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. Full Story: Eos Complete ape genomes offer insights into human evolution Researchers […]
A quiet revolution is unfolding in the study of distant galaxies, one that lets astronomers pinpoint individual stars across the vast gulfs of time and space. Using the James Webb Space Telescope (JWST), a team of researchers has identified over 40 individual stars in a single galaxy located halfway across the observable universe. These stars […]
Author: Cédric M. John, Professor and Head of Data Science for the Environment and Sustainability, Queen Mary University of London Nearly three fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth’s oceans were once green, in […]
An international team of scientists has, for the first time, directly observed catalysis in-action at the atomic level. In mesmerizing new videos, single atoms move and shake during a chemical reaction that removes hydrogen atoms from an alcohol molecule. By viewing the process in real time, the researchers discovered several short-lived intermediate molecules involved in […]
