New research can quickly identify toxins from oil sands and tailing ponds
23-Mar-2022
Waste materials from oil sands extraction, stored in tailings ponds, can pose a risk to the natural habitat and neighbouring communities when they leach into groundwater and surface ecosystems. Until now, the challenge for the oil sands industry is that the proper analysis of toxic waste ...
Findings shed light on factors behind Omicron’s increased transmissibility
24-Jan-2022
Researchers at UBC’s faculty of medicine have conducted the world’s first molecular-level structural analysis of the Omicron variant spike protein. The findings were published in Science. The analysis – done at near atomic resolution using cryo-electron microscopy – reveals how the heavily ...
A statistical model uses a blood biomarker of SARS-CoV-2 to identify infected patients who are most at risk of dying of COVID-19
30-Nov-2021
The amount of a SARS-CoV-2 genetic material—viral RNA—in the blood is a reliable indicator in detecting which patients will die of the disease, a team led by Université de Montréal medical professor Dr. Daniel Kaufmann has found. The finding is published in Science Advances. Kaufmann and his team ...
Catalogue of 166 biomarkers generated through machine learning analysis of long non-coding RNAs
17-Nov-2021
A new batch of prognostic cancer biomarkers have been discovered in an area where few have gone looking before. Researchers have unveiled a catalogue of 166 prognostic biomarkers, generated by analyzing long non-coding RNAs (lncRNAs) – which are understudied in cancer research. Further, one ...
Researchers develop polymer coating that enables low surface tension liquids to be transported over distances 15 times longer than currently possible, without losing any of the liquid
27-Oct-2021
A newly developed coating that allows for certain liquids to move across surfaces without fluid loss could usher in new advances in a range of fields, including medical testing. This new coating— created in theDREAM (Durable Repellent Engineered Advanced Materials) Laboratory, led by University ...
30-Jun-2021
Researchers at McMaster University have developed a promising new cancer immunotherapy that uses cancer-killing cells genetically engineered outside the body to find and destroy malignant tumors. The modified "natural killer" cells can differentiate between cancer cells and healthy cells that are ...
New technique detects minute particles of plastics in snow, rain and even soil
22-Mar-2021
The snow may be melting, but it is leaving pollution behind in the form of micro- and nano-plastics according to a McGill study that was recently published in Environmental Pollution. The pollution is largely due to the relatively soluble plastics found in antifreeze products (polyethylene ...
Scientists can now edit multiple genome fragments at a time
20-Mar-2020
Toronto scientists can now edit multiple sites in the genome at the same time to learn how different DNA stretches co-operate in health and disease. CRISPR-based DNA editing has revolutionized the study of the human genome by allowing precise deletion of any human gene to glean insights into its ...
Scientists demonstrate flaws in protein detection tools, and outline a solution
17-Oct-2019
A new study points to the need for better antibody validation, and outlines a process that other labs can use to make sure the antibodies they work with function properly. Antibodies are used in laboratories and clinics to study proteins, which are the biomolecules that translate information from ...
15-Mar-2019
University of Toronto Engineering researchers have built a set of magnetic 'tweezers' that can position a nano-scale bead inside a human cell in three dimensions with unprecedented precision. The nano-bot has already been used to study the properties of cancer cells, and could point the way ...
