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 Electrical noise stimulation applied to the brain could be key to boosting math learning
(via sciencedaily.com) Exciting a brain region using electrical noise stimulation can help improve mathematical learning in those who struggle with the subject, according to a new study.
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 Quantum computer unveils atomic dynamics of light-sensitive molecules
(via sciencedaily.com) Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
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 Researchers use mathematical modeling and dynamic biomarkers to characterize metastatic disease during adaptive therapy
(via sciencedaily.com) Researchers demonstrate how mathematical modeling combined with dynamic biomarkers can be used to characterize metastatic disease and identify appropriate therapeutic approaches to improve patient outcomes.
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 Scientists uncover a surprising connection between number theory and evolutionary genetics
(via sciencedaily.com) An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists has uncovered an unexpected link between pure mathematics and genetics, that reveals key insights into the structure of neutral mutations and the evolution of organisms.
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 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 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 Researcher turns one of the basic rules of construction upside down
(via sciencedaily.com) Original source Structural engineers are familiar with seventeenth-century scientist Robert Hooke's theory that a hanging chain will mirror the shape of an upstanding rigid arch. However, new research now shows that this common-held belief is incorrect because, regardless of the similarities, the hanging chain and the arch are two incompatible mechanical systems.
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 GPT detectors can be biased against non-native English writers
(via sciencedaily.com) Original source Researchers show that computer programs commonly used to determine if a text was written by artificial intelligence tend to falsely label articles written by non-native language speakers as AI-generated. The researchers caution against the use of such AI text detectors for their unreliability, which could have negative impacts on individuals including students and those applying for jobs.
Published Board games are boosting math ability in young children
(via sciencedaily.com) Board games based on numbers, like Monopoly, Othello and Chutes and Ladders, make young children better at math, according to a comprehensive review of research published on the topic over the last 23 years.
Published Number cruncher calculates whether whales are acting weirdly
(via sciencedaily.com) Original source We humans can be a scary acquaintance for whales in the wild. This includes marine biologists tagging them with measuring devices to understand them better. These experiences can make whales behave erratically for a while. Such behaviour can affect research quality and highlights an animal ethics dilemma. Now, researchers have figured out how to solve the problems with math.
Published Deciphering the thermodynamic arrow of time in large-scale complex networks
(via sciencedaily.com) A solution for temporal asymmetry -- or entropy production -- in thermodynamics has been developed to further our understanding of the behavior of biological systems, machine learning, and AI tools. The researchers worked on the time-irreversible Ising model dynamics caused by asymmetric connections between neurons.
Published Robotic glove that 'feels' lends a 'hand' to relearn playing piano after a stroke
(via sciencedaily.com) Original source A new soft robotic glove is lending a 'hand' and providing hope to piano players who have suffered a disabling stroke or other neurotrauma. Combining flexible tactile sensors, soft actuators and AI, this robotic glove is the first to 'feel' the difference between correct and incorrect versions of the same song and to combine these features into a single hand exoskeleton. Unlike prior exoskeletons, this new technology provides precise force and guidance in recovering the fine finger movements required for piano playing and other complex tasks.
Published Combining maths with music leads to higher scores, suggests review of 50 years of research
(via sciencedaily.com) Original source Children do better at maths when music is a key part of their lessons, an analysis of almost 50 years of research on the topic has revealed.
