(PhysOrg.com) -- Positronium atoms have been found to scatter off gas particles in the same way as lone electrons, a finding which could help astronomers interpret some of their more puzzling observations, and which may have ...
(PhysOrg.com) -- Scientists in Shanghai in China, have developed a waterproof cotton fabric that remains waterproof after going through a domestic wash at least 250 times.
Dramatic flares and bursts of energy - activity previously thought reserved for only the strongest magnetized pulsars - has been observed emanating from a weakly magnetised, slowly rotating pulsar. The international team ...
