Solar sails rely upon pressure exerted by sunlight on large surfaces. Get the sail closer to the sun and, not surprisingly, efficiency increases. A proposed new mission called Mercury Scout aims to take advantage of this ...
Focusing a tailored laser beam through transparent glass can create a tiny spot inside the material. Researchers at Tohoku University have reported on a way to use this small spot to improve laser material processing, boosting ...
Researchers from Huazhong University of Science and Technology proposed a pixelated programmable photonic integrated circuit (PICs) with record-high 20-level intermediate states of phase change materials (PCMs).
During cell division, a ring forms around the cell equator, which contracts to divide the cell into two daughter cells. Together with researchers from Heidelberg, Dresden, Tübingen and Harvard, Professor Jan Kierfeld and ...
In nanomaterials, shape is destiny. That is, the geometry of the particle in the material defines the physical characteristics of the resulting material.
Toughening has always been an important research direction of structure ceramics. The addition of secondary phases to the ceramic matrix to prepare composite ceramics is an effective toughening pathway in the field of structure ...
After more than 70 successful flights, a broken rotor ended the remarkable and groundbreaking Ingenuity helicopter mission on Mars. Now, NASA is considering how a larger, more capable helicopter could be an airborne geologist ...
Researchers from the University of Southampton have developed technology to help scientists observe proteins in motion. Understanding how proteins move will allow novel drugs to be designed.
NASA engineers will test a suite of new laser technologies from an aircraft this summer for Earth science remote sensing. Called "lidar," the instruments could also be used to improve models of the moon's shape and aid the ...
Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to "green corridors" formed ...
