Published Ultrasound gave us our first baby pictures can it also help the blind see?
(via sciencedaily.com) While there are no successful non-invasive therapeutics currently available for the treatment of vision loss, researchers at have come up with a new idea to address this growing problem. Currently, ophthalmologists use electronic technology to directly stimulate retinal neurons by implanting electrode devices inside the eye, a technique that requires expensive and invasive surgery. A research team is now exploring a non-surgical solution that could restore sight by using another of the five senses: Sound.
Published Most precise ever measurement of W boson mass to be in tension with the Standard Model
(via sciencedaily.com) Scientists have achieved the most precise measurement to date of the mass of the W boson, one of nature's force-carrying particles. The measured value shows tension with the value expected based on the Standard Model of particle physics.
Published 'Ears' for rover Perseverance's exploration of Mars
(via sciencedaily.com) Scientists have built instruments to give humans eyes and a nose on Mars -- and now they are helping add ears as well.
Published Dual-mode endoscope offers unprecedented insights into uterine health
(via sciencedaily.com) A new endoscope design that combines ultrasound with optical coherence tomography can assess the structural features of the endometrium with unprecedented detail. This dual-mode endoscope could help doctors diagnose infertility problems that are related to endometrial receptivity with greater accuracy than current imaging technologies.
Published The Rule of Two helps make spaces sound better
(via sciencedaily.com) Researchers developed a new acoustic measurement technique in a room with more acoustic combinations than there are ants on Earth.
Published Physicists 'shine' light on inner details and breakup of simple nucleus
(via sciencedaily.com) Scientists have found a new way to 'see' inside the simplest atomic nuclei to better understand the 'glue' that holds the building blocks of matter together. The results come from collisions of photons (particles of light) with deuterons, the simplest atomic nuclei (made of just one proton bound to one neutron). The photons act somewhat like an x-ray beam to provide the first glimpse of how particles called gluons are arranged within the deuteron.
Published Warming oceans are getting louder
(via sciencedaily.com) Climate change is speeding sound transmission in the oceans and the way it varies over the globe with physical properties of the oceans. Two 'acoustic hotspots' of future sound speed increases are predicted east of Greenland and in the Northwest Atlantic Ocean, East of Newfoundland. In these locations, the average speed of sound is likely to increase by more than 1.5% if 'business-as-usual' high rates of greenhouse gas emissions continue through 2100.
Published New pumpkin shaped nucleus radiates protons with record setting rate
(via sciencedaily.com) A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized.
Published Concert hall acoustics for non-invasive ultrasound brain treatments
(via sciencedaily.com) Engineers have developed a device that is a first step to enabling noninvasive, ultrasound-based therapies for the brain. For example, ultrasound waves are currently being used in clinical trials to treat epilepsy.
Published Quantum dots shine bright to help scientists see inflammatory cells in fat
(via sciencedaily.com) To accurately diagnose and treat diseases, doctors and researchers need to see inside bodies. Medical imaging tools have come a long way since the humble x-ray, but most existing tools remain too coarse to quantify numbers or specific types of cells inside deep tissues of the body. Quantum dots can do that, according to new research in mice.
Published New acoustic fabric converts audible sounds into electrical signals
(via sciencedaily.com) Researchers have developed a new acoustic fabric converts audible sounds into electrical signals. They designed a fabric that works like a microphone, converting sound first into mechanical vibrations, then into electrical signals, similarly to how our ears hear.
Published Nuclear reactor power levels can be monitored using seismic and acoustic data
(via sciencedaily.com) Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study.
Published Gravitational wave mirror experiments can evolve into quantum entities
(via sciencedaily.com) Scientists review research on gravitational wave detectors as a historical example of quantum technologies and examine the fundamental research on the connection between quantum physics and gravity. The team examined recent gravitational wave experiments, showing it is possible to shield large objects from strong influences from the thermal and seismic environment to allow them to evolve as one quantum object. This decoupling from the environment enables measurement sensitivities that would otherwise be impossible.
Published Acoustic propulsion of nanomachines depends on their orientation
(via sciencedaily.com) Scientists have now found answers to central questions which had previously stood in the way of acoustic propulsion of nanoparticles.
Published Physicists show how frequencies can easily be multiplied without special circuitry
(via sciencedaily.com) A new discovery by physicists could make certain components in computers and smartphones obsolete. The team has succeeded in directly converting frequencies to higher ranges in a common magnetic material without the need for additional components. Frequency multiplication is a fundamental process in modern electronics.
Published Selecting the right structural materials for fusion reactors
(via sciencedaily.com) Do two promising structural materials corrode at very high temperatures when in contact with 'liquid metal fuel breeders' in fusion reactors? Researchers now have the answer. This high-temperature compatibility of reactor structural materials with the liquid breeder -- a lining around the reactor core that absorbs and traps the high energy neutrons produced in the plasma inside the reactor -- is key to the success of a fusion reactor design.
Published Self-sustained divertor oscillation mechanism identified in fusion plasma experiment
(via sciencedaily.com) To harness the forces that power the Sun, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous soup called plasma. The plasma can rip through any material on Earth, so it must be confined by magnetic fields -- but it can only be controlled for short periods. Now, in a first step to prolonged control, researchers have discovered that the underlying mechanism mirrors the unlikely biological predator-prey model.
Published Ultrasound scan can diagnose prostate cancer
(via sciencedaily.com) An ultrasound scan can be used to detect cases of prostate cancer, according to new research.
Published Ultrasounds for endangered abalone mollusks
(via sciencedaily.com) The world's abalone are threatened, endangered or otherwise vulnerable in nearly every corner of the planet. If only we could wave a magic wand to know when abalone are ready to reproduce, without even touching them. Scientists have now found that wand -- although it isn't magic, and it only looks like a wand. It's an ultrasound transducer, and it can be used to quickly and noninvasively detect when abalone are ready to spawn, they report in a study this week.
Published Deep neural network to find hidden turbulent motion on the sun
(via sciencedaily.com) Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solar astronomy and other fields such as plasma physics, fusion science, and fluid dynamics.
