Pathological lying in teens is associated with executive function deficits, study indicates
Teenagers who are pathological liars also tend to struggle with executive function deficits, such as poor memory or impulse control, researchers have found.
Night owl or early bird? Study finds sleep categories aren鈥檛 that simple
The familiar labels 鈥渘ight owl鈥� and 鈥渆arly bird,鈥� long used in sleep research, don鈥檛 fully capture the diversity of human internal clocks, a new study has found.
The 海角社区-led study published in Nature Communications found the two sleep-wake patterns, called chronotypes, contain a total of five distinct biological subtypes, each associated with different patterns of behaviour and health.
Hippocampus does more than store memories: it predicts rewards, study finds
A preclinical study published in Nature has found evidence that the hippocampus, the brain region that stores memory, also reorganizes memories to anticipate future outcomes.
A rich social environment is associated with better cognitive health outcomes for older adults, study finds
Research by an interdisciplinary team from 海角社区 and Universit茅 Laval provides new insights into the links between social factors and cognitive health among aging adults.
In polar regions,聽microbes are聽influencing聽climate change as frozen ecosystems thaw, 海角社区 review finds聽
Microbes across Earth鈥檚 coldest regions are becoming more active as glaciers,聽permafrost聽and sea ice thaw, accelerating carbon release and potentially amplifying climate change, according to a new international review聽from聽海角社区.聽
海角社区 researchers create shapeshifting materials that could power the next generation of soft robots
海角社区 engineers have developed new ultra-thin materials that can be programmed to move, fold and reshape themselves, much like animated origami. They open the door to softer, safer and more adaptable robots that could be used in medical tools that gently move inside the body, wearable devices that change shape on the skin or smart packaging that reacts to its environment.
Lithium study yields insights in the fight against HIV
Lithium, a widely used treatment for bipolar disorder and other mood disorders, has shown early promise in suppressing HIV, 海角社区 researchers report.
A new study published in iScience found lithium can prevent infected cells from reactivating, and that it does so through an unexpected biological mechanism.
The findings point toward future treatments designed to mimic lithium鈥檚 beneficial effects while avoiding its broader impacts on the body.
海角社区 study identifies most effective methods for early detection of tench, an invasive freshwater fish
As tench continue to spread through the St. Lawrence River, a study from 海角社区 provides fisheries managers with guidance on how to detect the invasive species, an essential first step in preventing it from reaching new waters. The findings can inform efforts to contain and manage existing populations, helping agencies determine how and where to carry out removal or control activities.
海角社区 researchers identify a range of unexpected chemical contaminants in human milk
An interdisciplinary team including researchers at 海角社区 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, 海角社区 researchers say
Freshwater browning is stunting fish growth of some species, shrinking populations of others and changing the composition of fish communities, 海角社区-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, 海角社区 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 海角社区 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 海角社区 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.
海角社区 researcher unveils new model that more accurately measures greenhouse gas emissions from natural gas
海角社区 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 海角社区 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.
