DEER, HUNTING, AND COUGAR-PREY-HUMAN INTERACTIONS
Robert Wielgus, Ph.D., associate professor and the Director of the Large Carnivore Conservation Laboratory in the Department of Natural Resource Sciences at Washington State University, Pullman.
Large carnivores have huge impacts on agriculture, forestry, recreation, and other human activities in the Pacific Northwest -- and they often come into conflict with human's use of land. As white-tail deer have expanded into previously unoccupied areas in Washington State, because of habitat changes (increased hay crops, water sources, numerous, small forest openings) so have cougars -- resulting in increased predation on native fauna and, perhaps, increased human-cougar conflicts. Removing cougars in localized areas appears relatively ineffective because new cougars move in from as far as 100 miles away. We'll hear about the latest studies of deer and cougar populations, and learn what might be done to manage populations and troubling human-cougar interactions.
10 a.m. to 11 a.m.
Patricia K. Kuhl, Ph.D., Co-director, Institute for Learning and Brain Sciences, and Professor, Department of Speech and Hearing Sciences, University of Washington, Seattle.
Infants are born citizens of the world with regard to language. They can distinguish among languages from around the globe. But by the first year of life, they specialize in one, and their ability to discern sounds from other languages declines. Kuhl's research is showing that infants use computation to crack speech codes, and that their social skills play an important role in language learning. So does "parentese," the exaggerated, high pitched language we use to speak to infants baby talk. Such chatter is used by parents in every language studied, from Mandarin to Zulu. Kuhl is trying to untangle how infants learn all of this, and how environment contributes to language learning. She's also looking at infants who are, in one way or another, deficient in language. When she looks at behavior that represents the precursors of language, she sees large differences in children with autism, compared to others. She will explain how the analysis of a baby's babbling might even lead to early diagnosis of autism.
11 a.m. to 11:15 a.m.
11:15 a.m. to 12:30 p.m.
Patricia Hunt, Ph.D., Meyer Distinguished Professor, School of Molecular Biosciences, Washington State University, Pullman.
Hunt and her colleagues were trying to understand why older women face an increased risk of having a baby with chromosomal abnormalities such as Down syndrome. They were using laboratory mice to test the hypothesis that age- related changes in hormone levels influence the egg. Suddenly, and with no apparent reason, the data for the normal control animals went haywire destroying their experiments. After a thorough investigation, lasting months, they discovered that the use of the wrong detergent to wash the mice's plastic cages had damaged the cages and the mice's water bottles. The damage to the plastic cages was causing the release of a substance called bisphenol A, which is widely used in plastics and resins. After half of century of widespread use of plastics, it's now ubiquitous in our environment. Hunt's group is one of several teams showing that even low levels of exposure to bisphenol A can cause chromosome abnormalities. She's now finding reproductive hazards in a wide range of everyday products, and trying to determine the extent of the risks to our offspring and what might be done about those risks. Could this be partly responsible for the explosion in use of fertility treatment? Hunt will tell us what we know and what we need to find out.

DIET, EVOLUTION, AND AGING.
Matt Kaeberlein, Ph.D., Assistant Professor, Department of Pathology, University of Washington, Seattle.
Researchers have known for some time now that a calorie-restricted diet can increase longevity in animals, even in the humble yeast. And calorie-restricted animals are less likely to get age-associated diseases. Exactly how this happens, however, hasn't been clear. Is this some product or by-product of evolution? New research aimed at identifying the pathways that regulate longevity is starting to shed some light on this. Researchers have now discovered several genes that play key roles in determining how diet influences aging. This work is providing insights into how dietary restriction can help the body repair and replace damaged proteins. More importantly, these studies suggest a way to develop dietary restriction "mimetics" compounds that could provide the health benefits of dietary restriction, without the sacrifice. Yes, we've heard this promise about diet drugs many times before but Kaeberlein will tell us why these might be the drugs that really work. He and his colleagues are currently trying to determine which of the newly identified genes are most suitable as targets of future therapies, and which diseases of aging such as cancer, diabetes, heart disease, and neurodegenerative diseases could be helped by these therapies.
3:30 p.m. to 3:45 p.m.
3:45 p.m. to 4:45 p.m.
MAYA PYRAMIDS AND MUONS
Roy F. Schwitters, Ph.D., S.W. Richardson Foundation Regental Professor of Physics, University of Texas, Austin.
More than two millennia ago, Teotihuacan, in Belize, was a thriving city, possibly the largest in the world. Much might be learned about the lives of its residents if archeologists could peer inside Teotihuacan's Pyramid of the Sun. The problem is: How can the pyramid be explored without dismantling it or disturbing its ancient stones? A similar problem was solved in the 1960s, when the Nobel-laureate physicist Luis Alvarez used a technique called muon tomography to explore the Second Pyramid of Chephren in Egypt. It was a kind of archeological CT scan. But it was never feasible in Belize, because there was no way to get a muon detector underneath the pyramid. The chance discovery of a small tunnel under the pyramid, however, has now made that possible. Schwitters and his colleagues at the University of Texas have built and are testing a prototype muon detector. In addition to providing a fascinating glimpse inside the Pyramid of the Sun, the technology is potentially useful for studying underground aquifers and other sub-surface structures.
4:45 p.m. to 5:45 p.m.
IVORY, WHALES AND DNA.
Samuel K. Wasser, Ph.D., Director, Center for Conservation Biology, and Research Professor, Department of Biology, University of Washington, Seattle.
The illegal trade in elephant ivory is once again booming. Illegal ivory seizures have tripled in the last couple years, with no concomitant increases in enforcement efforts. The price of high quality ivory has simultaneously quadrupled to $850 per kilogram over the same period. Shadowy organized crime figures in Hong Kong, Japan and China are driving this illegal trade, some of whom also have links with the narcotics and arms trades. Wasser and his colleagues who are collaborating with Interpol to block the ivory trade will tell us how they track elephant DNA to determine locations of poaching hotspots. That, in turn, can help law enforcement officials with their always scarce resources to target the most critical regions, and force countries to accept responsibility for the trade. Wasser has also developed unique methods using dogs to track wildlife health over large remote areas, in species ranging from spotted owls to whales. Tracking whales with dogs: Sound impossible? Wasser has done it.

FRACTALS ON WALL STREET
Benoit Mandelbrot, Ph.D., Battelle Fellow Emeritus, Pacific Northwest National Laboratory, Richland, Wash., and Sterling Professor of Mathematical Sciences, Emeritus, Yale University, New Haven, CT.
Markets, like oceans, are turbulent. They're rough and jittery, with small changes on some days and large changes on others. Mandelbrot, the father of fractal geometry whose work extends from snowflakes to coastlines and the structure of broccoli is interested in shapes that appear similar at different magnifications, patterns that repeat at different scales. Mandelbrot argues that markets are not mysterious; they are complex systems that can be studied. Individuals move on their own paths, but they come together at certain moments to trade. They aren't rational, and they don't think alike. And markets are composed of thousands or millions of their interactions. But that doesn't mean their actions can't be analyzed. Fractal analysis is a mathematical tool for separating these market complexities into pieces that can be described realistically to see how they inter-relate and interact. Mandelbrot's analysis suggests some interesting real-world trading strategies. If you have the stomach, you might want to try them on your own portfolio.
10 a.m. to 11 a.m.
PRIMATES AND DISEASE.
Lisa Jones-Engel, Ph.D., Research Scientist, Division of International Programs, Washington National Primate Research Center, University of Washington, Seattle.
The transmission of disease from non-human primates to humans is an important and often unrecognized threat to public health. Likewise, human diseases pose a significant danger to non-human primates, especially those on the brink of extinction. The problem is rapidly getting worse, aggravated by economic development, globalization, and human population growth. We'll learn how people, primates, and pathogens interact in the rapidly changing global environment and how studying these interactions can prevent disease outbreaks in both people and animals. Most of the examples will come from Asia, with its rich diversity of non-human primates and a long tradition of close contact between people and animals. This contact occurs in a variety of circumstances, ranging from the exotic monkey temples of Bali to the performing-primate schools of Japan. Asia's booming economies and spreading transportation infrastructure are accelerating contact between people and non-human primates, and that is speeding the spread of primate-borne infections, not only in Asia but around the world.
11 a.m. to 11:15 a.m.
11:15 a.m. to 12:15 p.m.
DEEP SEQUESTRATION AND CLIMATE
Pete McGrail, Ph.D., Laboratory Fellow, Pacific Northwest National Laboratory, Richland, Wash.
Carbon sequestration has frequently been proposed as a way to mitigate the planetary rise in atmospheric carbon dioxide. But questions have been raised about its stability, and whether it can make a long-term contribution toward easing climate change. Much of the talk about sequestration has dealt with preserving forests, or ambitious tree-planting campaigns. But McGrail and his colleagues are proposing sequestration of carbon in deep basalt formations, where the carbon can fuse with the rock, locking it in place far below the surface. McGrail will tell us about a variety of ways to grab and sequester carbon, including capturing it with carbon nanotubes. He'll talk about how this might be done, where it can be done, and what impact it could have on global climate change.
12:15 p.m. to 1:45 p.m.
Lunch on your own.
1:45 p.m. to 2:45 p.m.
EMOTIONS, PLAY, ADHD AND DEPRESSION
Jaak Panksepp, Ph.D., Baily Endowed Chair for Animal Well-Being Science at the College of Veterinary Medicine, Washington State University, Pullman.
The basic science of emotion a topic that has proven difficult to study has been transformed by the novel approach of what's called affective neuroscience. That's Panksepp's specialty. He has spent 30 years studying basic emotions, especially the distress caused by social separation, when young animals are left alone. The work on separation was the first step toward a comprehensive science of emotions, a field now paying rich dividends. Panksepp has shown that separation distress in animals is related to sadness in humans, yielding new ideas on how to treat depression. More recently he has shown that "social joy" is common in animals, as in humans, and it can be studied systematically. One notable result of this work was the discovery of laughter (yes, laughter!) in rats. The research has also shown that emotions are closely related to the body's opioid system. Sadness in humans is marked by low opioid levels, while joy is characterized by high opioid activity. He will tell us about the role of play, which, in new genetic studies, has been found to sharply alter gene expression in the brain's frontal lobes in as little as an hour. That, in turn, has led him to a new theory of attention-deficit disorder as a consequence of insufficient play time. He will show how this new understanding of the emotional systems of the brain is leading to new ideas about the genesis and treatment of various psychiatric disorders.
2:45 p.m. to 3 p.m.
3 p.m. to 4 p.m.
A VISIT TO SATURN AND TITAN.
Carolyn Porco, Ph.D., Leader of the Cassini Imaging Team, Director of the Cassini Imaging Central Laboratory for Operations (or CICLOPS) in Boulder, CO, and Adjunct Professor at the University of Colorado in Boulder.
For seven bitterly cold, lonely years, the Cassini spacecraft and its Huygens probe traveled billions of miles on a journey to Saturn and its rings. When it arrived, the flying-saucer-shaped Huygens descended through a hazy atmosphere to land on the alien surface of Titan. The Cassini mission has been and continues to be one of the most successful planetary missions ever. Porco will review the fascinating data that Cassini and Huygens have sent us so far, which is providing unprecedented understanding of a remote planetary system. She will also preview for us the findings that are yet to come, which will further deepen our understanding of this distant, softly-hued planetary neighbor. And we'll see some stunning planetary images. Buckle your seat belts.
4 p.m. to 5 p.m.
VIRTUAL WORLDS AND WEB 3D
Tracy Kennedy, Research Consultant in virtual and physical worlds, and Ph.D. candidate in sociology at the University of Toronto.
NOTE: Tracy Kennedy was unable to attend due to scheduling conflicts. You can see her presentation here.
In 2003, Linden Research launched the virtual world Second Life, with only a small community of residents. Now there are almost 9 million registrants. Kennedy will tell us about Second Life and examine its appeal. This interactive, three- dimensional world has given rise to new leisure and social activities, business and marketing ventures, educational opportunities, political campaigns, arts, entertainment nearly everything that's available in the physical world. Of special note to science writers, Second Life offers a broad array of virtual magazines, news sites, and television stations. (Create an avatar to do your writing for you?) Kennedy will, however, include a cautionary note: Virtual worlds are not inherently utopian. With new worlds come social problems of the kind we're familiar with in the real world. She'll tell us about current research on social norms and behavior in virtual worlds; the future of virtual worlds; and whether Second Life is a passing fancy or the harbinger of what's now being called Web 3.0, or Web 3D.

ALL-DAY BONUS TOUR OF THE MANHATTAN PROJECT'S HANFORD SITE. The U.S. Department of Energy's 586-square-mile Hanford Site, in south-central Washington State, once produced plutonium for the nation's atomic weapons. The plutonium production left, in its wake, contamination that is now the focus of one of the world's largest environmental restoration projects. Workers are cleaning up a lethal soup of radioactive and chemical waste left over from years of plutonium production. The tour will feature a visit to the world's first full-scale nuclear reactor, known as B reactor, built as part of the Manhattan Project. And we'll enjoy a working lunch.
