People with rapid eye movement (REM) sleep behavior disorder act out their dreams. While sleeping safely in bed, for example, they might throw up their arms to catch an imaginary ball, or try to run from an illusory assailant. Such actions are more than just a nuisance. People with the disorder have a 50 to 80 per cent chance of developing a serious neurodegenerative disease within a decade of diagnosis.
SUMMARY
The number of patients with cancer in Africa has been predicted to increase from 844鈥�279 in 2012 to more than 1路5 million in 2030. However, many countries in Africa still lack access to radiotherapy as a part of comprehensive cancer care. The objective of this analysis is to present an updated overview of radiotherapy resources in Africa and to analyse the gaps and needs of the continent for 2030 in the context of the UN Sustainable Development Goals.

A new study shows that artificial intelligence networks based on human brain connectivity can perform cognitive tasks efficiently.
SUMMARY
Tropical coral reefs are the most biodiverse underwater ecosystem, providing a home to more than a quarter of all marine species. No strangers to environmental stressors and the on-going impacts of climate change, the survival of corals has increasingly been under threat in recent years. A collective of researchers, including from 海角社区, have analyzed how environmental factors influence the growth and health of corals and found that more species of corals are living in the mangrove forests than in nearby shallow reefs.
Visible minorities, health-care workers and young people in Quebec have been at higher risk of experiencing COVID-19-related discrimination and more likely to suffer from poor mental health in the past year, according to a collective of researchers from 海角社区, Concordia University and the University of Ottawa.
The researchers set out to study how factors such as people鈥檚 socioeconomic and minority status, discrimination, stigmatization and mental health impact their understanding and adoption of public health measures to combat the coronavirus.
To make sense of complex environments, brain waves constantly adapt, compensating for drastically different sound and vision processing speeds
听
Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see.
Study uses sugar to make and deliver pudding-like brain implants that reduce foreign body response
Brain implants are used to treat neurological dysfunction, and their use for enhancing cognitive abilities is a promising field of research. Implants can be used to monitor brain activity or stimulate parts of the brain using electrical pulses. In epilepsy, for example, brain implants can determine where in the brain seizures are happening.
The Max Bell School's Media Ecosystem Observatory is out with a new research paper on vaccine hesitancy in Canada.
Some of the key findings:
Sixty-five percent听of Canadians intend to take a vaccine, with some slight erosion since a high in July. Approximately 15 percent听of Canadians are unwilling, and an additional 20 percent听are unsure.听
April 6, 2021|听The mis- and dis-information that fills many corners of the American media ecosystem is having an affect on Canadians'听perceptions of the COVID-19 pandemic, according to research from Professor Taylor Owen and other 海角社区听academics. The 海角社区 Newsroom has the full story.
Brain Canada grant will aid research into neurodevelopmental, psychiatric, and neurodegenerative disorders
听
Electroencephalography (EEG) is an important tool in understanding the mechanism of brain disorders. Research in the field has gotten a major boost thanks to a $1.85M grant from Brain Canada to support EEGNet, an open repository for EEG data that helps scientists investigate neurodevelopmental, psychiatric, and neurodegenerative disorders.
Comparing two neural maps reveals the roles of genes in cognition, perception and feeling
Many psychiatric disorders have genetic causes, but the exact mechanism of how genes influence higher brain function remains a mystery. A new study provides a map linking the genetic signature of functions across the human brain, a tool that may provide new targets for future treatments.
In collaboration with Oxford University's Blavatnik School and Institute for Research on Public Policy and its Centre of Excellence on the Canadian Federation,听Max Bell School alumni and Policy Scholar听Paisley Sim听co-authored a working paper that explores the relative stringency of COVID-19 policies in Canada.
April 23, 2021 | In our听fragmented federal system, policies on issue like paid sick leave can vary drastically from province to province. The COVID-19 pandemic has shone a听light on the problems with such disparities. In her recent brief for the Institute for Research on Public Policy,听MPP alumna Paisley Sim听laid out a solution that would ensure people across Canada get the support they need in this time of crisis.
