In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

New data on baryon acoustic oscillations strengthen the case for a local cosmic void. The finding offers a possible solution ...

As many believe, the Big Bang started our universe. But not everyone is aware that the early world is nothing like what we can see these days. There's no stars, planets, galaxies or nebulas. For a bit ...

Scientists at UC Santa Barbara have recently characterized these low-frequency signals to track breaking ocean waves ...

The celestial music released from the sun suggests that its outer layer has grown weaker over the years, according to new research from the United Kingdom. The sun releases sound waves, and like a ...

Remember a few weeks ago when the tropics were quiet in the Atlantic, yet we had three to four tropical systems in the Pacific, and now that trend has seemingly flipped? There's a reason for that.
