Author: Daryl Janzen, Observatory Manager and Instructor, Astronomy, University of Saskatchewan Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time — the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity. Space-time is frequently described as the “fabric of reality.” In some accounts […]
In polymer science, the classic division is between thermoplastics, which soften and flow when heated, and thermosets, which are permanently cross-linked and keep their shape no matter how hot they get—at least until they burn. In the last decade, researchers have discovered a fascinating new class of materials called vitrimers, which sit between these two […]
What gives rise to human consciousness? Are some parts of the brain more important than others? Scientists began tackling these questions in more depth about 35 years ago. Researchers have made progress, but the mystery of consciousness remains very much alive. In a recently published article, I reviewed over 100 years of neuroscience research to […]
Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that causes some intriguing effects. Its electron structure contributes to unconventional entropic properties at low temperatures […]

Quantum computers promise to change how we calculate the behavior of electrons in molecules, but for the machines we have now — noisy, limited in size and coherence — the challenge is to squeeze the most chemistry out of the least quantum hardware. Now, a new paper introduces a practical trick to do exactly that: […]
Attention deficit and hyperactivity disorder, known as ADHD, is the most common neurodevelopmental disorder in children worldwide, with an estimated prevalence of around 5%. Research shows that the condition often continues into adulthood in up to 90% of diagnosed children . Although ADHD has been recognised for decades, it has recently gained much greater visibility […]

Ray, Adjunct professor, Department of Ecology and Evolution, University of Toronto Through the federal Building Canada Act, “projects of national interest” are being fast-tracked while hundreds of major resource projects are already under construction or planned in the […]

A new study has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover. The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation—a name chosen from locations in Grand Canyon National Park because of the […]
Light can do remarkable things, but it has limitations. Ordinary photons are bound by diffraction, which sets a limit on how tightly they can be confined in space. This is why focusing light to spots smaller than about half its wavelength is so difficult. But in certain materials, photons couple to vibrations of atoms or […]
Imagine a clock that doesn’t have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, the same materials that are in your phone display, to create such a clock—or, at least, as close as humans can […]
