“We’re a long way off from being able to actually bottle antimatter, like in the movie Angels and Demons, but it was important to show that we could trap it for a longer period of time,” said (right), professor in 91��ɫ’s Department of Physics & Astronomy. Menary works on the Antihydrogen Laser Physics Apparatus experiment, dubbed ALPHA, at the (CERN). In November 2010, ALPHA scientists successfully trapped antihydrogen atoms for the first time – but only for a fraction of a second.

“The first time, we trapped [the antihydrogen atoms] for a tenth of a second, which is actually long enough to study them,” Menary said. “But naturally we had people asking, ‘why can you only hold on to them for a tenth of second?’ This experiment demonstrates that we can hold on to them for much longer – in theory, for as long as we want,” he said.

ALPHA physicists, including a core team of scientists from Canadian universities, have been working to trap and study antihydrogen – the antimatter twin of hydrogen – which may help explain the “lost half of the universe.” During the Big Bang, matter and antimatter should have been created in equal amounts; scientists are left with the question, where did all the antimatter go? Researchers are tackling that riddle by taking one of the best-known systems in physics, the hydrogen atom, and investigating whether its antimatter counterpart behaves in exactly the same manner.

Makoto Fujiwara, the study’s lead author, said: “We know we have confined antihydrogen atoms for at least 1,000 seconds. That’s almost as long as one period in hockey! This is potentially a game changer in antimatter research.” Fujiwara is a research scientist at , Canada's national laboratory for particle and nuclear physics, and an adjunct professor at the University of Calgary.

Scientists at CERN were able to make antihydrogen almost a decade ago, but they couldn’t study it; antimatter annihilates when it comes into contact with matter, converting to energy and other particles. ALPHA scientists succeeded by constructing a sophisticated “magnetic bottle” using a state-of-the-art superconducting magnet to suspend the antiatoms away from the walls of the device and keep them isolated long enough to study them.

Canadian researchers are playing leading roles in the antihydrogen detection and data analysis aspects of the project. The collaboration includes scientists from University of Calgary, University of British Columbia, Simon Fraser University and TRIUMF.

The next step for ALPHA is to start performing measurements on trapped antihydrogen; this is due to get underway later this year. The first step is to illuminate the trapped antiatoms with microwaves, to determine if they absorb precisely the same frequencies (or energies) as their matter twins.

ALPHA-Canada and its research is supported by the (NSERC), TRIUMF, (AIF), the and (FQRNT).

The evening saw the presentation of the faculty's inaugural internal research awards to chemistry Professor Dasantila Golemi-Kotra, recipient of the ; biology Professor Chun Peng, recipient of the 2010 Established Researcher Award; and physics Professor (Kumar), the recipient of the 2010 Graduate Mentoring Award.

“These awards were created in 2010 to honour and celebrate the outstanding dedication of our faculty to research and graduate student mentoring. This year's recipients are examples of the excellent talent we have at FSE and we are proud to support our researchers in their fundamental, groundbreaking and innovative research endeavours,” said Janusz Kozinski, dean of the Faculty of Science & Engineering.

Since 2004, Golemi-Kotra has studied the mechanisms of bacterial resistance. Over the course of her research, she has secured significant funding to create a reputable team of researchers. She has established herself as a rising star in the field of biological chemistry. Her research focuses on an emerging and persistent problem of bacterial resistance.

Specifically, Golemi-Kotra's research focuses on the Staphylococcus aureus bacterium, a leading cause of hospital- and community-acquired infections. Extensive use of antibiotics has invariably been followed by the development and spread of resistance in this organism.

Her research aims to elucidate genes involved with the bacteria’s response to antibiotics that specifically target cell wall biosynthesis. Essential to the survival of the bacterium, the cell wall is the organism’s first line of defense against antimicrobial agents. As a result, the cell wall remains an important target in drug development. Golemi-Kotra’s research seeks to identify new factors involved in antibiotic resistance, which will ultimately lead to the design of new antimicrobial agents.

A world expert in the area of ovarian cancer and the molecular basis of complications in pregnancy, biology Professor Chun Peng is the recipient of the 2010 Established Researcher Award. With an impressive track record of awards and publications, a strong research program and team, Peng has made a significant contribution to the understanding of reproductive biology and the role of hormones in human health.

She discovered new proteins and their role in the molecular mechanism of receptor signaling that have led to the discoveries of mis-regulation during placental pathologies. These studies are critical in understanding placental development and are important landmarks in the understanding of the molecular mechanisms of hormonal control in reproduction.

Significantly, her research team has identified a novel mechanism by which chemo-resistance, a major problem in cancer therapy, is developed. Currently, as a result of those discoveries, novel serum markers may be used to predict preeclampsia, a major disorder of human pregnancy and a leading cause of maternal and perinatal morbidity and mortality. Peng's studies focus on ovarian cancer as well as diseases that result from complications of pregnancy. Her research has the potential to not only advance current knowledge but may also lead to potential diagnostic tools and treatment for complications arising from pregnancy.

Kumarakrishnan (Kumar), a professor in the Department of Physics & Astronomy, is this year's recipient of the Excellence in Graduate Mentorship award. A large number of both graduate students have successfully completed their research under his mentorship and moved onto becoming valuable members of the scientific community.

Kumar's  research utilizes the wave nature of cold atoms and the coherent transient response of a collection of laser-cooled atoms to carry out tabletop studies of light matter interactions and precision measurements in atomic physics. The goals of these efforts are to achieve a better understanding of the theoretical foundations of atomic physics as well as to develop cutting-edge techniques and instruments for industrial applications in photonics and optics.
