LHC experiments observe quantum entanglement at the highest energy yet

Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bending phenomenon, which has no analog in classical physics, has been observed in a wide […]

Zirconium metals under extreme conditions found to deform in surprisingly complex ways

Materials are crucial to modern technology, especially those used in extreme environments like nuclear energy systems and military applications. These materials need to withstand intense pressure, temperature and corrosion. Understanding their lattice-level behavior under such conditions is essential for developing next-generation materials that are more resilient, cheaper, lighter and sustainable.

Nuclear theorists turn to supercomputers to map out matter’s building blocks in 3D

Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom’s nucleus—particles called hadrons that a high school student would recognize as protons and neutrons—are made up of a seething mixture of interacting quarks and gluons, known collectively as partons.

New method improves understanding of light-wave propagation in anisotropic materials

Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional differences in how they scatter light, known as anisotropy. This complexity has traditionally made it difficult to accurately measure and model their optical properties. Recently, researchers have developed a […]

Lord Kelvin: How the 19th century scientist combined research and innovation to change the world

“What got you into astrophysics?” It’s a question I’m often asked at outreach events, and I answer by pointing to my early passion for exploring the biggest questions about our universe. Well, along with seeing Star Wars at an impressionable age.
