For about half a century, physicists have puzzled over vibrations in glass at low temperatures. The reason: Glass carries sound waves and vibrations differently than other solids—it "vibrates differently." But why? And ...

Optomechanical microcavities are extremely small structures with diameters of less than 10 micrometers (about a tenth of a human hair) inside which light and mechanical vibrations are confined. Thanks to their small size ...

(Phys.org)—The predictive power and galvanizing influence that theoretical models routinely enjoy in physics is only rarely replicated in biology. Lord Raleigh's theory of sound perception, Francis Crick's sequence and ...
Humans can discriminate tens of thousands of odors. While we may take our sense of smell for granted, it adds immeasurably to our quality of life: the aroma of freshly brewed coffee; the invigorating smell of an ocean breeze ...

The vibrational theory of olfaction explains several aspects of odorant detection that theories based purely on receptor binding do not. It provides for additional selectivity through receptors that are tuned to specific ...
(PhysOrg.com) -- Since 1996, when biophysicist Luca Turin first suggested that quantum mechanics may help explain how we smell various odors, the idea has met with controversy. In the past 15 years, some studies have found ...
(PhysOrg.com) -- Researchers at UC Santa Barbara have provided the first clear demonstration that the theory of quantum mechanics applies to the mechanical motion of an object large enough to be seen by the naked eye. Their ...
