  • s02e14: Dr. Kevin Peter Hand: Ocean Worlds of the Outer Solar System
    Where is the best place to find living life beyond Earth? It may be that the small, ice-covered moons of Jupiter and Saturn harbor some of the most habitable real estate in our Solar System. Life loves liquid water and these moons have lots of it! These oceans worlds of the outer solar system have likely persisted for much of the history of the solar system and as a result they are highly compelling targets in our
    search for life beyond Earth. Dr. Hand will explain the science behind why we think we know these oceans exist and what we know about the conditions on these worlds. He will focus on Jupiter's moon Europa, which is a top priority for future NASA missions. Dr. Hand will also show how the exploration of Earth's ocean is helping to inform our understanding of the potential habitability of worlds like Europa.

  • s02e13: Chris Lowe: Recovery of Large Marine Predators Off California Coast
    Urbanization and coastal development in southern California over last 100 years resulted in considerable impacts to the marine ecosystem through habitat loss, pollution, and overfishing. This stimulated substantial state and federal regulations over the last 40 years to reduce these impacts, particularly necessary with a growing human population. One indicator of ecosystem restoration can be seen in recovery of marine predator populations, including meso and apex predators (e.g. teleosts, sharks, seals, whales). While direct protection for many marine predator species have been in place for at least a decade, improved fisheries management, water quality and coastal habitat restoration have likely aided predator recovery.

  • s02e12: John Trumble: Climate Change, Insect Biology, and the Challenges Ahead
    Our climate is changing. C02 levels in the atmosphere are growing at unprecedented rates and temperatures are increasing so quickly that in less than one hundred years humans will be living on a planet that will be hotter than at any time in the evolution of the human species. Increasing concentrations of atmospheric C02 are already effecting insects and plants. Rainfall patterns are changing. These effects lead to series of critical challenges that we must overcome even as human populations are rapidly growing. Clearly, we must find ways to increase the global food supply. Among our biggest competitors will be insects. Climate change and global travel are enhancing the introduction of new agriculturally and medically important insects into natural and agricultural systems. Some of these movements are predictable and plans for their introductions should be made in advance. From a scientific viewpoint, the likely ecological changes in insect-plant interactions are fascinating. From a societal point of view, now is the time to begin training the next generation of agricultural scientists and farmers. Unfortunately, the current trend is for universities to cut back on agricultural departments, and many students do not find agricultural disciplines to be as exciting (or as profitable) as manufacturing, engineering, and the sciences that have taken us into space. We have to do a better job of showing our students how advanced and interesting agricultural sciences really are. Eventually the need for food will drive the need for more scientists and improved farming techniques, but unless we act on all of these challenges now, we risk falling too far behind to sustain either the population or our environment.

  • s02e11: Thomas Hull: Origami: How to do Math and Science Without Scissors/Glue
    Origami is the ancient Japanese practice of paper folding, where cuts are not allowed, to make intricate works of art that are sometimes minimalist and sometimes amazingly complex and realistic. The past 5-10 years have seen a surge of interest in origami for applications in engineering, physics, architecture, and other branches of science. Origami is being used to design solar sails that unfold without the aid of human hands in outer space. It is being used to design innovative heart stents, automobile airbags, and even micro-scale robots. Materials scientists are finding ways to fold everything from graphene to polymer gels to sheet metal. This presentation will describe how origami is being used in science, how mathematics has unlocked the power of origami to make it useful in such applications, and how origami is being used in education as a hands-on way to teach math.

  • s02e10: Martin Mulvihill: Safer Made: Chemistry Even New Parents Will Love
    Have you ever wondered what is in the toy that your baby just put in their mouth? Or about what goes into your hair conditioner and what happens when it gets washed down the drain? Chemicals, both natural and synthetic, are the building blocks of everything that you interact with every day. At Safer Made we support companies that create chemicals and materials that make our consumer products healthier for people and the natural world. This means creating alternatives to harmful chemicals and thinking about product design, from manufacturing through the end of a product’s useful life. In today’s marketplace, consumers are demanding safer and more sustainable products and this translates into a multi-billion opportunity for safer chemistry and product innovation. I will highlight current innovation trends in safer chemistry that are reshaping the way that packaging, textile and apparel, building materials, and formulated products are made. At Safer Made we believe that everyone plays a role in shaping the future of chemistry and this talk will share ways that you can get involved in supporting the creation of safer and more sustainable products.

  • s02e09: Ernest J. Moniz: Accelerating the Clean Energy Transformation
    The key outcomes of the Paris COP21 meeting in 2015 included: first, both an acknowledgement that global warming must be held below two degrees Celsius and national commitments to start down the road of deep cuts in greenhouse gas emissions; second, a multinational recognition that clean energy technology innovation is at the center of solutions to the climate challenge with associated commitments to double their innovation R and D budgets. Today, a consensus is emerging that we are collectively well behind any semblance of a successful trajectory to those ends. We must dramatically accelerate the clean energy transformation to a deeply decarbonized energy economy. This calls for a significantly expanded and refocused innovation agenda across multiple sectors of the economy – not just the electricity sector. The innovation pathway to a deeply decarbonized energy economy will be addressed.

  • s02e07: Paul Dawson: Double-Dipping and Other Food Peculiarities
    Have you ever eaten food after it has been dropped on the floor or double-dipped a chip? What about the cleanliness of restaurant menus or how sanitary it is to play beer pong. Paul Dawson will talk about what the research says on these and other topics related to the bacterial transfer on and around food. We’ll look at the ways bacteria live and move around the surfaces where we eat, drink and celebrate. Ice, lemon slices, sharing food, and even blowing out birthday candles will be placed under the microscope for close examination. So if you are still wondering who was correct, George Costanza (the infamous double-dipper from Seinfeld) or Timmy (the dip protestor), then come out on September 12th to hear some trivia and find the answer to these and other questions about food and bacteria.

  • s02e06: Katalin Gothard: The Magic of Emotional Touch
    Touch is essential for communicating our emotions. Indeed our earliest socio-emotional experience may be the protective embrace of a parent. Humans and non-human primates use touch to build and maintain bonds throughout life, yet little is known about how the brain extracts the emotional content of social touch. This talk will focus on the role of the amygdala, the emotional hub of the brain, in processing touch and in extracting the positive or negative valence of touch stimuli. Dr. Gothard will explain how neuroscientists explore questions related to touch and emotion, emphasizing the value and the benefits of gaining new, significant knowledge in this area of research.

  • s02e05: Anthony James: La Zanzara Vitruviana: Synthetic Biology and Malaria
    New technologies hold great promise for sustainable control of malaria parasite transmission by mosquitoes. The science of these technologies has advanced so quickly that the public understanding of their benefits and risks lags far behind. The challenge is to develop these new disease control methods while at the same time recruiting public support for the efforts.
