A monthly program designed for students in kindergarten through 12th grade and their parents to learn about exciting ideas and developments presented by professors and prominent experts in many scientific fields presented at Central Middle School. All programs are always free and no registration is required. The main presentation begins at 7:00 p.m. and is generally followed by a "Teen Roundtable" where students can participate in an in-depth discussion and question/answer session with the speaker. Programs are recorded for playback on ED's TV and a number of programs may be viewed online.
2016-2017 School Year – Welcome to the 25th Season!
Like food and shelter, clothing is an important part of everyday life for most people. It is so common that we often take it for granted. Yet, clothing is the first barrier between our human bodies and the outside world. Since the very earliest forms of clothing, it has provided essential functions like thermal insulation and protection from the sun. It has also communicated our status and identity. More advanced clothing forms need to cover additional functions which is done by resorting to wearable technology. This technology addresses the ability for clothing to understand the context and much more complex needs of the wearer and respond appropriately. Computer science and robotics are playing a critical role in clothing design. Dr. Dunne talks about the roots of clothing functionality as well as the cutting edge of how future clothing might look, function, and feel.

Dr. James Luby, University of Minnesota Department of Horticultural Science
Apple breeding at the University of Minnesota has been ongoing since 1908 and has produced 28 varieties including Minnesota favorites such as Honeycrisp and Haralson. Apple breeding involves both the science of genetics and the craft of identifying fruit with desirable properties such as taste, flavor, color and texture. This presentation covered how breeders develop new apple varieties that are adapted to our region and provide delightful fruit for apple consumers and apple processors.

"Symmetry, Invariants, Puzzles, and Cancer"
Dr. Peter Olver, University of Minnesota School of Mathematics
Basic problems in image processing include recognizing when two objects are the same and classifying what are the similarities, or symmetries. But to solve the problems, one must understand what about the objects that are not alike, the invariants. This talk introduced the basics of groups, their symmetries and their invariants as illustrated by simple examples and pictures... and was followed by recent applications to automated jigsaw puzzle assembly and cancer detection.

"Comets: The Treasure Chest in the Cosmic Attic"
Dr. Charles Woodward, University of Minnesota Institute for Astrophysics
Solar system formation is a process that combines and transforms ices, organics and dust grains into a variety of objects, and ultimately into planets. Comets, formed at the beginning of this process, contain these materials as well as material transported from hotter regions closer to the sun. Do these materials of the comet contain clues as to what happens in planet formation? The program explored this idea, talking about the Rosetta/Philae comet-landing mission and glimpsed at the astrobiological importance of these cosmic wanderers!
Dr. Woodward mentioned several books for further insights:
T Rex and the Crater of Doom, 1977 Walter Alvarez (Princeton U. Press)
Five Billion Years of Solitude, 2013 Lee Billings, (Current / Penguin)
Dr. Woodward also spoke to young scientists on December 1, 2009 about "Water on the Moon?: NASA L-CROSS Mission". Watch a short video excerpt of Dr. Woodward talking about education and training for careers in science.
Dr. Terry Jones, University of Minnesota Department of Physics and Astronomy
Albert Einstein is famous for his Theory of Relativity, but many people do not know that he actually developed two theories. The first is called the Special Theory of Relativity, which explains what happens to objects moving at speeds close to the speed of light relative to each other, but does not include the effects of gravity. Einstein later developed his General Theory of Relativity which includes gravity and led to our current understanding of the Universe as a whole. Dr. Jones focused on the Special Theory of Relativity, which is surprisingly accessible to students, and forces us to think differently about time and space. He also covered the General Theory of Relativity and how both profoundly important theories are used in nearly all of our current technologies. And he discussed Black Holes in Outer Space.
October 5, 2015 – "A New Era of Discovery: In Search of Earth-Like Planets"
Dr. Steven Kawaler, Professor of Physics and Astronomy at the University of Iowa
The past few years have seen some amazing discoveries of planets orbiting other stars -- solar systems that are in some cases very different from our own. To make these discoveries possible, astronomers have developed ways to detect these planets despite the tremendous glare from the stars that they orbit. In this presentation we will look at examples of how to find planets around other stars, and sample the variety of planetary systems that populate our galaxy -- concentrating on results from NASA's Kepler Spacecraft. The next decade will see new discoveries with spacecraft in the planning stage that will probe the atmospheres of nearby planets and, perhaps, find evidence for life on one of these extrasolar planets.
February 2, 2015 – "The Amazing World of Modern Optics"
Dr. James Leger is a Professor of Electrical Engineering at the University of Minnesota where his research group is studying a wide variety of optical techniques, including laser mode control and beam shaping techniques, spectral and coherent laser beam combining, optical metrology, solar energy optics, design of nonclassical imaging systems and microoptical engineering. Holograms were demonstrated during the Teen Roundtable.
November 11, 2014 – "Emerging Infectious Diseases: Looking Into a Crystal Ball"
Dr. Michael T. Osterholm has appeared several times at Young Scientist Roundtable. He is Director of the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota and worked previously as the state epidemiologist at the Minnesota Department of Health. His appointments include the National Science Advisory Board on Biosecurity and the World Economic Forum Working group on Pandemics. Dr. Osterholm had been traveling, meeting and speaking extensively about the Ebola outbreak in the Fall of 2014. He spoke to young scientists to discuss his work on this important disease crisis as it was unfolding, along with other infectious diseases of concern around the world.
The program was first played back on ED's TV on Thursday-Sunday January 22-25, 2015.
October 6, 2014 – "Air Quality Engineering to Combat Air Pollutants"
Dr. Julian Marshall, Associate Professor of Civil Engineering at the University of Minnesota. According to the World Health Organization, urban air pollution is one of the top ten cases of death in high-income countries. How we can reduce those health effects and improve public health was a focus of this presentation. Dr. Marshall discussed pollutants from various types of fuels (such as fossil, biofuel), and computer modeling to reduce exposure to them. The goal was to understand whether biofuels are better for human health and the environment than the fossil fuels they replace. The discussion covered a range of scenarios from an urban U.S. locality to a rural village in India or Uganda.
March 2, 2015 – "Leukemia: The Search for a Cure"
Young Scientist Roundtable was pleased to announce the return of Dr. John Wagner, a Professor of Pediatrics and Executive Director of the Pediatric Blood and Marrow Transplantation Center at the University of Minnesota.
He also spoke to young scientists about "Biological Revolution: Stem Cells" on March 11, 2009.
