Published Theory can sort order from chaos in complex quantum systems
(via sciencedaily.com) Theoretical chemists have developed a theory that can predict the threshold at which quantum dynamics switches from 'orderly' to 'random,' as shown through research using large-scale computations on photosynthesis models.
Published New technology turns smartphones into RFID readers, saving costs and reducing waste
(via sciencedaily.com) Imagine you can open your fridge, open an app on your phone and immediately know which items are expiring within a few days. This is one of the applications that a new technology would enable.
Published James Webb spots super old, massive galaxies that shouldn't exist
(via sciencedaily.com) A team of international researchers have identified six candidate galaxies that existed roughly 500 to 700 million years after the Big Bang and are about as big as the modern Milky Way Galaxy -- a feat that scientists didn't think was possible.
Published Improving the performance of satellites in low Earth orbit
(via sciencedaily.com) On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.
Published The switch made from a single molecule
(via sciencedaily.com) Researchers have demonstrated a switch, analogous to a transistor, made from a single molecule called fullerene. By using a carefully tuned laser pulse, the researchers are able to use fullerene to switch the path of an incoming electron in a predictable way. This switching process can be three to six orders of magnitude faster than switches in microchips, depending on the laser pulses used. Fullerene switches in a network could produce a computer beyond what is possible with electronic transistors, and they could also lead to unprecedented levels of resolution in microscopic imaging devices.
Published Proposed quantum device may succinctly realize emergent particles such as the Fibonacci anyon
(via sciencedaily.com) Tenacity has taken a roadblock and turned it into a possible route to the development of quantum computing.
Published Securing supply chains with quantum computing
(via sciencedaily.com) New research in quantum computing is moving science closer to being able to overcome supply-chain challenges and restore global security during future periods of unrest.
Published When the light is neither 'on' nor 'off' in the nanoworld
(via sciencedaily.com) Scientists detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips.
Published Smash or pass? This computer can tell
(via sciencedaily.com) Could an app tell if a first date is just not that into you? Engineers say the technology might not be far off. They trained a computer to identify the type of conversation two people were having based on their physiological responses alone.
Published Chromo-encryption method encodes secrets with color
(via sciencedaily.com) In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published Computer model IDs roles of individual genes in early embryonic development
(via sciencedaily.com) Computer software can predict what happens to complex gene networks when individual genes are missing or dialed up more than usual. Mapping the roles of single genes in these networks is key to understanding healthy development and finding ways to regrow damaged cells and tissues. Understanding genetic errors could provide insight into birth defects, miscarriage or even cancer.
Published Virtual and augmented reality: Researchers pioneer process to stack micro-LEDs
(via sciencedaily.com) Researchers are using emerging technology to demonstrate a process that will enable more immersive and realistic virtual and augmented reality displays with the world's smallest and thinnest micro-LEDs.
Published HETDEX reveals galaxy gold mine in first large survey
(via sciencedaily.com) The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) announced their first publicly released catalog of astronomical objects. Over 200,000 astronomical objects including distant stars and galaxies have been mapped in 3D for the first time. Astronomers will use the data to better determine the Hubble constant, used to gauge the expansion of the universe. Possible 'naked black hole' early highlight of science results from HETDEX survey. TACC systems Corral, Stampede2, and Maverick were used in the data analysis and storage. Data publicly available through JupyterHub notebooks.
Published Scientists boost quantum signals while reducing noise
(via sciencedaily.com) Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.
Published New AI technology could change game prep for Super Bowl teams
(via sciencedaily.com) New artificial intelligence technology being developed by engineers could significantly cut down on the time and cost that goes into film study for Super Bowl-bound teams (and all NFL and college football teams), while also enhancing game strategy by harnessing the power of big data.
Published Scientists make major breakthrough in developing practical quantum computers that can solve big challenges of our time
(via sciencedaily.com) Researchers have demonstrated that quantum bits (qubits) can directly transfer between quantum computer microchips and demonstrated this with record-breaking connection speed and accuracy. This breakthrough resolves a major challenge in building quantum computers large and powerful enough to tackle complex problems that are of critical importance to society.
Published Footprints of galactic immigration uncovered in Andromeda galaxy
(via sciencedaily.com) Astronomers have uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that of the Milky Way.
Published Solving a machine-learning mystery
(via sciencedaily.com) Researchers have explained how large language models like GPT-3 are able to learn new tasks without updating their parameters, despite not being trained to perform those tasks. They found that these large language models write smaller linear models inside their hidden layers, which the large models can train to complete a new task using simple learning algorithms.
Published Researchers focus AI on finding exoplanets
(via sciencedaily.com) New research reveals that artificial intelligence can be used to find planets outside of our solar system. The recent study demonstrated that machine learning can be used to find exoplanets, information that could reshape how scientists detect and identify new planets very far from Earth.
