News from the future

Emory is among a group of leading research universities behind Futurity, a new online research channel covering the latest discoveries in science, engineering, the environment and health. The idea is to share important breakthroughs in a way that stirs the imagination, raises questions, and makes readers want to learn more.

Emory discoveries featured on Futurity recently include everything from a new patch method for flu vaccines to programming bacteria to clean up pesticides.

Read more about Futurity in Scientific American, the Atlanta Business Chronicle and the San Jose Mercury News.

Get a masters in bioethics

Graphic from Emory Center for Ethics

Emory's Center for Ethics has launched a masters degree program in bioethics that provides advanced, interdisciplinary study of the social and ethical challenges facing the life sciences. "The program is so innovative and exciting, I wish I could take it myself," says Paul Root Wolpe, director of the center. Faculty in the program come from medicine, nursing, public health, law, theology, business, the life sciences, philosophy, religion, sociology and psychology.

The biology of shared laughter and emotion

"It's almost impossible not to laugh when everybody else is," writes psychologist Frans de Waal, in his new book "The Age of Empathy: Nature's Lessons for a Kinder Society."

Natural History Magazine offers an excerpt of the book:

"The infectiousness of laughter even works across species. Below my office window at the Yerkes Primate Center, I often hear my chimps laugh during rough-and-tumble games, and cannot suppress a chuckle myself. It’s such a happy sound. Tickling and wrestling are the typical laugh triggers for apes, and probably the original ones for humans. The fact that tickling oneself is notoriously ineffective attests to its social significance. And when young apes put on their “play face” (as the laugh expression is known), their friends join in with the same expression as rapidly and easily as humans do with laughter.

"Shared laughter is just one example of our primate sensitivity to others. We aren’t Robinson Crusoes, sitting on separate islands; we’re all interconnected, both bodily and emotionally. This may be an odd thing to say in the West, with its tradition of individualism and liberty, but members of the species Homo sapiens are easily swayed in one emotional direction or another by their fellows.
"That is where empathy and sympathy start—with the synchronization of bodies—not in the higher regions of imagination, or in the ability to consciously reconstruct how we would feel if we were in someone else’s 'shoes.' And yet empathy is often presented as a voluntary process, requiring role taking, higher cognition, and even language. Accordingly, most scholarly literature on empathy is completely human centered, never mentioning other animals. As if a capacity so visceral and pervasive could be anything other than biological! To counter such widespread views, I decided to investigate how chimpanzees relate to and learn from one another."

Chimps mirror emotion in cartoons

Animation by Devyn Carter, lead research specialist, using LightWave 3D, NewTek, Inc.

Emory researchers have documented the first example of chimpanzees empathizing with computer animation. The study, published in the Proceedings of the Royal Society B, is part of an effort to learn more about the impact of cartoons and video games on the human brain.

“Humans experience emotional engagement with animated characters, empathizing with happiness, sadness or other emotions displayed by the characters,” said Matthew Campbell, a post-doctoral fellow in psychobiology, and the lead researcher. “Previous studies have suggested this type of emotional engagement may be to blame when children mimic violent video games and cartoons, so we thought it important to learn more.”

Yawns were chosen for the chimpanzee study, since they are large, unmistakable expressions, and they are contagious – the way that smiles, frowns and fear are contagious.



The chimps yawned significantly more in response to 3D animations of yawning than they did to animated chimps making control mouth movements.

“Next, we want to study what aspects of animation make it more or less likely to be mimicked,” Campbell said. “One of the first things we’re going to look at is whether realism is important for the chimpanzees to empathize with what they’re seeing."

The knowledge gained could help in the design of animation to promote imitation, such as therapies for children with autism, or to limit imitation, such as violent video games.

Campbell’s advisor is psychologist Frans de Waal, director of the Living Links Center at Yerkes National Primate Research Center.

Child soldiers of Nepal inspire film

Brandon Kohrt received his PhD from Emory anthropology in 2009, and writes in the department newsletter:

"After a few months of fieldwork in Nepal, I learned that there were large numbers of child soldiers being sent home from the Maoist Army after the conclusion of the People’s War in 2006. I had not even known that child soldiers existed in Nepal. I had thought of child conscription as predominantly a human rights violation in African conflicts. However, the mental health and psychosocial care of former child soldiers quickly became central to my research and intervention work."

Kohrt teamed with an Atlanta filmmaker to tell the children's stories in "Returned: Child Soldiers of Nepal's Maoist Army." The award-winning documentary will be shown on campus on Thursday, Sept. 24. Kohrt also graduated from Emory's School of Medicine in 2009, and is now completing his residency in the department of psychiatry.
