Two substances never before seen on Earth identified

Two substances never before seen on Earth identifiedNew minerals discovered in massive meteorite may reveal clues to asteroid formation A team of researchers has discovered at least two new minerals that have never before been seen on Earth in a 15-tonne meteorite found in Somalia – the ninth-largest meteorite ever found. “Whenever you find a new mineral, it means that the actual…

Engineering clubs a path to a future career

Student clubs offer a taste of what it means to work together on a multifaceted design project

Engineering clubs a path to a future careerEngineering clubs are created by students and for students. They provide a sandbox that lets future engineers make new things, sometimes starting with mistakes. COVID-19 jeopardized the clubs, but they’re coming back strong and punching above their weight. “It’s not something that you expect a group of students to take on because of the technical…

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…

Why do more females than males get knee osteoarthritis?

Hormones alone are not enough to explain the difference

Why do more females than males get knee osteoarthritis?Female astronauts could avoid knee injuries during space flight – and better tests, prevention and treatments could be developed for knee osteoarthritis in women on Earth – based on newly published research on the sex differences in knee meniscus tissue. Knee osteoarthritis is more common in females than in males, but hormones alone are not…

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…

Physicists create new model to hunt for colliding neutron stars

Speeds up search to observe collisions in first hours when scientists can learn most

Physicists create new model to hunt for colliding neutron starsUniversity of Alberta physicists have created a new, simpler way to model collisions between neutron stars. The model will enable scientists to predict the brightness of early neutron star mergers more reliably than before – allowing telescopes to gain more information from these events. “Studying the light and electromagnetic waves emitted from these collisions allows…

Engineer credits Schulich scholarship for launching aerospace career

Kirtan Dhunnoo credits the scholarship for giving him incredible experiences and job-ready skills

Engineer credits Schulich scholarship for launching aerospace careerEven as a student at Edmonton’s Strathcona High School back in 2014, Kirtan Dhunnoo had a keen understanding of the potential for leadership in each of us. “Not only are there leaders by labels, but there are leaders by virtue of their widely different personalities,” he wrote in his application for a Schulich Leader Scholarship.…

Space designers take flight to test bioengineered knee cartilage in low gravity

Device built by U of A team could help researchers learn how osteoarthritis develops

Space designers take flight to test bioengineered knee cartilage in low gravityMembers of a University of Alberta student club are walking on air after testing samples of bioengineered knee cartilage in a reduced-gravity experiment competition. Amira Aissiou and Kirtan Dhunnoo of the University of Alberta Space Design Group strapped themselves in and went for a wild ride in the Canadian Space Agency’s Falcon 20 parabolic aircraft to get a…

We can’t just laugh off unidentified aerial phenomena

The observers of these phenomena are sober professionals who seek to understand what it is that has been detected and recorded

We can’t just laugh off unidentified aerial phenomenaThe venerable television program 60 Minutes aired a segment recently focused on a topic that has been examined before, but not with the same widespread receptivity and credibility. It had to do with UAPs. And the Pentagon, directed by the United States Congress, recently released its file on UAPs, or unidentified aerial phenomena. These sightings…

Fireball was a comet fragment burning up in Earth’s atmosphere

U of A scientists use fireball monitoring network to capture images of the meteor that lit up the skies over Western Canada

Fireball was a comet fragment burning up in Earth’s atmosphereWestern Canadians caught a glimpse of a bright flash overhead this week as a fireball lit up the sky on the morning of Feb. 22. Now, University of Alberta researchers have used Western Canada’s most advanced fireball network to capture images and trajectory of the fireball – revealing it to be a small piece of…
