Taking inspiration from a popular executive toy ("Newton's cradle"), researchers at the California Institute of Technology (Caltech) have built a device -- called a nonlinear acoustic lens -- that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets. " The acoustic lens and its sound bullets (which can exist in fluids -- like air and water -- as well as in solids) have "the potential to revolutionize applications from medical imaging and therapy to the nondestructive evaluation of materials and engineering systems," says Chiara Daraio, assistant professor of aeronautics and applied physics at Caltech and corresponding author of a recent paper in the Proceedings of the National Academy of Sciences (PNAS) describing the development.
Daraio and postdoctoral scholar Alessandro Spadoni, first author of the paper, crafted their acoustic lens by assembling 21 parallel chains of stainless steel spheres into an array.

Antares is a red supergiant star in the Milky Way galaxy and the sixteenth brightest star in the nighttime sky (sometimes listed as fifteenth brightest, if the two brighter components of the Capella quadruple star system are counted as one star). The Pistol Star is a blue hypergiant and is one of the most luminous known stars in the Milky Way Galaxy. Rigel (β Ori / β Orionis / Beta Orionis) is the brightest star in the constellation Orion and the sixth brightest star in the sky, with visual magnitude 0.18. Arcturus (α Boo / α Boötis / Alpha Boötis) is the brightest star in the constellation Boötes. Humans Have Hidden Sensory System. The human body may be equipped with a separate sensory system aside from the nerves that gives us the ability to touch and feel, according to a new study.
Most of us have millions of different types of nerve endings just beneath the skin that let us feel our surroundings. However, the once-hidden and recently discovered skin sense, found in two patients, is located throughout the blood vessels and sweat glands, and most of us don't even notice it's there. "It's almost like hearing the subtle sound of a single instrument in the midst of a symphony," said senior author Frank Rice, a neuroscience professor at Albany Medical College in New York. "It is only when we shift focus away from the nerve endings associated with normal skin sensation that we can appreciate the sensation hidden in the background.
" Sensitive skin Our skin, the body's largest organ, seems to have some extraordinary qualities, as another recent study showed skin can hear. Surprise results. ScienceMagazine's Channel.
