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…

Oil sands water reclamation materials put to commercialization test

Analysis tool could help companies decide which innovations are worth the investment

Oil sands water reclamation materials put to commercialization testEnvironmental reclamation is necessary, but sometimes it’s expensive for industry. What materials work best? Which ones are worth the investment? University of Alberta researchers are inching closer to answering those pressing questions through a project that looks at two reclamation materials with commercial potential: chicken feathers and biochar, a blackened byproduct created from waste like cow…

Lasers could revolutionize medicine, future energy needs

Evidence suggests laser-based fusion energy could actually be a viable

Lasers could revolutionize medicine, future energy needsA beam of protons painlessly penetrates human tissue until it terminates inside a cancer tumour, where each particle deposits a micro-explosion of radiation energy. The beam is precisely calibrated, targeting only the tumour and leaving surrounding tissue unharmed. Called “proton therapy,” this revolutionary medical treatment is just one application of a relatively new technology using…

Teaching a computer to read doctors’ notes will capture valuable data

Algorithm scans pathology, radiology reports for information to aid researchers in improving outcomes

Teaching a computer to read doctors’ notes will capture valuable dataEvery time you enter a phrase or a sentence into Google search, algorithms kick in using a technique called natural language processing to understand what you really want to know and then find you an answer. Now University of Alberta researchers will use a similar approach to develop a computer program that can “read” doctors’…

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.…

Driving artificial scarcity is not the way to effectively deploy 5G

Any gains in competition are more than outweighed by higher spectrum costs

Driving artificial scarcity is not the way to effectively deploy 5GLast December, the federal government launched a consultation for the auction of the 3800 MHz spectrum to help foster the effective deployment of 5G wireless telecommunications. As in previous auctions, the plan is to set aside a significant part of the available spectrum for smaller players, which the main wireless telecom providers are prohibited from…

New report sheds light on future of mobility in Canada’s big cities

Innovation will depend as much on social factors as technological ones

New report sheds light on future of mobility in Canada’s big citiesIncreasingly, urban dwellers are looking for new and more sustainable ways to move around their cities. Technologies like autonomous vehicles and electric scooters may be top of mind for urban planners, but social and cultural factors may be just as important in helping Canadian cities prepare for the future, according to a co-author of a…

Free, easy-to-use tool could reduce unnecessary prostate cancer biopsies

Risk calculator pinpoints suitable patients for guided biopsies that improves the current standard of care

Free, easy-to-use tool could reduce unnecessary prostate cancer biopsiesA new risk calculator developed by a University of Alberta researcher and collaborators in the United States could reduce the number of unnecessary and invasive biopsies for prostate cancer. Adam Kinnaird, a surgeon and assistant professor in the Faculty of Medicine & Dentistry, said the tool is available online for free, requires only conventional clinical data paired with…

Researchers find new uses for oil sands leftovers

Engineering projects explore three ways to turn a component of bitumen into carbon fibre

Researchers find new uses for oil sands leftoversCarbon fibre is strong, light and resistant to corrosion, making it ideal for composites used in various products. Think of wheelchairs, bikes, buses, construction materials and more. Unfortunately, it’s expensive to produce. That’s a problem three researchers in the University of Alberta’s Faculty of Engineering – Cagri Ayranci, Kevin Hodder and Zhi Li – are trying to solve by…

James Webb Space Telescope is next chapter for ‘mega-science’

The most complex scientific spacecraft ever built reaches its destination a million miles away

James Webb Space Telescope is next chapter for ‘mega-science’As the James Webb Space Telescope reaches its destination, a million miles from Earth, University of Alberta space historian Robert Smith will be watching almost as closely as scientists in NASA’s control room. Smith has staked his career on documenting every phase of the Webb and Hubble telescopes over the past four decades and is recognized as the on-the-scene historian…
