Children in conflict
Split-second decisions soldiers make in the fog of war have long-term consequences on their mental and moral well-being long after the soldier returns home. But little is known about this phenomenon, and no formal research has yet been undertaken to study the issue from the perspective of those who interact with children in armed conflict. It is this motivation that led Dal鈥檚 Dallaire Institute for Children, Peace, and Security to begin a study in 2020, which has just been expanded through funding from Veterans Affairs Canada. The research project will be the first of its kind to explore the connections between morally injurious events and the recruitment and use of children as soldiers.

Stronger, lighter, tougher
As a kid, Karan Chowdhry liked to ask, 鈥淲hy?鈥� That passion for understanding things has translated into developing technology that can solve real-world problems. Chowdhry is one of the founders of 3D BioFibR, a Dal spin-out company focused on the production of biofibre that has the type of quality and scale that is not achievable with current manufacturing methods. Some of the products 3D BioFibR has created include CollaFibRTM Tendon, which can serve as an excellent artificial tendon in both tissue models and鈥痬edical applications; and SpidrFibRTM, which has exceptional mechanical properties, and shows great potential for applications in the green textile industry and in bio-composite development for aerospace engineering and defence.

Investigators track the vax
Members of the public were asked to play an important role in completing the largest study of vaccine safety in Canadian history. Jennifer Isenor, a researcher in the Faculty of Health, is a regional investigator on the study, which is examining adverse reactions to COVID-19 vaccines. The project is being coordinated by investigators with the Canadian National Vaccine Safety (CANVAS) Network, and may be reassuring in providing additional data on the safety of the vaccines and helping those who are vaccine hesitant decide to get the shot. Investigators are looking to enrol 400,000 participants per vaccine across the county, in B.C., Yukon, Alberta, Ontario, Quebec, Nova Scotia and P.E.I. They also aim to register a control group of approximately 50,000 unvaccinated participants.

Building a better battery
Two outstanding scientists have become research chairs at AV俱乐部 and have joined the university鈥檚 exclusive partnership with Tesla. Chongyin Yang and Michael Metzger are both working very closely with Jeff Dahn, Canada Research Chair in Materials for Advanced Batteries. Dr. Yang鈥檚 research group will focus on developing high performance materials for advanced lithium-ion batteries. Dr.鈥疢etzger鈥檚 group will focus on developing novel methods to study the performance and lifetime of advanced lithium-ion batteries, lithium metal batteries and desalination batteries. Work officially began with Tesla in 2016, and the partnership has been renewed until at least 2026.

One-shot wonder
One of the tools being used to fight COVID-19 has Dal roots. Mathai Mammen (BSc鈥�89) and his global team of more than 13,000 scientists are responsible for the research and development of the single-shot Janssen (Johnson & Johnson) vaccine. 鈥淲ithin days of learning the sequence of the SARS CoV-2 virus, our team began work on a number of versions of that sequence, so that the researchers could鈥� pick from those versions the best version that would cause the strongest multi-pronged immune response if it were made into a vaccine,鈥� says Dr.鈥疢ammen. 鈥淲e were able to pick something that you were just able to give in a single shot, as opposed to multiple shots in order to create a robust and protective immune response against the virus,鈥� says Dr.鈥疢ammen.

Major milestone
Researchers from around the world have developed a plan to safeguard more than 80 per cent of global habitats for endangered marine species, while also increasing fisheries catches and curbing carbon emissions by up to one billion tonnes per year. The study, co-authored by AV俱乐部 Biology professor Boris鈥疻orm, is a major milestone in achieving meaningful ocean protection of 30 per cent of marine area by 2030. The 26 authors also quantified for the first time the potential release of carbon into the ocean from bottom trawling, finding that the fishing practise releases hundreds of millions of tons of carbon into the ocean every year.
