The Biological Basis of Obesity @ TORONTO: Medical Sciences Macleod Auditorium
Jan 15 @ 2:00 pm – 3:30 pm

Leptin and the Biological Basis of Obesity

Dr. Jeffrey Friedman

The discovery of leptin has led to the elucidation of a robust physiologic system that maintains fat stores at a relatively constant level. Leptin is a peptide hormone secreted by adipose tissue. This hormone circulates in blood and acts on the hypothalamus to regulate food intake and energy expenditure. When fat mass falls, plasma leptin levels fall stimulating appetite and suppressing energy expenditure until fat mass is restored. When fat mass increases, leptin levels increase, suppressing appetite until weight is lost. By such a mechanism total energy stores are stably maintained within a relatively narrow range.

In this talk, Dr. Jeffrey Friedman, a Professor at The Rockefeller University, and an Investigator for the Howard Hughes Medical Institute will discuss his discovery of the leptin hormone and how recessive mutation in the leptin gene is linked to obesity, infertility, diabetes and other immune abnormalities. He will also explore the several avenues by which leptin can be used to treat or correct an increasing number of human conditions.

Dr. Jeffrey Friedman is a physician scientist studying the genetic mechanisms that regulate body weight. His research on various aspects of obesity received national attention in late 1994, when it was announced that he and his colleagues had isolated the mouse ob gene and its human homologue.   Since then, Dr. Friedman has received countless honours and awards for his contribution to science, including his most recent Harrington Prize for Innovation in Medicine in 2016.

This talk is presented in partnership with the Gairdner Foundation.

RCIScience at Lunch!

The Food from Thought project

Dr. Evan Fraser

As the world’s population continues to grow, stories of food poverty and barriers to access persist.   This is not because we are undergoing a food shortage.  On the contrary, despite exponential rises in population over the past 25 years, production has historically always surpassed demand.  The unfortunate truth is that one third of the world’s food does not find its way to the table.  In the city of Vancouver alone, 80, 000 potatoes, 30,000 eggs and 70,000 cups of milk are thrown away each day.  It is this level of waste, along with the severe inequality that accompanies it, that creates an increased demand which threatens both local and global food security.  To meet this demand, food is often produced in varieties and quantities that are vastly different than what the world’s population needs.

Join RCIScience and Evan on Friday, January 20th at the First Canadian Place for a special look at factors like food waste, climate change, extreme weather events, and policy influence food security in Canada and globally.

Evan did degrees in forestry, anthropology and agriculture at the University of British Columbia and the University of Toronto. After graduating, he worked in a policy institute with the Hon. Dr. Lloyd Axworthy, and began his academic career in 2003 in the UK where he worked on farming and climate change at the University of Leeds. He is the author of over 75 scientific papers or book chapters on these topics, has written for the Guardian.com, CNN.com, ForeignAffairs.com, the Walrus, the Globe and Mail, the Toronto Star and the Ottawa Citizen, and has two popular non-fiction books about food and food security including Empires of Food: Feast, Famine and the Rise and Fall of Civilizations that was shortlisted for the James Beard Food Literature Award in 2010. In late 2014, he self-published a graphic novel called #foodcrisis that depicts a global food crisis hitting North America in the 2020s as a way of reaching 18-24 year-olds. His web video series on “feeding nine billion” has been watched over 280,000 times and used in classrooms around the world. Currently, Evan is Director of the Food Institute, a professor of Geography in the Department of Geography at the University of Guelph, where he holds the Canada Research Chair in Global Food Security. He is also an associate of the Guelph Food Institute, a Fellow of the Pierre Elliot Trudeau Foundation, a Fellow of the Royal Canadian Geography Society, and a Member of the Royal Society of Canada’s college of new scholars.

Dr. Richard Zemel @ TORONTO: Medical Sciences Macleod Auditorium
Jan 22 @ 2:00 pm – 3:30 pm

Dr. Richard Zemel

Interpreting the World with Machines: How information systems & statistical inference influence decisions

Information systems are becoming increasingly reliant on statistical inference and learning to render all sorts of decisions, including the issuing of bank loans, the targeting of advertising, and the provision of health care. This growing use of automated decision-making has sparked heated debate among philosophers, policy-makers, and lawyers, with critics voicing concerns with bias and discrimination.  Bias against some specific groups may be ameliorated by attempting to make the automated decision-maker blind to some attributes, but this is difficult, as many attributes may be correlated with the particular one.  The basic aim then is to make fair decisions, i.e., ones that are not unduly biased for or against specific subgroups in the population.  In this talk, Dr. Zemel will discuss social implications of this problem, and work that he has done on it as well as that by other groups.

Richard Zemel is a Professor of Computer Science at the University of Toronto.  Prior to that he was on the faculty at the University of Arizona in Computer Science and Psychology, and a Postdoctoral Fellow at the Salk Institute and at CMU. He received the B.Sc. in History & Science from Harvard, and a Ph.D. in Computer Science from the University of Toronto. His awards and honors include a Young Investigator Award from the ONR, a US Presidential Scholar award, and seven Dean’s Excellence Awards. He is a Fellow of the Canadian Institute for Advanced Research, an NVIDIA Pioneer of AI, and a member of the NIPS Advisory Board. His research interests include topics in machine learning, computer vision and neural coding.

Where Captain Nemo Got It Right, and Wrong – Life in the Deep Earth

From Jules Verne’s Captain Nemo, to Astronaut Mark Watney stranded on Mars, we remain fascinated by the theme of Exploration. Fact can be stranger than fiction however as we discover that even here on Earth, there are parts of the planet we have only begun to probe for new habitable domains and microbial ecosystems.

Today we will journey with explorers past, present and future as we descend into some of the places on Earth where life ekes out an existence far from the energy of sunlight. We will discuss microorganisms that draw their energy for life not from the sun but from the power of chemistry in the deep dark places of the Earth – in subsurface habitats ranging from the black smoker vents of the ocean’s hydrothermal fields, to deep fracture waters bubbling up 3 km below the surface of northern Canada and in the gold mines of South Africa.

How did they get so deep? What do they eat? How old are they? Some of the answers will make Mark Watney wish he had looked under a few rocks.

Dr. Barbara Sherwood Lollar, C.C. FRSC is a University Professor in Earth Sciences at the University of Toronto. She is Research Chair in Isotopes of the Earth and Environment, Director of the Stable Isotope Laboratory, and Past-President of the Geochemical Society. In 2015 she was named a Fellow of the American Geophysical Union. Sherwood Lollar has published extensively in research on stable isotope geochemistry and hydrogeology, the fate of carbon-bearing fluids and gases such as CO2, CH4 and H2 in ancient fracture waters in the Earth’s crust, and the role of deep subsurface microbial populations in carbon cycling. She has been a recipient of many academic awards (including the NGWA Darcy Lecturer, Steacie, Killam and NSERC Accelerator Awards) and most recently the 2012 Eni Award for Protection of the Environment 2012 Geological Society of America Geomicrobiology and Geobiology Prize, and NSERC Polanyi Research Award. Sherwood Lollar was selected in 2000 by Time Magazine Canada for their feature on ”Leaders for the 21st Century” and by Canadian Geographic in 2013 for their list of Ten Canadians “Changing the World” along with and Astronaut Chris Hadfield.

Wolverines: How did the secretive and solitary wolverine of the north acquire its reputation as a dangerous and ruthless killer? @ TORONTO: Medical Sciences Macleod Auditorium
Jan 29 @ 2:00 pm – 3:30 pm

 Dr. Justina Ray

How did the secretive and solitary wolverine of the north acquire its reputation as a dangerous and ruthless killer?

Few people have laid their eyes on a wolverine, an elusive creature that dwells in the farthest reaches of the world’s northern hemisphere and emblem of Canadian northern wilderness. This talk will provide a behind-the-scenes look at a decade of research in Ontario’s Far North addressing questions about this animal that range from the very basic (is there a breeding population in the province and where does it occur?) to complex issues that will be vital to the future survival of this animal (is natural resource development compatible with wolverines?).

Dr. Ray’s talk will be a behind-the-scenes look at a decade of research and policy engagement in Ontario. It would not only detail some of the scientific work and discoveries (starting from essentially no knowledge in the province), to how we have applied the best available information to real-world management and conservation decisions, including working with the trapper community.

Dr. Justina Ray has been President and Senior Scientist of Wildlife Conservation Society Canada since its incorporation in 2004. In addition to overseeing the operations of WCS Canada, Justina is involved in research and policy activities associated with land use planning and large mammal conservation in northern Canadian landscapes. She has been appointed to numerous government advisory panels related to policy development for species at risk and land use planning in Ontario and Canada and is Adjunct Professor at the University of Toronto (Faculty of Forestry) and Trent University (Biology Department).

Edible Nanostructures – The Pleasures of Chocolate @ MISSISSAUGA: Central Library
Feb 2 @ 7:00 pm – 8:30 pm

Edible Nanostructures & The Pleasures of Chocolate

Dr. Alejandro Marangoni

Dr. Alejandro Marangoni, University of Guelph

Butter and chocolate – two very pleasurable foods – taste the way they do because of their underlying fat crystal networks. In this talk we discuss cocoa butter, the structuring material in chocolate and confections, from solid-state structure and polymorphism to melting behavior and mechanical strength.  The reason for a tempering chocolate while mixing will become clear upon review of the effects of shear on the crystallization behavior of cocoa butter.  Recent advances on our understanding of how oil migrates through chocolate and causes blooming and chocolate softening will also be discussed.  

You will never look at chocolate in the same way after this talk.

Alejandro G. Marangoni, Ph.D., FAOCS, FRSC

3 recipients of grants from the Banting Research Foundation. The Banting Research Foundation’s mission is to invest in the early careers of researchers who demonstrate excellence and creativity in health and biomedical sciences. We are delighted to have this new partner to showcase excellence in early career researchers.

Dr. Michael Suits

A wide variety of microorganisms in the mouth are embedded in biofilms that contribute to periodontal diseases such as gum disease and tooth decay. To understand the contribution of a consortium of periodontal pathogens to biofilm formation and dental diseases, Dr Suits’ research group will clone, produce and isolate ~40-50 proteins selected using a bioinformatics-based approach with the aim of characterizing novel factors that contribute to biofilm formation and immune evasion.

 

 

 

Dr. Kaitlyn McLachlan

Individuals with fetal alcohol spectrum disorder (FASD) are overrepresented in the criminal justice system. There is an urgent need to identify neurobiomarkers of FASD and individuals at risk in order to reduce recidivism and the resulting high social, health, and economic costs. Novel use of neurotechnologies, including portable eye movement control tracking and EEG, may offer a window into the brain and aid in the identification of patterns of deficits in offenders with FASD.

 

 

 

Dr. Noam Miller
Animals that live in groups, including humans, have many advantages, including enhanced safety from predators and the possibility of taking advantage of social information. I will present an experiment designed to explore which of these two motivations for grouping drives cohesion in zebrafish schools. This research highlights that fish cognition is more complex than we often assume.

How Will We Eat on Mars? An Update on Life Support Research at the University of Guelph

Presented in partnership with the Mississauga Centre of the RASC

Dr. Michael Dixon

Dr. Michael Dixon, University of Guelph

If humans hope to ever get to Mars or farther, we will need to be able to grow food in space. The space travel environment produces unique challenges to growing food, including microgravity, limited water, artificial light sources and many more. Research at the Controlled Environment Systems Research Facility at the University of Guelph is showing us how to grow food in space and, in the process, is developing beneficial technologies for earth-bound farming.

 

Dr. Mike Dixon is the Director of the Controlled Environment Systems Research Facility and program, and Chair of the Environmental Biology Department, University of Guelph.  Dr. Dixon joined the University in 1985 as an NSERC fellow after earning his PhD from Edinburgh University in Scotland and is now a full professor.

Off campus he is the Technology Exchange Coordinator for the International Advanced Life Support Working Group (IALSWG) which is a strategic planning group offering information and personnel exchange between international space agencies such as NASA, CSA, ESA, RSA and JAXA (Japan).  He also is Chair of the Space Exploration Advisory Committee of the Canadian Space Agency (CSA) and is a member of the Life Sciences and Technical Committee within the American Institute of Aeronautics and Astronautics.

As project leader for the Canadian research team investigating the contributions of plants to life support in space, Dr. Dixon formed the Space and Advanced Life Support Agriculture (SALSA) program at the University of Guelph.  This program currently represents Canada’s prime contribution to the International Space program objectives in Life Support.

Dr. Dixon is also the project leader for the research team at Guelph investigating the biofiltration of indoor air as a method of alleviating what is commonly known as “sick building syndrome”.

Inch by inch, row by row, here’s some botanical information to help your garden grow

Dr. Dawn Bazely, Professor of Biology, York University

Dr. Dawn Bazely

Dr. Dawn Bazely, York University

The Nobel prizewinner, Albert Szent-Györgi, reminded us that photosynthesis is “what drives life”, and “is a little current, kept up by the sunshine”. Every plant can take in carbon dioxide and water, and make simple sugars, while giving off oxygen. We will discuss some botany basics to enhance your appreciation of flowers, fungi, seaweed and bacteria, and this information will help you to plan your garden better. Dawn’s husband grew okra, ladies’ fingers, in their Toronto garden in 2016.

Dawn is a professor of Biology in the Faculty of Science at York University in Toronto, where she has taught since 1990. She was Director of IRIS, the university-wide Institute for Research and Innovation in Sustainability (2006-11 and 2012-14). At IRIS, Dawn’s mission was to develop, lead and support interdisciplinary research on diverse fronts. The Globe and Mail’s 2014 Canadian University Report singled her out as York University’s HotShot Professor. Dawn trained as an ecologist in the field of plant-herbivore interactions, and has carried out extensive field research in grasslands and forests, from temperate to Arctic regions. She holds a B.Sc. (Biogeography and Environmental Studies) and M.Sc. (Botany) from the University of Toronto. Her D.Phil. in Zoology, from Oxford University’s Edward Grey Institute in Field Ornithology, looked at sheep grazing behaviour. She is a grass biologist who urges people to think about digging up their lawns!
