Photosynthetic solar energy conversion occurs on an immense scale across the earth, influencing our biosphere
from climate to oceanic food webs. These are amazing solar cells! Fronds in kelp forests, crustose coralline algae and
purple bacteria have shown interesting properties relevant these energy transfer phenomena. Underpinning these examples are some fascinating chemical physics, where experiments and theories reveal the mechanisms involved in the ultrafast energy transfer processes of light harvesting. This talk will introduce the incredible physical processes that initiate photosynthesis in the first picoseconds after light is absorbed.

Viewing the genome as a collection of recipes rather than a catalogue of genes is fundamentally changing how we think about and treat genetic diseases such as cancers, spinal muscular atrophy and autism. The implications for you personally and for the sustainability of health care are shocking.

Exciting new genetics research is in the news almost daily. Companies promise (for a fee) to analyze your genome (but beware!). Despite the hype, the real discoveries are truly extraordinary and are transforming our understanding of normal biology, and how we manage and treat disease.

What happens in our brains that allows us to calculate and become mathematically fluent? As the brain develops, the structures and functions associated with calculation change dynamically. In this talk of interest to educators, parents and anyone who has ever felt “mathematically challenged”, we will explore how individual differences in competence and strategy-use affect the brain as we calculate.

Each year, billions of migratory organisms on our planet commute vast distances between their temperate breeding grounds and tropical overwintering habitats. I will share with you how we’ve uncovered some of these incredible, record-breaking migrations and, using an example of the iconic monarch butterfly, show why tracking individuals over the course of the annual cycle is fundamental for their successful conservation.
In the field, people can now record plant and animal sightings in real time with their smart phones. At the same time, emerging radio tracking technology known as “motus” (from the Latin for “motion”) is transforming bird migration research. Together, these open the door to new “citizen science” and exciting discoveries in both the academic and recreational realms, key to conserving birds and all wildlife.
Sir John Franklin’s third expedition, the most infamous European voyage to navigate a sea route through the Canadian Arctic, has captivated people in Canada and around the world for a century and a half. Explore recent archaeological research and what it tells us about the lives and deaths of these explorers has revealed about the lives and deaths these explorers. Join the voyage as we revisit the momentous finds that led to the discovery of Franklin’s long-lost ship Erebus.
Circadian rhythms are 24-hour biological rhythms that affect our health and behaviour, influencing many things, from the best time to take a test, to the timing of a heart attack or stroke, to the arrival of death itself. Recent discoveries about the mechanisms underlying circadian rhythms have implications on how we organize school, work, social, and medical schedules.
Thanks to NASA’s Mars Rovers, we know much more about our planetary neighbour than we did a decade ago. Controlled from Earth, experiments conducted by the Rover instruments reveal that Mars was once a more habitable place. A key instrument on all 4 Mars Rovers and also on the Rosetta mission lander, Philae, is the Canadian APXS experiment, a soda-can sized device that measures the composition of rocks and soils.

An afternoon of engaging hands-on activities geared towards children 6-12 years and their families, sharing the excitement of science, technology, engineering and math.
Volunteers running the activities will include post-secondary students who are eager to share their passion for science and can help answer your questions.
Doors open at 1:30 pm
Event ends at 3:30 pm
On average, we urban dwellers spend about 90% of our time indoors, and share the strong intuition that the physical features of the places we live and work in influence how we feel and act. Explore how the brain responds to variations in the physical features of our environments, and the effect this has on our appreciation for various types of spaces and our decisions to enter or exit it.
This presentation briefly sketches the evolution of urban form and transportation and then explores issues and options for evolving 21st Century cities into more sustainable, attractive “homes” for people and firms.
Hosted by Ryerson University.
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.
