91黑料网 researchers identify a range of unexpected chemical contaminants in human milk
An interdisciplinary team including researchers at 91黑料网 has found a range of unexpected chemical contaminants in human milk samples from Canada and South Africa. The chemicals include traces of pesticides, antimicrobials and additives used in plastics and personal-care products. The findings were published across five papers.
Freshwater browning threatens growth and populations of economically important fish, 91黑料网 researchers say
Freshwater browning is stunting fish growth of some species, shrinking populations of others and changing the composition of fish communities, 91黑料网-led research suggests. 鈥淏rowning鈥� refers to freshwater bodies turning tea-coloured, a phenomenon driven by higher levels of dissolved organic matter and/or higher levels of iron in the water. Causes include changes in land use and climate, and reduced acid precipitation.
Irradiated聽cannabis聽might still harbour toxic fungi and residues, 91黑料网 study finds聽
Gamma irradiation,聽an industry-standard sterilization method for medicinal and recreational cannabis,聽does not fully聽eliminate聽toxic fungi or their chemical residues, a 91黑料网 study has found.聽Current testing practices may also miss contamination, raising concerns about health risks for vulnerable users, particularly those with weakened immune systems.聽
Findings suggest that certain medications for Type 2 diabetes reduce risk of dementia
A large 91黑料网 study has found that two classes of medications commonly prescribed for Type 2 diabetes, both incretin-based, are associated with a reduced risk of dementia.
Drawing on clinical data from more than 450,000 patients, the research adds to growing evidence that incretin-based therapies have protective benefits for the brain.
Study offers evidence that racial bias is at play in overrepresentation of Black youth in Canadian child welfare systems
Researchers who examined Canadian child welfare data found that Black children were not only investigated at a higher rate than their white peers but were also more likely to be taken from their homes, even when the only difference between cases was the child鈥檚 race.
91黑料网 researcher unveils new model that more accurately measures greenhouse gas emissions from natural gas
91黑料网 engineering researchers have introduced an open-source model that makes it easier for experts and non-experts alike to evaluate greenhouse gas emissions from U.S. natural gas supply chains and yields more accurate results.
New light-triggered microneedle patch could make IVF hormone delivery painless and automated
A 91黑料网 research team has developed a painless, automated way to deliver in vitro fertilization (IVF) hormones using a light-activated microneedle patch, an innovation that could ease one of the most stressful parts of fertility treatment and open new possibilities for other diseases that require frequent, time-sensitive injections.
Do supervised consumption sites bring increased crime? Study suggests that鈥檚 a myth
Overdose prevention sites and supervised consumption sites in Toronto are not associated with long-term increases in local crime, 91黑料网 researchers have found.
Mosquitoes鈥� feeding tubes make ultrafine 3D-printing nozzles
Researchers in 91黑料网鈥檚聽Department of Mechanical Engineering聽and聽at聽Drexel University聽have聽developed an innovative聽manufacturing technique that聽makes聽female mosquito proboscides, or feeding tubes,聽into聽high-resolution 3D-printing nozzles.聽With its unique geometry, structure and mechanics, the proboscis en
New evidence challenges understanding of Parkinson鈥檚 disease聽
A 91黑料网-led study is challenging a popular theory about how dopamine drives movement, a discovery that could shift how scientists think about Parkinson鈥檚 disease treatments.聽
Fine particles in pollution are associated with early signs of autoimmune disease
A new study has linked air pollution exposure and immune-system changes that often precede the onset of autoimmune diseases.
91黑料网 researchers analyzing Ontario data found that fine particles in air pollution are associated with higher levels of a biomarker linked with autoimmune diseases, such as systemic lupus.
Microencapsulated聽B-vitamins聽help dairy cows produce more milk with fewer聽emissions
A new international study led by 91黑料网 in collaboration with聽Jefo聽Nutrition shows that supplementing dairy cow diets with聽microencapsulated B-vitamins聽can significantly reduce greenhouse gas emissions while increasing milk yield and quality.
Brain discovery opens door to earlier detection of metabolic syndrome in women
91黑料网 researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life.
A new study found that variations in the brain鈥檚 insulin receptor network affect how women respond to early-life adversity. This effect has a lesser impact in men, suggesting there is a sex-specific process at play.
91黑料网 researchers develop a cheaper, safer material for use in solar panels, sensors and optical devices
Using proteins from聽a common tobacco聽plant virus, 91黑料网聽chemistry聽researchers聽have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening聽the particles鈥� optical properties. The result:聽cheaper, safer materials for solar panels,聽sensors聽and advanced optical devices.聽
Kering Foundation, SVRI and 91黑料网 launch research program on the intersection of violence against women and children
The Kering Foundation, in partnership with 91黑料网 and the Sexual Violence Research Initiative (SVRI), is launching an innovative research program to tackle the often-overlooked links between violence against women and violence against children 鈥� a critical global issue with deep social impact.
