    The Diffusion and Adoption of Welfare-Enhancing Innovations

    Location: 

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

    Todd Rogers is a behavioral scientist and professor of public policy at the Harvard Kennedy School. Using his two decades of work in behavioral policy as a base, he will discuss his current research into what leads to welfare-enhancing innovations and practices. In particular, he aims to help scholars and practitioners design, identify, and invest in innovations that are likely to successfully scale.

    This event is free and open to the public.

    Angiosperms and Gymnosperms: The Basics

    Location: 

    Centre Street Gate, Arnold Arboretum, 125 Arborway, Boston

    What better place to look for the differences between angiosperms (plants that flower and have enclosed seeds), and gymnosperms (plants with "naked seeds," including conifers, ginkgos and others), than in the Arnold Arboretum landscape, where over 15,000 plants reside in a living museum. Join the Arboretum's guide, Florrie Wescoat, as she points out trees in both groups and describes the characteristics of each.

    Lecture: Darkness in Distress

    Location: 

    Weld Hill Building, Arnold Arboretum, 125 Arborway, Boston

    Join the Arnold Arboretum for a lecture by science journalist Kelly Beatty. Light pollution, simply put, is any unnecessary or excessive outdoor illumination. Sadly, it’s become a pervasive and ugly consequence of modern 24/7 society. Light pollution robs us of the night sky’s beauty, negatively affects the ecosystem, and creates an in-your-face waste of energy. But a new mindset and new technology are poised to slow—and perhaps reverse—this bane of modern life.

    Exhibition Opening: Measure

    Location: 

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge, MA 02138

    Anna Von Mertens is an exhibited artist who uses the structures of quilting and drawing to explore the frontiers of human understanding. Her new exhibition "Measure" explores the life and work of Henrietta Leavitt, one of the women “computers” hired to study glass-plate astronomical photographs at the Harvard College Observatory a century ago. Leavitt’s findings provided a unit of measurement for galactic distances. Reimagined in meticulous stitches and intricate graphite marks, Von Mertens examines our current understanding of the size and shape of...

    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.

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge, MA 02138

    The Next in Science series provides an opportunity for early-career scientists whose creative, cross-disciplinary research is thematically linked to introduce their work to one another, to fellow scientists, and to nonspecialists from Harvard and the greater Boston area. The focus of this year’s program is in the study of evolution. In this program, two leading researchers will explore the genetic impact of Neanderthal interbreeding with modern humans and consider how people migrated, adapted, and mixed over the course of human history. Two...

    Sharon Hessney, Writer and Moderator of New York Times Learning Network "What's Going On in This Graph?"

    Graphs can go a long way in conveying information that might otherwise take several paragraphs to explain. But it is easy to misread or not fully understand the content and context. In this participatory program, we will decipher several graphs based on data from Arnold Arboretum curators and scientists. We will also look at the data...

    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...
