Friday, July 24, 7:00 pm – Unprocessed

In the tradition of Michael Pollan’s bestselling In Defense of Food comes this remarkable chronicle, from a founding editor of Edible Baja Arizona, of a young woman’s year-long journey of eating only whole, unprocessed foods–intertwined with a journalistic exploration of what “unprocessed” really means, why it matters, and how to afford it.

In January of 2012, Megan Kimble was a twenty-six-year-old living in a small apartment without even a garden plot to her name. But she cared about where food came from, how it was made, and what it did to her body: so she decided to go an entire year without eating processed foods. Unprocessed is the narrative of Megan’s extraordinary year, in which she milled wheat, extracted salt from the sea, milked a goat, slaughtered a sheep, and more–all while earning an income that fell well below the federal poverty line.

What makes a food processed? As Megan would soon realize, the answer to that question went far beyond cutting out snacks and sodas, and became a fascinating journey through America’s food system, past and present. She learned how wheat became white; how fresh produce was globalized and animals industrialized. But she also discovered that in daily life, as she attempted to balance her project with a normal social life–which included dating–the question of what made a food processed was inextricably tied to gender and economy, politics and money, work and play.

Backed by extensive research and wide-ranging interviews–and including tips on how to ditch processed food and transition to a real-food lifestyle–Unprocessed offers provocative insights not only on the process of food, but also the processes that shape our habits, communities, and day-to-day lives.

Megan Kimble is a food writer living in Tucson, Arizona, and the managing editor of Edible Baja Arizona, a local foods magazine serving Tucson and the borderlands. She will appear at Porter Square Books, 25 White Street in Cambridge, on Friday, July 24 at 7 pm for a talk and book signing. For more information visit

Saturday, July 11 & Sunday, July 12, 10:00 am – 5:30 pm – Butterfly and Caterpillar Weekend

On Saturday and Sunday, July 11 and 12, meet an amazing array of native New England caterpillars in various stages of development, and learn more about caterpillars and butterflies through live presentations and interpretations throughout the Museum of Science.

On Saturday and Sunday from 10 – 3 there will be a Caterpillar Lab. This one-of-a-kind experience is a celebration of the impressive diversity of New England caterpillars. Each individual display includes a variety of caterpillars, in various stages of development and on their local host plants. With no glass between you and the displays, you can experience caterpillars up close — eating, pooping, camouflaging, or defending themselves with clever adaptations such as warning coloration, inflatable horns, strange smells, and squeaking mandibles.

From 1 – 3 on both days you may Create Your Own Butterfly Habitat. With your paid admission to the Butterfly Garden, learn how to create and plant your own butterfly habitat. We’ll discuss the importance of using native plantings and how to get your garden started. Get your hands dirty planting native seeds and take them home to help start attracting butterflies!

On Saturday at 11:30 hear Dr. Gerard Talavera from Harvard University describe the amazing migration of the Painted Lady butterflies, Vanessa cardui. Learn more about the challenging task of studying this beautiful insect, which is found on five continents. Also on Saturday, at 12:30, Dr. Naomi Pierce, curator of Lepidoptera at Harvard University, will introduce you to the insect-eating predators and their nourishing ant prey. Dave Champlin from the University of Maine unravels the amazing transformation of how the butterfly gets its wings on Sunday at 11:30, and finally, on Sunday at 12:30, Norah Warchola from Tufts University discusses the fascinating relationship between an endangered species of caterpillar and the ants that protect it from predators in exchange for a sugary bribe.

Also on Saturday and Sunday there will be presentations on Gardening for Butterflies at 1:30 in the Shapiro Family Science Live! Stage, Green Wing, Lower Level. As a bonus, The Secret Lives of Fireflies will be featured both days at 3:30 pm. Watching fireflies is a special part of warm summer nights in New England. We watch and we enjoy, but do we really know what they are saying? This program sheds a little light on the secret lives of fireflies. You’ll also learn how you can participate in a scientific research effort to find out if these magical insects are disappearing from our landscape, and if so, why and what can be done about it. Solitary Bees: The Other Bees will be discussed at 5:30 pm on Saturday and Sunday. Honey bees are in decline. Since they are responsible for pollinating one third of our food crops, their disappearance threatens our food supply. While scientists try to find out why and how to reverse this trend, our crops still need to be pollinated. Find out how you can help by becoming a “solitary beekeeper.”

While you are at the Museum, don’t miss Flight of the Butterflies at the Mugar Omni Theater each day at 1 pm. Weighing less than a penny, the monarch butterfly makes one of the longest migrations on Earth. Follow this perilous journey and join hundreds of millions of real butterflies in the remote mountain peaks of Mexico, with breathtaking cinematography from an award-winning team.

Thursday, June 25, 10:00 am – 12:00 noon – Beaver: Building Habitat, Improving Eco-Systems

Beaver are unique among mammals in that they alter their habitat to meet their needs by damming streams to form ponds. This behavior actually benefits other species (including people), as well. By building dams and flooding woodland swamps, beaver play an important part in the restoration of lost wetlands, providing habitat and food for a wide variety of plants and animals. Over 50 percent of our wetlands have disappeared since European settlement in North America. Beaver build their dams in order to create deep ponds that won’t freeze at the bottom in winter. Because of the flooding beaver create, trees often die off, providing nesting sites for great blue herons, wood ducks, tree swallows, and other birds. These new ponds become homes to amphibians, turtles, fish, otters, muskrats, and other animals.

Beaver-created wetlands also enhance human habitat by storing and slowly releasing floodwater, which controls downstream flooding. They improve water quality by removing or transforming excess nutrients, trapping silt, binding and removing toxic chemicals, and removing sediment. And finally, flooded areas can also recharge and maintain groundwater levels, and provide flow to streams even during droughts.

Join conservationist Cindy Dunn at Wachusett Meadow Wildlife Sanctuary in Princeton, Massachusetts, on Thursday, June 25, from 10 – noon, for this unique walking tour of the 85 acre beaver pond to learn about the important ecological role that beaver play. Wachusett Meadow is one of the spectacular wildlife sanctuaries within Mass Audubon. This property consists of 1,200 acres accessed by 12 miles of trails. The sanctuary protects a diverse landscape of shrubland fields and meadows, forests, Wachusett Meadow’s Wildlife Pond, and beaver wetlands. Rain or shine event. $22 for ELA members, $32 for non-members. Register at

In late June and early July they are at the height of their bloom, providing an exceptional opportunity for study, comparison, and enjoyment. Linden flowers attract pollinating bees and appreciative visitors with their wonderful, enticing fragrance. Join The Arnold Arboretum on Meadow Road for a horticultural tour of the Tilia collection with Kyle Port, Manager of Plant Records at the Arboretum, and a tour focusing on honey bees with Heather Mattila, Assistant Professor at Wellesley College, whose research focuses on the mechanisms of honey bee behavior, the chemical ecology of colonies, and the microbiology of queens and workers. There will also be fun family activities focusing on the lindens. The event takes place from 1 – 3 on Sunday, June 21. Collections Up Close events offer great ways to explore plants at the Arboretum. Free – no registration required.  Image from
