Published Cybersecurity education varies widely in US
(via sciencedaily.com) Original source Cybersecurity programs vary dramatically across the country, a review has found. The authors argue that program leaders should work with professional societies to make sure graduates are well trained to meet industry needs in a fast-changing field. A research team found a shortage of research in evaluating the instructional approaches being used to teach cybersecurity. The authors also contend that programs could benefit from increasing their use of educational and instructional tools and theories.
Published Experiment opens door for millions of qubits on one chip
(via sciencedaily.com) Original source Researchers have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.
Published VR may pose privacy risks for kids: A new study finds parents aren't as worried as they should be
(via sciencedaily.com) Original source New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.
Published Biomechanical dataset for badminton performance analysis
(via sciencedaily.com) Original source In the sports industry, player data collection aids in personalized training feedback. Researchers have now gathered a detailed dataset and laid the foundation for delivering coaching assistance and feedback through the same. Utilizing wearable sensors and machine learning, their dataset offers real-time feedback and optimized movement suggestions. With over 7,763 badminton swings analyzed, stroke quality assessment offers valuable insights, making badminton training more accessible and affordable.
Published Stretchable e-skin could give robots human-level touch sensitivity
(via sciencedaily.com) Original source A stretchy electronic skin could equip robots and other devices with the same softness and touch sensitivity as human skin, opening up new possibilities to perform tasks that require a great deal of precision and control of force.
Published Unveiling a polarized world -- in a single shot
(via sciencedaily.com) Original source Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock the vast potential of polarization imaging for a range of existing and new applications, including biomedical imaging, augmented and virtual reality systems and smart phones.
Published Science has an AI problem: This group says they can fix it
(via sciencedaily.com) Original source A team of 19 prominent researchers has published guidelines for the responsible use of machine learning in science. They say it could avert a crisis that's smoldering in every field.
Published Physicists build new device that is foundation for quantum computing
(via sciencedaily.com) Original source Scientists have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity between a qubit, the fundamental unit of quantum computing, and a microwave-resonant cavity. The ability to precisely tune the degree of nonreciprocity is an important tool to have in quantum information processing. In doing so, the team derived a general and widely applicable theory that simplifies and expands upon older understandings of nonreciprocity so that future work on similar topics can take advantage of the team's model, even when using different components and platforms.
Published Researchers unlock potential of 2D magnetic devices for future computing
(via sciencedaily.com) Original source A research team has created an innovative method to control tiny magnetic states within ultrathin, two-dimensional van der Waals magnets -- a process akin to how flipping a light switch controls a bulb.
Published New computer algorithm supercharges climate models and could lead to better predictions of future climate change
(via sciencedaily.com) Original source A study describes a new computer algorithm which can be applied to Earth System Models to drastically reduce the time needed to prepare these in order to make accurate predictions of future climate change. During tests on models used in IPCC simulations, the algorithm was on average 10 times faster at spinning up the model than currently-used approaches, reducing the time taken to achieve equilibrium from many months to under a week.
Published Virtual reality environment for teens may offer an accessible, affordable way to reduce stress
(via sciencedaily.com) Original source Working with teens, researchers designed RESeT: a snowy virtual world with six activities intended to improve mood. In a 3-week study of 44 teens, researchers found that most of the teens used the technology about twice a week without being prompted and reported lower stress levels after using the environment.
Published Improved AI process could better predict water supplies
(via sciencedaily.com) Original source A new computer model uses a better artificial intelligence process to measure snow and water availability more accurately across vast distances in the West, information that could someday be used to better predict water availability for farmers and others. The researchers predict water availability from areas in the West where snow amounts aren't being physically measured.
Published Researchers develop a new way to instruct dance in Virtual Reality
(via sciencedaily.com) Original source Virtual reality dance made easier with crowd wave technique. Open source code can be downloaded for Quest 2 and 3.
Published Computer scientists unveil novel attacks on cybersecurity
(via sciencedaily.com) Original source Researchers have found two novel types of attacks that target the conditional branch predictor found in high-end Intel processors, which could be exploited to compromise billions of processors currently in use.
Published From disorder to order: Flocking birds and 'spinning' particles
(via sciencedaily.com) Original source Researchers have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing.
Published New circuit boards can be repeatedly recycled
(via sciencedaily.com) Original source Researchers have developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss.
