Abstract: We present a novel particle-grid scheme for simulating bubble and foam flow. At the core of our approach lies a particle representation that combines the computational nature of moving least ...

Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion ...

WASHINGTON — After a yearlong investigation, the National Transportation Safety Board blamed multiple systemwide failures for the midair collision of an Army Black Hawk helicopter and American ...

When it comes to cutting-edge automotive technology, arguably the most consequential pursuit of the modern era is the race to develop fully autonomous vehicles. By most estimates, we’re somewhere past ...

NASA’s Hubble Space Telescope has recorded repeated collisions between asteroids in the planetary system surrounding the star Fomalhaut, located approximately 25 light-years from Earth in the ...

When two aircraft are unknowingly on a collision course, TCAS - the Traffic Collision Avoidance System — comes alive. Alarms echo through the cockpit as the transponders on both jets communicate, ...

Norwegian technology company Vissim has secured a contract with a Qatar-based oil and gas operator to deliver a vessel collision avoidance system at an undisclosed oil field offshore Qatar. As part of ...

Nikesh Kooverjee has been contributing to the automotive sphere for 11 years. His previous roles include Digital Editor at CAR South Africa and associate editor at CarBuzz. He has always had a strong ...

Ribosomes don’t just make proteins—they can sense when something’s wrong. When they collide, they send out stress signals that activate a molecule called ZAK. Researchers uncovered how ZAK recognizes ...

Every time two beams of particles collide inside an accelerator, the universe lets us in on a little secret. Sometimes it's a particle no one has ever seen. Other times, it's a fleeting glimpse of ...
