Nisheeta Desai, a 2020 UK graduate and now postdoctoral fellow at the Tata Institute of Fundamental Research, in collaboration with her mentor Ribhu Kaul, in the UK Department of Physics and Astronomy, has developed a theory that sheds new light on some of the biggest mysteries in theoretical physics. Their work, which recently published in Nature Physics, shows how the quantum motion of a synthetic material can be controlled by external magnetic fields. Such magnets may be key to realizing new quantum technologies.

Nature Physics, 20 May 2021 In past studies, researchers have found that C. elegans gonads generate more germ cells than needed and that only half of them grow to become oocytes, while the rest shrinks and die by physiological apoptosis, a programmed cell death that occurs in multicellular organisms. Now, scientists from the Biotechnology Center of the TU Dresden (BIOTEC), the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG), the Cluster of Excellence Physics of Life (PoL) at the TU Dresden, the Max Planck Institute for the Physics of Complex Systems (MPI-PKS), the Flatiron Institute, NY, and the University of California, Berkeley, found evidence to answer the question of what ....
Fundamental Constants Are the Future of Measurement Details Written by Adam J. Fleisher Washington, DC - In an essay titled “The end of artefacts, ” Nobel laureate and National Institute of Standards and Technology (NIST) fellow William D. Phillips details how scientists came to realize the original vision of the metric system, or the International System of Units (SI) a system of units “for all times, for all people.” With the redefinition of the kilogram in 2019, the new SI was rightly celebrated as a unifying achievement toward the democratization of science, with NIST and its international partners having collectively led the charge. ....
This artist s interpretation intends to show small grains of a reference material disappearing or floating away. Also shown are two lasers, red and blue, which represent the two different colored lasers used by our instrument. Also visible are linear molecules of carbon dioxide (collections of three balls), CO 2.
