Thirsty for a good conversation in a comfortable atmosphere? Do you have questions you would like to ask a scientist or would you just like to sit back, relax and learn something new about the world? Come to a Science Pub for an open, thought-provoking, easy-to-understand discussion.
Based on the Science Cafe model developed in Europe in the 1990s, Science Pubs at Salt hill bring scientists and the public together for informal discussion around topics relevant to your world. A Science Pub is not a lecture but is a good conversation. Enjoy your refreshments or dinner while engaging with your community and local scientists and experts.
These public events are open to all and are held at the Salt hill Pub, 2 W. Park St., Lebanon, NH from 5:30-7:30 pm. The 2013-14 Science Pub season will begin in September and we will meet the third Thursday of most months through May.
Brought to you by Dartmouth College Office of Science and Technology Outreach and Salt hill Pub, Lebanon, with support from NASA.

The local food movement has mushroomed across the US, as many are persuaded that buying locally, even if it costs more, is the ethical choice. Many people assume that shortening the distance from farm to table both lowers the environmental impact of the food we eat and increases its social benefit, by supporting nearby small farmers rather than distant industrial producers. But are these assumptions valid? Is eating locally more ethical even if, as some research shows, it is not always better for the environment? Do nearby farmers deserve our dollars more than distant ones? Does buying their food have other benefits, such as for animal welfare? Can we really "vote" for a better, more sustainable food system through what we choose to eat?

We've all heard the predictions – warmer average temperatures, earlier and wetter springs, less snow. But exactly how will those climate change predictions affect the Upper Valley our grandkids experience? Certainly diminishing snowfall will affect the ski industry – but does snow represent other values for New Englanders? Scientists say it does, and one reason for that is something called albedo. Its literal meaning is whiteness, and it describes the complicated feedback loops involving reflected snow. Will our grandkids climb maple trees or will we learn to love birch syrup? How will our forests and land use change? Will spring still bring the sound of the wood thrush? Will the tomato-growing season get better?

Call it a boom, call it a bloom – in the ecosystem of a lake or river, a sudden increase in the population of one tiny organism can mean trouble. For example: blooms of Didymo, an algae appearing in Upper Valley rivers, has acquired the nickname of "rock snot" for its slimy appearance on the stream bottom of pristine rivers. A threat to fish - and to many aquatic organisms - there is new evidence that these blooms may not be spread, as commonly believed, by fisherman carrying the algae on felt-soled boots. Lakes in the Upper Valley are also seeing blooms of cyanobacteria, often referred to as "blue-green algae," that can give clear water the appearance of thick, foamy pea soup. Overgrowth of the microorganism also reduces healthy oxygen levels in the water and produces toxins that may be linked to some neurological disorders. Scientists who study New England's rivers and lakes are investigating the causes of these blooms and how they threaten invertebrates, fish, waterfowl, the water we drink, and recreational opportunities on local waterways. What conditions are causing these blooms and what is the forecast for the future? What are the long-term effects on humans, animals, our waterways? How can we keep these microorganisms in check or adapt to these changes?

Since the 15th century, finding a northwest passage linking the Atlantic and Pacific Oceans was a romantic and heroic quest for maritime explorers. But the formidable barrier of sea ice pushed into the ocean from the Greenland Ice Sheet closed the passage off for much of the year. In recent years, the shrinking of the icepack in the Arctic is opening the Northwest Passage for the longest periods on record, creating new opportunities for commercial navigation. However, other effects of climate warming in the region are of great concern to scientists and inhabitants of the Arctic, with widespread political, economic and environmental consequences for people all over the globe. How do geological records of past glacial advance and retreat help us understand changes we see today? How can we untangle the signal of human activities associated with warming from the noise of natural variation? Where and when will the effects of climate warming in the Arctic be observed in our region? What are the political consequences of the opening of the Northwest Passage? Bring your curiosity and questions to this timely conversation.

Some would argue that memory makes us who we are. Certainly our memories of people, places and procedures help us navigate daily life, and memories of past experience provide meaning and context to the present. But why do some memories elude recall while others persist? What can we do to improve our memory? Are there ways to help erase traumatic memories we would rather not revisit? New research is finding answers to both of those questions and, surprisingly, the story of memories lost and memories impossible to forget involves the stress response. Do you have other questions about memory? This is your turn to ask!

Imagine an alien invasion of New England, requiring every maple tree to be cut down, town by town. Science fiction? Not at all, as residents of Worcester, Massachusetts can tell you. In 2008, a wood-boring beetle with a taste for hardwood rapidly infested maple trees there requiring 29,000 trees in the city to be cut down in an effort to stem the spread. Scientists warn that the Upper Valley is vulnerable to a similar fate, with devastating consequences for fall foliage, maple syrup, our lush green landscape and the economy of New England.Why is this happening? What can we do? Come join us for a lively discussion about the science of invasive insects and strategies for protecting our forests.

It's a tempting proposition for an athlete: To increase your stamina and strength, to build muscles faster than workouts alone, just take a pill! That's the promise of anabolic steroids, synthetic hormones that give athletes a competitive edge. But along with those benefits come some serious risks: infertility, behavioral changes, and cancer. There are particularly concerning effects on adolescents. Steroid use has been banned by most major athletic associations, yet news accounts of "doping" continue to appear. Should kids and adults be "allowed" to play by different rules when it comes to taking steroids? As parents, are we unwittingly sending messages to our children that make steroids more appealing? What roles do school coaches and team members play?

Declining numbers of bees and other pollinators are raising concerns among scientists and farmers: could decreased pollination affect the world's food supplies? Researchers have been investigating factors affecting bee populations: pesticide use, habitat loss, disease and — most recently — a climate-change driven mismatch between the times when flowers open and when bees emerge from hibernation. What is the difference between native bees and managed honeybees? Why is the health of both important to the diversity of our landscape and local food crops? This is your turn to ask!

There is good evidence that most of us have a skewed understanding of who scientists are and what they do. The stereotype: a white male with glasses and wild hair wearing a lab coat, bubbling test tube in hand. What are the consequences of this cultural stereotype – and what is the reality? Are scientists super-smart experts on all things science? Do they work alone in those labs? How has the practice of science changed over time? Exactly what do scientists do all day? This is your turn to ask!

Over the past 15 years, billions of tax dollars have supported the Human Genome Project, an effort to identify the entire genetic blueprint of the human being. Understanding how your genes may predispose you to a wide variety of diseases is a good thing - isn't it? Stop by your local grocery, buy a home test kit, swab the inside of your cheek and send it off for genetic testing. But wait: 3 billion pieces of information that could affect you and your future, your children and family, your employment and insurance. How do you know what to do with those test results? Can your doctor help? Who else will see them? What are the benefits of knowing the details of your unique genome? What are the ethical considerations?

Science fiction has often raced ahead of science in predicting how future technologies would change society - think Smell-O-Vision and personal Jet Packs. But when it comes to computing, growth has indeed been exponential. But what do we really know about these devices that surround us? Do you know what makes your iPad tick or what your smart phone and laptop have in common? How has your life been changed by these devices? How has your community changed as smart devices increasingly permeate our society? Are we too reliant on these devices?

For decades, scientists have been predicting that climate change would usher in an era of more intense and frequent storms and droughts. Was Irene an example or just a particularly bad rain storm? What do climate models predict for the next 25, 50, 100 years? How well can we really predict future weather patterns from these models? How are land use and settlement patterns in a community affected by flood events? Should we rebuild where we always have - or can moving development bring new opportunities for communities? What lessons can be learned from Irene?
Discussion leaders: Erich Osterberg, Research Assistant Professor in the Department of Earth Science, Frank Magilligan, Professor in the Department of Geography, both from Dartmouth College and Lori Hirshfield, Director of the Dept. of Planning & Development Services for the Town of Hartford, Vermont.
