Professors Fraser Stoddart and David Williams successfully link complex synthetic molecules, enabling the creation of molecular chains with various applications in information storage systems and molecular computing. The achievement represents a significant step towards storing data within molecules smaller than a grain of salt.
A new study by the National Science Foundation reveals that basic college science courses primarily serve as a filter for promising students, leaving the majority without a deep understanding of science. This has significant implications for the quality of teacher education and the nation's pursuit of world-class research.
A new set of curriculum guides, developed with NSF support, helps teachers stimulate students' curiosity about life in the universe. The guides provide tools for elementary school teachers to explore topics like planetary systems and extraterrestrial life.
The ACE spacecraft, a NASA mission to study the nature and origin of energetic particles from the sun and beyond our solar system, is nearing completion at the Johns Hopkins University Applied Physics Laboratory. The spacecraft will provide advance warning of powerful geomagnetic storms that can disrupt power grids and communications o...
