Is Fracking on the Horizon? Feeling Our Way to An Energy Future

What's the first thing that comes to mind when you hear the term "fracking"? Your opinion on this new energy technology may depend on the image that first springs to mind. Drawing a blank? Take heart: A recent study found that nearly 40 percent of those surveyed had never heard of fracking. However, that same study identifies this new technology as a likely cornerstone of the nation's energy future. In hydraulic fracturing, or fracking, millions of gallons of water mixed with chemicals are injected deep into the earth at high pressure in order to fracture rock, releasing otherwise inaccessible natural gas or oil. The weight you give to the risks of fracking (environmental, social) and its benefits (economic) are influenced by a range of factors. Gender, age, income, education all play a role – but so does worldview, and it seems that we literally "feel" our way to an opinion. Do Vermonters feel differently from New Yorkers or Pennsylvanians about fracking? What affects the way we feel about wind farms or the Northern Pass? Do these feelings change over time? Public opinion plays an important role in our energy policies. How do we decide? This is your turn to ask!

Extinctions: How Astral Collisions Have Affected Life on Earth
Thursday, May 22, 2014

Encounters with comets, asteroids and meteorites are a staple of science fiction, and though humans no longer believe these astral events to be messages from the gods, we are fascinated at their doomsday potential – at least for anything in their paths. A space rock that hit Earth 65 million years ago is thought to have wiped out the dinosaurs. Was that space rock a comet or an asteroid? How do we know, and what is the difference between these near-Earth objects? Another astral impact about 13,000 years ago is believed to have triggered a dramatic climate shift globally, with far-reaching effects on both animals and humans. Why were larger mammals affected by these collisions? Are humans at risk of species extinction from a future astral collision? This is your turn to ask!

Happiness: A Good Thing, Right?
Tuesday, April 22, 2014

The framers of the US Constitution thought the "pursuit of happiness" to be so fundamental an instinct that they listed it along with "life" and "liberty" as an "unalienable right" of all humans. So how is it that some people seem persistently happy while others seem chronically glum? Is it nature, nurture, fate? Brain science researchers have evidence that a person's happiness is related to his ability to regulate positive and negative emotions. What is happening in our brains when we are happy? Can we learn to be happier? Do we get better at it as we age? Is there a down side to happiness? This is your turn to ask!

The Aurora-Wonder of the Night Sky
Thursday, March 27, 2014

The colorful dancing lights in night skies known as the Aurora have long fascinated humankind, inspiring ancient legends and speculation by philosophers. Aurora was the Roman goddess of dawn, and Aurora Borealis - the lights in the northern hemisphere – is Latin for "dawn of the north" while Aurora Australis – lights in the southern hemisphere - means "dawn of the south." Appearing in myriad forms, from colored arcs and streamers to clouds and curtains of light, the night display we New Englanders know as the Northern Lights is caused by the collisions of charged particles traveling on solar winds that become trapped in magnetic fields around the Earth's poles. What causes the variation in the bright colors pulsing across the night sky? What can the Aurora tell us about geomagnetic storms and what effect do those storms have on our satellite systems, telecommunications and power grids? When and where are we most likely to see the Northern Lights? This is your turn to ask!

Tomorrow's Energy: Challenges and Choices
Thursday, February 20, 2014

Civilization continually adapts to changes in the environment, resources and technology. Historically we have transitioned from hunter-gatherer to agricultural to industrial societies that are no longer sustainable. We now face an unprecedented rate of change challenging us to move to a sustainable industrial society. Energy is at the core of the challenge. Experts are working on global, regional, and local scales to address our energy issues but each success has unintended consequences, both positive and negative. What must we consider as global citizens facing these challenges? What are the regional issues we face in New England as we look at alternatives such as wind and biofuels? What are municipalities and citizens groups in the Upper Valley doing to implement renewable and low cost energy solutions locally? This is your turn to ask!

How Resilient Are We? Coping When the Forecast Says Change
Thursday, January 23

Changing weather patterns, melting ice caps, rising seas, and extreme storms are some of the obvious signs of climate change. Many communities are dealing with these effects along with a novel suite of social and economic disturbances of a similarly global origin. Water supplies, public health, farms, fisheries, and natural ecosystems are just a few of the critical areas of concern on a global and regional scale. Governments and citizen groups around the world are addressing agricultural practices, social policies, and re-designing infrastructures to adapt to the changes they are experiencing. What do we know about how institutions and governments adapt to rapid, profound change? What can we learn from those who are already adapting? Are there specific issues of concern for Upper Valley communities? Who is addressing them? This is your turn to ask!

The Promises and Limits of Local Food
November 20, 2013

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?

Our Changing Climate: Bringing It Home
October 17, 2013

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?

What's That in the Water? How Algae and Other Unwelcome Blooms are Affecting our Waterways
Thursday, September 26, 2013

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?

Arctic Meltdown? The Science and Politics of Polar Environmental Change
Thursday, May 16, 2013

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.

The Mysteries of Memory: When We Can't Remember or We Can't Forget
Thursday, April 18, 2013

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!

Unwanted Dead or Alive: Can We Save Our Forests from Invasive Pests?
Thursday, March 28, 2013

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.

Black Holes: Monsters of the Universe
Thursday January 17, 2013

The universe is teeming with galaxies, magnificent star systems held together by strong gravitational forces. At the center of most large galaxies is an exotic phenomenon we can't see — a supermassive object called a black hole whose gravitational forces are so powerful that nothing, even light, can escape from its pull. Just what are these mysterious objects? If they are invisible, how do we know they exist? Are we in danger of being gobbled up by a black hole? What would happen to you if you fell into one? What would others, watching from a safe distance, see? Come with your cosmic curiosity to ponder these questions, and learn more about how you can further explore our amazing Universe.

The Dope on Steroids: Great for muscle, but how about your brain?
Thursday November 15, 2012

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?

Pollinators in Peril: What pollinator decline could mean for food security and ecosystem health
Thursday October 18, 2012

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!

The Secret Life of a Scientist: What do they actually DO?
Thursday Sept 20, 2012

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!

Genes R Us – Aren't They?
Thursday, April 26,2012

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?

Smart Phones Today, Smarter Societies Tomorrow?"
Thursday, February 9, 2012

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?

Stormy Weather: Is Climate Change Here?
Thursday, November 17, 2011

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.
