Canada’s National Artificial Intelligence Strategy: AI for All
Message from the minister The Government’s vision: AI for All Key pillars of the strategy Priority sectors Pillar 1: Protecting Canadians and safeguarding democracy Pillar 2: Ensuring AI empowers Canadians Pillar 3: Powering AI adoption for shared prosperity Pillar 4: Building the Canadian sovereign AI foundation Pillar 5: Scaling Canadian champions Pillar 6: Building trusted partnerships and global alliances Conclusion
An innovative Canada is a stronger Canada. And AI is the major driver of innovation in Canada and around the world. But to understand the potential of Canadian AI, you have to see how it is already working to improve the lives of people. How a Canadian pediatric cardiologist in Halifax named Dr. Robert Chen is using the AI application he built to diagnose heart murmurs in newborns. His technology could cut down wait times by many months for anxious parents to see a specialist, saving our health care system tens of millions of dollars.
You have to see how a Canadian AI company called Croptimistic is helping farmers precisely map their soil. This technology allows them to use less fertilizer, while increasing crop yield, making our food system more resilient and more affordable.
World-first: therapy to make cells young again trialled in a person
Boston-based biotechnology company Life Biosciences has launched the first-in-human clinical trials of a pioneering “partial cellular reprogramming” technique designed to treat optic nerve damage caused by glaucoma and NAION. Based on previous genetic research, the therapy utilizes a modified virus to deliver three youth-restoring genes to retinal cells, aiming to reverse cellular aging while preserving their specialized functions. Addressing the critical risk of inducing cancer through uncontrolled cell division, the protocol incorporates a vital safety switch: the rejuvenating genes are only activated in the presence of the antibiotic doxycycline. The eye was strategically selected for these initial trials because its relative isolation minimizes the risk of systemic, life-threatening side effects. Involving up to 12 patients, this groundbreaking study serves as a crucial test not only for the potential restoration of vision but for the safety, viability, and future reputation of partial reprogramming as a broader anti-aging and regenerative medicine therapy.
A participant in a landmark clinical trial has been given a cellular-reprogramming treatment that aims to rejuvenate damaged cells in the eye.
Reading the Galaxy’s Past
Every galaxy you’ve ever seen in a photograph is hiding something. Beyond the glowing disc of stars and gas that the camera captures lies a vast, ghostly outer region called a halo, too faint to see easily but packed with clues about how that galaxy came to be. ESA has just formally committed to a mission designed to reveal those hidden haloes in unprecedented detail, and in doing so, finally answer one of the most fundamental questions in astronomy: how did galaxies like our own Milky Way form?
We now know how to make the lab-grown tiny brains conscious

Nanoparticles from tattoos circulate inside the body, study finds
The elements that make up the ink in tattoos travel inside the body in micro and nanoparticle forms and reach the lymph nodes, according to a study published in Scientific Reports on 12 September by scientists from Germany and the ESRF, the European Synchrotron, Grenoble (France). It is the first time researchers have found analytical evidence of the transport of organic and inorganic pigments and toxic element impurities as well as in depth characterization of the pigments ex vivo in tattooed tissues. Two ESRF beamlines were crucial in this breakthrough.
“When someone wants to get a tattoo, they are often very careful in choosing a parlour where they use sterile needles that haven’t been used previously. No one checks the chemical composition of the colours, but our study shows that maybe they should,” explains Hiram Castillo, one of the authors of the study and scientist at the ESRF.
The reality is that little is known about the potential impurities in the colour mixture applied to the skin. Most tattoo inks contain organic pigments, but also include preservatives and contaminants like nickel, chromium, manganese or cobalt. Besides carbon black, the second most common ingredient used in tattoo inks is titanium dioxide (TiO2), a white pigment usually applied to create certain shades when mixed with colorants. TiO2 is also commonly used in food additives, sunscreens and paints. Delayed healing, along with skin elevation and itching, are often associated with white tattoos, and by consequence with the use of TiO2.
