5-12-2023 Boiled bubbles jump to carry more heat The topic of water and the way it can move producing water droplets that leap - propelled by surface tension - and frost that jumps - by way of electrostatics - is a central focus of a group of scientists. Having incorporated the two phases of liquid and solid in the first two volumes of their research, their third volume investigates a third phase, with boiling water.
5-12-2023 New wearable communication system offers potential to reduce digital health divide Researchers developed a wearable device that can transmit health data 2,400 times the distance of Wi-Fi without significant network infrastructure.
5-12-2023 Needle-free ultrasound vaccine delivery Researchers are investigating the potential of a painless, needle-free vaccine delivery by ultrasound. The method uses cavitation, which is the formation and popping of bubbles in response to a sound wave. Though initial in vivo tests reported 700 times fewer vaccine molecules were delivered by the cavitation approach compared to conventional injection, the cavitation approach produced a higher immune response. The researchers theorize this could be due to the immune-rich skin the ultrasonic delivery targets. The result is a more efficient vaccine that could help reduce costs and increase efficacy.
5-12-2023 Snail-inspired robot could scoop ocean microplastics Inspired by a small and slow snail, scientists have developed a robot protype that may one day scoop up microplastics from the surfaces of oceans, seas and lakes.
5-12-2023 Teaching physics from the din of flying discs The sound a disc makes while soaring through the air is full of information about how fast the disc is flying and how quickly it spins. This inspired Kyle S. Dalton of Penn State University to combine disc golf and acoustics into an interactive acoustic signal processing lesson. He set three microphones in a line and connected them to equipment that converts each microphone's signal to a data point. Then he threw a disc with a small whistle mounted on top and recorded the flying disc's acoustical signal. The resulting dataset can be used to learn basic processing tools and practice data visualization.
5-12-2023 Tracking undetectable space junk Satellite and spacecraft operators may finally be able to detect small pieces of debris orbiting Earth using a new approach. Colliding pieces of space debris emit electric signals that could help track small debris littering Earth's orbit, potentially saving satellites and spacecraft.
5-12-2023 Generative model unveils secrets of material disorder A new article proposes a simple and effective hybrid generative model that can predict unseen domain boundaries in synthesized materials with limited observations, without the need for expensive calculations or simulations. The study highlights the potential of simple and interpretable machine learning models in describing and understanding the nature and origin of disorder in complex materials, leading to improved functional materials design.
5-12-2023 10-billion-year, 50,000-light-year journey to black hole A star near the supermassive black hole at the center of the Milky Way Galaxy originated outside of the Galaxy according to a new study. This is the first time a star of extragalactic origin has been found in the vicinity of the super massive black hole.
5-12-2023 Breakthroughs in nanosized contrast agents and drug carriers through self-folding molecules Self-folding polymers containing gadolinium forming nanosized complexes could be the key to enhanced magnetic resonance imaging and next-generation drug delivery. Thanks to their small size, low toxicity, and good tumor accumulation and penetration, these complexes represent a leap forward in contrast agents for cancer diagnosis, as well as neutron capture radiotherapy.
5-12-2023 New theory unites Einstein's gravity with quantum mechanics The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a quantum theory of gravity, string theory and loop quantum gravity. But a new theory challenges that consensus and takes an alternative approach by suggesting that spacetime may be classical - that is, not governed by quantum theory at all.
5-12-2023 Quantum physics: Superconducting Nanowires Detect Single Protein Ions An international research team has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% quantum efficiency and exceed the detection efficiency of conventional ion detectors at low energies by a factor of up to a 1,000. In contrast to conventional detectors, they can also distinguish macromolecules by their impact energy. This allows for more sensitive detection of proteins and it provides additional information in mass spectrometry.
5-12-2023 Tiny electromagnets made of ultra-thin carbon Graphene, that is extremely thin carbon, is considered a true miracle material. An international research team has now added another facet to its diverse properties with new experiments: Experts fired short terahertz pulses at micrometer-sized discs of graphene, which briefly turned these minuscule objects into surprisingly strong magnets. This discovery may prove useful for developing future magnetic switches and storage devices.
