1+ week, 12+ hour ago   (1254+ words) A decade-long model study suggests major offshore wind expansion could alter moisture transport over European seas. (CREDIT: Shutterstock) Offshore wind farms do more than turn moving air into electricity. When built in large clusters, they can also slow the wind,…...

2+ week, 14+ hour ago   (962+ words) A powerful pulsed magnet expands the shock layer around spacecraft models, advancing a possible new approach to surviving reentry heat. (CREDIT: Shutterstock) A spacecraft plunging into an atmosphere faces an environment violent enough to heat the gas around its surface…...

2+ week, 6+ day ago   (1074+ words) An ADN green rocket thruster ignited electrically at room temperature, eliminating the need for a preheated catalyst bed. (CREDIT: Wikimedia / AI-Generated / CC BY-SA 4.0) An experimental “green” rocket thruster has fired successfully using ammonium dinitramide fuel without the catalyst bed normally…...

3+ week, 1+ day ago   (693+ words) That assumption may not hold. A team from Perimeter Institute and the University of Maryland reports that the conversion process can trigger powerful nonlinear effects in plasma. Those effects quickly disrupt the resonance that drives energy transfer, shutting the process…...

3+ week, 5+ day ago   (690+ words) Helium X-ray high-harmonic generation reaches 280 eV as correlated electrons appear to break the conventional energy cutoff. (CREDIT: U Wien) The result challenges the standard picture of high-order harmonic generation, or HHG, a process that converts laser light into coherent extreme-ultraviolet…...
