(Phys.org) —A team of Canadian researchers has found that anthropogenic noise (noise created by people that impacts other species) in urban areas leads to less songbird diversity. In their paper published in the journal ...
Using the Hard X-ray Modulation Telescope (HXMT), astronomers from Shanghai Astronomical Observatory in China have detected a low frequency, quasi-periodic oscillation in a black hole high mass X-ray binary known as Cygnus ...
An "artificial cricket hair" used as a sensitive flow sensor has difficulty detecting weak, low-frequency signals – they tend to be drowned out by noise. But now, a bit of clever tinkering with the flexibility of the tiny ...
