Published Shape-changing smart speaker lets users mute different areas of a room
(via sciencedaily.com) A team has developed a shape-changing smart speaker, which uses self-deploying microphones to divide rooms into speech zones and track the positions of individual speakers.
Published Groundbreaking research shows that the limits of nuclear stability change in stellar environments where temperatures reach billions of degrees Celsius
(via sciencedaily.com) Original source New research is challenging the scientific status quo on the limits of the nuclear chart in hot stellar environments where temperatures reach billions of degrees Celsius.
Published A system to keep cloud-based gamers in sync
(via sciencedaily.com) A new technique can synchronize media streams from different networks to multiple devices with less than 10 milliseconds of delay. The technique was demonstrated on cloud gaming, but could also be applied in AR/VR applications.
Published Researchers develop ultra-sensitive photoacoustic microscopy for wide biomedical application potential
(via sciencedaily.com) Optical-resolution photoacoustic microscopy is an up-and-coming biomedical imaging technique for studying a broad range of diseases, such as cancer, diabetes and stroke. But its insufficient sensitivity has been a longstanding obstacle for its wider application. Recently, a research team developed a multi-spectral, super-low-dose photoacoustic microscopy system with a significant improvement in the system sensitivity limit, enabling new biomedical applications and clinical translation in the future.
Published Experiencing the texture of skateboard sounds can mediate divisions new research says
(via sciencedaily.com) Experiencing the harsh sounds of skateboarding can help bridge the gulf between the joy and distaste of the noises created by the sport, a new study says.
Published Exploring light neutron-rich nuclei: First observation of oxygen-28
(via sciencedaily.com) The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists based on the first observation of their decay into oxygen-24 and three and four neutrons, respectively. Notably, the oxygen-28 nucleus is found not to be 'doubly magic' as expected in the standard shell-model picture. This study provides valuable insights into the nuclear structure.
Published Hard-of-hearing music fans prefer a different sound
(via sciencedaily.com) Researchers study the impact of hearing loss on subjects' enjoyment of different music mixes. They played different music mixes to listeners with and without hearing loss and found that those with hearing loss preferred louder lead vocals, higher frequencies, and sparser mixes with fewer frequencies overall. Previous research has found that music steadily shifted to quieter vocals and louder instrumentals leading up to 1975, meaning today's music may be less accessible to those with hearing loss.
Published Brain recordings capture musicality of speech -- with help from Pink Floyd
(via sciencedaily.com) For those with neurological or developmental disorders compromising speech, brain machine interfaces could help them communicate. But today's interfaces are slow and, from electrodes placed on the scalp, can detect letters only. The speech generated is robotic and affectless. Neuroscientists have now shown that they can reconstruct the song a person is hearing from brain recordings alone, holding out the possibility of reconstructing not only words but the musicality of speech, which also conveys meaning.
Published Researchers develop a unique quantum mechanical approach to determining metal ductility
(via sciencedaily.com) A team of scientists developed a new quantum-mechanics-based approach to predict metal ductility. The team demonstrated its effectiveness on refractory multi-principal-element alloys.
Published Nuclear spin's impact on biological processes uncovered
(via sciencedaily.com) Researchers have discovered that nuclear spin influences biological processes, challenging long-held beliefs. They found that certain isotopes behave differently in chiral environments, affecting oxygen dynamics and transport. This breakthrough could advance biotechnology, quantum biology, and NMR technology, with potential applications in isotope separation and medical imaging.
Published A wearable ultrasound scanner could detect breast cancer earlier
(via sciencedaily.com) In hopes of improving the survival rate for breast cancer patients, researchers designed a wearable ultrasound device that could allow women to detect tumors when they are still in early stages.
Published Fusion model hot off the wall
(via sciencedaily.com) Heat load mitigation is critical to extending the lifetime of future fusion device. Researchers have found a way to explain the rotational temperatures measured in three different experimental fusion devices in Japan and the United States. Their model evaluates the surface interactions and electron-proton collisions of hydrogen molecules.
Published A quick look inside a human being
(via sciencedaily.com) Original source Physicists have succeeded in making a new imaging technique ready for use on humans. Radioactive markers and radiation are not necessary for this.
Published A non-covalent bonding experience
(via sciencedaily.com) Putting a suite of new materials synthesis and characterization methods to the test, a team of scientists has developed 14 organic-inorganic hybrid materials, seven of which are entirely new.
Published Unlocking the power of molecular crystals: A possible solution to nuclear waste
(via sciencedaily.com) A team researchers has discovered molecular crystals capable of capturing iodine -- one of the most common radioactive fission products -- and other pollutants. The versatile crystals could be used for nuclear waste management and other energy-related applications and move the world closer to a net-zero future.
Published 'Stunning' discovery: Metals can heal themselves
(via sciencedaily.com) Original source Researchers announce the first observation of a self-healing metal. If harnessed, the newly discovered phenomenon could someday lead to engines, bridges and airplanes that reverse damage caused by wear and tear, making them safer and longer-lasting.
Published Search for dark matter
(via sciencedaily.com) Original source Scientists have applied a promising new method to search for dark matter particles in a particle accelerator. The method is based on the observation of the spin polarization of a particle beam in a storage ring COSY.
Published Controlling signal routing in quantum information processing
(via sciencedaily.com) Original source Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental collaboration, a team has achieved unidirectional transport of signals in pairs of 'one-way streets'. This research opens up new possibilities for more flexible signaling devices.
Published Acoustics researchers decompose sound accurately into its three basic components
(via sciencedaily.com) Original source Any sound can now be perfectly replicated by a combination of whistles, clicks, and hisses, with implications for sound processing across the media landscape.
Published Public support hydrogen and biofuels to decarbonize global shipping
(via sciencedaily.com) Original source New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.
