The Effects of Alcohol on Brain Development

Speaker: Scott Swartzwelder, Duke Institute for Brain Sciences

See previous Periodic Tables

Allen Wilcox, Uncovering the Mysteries of Human Fertility: On Sex, Fertile Days, and Why the Rabbit Dies, July 2009:

"The audience quickly got caught up in the topic, and they asked great questions. You’ve created a forum that truly bridges the gap between scientific research and the general public that makes research possible.  (And besides, how many times do I get to say to a packed house, “Oh, and by the way, the person holding my right ovary is my mom”!)"

Mohamed Noor, On the Origin of Species, Really, May 2009:

"I thoroughly enjoyed talking with folks at Periodic Tables- the house was packed, the audience was engaged, the food was great- an all around  great experience!  I was especially impressed at the incredible range of attendees, both in age (from school-kids on up) and in specialty/occupation.  And they all asked great questions, too.  What a great experience- thank you so much for having me."

Phillip Barron, Human Enhancement, December 2008:

"I just wanted to let you know how much I enjoyed last night's event. The audience was very engaging, and I was challenged by some of their questions. I will make it known in any future publication that I had such a great dialogue on these complicated issues with folks from the Periodic Tables event."

Steve Cummer, The Invisibility Cloak, October 2008:

"The experience was every bit as interesting as I'd hoped. Attendance was good and I got a lot of thoughtful, relevant questions from the audience. It's a great opportunity to connect with the public, and I'm glad I did it."

 

Periodic Tables is a monthly gathering where curious adults can meet in a casual setting to discuss the latest science in plain English. At Periodic Tables, you will chat with your neighbors and local experts about interesting and relevant science happenings right here in the Triangle and beyond. No lengthy PowerPoint presentations, no drawn-out seminars, no confusing jargon. Simply smart and relevant science in a relaxed atmosphere. Eating and drinking is encouraged, and there is no such thing as a stupid question.

Come out and join us on the second Tuesday of every month for a lively conversation at Broad Street Café. Come early to enjoy the fantastic appetizers, wood-fired pizza, burgers and salads that complement their 15 beers on tap and full liquor bar.

Periodic Tables is based on the popular Science Café format. As explained by our good friends at WGBH in Boston, a science café's casual meeting place, plain language, and inclusive conversation create a welcoming and comfortable atmosphere for people with no science background.

Each event is organized around an interesting topic of conversation. A scientist gives a brief presentation and sometimes shows a short video clip to kick off the discussion. You can leave a café meeting when you want, but you'll miss out if you show up late.

There are many variations on the basic science café. One café might have a trivia quiz. One might include a panel of scientists. And yet another may include a storyteller. Topics range across all sciences, and some cafés even explore connections between science and other disciplines, like the arts.

Ocean Oil Spills: They have happened before - and we haven't learned much

Speaker: Fred Pfaender, Professor of Environmental Microbiology, University of North Carolina School of Public Health

Oil spills have been around for a long time. Dr. Pfaender discussed what the spill means for the Gulf and how it might be cleaned up with his ideas. Dr. Pfaender also discussed why we can't seem to be able to learn from past experiences.

Dr. Pfaender is a petroleum microbiologist who has been involved in many oil spills starting with the Amoco Cadiz grounding in Normandy in the 70's to Ixtoc on the Gulf of Mexico. He was also one of EPA's advisors for the clean up of the Exxon Valdez in Alaska. His special expertise is how microorganisms break down contaminants, including oil.

The Importance of Being Dad: Paternal Care in Primates

Speaker: Dr. Susan Alberts, Associate Professor in the Department of Biology at Duke University 

Although human males often get criticized for being "deadbeat dads", the truth is that compared to most mammals, human males are simply outstanding fathers. Join us as Dr. Susan Alberts discusses why we don't generally expect male mammals to provide paternal care (answer: because we think they usually can't recognize their own offspring), and the unusual and surprising case of paternal care in a primate species where we least expect to find it.

In the baboons of the Amboseli basin of southern Kenya males differentiate their own offspring from other males' offspring, and provide care to them. Dr. Alberts will talk about why this should be so, and what it means about males of all species and their tendencies to provide offspring care.

Why Dogs Love Us

Speaker: Dr. Brian Hare, Assistant Professor in Evolutionary Anthropology at Duke University 

More has been discovered about dog intelligence in the last decade than the preceding 100 years. The Duke Canine Cognition Center was founded to continue studying how dogs understand their world, how dogs might have evolved, and how we might help dogs be even more successful at helping people. Dr. Brian Hare shared some of his work comparing dogs to various species like wolves and chimpanzees.

Speaker: Dr. Emily Bernhardt, Assistant Professor of Biology at Duke University and Program Leader at the Center for Environmental Implication of NanoTechnology

Nanotechnology has the enormous potential to change our society. New advances in medicine, energy production, environmental cleanup and better access to clean water are just a few of the many possibilities. According to the Project on Emerging Nanotechnologies, the number of products that use nanomaterials has increased almost 380% since 2006. But, is it the same special properties that make nanoscale materials so useful that also pose potential risks to humans and the environment? Dr. Emily Bernhardt from the Center for the Environmental Implications of NanoTechnology discussed with us the fate of nanomaterials in our environment and why you should care.

Hide and Seek in the Open Sea: Vision and Camouflage in Marine Animals

Speaker: Dr. Sönke Johnsen, Associate Professor of Biology, Duke University

The open ocean, which comprises over 99.5% of the earth’s liveable space, is an exceptionally difficult place to hide. The background is featureless, predation is intense, and there is nothing to cower behind. Complete invisibility is usually the only successful strategy. Dr. Sönke Johnsen shared a colorful presentation on how animals in the open ocean have evolved a number of beautiful tricks that are absent or rare in other environments.

On the Origin of Species, Really

Speaker: Mohamed Noor, Duke University

Hear Duke evolutionary biologist Mohamed Noor discuss the work that made him one of only a dozen scientists honored with the Darwin-Wallace Medal last year. This prize is given only once every fifty years to those twelve scientists who have done the most to advance Darwin's thinking.

Although Darwin's book title suggested that he provided us with insights on the origin of species, in fact, he only focused on the process of divergence within species and assumed the same process "eventually" led to something that could be called a new species.

Rekindling Wood Energy in America

Speaker: Dan Richter, Duke University

Most people agree that we need to switch from fossil fuels to renewable energy, but few agree on the best method. The rate and sustainability of this transition will be determined in the next few years. In Europe, the renewable energy “heavyweight” is widely recognized to be advanced wood combustion (AWC); in America, wood is not even mentioned in most discussions about renewables. Two decades of European experience with AWC demonstrate that wood is “shovel ready” to contribute to the renewable energy portfolio of the United States.

The Invisibility Cloak

Speaker: Dr. Steven Cummer

“We’ve devised a recipe for an acoustic material that would essentially open up a hole in space and make something inside that hole disappear from sound waves,” says Steven Cummer, a scientist at Duke’s Pratt School of Engineering. Such a cloak might hide submarines in the ocean from detection by sonar or improve the acoustics of a concert hall by effectively flattening a structural beam.
