    Old and New: Herbarium Vouchers and the Plants They Came From

    2:00pm to 3:30pm

    Location: 

    Arnold Arboretum, 125 Arborway, Boston

    The Arboretum's Herbarium contains over 100 thousand dried and preserved plants, and almost half were taken from the Arboretum's own collections. These Herbarium specimens offer a blast from the past for these historic trees, and this unique program offers a chance to see both ends of the timeline: we will begin inside the Herbarium with a look at historical specimens from decades ago, and then head outside to see the trees they grew into.

Understanding the structure and function of a tree's root system will not only help the audience become better gardeners but will enhance their appreciation of how forests work.

    Astronauts: Women on the Final Frontier

    7:00pm

    Location: 

    Center for Astrophysics | Harvard & Smithsonian—Online

    The first person who will set foot on Mars is alive right now. We believe this, but even if we're wrong we know the first crew to arrive there will look nothing like the ones that landed on the Moon fifty years ago.

    Our world has changed for the better, and ASTRONAUTS tells the story of the women who built this better world. The main character and narrator is Mary Cleave, an astronaut you may not have heard of. It's not because so many people have been to space; only a few hundred have! It’s because this graphic novel isn’t about fame. No astronaut you'll ever meet took the...

    Saving Coral Reefs in the Florida Keys

    6:00pm

    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...
