Fish scales serve as new model for protective armour

Imagine a hockey player preparing himself for a game and donning his socks, skates… and fish scale shoulder pads. This is not as outlandish as it seems—researchers are using fish scales as the model for a new wave of stronger protective armour.

Since 2006, Francois Barthelat—associate professor of mechanical engineering at McGill and associate member of McGill Biomedical Engineering—has worked on synthesizing a new armour with incredible strength, flexibility, and lightness, modeled after the scale patterns on fish.

He first got the idea from the tough scales of striped bass, which are stronger than tooth enamel (the hardest material in the human body). Though the scales themselves are made of collagen and hydroxylapatite, which are not tough materials, the special structure allows the scales to withstand incredible pressure.

The scale material structure is comprised of layers that  follow an alternating perpendicular pattern, like jenga blocks. The layers alternate between collagen, and a hard, mineralized material.

Barthelat has demonstrated the scales’ ability to provide significant protection for the fish. As opposed to a solid bony structure, they are thin and light, but still can deflect a sharp strike.

“You get something that’s like a full package for [protection] … It resists puncture and is highly flexible, light and thin,” he said.

If the hard scale surface does break, it breaks in a clean cross pattern that dissipates energy, with the soft cross-ply collagen absorbing the rest of the impact. Even a piercing predator’s tooth would struggle to rip through a thin layer of scales.

Barthelat modeled a new protective material after this structure. Using pressure tests, he compared his armour with polycarbonate, the current standard material in squash goggles and hockey gear. The tests proved his material was able to withstand 50 per cent more pressure than the best hockey and squash equipment.

The potential for novel designs inspired by nature is almost limitless; the challenge is seeing the engineering applications of familiar materials. “Fish scales are something people see everyday.”

“I think one of the most exciting things is that we […] do new things that nobody else has tried. I think it’s a great area to work in because there are so many materials to work with,” Barthelat said. “There are hundreds of other materials around us to work with that nobody has tried before.”

Trudeau’s leadership bid will bring youth issues to centre stage

Justin Trudeau’s Liberal leadership bid has dominated coverage of Canadian politics all week. His recent announcement has been met with everything from praise to outright disapproval. While some have extolled his idealism, others have criticised his lack of specific policy points. Many have warned him to clearly separate himself from the legacy of his father, or risk running a stylized campaign based on little substance.  Supporters are pleased by his success with certain segments of the electorate, especially the traditionally elusive young voting block, with whom he is immensely popular. What Trudeau could do for young Canadians, though, extends far beyond courting their vote. For the first time in many years, we have a candidate on the national stage who is not most known for his economic prowess or environmental advocacy, but for his commitment to education and youth issues.

It’s still early in the leadership race—the convention is not until next April. While we are in no position to endorse a specific candidate, we find Trudeau’s background brings a welcome change to federal politics, which rarely feature education or youth involvement as key issues.

Trudeau has been a supporter of post-secondary students and young Canadians long before his foray into national politics. Unlike certain provincial leaders closer to home, whose commitment to students and their tuition struggle appear to have been politically motivated, Trudeau has not only stood on the side of students when it was convenient, but has devoted much of his adult life to that cause. After the Liberals’ defeat in 2006, he chaired a task force to learn how the party could best address the issues that mattered most to young people. As a Member of Parliament, he has been the party’s Critic for Youth, Citizenship and Immigration since 2010, and was Critic for Multiculturalism and Youth in 2009.

An educator himself—he holds a Bachelor of Education and taught high school in British Columbia for five years—Trudeau has always endeavoured to include the youth voice in decisions about Canada’s future. In November 2009, he brought forward a private member’s bill—the first of that session of Parliament—calling for a “national voluntary service policy for young people.”

Before he became a Member of Parliament, Trudeau was chair of Katimavik, Canada’s National Youth Service program. The popular volunteer experience was axed by the Harper government in the 2012 budget. Many alumni of the six-month program—which builds leadership, encourages volunteerism, and educates about different cultural identities—refer to it as a life-changing experience. In light of a dizzying array of cuts to social programs, a candidate who brings a discussion of the importance of youth programs to the forefront is beyond valuable.

A young caller on CBC’s radio talk show, Cross Country Checkup, noted that: “Many politicians think about young people as the leaders of tomorrow, but Trudeau speaks to us like we’re the leaders of today.”

That distinction couldn’t be more important for young Canadians. Regardless of how Trudeau fares in the leadership contest, his candidacy will bring the importance of education to centre stage in a political climate currently dominated by the economy.  At the same time, his persona, youthfulness, and popularity among voters under 30 will spur youth involvement in politics.  Both are, undeniably, good things for the future of our country.

Re: “Indigenous studies program approval announced at Council” (Oct. 2)

I was somewhat surprised to read in your edition of Oct. 2nd that I had  “approved the creation of a new Indigenous Studies Program within the Faculty of Arts,” since I do not have the authority to approve programs. However, I have on many occasions, over several years (including this year) indicated that I support the establishment of such a program and that I look forward to the Faculty’s receiving a concrete proposal through the normal program approval process.  I am pleased to know that a group of students is working on such a proposal, and I look forward to collaborating with them to design a program that will enrich the Faculty’s interdisciplinary offerings.

Time to wipe the dust off of community education

If you’ve been to campus recently, you’ve probably come across Community Engagement Day promotions, or maybe you even saw the tent on the Lower Field on October 5th. Maybe you even bothered to look into it; heck, you could have even registered to participate.

So what did Community Engagement Day (CED) mean for the students involved, for the community organizations, for McGill, as an institution? What does it mean—for a school so focused on academics—to have an entire day dedicated to the importance of the Community Engagement? Was it simply a passive way to fulfill McGill’s social responsibility and community engagement agenda? I like to think that it was more than a formality. I like to think that McGill has finally begun to understand that in today’s society, integration with community is just as important as academic achievements, as entrepreneurial success, as scientific progress—because without community, all those things are rendered meaningless.

A ‘well-rounded’ individual is no longer just a grad school requirement—it has become a very basic expectation, and community service is perhaps the easiest and the most rewarding way to fulfill it.

I’d like to think that there is a culture shift at McGill, whereby students are taught to appreciate social sustainability, and are encouraged to be proactive in their education. I’d like to think that a few hours at a local shelter, or a day spent cleaning up one’s neighbourhood can be seen to be just as resourceful as a blackboard or a projector screen at the front of a classroom. Moreover, I’d hope that this alternative—community education—could receive even a fraction of the recognition attributed to formal education.

I know I didn’t come to university expecting to learn everything from behind the desk. I came to learn by doing. Community Engagement Day has allowed me to do just that, in more engaging and rewarding ways than this letter can express. If you didn’t take part in CED, the world didn’t end. But it didn’t get any better either.  So get involved, change your views, and allow yourself to accept challenges and risks that will enrich your university experience. Stop fooling yourself into thinking these things don’t matter, or you’ll break your leg kicking yourself later.

Trudeau’s idealism is not what the Liberals need right now

Last Tuesday, Justin Trudeau announced the launch of his much-anticipated Liberal leadership campaign. The speech appealed to a wider base, reflecting the party’s need to re-establish itself in the centre of the Canadian political spectrum, staving off a rapidly expanding NDP and the ideologically-grounded Conservative party. In order to win the leadership of the party, the 40-year-old MP needs to establish himself as a serious candidate—beyond his popularity, and distinct from his father’s legacy. Trudeau needs to demonstrate that he is fully capable of recovering significant ground for the Liberals without letting his idealism eclipse more concrete policy points.

“The key to Canadian unity is the shared sense of purpose so hard to define but so deeply felt, the sense that we are all in this together,” Trudeau said at the rally. “That when Albertans do well, it creates opportunities for Quebeckers. That when Quebeckers create and innovate, it echoes across the country and around the world.  That whether you’re in St. Boniface or St. John’s, Mississauga or Surrey, we have common struggles and common dreams.”

Trudeau is asking Canadians to allow him to lead the Liberal Party through much needed, balanced reform. It’s unclear that the yet unproven candidate can do so with unsubstantive rhetoric.

Trudeau is an accessible candidate. He can appeal directly to a younger generation of voters, has an ambitious vision of a unified Canada, and this past Tuesday, proved he could land lines in both English and French.  While these are all virtuous qualities in an energetic politician, it is all for naught if his aspirations cannot yet be carried out by the Liberal party. Though the scope of Trudeau’s objectives for the country are impressive, I am sceptical about his ability to keep up with big-picture claims.

After his party’s loss of 43 seats last May, Trudeau agrees that Liberals needs more than just a change in leadership. In what is now a much narrower political environment, Trudeau—if he wins the leadership race—should seek a more measured, policy-based, and structured recovery. With the NDP in position as a viable opposition, the Liberal Party cannot afford to disappoint a new wave of Canadians. Beyond the leadership race, idealistic promises and a lack of experience won’t benefit Trudeau nor the Liberal Party.

Are there benefits to Trudeau’s bold rhetoric? Sure, broad ideas for the role of the middle class, Indigenous peoples, Quebeckers, and young Canadians have the potential to hugely shift the political discussion and the potential to invoke real and positive change; however, rhetoric without clear policy could hurt both the candidate and his own party. Expectations are high for Trudeau. He needs to escape his own celebrity, and demonstrate he can effectively lead his party back to a position where it can contend for control of parliament. The Liberal Party itself is in rough shape and has to compete within a tighter federal race where idealistic assertions will not win seats, and are in need of a more realistic platform.

At his launch event, Trudeau was asking for our trust, or rather, the opportunity to earn our trust. Tempting as it is to believe the young, articulate MP from Papineau can enact his vision of a revived Liberal Party and the induction of a unified Canada, the capacities of the recovering Liberal Party trying to wedge their way back into the centre of a more crowded playing field are cause for wariness. It’s not Trudeau’s lack of ambition that concerns me—it’s all political.

Journey or the destination?

Earlier this year, India’s most well-known newspaper, The Times of India, was found to have recycled a three-year-old full page cover story word-for-word as a paid-for advertisement. There has been an alarming regularity with which incidents of gross misconduct have come to light: for example, over 100 Harvard students cheated on an exam last academic year. Closer to home, Margaret Wente of the Globe and Mail admitted to running excerpts written by others in a July 2009 column, passing them off as her own. Most recently, the Harvard Crimson scrutinized Paul Krugman’s citation standards in one of his NYT op-eds.

Each of these cases (barring Dr. Krugman, of course—journalistic citations demand integrity but definitely offer some latitude) presents interesting questions to ponder. Can money cloud the judgment of a newspaper enough for it to sell its masthead to advertisers? Does the promise of getting a good grade on a final motivate an entire class to cheat? Would the prospect of publishing a spectacular piece drive a columnist to sample other’s thoughts and opinions without credit? Wente is certainly not an exception in this case. These questions are eloquently summed up by American philosopher Martha Nussbaum in her The Fragility of Goodness. This philosophical treatise is Nussbaum’s authoritative view on notions of tragedy and ethics. By analyzing ethical dilemmas, Nussbaum puts forward a pointed question: Why should anyone do the right thing when there are no particularly striking incentives for good behaviour?

The motivation for such acts of plagiarism largely stem from mismanaged time. During the years we spend at McGill, there’s always room for a lapse or two—under the brutal force of a looming deadline, all standards of ethics and originality can crumble. When immediate focus is placed entirely on submitting an assignment, acing a final, or turning in a report, the final results—grades—take precedence. Acquisition of knowledge and expertise in a field feel like utopian ideals in a system of education that seemingly acts against you. The joy and goal of learning seem mundane as we don roles of assignment-completing, number-crunching machines. The incentives are not apparent; the options tempting, even corrupting. In the viral age, it is much easier to give in, and it is just as easy to get caught.

[pullquote]Why should anyone do the right thing when there are no particularly striking incentives for good behaviour?[/pullquote]

Finding the right incentives lies at the core of reform. All is not right with the way higher education functions. Most institutions deal with plagiarism by penalizing misbehaviour. The failure to acknowledge and reward good deeds can counteract the effects of these supposed bulwarks that prevent damage. For instance, many consumers at the grocery store check-out line continue to spring the few additional cents for a plastic bag without thinking, and wasteful behaviour progresses in an infinite loop. The ideal solution to this issue is to charge more and provide a cloth bag. Any sensible consumer would eventually bring his or her own cloth bag (likely purchased at a check-out line at some point). This sort of positive penalization promotes good behaviour.

The solution to academic dishonesty is a similar one. Instead of handing out an identical problem-set to a class, students should be allowed to select from a pool of challenging questions. Additionally, the weighting of assignments towards the final grade can be reduced to a bare minimum, assuming that most of the cheating happens on assignments. If such a system were replicated in educational establishments today, there’s some hope for the preservation of the ideals in a real university education.

On campus politics

With AUS elections underway (voting period is from October 4th-10th), debate on the importance of student politics is particularly potent. The recent discussion on student politics in the Tribune has suggested two things: first, there are core reasons we should be politically active on campus; second, political activism helps students identify with those reasons, providing an impetus for these students to get involved.

However, students should not be expected to come to McGill with an understanding of their role in McGill civil society, nor should they be expected to understand the political context in which they entered McGill. The lack of involvement in student politics suggests a lack of grassroots engagement with students. Any civil society’s reach is dependent on its ability to demonstrate its cause to be important.

Sometimes, students are simply unaware of the issues on which they are able to take a stance. The AUS and other faculty associations should focus on how to illustrate the importance of political involvement on campus. It is a long-term goal, and perhaps waiting to reap its benefit could seem too distant. However,  without an effective ability to elect individuals who can identify and communicate the issues that would mobilize students to vote, it would be pointless to run a political society in the first place. Reliable and effective dissemination of information regarding substantial student issues have become underrated. Modes of communication, like listservs, have arguably proven themselves to be less user-friendly than they should be. As a whole, spreading awareness has become far too undervalued to make any meaningful progress.

[pullquote]The lack of involvement in student politics suggests a lack of grassroots engagement with students.[/pullquote]

Political leadership, especially in a student society, necessitates striking a balance between taking one’s own initiative and accommodating people’s needs. Unfortunately, to compel engagement in civil society (voting), student leaders tend to inadvertently become too representative, and this has upset the balance needed in student leadership. Taking too much individual initiative breeds stagnation, in part because students are unaware of many issues. As a result, candidates end up failing to voice issues that resonate with them the most, all the while making empty promises of “this is how I would deal with your hypothetical issues.” This, once again, ultimately leads to a failure in progress through their own initiative, as well as the hypothetical initiative of students.

The question thus lies in whether McGill student associations can make their automatic memberships serve a clearly defined purpose. The problem with the lack of student involvement in campus politics alludes to a structural issue, and begs the question of whether there is a need to manipulate the structure of campus civil society to necessitate student government as an entity in the first place. There is a need for more encouragement to engage in the democratic process.

Rowling’s latest is vacant of magic

Five years after Harry Potter and the Deathly Hallows, J.K. Rowling has finally released The Casual Vacancy, a novel aimed at adults. Set in the town of Pagford, the plot follows the town’s inhabitants in the aftermath of the death of Barry Fairbrother, renowned member of the town, formerly cositting on the city council and heavily influencing the town’s adolescents. His death creates what is known as a ‘casual vacancy’ on the council board, and the rest of the book deals with the ensuing upheaval.

Fans may be let down by Rowling’s The Casual Vacancy. The writing is so obviously Rowling’s that it is almost painful to be reading about Barry Fairbrother instead of Harry Potter. Her penchant for making the quotidien wonderfully descriptive forever cemented the world of Hogwarts in the minds of a generation, but falls flat in the little town of Pagford.

The problem is that this novel is bland. What it lacks is magic—and not, necessarily, in the literal sense. Would the entire story be made better if each character carried a wand and attended Hogwarts? Yes. But that wasn’t Rowling’s goal. She wanted to write an adult novel exploring the teeming underbelly of town life: the antagonism of close quarters, rampant intolerance and racism, sexual frustration, and the general unease that hides behind the pretty façade of an old-fashioned English town. She does just that, but it lacks the flair of her best-selling series. The story itself has promise, and her characters are well-written, but they lack the appeal, emotional gravitas, and depth that we have come to expect from her.

Even though this is an adult book, the shining characters are the young adults of the town, making it clear that Rowling’s forte is truly grasping adolescence, a stage often misrepresented, stereotyped, and trivialized by adult writers. While the adult characters are stodgy, hypocritical, and oddly reminiscent of the Dursleys, the younger characters are engaging—despite being a far cry from the beloved heroes of Potter. Their drug abuse, self-harm, swearing, and casual sex set them up to be completely misunderstood by the adults of Pagford; but their actions throughout the novel reveal them to be much more sophisticated and morally sound than the petty, unsympathetic, close-minded folk of Pagford.

This book progresses as expected, but reading it certainly wasn’t boring—rather, the melodrama of the final act leaves the bitter taste of disappointment. It’s a well-enough written novel, with some biting social satire and an interesting perspective on small English towns, but it is also dark and bleak, without the hope and fantasy of Harry Potter. Perhaps it is childish to expect a neat happy conclusion that restores our faith in humanity, and perhaps it was the best thing J.K. Rowling could do to distance herself from her previous characters, but one cannot help but hope that she returns soon to her magical roots.

Researchers unmask genetic nature of ovarian cancer

Ovarian cancer is the fifth-most diagnosed cancer among Canadian women, accounting for four per cent of all new cases. Tragically, 75 per cent of these new cases prove terminal within five years of their diagnosis. Although it is often compared to breast cancer, ovarian cancer is, in fact, more deadly, because detection usually occurs at a relatively advanced stage.

“Breast cancer patients die—not because of the cancer itself, but because of the migration of the cancer cell, while ovarian cancer patients die because it cannot be controlled,” Dr. Patricia N. Tonin, cancer researcher at the Research Institute of the McGill University Health Centre (RI-MUHC) and associate professor in McGill’s department of medicine, said of the disease.

Recognized as the most lethal gynecological cancer, ovarian cancer differs from other forms in its aggressive characteristics and the general lack of clinical and technological advancement in treatment techniques.

While 95 per cent of ovarian cancer cases can be labeled as benign, they are treated in the same way as the malignant cases—with extensive rounds of chemotherapy and cytoreductive procedures.

However, a recent study conducted by the RI-MUHC—in collaboration with the Lady Davis Institute of the Jewish General Hospital and the University of Montreal Hospital Research Centre—has discovered two distinctly different genetic patterns that will not only shed light on the biological make-up of the disease, but may also revolutionize treatment plans, which currently lack customization, by focusing separately on each of these two cases.

According to Dr. Tonin, who led the study, the underlying mechanism causing ovarian cancer is the mutated form of gene TP53, which produces an abnormal, mutant protein p53. When the protein is functioning normally, it “maintains the integrity of the genome,” by detecting massive reorganizations, which is a signal of possible mistakes conducive to the advent of cancer. The protein either decides “this is such a mess; we are going to kill the cell [or] we can fix this mistake,” Dr. Tonin said.

In over 90 per cent of high-grade serous ovarian carcinomas (HGSCs), a common form of ovarian cancer, the gene that has been mutated is typically responsible for sensing problems with the organization of the genome. The mutant gene instead blocks any opportunity to dispose of the troublesome cells.

The consequences of ovarian cancer vary dramatically across cases, based on the biology of the protein. A cell with mutated TP53 either may or may not produce a mutant p53 protein, and these two outcomes are directly linked to the survival rate of ovarian cancer; the former results in longer survival times and delays in cancer cell reoccurrence than the latter.  This is a groundbreaking discovery because it is the first to uncover the biological difference between the two genetic patterns of ovarian cancer.

Dr. Tonin’s research paves the way for future studies into the pharmaceutical solutions to cancer. Scientists will continue working to find medications that are specifically targeted at each individual pattern, so as to reduce the invasiveness of future clinical procedures, and improve the overall outcome of treatment plans.

“Our next step,” Dr. Tonin said, “is to replicate our findings with publicly available datasets, separate the samples into two groups, and see if the patients actually survive longer, and also to generate more sophisticated data points to identify the genes involved in a more specific way.”

 Cytoreductive: reducing the number of cells, as in surgery for a tumor.

The imperfection–and triumph—of Holocaust films

Writing, directing, and producing a movie is a difficult undertaking. Films take on the enormous task of representing the world—all its sensations and nuances, beauties and horrors—in a very limited medium. Considering the added difficulty of portraying an event as appalling and horrific as the Holocaust,  an accurate depiction through film seems nearly impossible. In fact, it is impossible. And yet, film is still the best way to keep the memory of the Holocaust alive. Relatively few people will read textbooks, listen to interviews, take seminars, or go to museums, but everyone watches movies. Cinema, though imperfect, is the optimal form of media to connect people to the Holocaust.

This month, Cinema du Parc makes an honourable attempt to embrace as many Holocaust narratives as possible in their showcase, About the Holocaust: A selection of rare films. The movies range from the very old to the very recent, from documentaries to Hollywood blockbusters. Though no film will ever be able to portray the Holocaust with complete accuracy, this wide assortment of attempts generates a relatively holistic interpretation of the Holocaust. Acknowledging that it cannot be condensed into one narrative, one victim, or one emotion, Cinema du Parc hopes that presenting all these films collectively will be the best attempt.

The short French documentary, Night and Fog, asks “what hope do we have of truly capturing this reality?” The narrator states that “words are insufficient,” but continues nonetheless, attempting to find the language that can even begin to describe the Holocaust. Like many other films of this genre, Night and Fog is a paradox that acknowledges the impossibility and hopelessness of relaying the Holocaust through film, but tries anyway. The struggle to achieve the impossible is the most important thing we can do as a post-WWII generation.

So if Holocaust films are inaccurate, then why make them? The films do not exist just to make us cry, or to make sure we never forget—the responsibility of Holocaust movies is to trigger our innermost sense of humanity. We must ask ourselves, as The Reader so bluntly puts it, “What would you have done?” Thanks to Cinema du Parc’s wide collection of films, there is no shortage of situations where we can, and must, ask ourselves this question.

Each movie shows different individuals in different circumstances, and they all have to make moral and ethical choices that define them as human beings. In Sophie’s Choice, Meryl Streep’s character begs, “don’t make me choose”—in the kind of world we want to live in, we shouldn’t have to make the kinds of choices that she made. Yet, movies force us to imagine just that kind of world. Cinema thrusts our latent, most basic levels of humanity to the surface; it encourages us to evaluate ourselves through the perspectives of various characters, so that we will be prepared to make the right choices.

Experiencing past attrocities through cinema makes us strive to be more humane in the present. In this way, we can reassure ourselves that we—as individuals and as a contemporary society—will never let such events happen in the future.

Holocaust films will always fail in the sense that the topic simply cannot be perfectly translated to film. Whether or not they succeed depends on what we learn from them—not about the Holocaust, but about ourselves. Because, as The Reader asks, “if people like you don’t learn from what happened to people like me, then what the hell is the point of anything?”
