Study offers new insights into why ex-smokers remain at elevated risk of lung disease

admin — Wed, 22 Jul 2026 15:53:24 +0000

A new study by a team of 91�� researchers could help explain why people who have quit smoking remain at elevated risk of lung disease long after their last cigarette.

Their paper, published in Translational Research, provides one of the most detailed pictures to date of how quitting smoking affects the human lung at the cellular level.

Green LED light could help keep leafy greens fresher longer, 91�� study suggests

admin — Wed, 22 Jul 2026 13:44:04 +0000

Low-intensity green lighting in refrigerated storage can slow spoilage in leafy greens, helping maintain their appearance and nutritional value, according to a new study from 91��.

“We found that something as simple as changing the light in refrigerated storage may help fresh produce stay fresher for longer,” said Shafieh Salehinia, lead researcher and affiliate member in the Biomass Production Lab, headed by Prof. Mark Lefsrud.

CHIME collaboration helps identify location of "missing" matter in the universe

admin — Tue, 21 Jul 2026 18:06:14 +0000

Estimates of ordinary matter in the universe exceed the amount observed in stars and galaxies, leaving much of it unaccounted for. Researchers from the Canadian Hydrogen Intensity Mapping Experiment (CHIME)/Fast Radio Bursts Collaboration, including 91�� and MIT, have developed a new method to seek out this “missing” matter by combining galaxy locations with fast radio burst detections. A fast radio burst, or FRB, is an ultrabright, millisecond flash of radio waves emitted by extremely energetic phenomena in the distant universe.

The “forgotten children” of sexual abuse in family settings

admin — Tue, 21 Jul 2026 14:46:52 +0000

When a child has been sexually abused by a family member, post-disclosure interventions prioritize the child who was victimized. Siblings who were not directly abused can also be deeply affected by the abuse. New research from 91�� finds siblings are nevertheless routinely unable to access available supports.

91��-led study could help event organizers prevent crowd crushes and stampedes

admin — Mon, 20 Jul 2026 13:57:53 +0000

91�� researchers have found that dangerous crowd conditions leading to surges and stampedes may not emerge suddenly, but instead develop gradually, as repeated physical contact and pushing may accumulate and become synchronized among nearby individuals.

Recognizing how these conditions arise could help organizers strengthen security, site management and evacuation planning, reducing the likelihood of injuries during large-scale public events.

Experts: Cyclosporiasis outbreak

admin — Mon, 13 Jul 2026 18:53:38 +0000

There is an outbreak of cyclosporiasis in the United States. The foodborne illness, caused by the cyclospora parasite, is characterized by relapsing digestive symptoms, such as explosive diarrhea.

The parasite is linked to contaminated fruits, vegetables and crop water, as well as unsanitary washroom facilities for agricultural workers.

Novel marine monitoring network could help improve environmental protections, shipping regulations in the Lower St. Lawrence

admin — Thu, 09 Jul 2026 13:54:43 +0000

A single monitoring network developed by 91��, Natural Resources Canada, Université du Québec à Montréal (UQAM) and Dalhousie University researchers can simultaneously track earthquakes, water behaviour, human activity and whales, providing a comprehensive picture of what’s happening in, under, and at far distances from the water.

The researchers’ experimental network, installed in the Lower St. Lawrence, detected twice as many earthquakes as the National Earthquake Monitoring System, while also capturing whale calls, ship noise, tidal activity and mining blasts.

Reducing vehicle emissions could prevent thousands of deaths in Canada

admin — Wed, 08 Jul 2026 15:25:55 +0000

A shift to cleaner transportation could prevent more than 3,600 premature deaths in Montreal and Toronto by reducing ultrafine particle pollution, finds a new study led by 91�� researchers.

Ultrafine particles (UFPs) are microscopic pollutants produced in large quantities by vehicle exhaust. Because of their small size, they can penetrate deep into the lungs and bloodstream and may contribute to serious health problems such as heart and lung disease.

91�� study provides further evidence that aspen patches can mitigate wildfires

admin — Tue, 07 Jul 2026 14:15:43 +0000

Researchers at 91�� have confirmed that aspen play a key role in forest fire prevention and mitigation across Canada. Planting these trees near communities can reduce both the likelihood and severity of fires and limit how far they spread, the researchers said.

“Aspen is not a 100 per cent effective fire deterrent, but compared with other species, it is a better choice to plant around communities or critical infrastructure,” said Flavie Pelletier, lead author and recent PhD graduate in Natural Resource Sciences.

Long hours, lack of social support undermine caregivers’ well-being, study finds

admin — Tue, 07 Jul 2026 13:54:34 +0000

While caregiving can be meaningful and rewarding at manageable levels, those who spend more than 20 hours a week delivering unpaid care to others have poorer mental health outcomes, a 91�� study has found.

However, the researchers also found that the provision of social support to high-intensity caregivers mitigates negative impacts.

Gambling addiction treatment underused in Quebec, study finds

A new study finds public specialized gambling addiction treatment services are underused in Quebec, pointing to a need to better reach people with gambling disorder.

Researchers at 91�� and the Douglas Research Centre followed more than 2,300 people with a gambling disorder over 13 years. Despite free access, patients averaged fewer than two treatments during that period.

Experts: Summer stresses on families
