Science Cafe: A Problem So Small You Can See It From Space

Do we really consume a credit card’s worth of microplastics in a week? That depends largely on how you measure it. But one thing is certain: microplastics are all around us and they’re here to stay.
These plastics may be small, but understanding their impact requires research at all scales. Zooming in, microplastics are not solo actors: they host an array of plastic-associated microbes that could be unexplored reservoirs of pathogens and antibiotic resistance genes. Microbes also degrade plastic. Zooming out, the extent of the microplastic pollution in our waterways could be detected from space using remote sensing technology.
Please join Chris Ruf, Principal Investigator of the Remote Sensing Group (RSG) in the Climate and Space Sciences and Engineering Department (CLaSP) and graduate student Gopal Sundaram of the College of Engineering; Melissa Duhaime, Associate Professor in the Department of Ecology and Evolutionary Biology; and members of the Duhaime Lab (Rachel Cable, Lizy Michaelson, Skyler Har), for a discussion about one of our planet’s biggest tiny problems.

Science Cafe: Disinformation, Social Media, and Elections

Where do you get your news? How do "fake news" and social media affect your perspectives? New U-M research and scholarship can help us understand the widespread impact of disinformation and bias in our current ecosystem of social media and content sources.
Please join Ariel Hasell from the Communication and Media department, and Barbara McQuade of the U-M Law School, for a discussion about truth, trust, government, and how we can be effective and critical technology users and consumers. Professor McQuade has recently published the book: Attack from Within: How Disinformation is Sabotaging America, and books will be available for sale.

Science Café: The Future of MRNA Vaccines

We have seen how mRNA vaccines have changed the course of the COVID-19 pandemic, reducing the occurrence of severe illness and saving lives. What is the future of this biotechnology? Join Rachel Niederer and Nils Walter of the U-M Department of Chemistry and the Center for RNA Biomedicine to learn how mRNA vaccine technology could address influenza, Ebola, and other viruses—and even help fight cancer.

Science Café: Machine Learning and Artificial Intelligence

What is machine learning? Is it the same as artificial intelligence? Please join Raed Al Kontar of the U-M Department of Industrial & Operations Engineering to discuss how machine learning algorithms can be applied to distributed systems such as cars, phones, and hospitals, where data comes from many sources. 

Science Café: Politics and Power in Your Morning Coffee

Coffee production has a history as a colonial crop, destructive to the environment. Can coffee support biodiversity and local farms? What if we teach farmers how to grow coffee sustainably? What if doing so means opposing mega-corporations, or even advocating for political independence? Learn about new research and education efforts by two U-M scientists who are intent on revolutionizing coffee production to something sustainable that benefits local communities.

 

John Vandermeer (Ecology and Evolutionary Biology) and Ivette Perfecto (School for Environment and Sustainability) have worked with coffee production in Mexico, and are currently working in Puerto Rico. Learn about the obstacles to this important work - this conversation may change the source of your morning brew! Bring your coffee questions.

Science Cafe: High Tech Bones and Buildings

High-resolution 3D scans, prints, and renderings are changing the way scientists work! Please join Adam Rountrey of the U-M Museum of Paleontology and Nic Terrenato of the Kelsey Museum of Archaeology for a look at the research and educational opportunities made possible by 3D imaging and printing.
With accurate digital "copies" available, are the original objects more or less important? How should 3D research data be shared and preserved? Can these copies make repatriation easier? What about equitable access to collections? Enjoy a presentation and casual conversation on the changing nature of historical sciences.

Science Cafe: Policy from the Pulpit? Influences on Climate Change Skepticism

Climate change action is one of the most urgent questions we face. What influences public opinion on this issue? Recent research has shown that religious affiliation is not a consistent predictor for climate change skepticism. The exception to this rule is evangelical protestants who consistently poll as more skeptical than the general population. Do local evangelical ministers fit the trend of this larger demographic, or is there more to the story? Join Buddy Stark (Ph.D. student with the Mallinson Institute for Science Education at Western Michigan University) to discuss how the belief structures leading to skepticism among evangelicals are more complex than we might predict. We'll consider what approaches might be useful in moving us all forward.
Buddy Stark is the planetarium manager at the U-M Museum of Natural History.

Pollinators

Pollinators play a vital role in our food systems and are crucial to preserving the areas across the world being threatened by climate change and industrialization, but it takes more than just planting flowers to protect our pollinators.

In this episode, Dr. Michelle Fearon will walk us through the basics of pollination and pollinator health, former U-M Horticulture Supervisor Bill Kronberg will explain how the University is engaging in pollinator health through its new Bee Campus USA certification, and Matthaei Botanical Garden’s Natural Areas Specialist Steven Parrish will speak on what you can do in your very own backyard. Join host Lindsay Gooch as she speaks with these industry professionals to uncover and understand the complex and incredibly interesting world of pollinator health.

Science Cafe: Extreme Science! Dark Matter and Dark Energy Research

Sometimes scientists must go to the ends of the earth, and even deep underground, to see the unseen! Join us and meet two charismatic researchers from the U-M Department of Physics who do just that. Bjoern Penning studies dark matter a mile underground in the former Homestake gold mine in Lead, South Dakota, using Lux-Zeplin, the world's most sensitive dark matter experiment. Marcelle Soares Santos contributed to the construction of the Dark Energy Camera on a mountaintop in Chile, one of the largest telescope cameras in the world, which she now employs to search for gravitational wave-emitting collisions of neutron stars and black holes. Bring your physics questions for this exciting conversation!

Science Café: Climate Solutions: Renewable Energy Storage and Carbon Capture

How can renewables such as wind and solar energy produce power for use when the sun isn't shining or the wind ebbs? How can we capture the carbon dioxide that is already in the atmosphere?

Join Charles McCrory of the U-M Department of Chemistry and David Kwabi of the U-M Department of Mechanical Engineering to discuss new research on renewable energy storage: using renewable electricity to charge batteries and produce chemical fuels like hydrogen that can be used for later energy generation.

We'll also discuss how renewable energy may be used to mitigate climate change by capturing and storing atmospheric carbon dioxide, or converting it into useful products.
