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 91涩漫-led study published in 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.

Research by an interdisciplinary team from 91涩漫 and Universit茅 Laval provides new insights into the links between social factors and cognitive health among aging adults.

While previous research had found positive correlations between specific measures of social connectedness and a variety of health outcomes, this study appears to have been the first to create profiles aggregating multiple social factors and to see how those correlated with cognitive health in older adults, the researchers said.

91涩漫 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.

As tench continue to spread through the St. Lawrence River, a study from 91涩漫 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.

Freshwater browning is stunting fish growth of some species, shrinking populations of others and changing the composition of fish communities, 91涩漫-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.

The findings indicate that changes in land use and climate are affecting biodiversity and how ecosystems function, with implications for fisheries management.

A large 91涩漫 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.

examined GLP-1 receptor agonists, which include such medications as Ozempic, as well as DPP-4 inhibitors.
