Published Structural isomerization of individual molecules using a scanning tunneling microscope probe
(via sciencedaily.com) Original source An international research team has succeeded in controlling the chirality of individual molecules through structural isomerization. The team also succeeded in synthesizing highly reactive diradicals with two unpaired electrons. These achievements were made using a scanning tunneling microscope probe at low temperatures.
Published Remarkable cellular architecture and phylogenetic position of the mysterious arm-swinging protist meteora sporadica
(via sciencedaily.com) Original source Researchers studied in detail the strange protist Meteora sporadica, which swings its two lateral arms back and forth. The results of the study indicated that M. sporadica has a complex cytoskeleton that is closely related to Hemimastigophora, a group of organisms considered to be one of the deepest branches of eukaryotes.
Published Number of shark bites consistent with recent trends, with small spike in fatalities
(via sciencedaily.com) Original source There was an increase in the number of unprovoked shark attacks worldwide and an uptick in fatalities in 2023 compared to the previous year. A scientific database of global shark attacks, confirmed 69 unprovoked bites in 2023. Although this is higher than the most recent five-year average of 63 attacks, the data remain consistent with long-term trends.
Published Unveiling the generation principles of charged particles 'trion' in 2D semiconductor
(via sciencedaily.com) Original source Researchers pioneer dynamic manipulation and the generation principles of trion at the nanoscale using tip-enhanced cavity-spectroscopy.
Published Small but mighty -- study highlights the abundance and importance of the ocean's tiniest inhabitants
(via sciencedaily.com) Original source New research sheds light on tiny plankton, which measure less than 0.02mm in diameter but can make up more than 70% of the plankton biomass found in the ocean.
Published Vitamin B12 adaptability in Antarctic algae has implications for climate change, life in the Southern Ocean
(via sciencedaily.com) Original source The algae P. antarctica has two forms of the enzyme that makes the amino acid methionine, one needing B12, and one that is slower, but doesn't need it. This means it has the ability to adapt and survive with low B12 availability. The presence of the MetE gene in P. antarctica gives the algae the ability to adapt to lower vitamin B12 availability, giving it a potential advantage to bloom in the early austral spring when bacterial production is low. P. antarctica takes in the CO2 and releases oxygen through photosynthesis. Understanding its ability to grow in environments with low vitamin B12 availability can help climate modelers make more accurate predictions.
Published Direct view of tantalum oxidation that impedes qubit coherence
(via sciencedaily.com) Original source Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.
Published Scientists create effective 'spark plug' for direct-drive inertial confinement fusion experiments
(via sciencedaily.com) Original source Scientists completed several successful attempts to fire 28 kilojoules of laser energy at small capsules filled with deuterium and tritium fuel, causing the capsules to implode and produce a plasma hot enough to initiate fusion reactions between the fuel nuclei. These results demonstrate an effective 'spark plug' for direct-drive methods of inertial confinement fusion.
Published Magnesium protects tantalum, a promising material for making qubits
(via sciencedaily.com) Original source Scientists have discovered that adding a layer of magnesium improves the properties of tantalum, a superconducting material that shows great promise for building qubits, the basis of quantum computers. The scientists show that a thin layer of magnesium keeps tantalum from oxidizing, improves its purity, and raises the temperature at which it operates as a superconductor. All three may increase tantalum's ability to hold onto quantum information in qubits.
Published A sleeker facial recognition technology tested on Michelangelo's David
(via sciencedaily.com) Original source Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report on a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of Michelangelo's David just as well as an existing smartphone system.
Published A physical qubit with built-in error correction
(via sciencedaily.com) Original source Researchers have succeeded in generating a logical qubit from a single light pulse that has the inherent capacity to correct errors.
Published Clown anemonefish seem to be counting bars and laying down the law
(via sciencedaily.com) Original source We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research suggests that our marine cousins may be more cognizant than we credit them for. Fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies.
Published Tidal landscapes a greater carbon sink than previously thought
(via sciencedaily.com) Original source Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research shows that these environments are perhaps twice as effective as previously thought.
Published Physicists develop highly robust time crystal
(via sciencedaily.com) Original source Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.
Published Single proton illuminates perovskite nanocrystals-based transmissive thin scintillators
(via sciencedaily.com) Original source Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.
Published Short X-ray pulses reveal the source of light-induced ferroelectricity in SrTiO3
(via sciencedaily.com) Original source Researchers have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. They exposed the material to mid-infrared and terahertz frequency laser pulses and found that the fluctuations of its atomic positions are reduced under these conditions. This may explain why the dipolar structure is more ordered than in equilibrium and why the laser pulses induce a ferroelectric state in the material.
Published Scientists make breakthrough in quantum materials research
(via sciencedaily.com) Original source Researchers describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.
Published Floating algae a raft for juvenile pelagic fish
(via sciencedaily.com) Original source Floating macroalgal acts as a raft that provides habitat for a diverse array of juvenile oceanic fish a new study has found. The study conducted in the Ningaloo Coast World Heritage Area, Western Australia, revealed that fish were more abundant around macroalgal rafts than in open water, with eleven species of juvenile fishes associated with Sargassum rafts, and one species of both juveniles and adults.
