Self-driving cars, for example, can be trained on simulated roads and highways before theyā€™re let loose on actual city streets. But scalability remains a challenge. If an autonomous system has to be specially trained for every possible scenario it might encounter, progress will be haltingly slow; there will be no way to take whatā€™s been learned from one scenario and scale it up so that the system can handle more general cases.</p> <p>In an ideal world, Shkurti says, a robot could learn similar to the way a human would.</p> <p>Take, for example,&nbsp;robots that help scientists collect data underwater ā€“ an effort Shkurti has been involved with for several years.&nbsp;A human diver ā€œhas to collect data manually, one data point at a time, one location at a time,ā€ Shkurti says. ā€œItā€™s&nbsp;painstaking work; itā€™s not scalable.ā€</p> <p>An autonomous robot, on the other hand, could take over the data collection process if itā€™s&nbsp;capable of maneuvering underwater and equipped with a camera and other sensors. ā€œIf the robot could understand what itā€™s doing ā€“ if it has a model of what the scientist thinks is important to pay attention to&nbsp;in a particular environment&nbsp;ā€“ then the robot could collect data on behalf of the scientist.ā€</p> <p>Such an approach has many benefits, according to Shkurti: Itā€™s much cheaper to deploy additional robots than to train more scientists;&nbsp;and it frees up the scientist to look after higher-level tasks. ā€œThe scientist can give the robot some hints as to where to collect the data ā€“ but then the robot can take care of the rest,ā€ he&nbsp;says.</p> <p>Shkurti, who&nbsp;did his undergraduate studies at ³Ō¹Ļ±¬ĮĻ before earning his PhD in computer science at McGill in computer science, was hired by ³Ō¹Ļ±¬ĮĻ in 2018.&nbsp;He recently received a&nbsp;Connaught New Researcher Award&nbsp;for a project titled ā€œRobotics and Machine Learning in the Wild: New Directions in Automated Environmental Monitoring.ā€</p> <p>Hey says that while everything about computer science fascinates him, the field of robotics holds special appeal.&nbsp;</p> <p>ā€œRobotics lets you play in different ā€˜playgrounds,ā€™ like control, perception, and machine learning,ā€ he says. ā€œIt allows you to examine these different fields, and I really valued that ā€“ and I still value it.ā€</p> <p>As for the lofty philosophical questions that sometimes crop up when people talk about advanced computer systems ā€“ such as&nbsp;whether machines could learn to&nbsp;ā€œthinkā€ ā€“ Shkurti prefers to stay focused on the science. Machines can reason, he says, and&nbsp;they can try to act optimally as they strive to achieve their goals.</p> <p>ā€œIf thatā€™s thinking, then theyā€™re doing it,ā€ he says. ā€œBut I donā€™t spend very much time worrying about ā€˜consciousness.ā€™ I have enough other things to worry about.ā€&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 15 Oct 2021 16:45:31 +0000 Christopher.Sorensen 170852 at Courage and sacrifice: A look back at ³Ō¹Ļ±¬ĮĻ during the First World War /news/courage-and-sacrifice-look-back-u-t-during-first-world-war <span class="field field--name-title field--type-string field--label-hidden">Courage and sacrifice: A look back at ³Ō¹Ļ±¬ĮĻ during the First World War</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/Postcards-1140-x-760.jpg?h=afdc3185&amp;itok=0GmXM_os 370w, /sites/default/files/styles/news_banner_740/public/Postcards-1140-x-760.jpg?h=afdc3185&amp;itok=7XsIpNb- 740w, /sites/default/files/styles/news_banner_1110/public/Postcards-1140-x-760.jpg?h=afdc3185&amp;itok=JoAqGmrN 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/Postcards-1140-x-760.jpg?h=afdc3185&amp;itok=0GmXM_os" alt="Postcards from France "> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>noreen.rasbach</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2018-11-09T11:26:41-05:00" title="Friday, November 9, 2018 - 11:26" class="datetime">Fri, 11/09/2018 - 11:26</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Postcards sent home from France during the First World War by Gerald Blake, ³Ō¹Ļ±¬ĮĻ alumnus and grandson of Edward Blake, former ³Ō¹Ļ±¬ĮĻ chancellor and premier of Ontario (Postcards from ³Ō¹Ļ±¬ĮĻ Archives; photo by Romi Levine)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/ginny-galt" hreflang="en">Ginny Galt</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/city-culture" hreflang="en">City &amp; Culture</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/u-t-archives" hreflang="en">³Ō¹Ļ±¬ĮĻ Archives</a></div> <div class="field__item"><a href="/news/tags/alumni" hreflang="en">Alumni</a></div> <div class="field__item"><a href="/news/tags/connaught" hreflang="en">Connaught</a></div> <div class="field__item"><a href="/news/tags/faculty-law" hreflang="en">Faculty of Law</a></div> <div class="field__item"><a href="/news/tags/faculty-medicine" hreflang="en">Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/first-world-war" hreflang="en">First World War</a></div> <div class="field__item"><a href="/news/tags/global" hreflang="en">Global</a></div> <div class="field__item"><a href="/news/tags/hart-house" hreflang="en">Hart House</a></div> <div class="field__item"><a href="/news/tags/remembrance-day" hreflang="en">Remembrance Day</a></div> <div class="field__item"><a href="/news/tags/university-college" hreflang="en">University College</a></div> <div class="field__item"><a href="/news/tags/victoria-college" hreflang="en">Victoria College</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>At the outset of the First World War in 1914, an unfinished theatre in the basement of Hart House was commandeered for trench warfare drills. The set ā€“ painted to depict a battered Belgian village ā€“provided the backdrop for rifle practice by students who had enlisted in the Canadian Officers' Training Corps. The set designer, Lieutenant <strong>Lawren Harris</strong>, would go on to become one of the famed landscape artists in Canadaā€™s Group of Seven.</p> <p>It was one of the more fascinating periods of the University of Toronto's storied history, as recounted in <em>The University of Toronto: A History</em> by author <strong>Martin L. Friedland</strong>, <a href="https://www.provost.utoronto.ca/awards-funding/university-professors/">University Professor </a>Emeritus in the Faculty of Law. In his chapter on the Great War,&nbsp;Friedland captures not only the heroics and sacrifices of those who saw active service, but also the ingenuity and enterprise of students and faculty who supported the war effort from home. By Nov. 11, 1918,ā€œthe long agony was over,ā€ Friedland writes, quoting from the ³Ō¹Ļ±¬ĮĻ's official Roll of Service.&nbsp;</p> <p>But there were profound and lasting effects. On the 100<sup>th</sup> anniversary of the end of the First World War, his account&nbsp;provides a compelling refresher:<img alt class="media-image attr__typeof__foaf:Image img__fid__9604 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/MacDowell-239-x-316.jpg" style="width: 239px; height: 316px; float: left; margin: 10px 30px;" typeof="foaf:Image"></p> <ul> <li>While no amount of training could prepare young ³Ō¹Ļ±¬ĮĻ recruits for the horrors they would face, there were incredible acts of courage. Major<strong> Thain MacDowell </strong>(pictured left, courtesy of ³Ō¹Ļ±¬ĮĻ Archives)&nbsp;won the Victoria Cross for his actions at Vimy Ridge, where, despite being separated from the rest of his unit, he and two other men took control of two German machine guns. They chased a fleeing gunner down a tunnel, only to encounter 77 more German soldiers.&nbsp;ā€œMacDowell convinced them they were surrounded by a larger force, and so brought about their surrender,ā€&nbsp;Friedland writes.</li> <li>Physicians put themselves in the line of fire to deliver new treatment methods to the ill and wounded. Surgeon <strong>Bruce Robertson</strong>, a ³Ō¹Ļ±¬ĮĻ medical graduate, took his modern blood transfusion knowledge to the front lines at a time when physicians from allied countries were still routinely replacing lost blood with saline solutions. Two influential articles by&nbsp;Robertson, published in the <em>British Medical Journal</em>, changed attitudes about the use of blood transfusions for saving lives, Friedland writes.</li> </ul> <h4><br> <a href="/news/heartbreaking-letters-triumphant-trophies-12-objects-tell-story-u-t-during-great-war">Read:&nbsp;From heartbreaking letters to triumphant trophies: 12 objects that tell the story of ³Ō¹Ļ±¬ĮĻ during the Great War</a><br> <br> <a href="/news/then-and-now-take-look-these-photos-first-world-war-campus">Then and now: Take a look at these photos of the First World War on campus</a><br> <br> <a href="/news/neither-upbeat-nor-sombre-u-t-alumnus-commissioned-compose-new-carillon-piece-mark-first-world">Neither upbeat nor sombre: ³Ō¹Ļ±¬ĮĻ alumnus commissioned to compose new carillon piece to mark First World War</a><br> <br> <a href="/news/where-and-when-attend-remembrance-day-events-across-u-t-s-three-campuses">Where and when to attend Remembrance Day events across ³Ō¹Ļ±¬ĮĻ's three campuses</a></h4> <p><img alt="Connaught labs" class="media-image attr__typeof__foaf:Image img__fid__9605 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/Connaught-750-x-500.jpg" style="width: 750px; height: 500px; margin: 10px;" typeof="foaf:Image"><br> <em>Crates containing serums made by Connaught Laboratories, created en masse to assist the war effort (photo courtesy of ³Ō¹Ļ±¬ĮĻ Archives)</em></p> <ul> <li> <p>Public health pioneer <strong>John FitzGerald</strong>, founder of Connaught Laboratories, overcame the ³Ō¹Ļ±¬ĮĻā€™s initial reluctance to become involved with a commercial venture and incorporated his development of antitoxins into the department of hygiene. <strong>Robert Falconer</strong>, ³Ō¹Ļ±¬ĮĻ president at the time, received $5,000 in support from the federal government ā€“ the first grant ever received by ³Ō¹Ļ±¬ĮĻ from the federal government for laboratory work. It went towards production of tetanus antitoxin, as well as smallpox and typhoid vaccines,&nbsp; and, according to the ³Ō¹Ļ±¬ĮĻ hygiene professors, reversed the trend of more Canadian men dying of disease than of wounds in France.</p> </li> <li> <p>On the home front, with so many of their male classmates and professors enlisting in the medical army corps or working in field hospitals, the number and proportion of women in the Faculty of Medicine increased considerably. At Victoria College, women outnumbered men by the end of the 1916 academic year and the number of women in junior faculty positions at the university had increased from 15 to 60 by the end of the war. Almost all of the students who remained on campus during the war years signed up for national service, taking on the work of men who had gone overseas. Classes ended a month earlier than usual so female students could plant, harvest and sell farm crops.</p> </li> <li> <p>Throughout, students became accustomed to unusual sights ā€“ a Sopwith Camel aircraft in front of University College, for instance. The campus had become a training ground for the British Royal Flying Corps and tent cities cropped up to accommodate the airmen. Canada did not have its own air force at the time, so Canadians and Americans had to join the British outfit if they wanted to fly. American novelist William Faulkner, who was 20 at the time, trained at ³Ō¹Ļ±¬ĮĻ, where some of the lectures were delivered by members of the engineering faculty.</p> </li> <li> <p>The Faculty of Engineering engaged in organized industrial research for the first time. Many professors also contributed directly to the war effort, using their expertise and lab equipment to test chemical explosives or the steel casings of shells. In 1918, the faculty of engineering obtained Canadaā€™s first wind tunnel, which allowed the testing of aircraft by simulating flight without risk to the pilot.</p> </li> <li> <p>Overseas, the casualties were horrendous.&nbsp;Friedland writes that about 10 per cent of the 6,000 ³Ō¹Ļ±¬ĮĻ people who went to war lost their lives and likely an equal number were wounded, gassed or captured. As the veterans returned to campus, ³Ō¹Ļ±¬ĮĻ psychology professor <strong>E.A. Bott</strong> developed rehabilitation methods to treat not only the physical wounds, but also the mental wounds. His colleagues in the engineering faculty became involved in the rehab efforts, training more than 300 women as occupational therapists. Surgeon Alexander Primrose, who helped form the Ontario Society for Occupational Therapists shortly after the war, wrote that the work of the therapists helped shorten the patientsā€™ recovery time.</p> </li> <li> <p>One hundred years ago at ³Ō¹Ļ±¬ĮĻ, on Nov. 11, ā€œthe buildings were closed, and for a day, all gave themselves up to common rejoicing,ā€ records the Roll of Service.</p> </li> </ul> <p>Read more about the First World War at ³Ō¹Ļ±¬ĮĻ:</p> <ul> <li><a href="https://magazine.utoronto.ca/campus/history/changed-by-war-nothing-lacking-but-the-roar-of-battle-alice-taylor/">How students trained in combat-like conditions in the basement of Hart House with a real trench and mural of a Belgian village painted by Lawren Harris</a>.&nbsp;</li> <li><a href="http://https://magazine.utoronto.ca/campus/history/changed-by-war-farmerettes-help-at-home-alice-taylor/">How ³Ō¹Ļ±¬ĮĻ women became ā€œfarmerettesā€ in the summer ā€“ helping out in the fields while male&nbsp;farmers were off at war</a>.&nbsp;&nbsp;</li> <li><a href="https://magazine.utoronto.ca/campus/history/changed-by-war-waging-war-on-infection-alice-taylor/">In 1914, 32 per cent of the British wounded contracted tetanus.

But why students choose self-harm over other coping behaviours remains a mystery, says lifespan development psychologist <strong>Chloe Hamza</strong>.&nbsp;</p> <p>Understanding and eventually disrupting this cycle of self-abuse, which increases later risk of suicidal behavior by two to four per cent among students, is the focus of an ambitious research project by the assistant professor in the department of applied psychology and human development at the Ontario Institute for Studies in Education.</p> <p>Her research is receiving support from the&nbsp;<a href="http://connaught.research.utoronto.ca/">Connaught New Researcher Award</a>.</p> <p>The annual awards are only provided to ³Ō¹Ļ±¬ĮĻ assistant professors within the first five years of a tenured-stream academic appointment to help them establish strong research programs. This year the Connaught Fund is awarding a total of $994,000 to 56 researchers across a range of disciplines. See below for a full list of recipients.</p> <p>ā€œCongratulations to this yearā€™s winners of the Connaught New Researcher Award on their well-deserved achievement,ā€ said Professor<strong> Vivek Goel</strong>, ³Ō¹Ļ±¬ĮĻā€™s vice-president of research and innovation.&nbsp;</p> <p>ā€œThis funding is designed to help some of the best up-and-coming ³Ō¹Ļ±¬ĮĻ researchers get their vital projects off the ground and position them to go after and secure external funding to continue and expand their research down the road.ā€</p> <p>Hamza (pictured below) just joined ³Ō¹Ļ±¬ĮĻ last July. She&nbsp;is over the moon about the funding ā€“&nbsp;her first research grant to do her own independent study on such a surprisingly understudied area of mental health.</p> <p><img alt="headshot of researcher" class="media-image attr__typeof__foaf:Image img__fid__4839 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/2017-06-01-resized-headshot-chloe.jpg" style="width: 350px; height: 475px; margin: 10px; float: left;" typeof="foaf:Image">ā€œItā€™s very exciting,ā€ she says about receiving the $35,000 in Connaught funding. ā€œI think this also underscores the universityā€™s recognition of the importance (and prioritization) of funding research that can serve to inform efforts to promote positive mental health and well-being among students on campus.ā€</p> <p>Non-suicidal, self-injury refers to direct and intentional self-harming without lethal intent, Hamza explains. Although cutting by women has received a fair amount of attention by media, non-suicidal, self-harming behaviours, or NSSI for short, are used by both sexes, albeit the behaviours differ.</p> <p>ā€œMen are more likely to use burning or self-hitting,ā€ she says, ā€œwhile women are more likely to engage in cutting and scratching. Thatā€™s why when we survey people, like students, we need to ask about a whole spectrum of behaviours.ā€</p> <p>And, for reasons that remain unclear to researchers at this time, university students are more likely to engage in NSSI than peers their same age who are not in post-secondary education, Hamza says, adding thatā€™s one of the reasons itā€™s so important for ³Ō¹Ļ±¬ĮĻ to engage in this kind of research.</p> <p>Hamza hopes her search for answers, which will start this fall with a study of ³Ō¹Ļ±¬ĮĻ students who have engaged in NSSI, will help clinicians create better interventions and lifelong coping strategies for struggling students.</p> <p>According to emotional cascade theory, some people experience negative emotions intensely, leading to rumination and more negative emotions (an emotional cascade). NSSI may serve as one way to disrupt this ā€œvicious feedback loop,ā€ while other healthier coping strategies may not provide enough distraction ā€œto interrupt that emotional cascade for some students.ā€ Finding an intervention to disrupt that feedback loop could help people engage in less destructive, more positive behaviour.</p> <p>She says she also hopes to someday do a large-scale survey, arising out of this foundational study, to follow her student subjects as they age. Perhaps like binge drinking in the early years of university, NSSI behaviour tapers off with age?</p> <p>In addition to Hamza, the recipients of this yearā€™s Connaught New Researcher Award are:</p> <h3>Dalla Lana School of Public Health</h3> <p>ā€¢&nbsp;&nbsp; &nbsp;<strong>Emily Seto</strong> of the Institute of Health Policy, Management and Evaluation for ā€œTelemonitoring in an integrated chronic disease management clinic: A new model of care for complex patients with multiple chronic conditionsā€</p> <h3>Faculty of Arts &amp; Science</h3> <p>ā€¢&nbsp;&nbsp; &nbsp;<strong>Anabela Alves dos Santos Rato </strong>of the department of Spanish &amp; Portuguese for ā€œthe role of cross-language phonetic similarity and articulatory difficulty in L2 speech learningā€</p> <p>ā€¢&nbsp;&nbsp; &nbsp;<strong>Susana Bejar</strong> of the department of linguistics for ā€œthe syntax of Georgian pseudocleftsā€</p> <p>ā€¢&nbsp;&nbsp; &nbsp;<strong>Arthur Blouin</strong> of the department of economics for ā€œthe dynamics of diversity: evidence from ancestral migrationā€</p> <p>ā€¢&nbsp;&nbsp; <strong>&nbsp;Irene Boeckmann</strong> of the department of sociology for ā€œfatherhood and menā€™s earnings from a cross-national perspectiveā€</p> <p>ā€¢&nbsp;&nbsp; &nbsp;<strong>Elisa Brilli </strong>of the department of Italian studies for ā€œDante among Augustine's readers.

Itā€™s also one of the largest perinatal centres in North America.</p> <p>ā€œThis would be the ultimate prenatal diagnostic test,ā€ says Kolomietz, who is also an associate professor in laboratory medicine and pathobiology at ³Ō¹Ļ±¬ĮĻ.</p> <p>For the past four years, her team has been collecting cervical mucosal specimens ā€“&nbsp;taken in a similar manner to a Pap smear ā€“&nbsp;which are ā€œa perfect test case for our new technology,ā€ Wheeler says.</p> <p>These&nbsp;specimens, collected five to 14 weeks after conception, contain fetal cells from placenta that is shed into the uterus. Even a small number of intact cells should be sufficient for a comprehensive whole genome analysis.</p> <p>But the wrinkle is that the specimens contain both maternal and fetal cells. ā€œIt is a needle in a haystack problem,ā€ Wheeler says.</p> <p>Isolating the individual fetal cells ā€“&nbsp;without contamination from the maternal cells or damage to their DNA ā€“&nbsp;is tricky. Using existing methods met with limited success for Kolomietz and her team. So she looked for an alternative solution and up popped Wheelerā€™s work.</p> <p>ā€œI sent Dr. Wheeler an email and we had a meeting and he was immediately excited about the project,ā€ she recalls. ā€œItā€™s been a delight to work with his group.ā€</p> <p>Using Wheelerā€™s digital microfluidic laser cell lysis platform, the fetal cells will adhere in situ and grow on a specially designed microfluidic device rather than using suspended cells in flowing tubes. The researchers will stain and mark the fetal cells and a laser will blast the cells to break them open. Tiny fluid droplets containing the cellsā€™ contents will be collected and analyzed for genetic anomalies.</p> <p>ā€œIt sounds a little science fictiony,ā€ he admits but says ā€œoptimisticallyā€ the technology could be widely available in five yearsā€™ time for pregnant women if the tests function well.</p> <p>Kolomietz is hopeful it could be even sooner.</p> <p>ā€œOnce we solve the problem of cell isolation, everything else is in place,ā€ she said, envisioning a future that sees women having the specimens collected by a nurse or family doctor during a regular Pap smear as soon as their pregnancy is confirmed.</p> <p>And, the platformā€™s prenatal usage is only the beginning.</p> <p>ā€œWe propose that this system may be useful for evaluating adherent-cell heterogeneity for a wide range of applications,ā€ Wheeler says. ā€œThat is one of the reasons that we are grateful for this funding from the Connaught Foundation, which will allow us to explore.ā€ &nbsp;</p> <p>In addition to Wheeler, the recipients of this yearā€™s Connaught Innovation Award are:</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__3322 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/RobertBonin_1.jpg" style="width: 245px;

The award,&nbsp;funded by ³Ō¹Ļ±¬ĮĻā€™s Connaught Fund, was established in 2011 to support interdisciplinary approaches to problems of global significance.&nbsp;Proposals come from the ³Ō¹Ļ±¬ĮĻ research community, involve&nbsp;large teams from multiple disciplines&nbsp;and are subjected to the highest level of international peer review.</p> <h3><a href="http://news.utoronto.ca/could-carbon-dioxide-be-solution-climate-change">Read more about projects backed by the&nbsp;Connaught Global Challenge Award</a></h3> <p>As more people and businesses move crucial operations online, digital security has become a&nbsp;challenge of global significance.&nbsp;Modern&nbsp;encryption ciphers can only be broken with powerful computers, much faster than those commercially available today. Quantum computing and quantum cryptography harness the physical laws of quantum mechanics to provide both speed and security improvements many orders of magnitude better than todayā€™s state-of-the-art.</p> <p>ā€œA technological platform that provides a significant leap forward is sorely needed,ā€ says Helmy. ā€œMy personal vision is for a quantum Internet that can go farther beyond quantum-based security ā€“&nbsp;that can afford distributed quantum information processing, where quantum computers are connected by quantum communications.ā€</p> <p>Helmy is leading the effort to gather a critical mass of quantum Internet researchers and identify pressing research questions in this field. The group includes investigators from across ³Ō¹Ļ±¬ĮĻ, including in The Edward S. Rogers Sr. Department of Electrical &amp; Computer Engineering, physics, and chemistry, as well as industry partners from Nippon Telegraph and Telephone in Japan and Burnaby, B.C.-based quantum-computing company D-Wave Systems.</p> <p>One of the groupā€™s first objectives, says Helmy, will be to study how quantum states encoded in light, as photons, can robustly exchange information, with quantum states generated and manipulated in matter, as ions.</p> <p>ā€œCurrently thereā€™s no robust way to couple quantum states of the two systems&nbsp;ā€“&nbsp;photons and ions&nbsp;ā€“&nbsp;whereby one can share the generated quantum states between different network nodes,ā€ says Helmy. ā€œWhile there are promising approaches out there, they mostly lack the practical finesse, which propels them to fuel demonstrations out of the lab and into the field.ā€</p> <p>The Connaught Fund, currently valued at more than $105 million, was founded in 1972 from the sale of the Connaught Medical Research Laboratories for $29 million. The labs had produced vaccines and, notably, insulin after it was discovered by ³Ō¹Ļ±¬ĮĻ researchers <strong>Frederick Banting</strong> and <strong>Charles Best</strong> in 1921. The Connaught fund has since awarded more than $135 million to ³Ō¹Ļ±¬ĮĻ scholars and&nbsp;is the largest internal university research funding program in Canada.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/2016-01-07-Helmy-sized.jpg</div> </div> Thu, 07 Jan 2016 16:56:03 +0000 sgupta 7560 at Could carbon dioxide be the solution to climate change? /news/could-carbon-dioxide-be-solution-climate-change <span class="field field--name-title field--type-string field--label-hidden">Could carbon dioxide be the solution to climate change?</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2015-11-26T03:55:18-05:00" title="Thursday, November 26, 2015 - 03:55" class="datetime">Thu, 11/26/2015 - 03:55</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Artist's rendering of Australia's daily carbon dioxide emissions (image courtesy Carbon Visuals via Flickr)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/patchen-barss" hreflang="en">Patchen Barss</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Patchen Barss</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/awards" hreflang="en">Awards</a></div> <div class="field__item"><a href="/news/tags/climate-change" hreflang="en">Climate Change</a></div> <div class="field__item"><a href="/news/tags/connaught" hreflang="en">Connaught</a></div> <div class="field__item"><a href="/news/tags/environment" hreflang="en">Environment</a></div> <div class="field__item"><a href="/news/tags/more-news" hreflang="en">More News</a></div> <div class="field__item"><a href="/news/tags/research" hreflang="en">Research</a></div> <div class="field__item"><a href="/news/tags/sustainability" hreflang="en">Sustainability</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">Connaught Global Challenge Award goes to solar fuels cluster </div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>In the drama of climate change, carbon dioxide has long played the role of arch-villain.</p> <p>Now, though, Canada Research Chair of Materials Chemistry and Nanochemistry and <a href="http://www.provost.utoronto.ca/awards/uprofessors.htm">University Professor</a> of Chemistry <strong>Geoffrey Ozin</strong> wants to recast the infamous greenhouse-gas scoundrel in the role of hero, placing it centre stage in the development of carbon-neutral, renewable energy. &nbsp;</p> <p>And thanks to an investment of $1 million from the Connaught Global Challenge Award program, he is setting out to do just that.</p> <p>ā€œThe public has heard of carbon capture and storage,ā€ Ozin says. ā€œThey havenā€™t heard about carbon capture and utilization.ā€</p> <p>Carbon dioxide, it turns out, plays many roles other than heating the planet. Itā€™s used to manufacture industrial chemicals and polymers. Itā€™s a component in urea, a key part of many fertilizers. &nbsp;</p> <p>And, it can be used to make methane and diesel fuels.&nbsp;</p> <p>ā€œCarbon dioxide already forms the basis of a megaton industry for making chemicals, materials, cement and fertilizers,ā€ says Ozin. ā€œWhy not use it as much as you can? You could build a global economy on a resource thatā€™s all around us. And if you happen to use Gigatons every year, then you could keep atmospheric carbon dioxide levels at sustainable levels indefinitely.ā€</p> <p><strong><img alt="head shot style photo of Ozin" src="/sites/default/files/2015-11-26-ozin-embed.jpg" style="width: 250px; height: 300px; margin: 10px; float: right;"></strong>Ozin (pictured at right) is leading a multidisciplinary team, dubbed ā€œThe ³Ō¹Ļ±¬ĮĻ Solar Fuels Clusterā€ on a quest to develop a process for converting carbon dioxide into an energy-rich renewable fuel, using a carbon-neutral cycle. &nbsp;</p> <p>Ozinā€™s approach fits the nature of the Global Challenge Award perfectly. The award was created in 2011 to bring together the universityā€™s leading researchers from multiple disciplines with innovators from other sectors to enhance ³Ō¹Ļ±¬ĮĻā€™s contributions to issues facing global society. Proposals come from the ³Ō¹Ļ±¬ĮĻ research community, involving large interdisciplinary teams and are subjected to the highest level of international peer review. &nbsp;&nbsp;</p> <p>The Connaught Fund is currently valued at more than $105 million. It was founded in 1972 from the sale of the Connaught Laboratories for $29 million. The labs had produced vaccines and, notably, insulin after it was discovered by ³Ō¹Ļ±¬ĮĻ researchers Frederick Banting and Charles Best in 1921. The Connaught fund has since awarded more than $135 million to ³Ō¹Ļ±¬ĮĻ scholars. &nbsp;</p> <p>ā€œThe Connaught Fund has always been focused on enabling research relevant to society,ā€ says Professor <strong>Vivek Goel</strong>, ³Ō¹Ļ±¬ĮĻā€™s vice-president, research and innovation. ā€œThe goal of the Global Challenge Award provides a level of funding that helps our researchers go very deeply into a problem that affects everyone on the planet and create progress on solutions to that problem.&nbsp;</p> <p>ā€œThese challenges demand experts from a wide range of areas coming together ā€“ no sole scholar can do it alone. The focus of the Ozin team on renewable energy will addressone of the great problems of our time. The Connaught Committee believes the wide range of expertise on Geoffā€™s team can deliver important advances on this vital topic.ā€</p> <p>Ozin is joined in the project by</p> <ul> <li><strong>Charles Mims</strong>, chemical engineering and applied chemistry (CEAC)</li> <li><strong>Nazir Kherani</strong>, materials science and engineering (MSE) and electrical and computer engineering (MSE)</li> <li><strong>Douglas Perovic</strong>, MSE</li> <li><strong>Cathy Chin</strong>, CEAC</li> <li><strong>Ben Hatton</strong>, MSE</li> <li><strong>Chandra Veer Singh</strong>, MSE</li> <li><strong>Zhenghong Lu</strong>, MSE</li> </ul> <p>Ozin says people tend to view carbon dioxide as a waste product because itā€™s whatā€™s left over after burning fuel or breathing air. Itā€™s a very stable molecule, which doesnā€™t react easily with other materials. But given the right catalyst, it can be broken up and transformed into carbon monoxide, methane, methanol, ethylene, formic acid and other highly useful chemicals.&nbsp;</p> <p>Finding the right catalyst involves more than identifying substances that can coax reactions out of CO2. Ozin researches how to shape materials on a nanoscopic scale, creating structures a few billionths of a metre in size. Nanostructuring can do things like maximize the surface area where gas and catalyst interact. More surface area means more chemical reaction.&nbsp;</p> <p>ā€œA carbon dioxide economy will depend on nanostructured forms of semiconductors and metals,ā€ Ozin says. ā€œWe foresee a sunlight-assisted conversion of gaseous CO2 to fuel, using catalysis to create a ā€˜solar refineryā€™ that is, critically, predicated on existing industrial infrastructure and combustion processes.ā€</p> <p>Ozin first turned his attention to this problem seven years ago when he was 65 years old. He says it sometimes feels odd to be working on something so tied to immediately pressing global challenges, where mere discovery is only a part of the recipe on a long road to success.&nbsp;</p> <p>ā€œIā€™m an academic used to doing basic science,ā€ he says. ā€œBut for global industry, you have to create materials that are not just different from what already exists, but that do a particular job better. You have to boil things down to simpler, scalable components that are abundant, low-cost, and stable under every imaginable condition ā€“ in varying sunlight levels, at different temperatures, and under reaction.ā€&nbsp;</p> <p>Despite the challenges, he remains convinced that science and engineering can reform CO2 into a productive part of global society.</p> <p>ā€œI believe that carbon dioxide should be viewed as more than a combustion waste product of fossil fuel,ā€ he says. ā€œWe should think of it as a chemical resource to be harvested and recycled into renewable fuel.ā€</p> <p>His mantra is ā€œsolar fuels from the sun not fossil fuels from the earthā€.&nbsp;</p> <p>The support from the Connaught Fund runs from September 2015 to December 2017.&nbsp;</p> <p>The Connaught Committee also made a $170,000 Global Challenge Award to a second interdisciplinary team led by Professor <strong>Amr Helmy</strong> of electrical and computer engineering for his project entitled The Quantum Internet: Charting the Critical Path. <em>&nbsp;³Ō¹Ļ±¬ĮĻ</em> will post a feature on this project soon. &nbsp;</p> <p>(<a href="https://www.flickr.com/photos/carbonquilt/12813779003/in/photolist-kwiY5c-6DJRP7-b7RKpk-kwiPYx-eo8f69-6DEGpi-24LrXj-5uJBmm-5d4nQX-7zDWyU-8wCAf1-75hwCr-9aee37-eo1zJh-eBH8eR-p8QDnd-75mohu-75monA-7LYTD4-8CAubm-eBHnuM-ktJ4e-pqkcv4-rAyGDg-75mow9-9nBqhg-b2XJB6-hDJ3sh-hDHZsE-hDHWDJ-pqFxe2-hFKuc8-hFH5dD-cRHis-d4au1L-a19cFD-a19cHZ-a1bgBC-a19cvH-hEPoqM-hEQJdP-hEQJ7B-t8Kifv-bbJCyn-6eZTP-hFEBoy-hFDGsn-hFFBTM-hFFAPd-hFGYje">See the original image of Australia's&nbsp;carbon emissions from&nbsp;Carbon Visuals on Flickr</a>)</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/2015-11-26-carbond-dioxide-ozin.jpg</div> </div> Thu, 26 Nov 2015 08:55:18 +0000 sgupta 7475 at What nature can teach us about solar energy /news/what-nature-can-teach-us-about-solar-energy <span class="field field--name-title field--type-string field--label-hidden">What nature can teach us about solar energy</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2014-09-29T09:11:26-04:00" title="Monday, September 29, 2014 -

These arenā€™t just leaders from one field, theyā€™re from a whole range of different fields, and theyā€™re coming here to learn from each other, to work towards a common goal.</p> <p> People in the field of quantum biology and photobiology ā€“ specialists in the mechanisms underpinning photosynthesis ā€“ have been saying for a long time that we should look to nature to make our energy production more efficient, but nobodyā€™s been asking how. At this symposium, we are coming together to learn from each other. Our goal is to see projects and partnerships emerge from it that will lead to further progress in solar energy ā€“ both electricity and stored fuels.</p> <p> <strong>With all of these world experts converging in Toronto, could you share who at the University of Toronto and across the city may benefit from attending?</strong></p> <p> The symposium is very inclusive. Many of the attendees will be engineering and science graduate students, but itā€™s open across campus and appeals to a number of different fields. The more people who join from different academic and professional backgrounds the better, from physicists to materials scientists to political and environmental science students interested in energy policy.</p> <p> <strong>Part of the symposium is a public lecture with Sir Richard Friend. Who is Sir Friend and what can we expect from his lecture?</strong></p> <p> [Sir Richard Friend] is a pioneer in plastic electronics, or flexible electronics. Heā€™s had a tremendous amount of global success with turning flexible plastic materials into active devices for displays, lasing&nbsp;and energy conversion.</p> <p> Sparked by the ideas of photobiologists, Richard says in the abstract for his lecture that, when it comes to solar energy, nature has us beat every time: they reproduce and propagate naturally with only the power of the sun; theyā€™re extremely efficient at using a broad spectrum of light and they remove carbon dioxide from the air in the process.</p> <p> He is both inspiring and inspired by the general thrust of the symposium. We invited him to think big, to lay out the vision for the next few decades of energy generation, in particular in the role of renewable resources and natural energy production.</p> <p> <strong>What are the intended outcomes of this conference?</strong></p> <p> We seek to spark a new field. This symposium is, at its core, a conversation between some of the worldā€™s energy leaders, and the next stage will be to begin collaboration across traditional [research] boundaries to solve problems together. When the conference is done, weā€™ll set to work towards these goals ā€“ advances in clean energy technology that are crucial to societyā€™s future.</p> <p> In my research group, we create solar cells based on plastic flexible spray coating. We make cells that are particularly good at absorbing more of the sunā€™s spectrum, from the visible into the infrared. We get our inspiration from nature, because nature is great at harvesting the full rainbow spectrum of sun. Algae, for example, stack themselves in layers ā€“ a green layer, a blue layer, and so on ā€“ until they make up the full spectrum. Theyā€™re extremely efficient in handling the sunā€™s broad spectrum, and we gain inspiration and learn from them.</p> <p> In addition, we work with soft materials that you spray down as a coating. But because theyā€™re soft, they have all sorts of imperfections. This makes it hard for electrons to travel across their surface, but plants have these same imperfections and they transport energy very well. Weā€™re trying to improve our electron transport abilities by looking at how nature does it. Weā€™re also looking into antenna technology, modeling again off of plants, which will increase the rate at which our materials are able to absorb light.</p> <p> <a href="http://www.engineering.utoronto.ca/About/Engineering_Events/Bio-Inspired_Ideas_for_Sustainable_Energy_-_Connaught_Symposium.htm">Learn more about the Connaught Global Challenge Symposium: Bio-Inspired Ideas for Sustainable Energy</a>.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-picpath field--type-string field--label-above"> <div class="field__label">picpath</div> <div class="field__item">sites/default/files/2014-09-26-sargent.jpg</div> </div> Mon, 29 Sep 2014 13:11:26 +0000 sgupta 6515 at Origin story: how the Dalla Lana School of Public Health began /news/origin-story-how-dalla-lana-school-public-health-began <span class="field field--name-title field--type-string field--label-hidden">Origin story: how the Dalla Lana School of Public Health began</span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2014-05-02T11:33:25-04:00" title="Friday, May 2, 2014 - 11:33" class="datetime">Fri, 05/02/2014 - 11:33</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Dean Howard Hu with portrait of Gerry FitzGerald</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/nicole-bodnar" hreflang="en">Nicole Bodnar</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Nicole Bodnar</div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/dalla-lana-school-public-health" hreflang="en">Dalla Lana School of Public Health</a></div> <div class="field__item"><a href="/news/tags/health" hreflang="en">Health</a></div> <div class="field__item"><a href="/news/tags/medicine" hreflang="en">Medicine</a></div> <div class="field__item"><a href="/news/tags/connaught" hreflang="en">Connaught</a></div> <div class="field__item"><a href="/news/tags/features" hreflang="en">Features</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">Fighting germs, manufacturing vaccines and distributing them for free</div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>One hundred years ago, in a city rife with infectious disease, Dr. <strong>John Gerald</strong> (ā€œ<strong>Gerry</strong>ā€) <strong>FitzGerald</strong> opened a small laboratory in the basement of ³Ō¹Ļ±¬ĮĻā€™s Medical Building.</p> <p>The lab succeeded in controlling and even eradicating deadly infectious diseases such as diphtheria and smallpox ā€“ and it planted an early seed for Canadaā€™s publicly-funded health care system.</p> <p>May 1, 2014 marks the centenary of the founding of that lab: the University of Toronto Antitoxin Laboratory, predecessor of the Dalla Lana School of Public Health. In his award-winning book, <em>What Disturbs Our Blood,</em> James FitzGerald, the grandson of ā€œCanadaā€™s public health visionary,ā€ traces the full story.</p> <p>ā€œMy grandfather and his colleagues,ā€ he writes, ā€œtransformed the field of public health from an isolated grassroots movement into a modern, specialized, state-run bureaucracy, stretching like a giant safety net from the Atlantic to Pacific Oceans.ā€</p> <p>Gerry FitzGeraldā€™s fascination with the emerging germ theory of disease ā€” the concept that conditions are caused by micro-organisms or pathogens that infect a host ā€” propelled him into medical school at age 16 in 1899. After studying at elite international medical institutions including Harvard, Berkeley and the Pasteur Institute, FitzGerald returned home in 1913 to pitch a radical idea to the University of Toronto Board of Governors: he would manufacture vaccines and antitoxins for free distribution to all Canadians as a public service.</p> <p>ā€œHe had the values of a scholar, the drive of an entrepreneur and a highly developed social conscience,ā€ said James FitzGerald.</p> <p>With the epochal discovery of insulin by Banting and Best at ³Ō¹Ļ±¬ĮĻ in 1922, the young lab ā€” now renamed the Connaught Laboratories ā€” drew international attention and fresh philanthropic support. The Rockefeller Foundation donated $1.2-million (equivalent to roughly $30-million today) to establish the University of Toronto School of Hygiene, serving as the academic arm of the labs.</p> <p>Opening on College Street in 1927, it was only the third school of hygiene in North America at the time, alongside Johns Hopkins and Harvard.</p> <p>FitzGeraldā€™s vision for the Connaught Labs and the School of Hygiene was three-pronged: the preparation of a host of low-cost, high quality preventative medicines for free national distribution through government departments of health; a research arm to develop new products to meet the constant threat of infectious diseases; and undergraduate and graduate education to pass on the torch of knowledge to future generations of public health workers.</p> <p>By the mid-1930s, the School was a world leader in sanitation science, nutrition and vaccine development.&nbsp; Not only did all provinces distribute Connaught products, but the lab built a thriving export market in countries as distant as New Zealand, China and the Caribbean.</p> <p>As the first commercial drug firm operated by an academic institution, the Connaught Laboratories helped establish Canada as number one in the world in preventative medicine and public health. By 1940, the year of FitzGeraldā€™s death, Hamilton and Toronto were declared the first cities in the world to be diphtheria-free. FitzGerald truly delivered on his vision of health care ā€œwithin reach of everyone.ā€</p> <p>Over the ensuing decades, the Connaught Labs and School of Hygiene added to its list of global achievements, including the ongoing mass production and world-wide distribution of insulin; the production of penicillin during World War II; the Jonas Salk polio vaccine in the 1950s and the invention of multivalent vaccines; and spearheading the conquest of smallpox in the 1970s.</p> <p>The 1970s signalled change on many fronts. When communicable diseases seemed vanquished by vaccines and antibiotics, the Connaught Laboratories spun off into private industry in 1972, and ³Ō¹Ļ±¬ĮĻ transitioned the School of Hygiene into a community health department in the Faculty of Medicine. The Faculty of Medicine integration helped to ensure that all medical students received public health education and provided a framework for community health centers and advocacy for health and social reform.</p> <p>ā€œIn many ways, the public health challenges faced by FitzGeraldā€™s generation are not much different than those we face today,ā€ observes <strong>Howard Hu</strong>, dean of the Dalla Lana School of Public Health.</p> <p>ā€œOur world is crowded, diverse, aging, urbanized, polluted, hot, thirsty, hungry and debt-ridden.&nbsp; As William Foege, former director of the U.S. Center for Disease Control and Prevention, put it, health in the 20th century can be summed up in four words: spectacular progress, spectacular inequities,ā€ said Hu.</p> <p>The SARS crisis in 2003 led to a rebirth of public health academics in Canada.

With Bohaker's permission, ³Ō¹Ļ±¬ĮĻ is republishing the letter here:</em></p> <p>In 1963 my father was a 21 year old RCMP constable stationed in Hopedale, Labrador, in a two-man detachment responsible for policing a large region from Makkovik in the south to Davis Inlet in the north. In December of that year he developed a flu-like illness and lost weight rapidly. In two short weeks, he lost 35 lbs, a once strapping now gaunt 6'1" officer. In the first week of January he was shipped out for medical evaluation at the RCAF hospital in Goose Bay.</p> <p>The base doctor thought he had just had a bad flu and recommended he return to work, but before Dad could fly back his condition worsened, and he was sent to see Dr. W. Anthony Paddon at the Grenfell Mission Hospital at North West River (about 30 miles east of Goose Bay). Dr. Paddon (who went on to become the Lieutenant Governor of Newfoundland) immediately realized that my father had actually developed Type 1 diabetes, a complete inability of the body to produce insulin and therefore to metabolize sugar.</p> <p>This disease was once lethal but thanks to the Nobel prize-winning research conducted at the University of Toronto in 1921-22, diabetes had become a controllable condition through daily injections of insulin derived from cattle and pigs. My father received his first shot of life-saving insulin on Jan 14, 1964, half an hour after arriving at the Mission hospital. After a five-day stay he was then shipped out to hospital in St. John's, Newfoundland where he remained for three weeks before returning to duty. He later married my mother, whom he had met during his time in Hopedale. She was one of two local schoolteachers.</p> <p>As a child I grew up hearing the remarkable story of the discovery of insulin, and I certainly knew that my own existence was due to the substance in the multiple needles that my father injected every day. On day trips to the Royal Ontario Museum from our home in Oshawa, we invariably walked through ³Ō¹Ļ±¬ĮĻ's campus as well, past the Medical Sciences Buildings which is the original location of Professor John MacLeodā€™s laboratory, where Dr. Frederick Banting conducted his experiments alongside research assistant Charles Best and biochemist Bertram Collip.&nbsp;</p> <p><img alt src="/sites/default/files/2014-02-04-bohaker-and-dad.jpg" style="width: 400px; margin: 10px; float: right; height: 267px;">I also heard of course about the importance of ³Ō¹Ļ±¬ĮĻ's Connaught laboratory which was the first to mass-produce insulin, along with other life-saving medications and vaccines, and which made them available to all at affordable prices. My father did not complete high school before he entered the RCMP, but he certainly impressed upon both my brother and me the importance that basic research at universities contributes to society, and in particular of course research at the University of Toronto.</p> <p>There was, therefore, extra cause for celebration when I was offered a tenure-stream position in History at the University of Toronto. And I remember phoning my father shortly after my arrival here with the exciting news that the initial research grant awarded to new faculty came from the Connaught fund, an endowment created by the University's sale of the Connaught laboratories in 1971 to the private sector. The discovery and production of insulin was continuing to fund new research.</p> <p>On January 14th, 2014, I attended a reception held by the President and Provost to congratulate those of us who had achieved tenure in the past year. For me, it was a doubly special day ā€“ as the 14th was also the 50th anniversary of my fatherā€™s diagnosis and first insulin injection.</p> <p>In the 1960s, insulin saved lives, but my father still knew and expected that his life would be shorter and full of additional medication complications as a result of his disease. We grew up anticipating that my father would be outlived by our grandfather. But years of continued research and refinements in diabetic treatment, and the development of humulin, synthetic human insulin, have significantly changed that original picture. My father, now 71, has recently had cataract surgery, and his knees are a bit arthritic. Not complications of diabetes, but now-welcomed signs of normal aging. And he's very much enjoying his nearly four-year old grandson.</p> <p>At times of fiscal restraint and focus on applied research with immediate commercial applications, my father's story reminds me about the importance of universities as places that create the space for big "what if" and "I wonder" questions, like the one Dr.<strong> Frederick Banting</strong> asked, on a hunch, about the cause of diabetes. Basic research sometimes results in dead ends, but sometimes results in the kinds of remarkable discoveries that makes new and different futures possible, including, I am keenly aware, my own!</p> <div> <em>Professor Heidi Bohaker joined ³Ō¹Ļ±¬ĮĻ in 2007 following a SSHRC post-postdoctoral fellowship at Carleton University.
