A new way to probe exotic matter aids the study of atomic and particle physics. Physicists have created a new way to observe details about the structure and composition of materials that improves upon previous methods. Conventional spectroscopy changes the frequency of light shining on a sample over time to […]

This figure shows that large-scale vortex rings are produced from the injector rim during combustion oscillations. Credit: Satomi Shima, Kosuke Nakamura, Hiroshi Gotoda, Yuya Ohmichi, and Shingo Matsuyama Rocket engines contain confined combustion systems, which are essentially combustion chambers. In these chambers, nonlinear interactions among turbulent fuel and oxidizer flows, […]

Hemispherical array of ultrasound transducers lifts objects off reflective surfaces. Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a […]

ANIMATION Radioactive molecules are sensitive to subtle nuclear phenomena and might help physicists probe the violation of the most fundamental symmetries of nature. Imagine a dust particle in a storm cloud, and you can get an idea of a neutron’s insignificance compared to the magnitude of the molecule it inhabits. […]

With its novel subterranean, triangular design, Europe’s Einstein Telescope would be a gravitational wave observatory unlike any other. ET CONCEPTUAL DESIGN TEAM It’s far from a done deal, but plans by European physicists to build a huge new gravitational wave observatory with a radical design received a boost this week. […]

An artist’s depiction of a neutron star merger. These mergers produce heavy elements like gold and platinum in abundance. Credit: Sonoma State University/A. Simonnet Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons. Nucleosynthesis first occurred within a few […]
