Imagine a sheet of material so incredibly thin it’s just one atom thick, yet it can capture and guide light in ways that defy our everyday intuition. This isn’t science fiction—it’s graphene, a wonder material made from carbon atoms arranged in a honeycomb pattern. Now, picture slicing this sheet into tiny ribbons, arranging them in […]
Author: Gabriela Radulescu, Guggenheim Postdoctoral Fellow, Smithsonian Institution As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and other spacecraft, and use radio telescopes to take in radio waves emitted by objects […]
Author: Mara Johnson-Groh, Simmons Foundation In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes puzzled astronomers. Black holes like these were not supposed to exist. Now, astronomers with the Flatiron Institute’s Center for Computational […]
Imagine electrons as tiny particles zipping through a material, each carrying two key properties: charge, which powers our everyday electronics, and spin, like a little internal compass needle that points up or down. Charge flow is what we call electric current, but spin adds a magnetic twist, opening doors to advanced technologies like more efficient […]
From the burning of wood to the action of medicines, the properties and behavior of matter are governed by the way chemical elements bond with one another. For many of the 118 known elements, the intricate electronic structures of the atoms that are responsible for chemical bonding are well understood. But for the superheavy elements […]
Authors: Roger S. Seymour, Professor Emeritus of Physiology, University of Adelaide and Edward Snelling, Faculty of Veterinary Science, University of Pretoria If you’ve ever wondered why the giraffe has such a long neck, the answer seems clear: it lets them reach succulent leaves atop tall acacia trees in Africa. Only giraffes have direct access to […]
Author: Rohini Subrahmanyam is a PhD biologist turned science journalist. Insects that tuck away wings; a protist with an accordion-like neck — studying these clever creases may inspire foldable structures for drones As the microscopic, tear-shaped Lacrymaria olor swims around hunting for food, it does something remarkable: In a blink, the tiny protist extends its […]
Author: Paul C. Sereno, Professor of Paleontology, University of Chicago Dinosaur “mummies” couldn’t have been further from my mind as I trudged up a grassy knoll on the Zerbst Ranch in east-central Wyoming, followed by University of Chicago undergraduates on a field trip linked to my “Dinosaur Science” course. As a university professor, I realized […]
If you’ve ever fallen down a Wikipedia rabbit hole—clicking link after link until you’re far from where you started—you’ve explored a network, much like physicists map connections in systems like the internet or ecosystems. Each Wikipedia article is a dot, each hyperlink a line connecting ideas. This vast web, built by millions of contributors, mirrors […]
Author: Florian Neukart, Assistant professor of Physics, Leiden University For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles and fields. Both work brilliantly in their own domains. But put them together and […]
