New technique can quickly detect fentanyl and other opioids
Testing method can analyze blood samples twice as quickly as other techniques University of Waterloo researchers have developed a new blood testing method that can detect potent opioids much faster than traditional approaches and potentially save lives. The method, the latest effort by Waterloo researchers and entrepreneurs to lead health innovation in Canada, can simultaneously analyze 96 blood samples that could contain opioids such as fentanyl in under three minutes - twice as quickly as other techniques.

Researchers are using RNA in a new approach to fight HIV
Society learned about the value of mRNA during the COVID-19 pandemic when we saw scientists and medical professionals harness its power to deliver a vaccine for the virus within a year. Now, University of Waterloo pharmacy associate professor Emmanuel Ho has developed a novel nanomedicine loaded with genetic material called small interfering RNAs (siRNA) to fight human immunodeficiency virus (HIV) using gene therapy.

Stress is higher for women in long-term relationships
Stress is higher for women in long-term relationships
In long-time couples, women are more affected than men by the cumulative effects of stress as measured by the physiological indicator known as allostatic load, a U.S.-Canada study suggests. The chronic stress that builds up over decades in a relationship affects each member of the couple differently; in heterosexual couples, the woman is more likely to display negative physiological markers than her spouse.

Can smells improve your athletic performance?
Yes, they can, says Mathieu Cournoyer, a master's student in human kinetics who's done a review of 19 studies on the topic. Did you know that the scent of peppermint can make you run faster? That a whiff of ammonia will make you do a few more push-ups than usual? Or that the fragrance of jasmine can improve your bowling score? Those and other findings were made by Mathieu Cournoyer, a master's student in UdeM's School of Kinesiology and Human Kinetics, who reviewed 19 studies on the effect of olfactory stimulation on physical activity.

A 'heart on a chip'
A ’heart on a chip’
Developed in Montreal, the device - a 3D-bioprinted, miniaturized chip - promises to advance understanding of cardiovascular disease and aid in the development of new precision treatments. Scientists at the Centre de recherche Azrieli du CHU Sainte-Justine, affiliated with Université de Montreal, have developed a device that accurately simulates the electrical activity, mechanics and physiology of a human heart.

New understanding of avian eggshell attachment
Athletes often suffer injuries to ligaments in their knee s, particularly to the anterior cruciate ligament or ACL. W hile surgery to replace these torn ligaments is becoming increasingly common around the world it often needs to be re peated. That's because it has proved challenging to anchor fibrous, soft and wet ligament grafting material into hard bone.

Can hydrogels help mend a broken heart?
Researchers design gel from wood pulp to heal damaged heart tissue and improve cancer treatments You can mend a broken heart this Valentine's Day now that researchers invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments. University of Waterloo chemical engineering researcher Dr. Elisabeth Prince teamed up with researchers from the University of Toronto and Duke University to design the synthetic material made using cellulose nanocrystals, which are derived from wood pulp.

A new era in wound care
Hydrogels are engineered materials, which absorb and retain water and are currently used in various medical treatments, including dressing wounds. The problem with current hydrogels is that they adhere indiscriminately to all surfaces, which means that wound dressing can potentially damage delicate tissue as it is healing.

Making AI a partner in neuroscientific discovery
New paper argues that Large Language Models can reveal breakthroughs humans alone cannot The past year has seen major advances in Large Language Models (LLMs) such as ChatGPT. The ability of these models to interpret and produce human text sources (and other sequence data) has implications for people in many areas of human activity.

Results for: National study seeks to close research gaps for kids with chronic gastrointestinal inflammation
Canada has among the highest rates of Inflammatory bowel disease (IBD) in the world, averaging a new IBD diagnosis every 48 minutes. The onset of paediatric IBD was found in more than nine children per 100,000 in 2023 according to the Crohn's and Colitis Canada 2023 Impact Report. Dr. Jennifer deBruyn, MD, is the co-chair of  the Canadian Children Inflammatory Bowel Disease Network (CIDsCaNN) and first author of a new study comparing two advanced treatment options for paediatric Crohn's disease, a type of IBD in children that she says needs further research.

Results for: UCalgary researcher develops new tool to diagnose genetic mutations
Dr. Pierre Billon, PhD, was frustrated with the time it took to get genetic analysis done at specialized private labs. Results of DNA samples that he needed for his research weren't available for weeks and sometimes months. Outsourcing to genome facilities was also expensive. Billon was convinced there was another approach that could provide results faster and in a more cost-effective way.

New eye drug may someday help diabetic patients
Scientists have developed an experimental medication called UBX1325, or foselutoclax, that shows promise in treating macular edema. Diabetes can lead to eye problems, and a common one is diabetic macular edema (DME), causing vision loss. Now a study published in Nature Medicine suggest a new experimental drug could someday help make treatment of DME more successful and longer-lasting.
