When it Rains, it Pours!
Featuring Clyde Goulden, Academy of Natural Sciences of Drexel University

From November 30th to December 11th, world leaders will convene in a suburb of Paris to discuss climate action. The 21st United Nations Conference on climate change, called COP21, is sure to draw equal parts controversy and praise. What role do scientists play in all of this? Dr. Clyde Goulden, who researches rain changes, will present an overview of his research on global rainfall and his reactions to the talks.

Going Wild in the City: The Evolution of Attitudes Toward Urban Evolution
Featuring Karen Snetselaar, Professor of Biology at Saint Joseph’s University

Several hundred years ago the wilderness was a frightening place where people might be banished to die alone, with no human support. The romantic idea of wilderness as a place where we go to get away from the cares of civilization is more recent and still prevails today. In neither of these very different views of wilderness is there a permanent place for people! And a conviction that wilderness (or true nature) can exist only without human interference has greatly influenced scientific investigations as well as vacation planning. Until quite recently, human-dominated ecosystems weren’t considered proper venues for mainstream ecology.

One can argue that serious challenges to this narrow view really began with the environmental movement of the 1960’s and 70’s, and it has become increasingly difficult to claim that there are places on the planet not impacted by human activity. Urban ecology and related fields are now much more widely accepted as appropriate and important scientific disciplines. After a discussion of how we finally got here, we’ll consider how this is changing our view of urban environments and leading to increased respect for the wild things found there.

Cancer Science: The Quest for a Cure
Featuring Pat Morin, Senior Director of Scientific Review and Grants Administration at the American Association of Cancer Research

Cancer.  It’s only one word, yet we now know it represents more than 200 diseases.  In 1907, it was a death sentence.  In that year, 11 physicians and scientists came up with a novel idea to collaborate to prevent and cure cancer.  They established the American Association for Cancer Research (AACR), which is headquartered right here in Philadelphia.

Today, we are still on a quest for that cure.  So much progress has occurred, yet nearly 600,000 Americans still die from cancer each year.  Join this month’s Science on Tap to learn about cancer science history, the trials and tribulations of scientific promise and failure.  And hear about today’s latest advancements in personalized medicine and immunotherapy.  There has never been a more exciting time in cancer research and treatment.  Pat Morin, PhD, of the AACR will explain, in simple terms, the current state of cancer research, and will highlight the latest and greatest in our quest to identify cures for this insidious disease.

The History of the Chemical Elements for (Big) Kids
Featuring Adrian Dingle, chemistry educator, author, and 2015 Société de Chimie Industrielle Fellow at the Chemical Heritage Foundation

The National Science Education Standards says that “The natural and designed world is complex; it is too large and complicated to investigate and comprehend all at once. Scientists and students learn to define small portions for the convenience of investigation… referred to as ‘systems’.” We know that the periodic table is one such system, but the methods for teaching it range from rote memorization to endless rounds of flashcards to chanting the elements call-and-response style. School is out, so what better time to think of a fun way to teach this concept? Join CHF Fellow, Adrian Dingle, as he talks about his most recent project, a children’s book about the history of the chemical elements. Learn a few fascinating facts behind the discovery of some of the elements, all delivered from an easy to follow kids perspective – oh, and with beer, too!

Join the DarkSide: Dark Matter Matters
Featuring Christina Love, Assistant Teaching Professor in the Department of Physics at Drexel University

Dark matter makes up over 80% of all the matter in the universe. We don’t know what it is. We can indirectly see dark matter by the gravity that it produces, but we have yet to directly detect it. There are three ways that researchers are currently looking for dark matter: particle detectors, particle accelerators, and excess particles.

Why We (and Weebles) Wobble but Don’t Fall Down
Featuring Tonia Hsieh, Assistant Professor of Biology at Temple University.

As you traverse the hazard-filled streets of Philadelphia on a daily basis, have you ever had to think about how you will step on and off a sidewalk, dexterously avoid a pothole, or simply stay upright and not fall down while walking? Though it might seem automatic to you, it turns out that moving through our natural and built environments is no easy feat. Movement is something that all animals do, and often in amazingly acrobatic ways. Ask a robot to do it, however, and it will often struggle and fall over the simplest obstacles. This talk will reveal some mysteries of animal locomotion that allow us to move through the world with grace and composure (most of the time). It will also show how integrating biology into robotics is enabling ever deeper insights into both biology and robotic design.

The Lost World of Plant Monsters: Animal-Plants, Stone-Plants, and Other Categorical Challenges
Featuring Lynnette Regouby, Mellon Post-Doctoral Fellow at the American Philosophical Society Museum.

Stone-Plants. Animal-Plants. Sensitive Plants. Eighteenth-century natural history was populated with categories that we no longer recognize but that at the time presented serious challenges to classification. This talk revisits a world of plant monsters, whose ability to walk, to feed, or to feel, breeched the boundaries between animal and vegetable kingdoms and helped to revise what it means to be a plant, a human, or something in between.

Shots for Spots and Want-It-Nots: Measles, Measles Vaccine, and Refusers
Featuring Karie Youngdahl, Director of the History of Vaccines project.

The recent measles outbreak stemming from exposures at Disneyland has focused attention on this disease that was eliminated from the United States in 2000. Karie Youngdahl, director of the History of Vaccines project, will put the current outbreak in historical context by looking at the epidemiology of measles over time and attempts at immunizing for measles from the mid-1700s. She will also discuss resistance to vaccination and the ways that arguments against vaccine have been made by anti-vaccinators from Edward Jenner’s time to now.

Guano Happens: A Illustrated History of Fertilizers in America.
Featuring Timothy Johnson, the Allington Dissertation Fellow at the Chemical Heritage Foundation for 2014-15 and a Ph.D. candidate in history at the University of Georgia.

In late summer 2014, some 400,000 residents of Toledo, Ohio lost access to tap water because of a massive bloom of toxic cyanobacteria in Lake Erie.  Every summer, similar events occur in watersheds that drain regions where soils are saturated with chemical fertilizers on farms and lawns.  If humans are responsible for this annual toxic tide, why has it been so hard to stop it?  In this talk, Timothy Johnson will discuss the environmental history of chemical fertilizers in the United States, exploring topics as diverse as guano islands, explosives production, and comic books to show how fertilizers became an indispensable tool for farmers, in spite of the considerable costs they have incurred.

The Floor is Lava (Literally): The Do’s and Don’ts of Volcanology
Featuring Loÿc Vanderkluysen, Ph.D., Assistant Professor, Department of Biodiversity, Earth & Environmental Science, Drexel University

Every year, an average of 60 volcanoes erupt worldwide; approximately 15 of these eruptions have the potential to disrupt air traffic and cause widespread destruction. The practical consequences of these damaging effects made front-page news in 2010, following the eruptions of Eyjafjallajökull volcano in Iceland (which caused extensive air traffic disruptions and flight cancellations), and Merapi volcano in Indonesia (during which 353 people were killed, and 350,000 were displaced). These events highlighted the need for novel and improved real-time volcano monitoring tools. In this presentation, Dr Vanderkluysen will talk about current eruptions in Hawaii and elsewhere across the globe, recent technological developments in volcano monitoring, and volcanic surveillance in the United States.
