Clot-busting drug used for heart attacks effective in treatment of stroke

Could become the standard treatment for acute ischemic stroke

Clot-busting drug used for heart attacks effective in treatment of strokeTenecteplase (TNK), a common clot-busting drug used in people suffering from a heart attack, is a safe and effective treatment for those in the midst of acute ischemic stroke, reports a University of Alberta research team involved in the largest stroke clinical trial in Canadian history. Brian Buck, a neurology professor in the University of…

Mild electrical stimulation could boost cognitive ability

Pilots, athletes, dementia patients and more could benefit from this brain boost

Mild electrical stimulation could boost cognitive abilityImagine putting on a helmet embedded with tiny electrodes that sit on your scalp, delivering a gentle electrical current to certain areas of your brain. After about 10 to 20 minutes, you might find yourself with a better ability to focus, sharper memory and a host of other cognitive benefits. That’s the idea behind a…

Technology should never be the driving force behind education reform

Students need more time reading books and less time reading screens. Good teaching, not more technology, is key

Technology should never be the driving force behind education reformTechnology has had a huge impact on public education. Classrooms of today look quite different from those of a generation ago. It shows just how quickly technology changes and the extent to which it dominates our children’s lives. However, while it makes sense to ensure that students and teachers have reasonable access to computers, technology…

Researchers can identify people with PTSD through text data alone

Machine learning model has potential to be developed into an accessible and cost-effective tool

Researchers can identify people with PTSD through text data aloneUniversity of Alberta researchers have trained a machine learning model to identify people with post-traumatic stress disorder (PTSD) with 80 per cent accuracy by analyzing the text those people wrote. The model could one day serve as an accessible and inexpensive screening tool to support health professionals in detecting and diagnosing PTSD or other mental health…

Why we should ignore teen advice on policy issues

Teenagers have virtually no life experience and no expertise but are feted as if they were Einstein

Why we should ignore teen advice on policy issuesBy Mark Milke and Martin Mrazik The Aristotle Foundation for Public Policy The war on Ukraine instigated by Russian President Vladimir Putin should be a reminder that adults and their experiences and judgments matter, i.e. thinking through whether we wish to go to war with Russia. However obvious that seems, in recent years – on…

VR technology could reveal how the brain forms memories

Understanding how the brain forms real-world memories has been elusive

When you think of a vivid personal memory, you don’t merely recall the bare facts of what happened – you remember additional details like the emotions you felt, perhaps where you were standing when things unfolded, scents and sounds in the air. “Memories play such a key component in shaping who we are,” said Peggy St.…

Brain science and theatre background provide a unique perspective

Professor's experimental approach explores science, technology, society and the environment

Brain science and theatre background provide a unique perspectiveFor Yelena Gluzman, science and theatre have much in common. And she’s intimately familiar with both. That makes her a great fit as the newest addition to Media and Technology Studies in the Faculty of Arts at the University of Alberta, where she’s teaching a new course on the interrelations of science, technology, society and environment.…

Brain-computer interface connect people with assistive technologies

Device would allow children with severe mobility issues to control toys or wheelchairs with their minds

Brain-computer interface connect people with assistive technologiesImagine children with severe mobility issues being able to move their wheelchairs with their minds. That’s the idea behind a new brain-computer interface being developed by researchers at the Universities of Alberta and Calgary. Think2Switch is designed to be a simple and nearly universal bridge connecting brain signals to switch-enabled devices such as a wheelchair,…
