About one in five Canadian adolescents uses cannabis. Neuroscientists have been researching the effects of cannabis on the adolescent brain. Adolescence is associated with the maturation of cognitive functions, such as working memory, decision-making,…

Elderly patients with heart failure who see a pharmacist once a week are more likely to take their tablets and be active in daily life, according to new results.

Heart failure patients who consume more dietary fiber tend to have healthier gut bacteria, which is associated with reduced risk of death or need of a heart transplant.

New research showed that eating a diet with three times the recommended daily intake of linoleic acid might be harmful in pregnancy.

Women undergoing fertility treatment should urgently see their doctor if they have heart failure symptoms, according to a new study. Shortness of breath, swollen legs and waking up in the night to urinate could be warning signs of a pregnancy-associated heart…

A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to researchers who say they can create new types of…

Researchers have developed a novel solution to help reduce impact forces -- for potential applications in spacecraft, cars and beyond.

Using paper stickers to collect pathogens on surfaces where antisepsis is required, such as in food processing plants, is easier, and less expensive than swabbing, yet similarly sensitive.

A meta-analysis of nearly 300 studies of soil biodiversity in Amazonian forests found that the abundance, biomass, richness and diversity of soil fauna and microbes were reduced following deforestation.

A new study finds that the loss of marsh-edge salt grasses and mangroves due to disturbances such as heavy oiling from the 2010 Deepwater Horizon oil spill doubles the rate of shoreline erosion in hard-hit marshes.

New research finds that a special scan measuring lymphatic fluid volume is significantly better than a tape measure at predicting which women undergoing treatment for breast cancer are at risk of developing a common complication resulting from damaged lymph…

A team has discovered two Jupiter-sized planets about 150 light years away from Earth that could reveal whether life is likely on the smaller planets in other planetary systems.

Researchers used the power of artificial intelligence and high-performance supercomputers to introduce and assess the impact of different configurations of defects on the performance of a superconductor.

Researchers have discovered a new function of ribosomes in human cells that may show the protein-making particle's role in destroying healthy mRNAs, the messages that decode DNA into protein.

A first-of-its-kind comparison between elite pro athletes suggests higher overall mortality among NFL players compared with MLB players. NFL players also appear to have higher risk of dying from cardiovascular and neurodegenerative causes compared with MLB…

To treat Candida albicans, a common yeast that can cause illness in those with weakened immune systems, researchers limited the fungus' access to iron, an element crucial to the organism's survival.

New findings provide insights about how the intestine maximizes nutrient uptake, while at the same time protecting the body from potentially dangerous microbes.

Control engineers and AI experts team up to make drones that fly more smoothly close to the ground.

New research shows that cancer cells of glioblastomas -- conspicuously aggressive solid brain tumors -- manifest developmental plasticity and their phenotypic characteristics are less constrained than believed.

A new study found that infants at high risk for autism were less attuned to differences in speech patterns than low-risk infants. The findings suggest that interventions to improve language skills should begin during infancy for those at high risk for autism.

Adding genomic sequencing results to traditional newborn screening means a baby could potentially test positive for numerous conditions that might not develop within their lifetime. A new study proposed a method for how to responsibly determine which types of…

More and more processes are being automated. Self-driving delivery vehicles are finding their way into many areas. However, an interdisciplinary research team has observed that cooperation between humans and machines can work much better than just human or…

Scientists studying a lithium-ion battery with an iron-oxide electrode as it charged and discharged over 100 cycles found that the loss is due to a buildup of lithium oxide and decomposition of the medium through which lithium ions flow.

Preventing the introduction of the mosquitofish and removing its population are the most effective actions to control the dispersal of this exotic fish in ponds and lakes, according to a new study.

New research elucidates the mechanism that keeps maize distinct from its ancient ancestor grass, teosinte.

Researchers have developed a new test that can easily and simply measure common stress hormones using sweat, blood, urine or saliva. Eventually, they hope to turn their ideas into a simple device that patients can use at home to monitor their health.

Dengue, also known as dengue fever, is a viral disease transmitted to humans by mosquitoes of the genus Aedes. The incidence of dengue is currently increasing dramatically, and it is now one of the diseases said to be re-emerging. Researchers have conducted a…

What effects does climate change have on the genetic diversity of living organisms? In a new study, researchers studied the genome of the alpine marmot. Results were unexpected: the species was found to be the least genetically diverse of any wild mammal…

Cells in the body are wired like computer chips to direct signals that instruct how they function, research suggests. Unlike a fixed circuit board, however, cells can rapidly rewire their communication networks to change their behavior. The discovery of this…

As indicated by a recently published study, short-term opioid use shifts a range of emotional responses to the positive direction. This may be one of the reasons behind the onset of opioid use disorder.
