

Writer: 

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?”

Bookbag: Veterans Oral History Project

Writer: 

THE CATALYST: In 2000, Congress passed legislation to create the Veterans History Project. Housed in the Library of Congress, the ongoing collection includes correspondence, audio narratives, and visual materials from veterans of every American war since World War I. Several years ago, Center for Documentary Studies instructor Michelle Lanier and then-visiting professor Elaine Lawless saw an opportunity to contribute to the project at duke.

On the Plaza: Coastal Concerns

Writer: 

“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.

Faux cartilage could take joint pain away

Writer: 

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.
