Scientists research effects of infrasonic vibrations in humans

It is known that the human body can generate mechanical vibrations at very low frequencies, so-called infrasonic waves. Such low-frequency vibrations are produced by physiological processes—heartbeats, respiratory movements, ...

How science is giving voice to mummies such as Otzi the Iceman

Researchers recently managed to recreate the voice of 5,300-year-old Ötzi the iceman by recreating his vocal tract. The technology is promising and could be used to digitally produce the voices of other mummified remains. ...

Driving the performance of nanosystems to the limit

A joint CEA / University of Grenoble-Alpes research team, together with international partners, has developed a diagnostic technique capable of identifying performance problems in nanoresonators, a type of nanodetector used ...

The most accurate optical single-ion clock worldwide

Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically ...

New device converts DC electric field to terahertz radiation

Terahertz radiation, the no-man's land of the electromagnetic spectrum, has long stymied researchers. Optical technologies can finagle light in the shorter-wavelength visible and infrared range, while electromagnetic techniques ...

3Qs: Could circuits' face-lift mean faster, smaller phones?

Imagine a cell phone that's half the size with longer battery time and better performance. That could become a reality thanks to new research by Nian Sun, associate professor of electrical and computer engineering at Northeastern. ...
