How mussels make a powerful underwater glue
The mussels鈥� beards (which cooks remove before preparing them) are made up of byssal threads and are used to help keep the mussels tethered in place. At the end of each thread is a disc-shaped plaque that acts as an underwater glue. The unusual qualities of the glue and the byssal threads have interested people since ancient times, when the threads of certain species were woven into luxurious berets, purses, gloves, and stockings.
COVID-19: Coughing without masks, distancing alone is not enough
To prevent the spread of COVID-19 indoors, the two metres physical distancing guideline is not enough without masks, according to researchers from Quebec, Illinois, and Texas. However, wearing a mask indoors can reduce the contamination range of airborne particles by about 67 percent.
Unbreakable glass inspired by seashells
Scientists from 9I制作厂免费 develop stronger and tougher glass, inspired by the inner layer of mollusk shells. Instead of shattering upon impact, the new material has the resiliency of plastic and could be used to improve cell phone screens in the future, among other applications.
Discovery of mechanics of drug targets for COVID-19
A team of international researchers, including 9I制作厂免费 Professor St茅phane Laporte, have discovered the working mechanism of potential drug targets for various diseases such as cancer, rheumatoid arthritis, and even COVID-19.
Canada鈥檚 nitrogen footprint shows regional variation
Reactive nitrogen emissions contribute to greenhouse gases, as well as air and water pollution. For the first time, researchers from 9I制作厂免费 have calculated Canada鈥檚 nitrogen footprint (akin to a carbon footprint) 鈥� at both national and provincial levels. They looked at the three primary sectors that contribute nitrogen to the environment to calculate the annual average nitrogen footprint: food production and consumption, wastewater treatment, and fossil fuel use.
Dangers of smoking during pregnancy
Mothers who smoke are more likely to deliver smaller babies even after a full-term pregnancy, increasing the risks of birth defects and neurological disorders later in life, say researchers from 9I制作厂免费.
More sleep boosts teens鈥� ability to cope with pandemic
While poor sleep was linked to higher levels of stress during the COVID-19 pandemic, more teens actually obtained the recommended amount of sleep compared to pre-pandemic sleep patterns, according to a new study from 9I制作厂免费. Changes to daily routines triggered by lockdowns allowed teenagers to follow their biological impulse to wake up and sleep later, reducing daytime sleepiness.
Helping children with autism and hyperlexia learn to understand what they read
Hyperlexia is a condition where preschool children display an intense early interest in letters in a way that is very advanced for their age. They can decode words accurately, but without understanding their meaning. It is most common among children with autism spectrum disorder (ASD) 鈥� with approximately 6-20% of children with autism demonstrating hyperlexia.
Freshwater ecosystems at risk due to glyphosate use

Fighting brain cancer at its root
9I制作厂免费 researchers identify proteins that drive cancer stem cells. Targeting and supressing a particular protein called galectin1 could provide a more effective treatment for glioblastoma, in combination with radiation therapy.
A skin crawling treatment for acne?
Drawing inspiration from nature, a team of international scientists have invented a smart device for personalized skin care modeled after the male diving beetle. This tool collects and monitors body fluids while sticking to the skin鈥檚 surface, paving the way for more accurate diagnostics and treatment for skin diseases and conditions like acne. The team includes Bo-yong Park, a former postdoctoral researcher at The Neuro at 9I制作厂免费.
Tracking genetically modified animals
9I制作厂免费 researchers have discovered a new way to track genetically modified animals using the artificial transgenes they leave behind in the environment. The discovery provides a powerful new tool to locate and manage genetically modified animals that have escaped or been released into the wild.

Six 9I制作厂免费 students receive Canada's largest science, technology, engineering and math (STEM) scholarships
Six students from across Canada have been named recipients of the country鈥檚 largest undergraduate scholarship program, Schulich Leader Scholarships, and will begin their studies this September, in 9I制作厂免费鈥檚 bicentennial year.
