Research Highlights


Study finds aspirin as effective as prescription meds in preventing post‑op clots

A revolutionary new study led by Dr. David Anderson, Dean of the Faculty of Medicine, and Dr. Michael Dunbar, a professor in the Department of Surgery, has determined that Bayer Aspirin is just as effective in preventing blood clots following joint replacement surgeries as rivaroxaban, a costly anti-coagulant commonly used in Canada.

This will result in significant cost-savings for patients, with Bayer Aspirin costing pennies a day, compared to dollars a day for rivaroxaban. It will also create a new standard of care for post-operative care for hip and knee replacement patients not only in Canada, but around the world.

Consumer trust in grocery stores falls since bread price fixing story

A study out of Dalhousie University has discovered that consumer trust in their grocery stores has fallen since allegations emerged that many of the chains worked together to keep bread prices high.

Researchers from the Faculty of Management surveyed 1,641 Canadians across the country for their views on major retail grocery chains, asking people to rate them on a five-point scale on various factors related to their trustworthiness.

Overall, the researchers found that trustworthiness for the sector as a whole declined by 6.31 per cent over the past five-months

Researchers from Dalhousie University help track fishing from space for the first time ever

Humans have been fishing for at least 42,000 years, and for the first time ever, its global footprint can be tracked from space.

Dr. Boris Worm, a Marine Biology Professor in Dalhousie University’s Faculty of Science, and Kristina Boerder, a PhD student from Dalhousie University’s Department of Biology, have partnered with Global Fishing Watch, The University of California, Stanford University, National Geographic Society, SkyTruth, and Google to produce the first ever dataset of global industrial fishing activities by using an unprecedented collection of satellite-sensed automatic identification system (AIS) positions, machine learning, and computing power.

The findings from their research demonstrate the massive global extent of fishing activity, both within countries’ exclusive economic zones, but also on the high seas, in unprecedented resolution.

Dalhousie researcher sheds light on greenhouse gas emissions from fisheries

An innovative study conducted by a researcher from Dalhousie University has compared anthropogenic greenhouse gas (GHG) emissions from fisheries to those from agriculture and livestock production on a national level, and looked at changes in emissions from fisheries over time. The findings indicate that although there was an increase in GHG emissions from fisheries globally over a recent 20-year time period, GHG emissions from most fisheries are lower than from pork, and beef per protein unit produced. 

The full study, which was recently published in Nature Climate Change, will help inform food and climate policy both nationally and internationally, and shed light on the role that fisheries play and opportunities that seafood presents when addressing the environmental cost of global food production systems.

Dr. Peter Tyedmers, a professor in Dalhousie University’s Faculty of Management at the School for Resource and Environmental Studies, is available to discuss this important topic, including why fuel use and resulting GHG emissions from global marine fisheries grew substantially from 1990-2011 without landings increasing much overall, and how emissions associated with seafood from fisheries compare with other sources of animal proteins including beef, pork and chicken.

Tapping into safe and clean water sources  

Most of us turn on the tap without giving it a second thought, but ensuring that everyone has reliable access to a safe and clean water source is vital. Dalhousie University’s Graham Gagnon is addressing the protection of public health, while ensuring that the sustainability of drinking water infrastructure is achieved.

Dr. Gagnon’s research has demonstrated the key benefits of full lead service line replacements, a practice which has been adopted by Halifax Water and is now recommended as a best practice by the American Water Works Association.

Dr. Gagnon has also been working with the Atlantic Policy Congress of First Nations Chiefs (APC) to develop a comprehensive water strategy for the Atlantic region.  A key piece of Dr. Gagnon’s work has been the establishment of the First Nations Clean Water Initiative – Atlantic Region (FNCWI-AR). The FNCWI-AR aims to ensure safe drinking water for First Nations communities not only now, but into the future.

New home, New hope for Syrian child and youth refugees

To date, approximately 11 million people have fled the fear and uncertainty of the Syrian war. Starting over in a new country comes with a unique set of challenges, and researchers from Dalhousie University are conducting world-class research focused on improving the odds of successfully resettling newly arrived refugees.

Dr. Michael Ungar, who is the Canada Research Chair in Child, Family and Community Resilience, recently launched the Child and Youth Refugee Research Coalition (CYRRC). The Coalition, which consists of top researchers, community resettlement partners and government agencies from around the world, is helping communities, service providers, educators and others to research, share and use best practices on interventions to help meet the needs of these newly arrived young people.
