With the latest announcement, there are now eight CREATE grants active across 老司机直播 Engineering.</p> <p>鈥淧rofessors Herman and Radisic are leading innovative programs that address key challenges in communications technology and human health,鈥 said Professor <strong>Ted Sargent</strong>, vice-dean of research in the Faculty of Applied Science &amp; Engineering. 鈥淭his support will help us nurture a new generation of engineering leaders who can bring solutions from the laboratory into the marketplace.鈥</p> <p>Learn more about the projects below:</p> <h3><strong>Professor Peter Herman 鈥 Guiding light for communications, sensing and more</strong></h3> <p>Herman鈥檚 research focuses on materials and techniques to control the flow of light. This includes fibre optics, which revolutionized telecommunications in the 1980s by replacing metal wires with faster, more efficient light-conducting fibres.</p> <p>鈥淭oday, that same story is being played out in the data centres that power cloud computing,鈥 said Herman. 鈥淓lectronic cabling is becoming a bottleneck, and the wires can only be packed so closely before signals are interfering. If you can switch it over to optical, it will reduce the cost and allow more information to flow.鈥</p> <p>Optics have many other applications as well: optical sensors are used to monitor bridges, pipelines and even airplane wings, providing feedback on when they need to be repaired or replaced. Optics also enable ever-smaller medical probes that can image the inside of the body and reduce the need for invasive surgery. In this way, guided light underpins the connectivity that will support the Internet of Things, a connected network of everyday devices, from clothing to appliances to vehicles, that can send and receive data.</p> <p>Herman is leading a team that includes Professors <strong>Stewart Aitchison</strong>, <strong>Joyce Poon</strong> and<strong> Li Qian</strong>, as well as collaborators at Universit茅 Laval, and Quebec鈥檚 Institut national de la recherche scientifique (INRS). The team also includes several crucial researchers from Friedrich Schiller University Jena, a German research university.</p> <p>鈥淛ena is a world-leading place for optics research and manufacturing 鈥 they call it the City of Light,鈥 said Herman. 鈥淲e want to introduce our students, early on in their graduate studies, to the successful model they use to build links between academia and photonics companies. We will then follow up in Canada with links to Canadian optics industry.鈥 The experience will help the students learn how to translate their discoveries into new products, either for existing companies or commercial ventures that they themselves will create.</p> <h3><strong>Professor Milica Radisic 鈥 Lab-grown human tissues for drug testing and organ repair</strong></h3> <p>Radisic and her team focus on growing human tissues outside the body. They <a href="http://news.utoronto.ca/u-t-engineers-create-lab-grown-heart-and-liver-tissue-drug-testing-and-more">recently unveiled the AngioChip</a>, a system for growing realistic vascularized heart and liver tissues in the lab. These engineered tissues offer an effective way to test potential drug molecules and determine their effect on these organs, an application that is already being commercialized through the spin-off company <a href="http://www.hhvc.com/portfolio-item/tara-biosystems-inc/">TARA Biosystems</a>. Eventually, they could be implanted into the body to repair or replace damaged organs.</p> <p>The new funding will leverage the success of AngioChip鈥檚 commercialization. 鈥淚n contrast to other CREATE programs that provide training through industrial internships, our training here will focus on developing a company,鈥 said Radisic. 鈥淥ur students will learn how to apply for patents, develop a business plan, make an effective fundraising pitch and more.鈥</p> <p>Radisic doesn鈥檛 expect every student to create a startup, and she knows that not every new business succeeds. Nevertheless, she feels that entrepreneurship training for engineering graduate students is a critical part of building strong Canadian industries.</p> <p>鈥淭he knowledge they gain will be transferable beyond their field,鈥 she said. 鈥淚n time, I expect to see them in roles like chief executive officer, chief scientific officer, senior scientist, consultants and IP specialists.鈥</p> <p>The project includes 11 primary investigators from 老司机直播: Professors <strong>Craig Simmons</strong>, <strong>Axel Guenther</strong>, <strong>Paul Santerre</strong>, <strong>Alison McGuigan</strong>, <strong>Arun Ramchandran</strong>, <strong>Penney Gilbert</strong>,<strong> Edmond Young</strong>,<strong> Aaron Wheeler</strong>,<strong> Sara Vasconcelos</strong> and <strong>Eugenia Kumacheva</strong>, as well as collaborators as the Universit茅 Laval, the University of Ottawa, McMaster University, Queen鈥檚 University, Ryerson University and the University of Victoria. It also includes support from the<a href="http://entrepreneurs.utoronto.ca/"> Banting &amp; Best Centre for Innovation &amp; Entrepreneurship</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> Thu, 14 Apr 2016 20:24:16 +0000 krisha 13837 at Joe Pennachetti on cities and the role of the University of Toronto /news/joe-pennachetti-cities-and-role-university-toronto <span class="field field--name-title field--type-string field--label-hidden">Joe Pennachetti on cities and the role of the University of Toronto</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="2016-04-14T04:38:26-04:00" title="Thursday, April 14, 2016 - 04:38" class="datetime">Thu, 04/14/2016 - 04:38</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">Joe Pennachetti, at the Global Cities Summit hosted by 老司机直播's Global Cities Institute in May 2014, where the creation of the World Council on City Data (WCCD) to globally implement ISO 37120 was announced (photo courtesy the WCCD)</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/elizabeth-church" hreflang="en">Elizabeth Church</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">Elizabeth Church</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/cities" hreflang="en">Cities</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/munk-school-global-affairs-public-policy" hreflang="en">Munk School of Global Affairs &amp; Public Policy</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">Former City Manager will be in conversation today with CBC Radio's Matt Galloway at the Munk School of Global Affairs</div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><strong>Joe Pennachetti</strong>, Toronto鈥檚 former top civil servant, says universities are the 鈥渋deal forum,鈥 for sharing information and innovative practices among cities across Canada and around the world. &nbsp;</p> <p>Pennachetti&nbsp;<a href="http://news.utoronto.ca/cities-expert-joe-pennachetti-joins-university-toronto-0">joined the University of Toronto in 2015</a>&nbsp;as a senior adviser at the Institute on Municipal Finance &amp; Governance (IMFG) and the School of Public Policy &amp; Governance (SPPG) and as a senior adviser at the &nbsp;Global Cities Institute and executive adviser to the World Council on City Data.&nbsp;</p> <p>Both are places he turned to, he says, for expertise and research to guide policy as city manager of Canada鈥檚 largest city. In his new role at 老司机直播, he is encouraging others to do the same.</p> <p>Pennachatti&nbsp;will discuss his views on policy making in civic government with CBC radio host Matt Galloway today at a sold-out forum at 老司机直播鈥檚 Munk School of Global Affairs. The event is&nbsp;co-sponsored by the IMFG&nbsp;and the School of Public Policy and Governance (SPPG) at the University of Toronto.&nbsp;&nbsp;</p> <p>In advance of that event, he spoke to <em>老司机直播 News</em> about the role he sees for 老司机直播 in supporting cities and the increasing importance of civic government.</p> <hr> <p><strong>Tell us&nbsp;about your new role at 老司机直播.&nbsp;</strong><br> I鈥檝e had a relationship with the both the Global&nbsp;Cities Institute and the Institute on Municipal Finance and Governance for more than a decade. To me, the partnership was invaluable to get the best possible information and data that鈥檚 out there 鈥 in Ontario, Canada, the globe. Any city with limited staff could never do the global research that they are doing. &nbsp;I am hoping to make that tie between municipalities and the university.&nbsp;</p> <p><strong>From your experience, what role do you see for 老司机直播 to help cities?</strong><br> How we can learn from one another as cities, that鈥檚 where a university is the ideal forum for pulling it all together. At the end of the day, it is this type of research that is going to be invaluable to cities. &nbsp;You start looking at the data and you solve problems that exist today and you are able to adapt to the challenges of the future, as well.&nbsp;</p> <p><strong>The federal government is about to make major investments in infrastructure. You were City Manager in Toronto during the last wave of federal infrastructure spending. &nbsp;What鈥檚 your take on this latest investment?</strong><br> I鈥檝e never been so optimistic about the true collaboration of funding from the federal level to cities in Canada. &nbsp;And don鈥檛 forget the province, as well. &nbsp;I think they have acknowledged that the property tax in cities can鈥檛 fund the tens of billions of dollars in projects that are needed to meet new growth, especially transit. I think it is finally going to happen over the next 10 to 20 years.&nbsp;</p> <p><strong>Can we take the politics out of infrastructure funding?&nbsp;</strong><br> I think you can take much of the politics out by coming up with a good sound allocation formula and ensuring that municipalities have input on what they deem to be priority projects. It should be: Here is a 10 year plan on funding. Give us your projects. Match them up. It is not rocket science.&nbsp;</p> <p><strong>What is your advice to cities, given your experience?&nbsp;</strong><br> There is a huge window of opportunity. Don鈥檛 blow it. Because there is a strong political will aligned with a process, I think it is going to happen. All governments have to be seen working together. We have to be viewed by the public, the average businesses and resident as one government. &nbsp;Cities deliver the lion鈥檚 share of services. The only thing that is hindering that is the proper mix of funding sources.&nbsp;</p> <p><strong>What about revenue tools such as tolls and high occupancy lanes? Will people ever be ready to have a discussion about new sources of funding? </strong>&nbsp;<br> It really has to be provincial governments sitting down with cities. Call it a funding summit. &nbsp;You need an intergovernmental summit where cities are equal and you work out the money that is coming from the provincial and the federal government. If it means an extra 5 cents fuel tax or some toll money then so be it instead of dancing around studies every year. We need to come up with a mechanism, at least in Ontario if not across the country, of how we are going to fund these mega projects over the next 30 years.</p> <p><strong>Is this a time when the municipal level of government is coming into its own?</strong><br> No ifs ands or buts. Thirty-nine years ago when I started in Edmonton and up until about 10 years ago we were referred to as 鈥渢he third level of government.鈥 That used to really upset me, but that鈥檚 the way it was. We were treated that way.&nbsp;</p> <p>I feel strongly in the 39 years that I have been in this weird municipal world it has almost turned on its head. I believe we are treated equally now. For the average resident we deliver the core services 鈥 water, sewers, transportation, emergency services. The balance of the 21th century is going to be about urbanization. It already is.</p> <p>Cities are the future. That term is used a lot and it is real. That鈥檚 why I believe strongly that the partnership among the three levels of government has to happen now. It has to be real. It has to lay out long- term plans that will avoid the infighting and bickering that has happened in the past. We have made huge strides with the collaboration of three levels of government. We have to continue it so we are really true partners and it is not just words.&nbsp;</p> <p>&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> <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/2016-04-14-pennachetti-sized.jpg</div> </div> Thu, 14 Apr 2016 08:38:26 +0000 sgupta 7806 at 老司机直播 student Dinuk Wijeratne wins Juno Award /news/u-ts-dinuk-wijeratne-wins-classical-composition-year-juno-award <span class="field field--name-title field--type-string field--label-hidden">老司机直播 student Dinuk Wijeratne wins Juno Award</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="2016-04-05T07:57:17-04:00" title="Tuesday, April 5, 2016 - 07:57" class="datetime">Tue, 04/05/2016 - 07:57</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">Dinuk Wijeratne (photo by Michelle Doucette)</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/jessica-lewis" hreflang="en">Jessica Lewis</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">Jessica Lewis</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/more-news" hreflang="en">More News</a></div> <div class="field__item"><a href="/news/tags/faculty-music" hreflang="en">Faculty of Music</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><strong>Dinuk Wijeratne</strong>, a current Doctor of Musical Arts candidate at the Faculty of Music, has won the Juno Award for Classical Composition of the Year with his piece 鈥淭wo Pop Songs on Antique Poems,鈥 which was featured on the Afiara Quartet鈥檚 nominated instrumental album, <em>Spin Cycle</em>.<br> <br> 鈥淚t was an honour to receive a Juno Award, and to be nominated amongst such esteemed composers in my category,鈥 said Wijeratne said, following the ceremony this past weekend.</p> <p>鈥淭he piece is very much about the collision of 'old and new,' and of very diverse influences.&nbsp;I felt very stimulated working on this music under the guidance of my dear mentor Professor <strong>Christos Hatzis</strong>, and I am so glad that at 老司机直播 I could feel free to explore the fusion of such disparate influences.鈥</p> <p>Hatzis was equally excited for Wijeratne鈥檚 win.</p> <p>鈥淚 am so proud of Dinuk鈥檚 Juno Award.

"This underlines the desperate need for global investment in health equity.鈥</p> <p>Close to 100 alumni, students and faculty attended In the Loop&nbsp;鈥 the first of a new event series hosted by the Public Health 老司机直播 Association where alumni, students and friends will learn about cutting-edge public health issues&nbsp;鈥 on March 30 at the Dalla Lana School of Public Health.</p> <p>鈥淭he biggest lesson learned from Ebola is that we need to create health systems on the basis of strong primary care with close links to public health,鈥 Upshur continued, noting that WHO officials&nbsp;declared Zika a public health emergency much sooner than they did in the context of Ebola, which accelerated the response.</p> <p>鈥淏razilian health authorities are handling this outbreak reasonably well by linking surveillance with public health action, which generates good data on which authorities can make informed policy decisions,鈥 he said.&nbsp;"And we鈥檙e seeing better forward planning from neighbouring countries like Colombia, which is very promising.鈥</p> <p>Allen, who is Public Heath Ontario鈥檚 chief microbiologist, explained that although many believed Zika arrived in South America during the 2014 World Cup in Brazil, a study published on March 24 in <em>Science </em>suggests the virus likely arrived in Brazil through increased travel patterns from the South Pacific region between May and December 2013, more than a year before the outbreak was detected.</p> <p>The study 鈥 the first genomic analysis of Zika 鈥 was conducted by a large international team of researchers, including Dalla Lana associate professor <strong>Kamran Khan</strong> and assistant professor <strong>Marisa Creatore</strong>. Read more about the study in the <em>Toronto Star</em>.</p> <p>Between 2013 and 2015, there have been more than 190,000 suspected and confirmed cases globally, with the vast majority occurring in rural areas of Brazil. Scientists believe that up to 80 per cent of people infected with Zika never experience symptoms, which means its link to microcephaly 鈥 a birth defect associated with underdeveloped brains 鈥 is particularly challenging to understand.</p> <p>鈥淢icrocephaly has many potential causes and its connection to the Zika virus is an association,鈥 said Allen, an assistant professor in 老司机直播鈥檚 department of laboratory medicine and pathobiology. 鈥淚t鈥檚 not a proven fact that mothers infected with the virus will have babies with microcephaly.鈥</p> <p>Before Zika, there were 100-150 microcephaly cases each year in Brazil. In&nbsp;2015, there were more than 5,000 cases, Allen said.</p> <p>Allen also touched on the sexual transmission of the virus. Scientists have found that the virus can be transmitted through sexual contact and it remains active in semen up to 62 days after symptom onset.

The research, which compared adults in their 20s through 70s, appears in the March issue of Social Psychology Quarterly.</p> <p>鈥淭his association between giving advice and finding meaning in life is not evident in other age groups,鈥 said <strong>Markus Schafer</strong>, an assistant professor in the department of sociology and lead author of the study.</p> <p>Unfortunately, the later years 鈥&nbsp;when people would most benefit from being a sage 鈥&nbsp;is also a time when they have fewer opportunities to dispense advice, and to less-diverse types of people.</p> <p>鈥淭he findings suggest that the developmental demands of late midlife, particularly the desire to contribute to the welfare of others and the fear of feeling 鈥榮tagnant鈥, are not well aligned with the social and demographic realities of this stage of many people鈥檚 lives,鈥 he said. 鈥淛ust when giving advice seems to be most important, opportunities for doing so seem to wane.鈥</p> <p>The study, titled 鈥淭he Age-Graded Nature of Advice: Distributional Patterns and Implications for Life Meaning,鈥 relies on a representative sample of 2,583 U.S. adults.</p> <p>Schafer and 老司机直播 PhD student<strong> Laura Upenieks</strong>, co-author of the study, found that 21 per cent of people in their 60s and 27 per cent of people 70 or older reported giving advice to no one in the previous year.

Some scholars have argued that mattering supports the idea that it is important to feel that one is meaningful, consequential and can have influence on other people in various ways, including by providing advice. It is this feeling of mattering that seems to be most under threat during late-middle age when many people retire and enter the 鈥渆mpty nest鈥 phase of life, according to Schafer.</p> <p>Such research is particularly relevant given demographics: in 2015, for the first time, more Canadians were 65 years of age and older than were younger than 15 years of age, and the trend is only set to increase.</p> <p>A number of researchers across the Faculty of Arts &amp; Science are engaged in researching issues relevant to an aging population. <strong>Alison Chasteen</strong> in the department of psychology, for example, recently uncovered a correlation between the abilities of older adults to hear and remember with how they feel about getting older, as well as the social factors that influence those perceptions about aging.

They are the most common landform across large areas of northern North America and Europe, marking the footprint of great sheets that formed during past ice ages.&nbsp;</p> <p>The question that鈥檚 stumped geologists since drumlins were first studied more than 150 years ago is whether they were built up progressively or sculpted out of older sediment. Eyles and his team including PhD candidate <strong>Shane Sookhan</strong> and undergraduate student<strong> Lina Arbelaez-Moreno</strong> were able to determine that drumlins are simply streamlined 鈥渋slands鈥 of sediment that are often bisected to form kilometre-long skinny megaridges.</p> <p>Their research, published in the journal <em>Sedimentary Geology</em>, suggests that drumlins and megaridges are all part of a single family of landforms formed by erosion.&nbsp;</p> <p>鈥淭he new data we were able to obtain shows that these landforms occur on hard rock, which stresses the importance of sculpting below the base of the ice sheet,鈥 says Arbelaez-Moreno.</p> <p>To illustrate the importance of megaridges Eyles points to research being done on the modern Greenland and Antarctica ice sheets. These are slow moving ice sheets but contain faster flowing corridors called 鈥榠ce streams鈥 that are up to tens of kilometres wide, hundreds of kilometres in length and can move as fast as 1 km annually.&nbsp;</p> <p>鈥淭hey鈥檙e essentially arteries moving huge volumes of ice toward the margin of the ice sheet,鈥 explains Eyles. The thinning and retreating of modern ice streams in a warming world has exposed their underlying beds which are seen to be megaridged, and that appears to allow the ice to flow faster across its bed by creating a slippery low-friction surface, he adds.&nbsp;</p> <p>The last Canadian ice sheet (Laurentide) was as much as 3 km thick and behaved in exactly the same way, says Eyles. 鈥淭he transition from drumlins to megaridges may record the final gasp of the ice sheet as it warmed up and began to stream over its bed.鈥&nbsp;</p> <p>Debris that is being dragged under these streams is highly erosive 鈥 鈥渢hink of sandpaper鈥欌 says Sookhan 鈥 and the process sculpts the underlying surface, allowing drumlins to be progressively whittled down into longer and longer megaridges.&nbsp;</p> <p>The data used by the researchers relied on high resolution satellite imagery and new technologies including LiDAR, which uses hundreds of laser beams fired from planes onto the land below. The result is the creation of highly accurate topographic maps even where landscapes are covered by trees or water.&nbsp;</p> <p>鈥淲e still have a lot to learn about how drumlins are formed, but this imaging technique has changed the science by providing a new way of looking at glacial landscapes,鈥 says Sookhan.&nbsp;</p> <p>The megaridges identified by Eyles and his team are particularly common around Peterborough, Ontario at the site of one of the most easily accessible drumlin fields in Canada.&nbsp;</p> <p>鈥淵ou could say drumlins are quintessentially Canadian,鈥 says Eyles. 鈥淭hey do occur in Europe, but are far more common here because almost the entire country was covered by the Laurentide Ice Sheet during the last ice age.鈥</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/2016-03-28-nick-eyles-students.jpg</div> </div> Mon, 28 Mar 2016 11:55:50 +0000 sgupta 7767 at Global collaboration led by 老司机直播 Engineering designs world鈥檚 most efficient catalyst for storing energy /news/global-collaboration-led-u-t-engineering-designs-world%E2%80%99s-most-efficient-catalyst-storing-energy <span class="field field--name-title field--type-string field--label-hidden">Global collaboration led by 老司机直播 Engineering designs world鈥檚 most efficient catalyst for storing 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="2016-03-24T10:17:31-04:00" title="Thursday, March 24, 2016 - 10:17" class="datetime">Thu, 03/24/2016 - 10:17</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">Discovering a better way of storing energy from solar and wind farms is 鈥渙ne of the grand challenges in this field,鈥 Ted Sargent says (photo above by Megan Rosenbloom via flickr/ all other photos and video by Marit Mitchell)</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/marit-mitchell" hreflang="en">Marit Mitchell</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">Marit Mitchell</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/more-news" hreflang="en">More News</a></div> <div class="field__item"><a href="/news/tags/environment" hreflang="en">Environment</a></div> <div class="field__item"><a href="/news/tags/engineering" hreflang="en">Engineering</a></div> <div class="field__item"><a href="/news/tags/collaboration" hreflang="en">Collaboration</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/research" hreflang="en">Research</a></div> <div class="field__item"><a href="/news/tags/global" hreflang="en">Global</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">Saving sunshine for a rainy day by splitting water molecules</div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>We can鈥檛 control when the wind blows and when the sun shines, so finding efficient ways to store energy from alternative sources remains an urgent research problem.</p> <p>Now, a group of researchers led by Professor <strong>Ted Sargent </strong>at the University of Toronto鈥檚 Faculty of Applied Science &amp; Engineering may have a solution inspired by nature.</p> <p>The team has designed the most efficient catalyst for storing energy in chemical form, by splitting water into hydrogen and oxygen, just like plants do during photosynthesis.

Are you happy the federal government has allocated money for these projects?</strong><br> <strong>MS: </strong>The announcement in the budget of $11.9 billion of new money for infrastructure over 5 years represents an initial down payment on the vast need for spending on urban infrastructure across the country.&nbsp;</p> <p>The role of municipalities in providing infrastructure has risen over the years while they collect the smallest share of all tax dollars. So they are really facing a crunch. In the meantime, our infrastructure has become rundown. A lot of it was built in the 鈥50s, 鈥60s and 鈥70s and so now it鈥檚 getting old. It needs to be updated, upgraded and just properly maintained. We鈥檝e missed a generation of investments, both in the capital stock we have now and in expanding to meet the needs of the 21st century economy. This is a key moment to start reinvesting in this next-generation infrastructure.&nbsp;</p> <p>The federal government is identifying high level goals that they want to target for investment, including public transit, affordable housing and in green infrastructure. So those are the key three categories, and then infrastructure in Indigenous communities is also an area where we will see a high level of investment because there鈥檚 need in those areas as well. The federal government has tried to set broad parameters in terms of the target areas for spending. What the municipalities are looking for is more discretion in terms of how they use the money.</p> <p><strong>Can you point to projects that need immediate attention?</strong><br> <strong>MS: </strong>There鈥檚 a critical need for maintenance. These are the unsexy projects, the infrastructure that is not necessarily seen but has been in place and supporting our society and economy for 50 years and now that needs to be upgraded.&nbsp;</p> <p>The first place we鈥檙e going to see investment is in these critical projects, upgrades to things like sewers, water mains, public transit and social housing facilities. For transit in Toronto, for example, the TTC needs a whole new subway signalling system than the one that鈥檚 been in place for a number of decades.&nbsp;</p> <p>It鈥檚 showing its age in terms of how frequently and reliably the trains can be run. &nbsp;For affordable housing, right across the country, public housing has fallen into disrepair. School infrastructure is also in pretty rough shape. And there is an urgent need for investment in water, housing, education and social infrastructure in Indigenous communities.&nbsp;</p> <p>These are all the types of investments that are critically important, but we鈥檝e been deferring for years. The backlogs on all of these infrastructure sectors are in the tens of billions of dollars. The budget announcement of $11.9 billion of new money to be spent on infrastructure over the next 5 years represents an initial funding envelope to make a quick start on the most immediate priorities.&nbsp;</p> <p>It is not nearly enough to meet the vast infrastructure needs of a country the size of Canada, but it鈥檚 a start. Ideally you鈥檙e going to start to see funding for the bigger, new infrastructure projects start to roll out in the coming years.&nbsp;</p> <p><strong>What is your advice to cities like Toronto?</strong><br> <strong>MS:</strong> For operation and maintenance, aim to fill the most pressing needs first. But for bigger newer projects, selection needs to be done based on careful evidence based decision-making. What we find is that when it comes to infrastructure, some of the time decision makers use great evidence to make decisions.&nbsp;</p> <p>And other times, decisions are much more ad hoc, much more politically motivated. Governments need to be consistent in using quality evidence to make sure that they鈥檙e picking the right projects because if they don鈥檛, the risk is that the money is not well spent, it doesn鈥檛 deliver the desired economic, environmental or social benefits, and then the project costs add to the overall debt burden that has to be repaid. Worst of all, governments still have to operate and maintain the infrastructure that鈥檚 being built, even if it hasn鈥檛 delivered much public benefit. That can be a long time drag on government budgets and the economy.</p> <p><strong>How should cities determine the best projects? Look at data? Hold public hearings?<br> MS: </strong>It鈥檚 both. It鈥檚 about engaging with stakeholders and the broader community, which is now a common feature of the decision-making process. This budget was broadly consultative. That鈥檚 a positive step. You have to engage communities.</p> <p>Then, you have to be mixing community input with very careful studies of what the benefits of proposed projects are actually going to be. Infrastructure is a long-term investment. And if you get it wrong, the costs really multiply over time. You have the missed opportunity. You have the debt that you鈥檝e now taken on, and you have the long-term operating and maintenance costs that start to crowd out money for other opportunities. &nbsp; &nbsp;</p> <p>I agree with the sectors that have been targeted for investment&nbsp;<span style="font-size: 12px; line-height: 18px;">鈥&nbsp;</span>transit, affordable housing, green infrastructure, infrastructure in Indigenous communities. Now what I鈥檒l be looking to see is whether the actual specific projects being delivered are selected based on rigorous evidence. We need to make sure we鈥檙e picking the right projects and delivering them well. We need to become much more systematic in how we make decisions to ensure we鈥檙e making the right choices and picking projects that are going to deliver the best long-term benefits.</p> <p><strong>How can data like that generated by 老司机直播-affiliated World Council on City Data (WCCD) help municipalities make decision on which projects to fund?</strong><br> <strong>PM: </strong>We see our data as driving more evidence-based decision-making by leaders, and building transparency in these decisions. The data also informs citizens on performance in service delivery, together with outcomes from that investment.&nbsp;</p> <p>High caliber city data facilitates meaningful dialogue between all levels of government 鈥 a dialogue that is essential following this unprecedented investment in infrastructure. So for example, Toronto is largely considered by many of its inhabitants to be an inefficient city when it comes to transportation. But through WCCD鈥檚 data, we learn that 54 per cent of commuters are using other means to travel to work besides a personal vehicle. We trail Boston at 62 per cent and London at 74 per cent, but we鈥檙e not as bad as Los Angeles, where only 27 per cent of commuters are using alternative means of travel besides their cars.&nbsp;</p> <p>So how can Toronto get to the level of London, for example? Our data, which comes from the first international standard for sustainable cities, which we began developing at 老司机直播 in 2008鈥攃an help city officials and interested citizens easily compare cities to understand what exactly was implemented in London to get to that number. Moreover, the data will allow decision makers at all levels of government to speak to each other about targeting infrastructure investment in areas that need it most.&nbsp;</p> <p><strong>Does this budget signal that Canada has become an urban nation?<br> PM: </strong>Undeniably, Canada is already an urban nation 鈥 with approximately 83 per cent of our population living in cities 鈥 but this budget does signal a strong and clear investment in the future of our cities, not only the inhabitants, but the brick and mortar infrastructure that underpins a functioning city. With aging infrastructure across the country, this investment marks a pivotal shift by the Trudeau government toward preparing this country for a future that will see an increased urban population, ideally supported by smart, sustainable and resilient infrastructure.&nbsp;</p> <p><em><a href="https://www.flickr.com/photos/7119320@N05/23845732690/in/photostream/">Photo above by Sean_Marshall via Flickr&nbsp;</a></em></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/2016-03-24-infrastructure-budget_0.jpg</div> </div> Thu, 24 Mar 2016 09:37:00 +0000 sgupta 7763 at University of Toronto students win with Operation Carpageddon plan /news/operation-carpageddon <span class="field field--name-title field--type-string field--label-hidden">University of Toronto students win with Operation Carpageddon plan</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="2016-03-22T11:01:53-04:00" title="Tuesday, March 22, 2016 - 11:01" class="datetime">Tue, 03/22/2016 - 11:01</time> </span> <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/sayada-nabi" hreflang="en">Sayada Nabi</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">Sayada Nabi</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/more-news" hreflang="en">More News</a></div> <div class="field__item"><a href="/news/tags/biology" hreflang="en">Biology</a></div> <div class="field__item"><a href="/news/tags/utsc" hreflang="en">UTSC</a></div> <div class="field__item"><a href="/news/tags/research" hreflang="en">Research</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>They can jump, fly and eat a third of their body mass per day, but Asian Carp aren鈥檛 superheroes 鈥 the invasive fish species pose an imminent threat to Ontario鈥檚 aquatic biodiversity.</p> <p>Currently, Asian Carp are in American waters, and there are channels they could use to sneak into the Great Lakes and Ontario鈥檚 water system.
