The amazing diversity of life is the result of billions of years of evolution. But how did evolution itself begin? I will describe how efforts to design and build very simple living cells are testing our assumptions about the nature of life, generating ideas about how life emerged from the chemistry of the early Earth, and even offering clues as to how modern life evolved from its earliest ancestors.

Global energy consumption is conservatively projected to expand two-fold by 2050. A survey of our renewable options reveals the Sun as the only viable non-carbon based energy source. Currently, silicon-based photovoltaics (PV) dominate the market. They are a practical and mature technology, but expanding the solar energy market to meet our needs will require a substantial change in technology. This presentation will survey recent advances in PV technology and ‘shed some light’ on the current research directed at making materials that can supplement our current use of silicon cells.
The first European settlement of Toronto was simply a continuation of patterns that had been in place for thousands of years. The Aboriginal occupants of the encampments and semi-permanent villages that lined the former water courses in the City left no written record of their lives. Their legacy consists of the oral histories and traditions passed on to descendants and the surviving traces of those settlements. This talk will summarize this rich archaeological record and discuss how the City of Toronto is ensuring its conservation.

Climate change affects different parts of Canada in different ways. Predictions indicate that Southern Ontario will experience more droughts and heavy rainfalls that can greatly affect ecosystems and especially plants. In Atlantic Canada, sea level rise, continuous coastal erosion and more frequent storm surges threaten the fragile coastal ecosystem. I will describe some of the projects that I am involved with to examine the potential impacts of climate change on the human condition in Ontario and Atlantic Canada, and the actions taken to try to adapt and improve resilience of communities and ecosystems.
The impact hazard from small asteroids is uncertain because of many poorly understood factors. These include how asteroids vapourize in the atmosphere together with the associated impact effects at the ground. The Chelyabinsk event gave scientists their first detailed instrumental data on a well observed, damage-producing airburst. I will describe what we have learned about the Chelyabinsk airburst in the year since it occurred and what it may tell us about future impacts at the Earth.

Social insects like ants, bees and some wasps live in large colonies composed of many sterile workers and a few reproductive individuals. The division of labour between workers and queens is believed to be at the heart of the dominance of social insects. But how do social insects evolve and adapt when most members of their societies are sterile workers? I will present our laboratory’s recent progress on understanding the relationship between genes, worker behaviour, and evolution in the honey bee, Apis mellifera.
The shrinking Arctic sea ice cover is often taken as one of the most prominent indicators of recent climate change, andThe shrinking Arctic sea ice cover is often taken as one of the most prominent indicators of recent climate change, and its early, complete disappearance seems almost inevitable in the public debate, spawning speculations about the opening of northern shipping routes and resource exploration, as well as about the extinction of polar bears and the collapse of Arctic food-webs. However, little is actually understood about the recent rapid sea ice changes in the
Arctic, and climate models continue to predict sea ice changes with little skill. The presentation will provide a status of observed sea ice changes in the Arctic and Antarctic, and will discuss some of the uncertainties related to changes of the sea ice mass balance. I will then focus on results of our own field and remote sensing research with regard to Arctic sea ice, particularly results from airborne and snowmobile-based ice thickness surveying. Results show large regional sea ice variability in the Canadian Arctic which represent different environmental conditions and prevents easy, general predictions of future ice conditions.
The incredibly small bits of matter we call neutrinos may hold the secret to why antimatter is so rare, how mighty stars explode as supernovae, what the universe was like just seconds after the big bang, and even the inner workings of our own planet. In Neutrino Hunters, I will take you on a thrilling journey into the shadowy world of neutrinos and the colorful lives of scientists chasing these elusive particles, recounting a captivating saga of scientific discovery and celebrating a glorious human quest. Hear what the next decade of neutrino hunting may hold in store.

Science and art often have a perceived divide in contemporary culture, yet historically their roots stem from similar manifestations of creativity and aesthetics, in exploring, responding to and explaining Nature. This panel presentation brings together scientists, artists and those with a foot in each of the ‘two cultures’ to discuss their interdisciplinary practices, and encourage novel ways to understand the world around us.

Microscopes have been serving scientists for more than four hundred years and provided a possibility to glimpse into the lives of cells and minute living organisms. Modern microscopes utilize lasers with very short pulses to help visualize cells without labeling and in their natural environment. We use advance microscopy to study the structural dynamics of cells in plant and animal tissue, and how their behaviour is affected by diseases including cancer. I will guide you into the inner parts of a moving cell and discuss how cells contract and react to changes in the environment.
