How bacteria create a piggy bank for the lean times
Bacteria can store extra resources for the lean times. It鈥檚 a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years ago. He saw big, dark splotches in the cells of the blue-green algae (cyanobacteria) he was studying without understanding either what they were or their purpose.
By 2500 earth could be alien to humans
To fully grasp and plan for climate impacts under any scenario, researchers and policymakers must look well beyond the 2100 benchmark. Unless CO2 emissions drop significantly, global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in, according to a team of international scientists.
Older adults are more willing to help others, but mostly those in the same country
Older adults are more willing to help others compared to younger adults but will prioritize those within their own country 鈥� particularly when it comes to donating to charity. This group was also more compliant with public health guidelines for physical distancing during the COVID-19 pandemic, according to a team of international researchers.
$2.5 million for the creation of the R茅seau qu茅b茅cois de recherche en agriculture durable
Today, the Fonds de recherche du Qu茅bec - Nature et technologies (FRQNT), along with its partner the minist猫re de l'Agriculture, des P锚cheries et de l'Alimentation (MAPAQ) announced the creation of the R茅seau qu茅b茅cois de recherche en agriculture durable (RQRAD), a flagship measure of the Plan d鈥檃g
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 成人VR视频 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 成人VR视频 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 成人VR视频 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 成人VR视频.
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 成人VR视频. 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
One of the few species that was found to be resistant to severe glyphosate contamination was Scapholeberis mucronata, a freshwater zooplankter commonly found in Qu茅bec and elsewhere in North America. CREDIT: Marie-Pier H茅bert
Fighting brain cancer at its root
成人VR视频 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 成人VR视频.
