• Science Spotlights: The Case of the Immortal Chemicals & Learning about the Deep Past from Ancient DNA

    Harvard Museum of Natural History 26 Oxford Street, Cambridge, MA, United States

    Meet up-and-coming scientists and learn about questions at the forefront of research today in this series of short talks.

    2:00–2:30 pm – The Case of the Immortal Chemicals
    Speaker: Ethan Sontarp, Graduate Student with the Sunderland Group

    There’s a mystery that needs to be solved: where does invisible pollution go when it is released into the environment? Scientists use chemical fingerprinting to do detective work, uncovering why certain man-made pollutants are so resistant to breaking down and where they like to go. By following this trail of clues, researchers can learn how to stop pollution from entering our food and drinking water. Join Harvard scientist Ethan Sontarp to discover how environmental detective work can help protect the world around us.

    3:00-3:30 pm – Learning about the Deep Past from Ancient DNA
    Speaker: Daniel Tabin, PhD Student in the David Reich Lab

    Writing has only been around for about 6,000 years. This means that the stories of people who lived before that time were never recorded for future generations. Thankfully, these stories are not lost forever. How can we learn about the adventures, relationships, and challenges of people who lived long before anyone ever put words on a page? Join Harvard scientist Daniel Tabin to discover how ancient DNA can help us piece together the lives of people who lived thousands of years ago—and hear about the remarkable stories he has helped bring back to light.

    20-minute talk followed by 10-minute Q&A session. Recommended for ages 10 and up.
    Regular museum admission rates apply.

    Presented by the Harvard Museum of Natural History and Harvard Museums of Science & Culture

  • “A Fresh Start for Our Cities” featuring Bill McKibben ’82

    PIPER AUDITORIUM, GUND HALL 48 QUINCY ST. CAMBRIDGE

    For over 40 years, Bill McKibben has been raising the alarm about the climate crisis, starting with his groundbreaking book, The End of Nature. Now McKibben says, for once in his life, he is spreading good news. In his latest book, Here Comes the Sun, he explains why the recent boom in solar and wind power has given him hope for the planet's future, and he implores everyone to buy in. We hope you can join us for this inspiring and important conversation. This event is supported by the Melissa Kaish and Jonathan Dorfman Makers Fund. It is co-sponsored by the Salata Institute for Climate and Sustainability through its Climate Crossroads: Debating Energy’s Next Frontier series, bringing leading voices confronting the intertwined challenges of climate change and the global energy transition to Harvard University.

  • Research Spotlight: Building with Fungi (for Arnold Arboretum members only)

    Flora Way Gate Flora Way, Boston, MA, United States

    Fungi are known for their decomposing properties, but did you know that also make great building components? Dehydrated fungal mycelium is waterproof, fire retardant, insulating, and sound absorbing, and GSD post-doc Noam Attias is on the hunt for new species of fungi in the Arboretum to create the next generation of eco-materials. Join Noam for a walk in the landscape highlighting her work and learn about the Arboretum fungi she is exploring.

  • ‘Asunder’ and the California Wildfires

    Arnold Arboretum

    The devastating wildfires in California over the past several years have left the landscape starkly and in many cases permanently changed. Billie Mandle, Photography professor at Massachusetts College of Art and Design, and Karen Haas, Curator of Photography at the MFA, come together to talk about Billie’s new photography book ‘Asunder,’ made up of stark and haunting photos of the aftermath of the 2020 Glass Fire in Northern California. They will be joined by Director of the Harvard Forest Jonathan Thompson who will share his research on how the wildfires have changed the very makeup of California forests, from mature trees to landscapes dominated by chaparral.

    Join us for this unique panel talk that mixes science and art to look at some of the most devastating natural disasters of the past decade.

  • Animal Law Week Day 2: “False Food Promises and Farmed Animals—Green-Washing in Food Law: The Case Against JBS”

    WCC 1010, 18 EVERETT STREET, CAMBRIDGE

    When global meat producers market themselves as environmentally friendly, how can we separate fact from fiction?
