NMR measurements and previously published specific-heat data rule out earlier claims of strontium ruthenate’s spin-triplet superconductivity.
A sheared magnetic loop in the Sun’s corona can give rise to a thinning sheet of electrical current, magnetic reconnection, and tension forces strong enough to hurl material into space.
Issues and Events
Experts say lithium-ion batteries will be overtaken for grid-scale energy-storage applications by other battery technologies and nonchemical storage.
The medical industry is substituting x-ray sources for cesium-based blood irradiators. Other industries are also exploring alternative technologies.
Scientists can help by partnering with museums, out-of-school programs, schools, organizations that develop instructional materials, or other educational projects.
First envisioned for elucidating crystalline structures, the technique is now used for high-resolution lensless imaging, wavefront sensing, and more.
Many transparent animals rely for survival on structures built from their own mucus. To study such organisms deep underwater, researchers are using robots outfitted with lasers.
