Researchers used FRET to study GAT1 transporters and found correlations between oligomerization state and function. The results show the power of the FRET-based approach for distinguishing among distinct states of proteins.
Researchers at U-M have developed a lab-on-a-chip device that uses sound waves to drive experimental samples through the device. This innovation replaces traditional electromechanical valves with resonance cavities, amplifying specific musical notes to create air pressure controlling droplets.
A new study finds that Richard Wagner used the acoustics of the soprano voice to create music drama with improved intelligibility and ease of production. Wagner's operas often featured vowels sung with an open mouth, which were matched to high notes in a way that enhanced both performer and listener experience.
Engineers at Georgia Tech Research Institute create a new approach to noise reduction using micro honeycomb structures that dissipate acoustic waves through viscous shear. The innovative material, developed from nickel-base superalloys, could also protect aircraft from impact by dispersing energy.
Researchers have engineered a frequency-agile metamaterial that can be tuned over a range of frequencies in the terahertz gap, opening it up to various applications. The team's innovative composite uses semiconducting materials to achieve 20% tuning of terahertz resonance across different frequencies.
A team of researchers created the first fully functional radio from a single carbon nanotube, enabling tiny wireless communication devices. The nanotube radio works by detecting incoming radio waves and vibrating at its flexural resonance frequency to receive signals, offering a new approach to making radios.
A specific resonance pattern in the brain's auditory processing region is crucial for distinguishing speech, according to researchers. The inherent rhythm of neural activity in the theta band reacts to spoken sentences by changing its phase and samples segments about a syllable's length.
Scientists at Georgia Institute of Technology developed a new nanofabrication technique by growing carbon nanotubes on micro-cantilevers, enabling precise measurement and control over the growth process. This platform allows for rapid testing of various chemistry or growth conditions, accelerating materials discovery.
Researchers suggest that interactions between viral dynamics and structured treatment interruptions may cause high fluctuations in viral load, leading to virologic failure. This challenges the effectiveness of a single, structured treatment interruption therapy for all HIV patients.
Researchers at Penn State have developed a prototype sonic gas analyzer that automatically detects gas concentrations in air/gas mixtures by analyzing pitch changes. The system can track toxic or flammable gases and detect changes as low as 0.003 percent, making it suitable for monitoring hydrogen levels in microbial fuel cells.
Researchers at NIST and CU-Boulder observed strontium atoms forming a cubic structure, with atoms flying apart in formation due to a recoil effect. The phenomenon is caused by the atoms absorbing laser energy and rapidly cooling, resulting in the creation of a 'flying structure' visible through blue fluorescence signals.
Researchers at USC have built a signal detector that only works when noise is added, using stochastic resonance to amplify weak electronic signals. The device uses carbon nanotubes and demonstrates the potential for enhanced applications in electronics and communication systems.
A study by Dr. Jeanne Moore and Tracey Crosbie found that homeworkers in professional occupations tend to find the experience more rewarding, while those with young children struggle to balance home and work responsibilities. The researchers also discovered that men and women have different experiences of homeworking.
A new method called GFT NMR increases data collection speed by orders of magnitude while increasing accuracy, potentially revolutionizing protein structure determination. This breakthrough could enable scientists to harness the power of latest NMR machines and cryogenic probes.
Researchers create near-field infrared microscope to visualize crystal vibrations in the nanometre range. The technique uses infrared light to enhance signal intensity at the tip of a scanning probe needle, revealing phonon resonance in silicon carbide crystals 200-fold brighter than gold.
Quantum Magnetics Inc. is adapting nuclear quadrupole resonance technology for landmine detection in a portable detector for U.S. marines and a vehicle-mounted system for the U.S. Army. The technology was originally developed for explosives and narcotics detection, with successful demonstrations at airport operations.
Scientists at Georgia Tech create a device that can accurately measure the mass of small particles by inducing resonance in individual carbon nanotubes. This technique has potential for weighing viruses and other sub-micron scale particles.
