CBC: New telescope at the top of the world to look at universe’s earliest origins
April 19, 2017A new telescope being built in the high desert of Chile will peer further into our universe's origins than any other. The Cerro Chajnantor Atacama Telescope-prime, or CCAT-p for short, is six metres in diameter and there are more than 40 Canadian researchers working on the high-powered instrument. Scott Chapman, an astrophysics professor at Dalhousie University, said the telescope has an unprecedented number of detectors to catch far-infrared wavelengths of light invisible to the naked eye. Those wavelengths of light could give scientists a glimpse into the early formation of our universe following the Big Bang nearly 14 billion years ago, as well as the formation of our own Milky Way galaxy and the nature of dark matter. "It ends the dark ages of the universe when these first objects of the universe turn on, first galaxies start to form and the stars emit their light," Chapman said. "This is an untapped earliest epoch in the universe which this telescope is well designed to figure out how that happened." Read the full article here.
St. Catharine’s Standard: Brock research finding steps to take in stalking cancer
April 19, 2017Research at Brock University recently uncovered a link between a common herb and the reduction of lung cancer cell growth. A study into rosemary began with Evangelina Tsiani’s interest in polyphenols — chemical compounds found in plants we eat. Tsiani, an associate professor in Brock’s department of health sciences, wanted to know more about the polyphenols, sometimes called antioxidants, found in the herb. Polyphenols contain tiny nutrients believed to help to prevent diabetes, cancer, heart disease and other conditions. “We have some evidence that rosemary extract stops the growth of cancer cells,” Tsiani said. “The question is, how is this done? What is the mechanism of action to inhibit cancer cell proliferation?” Working with graduate student Jessy Moore and colleagues from several other Brock departments, Tsiani set out to see if and how rosemary extract stops the growth of cancer cells.

YFile: New research on mini strokes points to earlier diagnosis, prevention
April 19, 2017York psychology Professor Gary Turner realizes the perks of working at a global centre of excellence in cognitive neuroscience and neurorehabilitation – primarily, the opportunities to work in a leadership position with other high-profile Canadian researchers. He recently undertook a systematic review, which collects and analyzes multiple research studies or papers, with colleagues from the University of Toronto, the Rotman Research Institute at Baycrest, and Sunnybrook Health Sciences Centre. Turner has been supervising lead author and graduate student, Ayan Dey. What this team learned about mini (or silent) strokes could lead to improved prevention through policy uptake and earlier diagnoses combined with appropriate treatment plans. Through this research, funded by the Canadian Institutes of Health Research (CIHR) and the Heart and Stroke Foundation Canadian Partnership for Stroke Recovery, Turner sees a very real potential for improved health outcomes of Ontarians.

National Observer: How to grow veggies at the edge of the Arctic
April 4, 2017Fresh, locally grown kale, at the edge of the Arctic Circle? A Ryerson University student project is proving it’s possible to grow vegetables in a part of Canada where almost nothing green can survive. Produce is usually shipped to Canada's northern communities by air, truck or barge, depending on the season. A greenhouse built by the Growing North project enabled the Inuit community of Naujaat, Nunavut, for the first time, to produce their own fresh produce grown right at home at the edge of the Arctic Circle. It was enough for half of the 1,000-person community to eat vegetables every day. Growing North just won a $250,000 prize from the Google Impact Challenge, and co-founder Stefany Nieto said in an interview that they’re now planning to build two more greenhouses in a second Nunavut community. Communities up north desperately need affordable produce, she told National Observer. “Here, we always have to force kids to have their vegetables. When we go up north, it’s ‘Can I have carrots? Can I make kale chips?’” said Nieto, who started Growing North with fellow Ryerson student Ben Canning in Toronto in 2014. She said they took on the project after learning about the high levels of food insecurity facing residents of the far north. Read the full article here.
