    The Secret Lives of Roots

    Location: 

    Hunnewell Building, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    The Arnold Arboretum is full of spectacular specimens from around the world that any visitor will appreciate. However, what they observe is only half the story. How a tree uptakes water and nutrients, stays grounded in place, stores energy, and sometimes even propagates itself, is all thanks to its roots. Join horticulturists Andrew Gapinski and Conor Guidarelli as they unearth these questions and more during an exclusive look into the extraordinary world of roots.

    Introduction to Bonsai

    Location: 

    Hunnewell Building, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    Bonsai is the ancient Japanese method of growing and caring for a tree whose growth is restricted by the size of the shallow pot in which it is planted and by the pruning of its branches and roots. In this class, Glen Lord, who consults for the Arnold Arboretum’s bonsai (Japanese) and penjing (Chinese) collection of dwarf potted plants, will speak first about the history of bonsai. He will then demonstrate the methods employed in creating and caring for a bonsai. Participants will plant a tropical specimen and learn about basic pruning, styling...

    The First 25 Years: How the Arboretum Became the Arboretum

    Location: 

    Centre Street Gate, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    The Arnold Arboretum did not come into existence full-formed, but had a long adolescence before it (literally) blossomed at 50. Our first director, Charles Sargent, prepared a 50-year report in 1922, before the end of his own 54-year tenure. But, what about the first 25 years? We don't have a 25-year report, however, we do have photos and the engaging stories from that time.

    Join our docent to hear those stories, as she takes you on a timeline...

    The Undiscovered

    Location: 

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge, MA

    To paraphrase Louis Pasteur, sometimes luck favors the prepared mind, as when Alexander Fleming discovered penicillin by noticing that mold growing accidentally in his lab seemed to kill bacteria. This 2018 Radcliffe Institute science symposium will focus on how scientists explore realities they cannot anticipate. Speakers from across the disciplines of modern science will present personal experiences and discuss how to train scientists, educators, and funders to foster the expertise and open-mindedness needed to reveal undiscovered aspects of the world around us.

    Small Trees for Small Spaces

    Location: 

    Hunnewell Building and Landscape, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    Urban and suburban planting spaces are often constrained, often not ideal for accommodating a large oak, linden, or maple tree. But there are many smaller tree species that will thrive in a smaller space and won’t overwhelm the area. Some trees are cultivars that have been selected for their smaller size or narrow characteristics, while others are naturally genetically petite. Guided by the “right plant, right place” philosophy, Laura Mele...

    Quantum Tools to Explore the Universe…and Help Life on Earth

    Location: 

    60 Garden Street, Phillips Auditorium, 60 Garden St, Cambridge, MA 02138

    At the Center for Astrophysics, we exploit quantum physics to advance the state-of-the-art in measurement and imaging, and then apply these tools to search for Earth-like planets around other stars and probe the nature, history, and fate of the Universe. Sometimes, these quantum tools can also be applied to down-to-Earth problems — ranging from health to navigation.

    Saving Coral Reefs in the Florida Keys

    Location: 

    Geological Lecture Hall, 24 Oxford Street, Cambridge MA

    James W. Porter, Josiah Meigs Distinguished Professor Emeritus, Odum School of Ecology, University of Georgia

    Coral reefs support more than a quarter of all marine life, yet many are critically endangered. In the Florida Keys, the once common elk horn coral (Acropora palmata) has experienced steep declines since the 1970s. Preliminary blame was attributed to global warming and coral bleaching, but in fact, a human bacterial pathogen associated with a wide range of serious infections was the culprit. James Porter will discuss how Key West residents are saving these reefs...
