Scientists have solved the riddle behind one of the most recognisable, and annoying, household sounds: the dripping tap. And crucially, they have also identified a simple solution to stop it, which most of us already have in our kitchens.
The University of Haifa (Israel) and two teams from the IMDEA Networks Institute have developed an innovative autonomous system, SYMBIOSIS, to monitor real-time schools of fish. This system, which combines optical and acoustic technologies, will be environmentally friendly and will provide reliable information about the condition of marine fish stocks, something that at the moment is practically impossible to achieve without investing enormous resources.
Individual speech sounds -- phonemes -- are statistically associated with negative or positive emotions in several languages, new research published in the journal Cognition by Bocconi Professor Zachary Estes, his Warwick colleague James Adelman and Bocconi student Martina Cossu shows. These associations help us quickly avoid dangers, because the phoneme-emotion associations are strongest at the beginning of the word and the phonemes that are spoken fastest tend to have a negative association
Lihong Wang, Caltech's Bren Professor of Medical Engineering and Electrical Engineering, has developed a laser-sonic scanning system that can identify breast tumors quickly and safely.
Yale scientists have created a new type of silicon laser that uses sounds waves to amplify light. A study about the discovery appears June 8 in the online edition of the journal Science.
A research team led by professor YANG Jun from the Institute of Acoustics (IOA) of the Chinese Academy of Sciences designed and fabricated a 3D underwater acoustic carpet cloak (UACC) using transformation acoustics.
In a pilot study, researchers from North Carolina State University and Haverford College have used naturally arising acoustic vibrations -- or sound waves -- to monitor the state of granular materials.
Researchers at the Department of Energy's Oak Ridge National Laboratory made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice -- a discovery that may dramatically improve heat transport in insulators and enable new strategies for heat management in future electronics devices.
Scientists monitoring the vibrations of natural rock arches have found that the resonant frequencies of arches undergo dynamic changes from day to day, according to research presented at the 2018 SSA Annual Meeting.
Making tumor cells glow: medical physicists at Martin Luther University Halle-Wittenberg have developed a new method that can generate detailed three-dimensional images of the body's interior. This can be used to more closely investigate the development of cancer cells in the body. The research group presents its findings in Communication Physics, a journal published by the Nature Publishing Group.
