In the quest to unravel the mysteries of the universe, scientists are turning to tiny glowing molecules and powerful microscopes to detect elusive particles. Two groundbreaking studies, one published in ACS Sensors in 2025 and another in Nature Communications in 2024, showcase innovative approaches to detecting barium ions in high-pressure xenon gas. These advancements are […]
Author: Karen K. Christensen-Dalsgaard, Assistant Professor, Department of Biological Sciences, MacEwan University In the 11th century in Cairo, the foundations for modern science were laid through the detention of an innocent man. The mathematician Abu Ali al-Hasan Ibn al-Haytham had been tasked with regulating the flow of the Nile, but when he saw the river […]
Understanding the origin of heavy elements on the periodic table is one of the most challenging open problems in all physics. In the search for conditions suitable for these elements via “nucleosynthesis,” a Los Alamos National Laboratory-led team is going where no researchers have gone before: the gamma-ray burst jet and surrounding cocoon emerging from […]
Magnetrons are high-power vacuum tubes conceived more than a century ago to produce microwaves. Their working principle involves the interaction of a cloud of electrons jumping from the cathode to the anode of the device together with a magnetic field. This spinning electron cloud trajectory induces electromagnetic fields in several resonant cavities at a certain […]
Study challenges assumptions about magnetar formation The study of the magnetar SGR 0501+4516 using Hubble and Gaia telescopes has deepened the mystery of its origins. Previously thought to be associated with the supernova remnant HB9, the magnetar shows no connection to it, which suggests that SGR 0501+4516 may have formed through an alternative process, such […]
Imagine a glass of water or a bottle of ethanol. These are molecular liquids, substances where molecules are free to move but are still closely packed, interacting with each other through forces like hydrogen bonds or weaker attractions. Scientists have long been fascinated by how these molecules move and interact, especially at scales that are […]
Author: Jonathan Simone, Adjunct Professor of Biological Sciences, Brock University On May 20, 1875, delegates from a group of 17 countries gathered in Paris to sign what may be the most overlooked yet globally influential treaty in history: the Metre Convention. At a time when different countries (and even different cities defined weights and lengths […]
A new study suggests the universe may rotate—just extremely slowly. The finding could help solve one of astronomy’s biggest puzzles. Current models say the universe expands evenly in all directions, with no sign of rotation. This idea fits most of what astronomers observe. But it doesn’t explain the so-called Hubble tension—a long-standing disagreement between two […]
Have you ever found yourself spending five minutes talking to someone and suddenly using their words instead of your own? Say, for example, that you usually say “couch” but now suddenly you call it “sofa.” You say “TV,” but suddenly it’s “the telly.” You’ve never in your life referred to dinner as “tea” but after […]
Magma chambers influence composition of Mars’ crust A study explores the history of magma chambers on Mars, revealing how these chambers evolve over time. Numerical modelling indicates that early Mars had higher temperatures, allowing upper crustal chambers to last longer, feeding surface eruptions.
