Doing chemistry with the sun

"I derive great joy from teaching young scholars how to tickle out Mother Nature's secrets and how to invent," says Emory chemist Craig Hill, winner of the 2009 Herty Medal. During the Sept. 17-18 celebration of the prize, given to an outstanding chemist by the Georgia Section of the American Chemical Society, Hill will give a series of talks to young scientists.

The theme will be green energy, including a description of Hill's recent work on developing the first prototypes of stable, molecular water oxidation catalysts – a critical component to make solar energy cheap and efficient enough to go mainstream.

“People love the idea of doing chemistry with the sun to create a source of energy that is sustainable and not damaging to the planet,” Hill says. “It’s an idea at the nexus of need, scientific invention and creativity.”

Forget sharks: It's Dinosaur Week!

Did you know that dinosaurs lived under water in Georgia? Have you ever heard of an Appalachiosaur?

In addition to such local oddities, Georgia Public Broadcasting's Dinosaur Week features NOVA and BBC programming of the greatest dinosaur finds of all time. Watch for a live interview of Emory paleontologist Anthony Martin between programs this evening.

Martin is a trace fossil specialist, known for the first discoveries of dinosaur burrows.

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."
