HI-TECH НОВОСТИ с #waves хэштегом

Sound waves could be the next big thing in fire-fighting technology. George Mason University engineering students Seth Robertson and Viet Tran have built a new kind of fire extinguisher that uses sound waves to extinguish fires as part of their senior research project – and it has a lot of potential to work in real world applications, both in everyday households and in outer space.

Physicists have been buzzing (or rather, tweeting) about the possibility that the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment finally discovered gravitational waves. LIGO has been searching for these cosmic ripples for over a decade. Last September, it upgraded to Advanced-LIGO, a more sensitive system that's also better at filtering out noise.
