What’s it like to play a grand piano beneath a Saturn V rocket?

“It’s pretty incredible,” says Gary Motley, Emory director of jazz studies, and one of the few people who can answer that question. Motley traveled to the Kennedy Space Center in Florida earlier this week, to perform at a send-off party for his cousin, astronaut Bobby Satcher, who is on the crew of the Atlantis space shuttle.

Satcher’s relatives flew in from around the country for the party arranged by his wife, D’Juanna. Motley (below right) played “How High the Moon,” and other jazz tunes for the event, which was held in a hangar of the space center. “They’ve got a Saturn V rocket mounted horizontally from the ceiling,” Motley says. “It’s unbelievably big. Just guessing, I’d say it’s the length of a 12-story building.”

Satcher was unable to attend the send-off in person, since he was undergoing flight preparation, but he spoke to the guests via phone. "He asked who was there, and 300 people cheered back," Motley says. "I think he was surprised by the magnitude."

It’s the first space flight for Satcher, who will be doing a space walk. For a relaxing diversion during the mission, the astronaut took along Motley’s latest jazz CD, a collection of original music entitled “Renaissance.”

“I’m thrilled!” Motley says. “I think it’s also special to him, because he’s taking that connection to the family with him into space.”

The highlight of the experience for Motley was the launch itself, on Monday at 2:29 p.m. “The sound! I’ve never heard anything like it,” he says. “When the smoke cleared on the launch pad and the Atlantis lifted off, it was so bright, it was like looking at the sun. It moved incredibly fast. They announced it was going 200 miles per hour, then 2,000 miles per hour, then 9,000. When somebody that you know and are connected to is on board, it’s overwhelming.”

Nazi medicine: A needle in history's side

The course “Nazi Politics and Medicine” is not for the faint of heart. “It isn’t easy to study atrocities,” says Astrid M. Eckert, assistant professor of history. “We’re looking at some really gruesome subject matter, and we all struggle in dealing with it.”

The U.S. Holocaust Memorial Museum sponsors the course, which is offered through the Emory College history department, the Institute of Liberal Arts and the schools of medicine, nursing and public health. (USHMM collection graphics, above and below, are from a 1941 public health brochure, counseling couples to select marriage partners based on genetics.)

"The subject matter raises difficult questions, many of which we are still grappling with in a much different historical context," says Sander Gilman, professor of liberal arts and sciences, who co-teaches the course with Eckert.

Jacqueline Black, a senior majoring in American Studies, was shocked to learn during the class that several U.S. states had sterilization laws for criminals and the “feeble minded” before the Nazis. “Some of the exact wording of the Nazi law was taken from U.S. laws,” says Black, who is researching a paper on the topic. “That was a real wake-up call for me.”

"I was surprised that German physicians joined the Nazi party earlier and in greater numbers than many other demographics," says Luke Reimer, a sophomore majoring in biology and history who plans to go to medical school. “The medical field in Germany underwent a severe crisis and some physicians were living on the streets, selling sausages. For me, it’s an interesting story. Physicians should look at their responsibilities as a caregiver first and put their careers second. I think German physicians inverted this relationship during this phase of history.”


The course also delves into important science done in the totalitarian state. "All of the early work on the relation between cancer and smoking was done in Germany under the Nazis,"  Gilman says.

Would it be ethical for a modern geneticist to consider data gathered by the infamous Josef Mengele and his twin experiments? "These questions get really, really complicated," Gilman says.

Students read and watch videos of first-hand accounts by both perpetrators of atrocities, and survivors of pogroms against Jews, homosexuals and the disabled. The testimony of real people describing what happened to them is often more gut wrenching than photos of mutilated corpses, Eckert says.

“After we watched a clip of an elderly homosexual man recalling what he went through at Dachau, there was silence in the class,” she says. “That was a real game changer. I felt a rush of empathy come out of the students.”

Her math adds up to a brilliant career

Emory math professor R. Parimala has received one of the highest honors in her field: Selection as a plenary speaker for the International Congress of Mathematicians, set for Aug. 19–27, 2010, in Hyderabad, India. The ICM is held only every four years, and is the most important activity of the International Mathematical Union. The 20 plenary speakers are chosen from top talent throughout the world.

It may be a lofty honor, but Parimala remains decidedly down to earth. “I’ve always been very comfortable with math,” she says, relaxing in her office after teaching a class. Her hair hangs down her back in a long dark braid and she looks casually elegant in a cotton tunic, shawl and pants.

The outfit is called a “salwar-kameez,” she explains, and is from northern India. She grew up in the southern tip of the country, in the state of Tamil Nadu, where the saree is the traditional dress. “I love to wear a saree, but it’s six yards of fabric and hard to maintain,” she says. “Ironing is a bit boring.”

When she graduated from high school, her father sat her down and asked her what she wanted to do. “I said, ‘I want to continue with math. Period,’” Parimala recalls, adding that it was an unusual path for a female. “My father knew I had an aptitude for math and was very supportive of my higher studies.”

At Stella Maris College in Chennai, India, she says that she briefly considered focusing her studies on Sanskrit poetry, but math won out. “Math has the beauty of poetry. Its abstractions are combined with perfect rigor.”

For her doctorate, Parimala attended the Tata Institute of Fundamental Research in Mumbai, one of the top institutes in India for the basic sciences. She spent most of her career on the faculty there, until she joined Emory in 2005.

“I’ve always enjoyed teaching,” Parimala says, “and it’s fun to work with undergraduate students. They are so enthusiastic.”

She also looks forward to new research challenges, primarily in algebraic groups, and quadratic forms. “There are many interesting questions that keep my attention,” she says. “Math is dynamic, not only internally dynamic, but across disciplines.”

Parimala was recently invited to speak at Nehru University in Delhi, during a conference aimed at inspiring more female students to focus on math.

“Most bright students in India choose another career over basic sciences,” Parimala says. “It’s a global phenomenon, actually, because they think there are more attractive jobs in other areas. But math offers a challenging and rewarding profession. If you have a love and a talent for it, you should come to math. That is my plea.”

Daily pot smoking may hasten psychosis onset

Progression to daily marijuana use in adolescence may hasten the onset of symptoms leading up to psychosis, an Emory study finds. The study was published in the November issue of the American Journal of Psychiatry.

The researchers analyzed data from 109 hospitalized patients who were experiencing their first psychotic episode. The results showed that patients who had a history of using marijuana, or cannabis, and increased to daily pot smoking experienced both psychotic and pre-psychotic symptoms at earlier ages.

"We were surprised that it wasn't just whether or not they used cannabis in adolescence that predicted the age of onset, rather it was how quickly they progressed to becoming a daily cannabis user that was the stronger predictor," says Michael Compton, lead author and assistant professor of psychiatry in the Emory School of Medicine.

The Emory study focused on what is known as the prodromal period, when a person has symptoms such as unusual sensory experiences, which are often precursors to frank hallucinations and delusions. “The prodromal period is especially important because it’s considered to be a critical time for preventive intervention,” says Elaine Walker, a co-investigator of the study and professor of psychology and neuroscience at Emory.

Getting a grip on cultural evolution

How did humans go from the ability to make a stone axe to a computer mouse? Science writer Matt Ridley posed that question during his keynote for the conference on the Evolution of Brain, Mind and Culture.

Both objects are designed to fit into the human hand. “But the hand axe was made to a design that continued to be used for about one million years,” Ridley said. “There’s no continual innovation or progress.”

And while a hand axe was knapped by a single person, a computer mouse requires the efforts of many. “It’s not just the people in the computer mouse company that made it, it’s the people who drilled the oil well from which the oil came for making the plastic. The point is that human intelligence went from being individual to being collective. And that, I think, is the crucial thing that we have to try and understand about the human breakout from being just another species to being this extraordinarily ecologically dominant species.”

So why, when and where did human intelligence become collective?

Ridley argued that, just as sex and the exchange of genes is crucial to speeding up biological evolution, trade and the exchange of goods was the major driver of cultural evolution and the accumulation of innovations.

“The actual swapping of one object for another is unknown outside our species,” Ridley said.

Ridley is the author of “Nature via Nurture,” among many other science books, and the forthcoming “The Rational Optimist.”
