Canada’s response to restricting access to the country by non-citizens has changed rapidly since the start of the COVID-19 pandemic, culminating with Prime Minister Justin Trudeau finally announcing a closure of the Canada-U.S. border to “non-essential travel” while still allowing food, goods and medical supplies to cross.

Homeless people receive less treatment in hospitals for heart attacks, have higher readmission rates
ROCHESTER, Minn. -- Homelessness has become a social crisis and public health problem around the world, affecting people of all ages. Most homeless people are at a disadvantage with few resources, and may or may not have adequate health insurance. Mental illness and substance abuse are common issues in the homeless community. People living on the streets have a high likelihood of developing heart disease. Yet they have little ability to take care of their health.
An international team of scientists, led by the University of Bristol, has found that current estimates of flood risk rely upon methods for calculating flood damage which are inadequately verified and match poorly with observations.
Instead, building damage at a given flood depth is highly variable and can be characterized by a beta distribution.
Automated Scanning Probe Microscopy (SPM) controlled by artificial intelligence
First demonstration of fully autonomous, long-term SPM operation
An Australian-German collaboration has demonstrated fully-autonomous SPM operation, applying artificial intelligence and deep learning to remove the need for constant human supervision.
The new system, dubbed DeepSPM, bridges the gap between nanoscience, automation and artificial intelligence (AI), and firmly establishes the use of machine learning for experimental scientific research.
They are among the most common ailments for those residing at post-acute and long-term care (PALTC) centers, yet diagnosing and managing urinary tract infections (UTIs) remains a challenging prospect for caregivers at these facilities.
Researchers working towards understanding the brain in high-definition, single-cell level of detail have designed a new computer program to identify each nerve cell in fluorescent microscope images of living worms. Previous attempts to automate the identification of individual nerve cells have been thwarted by the fact that the same cell can be in vastly different locations in different worms.
Negligence claims against the NHS due to failure to inform patients before they consent to procedures have spiralled up since a landmark legal ruling in 2015, a new study has found.
The research, conducted by Queen Mary University of London, found that while the rate of increase of other claims has remained steady, cases relating to consent have risen fourfold overall since March 2015 - and where failure to inform was added as a contributory claim, the rise was nearly ten-fold.
An investigation by The BMJ has uncovered links between groups and individuals campaigning for wider access to cannabis for medical reasons and those pushing for the legalisation of cannabis for recreational use.
It also explores how a research collaboration that includes Oxford University is taking funding from the tobacco industry for research into the medicinal properties of cannabis.
Findings from a phase 2 clinical trial show that the drug selumetinib improves outcomes for children with the genetic disorder neurofibromatosis type 1 (NF1). In the trial, selumetinib shrank the inoperable tumors that develop with NF1 called plexiform neurofibromas, and children experienced reduced pain, improved function, and better overall quality of life after receiving the treatment.
Scientists using sophisticated genetic analysis techniques have found that some fish are better than others at coping with heatwaves.
A world-first study tracked how wild fish populations responded to a severe marine heatwave, focussing on the 2016 event that killed a third of the Great Barrier Reef corals.
A puzzling modification of DNA that is common in bacteria is not present in humans or other mammals. This has been shown in a new study by scientists at Linköping University in Sweden, published in Science Advances. The study shows that detection of the epigenetic mark 6mdA in animals was probably the result of limitations of the technology used and bacterial contamination of samples.
WASHINGTON, DC--A groundbreaking study by Resources for the Future (RFF) researchers, to be published in Science Advances March 18, 2020 at 2:00 pm EDT, shows that national monuments have had mostly positive effects on local economies in the American West.
Study authors Margaret Walls, Patrick Lee, and Matthew Ashenfarb highlighted the following key findings:
After the monuments were designated, the number of nearby business establishments and jobs increased by an average of 10 percent and 8 percent, respectively, compared to "control" areas.
A recent study in mice led a team of researchers in Japan to believe that psychosis may be caused by problems with specialized nerve cells deep within the brain, as well as a certain kind of learning behavior. The researchers hope this could provide insight into the emergence of delusions in patients with psychosis or schizophrenia with the aim of finding ways to help them.
The oldest fossil of a modern bird yet found, dating from the age of dinosaurs, has been identified by an international team of palaeontologists.
The spectacular fossil, affectionately nicknamed the 'Wonderchicken', includes a nearly complete skull, hidden inside nondescript pieces of rock, and dates from less than one million years before the asteroid impact which eliminated all large dinosaurs.
Two new studies from Karolinska Institutet in Sweden underscore health risks associated with childhood obesity. Children with obesity have a three times higher risk of mortality in early adulthood compared with children in the general population and are more likely to suffer from anxiety and depression. The findings, published in PLOS Medicine and BMC Medicine, highlight the need to identify specific risk factors for children with obesity and find preventative tools, according to the researchers.
