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. […]

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 […]

Diamond Light Source is the UK’s national synchotron (Image credit: Diamond Light Source) Electromagnetic (EM) radiation is incredibly useful. It enables us to transmit music wirelessly over large distances, cook food in the microwave and see the world in vivid detail. However, now more than ever, electromagnetic radiation is also crucial in […]

Albert Einsein Previously Unknown Letter Reveals Einstein’s Thinking on Bees, Birds and Physics The 1949 letter by the physicist and Nobel laureate discusses bees, birds, and whether new physics principles could come from studying animal senses. It’s a position still being realized within physics to this day, with a growing […]

MIT scientists have cooled a 10-kilogram object to a near standstill, using LIGO’s precise measurements of its 40-kilogram mirrors. Shown here are LIGO optics technicians examining one of LIGO’s mirrors. Credit: Caltech/MIT/LIGO Lab The results open possibilities for studying gravity’s effects on relatively large objects in quantum states. To the […]
