Regeneration is a remarkable phenomenon in which an animal can regrow parts of its body that are lost or damaged by injury. Humans, for example, can repair some organs, but some animals can rebuild their entire bodies from small pieces of tissue. How do these animals accomplish this feat? And why is it that humans cannot regenerate as well as these animals can? Studies of how regeneration works at the molecular and cellular level are beginning to answer the first question. To answer the second question, we have to understand how regeneration has evolved.
Animals develop special characteristics that help them survive in their environments. From keeping warm to staying hidden, animals solve problems every day. Have you ever thought about how we humans do the same?
Get ready for a lively night of fun, games, and surprises when Javier Marin transports you back inside the Harvard Museum of Natural History.

Visitors to the Harvard Museum of Natural History are dazzled by the Mineral Gallery’s beautiful specimens, yet the gallery displays only a fraction of the entire collection.
While each of the collection’s 300,000+ specimens has great scientific value, a subset also has significant commercial value. Join Curator Raquel Alonso-Perez for a virtual behind the-scenes visit to view specimens that, for security reasons, are not typically on display. You’ll see a rare opal in matrix from Mexico, tourmalines from the first pegmatitic discovery in the U.S., and crystalline gold, among...
Beech leaf disease (BLD) affects and kills both native and ornamental beech tree species. It is associated with a nematode, Litylenchus crenatae mccannii. This disease has only been discovered in recent years and much about it, including the full cause and how it spreads, is still unknown. Experts from The Connecticut Agricultural Experiment Station, Drs. James LaMondia and Robert Marra, will share what is known of this recently discovered disease and discuss ongoing research to control spread of BLD. This free Zoom webinar is co-hosted by Bartlett Arboretum & Gardens and the Arnold...
This is the third lecture in the Arnold Arboretum's 2021 Director's Lecture Series. Tiya Miles takes up the pecan tree as inspiration for exploring the meaning of trees in the lives of enslaved African Americans. Using a family heirloom, slave narratives, oral histories, and missionary records, her talk underscores the importance of trees in the Black experience of captivity and resistance, ultimately revealing the centrality of the natural world to Black, and indeed human, survival.
At the time of its founding in 1872, the land on which the Arnold Arboretum of Harvard University is sighted was a patchwork of farmland and forest. As the Arboretum was planted, pathways were developed to lead people through the picturesque landscape. As the landscape developed, economies shifted, wars took place, and directors changed. Each of these factors subtly influenced shifts in the park’s path system. Join the Arnold Arboretum on Zoom with Jared Rubinstein as he reveals the layers of change in this beloved landscape.
Have you ever thought about the way you eat, or even how you chew? Now, imagine that you are a huge bullfrog, a sea star, or even a scorpion. How would you eat? As March is Nutrition Month in the U.S., it’s the perfect time to meet some of our live animals and explore our creatures’ diets and eating habits. Join human museum staffers Javier and Ryan in this 45-minute program for families and get a close look at some weird eaters.
Participate in the Arnold Arboretum’s 2021 Tournament of Trees! Get to know this year’s Sweet Sixteen contenders (March 3–9) and cast your votes in this fun bracket style tournament. Let the March Tree Madness games begin.
Join us for a casual evening of conversation with the Peabody Museum’s Curator of Oceanic Collections. Ingrid Ahlgren stewards one of the largest and most historically significant collections in the U.S. from the Pacific Islands, Australia, and Aotearoa/New Zealand. Hear her share some of her recent work, including the exhibit Uncovering Pacific Pasts and the important roles that Harvard University and the state of Massachusetts have played in the history of Oceania. Ingrid will also discuss her upcoming collaboration with Pacific Islanders living in Utah.
Nature has long inspired we humans to imagine and create art. Dancers, designers, musicians, painters, and sculptors—they are all found in the natural world. Take this virtual journey through the exhibit galleries of the Harvard Museum of Natural History, where we will reveal intriguing, and often surprising, sources of creativity and connection between the realms of nature and art.
Shed the winter blues and head outdoors for a new season of exploration and nature noticing. EverydayNature Tasks, a calendar with daily activities to try outdoors, resumes its offerings on March 1. Do something natural every day! Free and open to all.
A plant that generates heat and attracts pollinators with its stink? Learn more about skunk cabbage in the Arnold Arboretum’s newest winter Wonder Spot, at the Arboretum meadow’s edge or online. Free and open to all.
Five decades of weekly walks in the Arnold Arboretum find expression in Ginny Zanger’s art. “Ambling” gives her time to sketch and paint. Using the unique possibilities of her favorite medium—watercolor—and printmaking, Zanger explores, with articulate interpretations, the Arboretum’s rich botanical display. In this online show, most of her work is on Yupo, a silky, polypropylene paper that enhances the flow of the watercolor.
Arnold Arboretum propagator Sean Halloran will provide an overview of dormant season grafting principles: reasons to graft, how it works, and the materials and environment required for success with this propagation technique.
Break out of the winter doldrums and welcome Harvard science into your home with the all-virtual I Heart Science festival lasting from Friday, February 12 to Monday, February 15. This day’s “Tiny Creatures” theme looks at bacteria, viruses, and other microbial creatures.
During the live webinar, starting at 1:00 pm ET, meet live tardigrades, also known as water bears. Watch recorded videos featuring Harvard scientists who study bacterial resistance, ways to test for viruses, and how bacteria grow.
At home, try your hand at making a water-drop microscope, comparing...
Artist and Harvard University alumna, Ginny Zanger, continued her decades-long weekly visits to the Arnold Arboretum throughout this past year. Here, she found a new and needed “sanctuary.” As she observed and recorded nature’s beauty, quiet, sublime images resulted, echoing the respite and spirit she found.
Joan Fitzgerald, Professor of Urban Planning and Policy at Northeastern University, will build on key concepts in her new book, Greenovation: Urban Leadership on Climate Change (2020). She’ll discuss how cities are rethinking their approach to climate action by placing racial justice at the forefront. She’ll draw from recent experiences with Providence, Austin, and Oakland in creating participatory planning processes and new priorities for a just transition to a carbon-free society. She’ll conclude by discussing how the transition can be linked to jobs in the green economy.
Students have been digging up and learning about Harvard's past through the Harvard Yard Archaeological Project. Meet the Peabody's Trish Capone and current Harvard student Nam Hyun Kim as they talk about the objects they have found and the larger history of what has been uncovered in this long-standing dig on campus.
Humans are living longer lives than ever before and so it is critical to understand the process of aging. It has become increasingly recognized that successful aging is not just about physical health but also about our social lives.
Chimpanzees are our closest living relative and also lead long and complex lives. In this talk, you’ll learn what chimpanzee aging can tell us about human aging.
Peter Del Tredici, Senior Research Scientist Emeritus at the Arnold Arboretum, and Rosetta Elkin, Associate Professor of Landscape Architecture at McGill University, converse about the nature of urban environments. Peter will begin the program with a brief overview of the plant observations he makes in his book, Wild Urban Plants of the Northeast. Following this, Peter and Rosetta will discuss both ecological and design elements that come into play in the cities and suburbs that we call home. Up for discussion are the environments that humans intentionally and unintentionally...
