Magnetic skyrmions (MSks) are swirling patterns of magnetization that form inside certain magnetic materials. They can behave like actual particles in many ways, exhibiting a stable internal structure and distinct boundaries. Because they are extremely small and can be pushed
Seeing inside an object is one thing; seeing exactly what it is made of, in three dimensions, is far more difficult. Now, researchers at Bar-Ilan University and collaborating institutions have developed a new X-ray imaging technique that can map the three-dimensional chemical
Researchers have developed a new computational model that accounts for the effects of aging on our eyes' ability to discriminate color. It could help guide lighting designs that make it easier for older adults to perceive colors while preserving the expected appearance for
A research team led by Jiyoung Lee, a professor in the Department of Media and Communication, has worked with international researchers to uncover how visual contrast across social media feeds influences how quickly users spot visual misinformation.
As ocean temperatures rise, corals' ability to withstand and adapt to heat stress is critical for the future of coral reefs. Many reef-building corals already live near their upper thermal limits, making them vulnerable to bleaching and, with prolonged stress, mortality.
Rats are on the ballot in Canadian municipal elections this fall, with several political parties promising to tackle city rat problems. While rats may seem like a niche election issue, they can point to broader societal concerns about housing, public services and civic
Nature has blessed us with brains that are hardwired to find patterns and recognize faces, so it’s no surprise we tend to notice faces even where there aren’t any. Although they may be better educated, the humans at NASA are no different than the rest of us. They recently
A new ice sheet model developed by glaciologists at the University of California, Irvine and NASA's Jet Propulsion Laboratory projects that the melting of Thwaites Glacier in West Antarctica will contribute up to 30 millimeters (1.2 inches) of sea level rise by 2100—twice
You sit down to meditate. A conversation returns, then thoughts. You bring your attention back to the breath. Sometimes, after many such returns, the effort eases. Thoughts lose their urgency, while awareness remains clear. Less occupies the mind, yet the moment still feels
Global warming is often treated as synonymous with climate change, but rising temperatures are only one consequence of the human-driven phenomenon. Changes in rainfall patterns are another, but their effects on ecosystems are less understood.
For decades, physicists have sought a practical two-dimensional topological insulator: an ultrathin material whose interior blocks electricity but whose edges conduct it. In ordinary wires, electrons constantly bounce off imperfections, losing energy. But along the edges of a
Silicon carbide (SiC) is a ceramic known for its excellent heat resistance and chemical stability, which makes it attractive for a wide range of applications like electronics, catalysts and energy-related materials. However, SiC generally requires high-temperature processing,
