Temperature changes have negatively impacted most species of bumble bees over the past 120 years, according to new research published this week in Biology Letters . The researchers note that changes in temperature had more of a negative impact than other factors - such as precipitation or floral resources.

A new study finds that having a portable air cleaner in the home can reduce the negative impacts of air pollution on brain development in children. Simon Fraser researchers collaborated with U.S. and Mongolian scientists to study the benefits of using air filters to reduce exposure to air pollution during pregnancy, and assessed the impact on children's intelligence.

Researchers at SFU's School of Interactive Arts and Technology (SIAT) urge parents and guardians to educate their children on the potential risks associated with biowearable technology devices when gifting this holiday season. Biowearable technology devices, or biowearables, are interactive smart devices worn on-body, such as smart watches and fitness trackers.

Researchers from Simon Fraser University and the University of Victoria have discovered a method-using only visible light-to treat and safely sterilize non-woven polypropylene-fabrics, the material used to fabricate personal protective equipment (PPE). Led by Tyler Cuthbert, a former SFU School of Engineering Science post-doctoral fellow, researchers tested a chemical insertion method developed by UVic chemistry professor Jeremy Wulff to attach a light-sensitive, zinc-based compound onto a non-woven polypropylene fabric.

Researchers are using artificial intelligence (AI) to detect behavioural signs of anxiety with more than 90 per cent accuracy, and suggest that AI could have future applications for addressing mental health and wellbeing. Their research is published in the journal Pervasive and Mobile Computing. "In the two years since the onset of COVID-19, and one climate disaster after another, more and more people are experiencing anxiety,- says SFU visiting professor and social psychologist Gulnaz Anjum.

Ancient Indigenous fishing practices can be used to inform sustainable management and conservation today, according to a new study from Simon Fraser University. Working with the Tsleil-Waututh Nation and using new palaeogenetic analytical techniques developed in SFU Archaeology's ancient DNA lab, directed by professor Dongya Yang, the results of a new collaborative study featured in Scientific Reports provides strong evidence that prior to European colonization, Coast Salish people were managing chum salmon by selectively harvesting males.

Research aimed at helping astronauts deal with isolation and confinement could also have an impact on those back on Earth suffering from COVID-related loneliness. Researchers in Simon Fraser University's iSpace Lab have created a virtual reality experience-called Earthgazing-which will be tested as part of SIRIUS 2021 , a study launching Nov.

Reducing ship speed and noise levels would increase the probability that endangered West Coast southern resident killer whales will spend more time hunting for Chinook salmon, a new Simon Fraser University study has found. The research, published in the journal Marine Pollution Bulletin , provides insights to guide conservation efforts and protect the estimated 73 remaining whales in the population.

Study traces 40 years of change on Vancouver Island river-to-sea salmon and trout pathway Researchers from Simon Fraser University's Salmon Watershed Lab have found that recent declines of Pacific salmon and trout are associated with 40 years of changes in their combined marine and freshwater ecosystems.

Microplastics are being found in even the most remote waters, say Simon Fraser researchers who studied how the particles ended up in the stomachs of beluga whales through prey.'? A new study published in the journal Science of the Total Environment looked at five species of arctic fish known to be eaten by beluga whales.

A new study published in the journal PLOS ONE from researchers at Simon Fraser University (SFU) and the University of British Columbia (UBC) has found that young adults feel highly responsible for protecting themselves and others against the spread of COVID-19, but face confusion when trying to comply with public health orders due to inconsistent messaging and ineffective outreach strategies.

New research by SFU archaeologists could help forensic teams in their work to estimate the age of the remains of children discovered during archaeological work or in criminal investigative cases. Their study is published in the journal Forensic Science International . While age is typically determined by dental records or other methods, such as measuring the long bones in the upper or lower limbs, those methods may not always be possible, especially in the case of young children.
