(Phys.org)—Researchers have demonstrated that the geometry of a natural spider web can be used to design new structures that address one of the biggest challenges in sound control: reducing low-frequency noise, which is ...
A new species of dinosaur identified by Mexican paleontologists is believed to have been "very communicative" and used low-frequency sounds like elephants to talk to each other, a researcher said Friday.
