Published Scientists use quantum biology, AI to sharpen genome editing tool
(via sciencedaily.com) Original source Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published Glow in the visible range detected for the first time in the Martian night
(via sciencedaily.com) Original source Scientists have observed, for the first time in the visible range, a glow on the night side of the planet Mars. These new observations provide a better understanding of the dynamics of the upper atmosphere of the Red Planet and its variations throughout the year.
Published Extended habitability of exoplanets due to subglacial water
(via sciencedaily.com) Original source New research promises to redefine our comprehension of habitable exoplanets. A recent study introduces the concept of subglacial liquid water as a pivotal element in broadening the boundaries of the conventional Habitable Zone.
Published Exploring the origin of nucleosynthetic isotope variations in Ryugu samples
(via sciencedaily.com) Original source The observed variations in chromium (Cr) isotope ratios in the Ryugu asteroid samples collected by Hayabusa2 likely resulted from elemental redistribution of slightly soluble Cr by water within the parent body, reveals a multinational study. The results provide useful insights for expanding our understanding of the origin and evolution of materials in our solar system.
Published Scientists find 14 new transient objects in space by peering through the 'Christmas Tree Galaxy Cluster'
(via sciencedaily.com) Original source Scientists have discovered 14 new transient objects during their time-lapse study of galaxy cluster MACS0416 -- located about 4.3 billion light years from Earth -- which they've dubbed as the 'Christmas Tree Galaxy Cluster.'
Published New findings support long-proposed process of planet formation
(via sciencedaily.com) Original source Scientists just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, they confirmed a physical process involving the drifting of ice-coated solids from the outer regions of the disk into the rocky-planet zone.
Published Physicists trap electrons in a 3D crystal
(via sciencedaily.com) Original source Physicists have trapped electrons in a pure crystal, marking the first achievement of an electronic flat band in a three-dimensional material. The results provide a new way for scientists to explore rare electronic states in 3D materials.
Published 'Hot' new form of microscopy examines materials using evanescent waves
(via sciencedaily.com) Original source A team of researchers has built a prototype microscope that does not rely on backscattered radiation, instead uses passive detection of thermally excited evanescent waves. They have examined dielectric materials with passive near-field spectroscopy to develop a detection model to further refine the technique, working to develop a new kind of microscopy for examining nanoscopic material surfaces.
Published Studies of geologic faulting on icy moons aid exploration of extraterrestrial watery worlds
(via sciencedaily.com) Original source Earth and space scientists document and reveal the mechanisms behind strike-slip faulting on the largest moon of Saturn, Titan, and Jupiter's largest moon, Ganymede.
Published Milestone moment toward development of nuclear clock
(via sciencedaily.com) Original source Physicists have started the countdown on developing a new generation of timepieces capable of shattering records by providing accuracy of up to one second in 300 billion years, or about 22 times the age of the universe.
Published Vacuum in optical cavity can change material's magnetic state without laser excitation
(via sciencedaily.com) Original source Researchers in Germany and the USA have produced the first theoretical demonstration that the magnetic state of an atomically thin material, ?-RuCl3, can be controlled solely by placing it into an optical cavity. Crucially, the cavity vacuum fluctuations alone are sufficient to change the material's magnetic order from a zigzag antiferromagnet into a ferromagnet.
Published What a '2D' quantum superfluid feels like to the touch
(via sciencedaily.com) Original source Researchers have discovered how superfluid helium 3He would feel if you could put your hand into it. The interface between the exotic world of quantum physics and classical physics of the human experience is one of the major open problems in modern physics. Nobody has been able to answer this question during the 100-year history of quantum physics.
Published Optical-fiber based single-photon light source at room temperature for next-generation quantum processing
(via sciencedaily.com) Original source Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely low temperatures. Now, researchers have developed an ytterbium-doped optical fiber at room temperature. By avoiding the need for expensive cooling solutions, the proposed method offers a cost-effective platform for photonic quantum applications.
Published Exploding stars
(via sciencedaily.com) Original source When massive stars or other stellar objects explode in the Earth's cosmic neighborhood, ejected debris can also reach our solar system. Traces of such events are found on Earth or the Moon and can be detected using accelerator mass spectrometry, or AMS for short.
Published 'Jurassic worlds' might be easier to spot than modern Earth
(via sciencedaily.com) Original source An analysis finds telescopes could better detect potential chemical signatures of life in an Earth-like exoplanet that more closely resembles the age the dinosaurs inhabited than the one we know today.
Published Bartering light for light: Scientists discover new system to control the chaotic behavior of light
(via sciencedaily.com) Original source Researchers describe a new platform for controlling the chaotic behavior of light by tailoring its scattering patterns using light itself.
Published Reverse engineering Jackson Pollock
(via sciencedaily.com) Original source Researchers combined physics and machine learning to develop a new 3D-printing technique that can quickly create complex physical patterns -- including replicating a segment of a Pollock painting -- by leveraging the same natural fluid instability that Pollock used in his work.
Published Late not great -- imperfect timekeeping places significant limit on quantum computers
(via sciencedaily.com) Original source Quantum physicists show that imperfect timekeeping places a fundamental limit to quantum computers and their applications. The team claims that even tiny timing errors add up to place a significant impact on any large-scale algorithm, posing another problem that must eventually be solved if quantum computers are to fulfill the lofty aspirations that society has for them.
Published The Crab Nebula seen in new light by NASA's Webb
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.
Published To advance space colonization, new research explores 3D printing in microgravity
(via sciencedaily.com) Original source Research into how 3D printing works in a weightless environment aims to support long-term exploration and habitation on spaceships, the moon or Mars.
