Collisions of high energy particles produce "jets" of quarks, anti-quarks, or gluons. Due to the phenomenon called confinement, scientists cannot directly detect quarks. Instead, the quarks from these collisions fragment ...

(Phys.org)—Although vacuum tubes were the basic components of early electronic devices, by the 1970s they were almost entirely replaced by semiconductor transistors. But in the past few years, researchers have been developing ...
Specially designed vacuum suction units allow humans to climb walls. Scientists have developed a suction unit that can be used on rough surfaces, no matter how textured, and that has applications in the development of climbing ...
